On December 12, 2017 Janssen Research & Development, LLC reported data from the Phase 3 ALCYONE study, showing that DARZALEX (daratumumab) in combination with bortezomib, melphalan and prednisone (VMP) significantly improved clinical outcomes, including reducing the risk of disease progression or death by 50 percent, in patients with newly diagnosed multiple myeloma who are ineligible for autologous stem cell transplantation (ASCT) (Press release, Johnson & Johnson, DEC 12, 2017, View Source [SID1234522596]). These data were presented as a late-breaking abstract today at the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in Atlanta (Abstract #LBA-4). Study findings were simultaneously published in the New England Journal of Medicine.

"These Phase 3 results for DARZALEX demonstrated clinically meaningful improvements with a manageable safety profile," said Dr. Maria-Victoria Mateos, Ph.D., lead ALCYONE study investigator and Director of the Myeloma Unit at University Hospital of Salamanca-IBSAL, Salamanca, Spain. "Selecting the right treatment regimen is critical for patients who are newly diagnosed, especially if they are transplant ineligible, as these patients tend to be older and more frail. These findings strongly support this DARZALEX frontline regimen as a new standard of care for these patients."

At a median follow-up of 16.5 months, DARZALEX-VMP reduced the risk of disease progression or death by 50 percent, compared to treatment with VMP alone (Hazard Ratio [HR] = 0.50; 95 percent CI [0.38-0.65], p<0.0001).1 The median progression-free survival (PFS) for DARZALEX-VMP had not yet been reached, compared to an estimated median PFS of 18.1 months for patients who received VMP alone.1

In addition to reducing the risk of disease progression or death, DARZALEX significantly improved overall response rates (ORR) (91 percent vs. 74 percent) compared to VMP alone, including more than doubling rates of stringent complete response (sCR) (18 percent vs. 7 percent) and significantly improving rates of very good partial response (VGPR) or better (71 percent vs. 50 percent) and complete response (CR) or better (43 percent vs. 24 percent).1 Patients receiving DARZALEX also reported a more than three-fold increase in the minimal residual disease (MRD) negativity rate (22 percent vs. 6 percent) compared to those who received VMP alone.1

The most common (≥10 percent) Grade 3/4 treatment-emergent adverse events (TEAEs) for DARZALEX-VMP vs. VMP were neutropenia (40 percent vs. 39 percent), thrombocytopenia (34 percent vs. 38 percent), anemia (16 percent vs. 20 percent) and pneumonia (11 percent vs. 4 percent).1 One patient in each arm discontinued treatment due to pneumonia, and 0.9 percent of patients discontinued DARZALEX due to an infection.1 Twenty-eight percent of patients experienced infusion reactions (IRs) due to DARZALEX.1 In the DARZALEX-VMP arm, 42 percent of patients experienced a serious adverse event (SAE), compared to 33 percent in the VMP arm.1 The most common (≥2 percent) SAEs were pneumonia (10 percent vs. 3 percent), anemia (2 percent vs. 3 percent), bronchitis (2 percent vs. 1 percent), lower respiratory tract infection (2 percent vs. 1 percent), upper respiratory tract infection (2 percent vs. 1 percent), febrile neutropenia (1 percent vs. 2 percent) and cardiac failure (<1 percent vs. 2 percent) for DARZALEX-VMP vs. VMP, respectively.1

"DARZALEX offers compelling and consistent clinical benefit across all lines of therapy in multiple myeloma," said Sen Zhuang, M.D. Ph.D., Vice President, Oncology Clinical Research, Janssen Research & Development. "These latest results convey the promise of DARZALEX in newly diagnosed patients for whom the initial therapy is most critical for long-term survival."

On November 21, 2017, Janssen submitted a supplemental Biologics License Application (sBLA) to the U.S. Food and Drug Administration (FDA) for DARZALEX in combination with VMP for this patient population. Janssen requested Priority Review of this sBLA, which would shorten FDA review to six months, compared to 10 months for Standard Review. If approved, this would be the fifth indication for DARZALEX in the U.S. and its first in the frontline setting. On November 21, 2017, Janssen also submitted an application for this patient population to the European Medicines Agency.

