On June 28, 2021 Kite, a Gilead Company (Nasdaq: GILD), reported top-line results from the primary analysis of ZUMA-7, a randomized Phase 3 global, multicenter study showing superiority of Yescarta (axicabtagene ciloleucel) compared to standard of care (SOC) in second-line relapsed or refractory large B-cell lymphoma (LBCL) (Press release, Kite Pharma, JUN 28, 2021, View Source [SID1234584414]). With a median follow-up of two years, the study met the primary endpoint of event-free survival (EFS; hazard ratio 0.398, p <0.0001). The study also met the key secondary endpoint of objective response rate (ORR). The interim analysis of overall survival (OS) showed a trend favoring Yescarta; however, the data are immature at this time, and further analyses are planned for the future.

Overall survival measures deaths over time from any cause. Event-free survival is defined as time from randomization to disease progression, commencement of new lymphoma therapy, or death from any cause. ZUMA-7 was conducted under a Special Protocol Agreement (SPA) with the U.S. Food and Drug Administration (FDA) whereby the trial design, clinical endpoints and statistical analysis were agreed in advance with the Agency.

Safety results from the study were consistent with or lower than the known safety profile of Yescarta for the treatment of LBCL in the third-line setting. Six percent of patients experienced cytokine release syndrome (CRS) Grade 3 or higher, with a median onset of three days, and 21% experienced neurological events Grade 3 or higher. No new safety concerns were identified in this second-line setting.

"The top-line results of the randomized ZUMA-7 trial paint the picture of a potential paradigm shift in the treatment of large B-cell lymphoma," said Frederick L. Locke, MD, ZUMA-7 Lead Principal Investigator and Co-Leader of the Immuno-Oncology Program at Moffitt Cancer Center, Tampa, Florida. "The outcomes for patients relapsing after frontline chemotherapy in this study are dramatically improved with rapid referral (to a CAR T center) and a single infusion of axicabtagene ciloleucel as compared to chemotherapy and consolidative autologous transplant, the longstanding second-line standard of care."

ZUMA-7 evaluated an one-time infusion of the CAR T-cell therapy Yescarta compared to SOC in adult patients with relapsed or refractory LBCL. Standard of care for relapsed or refractory LBCL is a two-step process: immunochemotherapy is reintroduced, and if the patient responds and can tolerate further treatment, they move on to high-dose chemotherapy plus stem cell transplant.

"Yescarta has been instrumental in transforming outcomes for patients with third-line LBCL. Our goal has always been to bring the benefit of CAR T-cell therapy to more patients, earlier in their treatment, where the potential for benefit may be even greater," said Christi Shaw, Chief Executive Officer of Kite. "As the leader in cell therapy, Kite is honored to deliver this landmark study and would like to thank the patients, families, physicians and care teams around the world that made this possible."

ZUMA-7 was initiated in 2017 and enrolled 359 patients in 77 centers around the world. Results released today represent the longest follow-up time of any study in this setting with two years median follow-up. Patients enrolled in the study ranged in age from 22 to 81, with 30% of the patients 65 or older.

"Over 40 years ago, we learned the important role T-cells play in fighting cancer, and 20 years ago autologous stem cell transplant became an option to treat lymphoma. Today’s results show us the potential power of cell therapy for patients with lymphoma when used earlier, and instead of standard treatment options," said Frank Neumann, MD, PhD, Kite’s Global Head of Clinical Development.

Detailed results from ZUMA-7 will be submitted for presentation at a future medical congress, and Kite plans to initiate discussions with the U.S. Food and Drug Administration, European Medicines Agency and other global health authorities regarding submission of a supplemental Biologics License Application later this year to expand the currently approved indications for Yescarta. See About Yescarta section for current Yescarta approved indications. Yescarta has not been approved by any regulatory agency for the treatment of patients in the second-line setting similar to those in ZUMA-7.

About 40% of patients with LBCL will need second-line treatment, as their cancer will either relapse (return) or become refractory (not respond) to treatment.

