On December 3, 2018 Seattle Genetics, Inc. (Nasdaq:SGEN) and Takeda Pharmaceutical Company Limited (TSE:4502) reported that data from the ECHELON-2 phase 3 clinical trial will be presented today in an oral session at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting (Press release, Seattle Genetics, DEC 3, 2018, View Source [SID1234531850]). The data demonstrated that frontline treatment with ADCETRIS (brentuximab vedotin) in combination with CHP (cyclophosphamide, doxorubicin, prednisone) is effective in extending progression-free survival (PFS) and overall survival (OS) with a safety profile comparable to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisone), a current standard of care in patients with CD30-expressing peripheral T-cell lymphomas (PTCL). These data were also simultaneously published online in The Lancet. ADCETRIS is an antibody-drug conjugate (ADC) directed to CD30, which is expressed on the surface of several types of PTCL.

The positive topline results of the ECHELON-2 phase 3 clinical trial were previously reported in October 2018. In November 2018, ADCETRIS was approved by the U.S. Food and Drug Administration (FDA) for adults with previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing PTCL, including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with CHP. The ECHELON-2 data were the basis of a supplemental Biologics License Application (BLA), which was reviewed by the FDA under its Real-Time Oncology Review Pilot Program and approved less than two weeks after complete submission of the supplemental BLA.

"As clinicians, we are always searching for new strategies to address unmet needs in aggressive blood cancers, and ADCETRIS has proven to be one of those agents that has shown benefit for patients in multiple types of lymphoma and now in frontline PTCL," said Steven Horwitz, M.D., Department of Medicine, Lymphoma Service, Memorial Sloan Kettering Cancer Center, New York. "This research is important for patients because clinicians now have a novel approach for treating newly diagnosed patients with CD30-expressing PTCL, a group of aggressive cancers. The ECHELON-2 data demonstrates that ADCETRIS plus CHP is superior in extending both progression-free survival and overall survival compared to a current standard of care, CHOP, a multi-agent chemotherapy regimen we have been using in practice for several decades."

"This is the sixth FDA-approved indication for ADCETRIS in lymphoid malignancies and the second as a frontline treatment in combination with chemotherapy," said Roger Dansey, M.D., Chief Medical Officer at Seattle Genetics. "The data presented today at ASH (Free ASH Whitepaper) underscores that the ADCETRIS combination provides clinically meaningful benefit to patients with previously untreated PTCL and has the potential to be practice changing for these patients."

"We are pleased to share these impressive results from the ECHELON-2 trial, which build on the efficacy and safety observed with ADCETRIS in a variety of CD30-positive lymphomas," said Jesús Gómez-Navarro, M.D., Vice President and Head, Oncology Clinical Research and Development, Takeda. "The study demonstrated clinically meaningful outcomes and was the first randomized phase 3 trial in frontline PTCL to show improvement in overall survival. Establishing an optimal therapy for PTCL has been a challenge for physicians, and these findings represent the progress in addressing the unmet needs of people living with this serious disease. We look forward to working with regulatory authorities in our territory to bring a potential new treatment option to patients with PTCL."

The ECHELON-2 Trial: Results of a Randomized, Double-Blind, Active-Controlled Phase 3 Study of Brentuximab Vedotin and CHP (A+CHP) Versus CHOP in the Frontline Treatment of Patients with CD30+ Peripheral T-Cell Lymphomas (Abstract #997, oral presentation on Monday, December 3, 2018 at 6:15 p.m. PT at the San Diego Convention Center, Room 6F)

ECHELON-2 is a global, randomized, double-blind, multi-center trial evaluating ADCETRIS as part of a frontline combination chemotherapy regimen in patients with previously untreated CD30-expressing PTCL. The primary endpoint is PFS per Blinded Independent Central Review (BICR), with events defined as progression, death, or receipt of chemotherapy for residual or progressive disease. Key secondary endpoints include PFS in patients with sALCL, complete remission (CR) rate, OS and objective response rate (ORR). ECHELON-2 enrolled 452 patients (226 in each arm) at 132 sites in 17 countries across North America, Europe, Asia Pacific and the Middle East. The median age of patients was 58 years. The study enrolled patients with advanced disease (80 percent) and most patients had sALCL (48 percent ALK-negative and 22 percent ALK-positive).