About the ALCYONE Trial1
The randomized, open-label, multicenter Phase 3 ALCYONE (MMY3007) study enrolled 706 newly diagnosed patients with multiple myeloma who were ineligible for high-dose chemotherapy with ASCT. In the DARZALEX-VMP arm, the median age was 71 years (range: 40-93), 30 percent were ≥75 years and 46 percent were male. Patients were randomized to receive nine cycles of either DARZALEX combined with VMP, or VMP alone. In the DARZALEX-VMP arm, patients received 16 mg/kg of DARZALEX once weekly for six weeks (Cycle 1; 1 Cycle = 42 days), followed by once every three weeks (Cycles 2-9). Following the nine cycles, patients in the DARZALEX-VMP arm continued to receive 16 mg/kg of DARZALEX once every four weeks until disease progression.

About DARZALEX (daratumumab) Injection, for Intravenous Infusion
DARZALEX (daratumumab) injection for intravenous use is the first CD38-directed antibody approved anywhere in the world.2 CD38 is a surface protein that is highly expressed across multiple myeloma cells.3 DARZALEX is believed to induce tumor cell death through multiple immune-mediated mechanisms of action, including complement-dependent cytotoxicity (CDC), antibody-dependent cell-mediated cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP), as well as through apoptosis, in which a series of molecular steps in a cell lead to its death.2 A subset of myeloid derived suppressor cells (MDSCs), CD38+ regulatory T cells (Tregs) and CD38+ B cells (Bregs) were decreased by DARZALEX.2 DARZALEX is being evaluated in a comprehensive clinical development program across a range of treatment settings in multiple myeloma, such as in frontline and relapsed settings.4,5,6,7,8 Additional studies are ongoing or planned to assess its potential for a solid tumor indication and in other malignant and pre-malignant diseases in which CD38 is expressed, such as smoldering myeloma.9,10,11 DARZALEX was the first CD38-directed antibody to receive regulatory approval to treat relapsed or refractory multiple myeloma.2

In August 2012, Janssen Biotech, Inc. and Genmab A/S entered a worldwide agreement, which granted Janssen an exclusive license to develop, manufacture and commercialize DARZALEX.12 DARZALEX is commercialized in the U.S. by Janssen Biotech, Inc.12 For more information, visit www.DARZALEX.com.

About Multiple Myeloma
Multiple myeloma is an incurable blood cancer that occurs when malignant plasma cells grow uncontrollably in the bone marrow.13,14 Refractory cancer occurs when a patient’s disease is resistant to treatment or in the case of multiple myeloma, patients progress within 60 days of their last therapy.15,16 Relapsed cancer means the disease has returned after a period of initial, partial or complete remission.17 It is estimated that 30,280 people will be diagnosed and 12,590 will die from the disease in the United States in 2017.18 While some patients with multiple myeloma have no symptoms at all, most patients are diagnosed due to symptoms, which can include bone fracture or pain, low red blood counts, fatigue, calcium elevation, kidney problems or infections.19

IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS – None
WARNINGS AND PRECAUTIONS
Infusion Reactions – DARZALEX can cause severe infusion reactions. Approximately half of all patients experienced a reaction, most during the first infusion. Infusion reactions can also occur with subsequent infusions. Nearly all reactions occurred during infusion or within 4 hours of completing an infusion. Prior to the introduction of post-infusion medication in clinical trials, infusion reactions occurred up to 48 hours after infusion. Severe reactions have occurred, including bronchospasm, hypoxia, dyspnea, hypertension, laryngeal edema and pulmonary edema. Signs and symptoms may include respiratory symptoms, such as nasal congestion, cough, throat irritation, as well as chills, vomiting and nausea. Less common symptoms were wheezing, allergic rhinitis, pyrexia, chest discomfort, pruritus, and hypotension.

Pre-medicate patients with antihistamines, antipyretics, and corticosteroids. Frequently monitor patients during the entire infusion. Interrupt infusion for reactions of any severity and institute medical management as needed. Permanently discontinue therapy for life-threatening (Grade 4) reactions. For patients with Grade 1, 2, or 3 reactions, reduce the infusion rate when re-starting the infusion.

To reduce the risk of delayed infusion reactions, administer oral corticosteroids to all patients following DARZALEX infusions. Patients with a history of chronic obstructive pulmonary disease may require additional post-infusion medications to manage respiratory complications. Consider prescribing short- and long-acting bronchodilators and inhaled corticosteroids for patients with chronic obstructive pulmonary disease.