About ZUMA-7 Study Design

ZUMA-7 is a randomized, open-label, global, multicenter, Phase 3 study evaluating the safety and efficacy of Yescarta versus current standard of care (SOC) for second-line therapy (platinum-based salvage combination chemotherapy regimen followed by high-dose therapy and autologous stem cell transplant in those who respond to salvage chemotherapy) in adult patients with relapsed or refractory (within or equal to 12 months of first-line therapy), large B-cell lymphoma (LBCL). In the study, 359 patients were randomized (1:1) to receive a single infusion of Yescarta or current SOC second-line therapy. The primary endpoint is event-free survival (EFS), defined as the time from randomization to the earliest date of disease progression per Lugano Classification (Cheson et al, 2014), commencement of new lymphoma therapy, or death from any cause as determined by blinded central review. Key secondary endpoints include objective response rate (ORR) and overall survival (OS). Other secondary endpoints include modified EFS, progression-free survival (PFS) and duration of response (DOR).

U.S. IMPORTANT SAFETY INFORMATION

BOXED WARNING: CYTOKINE RELEASE SYNDROME AND NEUROLOGIC TOXICITIES

Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving Yescarta. Do not administer Yescarta to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids.
Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving Yescarta, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with Yescarta. Provide supportive care and/or corticosteroids as needed.
Yescarta is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the Yescarta and Tecartus REMS Program.
CYTOKINE RELEASE SYNDROME (CRS), including fatal or life-threatening reactions, occurred. CRS occurred in 88% (224/254) of all patients with non-Hodgkin lymphoma (NHL), including Grade ≥3 in 10%. CRS occurred in 94% (101/108) of patients with large B-cell lymphoma (LBCL), including Grade ≥3 in 13%. Among patients with LBCL who died after receiving Yescarta, 4 had ongoing CRS events at the time of death. The median time to onset of CRS was 2 days (range: 1-12 days) and the median duration was 7 days (range: 2-58 days) for patients with LBCL. CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL), including Grade ≥3 in 8% (11/146). Among patients with iNHL who died after receiving Yescarta, 1 patient had an ongoing CRS event at the time of death. The median time to onset of CRS was 4 days (range: 1-20 days) and median duration was 6 days (range: 1-27 days) for patients with iNHL. Key manifestations of CRS (≥10%) in all patients combined included fever (80%), hypotension (38%), tachycardia (29%), hypoxia (21%), chills (21%), and headache (13%). Serious events that may be associated with CRS include cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), cardiac arrest, cardiac failure, renal insufficiency, capillary leak syndrome, hypotension, hypoxia, multi-organ failure and hemophagocytic lymphohistiocytosis/macrophage activation syndrome. In a subsequent cohort of LBCL patients, tocilizumab and/or corticosteroids were administered for ongoing Grade 1 events. CRS occurred in 93% (38/41) of these patients and 2% (1/41) had Grade 3 CRS, with no patients experiencing a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days). Key manifestations of CRS (>5%) included pyrexia, hypotension, chills, headache, nausea, tachycardia, C-reactive protein increased, fatigue, hypoxia, and vomiting. Ensure that 2 doses of tocilizumab are available prior to Yescarta infusion. Following infusion, monitor patients for signs and symptoms of CRS at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated.

