"At Merck, working to help prevent certain HPV-related cancers has been a priority for more than two decades," said Dr. Alain Luxembourg, director, clinical research, Merck Research Laboratories. "Today’s approval for the prevention of HPV-related oropharyngeal and other head and neck cancers represents an important step in Merck’s mission to help reduce the number of men and women affected by certain HPV-related cancers."

GARDASIL 9 is a vaccine indicated in females 9 through 45 years of age for the prevention of cervical, vulvar, vaginal, anal, oropharyngeal and other head and neck cancers caused by human papillomavirus (HPV) Types 16, 18, 31, 33, 45, 52, and 58; cervical, vulvar, vaginal, and anal precancerous or dysplastic lesions caused by HPV Types 6, 11, 16, 18, 31, 33, 45, 52, and 58; and genital warts caused by HPV Types 6 and 11.

GARDASIL 9 is indicated in males 9 through 45 years of age for the prevention of anal, oropharyngeal and other head and neck cancers caused by HPV Types 16, 18, 31, 33, 45, 52, and 58; anal precancerous or dysplastic lesions caused by HPV Types 6, 11, 16, 18, 31, 33, 45, 52, and 58; and genital warts caused by HPV Types 6 and 11.

GARDASIL9 (Human Papillomavirus 9-valent Vaccine, Recombinant) is contraindicated in individuals with hypersensitivity, including severe allergic reactions to yeast, or after a previous dose of GARDASIL 9 or GARDASIL [Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant].

Both men and women can be at risk for HPV-attributable oropharyngeal cancer; however, this cancer affects men five times more than women.1 For most people, HPV clears on its own. But, for those who don’t clear the virus, it can cause certain cancers. Oropharyngeal cancer can arise as a result of HPV infection in the oropharynx, which includes the soft palate, side and back wall of the throat, tonsils, and back one-third of the tongue. According to a recent model published by the U.S. Centers for Disease Control and Prevention (CDC), HPV-attributable oropharyngeal cancer has surpassed cervical cancer as the most prevalent type of HPV-related cancer in the U.S.1

1 The CDC analyzed data from the U.S. Cancer Statistics (USCS) to assess the incidence of HPV-associated cancers and to estimate the annual number of cancers caused by HPV, overall and by state, during 2012 to 2016.

The estimated number of HPV-attributable cancers was calculated by multiplying the average number of HPV-associated cancers by the percentage of HPV-attributable cancers diagnosed from 1993 to 2005, before HPV vaccination was available in the U.S.

The detection of HPV DNA in an HPV study is not enough to determine that HPV caused the cancer.

Not all cervical and oropharyngeal cancers are caused by HPV.

Important Information About GARDASIL 9

GARDASIL 9 does not eliminate the necessity for vaccine recipients to undergo screening for cervical, vulvar, vaginal, anal, oropharyngeal and other head and neck cancers as recommended by a healthcare provider.

GARDASIL 9 has not been demonstrated to provide protection against diseases caused by:

HPV types not covered by the vaccine
HPV types to which a person has previously been exposed through sexual activity
Not all vulvar, vaginal, anal, oropharyngeal and other head and neck cancers are caused by HPV, and GARDASIL 9 protects only against those vulvar, vaginal, anal, oropharyngeal and other head and neck cancers caused by HPV Types 16, 18, 31, 33, 45, 52, and 58.

GARDASIL9 (Human Papillomavirus 9-valent Vaccine, Recombinant) is not a treatment for external genital lesions; cervical, vulvar, vaginal, anal, oropharyngeal and other head and neck cancers; or cervical intraepithelial neoplasia (CIN), vulvar intraepithelial neoplasia (VIN), vaginal intraepithelial neoplasia (VaIN), or anal intraepithelial neoplasia (AIN).

Vaccination with GARDASIL 9 may not result in protection in all vaccine recipients.

Select Safety Information for GARDASIL 9

GARDASIL 9 is contraindicated in individuals with hypersensitivity, including severe allergic reactions to yeast, or after a previous dose of GARDASIL 9 or GARDASIL [Human Papillomavirus Quadrivalent (Types 6, 11, 16 and 18) Vaccine, Recombinant].

Because vaccinees may develop syncope, sometimes resulting in falling with injury, observation for 15 minutes after administration is recommended. Syncope, sometimes associated with tonic-clonic movements and other seizure-like activity, has been reported following HPV vaccination. When syncope is associated with tonic-clonic movements, the activity is usually transient and typically responds to restoring cerebral perfusion.

Safety and effectiveness of GARDASIL 9 have not been established in pregnant women.