Key findings, which will be presented by Dr. Steven Horwitz and published in The Lancet, include:

The ECHELON-2 study met its primary endpoint with ADCETRIS plus CHP demonstrating a statistically significant improvement in PFS as assessed by a BICR (hazard ratio [HR]=0.71; p-value=0.0110). This corresponds to a 29 percent reduction in the risk of progression, death or need for additional anticancer therapy for residual or progressive disease.
After a median follow-up time of 36.2 months, the median PFS in the ADCETRIS plus CHP arm was 48.2 months (95% CI, 35.2-not evaluable) compared to 20.8 months (95% CI, 12.7-47.6) in the control arm per BICR assessment. The three-year PFS was 57.1 percent for ADCETRIS plus CHP compared to 44.4 percent in the control arm.
Per investigator assessment, ADCETRIS plus CHP demonstrated a statistically significant improvement in PFS (HR=0.70; p-value=0.0096).
OS in the ADCETRIS plus CHP arm was statistically significant compared to CHOP (HR=0.66; p-value=0.0244). This corresponds to a 34 percent reduction in the risk of death.
After a median follow-up of 42.1 months, the median OS was not reached for either arm of the study. The estimated three-year OS was 76.8 percent for ADCETRIS plus CHP compared to 69.1 percent for CHOP.
All other key secondary endpoints, including CR rate and ORR, in addition to PFS in patients with sALCL, were statistically significant in favor of the ADCETRIS plus CHP arm. Per BICR assessment, the CR rate (68 percent versus 56 percent, respectively) and ORR (83 percent versus 72 percent, respectively) for the ADCETRIS plus CHP arm were significantly higher than those treated with CHOP (p-value=0.0066 and p-value=0.0032, respectively). Per investigator assessment, the CR rate and ORR showed a similar benefit for the ADCETRIS plus CHP arm versus CHOP (p-value=0.0043 and p-value=0.0018, respectively).
Excluding consolidative stem cell transplant or radiotherapy for consolidation of response to initial therapy, 74 percent of patients in the ADCETRIS plus CHP arm versus 58 percent of patients in the CHOP arm did not require subsequent anticancer therapies for residual or progressive disease. Of the 226 patients who received CHOP, 49 patients (22 percent) received subsequent treatment with an ADCETRIS-containing therapy.
The safety profile of ADCETRIS plus CHP in the ECHELON-2 trial was comparable to CHOP and consistent with the established safety profile of ADCETRIS in combination with chemotherapy.
The most common treatment-related adverse events of any grade occurring in 20 percent or more of patients in the ADCETRIS plus CHP and CHOP arm were: nausea (46 and 38 percent, respectively), peripheral sensory neuropathy (45 and 41 percent, respectively), neutropenia (38 percent each), diarrhea (38 and 20 percent, respectively), constipation (29 and 30 percent, respectively), alopecia (26 and 25 percent, respectively), pyrexia (26 and 19 percent, respectively), vomiting (26 and 17 percent, respectively), fatigue (24 and 20 percent, respectively) and anaemia (21 and 16 percent, respectively).
The most common Grade 3 or higher adverse events occurring in the ADCETRIS plus CHP and CHOP arms were neutropenia (35 and 34 percent, respectively) and anaemia (13 and 10 percent, respectively).
The incidence and severity of neutropenia was similar between study arms, and lower in the subset of patients who received primary prophylaxis with granulocyte-colony stimulating factor. Febrile neutropenia was reported in 41 patients (18 percent) in the ADCETRIS plus CHP arm and 33 patients (15 percent) in the CHOP arm.
New or worsening treatment-emergent peripheral neuropathy events occurred in 117 patients (52 percent) in the ADCETRIS plus CHP arm and 124 patients (55 percent) in the CHOP arm, with a majority at a maximum severity of Grade 1 (64 and 71 percent, respectively). At last follow-up, peripheral neuropathy returned to baseline or lower in 50 percent of the patients in the ADCETRIS plus CHP arm versus 64 percent in the CHOP arm, and the median time to resolution was 17 weeks and 11.4 weeks, respectively.
Adverse events leading to death occurred in seven patients (three percent) in the ADCETRIS plus CHP arm and nine patients (four percent) in the CHOP arm.

About T-Cell Lymphomas

Lymphoma is a general term for a group of cancers that originate in the lymphatic system. There are two major categories of lymphoma: Hodgkin lymphoma and non-Hodgkin lymphoma. There are more than 60 subtypes of non-Hodgkin lymphomas which are broadly divided into two major groups: B-cell lymphomas, which develop from abnormal B-lymphocytes, and T-cell lymphomas, which develop from abnormal T-lymphocytes. There are many different forms of T-cell lymphomas, some of which are extremely rare. T-cell lymphomas can be aggressive (fast-growing) or indolent (slow-growing). PTCL accounts for approximately 10 percent of non-Hodgkin lymphoma cases in the U.S. and Europe and may be as high as 24 percent in parts of Asia.

About ADCETRIS (brentuximab vedotin)

ADCETRIS is being evaluated broadly in more than 70 clinical trials in CD30-expressing lymphomas. These include the completed phase 3 ECHELON-2 trial in frontline peripheral T-cell lymphomas (also known as mature T-cell lymphoma), the completed phase 3 ECHELON-1 trial in previously untreated Hodgkin lymphoma, the completed phase 3 ALCANZA trial in cutaneous T-cell lymphoma.