Interference with Serological Testing – Daratumumab binds to CD38 on red blood cells (RBCs) and results in a positive Indirect Antiglobulin Test (Indirect Coombs test). Daratumumab-mediated positive indirect antiglobulin test may persist for up to 6 months after the last daratumumab infusion. Daratumumab bound to RBCs masks detection of antibodies to minor antigens in the patient’s serum. The determination of a patient’s ABO and Rh blood type are not impacted. Notify blood transfusion centers of this interference with serological testing and inform blood banks that a patient has received DARZALEX. Type and screen patients prior to starting DARZALEX.

Neutropenia – DARZALEX may increase neutropenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. Monitor patients with neutropenia for signs of infection. DARZALEX dose delay may be required to allow recovery of neutrophils. No dose reduction of DARZALEX is recommended. Consider supportive care with growth factors.

Thrombocytopenia – DARZALEX may increase thrombocytopenia induced by background therapy. Monitor complete blood cell counts periodically during treatment according to manufacturer’s prescribing information for background therapies. DARZALEX dose delay may be required to allow recovery of platelets. No dose reduction of DARZALEX is recommended. Consider supportive care with transfusions.

Interference with Determination of Complete Response – Daratumumab is a human IgG kappa monoclonal antibody that can be detected on both, the serum protein electrophoresis (SPE) and immunofixation (IFE) assays used for the clinical monitoring of endogenous M-protein. This interference can impact the determination of complete response and of disease progression in some patients with IgG kappa myeloma protein.

The overall incidence of serious adverse reactions was 42%. Serious adverse reactions were upper respiratory tract infection (5%), diarrhea (2%) and atrial fibrillation (2%).

In patients who received DARZALEX as monotherapy, the most frequently reported adverse reactions (incidence ≥20%) were: neutropenia (60%), thrombocytopenia (48%), infusion reactions (48%), fatigue (39%), nausea (27%), back pain (23%), pyrexia (21%), cough (21%), and upper respiratory tract infection (20%). Serious adverse reactions were reported in 51 (33%) patients. The most frequent serious adverse reactions were pneumonia (6%), general physical health deterioration (3%), and pyrexia (3%).

In patients who received DARZALEX in combination with pomalidomide and dexamethasone, the most frequent adverse reactions (>20%) were infusion reactions (50%), diarrhea (38%), constipation (33%), nausea (30%), vomiting (21%), fatigue (50%), pyrexia (25%), upper respiratory tract infection (50%), muscle spasms (26%), back pain (25%), arthralgia (22%), dizziness (21%), insomnia (23%), cough (43%) and dyspnea (33%). The overall incidence of serious adverse reactions was 49%. Serious adverse reactions reported in ≥5% patients included pneumonia (7%).

DRUG INTERACTIONS
Effect of Other Drugs on daratumumab: The coadministration of lenalidomide, pomalidomide or bortezomib with DARZALEX did not affect the pharmacokinetics of daratumumab.

Effect of Daratumumab on Other Drugs: The coadministration of DARZALEX with bortezomib did not affect the pharmacokinetics of bortezomib.

For patients with R/R AML treated at the Phase 2 dose (n = 54) and for whom median follow up was 6.6 months:

Clinical remission (CR+CRi) was 43%.
Median overall survival was 9.4 months (95% CI: 5.7 – 15.1 months; calculated by Kaplan Meier method). This compares favorably to a median overall survival of up to 5.4 months reported for historical, matched controls treated with mitoxantrone, etoposide and cytarabine (MEC) alone. 1,2
Median duration of remission was 11.1 months (95% CI: 5.8-NA; calculated by Kaplan Meier method).
For older patients with newly diagnosed disease (n=25) and for whom median follow up was 10.5 months:

Clinical remission rate was 68%.
Median overall survival was 15.8 months (95% CI: 10.3 – NA; calculated by Kaplan Meier method). This compares favorably to a historical median overall survival of approximately 12 months in matched controls treated with 7+3 chemotherapy alone. 3,4
Median duration of remission was 14.8 months (95% CI: 8.3 – NA; calculated by Kaplan Meier method).
Median event free survival was 11.3 months.
The data were presented yesterday during an oral scientific session at the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Expo in Atlanta.

Across both populations, GMI-1271 was well tolerated with no obvious incremental toxicity observed and lower than expected rates of severe, debilitating, grade 3-4 mucositis reported (e.g., 3% incidence reported vs. historical 20-25% incidence with MEC alone).