The most common (≥10%) local and systemic adverse reactions in females were injection-site pain, swelling, erythema, and headache. The most common (≥10%) local and systemic reactions in males were injection-site pain, swelling, and erythema.

The duration of immunity of GARDASIL 9 has not been established.

Dosage and Administration for GARDASIL 9

GARDASIL 9 should be administered intramuscularly in the deltoid or anterolateral area of the thigh.

For individuals 9 through 14 years of age, GARDASIL 9 can be administered using a 2-dose or 3-dose schedule. For the 2-dose schedule, the second dose should be administered 6-12 months after the first dose. If the second dose is administered less than 5 months after the first dose, a third dose should be given at least 4 months after the second dose. For the 3-dose schedule, GARDASIL 9 should be administered at 0, 2 months, and 6 months.
For individuals 15 through 45 years of age, GARDASIL 9 is administered using a 3-dose schedule at 0, 2 months, and 6 months.
About HPV and HPV-related Cancers and Diseases

According to the CDC, an estimated 14 million new HPV infections occur every year in the United States. HPV is so common that 80% of people who are sexually active get HPV at some point in their life. For most people, HPV clears on its own; but for those who don’t clear the virus, it could cause certain cancers and diseases. There is no way to know which people who have HPV will develop cancer or other health problems. GARDASIL9 (Human Papillomavirus 9-valent Vaccine, Recombinant) helps protect against seven HPV types that cause the majority of HPV-related cancers in the United States. Persistent HPV infection can also lead to pre-cancerous lesions that may require additional follow-up procedures. With the exception of cervical cancer, there is no routinely recommended screening for the detection of HPV-related cancers.

On June 12, 2020 DCprime, the front-runner in the field of relapse vaccines, in collaboration with the University of Bergen, reported the presentation of a novel preclinical animal model tailored for cancer vaccine research at the virtual 25th European Hematology Association (EHA) (Free EHA Whitepaper) Congress (EHA) (Free EHA Whitepaper) (Press release, DCPrime, JUN 12, 2020, View Source [SID1234561871]). The humanized immunocompetent mouse model was applied to evaluate DCprime’s lead product DCP-001 as a standalone vaccine against leukemic cells, and will also enable future evaluation of DCP-001 in combination with chemotherapy or immune modulators. The full abstract and poster are available via the EHA (Free EHA Whitepaper) Meeting’s website.

"This crucial animal model will be invaluable in advancing our pre-clinical knowledge of DCP-001 and its development could not have been accomplished without the expertise from our partners at the University of Bergen," said Jeroen Rovers, MD, PhD, Chief Medical Officer of DCprime. "We look forward to working closely with Bergen University on future research initiatives as well as within the public-private consortium AML-VACCiN that continues to drive the clinical development of DCP-001 despite the current challenges in clinical practice due to COVID-19."

"We are excited to support DCprime’s novel cancer relapse vaccine strategy as a potential future therapy to efficiently keep hematological cancers in check. Generating a mouse model that supports the xenograft of leukemic cell lines in conjunction with systemic engraftment of a human immune system, has been very instrumental to demonstrate the therapeutic potential of DCP-001 as a cell-based cancer vaccine," commented Professor Bjørn Tore Gjertsen, Department of Clinical Science at the University of Bergen

DCprime’s lead cancer relapse vaccine candidate DCP-001 is generated by transforming a proprietary leukemic cell, DCOne, into a whole cell-based cancer vaccine. Clinical data from a previously concluded phase 1 clinical study that was presented at the 61st Annual Meeting and Exposition of the American Society of Hematology (ASH) (Free ASH Whitepaper) in December 2019 demonstrated DCP-001’s potential to prolong relapse-free survival and overall survival as an allogeneic, off-the-shelf cell-based vaccine in the post-remission setting.

DCP-001 is currently being evaluated in the international, multi-center, open-label proof-of-concept study ADVANCE-II with AML patients in complete remission, but with persistent measurable residual disease (MRD). The associated AML-VACCiN consortium receives support from the EU under the Horizon 2020 program. More information can be found at www.amlvaccin.eu.

On June 12, 2020 Geron Corporation (Nasdaq: GERN), a late-stage clinical biopharmaceutical company, reported that an oral presentation and three poster presentations of new clinical data and analyses related to imetelstat, the Company’s first-in-class telomerase inhibitor, are now available on Geron’s website as well as to participants of the Virtual Edition of the 25th Annual EHA (Free EHA Whitepaper) Annual Congress (Press release, Geron, JUN 12, 2020, View Source [SID1234561082]).