NEUROLOGIC TOXICITIES that were fatal or life-threatening occurred. Neurologic toxicities occurred in 81% (206/254) of all patients with NHL receiving Yescarta, including Grade ≥3 in 26%. Neurologic toxicities occurred in 87% (94/108) of patients with LBCL, including Grade ≥3 in 31%. The median time to onset was 4 days (range: 1-43 days) and the median duration was 17 days for patients with LBCL. Neurologic toxicities occurred in 77% (112/146) of patients with iNHL, including Grade ≥3 in 21%. The median time to onset was 6 days (range: 1-79 days) and the median duration was 16 days for patients with iNHL. 98% of all neurologic toxicities in patients with LBCL and 99% of all neurologic toxicities in patients with iNHL occurred within the first 8 weeks of Yescarta infusion. Neurologic toxicities occurred within the first 7 days of infusion for 89% of affected patients with LBCL and 74% of affected patients with iNHL. The most common neurologic toxicities (≥10%) in all patients combined included encephalopathy (53%), headache (45%), tremor (31%), dizziness (20%), delirium (16%), aphasia (15%), and insomnia (11%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including leukoencephalopathy and seizures, as well as fatal and serious cases of cerebral edema, have occurred. In a subsequent cohort of LBCL patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41) of these patients and 20% (8/41) had Grade 3 neurologic toxicities with no patients experiencing a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1-93 days) with a median duration of 8 days (range: 1-144 days). The most common neurologic toxicities were consistent with the overall LBCL population treated with Yescarta. Following Yescarta infusion, monitor patients for signs and symptoms of neurologic toxicities at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter, and treat promptly.

REMS: Because of the risk of CRS and neurologic toxicities, Yescarta is available only through a restricted program called the Yescarta and Tecartus REMS Program which requires that: Healthcare facilities that dispense and administer Yescarta must be enrolled and comply with the REMS requirements and must have on-site, immediate access to a minimum of 2 doses of tocilizumab for each patient for infusion within 2 hours after Yescarta infusion, if needed for treatment of CRS. Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer Yescarta are trained about the management of CRS and neurologic toxicities. Further information is available at www.YescartaTecartusREMS.com or 1-844-454-KITE (5483).

HYPERSENSITIVITY REACTIONS: Allergic reactions, including serious hypersensitivity reactions or anaphylaxis, may occur with the infusion of Yescarta.

SERIOUS INFECTIONS: Severe or life-threatening infections occurred. Infections (all grades) occurred in 47% (119/254) of all patients with NHL. Grade ≥3 infections occurred in 19% of patients, Grade ≥3 infections with an unspecified pathogen occurred in 15%, bacterial infections in 5%, viral infections in 2%, and fungal infections in 1%. Yescarta should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after infusion and treat appropriately. Administer prophylactic anti-microbials according to local guidelines. Febrile neutropenia was observed in 40% of all patients with NHL and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated. In immunosuppressed patients, including those who have received Yescarta, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed. Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing.

PROLONGED CYTOPENIAS: Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and Yescarta infusion. Grade ≥3 cytopenias not resolved by Day 30 following Yescarta infusion occurred in 30% of all patients with NHL and included neutropenia (22%), thrombocytopenia (13%), and anemia (5%). Monitor blood counts after infusion.

HYPOGAMMAGLOBULINEMIA and B-cell aplasia can occur. Hypogammaglobulinemia occurred in 17% of all patients with NHL. Monitor immunoglobulin levels after treatment and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following Yescarta treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during Yescarta treatment, and until immune recovery following treatment.

SECONDARY MALIGNANCIES may develop. Monitor life-long for secondary malignancies. In the event that one occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing.

EFFECTS ON ABILITY TO DRIVE AND USE MACHINES: Due to the potential for neurologic events, including altered mental status or seizures, patients are at risk for altered or decreased consciousness or coordination in the 8 weeks following Yescarta infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period.

ADVERSE REACTIONS: The most common adverse reactions (incidence ≥20%) in patients with LBCL included CRS, fever, hypotension, encephalopathy, tachycardia, fatigue, headache, decreased appetite, chills, diarrhea, febrile neutropenia, infections with pathogen unspecified, nausea, hypoxia, tremor, cough, vomiting, dizziness, constipation, and cardiac arrhythmias. The most common non-laboratory adverse reactions (incidence ≥20%) in patients with iNHL included fever, CRS, hypotension, encephalopathy, fatigue, headache, infections with pathogen unspecified, tachycardia, febrile neutropenia, musculoskeletal pain, nausea, tremor, chills, diarrhea, constipation, decreased appetite, cough, vomiting, hypoxia, arrhythmia, and dizziness.