"These new data from our Phase 1/2 clinical trial demonstrate that encouraging clinical outcomes are possible for both duration of remission and survival endpoints when GMI-1271 is added to chemotherapy in two distinct AML patient populations," noted Helen Thackray, M.D., FAAP, GlycoMimetics Senior Vice-President, Clinical Development and Chief Medical Officer. "Beyond the high response rates previously reported with GMI-1271, we can now point to additional long-term endpoints that further support our plan to move the drug candidate into a Phase 3 clinical trial scheduled to begin in mid-2018. Importantly, with respect to safety, the low mucositis rate in relapsed and refractory patients receiving MEC induction chemotherapy — where you would expect around 25% severe mucositis — is quite striking. This was predicted and explained by preclinical models in which GMI-1271 blocked inflammatory macrophages trafficking to the gut and thus prevented mucosal injury."

"These results continue to show that AML patients treated with GMI-1271 consistently perform better than expected," said Daniel J. DeAngelo, M.D., Ph.D., the trial’s lead investigator and Director of Clinical and Translational Research, Adult Leukemia Program, at the Dana-Farber Cancer Institute and Brigham and Women’s Hospital, who presented the data at the ASH (Free ASH Whitepaper) Annual Meeting. "Our Phase 2 population consists of very high-risk patients based on age, disease status, and cytogenetic risk factors. The updated data continue to support the concept that disrupting the relationship between leukemic cells and the protective bone marrow microenvironment, when combined with chemotherapy, could improve the outlook and prognosis for these patients."

The second oral presentation at the ASH (Free ASH Whitepaper) meeting highlighted a preclinical study in murine models of AML in which E-selectin was shown to be upregulated, and AML cells binding to E-selectin increased chemo-resistance by activating specific tumor cell survival signaling pathways. This effect within the bone marrow microenvironment is unique to E-selectin as compared to other vascular adhesion molecules and can be blocked by GMI-1271. This translational research provides important evidence that elucidates how treatment with GMI-1271 appears to be improving sensitivity to chemotherapy.

"Given response rates we’ve observed to date that suggest clinical benefit in combination with chemotherapy in two AML populations, this preclinical work provides important further support for the mechanism of action of GMI-1271," noted Dr. Thackray. "Together, the clinical and preclinical data we have shared at the ASH (Free ASH Whitepaper) Annual Meeting demonstrate that GMI-1271 could represent a novel and truly differentiated approach to treatment of AML," Dr. Thackray concluded.

Meeting abstracts are available on ASH (Free ASH Whitepaper)’s website.

GlycoMimetics to Hold Post-ASH Meeting Briefing in Boston on December 19

GlycoMimetics will hold a briefing for investors/analysts, which will also be available via webcast, to review the GMI-1271 program with a focus on the AML clinical data presented at the ASH (Free ASH Whitepaper) Annual Meeting, at the Langham Hotel in Boston, December 19, at 7:30 a.m. EST. Dr. DeAngelo will present the clinical data from the ASH (Free ASH Whitepaper) oral presentation and respond to questions from on-site participants.

On December 12, 2017 Geron Corporation (Nasdaq:GERN) reported four presentations related to imetelstat at the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting and Exposition held in Atlanta, Georgia from December 9-12, 2017 (Press release, Geron, DEC 12, 2017, View Source;p=RssLanding&cat=news&id=2322273 [SID1234522575]). Imetelstat is a telomerase inhibitor initially developed by Geron and exclusively licensed to Janssen Biotech, Inc. (Janssen) on a worldwide basis.

"We and our partner are pleased to have this first presentation of data from IMerge displaying an 8-week transfusion independence rate of 54% among the subset of patients who were naïve to lenalidomide and HMAs and who lacked del(5q), which suggests that imetelstat could offer lower risk MDS patients a much-needed treatment option," said John A. Scarlett, M.D., Geron’s President and Chief Executive Officer. "In addition, the non-clinical data presentations continue to support the potential use of imetelstat in multiple hematologic malignancies. We continue to be encouraged by the consistent interest in imetelstat by collaborators around the world."