ADCETRIS is an ADC comprising an anti-CD30 monoclonal antibody attached by a protease-cleavable linker to a microtubule disrupting agent, monomethyl auristatin E (MMAE), utilizing Seattle Genetics’ proprietary technology. The ADC employs a linker system that is designed to be stable in the bloodstream but to release MMAE upon internalization into CD30-expressing tumor cells.

ADCETRIS injection for intravenous infusion has received FDA approval for six indications in adult patients with: (1) previously untreated systemic anaplastic large cell lymphoma (sALCL) or other CD30-expressing peripheral T-cell lymphomas (PTCL), including angioimmunoblastic T-cell lymphoma and PTCL not otherwise specified, in combination with cyclophosphamide, doxorubicin, and prednisone, (2) previously untreated Stage III or IV classical Hodgkin lymphoma (cHL), in combination with doxorubicin, vinblastine, and dacarbazine, (3) cHL at high risk of relapse or progression as post-autologous hematopoietic stem cell transplantation (auto-HSCT) consolidation, (4) cHL after failure of auto-HSCT or failure of at least two prior multi-agent chemotherapy regimens in patients who are not auto-HSCT candidates, (5) sALCL after failure of at least one prior multi-agent chemotherapy regimen, and (6) primary cutaneous anaplastic large cell lymphoma (pcALCL) or CD30-expressing mycosis fungoides (MF) who have received prior systemic therapy.

Health Canada granted ADCETRIS approval with conditions for relapsed or refractory Hodgkin lymphoma and sALCL in 2013, and non-conditional approval for post-autologous stem cell transplantation (ASCT) consolidation treatment of Hodgkin lymphoma patients at increased risk of relapse or progression.

ADCETRIS received conditional marketing authorization from the European Commission in October 2012. The approved indications in Europe are: (1) for the treatment of adult patients with relapsed or refractory CD30-positive Hodgkin lymphoma following ASCT, or following at least two prior therapies when ASCT or multi-agent chemotherapy is not a treatment option, (2) the treatment of adult patients with relapsed or refractory sALCL, (3) for the treatment of adult patients with CD30-positive Hodgkin lymphoma at increased risk of relapse or progression following ASCT, and (4) for the treatment of adult patients with CD30-positive cutaneous T-cell lymphoma (CTCL) after at least one prior systemic therapy.

ADCETRIS has received marketing authorization by regulatory authorities in 72 countries for relapsed or refractory Hodgkin lymphoma and sALCL. See select important safety information, including Boxed Warning, below.

Seattle Genetics and Takeda are jointly developing ADCETRIS. Under the terms of the collaboration agreement, Seattle Genetics has U.S. and Canadian commercialization rights and Takeda has rights to commercialize ADCETRIS in the rest of the world. Seattle Genetics and Takeda are funding joint development costs for ADCETRIS on a 50:50 basis, except in Japan where Takeda is solely responsible for development costs.

On December 3, 2018 Kite, a Gilead Company (Nasdaq: GILD), reported its updated results from ZUMA-3, a single-arm Phase 1/2 study evaluating KTE-X19 (formerly KTE-C19), an investigational CD19 chimeric antigen receptor T (CAR T) cell therapy, in adult patients with relapsed or refractory acute lymphoblastic leukemia (ALL) (Press release, Kite Pharma, DEC 3, 2018, View Source [SID1234531849]). With a median follow-up of 15.1 months (range 3.7 – 28.6 months) following a single infusion of KTE-X19, 69 percent of evaluable patients (n=25/36) achieved complete tumor remission, defined as complete remission (CR) or CR with incomplete hematological recovery (CRi). The rate of undetectable minimal residual disease (MRD) in patients who achieved complete tumor remission was 100 percent. Detailed results from this ongoing study were presented today at the Annual Meeting of the American Society of Hematology (ASH) (Free ASH Whitepaper) (ASH; Abstract #897).

"We are encouraged by the high number of patients who achieved complete leukemia remission following a single KTE-X19 infusion on this trial," said William G. Wierda, MD, PhD, Executive Medical Director and Professor, Department of Leukemia, Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center. "In relapsed and refractory ALL, where the majority of adult patients have poor response to treatment and short remissions and survival, these findings give optimism for improving outcomes and potentially showing clinical benefit for those affected by ALL."

Adverse events were consistent with the known toxicities of CD19 CAR T treatment, including Grade 3 or higher cytokine release syndrome (CRS) and neurologic events in 23 percent (n=10/44) and 39 percent (n=17/44) of patients, respectively. The majority of these adverse events were resolved, with the exception of two patients who had ongoing neurological events at the time of death from other causes. Two patients died from adverse events deemed by the treating investigator to be related to KTE-X19.