On July 28, 2021 Onconova Therapeutics, Inc. (NASDAQ: ONTX) ("Onconova"), a clinical-stage biopharmaceutical company focused on discovering and developing novel products for patients with cancer, reported an update on the investigator-initiated Phase 1/2a trial of oral rigosertib plus nivolumab in advanced metastatic KRAS mutated (KRAS+) non-small cell lung cancer (NSCLC) (Press release, Onconova, JUN 28, 2021, View Source [SID1234584413]). The clinical data to date provide preliminary evidence of potential anti-cancer activity of rigosertib-nivolumab combination therapy in advanced metastatic KRAS+ non-small cell lung cancer and show that the maximum tolerated dose of rigosertib in combination with nivolumab was not reached in the three cohorts of the trial’s dose-escalation phase. Patients enrolled in this trial have failed multiple lines of prior therapy and all have failed immune checkpoint inhibitors in various combinations.

The trial continues to recruit patients as part of the expansion phase at the highest dose of oral rigosertib defined in the current protocol. Based on the positive preliminary findings from the trial, a protocol amendment is being prepared that would allow for the evaluation of increased rigosertib doses in combination with the full dose of intravenous nivolumab, as recommended per its product label.

"The preliminary results from this Phase 1/2a trial are very encouraging and demonstrate the potential of rigosertib to address a critical unmet medical need by overcoming checkpoint inhibitor resistance in KRAS mutated lung adenocarcinoma," said Mark S. Gelder, M.D., Chief Medical Officer of Onconova. "The observation of preliminary evidence of efficacy in combination with acceptable safety of the doublet in this extremely challenging patient population provides a promising signal. This phase 1 study supports the preclinical observation in melanoma of the up regulation of crucial cell surface molecules by rigosertib which may synergize with immune checkpoint blockade, as recently published in Molecular Cancer, and strongly supports the continued clinical development of rigosertib-checkpoint inhibitor combination therapy. We look forward to the presentation of preliminary data at the upcoming 3rd Annual RAS Targeted Drug Development Summit taking place September 21-23, 2021, and at a future major medical meeting as the data mature."

Steven M. Fruchtman, M.D., President and Chief Executive Officer of Onconova, commented, "This Phase 1/2a trial is an important part of our investigator-initiated study program, which enables us to pursue opportunities to develop rigosertib in high-need KRAS mutated indications while maintaining our primary focus on our lead ON 123300 program. We are very pleased both with the safety and preliminary efficacy signal we have seen from the KRAS mutated NSCLC trial to date, considering the multiple lines of therapy many of these patients have previously failed, including checkpoint inhibitors in various combinations. We are supportive of the plan to expand dose-escalation of rigosertib to determine the optimal recommended Phase 2 dose of the combination; and are eagerly anticipating results of important correlative science that is part of the trial. We look forward to the trial’s continued progress and would like to thank the investigator and his team for conducting the trial, as well as the patients who are participating."

About the Investigator-initiated Phase 1/2a Trial
This Phase 1/2a trial is designed to evaluate the combination of rigosertib and nivolumab in advanced KRAS+ metastatic lung adenocarcinoma patients who have progressed on standard of care with anti-PD-1 monotherapy or anti-PD-1 in combination with chemotherapy. It includes a dose-escalating Phase 1 portion followed by a Phase 2a dose-expansion portion. Patients in the trial receive oral rigosertib twice daily on days 1-21, and intravenous nivolumab on days 1 and 15 of 28-day cycles. The primary endpoints of the trial are safety assessments and overall response rate. Secondary endpoints include progression free survival and overall survival. For more information on the trial, see ClinicalTrials.gov Identifier: NCT04263090.

The innovative approach behind TG4050 combines Transgene’s expertise in virus-based immunotherapies, NEC’s longstanding AI technologies and the commitment of prestigious cancer care centers in the United Kingdom, the European Union, and the United States.

THE FIRST UK PATIENT OF THE TRIAL EVALUATING THIS INDIVIDUALIZED CANCER IMMUNOTHERAPY HAS BEEN INCLUDED IN LIVERPOOL, UK, in a trial enrolling patients with squamous cell carcinoma of the head and neck.