Clinical Data Presentation

Title: Efficacy and Safety of Imetelstat in RBC Transfusion-Dependent (TD) IPSS Low/Int-1 MDS Relapsed/Refractory to Erythropoiesis-Stimulating Agents (ESA) (IMerge) (Abstract #4256)

This poster presentation described data from the first 32 patients enrolled in Part 1 of IMerge, the ongoing Phase 2/3 clinical trial of imetelstat in red blood cell (RBC) transfusion-dependent (TD) patients with lower risk MDS. TD is defined as an RBC transfusion requirement of ≥4 units over 8 weeks prior to entry into the trial. The primary efficacy endpoint is the rate of RBC transfusion-independence (TI) lasting at least 8 weeks, defined as the proportion of patients without any RBC transfusion during any consecutive 8 weeks since entry to the trial. Key secondary endpoints are the rate of 24-week TI and the rate of hematologic improvement-erythroid (HI-E), defined as a rise in hemoglobin of at least 1.5 g/dL above the pretreatment level for at least 8 weeks or a reduction of at least 4 units of RBC transfusions over 8 weeks compared with the prior RBC transfusion burden. IMerge is designed in two parts: Part 1 is a Phase 2, open-label, single-arm trial of imetelstat administered as a single agent by intravenous infusion, and Part 2 is designed to be a Phase 3, randomized, controlled trial.

Data as of October 2017 with a median follow-up of 66.1 weeks in Part 1 were presented. Part 2 has not yet begun.

Efficacy in the Overall Trial Population (n=32):

38% (12/32) of patients achieved ≥8-week RBC TI
Mean relative reduction in transfusion burden from baseline was 64%
16% (5/32) of patients achieved ≥24-week RBC TI, with the median TI duration exceeding one year in these patients
63% (20/32) of patients achieved an erythroid hematologic improvement (HI-E)
Efficacy in the Lenalidomide and HMA Naïve and Non-Del(5q) Subset (n=13):

54% (7/13) of patients achieved ≥8-week RBC TI
Mean relative reduction in transfusion burden from baseline was 71%
31% (4/13) of patients achieved ≥24-week RBC TI
69% (9/13) of patients achieved an HI-E
Safety Summary:

Cytopenias, particularly neutropenia and thrombocytopenia, were the most frequently reported adverse events which were predictable, manageable and reversible
Link to IMerge poster: Fenaux P, et al. ASH (Free ASH Whitepaper) 2017

Based on these data, Part 1 of IMerge is being expanded to enroll approximately 20 additional patients who are naïve to lenalidomide and HMA treatment and are non-del(5q) to increase the experience and confirm the benefit-risk profile of imetelstat in this refined target patient population.

Non-Clinical Data Presentations

Data were presented from three non-clinical studies by academic scientists in collaboration with Janssen.

Title: Imetelstat, a Telomerase Inhibitor, Is Capable of Depleting Myelofibrosis Hematopoietic Stem Cells and Progenitor Cells (Abstract #1654)

This poster presentation described the effects of imetelstat on normal and myelofibrosis (MF) stem and progenitor cells in non-clinical models. The data showed that imetelstat inhibited the proliferation and differentiation of MF progenitor and stem cells in hematopoietic colony assays and xenograft models, but had minimal effects on normal hematopoietic stem and progenitor cells in such experiments. Imetelstat treatment of MF stem and progenitor cells reduced telomerase activity and induced apoptosis. These data provide further support that imetelstat may selectively inhibit the proliferation of and promote apoptosis in MF progenitor and stem cells, suppressing the malignant clones that drive the disease in patients.

Title: Telomerase Inhibition Impairs Self-Renewal of b-Catenin Activated Myeloproliferative Neoplasm Progenitors (Abstract #2860)

This poster presentation described the potential impact of imetelstat on leukemia stem cells in non-clinical models of chronic myeloid leukemia (CML) in blast crisis. The data suggest that imetelstat plus dasatinib, a standard treatment for CML, may inhibit self-renewal of blast crisis cells in vitro compared with normal bone marrow progenitors. In mouse xenograft models of blast crisis CML, imetelstat treatment reduced the number of leukemia progenitor cells detected in bone marrow and spleen, decreased spleen size, inhibited the self-renewal capacity and prolonged survival compared to controls. These data suggest that imetelstat may inhibit proliferation of malignant progenitors in CML.

Title: Integrated Molecular Analysis Identifies Replicative Stress as Sensitizer to Imetelstat Therapy in AML (Abstract #798)

This oral presentation described imetelstat’s activity in human acute myeloid leukemia (AML) patient-derived xenograft models. The preclinical data demonstrated that imetelstat prolonged overall survival of AML xenografts derived from 17 out of 30 individual patient samples compared to saline-treated controls. Molecular analysis showed that sustained responders were associated with gene signatures of replicative stress at baseline. The data also suggest that inducing replicative stress with standard induction chemotherapy may sensitize poorly responding samples to imetelstat. These data build on previously published preclinical work and further support potential application of imetelstat in the treatment of AML.