Updated Efficacy and Safety Data from IMerge Phase 2 Clinical Trial in Lower Risk Myelodysplastic Syndromes (MDS)

"The EHA (Free EHA Whitepaper) presentation reports encouraging continued durability data from the IMerge Phase 2 clinical trial, including a median duration of 8-week transfusion independence of 20 months, which is the longest duration we have reported to date in this trial, and that 29% of patients were transfusion free for more than one year," said Aleksandra Rizo, M.D., Ph.D., Geron’s Chief Medical Officer. "We expect these data to drive further interest of investigators, which will promote enrollment for the ongoing IMerge Phase 3 clinical trial in lower risk MDS."

Title: Treatment with Imetelstat Provides Durable Transfusion Independence (TI) in Heavily Transfused Non-del(5q) Lower Risk MDS (LR-MDS) Relapsed/Refractory (R/R) to Erythropoiesis Stimulating Agents (ESAs) (Abstract #S183)

The oral presentation reports long-term efficacy and safety data from 38 patients in the IMerge Phase 2 clinical trial, based on a February 4, 2020 cut-off date and a median follow-up of 24 months. IMerge is a two-part Phase 2/3 clinical trial evaluating imetelstat in transfusion dependent patients with Low or Intermediate-1 risk myelodysplastic syndromes (lower risk MDS), who are relapsed after or refractory to prior treatment with ESAs. The first part of IMerge was designed as a Phase 2, open label, single arm study to assess the efficacy and safety of imetelstat. The primary efficacy endpoint is 8-week TI rate, which is defined as the proportion of patients achieving red blood cell transfusion independence during any consecutive eight weeks since entry into the trial. Secondary endpoints include rate of hematologic improvement-erythroid (HI-E) and duration of TI. Several patients remain on treatment in the IMerge Phase 2 clinical trial.

The conclusions of the oral presentation are as follows:

Meaningful and durable transfusion independence (TI):
° High rates of TI and HI-E: 42% 8-week TI rate and 68% HI-E rate
° Durable TI and HI-E: Median duration of TI is 20 months and median duration of HI-E is 21 months
° TI across multiple patient subtypes: ringed sideroblast positive (RS+) and RS-, high and very high transfusion burden

Potential disease-modifying activity:
° 29% of patients transfusion free for more than 1 year
° 75% of 8-week TI responders had a hemoglobin rise of > 3g/dL from pretreatment level
° Reduction in variant allele frequency (VAF) of SF3B1 mutation correlated with shorter time to TI and duration of TI

No new safety signal identified:
° Reversible cytopenias, without significant clinical consequences were most frequent adverse events
The slide presentation is available on Geron’s website at www.geron.com/r-d/publications.

Ongoing IMerge Phase 3 Clinical Trial

The IMerge Phase 3 clinical trial is a double-blind, randomized, placebo-controlled clinical trial with registration intent. The trial is designed to enroll approximately 170 patients with lower risk transfusion dependent MDS who are relapsed or refractory to an ESA, have not received prior treatment with either a hypomethylating agent (HMA) or lenalidomide and who are non-del(5q). The trial was opened for screening and enrollment in August 2019. As of the end of April 2020, approximately 68% of planned clinical sites for the IMerge Phase 3 trial were open for enrollment. Geron expects to complete patient enrollment by the end of the first quarter of 2021. Under current assumptions, the Company expects top-line results to be available in the second half of 2022.

New Analyses of Data from IMbark Phase 2 Clinical Trial in Intermediate-2 or High-risk Myelofibrosis

"Taken together, we believe the three EHA (Free EHA Whitepaper) poster presentations reporting new analyses of IMbark Phase 2 data substantiate the OS outcome observed in IMbark and indicate potential disease-modifying activity of imetelstat in yet another hematologic indication," said Aleksandra Rizo, M.D., Ph.D., Geron’s Chief Medical Officer. "These analyses also provide further support for our planned Phase 3 clinical trial in refractory MF, which is expected to open for enrollment in the first quarter of 2021."

IMbark was designed as a Phase 2 clinical trial to evaluate two dosing regimens of imetelstat (either 4.7 mg/kg or 9.4 mg/kg administered by intravenous infusion every three weeks) in patients with Intermediate-2 or High-risk myelofibrosis (MF) who have relapsed after or are refractory to prior treatment with a janus kinase inhibitor (JAKi). The co-primary efficacy endpoints for IMbark were spleen response rate, defined as the proportion of patients who achieve a reduction of at least 35% in spleen volume as assessed by imaging, and symptom response rate, defined as the proportion of patients who achieve a reduction of at least 50% in Total Symptom Score (TSS), at 24 weeks. Key secondary endpoints were overall survival (OS) and safety.