"These updated results from ZUMA-3 provide continued support for the potential of our CD19-directed CAR T therapies in new types of cancers and reinforce our leadership in cell therapy," said Alessandro Riva, MD, Executive Vice President, Oncology Therapeutics and Head, Cell Therapy, Gilead Sciences. "Based on these findings, we have initiated Phase 2 of the study evaluating KTE-X19 in a larger set of adult patients with ALL who are in need of new treatment options."

KTE-X19 is an investigational agent that has not been approved for any uses. Efficacy and safety have not been established.

About ALL

ALL is an aggressive type of blood cancer which can also involve the lymph nodes, spleen, liver, central nervous system and other organs.

About ZUMA-3

ZUMA-3 is an ongoing multicenter, registrational Phase 1/2 study in adult patients (≥18) with ALL whose disease is refractory to or has relapsed following standard chemotherapy or hematopoietic stem cell transplantation. The objectives of the study are to evaluate the safety and efficacy of KTE-X19 in this patient population.

On December 3, 2018 Celgene Corporation (NASDAQ:CELG) reported initial safety data from its ongoing proof-of-concept trial of JCARH125 in patients with relapsed/refractory multiple myeloma. JCARH125 is an investigational BCMA-targeting CAR T cell therapy being developed by Juno Therapeutics, A Celgene Company (Press release, Celgene, DEC 3, 2018, View Source [SID1234531848]). Results were presented by Sham Mailankody, MBBS, in an oral presentation at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition in San Diego, CA (Abstract #957).

The data reported from the multicenter, phase 1/2 EVOLVE trial includes patients who have been treated with JCARH125 in the dose escalation study. The primary objectives of the phase 1 portion of the trial are safety and identification of a recommended phase 2 dose. The patients enrolled in the study had to have received at least three prior lines of multiple myeloma therapy, including an autologous stem cell transplant for transplant eligible patients, a proteasome inhibitor, an immunomodulatory drug, and an anti-CD38 monoclonal antibody. Dose escalation is currently ongoing.

"We believe that cellular therapies targeting BCMA will play an important role in the future treatment of patients with multiple myeloma," said Mark Gilbert, M.D., Chief Medical Officer for Juno Therapeutics, A Celgene Company. "These data from 44 patients in the EVOLVE trial further support our commitment to innovation in multiple myeloma clinical research."

At data cut off, 44 patients have been infused with JCARH125 in three dose escalation cohorts. These patients were heavily pretreated, with a median of seven prior lines of therapies (range, 3-23), and 77% had high-risk cytogenetics. Seventy-one percent of patients experienced grade 1 and 2 cytokine release syndrome (CRS) with 9% of patients experiencing grade 3/4 CRS. In addition, 18% of patients experienced grade 1 and 2 neurological events with 7% of patients experiencing a grade 3/4 event. Other frequent grade 3/4 AEs included neutropenia (86%), anemia (50%), thrombocytopenia (43%) and infection (14%).

In this first report of JCARH125 data, the median follow up was only 11 weeks, yet among infused patients, the overall response rate (ORR) was 82%. At the lowest dose level of 50×106 CAR T cells, the ORR was 79% and 43% of patients achieved stringent complete response (sCR) or complete response (CR).

JCARH125 is investigational and has not been approved in any country

On December 3, 2018 Verastem, Inc. (Nasdaq:VSTM) (Verastem Oncology or the Company), focused on developing and commercializing medicines to improve the survival and quality of life of cancer patients, reported an oral presentation highlighting new clinical data from an investigator sponsored trial, led by Steven Horwitz, MD, Memorial Sloan Kettering Cancer Center (MSK), evaluating duvelisib in combination with romidepsin in patients with relapsed or refractory T-cell lymphomas, including peripheral T-cell lymphoma (PTCL) and cutaneous T-cell lymphoma (CTCL) at the American Society of Hematology (ASH) (Free ASH Whitepaper) 2018 Annual Meeting, taking place December 1-4, 2018, in San Diego (Press release, Verastem, DEC 3, 2018, View Source [SID1234531847]). Duvelisib is an oral inhibitor of phosphoinositide 3-kinase (PI3K), and the first approved dual inhibitor of PI3K-delta and PI3K-gamma.

"The data demonstrate that the combination of oral duvelisib and romidepsin has an acceptable safety profile and the presence of early signals of anti-lymphoma activity in patients with PTCL," said Steven Horwitz, MD, Memorial Sloan Kettering Cancer Center (MSK), co-principal investigator of the Phase 1 study, and lead author of the oral presentation. "The response rate observed to date from the combination is compelling considering that PTCL is an aggressive type of non-Hodgkin lymphoma for which new therapies are desperately needed. We look forward to further elucidating the potential of this novel combination regimen through completion of this expansion cohort."