Webcast Investor Event

Management will be hosting a live webcast of an analyst and investor meeting on December 19, 2017 at 8:30 a.m. ET to discuss the imetelstat clinical data in MDS presented at ASH (Free ASH Whitepaper). The audio and slide presentation webcast will be accessible at www.geron.com on the Investor Relations pages, under Events. Following the live presentation, the webcast will be archived and available for replay at the same address for a period of 30 days.

About Imetelstat

Imetelstat (GRN163L; JNJ-63935937) is a potent and specific inhibitor of telomerase that is administered by intravenous infusion. This first-in-class compound, discovered by Geron, is a specially designed and modified short oligonucleotide, which targets and binds directly with high affinity to the active site of telomerase. Preliminary clinical data suggest imetelstat might have disease-modifying activity by inhibiting the progenitor cells of the malignant clones associated with hematologic malignancies in a relatively select manner. Most commonly reported adverse events in imetelstat clinical studies include fatigue, gastrointestinal symptoms and cytopenias. Imetelstat has not been approved for marketing by any regulatory authority.

About the Collaboration with Janssen

On November 13, 2014, Geron entered into an exclusive worldwide license and collaboration agreement with Janssen Biotech, Inc., to develop and commercialize imetelstat for oncology, including hematologic myeloid malignancies, and all other human therapeutics uses. Under the terms of the agreement, Geron received an upfront payment of $35 million and is eligible to receive additional payments up to a potential total of $900 million for the achievement of development, regulatory and commercial milestones, as well as royalties on worldwide net sales. All regulatory, development, manufacturing and promotional activities related to imetelstat are being managed through a joint governance structure, with Janssen responsible for these activities.

On December 12, 2017 Roche (SIX: RO, ROG; OTCQX: RHHBY) reported the first results from the pivotal phase III MURANO study evaluating Venclexta/Venclyxto (venetoclax) plus MabThera/Rituxan (rituximab) compared to bendamustine plus MabThera/Rituxan (BR) for the treatment of people with relapsed or refractory chronic lymphocytic leukaemia (CLL) (Press release, Hoffmann-La Roche, DEC 12, 2017, View Source [SID1234522580]). The results showed that a fixed duration of treatment with Venclexta/Venclyxto plus MabThera/Rituxan significantly reduced the risk of disease progression or death (progression-free survival; PFS, as assessed by investigator) by 83% compared with BR (HR=0.17; 95% CI 0.11-0.25; p<0.0001).

"The MURANO study results indicate that Venclexta/Venclyxto plus MabThera/Rituxan has the potential to provide an important new chemotherapy-free option for people with previously treated chronic lymphocytic leukaemia," said Sandra Horning, MD, Roche’s Chief Medical Officer and Head of Global Product Development. "We are particularly encouraged by the magnitude of benefit observed across key efficacy measures compared to a current standard of care, and we look forward to discussing these results with health authorities."

Results from the study were featured in the official press programme of the 59th American Society of Hematology (ASH) (Free ASH Whitepaper) Annual Meeting in Atlanta on Monday, 11 December, and will be presented during the Late-Breaking Abstracts Session on Tuesday, 12 December, at 7.45am EST by John F. Seymour, MD, Peter MacCallum Cancer Centre and Royal Melbourne Hospital, Melbourne, Australia (Abstract #LBA-2).

Data from the MURANO study will be submitted to global health authorities, including the US Food and Drug Administration (FDA), which has granted Breakthrough Therapy Designation for Venclexta in combination with Rituxan for the treatment of relapsed or refractory CLL based on promising results from the phase Ib M13-365 study.

Venclexta was granted accelerated approval by the FDA in April 2016 for the treatment of people with CLL with 17p deletion, as detected by an FDA approved test, who have received at least one prior therapy. The MURANO study is part of the company’s commitment in the United States to convert the current accelerated approval of Venclexta to a full approval.

A robust clinical development programme for Venclexta/Venclyxto is ongoing, and additional results across multiple blood cancers including acute myeloid leukaemia (AML) and multiple myeloma (MM) were also presented at the ASH (Free ASH Whitepaper) Annual Meeting.