Title: Telomerase Activity, Telomere Length and hTERT Expression Correlate with Clinical Outcomes in Higher-Risk Myelofibrosis (MF) Relapsed/Refractory (R/R) to Janus Kinase Inhibitor Treated with Imetelstat (Abstract #EP1098)

The conclusions of the poster are as follows:

Imetelstat achieved dose- and exposure-dependent reduction of telomerase activity and human reverse transcriptase (hTERT) expression level, demonstrating on-target mechanism of action.
Achieving optimal pharmacodynamic (PD) effect in patients treated with imetelstat is correlated with longer OS, as well spleen and symptom response.
Significant dose-dependent reduction in VAF of JAK2, CALR and MPL mutations were observed, indicating that imetelstat has disease-modifying activity by targeting the underlying MF malignant clones.
Treatment with 9.4mg/kg of imetelstat improved clinical outcomes in patients with short telomeres or high hTERT expression level at baseline. The results are consistent with telomere biology in cancer cells and provide evidence for on-target mechanism of action of imetelstat through telomerase inhibition.
This is the first clinical report to systematically evaluate the mechanism of action based PD effect of imetelstat, and its relationship to exposure and clinical benefits.
The poster presentation is available on Geron’s website at www.geron.com/r-d/publications.

Title: Imetelstat Treatment Results in Clinical Benefits, Including Improved Overall Survival, in Patients with Higher-Risk Triple Negative Myelofibrosis Relapsed/Refractory to Janus Kinase Inhibitors (JAKI) (Abstract #1101)

The overall conclusion of the poster is that triple negative (TN) patients who are relapsed/refractory to JAKi and treated with 9.4 mg/kg of imetelstat had better clinical outcomes and prolonged overall survival (OS) compared to non-TN patients, suggesting that imetelstat may improve the poor outcomes expected for TN patients. Additional highlights from the poster include:

With 9.4 mg/kg of imetelstat treatment, clinical response rates were higher in TN vs non-TN pts: spleen response rate was 18.8% in TN vs 7.3% in non-TN; and symptom response was 50.0% in TN vs 24.4% in non-TN patients.
Imetelstat treatment at 9.4 mg/kg resulted in significantly longer median OS of 35.9 months for TN patients compared to 24.6 months for non-TN patients.
A majority (94%) of the TN patients enrolled on the study had grade three fibrosis. Higher rate of bone marrow fibrosis improvement was noted in the TN (50%) vs non-TN (39.1%) patients.
TN patients enrolled on the study had short telomere length and high hTERT expression level at baseline, representing a suitable target population for imetelstat, a first-in-class telomerase inhibitor.
The poster presentation is available on Geron’s website at www.geron.com/r-d/publications.

Title: Favorable Overall Survival with Imetelstat Treatment Correlates with Other Clinical Benefits in Intermediate-2 or High-Risk Myelofibrosis Relapsed/Refractory to Janus Kinase Inhibitor (Abstract #1107)

The poster reports new analyses of data from all 107 patients in both arms (59 patients in the 9.4 mg/kg arm and 48 patients in the 4.7 mg/kg arm) of the IMbark Phase 2 clinical trial with a data cut-off date of February 19, 2020 and a median follow-up of 41.7 months. As of the data cut-off date, median OS was 28.1 months in the 9.4 mg/kg arm and 19.9 months in the 4.7 mg/kg arm.

The overall conclusion of the poster was that imetelstat showed dose-related improvement in OS in patients who are R/R to JAKi. The survival benefit observed with imetelstat was supported by the trend of correlation with other clinical benefits. Additional highlights from the poster include:

Among 57 patients across both treatment arms that had matching bone marrow samples, 20 patients (35%) had ≥1 degree of bone marrow fibrosis improvement while on study and had a significantly longer OS than those who had worsening bone marrow fibrosis. A similar trend was seen in 29 patients (51%) with stable vs. worsening fibrosis.
Patients who achieved symptom and spleen response at week 24 showed a trend of longer OS compared to patients who did not achieve response.
Transfusion dependency, response to last JAKi, higher baseline neutrophils, lower baseline hemoglobin and platelet values correlated with increased risk of death.
The poster presentation is available on Geron’s website at www.geron.com/r-d/publications.