Phase 1 Results with Duvelisib and Romidepsin in Relapsed or Refractory PTCL

In this multicenter, dose-expansion portion of the Phase 1 trial, oral duvelisib was dosed at 75mg twice-daily (BID) on days 1-28. Romidepsin 10mg/m2 was dosed on Days 1, 8, and 15 on a 28-day cycle. Of the 38 patients evaluable for efficacy (PTCL, n=27; CTCL, n=11), 21 responded (9 complete responses (CRs) and 12 partial responses (PRs)) for an overall response rate (ORR) of 55%. Sixteen of the 27 patients with PTCL responded (9 CRs and 7 PRs) for an ORR of 59%. Five of the 11 patients with CTCL responded (all PRs) for an ORR of 45%. Median progression-free survival (PFS) for patients with PTCL was 6.72 months and 5.41 months for patients with CTCL. Among the 39 patients evaluable for safety, the most common Grade ≥3 adverse events were neutropenia (33%), diarrhea (15%) and increased alanine aminotransferase (13%).

A PDF copy of the oral presentation will be available here following the conclusion of the session.

Verastem Oncology is currently conducting an open-label, multicenter, Phase 2 clinical trial (the PRIMO study; NCT03372057) evaluating the efficacy and safety of duvelisib monotherapy in adult patients with histologically confirmed relapsed or refractory PTCL. This study is expected to enroll approximately 120 patients.

In addition, Verastem Oncology’s PTCL program was recently selected to participate in The Leukemia and Lymphoma Society’s Therapy Acceleration Program which provides additional resources to support the development of therapies for patients with blood cancers. The program is supporting work on translational biomarkers of response, patient enrollment acceleration in PRIMO and an increase in the total patient enrollment in the combination study of duvelisib and romidepsin being presented at ASH (Free ASH Whitepaper).

About Peripheral T-Cell Lymphoma

Peripheral T-cell lymphoma (PTCL) is a rare, aggressive type of non-Hodgkin lymphoma (NHL) that develops in mature white blood cells called "T cells" and "natural killer (NK) cells"1 which circulate with the lymphatic system.2 PTCL accounts for between 10-15% of all non-Hodgkin lymphomas (NHLs) and generally affects people aged 60 years and older.1 Although there are many different subtypes of peripheral T-cell lymphoma, they often present in a similar way, with widespread, enlarged, painless lymph nodes in the neck, armpit or groin.2 There is currently no established standard of care for patients with relapsed or refractory disease.1

On December 3, 2018 Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), reported new data from the Venclexta (venetoclax) clinical development program, including longer-term results from the Phase III MURANO study in people with previously treated chronic lymphocytic leukemia (CLL) and updated data from two Phase Ib/II studies in people with previously untreated acute myeloid leukemia (AML) ineligible for intensive chemotherapy due to coexisting medical conditions (Press release, Genentech, DEC 3, 2018, View Source [SID1234531846]). Data from the Venclexta clinical development program that ranges across multiple blood cancers, including CLL, AML, non-Hodgkin’s lymphoma and multiple myeloma, will be featured in more than 30 abstracts, including 12 oral presentations, at the 60th American Society of Hematology (ASH) (Free ASH Whitepaper) 2018 Annual Meeting.

"We’re excited by the versatility of Venclexta in treating a range of distinct types of blood cancer, including difficult-to-treat forms with limited options," said Sandra Horning, M.D., chief medical officer and head of Global Product Development. "These data support our broad clinical development program through which we hope to discover more ways Venclexta can be used alone or in combination with other medicines to treat additional types of cancer."

Updated Data in CLL

Two new analyses of the Phase III MURANO study in relapsed or refractory (R/R) CLL demonstrated the continued clinical benefit of Venclexta plus Rituxan (rituximab) was sustained after patients completed the chemotherapy-free, two-year fixed-duration course of therapy.

An analysis showed the combination reduced the risk of disease progression or death (progression-free survival; PFS, as assessed by investigator) by 84 percent (HR=0.16; 95 percent CI: 0.12-0.23; p<0.0001) compared to standard of care bendamustine plus Rituxan (BR) after a median three-year follow-up. At three years, 71 percent of patients in the Venclexta plus Rituxan arm had not experienced disease progression, compared to 15 percent of patients in the BR arm (median PFS: not reached vs. 17.0 months, respectively). A clinically meaningful benefit in overall survival was also observed in the Venclexta arm compared to the BR arm (88 percent vs. 80 percent, HR=0.50; 95 percent CI: 0.30-0.85). Consistent benefit was observed in all patient subgroups for Venclexta plus Rituxan compared to BR, including high-risk and low-risk groups. Data were presented in an oral session on Saturday, December 1, at 2:45 P.M. PST (Abstract #184).
A separate analysis showed higher rates of minimal residual disease (MRD)-negativity observed with Venclexta plus Rituxan compared to BR were sustained after patients completed treatment (62 percent vs. 13 percent). MRD-negativity means no cancer can be detected using a specific, highly sensitive test, and was defined as less than 1 CLL cell in 10,000 leukocytes. Importantly, these results were observed in the majority of patients in the Venclexta arm, including patients in high-risk subgroups and were consistent with the maintained PFS benefit seen with longer follow-up. These data support the utility of MRD in peripheral blood as a predictive marker of clinical outcome. No new safety signals were observed with the treatment combination of Venclexta plus Rituxan. These data will be presented in an oral session on Monday, December 3, at 11:30 A.M. PST (Abstract #695).
Updated Data in AML