About the MURANO Study
MURANO (NCT02005471) is a phase III open-label, international, multicentre, randomised study evaluating the efficacy and safety of Venclexta/Venclyxto in combination with MabThera/Rituxan compared to bendamustine in combination with MabThera/Rituxan (BR). All treatments were of fixed duration. The study included 389 patients with relapsed or refractory chronic lymphocytic leukaemia (CLL) who had been previously treated with at least one, but not more than three, lines of therapy. Patients were randomly assigned in a 1:1 ratio to receive either Venclexta/Venclyxto plus MabThera/Rituxan (Arm A) or BR (Arm B). The primary endpoint of the study is investigator-assessed progression-free survival (PFS). Secondary endpoints include PFS assessed by independent review committee (IRC), overall response rate (ORR), complete response rate (with or without complete blood count recovery, CR/CRi), overall survival (OS), minimal residual disease (MRD) status, duration of response, event-free survival and time to next CLL treatment.

The results showed:

Patients in the study who received Venclexta/Venclyxto plus MabThera/Rituxan lived significantly longer without their disease worsening (PFS, as assessed by investigator) compared to those who received BR (HR=0.17; 95% CI, 0.11-0.25; p<0.0001; median PFS: not reached vs. 17.0 months, respectively).
At two years, 84.9% of patients in the Venclexta/Venclyxto plus MabThera/Rituxan arm had not experienced disease progression, compared to 36.3% of patients in the BR arm.
Consistent benefit was observed in all patient subgroups for Venclexta/Venclyxto plus MabThera/Rituxan compared to BR, including high-risk and low-risk groups.
IRC assessment was consistent; as assessed by IRC, Venclexta/Venclyxto plus MabThera/Rituxan reduced the risk of disease progression or death by 81% compared to BR (HR=0.19; 95% CI 0.13, 0.28; p<0.0001).
Clinical benefit observed for Venclexta/Venclyxto plus MabThera/Rituxan compared to BR was consistent across key secondary endpoints, including OS (HR=0.48, 95% CI 0.25-0.90; medians not yet reached), ORR as assessed by investigator (93.3% vs. 67.7%), CR/CRi as assessed by investigator (26.8% vs. 8.2%). These results were not statistically significant. In addition, higher rates of MRD-negativity at any time were observed with Venclexta/Venclyxto plus MabThera/Rituxan compared to BR (83.5% vs. 23.1%). MRD negativity was defined as less than one CLL cell in 10,000 leukocytes.
No new safety signals were observed with the treatment combination of Venclexta/Venclyxto plus MabThera/Rituxan. The most common Grade 3-4 adverse events with Venclexta/Venclyxto plus MabThera/Rituxan compared to BR, respectively, were low white blood cell count (57.7% vs. 38.8%), low red blood cell count (10.8% vs. 13.8%), low platelet count (5.7% vs. 10.1%), low white blood cell count with fever (3.6% vs. 9.6%), pneumonia (5.2% vs. 8.0%) and infusion reactions (1.5% vs. 5.3%).
About Venclexta/Venclyxto
Venclexta/Venclyxto is a small molecule designed to selectively bind and inhibit the BCL-2 protein, which plays an important role in a process called apoptosis (programmed cell death). Overexpression of the BCL-2 protein in CLL has been associated with resistance to certain therapies. It is believed that blocking BCL-2 may restore the signalling system that tells cells, including cancer cells, to self-destruct. Venclexta/Venclyxto is being developed by Roche and AbbVie. It is jointly commercialised by AbbVie and Genentech, a member of the Roche Group, in the United States and commercialised by AbbVie outside of the United States.

Together, the companies are committed to further research with Venclexta/Venclyxto, which is currently being evaluated in phase III clinical trials for the treatment of CLL, along with studies in several other types of cancers. In the United States, Venclexta has been granted four breakthrough therapy designations by the FDA: in combination with Rituxan for people with relapsed or refractory 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 leukaemia (AML) ineligible for intensive chemotherapy, and in combination with low-dose cytarabine (LDAC) for people with untreated AML ineligible for intensive chemotherapy.

About Chronic Lymphocytic Leukaemia
Chronic lymphocytic leukaemia (CLL) is the most common type of leukaemia in the Western world.1 CLL mainly affects men and the median age at diagnosis is about 70 years.2 Worldwide, the incidence of all leukaemias is estimated to be over 350,0001 and CLL is estimated to affect around one-third of all people newly diagnosed with leukaemia.3