Planned Phase 3 Clinical Trial in Refractory MF

The planned Phase 3 clinical trial in refractory MF is designed to be an open label 2:1 randomized, controlled trial with registration intent to evaluate imetelstat (9.4 mg/kg administered by intravenous infusion every three weeks) in approximately 320 patients with Intermediate-2 or High-risk MF. Patients eligible for the trial will be required to be refractory to a JAK inhibitor, an inclusion criterion that is planned to be defined as having an inadequate spleen response or symptom response after treatment with a JAK inhibitor for at least six months, including an optimal dose of a JAK inhibitor for at least two months. The control arm is planned to be best available therapy (BAT), excluding JAK inhibitors. The primary efficacy endpoint for the trial is planned to be overall survival (OS). Planned key secondary endpoints include symptom response, spleen response, progression free survival, complete response, partial response, clinical improvement, duration of response, safety, pharmacokinetics, and patient reported outcomes. Under current assumptions, the Company expects to complete patient enrollment in the second half of 2022, to conduct an interim analysis in the first half of 2023 and to conduct a final analysis in the first half of 2024. The final analysis for OS is planned to be conducted after more than 50% of the patients planned to be enrolled in the trial have died. An interim analysis of OS is planned to be conducted after approximately 70% of the total projected number of events for the final analysis have occurred. Both the planned interim and final analyses are event driven and could occur on different timelines than currently expected.

About Imetelstat

Imetelstat is a novel, first-in-class telomerase inhibitor exclusively owned by Geron and being developed in hematologic myeloid malignancies. Early clinical data suggest imetelstat may have disease-modifying activity through the apoptosis of malignant stem and progenitor cells, which allows potential recovery of normal hematopoiesis. Geron’s imetelstat development program includes two ongoing or planned registration-enabling studies, IMerge, an ongoing Phase 2/3 clinical trial in lower risk myelodysplastic syndromes (MDS), and a planned Phase 3 clinical trial in refractory myelofibrosis (MF) expected to be open for patient screening and enrollment in the first quarter of 2021. Imetelstat has been granted Fast Track designation by the U.S. Food and Drug Administration for both the treatment of patients with non-del(5q) lower risk MDS who are refractory or resistant to an erythropoiesis-stimulating agent and for patients with Intermediate-2 or High-risk MF whose disease has relapsed after or is refractory to janus kinase (JAK) inhibitor treatment.

On June 12, 2020 BeiGene, Ltd. (NASDAQ: BGNE; HKEX: 06160), a commercial-stage biotechnology company focused on developing and commercializing innovative molecularly-targeted and immuno-oncology drugs for the treatment of cancer, reported that data on its BTK inhibitor zanubrutinib in relapsed/refractory (R/R) marginal zone lymphoma (MZL) and other B-cell malignancies and its anti-PD-1 antibody tislelizumab in R/R NK/T-cell lymphomas were presented at the 25th European Hematology Association (EHA) (Free EHA Whitepaper) Virtual Congress, taking place on June 11-14 (Press release, BeiGene, JUN 12, 2020, View Source [SID1234561081]).

"We’re pleased to share clinical results from several trials in our broad hematology development program at this year’s EHA (Free EHA Whitepaper). Zanubrutinib demonstrated encouraging efficacy and safety in multiple indications, including R/R MZL, which expands on data presented previously," said Jane Huang, M.D., Chief Medical Officer, Hematology at BeiGene. "We look forward to receiving data from the potentially registration-enabling Phase 2 trial of zanubrutinib in R/R MZL, which has completed enrollment. "

Phase 1/2 Study of Zanubrutinib in R/R MZL

Abstract: EP1165

Data presented at EHA (Free EHA Whitepaper) were from the MZL cohort of an open-label, multicenter Phase 1/2 trial of zanubrutinib in patients with B-cell malignancies (NCT02343120). Twenty patients with R/R MZL were enrolled in this cohort, including nine with extranodal disease, five with nodal disease, and six with splenic disease.

"The high response rate observed in this study is encouraging, and zanubrutinib achieved durable responses across all subtypes. In addition, it was well tolerated among patients with R/R MZL," commented Alessandra Tedeschi, M.D., Niguarda Cancer Center, Italy.

At the data cutoff of January 29, 2020, with a median follow-up of 27.1 months (8.3 – 51.1), 12 patients remained on study treatment. Results included:

The overall response rate (ORR) assessed by investigator was 80% (95% confidence interval [CI]: 56.3, 94.3), with a complete response (CR) rate of 15% and a partial response (PR) rate of 65%;
In patients with extranodal MZL, the ORR was 77.8% (95% CI: 40.0, 97.2), including one CR and six PRs;
In patients with nodal MZL, the ORR was 100% (95% CI: 47.8, 100.0), including two CRs and three PRs; and
In patients with splenic MZL, the ORR was 66.7% (95% CI: 22.3, 95.7), including four PRs;
The median time to response (TTR) was 2.8 months (2.6-39.6);
At 18 months, 66.2% of responders remained in response (95% CI: 32.4, 86);
The progression-free survival (PFS) rate at 24 months was 59.4% (95% CI: 33, 79);
The overall survival (OS) rate at 24 months was 83.2% (95% CI: 56, 94);
Zanubrutinib was well tolerated in patients with R/R MZL:
All patients experienced at least one adverse event (AE), which were primarily grade 1 or 2 in severity. The most frequently reported AEs of any grade (≥20%) include diarrhea (35%), contusion (35%), rash (35%), upper respiratory tract infection (30%), neutropenia (25%), pyrexia (25%), nasopharyngitis (20%), sinusitis (20%), nausea (20%), and fatigue (20%);
The most common grade ≥3 AEs (≥10%) were neutropenia (15%), anemia (10%), and pyrexia (10%);
Serious AEs were reported in 45% of patients (9/20); and
One patient discontinued treatment due to an AE and there were no deaths reported.
Biomarker Identification in R/R Non-Germinal Center B-Cell-Like (Non-GCB) Diffuse Large B-Cell Lymphoma (DLBCL) Treated with Zanubrutinib

Abstract: EP1246

Data presented at EHA (Free EHA Whitepaper) were from four clinical trials evaluating efficacy and biomarker identification of zanubrutinib in patients with R/R non-GCB DLBCL, including two trials of zanubrutinib as a monotherapy (study 1: NCT04170283; study 2: NCT03145064) and two trials of zanubrutinib in combination with an anti-CD20 antibody (study 3: NCT02569476; study 4: NCT03520920). A total of 121 patients were included in the analysis, with 79 from the monotherapy trials and 42 from the combination trials. At the data cutoff of September 9, 2019 for study 1, August 31, 2019 for study 2 and 3, and May 31, 2019 for study 4, the results included:

Across all four trials, the unadjusted ORR in patients with non-GCB DLBCL was similar, with an average of 29.8% (22.7-35.0); the median PFS ranged from 2.8 to 4.9 months, and the median OS ranged from 8.4 to 11.8 months;
In the 49 patients with GEP-confirmed activated B-cell (ABC) DLBCL classification, the ORR tended to be higher (42.9%) than non-GCB DLBCL and was comparable for monotherapy (42.1%) and combination therapy (45.5%);
In the 56 non-GCB patients with HTG gene expression profiles, PAX5 expression was higher in monotherapy responders than non-responders, and PIM1, BCL2, and FOXP1 expression was higher in combination therapy responders than non-responders;
Patients with double expressions of MYC and BCL2 tended to have higher ORRs (61% vs. 29%, p=0.12)) and longer PFS (5.2 months vs. 3.6 months, p=0.16) and OS (10 months vs. 7 months, p = 0.21);
In the 77 patients with NGS panel data, those with CD79B mutations showed significantly higher ORR than the ones without (60% vs. 26.9%, p=0.005); and
All three patients with NOTCH1 mutations responded to zanubrutinib monotherapy.
Zanubrutinib in Combination with Rituximab in R/R Non-Hodgkin’s Lymphoma (NHL)

Abstract: EP1271

Data presented at EHA (Free EHA Whitepaper) were from a single-arm, multicenter Phase 2 trial of zanubrutinib in combination with rituximab in patients with R/R NHL (NCT03520920). A total of 41 patients were enrolled in this trial, including 20 with non-GCB DLBCL who previously received standard anthracycline ± rituximab-based treatment, 16 with follicular lymphoma (FL) who received at least one prior therapy, and five with MZL who received at least one prior therapy.

At the data cutoff of October 11, 2019, six patients remained on study treatment and the results included:

The ORR assessed by investigator per Lugano criteria with LYRIC modification for immunomodulatory drugs (Cheson et al 2016) was 31.8% (95% CI: 13.9, 54.9), with a CR rate of 18.2% and a PR rate of 13.6%;
The median DoR had not been reached and the median TTR was 5.75 months (2.14-14.29);
The median PFS was 2.7 months (95%CI: 1.45, 5.32) and the median PFS follow-up duration was 11.3 months;
Tislelizumab was generally well-tolerated, including:
The most frequently reported (≥15%) treatment-emergent adverse events (TEAEs) were anemia and pyrexia (27.3%, each) and hypoalbuminemia, hyperglycemia, and hypokalemia (18.2%, each);
Grade ≥3 TEAEs were reported in 11 (50%) patients; anemia and neutrophil count decrease were reported in at least two patients；
Serious TEAEs were reported in eight (36.4%) patients, with four patients determined to be possibly related to tislelizumab;
Immune-related (ir) TEAEs were reported in seven (31.8%) patients;
One patient experienced a TEAE of grade 5 respiratory failure leading to treatment discontinuation, which was not related to tislelizumab as assessed by investigator; and
One patient experienced a fatal TEAE.