Updated data from the Phase Ib M14-358 and Phase I/II M14-387 studies evaluating Venclexta in combination with a hypomethylating agent or low-dose cytarabine (LDAC) in people with previously untreated AML who are ineligible for intensive chemotherapy will also be presented. These results showed that among patients who were dependent upon blood transfusions at baseline, about half were able to achieve transfusion independence (the absence of transfusions during any consecutive 56 days during the study treatment period). No unexpected safety signals were observed with Venclexta in combination with hypomethylating agents or LDAC.

The M14-358 study showed high rates of complete remission (with at least partial blood count recovery, CR+CRh) of 67 percent for those who received Venclexta plus azacitidine and 71 percent for those who received Venclexta plus decitabine. For people taking Venclexta and azacitadine or decitabine who were dependent on blood transfusions at baseline, 50 percent and 52 percent achieved red blood cell transfusion independence, respectively; and 58 percent or 60 percent achieved platelet transfusion independence, respectively.
The M14-387 study showed rates of complete remission (with or without full recovery of normal blood cell count, CR+CRi) of 54 percent in people who received Venclexta in combination with LDAC and a median duration of remission of 8.1 months. For people taking Venclexta with LDAC, 48 percent achieved red blood cell transfusion independence and 60 percent achieved platelet transfusion independence.
Results from the two studies were presented in an oral session on Sunday, December 2 at 7:45 A.M. PST and 8:00 A.M. PST, respectively (Abstract #284 and #285).

Based on earlier results from the M14-358 and M14-387 studies, Venclexta was granted accelerated approval by the U.S. Food and Drug Administration (FDA) for the treatment of people with newly-diagnosed AML who are age 75 years or older, or for those ineligible for intensive induction chemotherapy due to coexisting medical conditions. A robust clinical development program for Venclexta in AML is ongoing, including two ongoing Phase III studies evaluating Venclexta in combination with azacitidine or with LDAC for people with previously untreated AML who are ineligible for intensive chemotherapy based on results from the M14-358 and M14-387 studies.

Venclexta is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the U.S. and commercialized by AbbVie outside of the U.S.

About the MURANO study

MURANO (NCT02005471) is a Phase III open-label, international, multicenter, randomized study evaluating the efficacy and safety of Venclexta in combination with Rituxan compared to bendamustine in combination with Rituxan (BR). All treatments were of fixed duration. Following a five-week dose ramp-up schedule for Venclexta, patients on the Venclexta plus Rituxan arm received six cycles of Venclexta plus Rituxan followed by Venclexta monotherapy for up to two years total. Patients on the BR arm received six cycles of BR. The study included 389 patients with chronic lymphocytic leukemia (CLL) who had been previously treated with at least one line of therapy. Patients were randomly assigned in a 1:1 ratio to receive either Venclexta plus Rituxan or BR. The primary endpoint of the study was progression-free survival (PFS). Secondary endpoints included overall survival (OS), overall response rate (ORR) and complete response rate (with or without complete blood count recovery, CR/CRi).

About the M14-358 study

The M14-358 study (NCT02203773) is an open-label, non-randomized, Phase Ib dose escalation and expansion study evaluating the safety and efficacy of Venclexta in combination with hypomethylating agents, azacitidine or decitabine, in 115 newly-diagnosed people with AML who were 60 years or older, or ineligible to receive intensive induction chemotherapy due to coexisting medical conditions. Study endpoints included complete remission rates, transfusion independence, overall survival and safety.

About the M14-387 study

The M14-387 study (NCT02287233) is an open-label, single-arm, Phase I/II dose escalation and expansion study evaluating the safety and efficacy of Venclexta in combination with LDAC in 82 newly-diagnosed people with AML who were 60 years or older, or ineligible to receive intensive induction chemotherapy due to coexisting medical conditions. Study endpoints included complete remission rates, transfusion independence, overall survival and safety.

About CLL

Chronic lymphocytic leukemia (CLL) is the most common type of adult leukemia, and in 2018, it is estimated there will be more than 20,000 new cases of CLL diagnosed in the United States. Although signs of CLL may disappear for a period of time after initial treatment, the disease is considered incurable and many people will require additional treatment due to the return of cancerous cells.