About BRUKINSA (zanubrutinib)

BRUKINSA is a small molecule inhibitor of Bruton’s tyrosine kinase (BTK) discovered by BeiGene scientists that is currently being evaluated globally in a broad pivotal clinical program as a monotherapy and in combination with other therapies to treat various B-cell malignancies.

BRUKINSA was approved by the U.S. FDA to treat adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy on November 14, 2019. This indication was approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

BRUKINSA was approved in China for the treatment of MCL in adult patients who have received at least one prior therapy and CLL or SLL in adult patients who have received at least one prior therapy in June 2020.

BRUKINSA is not approved for use outside the United States and China.

IMPORTANT U.S. SAFETY INFORMATION FOR BRUKINSA (ZANUBRUTINIB)

Warnings and Precautions

Hemorrhage

Fatal and serious hemorrhagic events have occurred in patients with hematological malignancies treated with BRUKINSA monotherapy. Grade 3 or higher bleeding events including intracranial and gastrointestinal hemorrhage, hematuria and hemothorax have been reported in 2% of patients treated with BRUKINSA monotherapy. Bleeding events of any grade, including purpura and petechiae, occurred in 50% of patients treated with BRUKINSA monotherapy.

Bleeding events have occurred in patients with and without concomitant antiplatelet or anticoagulation therapy. Co-administration of BRUKINSA with antiplatelet or anticoagulant medications may further increase the risk of hemorrhage.

Monitor for signs and symptoms of bleeding. Discontinue BRUKINSA if intracranial hemorrhage of any grade occurs. Consider the benefit-risk of withholding BRUKINSA for 3-7 days pre- and post-surgery depending upon the type of surgery and the risk of bleeding.

Infections

Fatal and serious infections (including bacterial, viral, or fungal) and opportunistic infections have occurred in patients with hematological malignancies treated with BRUKINSA monotherapy. Grade 3 or higher infections occurred in 23% of patients treated with BRUKINSA monotherapy. The most common Grade 3 or higher infection was pneumonia. Infections due to hepatitis B virus (HBV) reactivation have occurred.

Consider prophylaxis for herpes simplex virus, pneumocystis jiroveci pneumonia and other infections according to standard of care in patients who are at increased risk for infections. Monitor and evaluate patients for fever or other signs and symptoms of infection and treat appropriately.

Cytopenias

Grade 3 or 4 cytopenias, including neutropenia (27%), thrombocytopenia (10%), and anemia (8%) based on laboratory measurements, were reported in patients treated with BRUKINSA monotherapy.

Monitor complete blood counts during treatment and treat using growth factor or transfusions, as needed.

Second Primary Malignancies

Second primary malignancies, including non-skin carcinoma, have occurred in 9% of patients treated with BRUKINSA monotherapy. The most frequent second primary malignancy was skin cancer (basal cell carcinoma and squamous cell carcinoma of skin), reported in 6% of patients. Advise patients to use sun protection.

Cardiac Arrhythmias

Atrial fibrillation and atrial flutter have occurred in 2% of patients treated with BRUKINSA monotherapy. Patients with cardiac risk factors, hypertension, and acute infections may be at increased risk. Grade 3 or higher events were reported in 0.6% of patients treated with BRUKINSA monotherapy. Monitor signs and symptoms for atrial fibrillation and atrial flutter and manage as appropriate.

Embryo-Fetal Toxicity

Based on findings in animals, BRUKINSA can cause fetal harm when administered to a pregnant woman. Administration of zanubrutinib to pregnant rats during the period of organogenesis caused embryo-fetal toxicity, including malformations at exposures that were 5 times higher than those reported in patients at the recommended dose of 160 mg twice daily. Advise women to avoid becoming pregnant while taking BRUKINSA and for at least 1 week after the last dose. Advise men to avoid fathering a child during treatment and for at least 1 week after the last dose. If this drug is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to a fetus.

Adverse Reactions

The most common adverse reactions in > 10% of patients who received BRUKINSA were neutrophil count decreased (53%), platelet count decreased (39%), upper respiratory tract infection (38%), white blood cell count decreased (30%), hemoglobin decreased (29%), rash (25%), bruising (23%), diarrhea (20%), cough (20%), musculoskeletal pain (19%), pneumonia (18%), urinary tract infection (13%), hematuria (12%), fatigue (11%), constipation (11%), and hemorrhage (10%). The most frequent serious adverse reactions were pneumonia (11%) and hemorrhage (5%).

Of the 118 patients with MCL treated with BRUKINSA, 8 (7%) patients discontinued treatment due to adverse reactions in the trials. The most frequent adverse reaction leading to treatment discontinuation was pneumonia (3.4%). One (0.8%) patient experienced an adverse reaction leading to dose reduction (hepatitis B).

Drug Interactions

CYP3A Inhibitors: When BRUKINSA is co-administered with a strong CYP3A inhibitor, reduce BRUKINSA dose to 80 mg once daily. For co-administration with a moderate CYP3A inhibitor, reduce BRUKINSA dose to 80 mg twice daily.

CYP3A Inducers: Avoid co-administration with moderate or strong CYP3A inducers.

Specific Populations

Hepatic Impairment: The recommended dose of BRUKINSA for patients with severe hepatic impairment is 80 mg orally twice daily.

INDICATION

BRUKINSA is a kinase inhibitor indicated for the treatment of adult patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.

This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

About Tislelizumab

Tislelizumab (BGB-A317) is a humanized IgG4 anti–PD-1 monoclonal antibody specifically designed to minimize binding to FcγR on macrophages. In pre-clinical studies, binding to FcγR on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells. Tislelizumab is the first drug from BeiGene’s immuno-oncology biologics program and is being developed internationally as a monotherapy and in combination with other therapies for the treatment of a broad array of both solid tumor and hematologic cancers.

Tislelizumab is approved by the China National Medical Products Administration as a treatment for patients with classical Hodgkin’s lymphoma who received at least two prior therapies and for patients with locally advanced or metastatic urothelial carcinoma (UC) with PD-L1 high expression whose disease progressed during or following platinum-containing chemotherapy or within 12 months of neoadjuvant or adjuvant treatment with platinum-containing chemotherapy. Additionally, the Center for Drug Evaluation (CDE) of the China National Medical Products Administration (NMPA) has accepted a supplemental new drug application (sNDA) of BeiGene’s anti-PD-1 antibody tislelizumab in combination with two chemotherapy regimens for first-line treatment of patients with advanced squamous non-small cell lung cancer (NSCLC).

Currently, 15 potentially registration-enabling clinical trials are being conducted in China and globally, including 11 Phase 3 trials and four pivotal Phase 2 trials.

Tislelizumab is not approved for use outside of China.

AUTO1 in ALL
As of the data cut-off date of May 13, 2020, 19 patients had received AUTO1. AUTO1 was well tolerated, with no patients experiencing ≥ Grade 3 CRS. Three patients (16%) with high leukemia burden (>50% blasts) experienced Grade 3 neurotoxicity that resolved swiftly with the application of steroids. Of the 19 patients, 16 (84%) achieved MRD-negative CR. Two out of 16 patients received a transplant while in remission and CD19-negative relapse occurred in 3 (16%) patients. Durability of remissions is encouraging. Event Free Survival (EFS) and Overall Survival (OS) at 6 months are 62% and 72% respectively in all patients, and 76% and 92% respectively in the 13 patients treated with the closed (commercial) process. Median EFS and OS has not been reached, at a median follow up of 12.2 months (range up to 24.4 months).

"I am very encouraged by the tolerable safety profile and high level of sustained CRs we have observed with AUTO1 in the ALLCAR19 study that was achieved without subsequent stem cell transplant," said Dr. Claire Roddie, Consultant Hematologist, UCL Cancer Institute and University College London Hospital.

"Approximately 60% of adult ALL patients relapse or are refractory to first line therapy and there continues to exist a high unmet need," said Dr. Michael Bishop, MD, Professor of Medicine and Director of the Cellular Therapy Program at University of Chicago Medicine. "AUTO1 is a novel CD19 CAR T candidate with a compelling activity and safety profile and has the potential to change standard of care as a curative therapy for r/r ALL."

"The data update on AUTO1 presented at this year’s EHA (Free EHA Whitepaper) meeting show an encouraging durability of response without subsequent stem cell transplant and confirm the positive safety profile," said Dr. Christian Itin, chairman and chief executive officer of Autolus. "We have started enrolment of patients with r/r aALL in our pivotal Phase 1b/2 AUTO1-AL1 study."

AUTO3 in DLBCL
Dr. Wendy Osborne presented ALEXANDER Phase 1/2 clinical trial data for AUTO3. This data is consistent with our update on May 29, 2020, with a data cut-off date of April 27, 2020.

"These data are very encouraging, in terms of safety and tolerability, with a high level of clinical activity," said Dr. Wendy Osborne, Consultant Hematologist, Freeman Hospital, Newcastle upon Tyne Hospitals NHS Foundation Trust. "We are looking forward to enrolling additional patients in the outpatient cohort."

Dr. Wendy Osborne of Newcastle upon Tyne Hospitals NHS Foundation Trust also discusses AUTO3 data during the American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting in this video – courtesy of the Lymphoma Hub.