About AML

Acute myeloid leukemia (AML) is the most common type of aggressive leukemia in adults, which has the lowest survival rate for all types of leukemia. In 2018, it is estimated there will be nearly 20,000 new cases of AML diagnosed in the United States. Many AML patients older than age 60 are unable to tolerate standard intensive chemotherapy treatment.

About Venclexta

Venclexta is a first-in-class targeted medicine designed to selectively bind and inhibit the B-cell lymphoma-2 (BCL-2) protein. In some blood cancers and other tumors, BCL-2 builds up and prevents cancer cells from dying or self-destructing, a process called apoptosis. Venclexta blocks the BCL-2 protein and works to restore the process of apoptosis.

Venclexta is being developed by AbbVie and Genentech, a member of the Roche Group. It is jointly commercialized by the companies in the U.S. and commercialized by AbbVie outside of the U.S. Together, the companies are committed to research with Venclexta, which is currently being studied in clinical trials across several types of blood and other cancers.

In the U.S., Venclexta has been granted four Breakthrough Therapy Designations by the FDA: in combination with Rituxan for people with relapsed or refractory chronic lymphocytic leukemia (CLL); as a monotherapy for people with relapsed or refractory CLL with 17p deletion; in combination with hypomethylating agents (azacitidine or decitabine) for people with untreated acute myeloid leukemia (AML) ineligible for intensive chemotherapy; and in combination with low-dose cytarabine for people with untreated AML ineligible for intensive chemotherapy.

Venclexta Indications

Venclexta is a prescription medicine used:

To treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), with or without 17p deletion, who have received at least 1 prior treatment.
In combination with azacitidine, or decitabine, or low-dose cytarabine to treat adults with newly-diagnosed acute myeloid leukemia (AML) who:
‒ Are 75 years of age or older, or

‒ Have other medical conditions that prevent the use of standard chemotherapy.

It is not known if Venclexta is safe and effective in children.

Important Safety Information

Venclexta can cause serious side effects, including:

Tumor lysis syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure, the need for dialysis treatment, and may lead to death. The patient’s doctor will do tests to check their risk of getting TLS before they start taking Venclexta. The patient will receive other medicines before starting and during treatment with Venclexta to help reduce the risk of TLS. The patient may also need to receive intravenous (IV) fluids through their vein.

The patient’s doctor will do blood tests to check for TLS when the patient first starts treatment and during treatment with Venclexta. It is important for patients to keep appointments for blood tests. Patients should tell their doctor right away if they have any symptoms of TLS during treatment with Venclexta, including fever, chills, nausea, vomiting, confusion, shortness of breath, seizures, irregular heartbeat, dark or cloudy urine, unusual tiredness, or muscle or joint pain.

Patients should drink plenty of water during treatment with Venclexta to help reduce the risk of getting TLS.

Patients should drink 6 to 8 glasses (about 56 ounces total) of water each day, starting 2 days before the first dose, on the day of the first dose of Venclexta, and each time a dose is increased.

The patient’s doctor may delay, decrease the dose, or stop treatment with Venclexta if the patient has side effects.

Certain medicines must not be taken when the patient first starts taking Venclexta and while the dose is being slowly increased because of the risk of increased tumor lysis syndrome.

Patients must tell their doctor about all the medicines they take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Venclexta and other medicines may affect each other, causing serious side effects.
Patients must not start new medicines during treatment with Venclexta without first talking with their doctor.
Before taking Venclexta, patients must tell their doctor about all of their medical conditions, including if they:

Have kidney problems.
Have problems with body salts or electrolytes, such as potassium, phosphorus, or calcium.
Have a history of high uric acid levels in the blood or gout.
Are scheduled to receive a vaccine. The patient should not receive a "live vaccine" before, during, or after treatment with Venclexta, until the patient’s doctor tells them it is okay. If the patient is not sure about the type of immunization or vaccine, the patient should ask their doctor. These vaccines may not be safe or may not work as well during treatment with Venclexta.
Are pregnant or plan to become pregnant. Venclexta may harm an unborn baby. If the patient is able to become pregnant, the patient’s doctor should do a pregnancy test before the patient starts treatment with Venclexta, and the patient should use effective birth control during treatment and for at least 30 days after the last dose of Venclexta. If the patient becomes pregnant or thinks they are pregnant, the patient should tell their doctor right away.
Are breastfeeding or plan to breastfeed. It is not known if Venclexta passes into the patient’s breast milk. Patients should not breastfeed during treatment with Venclexta.
What to avoid while taking Venclexta:

Patients should not drink grapefruit juice, eat grapefruit, Seville oranges (often used in marmalades), or starfruit while they are taking Venclexta. These products may increase the amount of Venclexta in the patient’s blood.

Venclexta can cause serious side effects, including:

Low white blood cell counts (neutropenia). Low white blood cell counts are common with Venclexta, but can also be severe. The patient’s doctor will do blood tests to check their blood counts during treatment with Venclexta. Patients should tell their doctor right away if they have a fever or any signs of an infection during treatment with Venclexta.
The most common side effects of Venclexta when used in combination with rituximab in people with CLL include low white blood cell counts; diarrhea; upper respiratory tract infection; cough; tiredness; and nausea.

The most common side effects of Venclexta when used alone in people with CLL/SLL include low white blood cell counts; diarrhea; nausea; upper respiratory tract infection; low red blood cell counts; tiredness; low platelet counts; muscle and joint pain; swelling of arms, legs, hands, and feet; and cough.

The most common side effects of Venclexta in combination with azacitidine, or decitabine, or low-dose cytarabine in people with AML include low white blood cell counts; nausea; diarrhea; low platelet counts; constipation; fever with low white blood cell counts; low red blood cell counts; infection in blood; rash; dizziness; low blood pressure; fever; swelling of arms, legs, hands, and feet; vomiting; tiredness; shortness of breath; bleeding; infection in lung; stomach (abdominal) pain; pain in muscles or back; cough; and sore throat.

Venclexta may cause fertility problems in males. This may affect the ability to father a child. Patients should talk to their doctor if they have concerns about fertility.

These are not all the possible side effects of Venclexta. Patients should tell their doctor about any side effect that bothers them or that does not go away.

Blisters
Peeling skin
Rash
Pustules
Hepatitis B Virus (HBV) Reactivation: Before receiving Rituxan treatment, the patient’s doctor will do blood tests to check for HBV infection. If the patient has had hepatitis B or is a carrier of hepatitis B virus, receiving Rituxan could cause the virus to become an active infection again. Hepatitis B reactivation may cause serious liver problems, including liver failure, and death. The patient’s doctor will monitor for hepatitis B infection during and for several months after the patient stops receiving Rituxan.

Patients must tell their doctor right away about worsening tiredness, or yellowing of the skin or white part of the eyes during treatment with Rituxan.
Progressive Multifocal Leukoencephalopathy (PML): PML is a rare, serious brain infection caused by a virus that can happen in people who receive Rituxan. People with weakened immune systems can get PML. PML can result in death or severe disability. There is no known treatment, prevention, or cure for PML.

Patients must tell their doctor right away about new or worsening symptoms or if anyone close to the patient notices these symptoms:
Confusion
Dizziness or loss of balance
Difficulty walking or talking
Decreased strength or weakness on one side of the body
Vision problems, such as blurred vision or loss of vision

Are taking any medications, including prescription and over-the-counter medicines, vitamins, and herbal supplements
What are the possible side effects of Rituxan?

Rituxan can cause serious side effects, including:

Tumor Lysis Syndrome (TLS): TLS is caused by the fast breakdown of cancer cells. TLS can cause the patient to have:
Kidney failure and the need for dialysis treatment
Abnormal heart rhythm
TLS can happen within 12 to 24 hours after an infusion of Rituxan. The patient’s doctor may do blood tests to check for TLS. The patient’s doctor may give medicine to help prevent TLS. Patients must tell their doctor right away if they have any of the following signs or symptoms of TLS:
Nausea
Vomiting
Diarrhea
Lack of energy
Serious Infections: Serious infections can happen during and after treatment with Rituxan, and can lead to death. Rituxan can increase the patient’s risk of getting infections and can lower the ability of the patient’s immune system to fight infections. Types of serious infections that can happen with Rituxan include bacterial, fungal, and viral infections. After receiving Rituxan, some people have developed low levels of certain antibodies in their blood for a long period of time (longer than 11 months). Some of these patients with low antibody levels developed infections. People with serious infections should not receive Rituxan. Patients must tell their doctor right away if they have any symptoms of infection:
Fever
Cold symptoms, such as runny nose or sore throat that do not go away
Flu symptoms, such as cough, tiredness, and body aches
Earache or headache
Pain during urination
Cold sores in the mouth or throat
Cuts, scrapes, or incisions that are red, warm, swollen, or painful
Heart Problems: Rituxan may cause chest pain, irregular heartbeats, and heart attack. The patient’s doctor may monitor the patient’s heart during and after treatment with Rituxan if they have symptoms of heart problems or have a history of heart problems. Patients must tell their doctor right away if they have chest pain or irregular heart-beats during treatment with Rituxan.
Kidney Problems: especially if the patient is receiving Rituxan for non-Hodgkin’s lymphoma. Rituxan can cause severe kidney problems that lead to death. The patient’s doctor should do blood tests to check how well their kidneys are working.
Stomach and Serious Bowel Problems That Can Sometimes Lead to Death: Bowel problems, including blockage or tears in the bowel can happen if the patient receives Rituxan with chemotherapy medicines. Patients must tell their doctor right away if they have any stomach-area (abdomen) pain or repeated vomiting during treatment with Rituxan.