The trial is led by the coordinating investigator Professor Christian Ottensmeier, Consultant Medical Oncologist at The Clatterbridge Cancer Centre and Professor of Immuno-Oncology at the University of Liverpool. In the UK, the trial is being conducted in Liverpool and in Southampton (at the Clatterbridge Cancer Centre NHS Foundation Trust, at Liverpool University Hospitals and at the University Hospital Southampton NHS Foundation Trust / University of Southampton).

Professor Christian Ottensmeier, M.D., Ph.D., coordinating investigator of the study, added: "We are pioneering the personalized cancer vaccine field. If successful, this technique could be a potentially game-changing development in the treatment of advanced head and neck cancers. We have spent the last 15 years working on the science behind this immunotherapy so it is very gratifying to be beginning clinical trials with the first patient being enrolled in the UK. Head and neck cancers are particularly complex to treat if they spread and cannot then be completely removed surgically. Personalized cancer vaccines are an extremely exciting development and, if successful, the same technique could also be applied to treat other forms of cancer." P R E S S R E L E A S E Page 2/4

Dr. Maud Brandely, M.D., Ph.D., Chief Medical Officer of Transgene, added: "We are delighted to start the clinical trial with our individualized myvac immunotherapy in the UK. We have been collaborating for several years with Professor Ottensmeier on this novel therapy to better target tumor cells and we are excited to see that our world-leading innovations are now reaching patients in different countries in Europe and in the USA. We are convinced that, together with leading scientists and clinicians, we will be able to demonstrate the value of our individualized approach against head and neck cancer and leverage these future results to target other solid tumors."

TG4050 IS A CANCER VACCINE FULLY CUSTOMIZED FOR EACH PATIENT COMBINING BEST-IN-CLASS THERAPEUTIC VACCINE RESEARCH AND CUTTING-EDGE AI TECHNOLOGY

Transgene’s highly innovative technology platform, myvac, enables the generation of a virusbased immunotherapy, which encodes patient-specific cancer cell mutations (neoantigens) identified and selected by NEC’s Neoantigen Prediction System (NPS), an advanced AI technology approach. TG4050 has been designed to target up to 30 patient-specific neoantigens.

With more than 20 years of AI expertise, NEC’s NPS has been trained using both proprietary and public immune databases. Preclinical work with the myvac technology platform has demonstrated that NEC’s AI-based tumor mutanome profiling tool accurately selects and prioritizes the most immunogenic neoantigens from each unique tumor1.

Transgene is using its expertise in viral genome engineering to incorporate the selected neoantigens into the DNA of the myvac-MVA viral vector.

The company has also set up a unique in-house Good Manufacturing Practices (GMP) unit dedicated to the manufacturing of the individualized batches of TG4050 that are needed for the ongoing Phase I clinical studies with this novel therapeutic vaccine.

FIRST DATA FROM TWO ONGOING CLINICAL TRIALS EXPECTED IN 4Q 2021
In a first Phase I trial, TG4050 is being administered to patients with HPV-negative head and neck cancer (NCT04183166). A personalized treatment is created for each patient after they complete surgery and while they receive an adjuvant therapy. Half of the participants receive their vaccine immediately after they complete their adjuvant treatment. The other half will be given TG4050 as an additional treatment at the time of recurrence of the disease. This randomized study is evaluating the treatment benefits of TG4050 in patients who have a high risk of relapse. Up to 30 patients will receive TG4050 in France, in the UK and in the USA.

The principal investigator of the trial is Prof. Christian Ottensmeier, M.D., Ph.D., Consultant Medical Oncologist at the Clatterbridge Cancer Centre and Professor of Immuno-Oncology at the University of Liverpool. In France, the clinical trial is being conducted at the IUCT-Oncopole, Toulouse, by Prof. Jean-Pierre Delord,M.D., Ph.D. and at Institut Curie, Paris, by Prof. Christophe Le Tourneau, M.D., Ph.D., Head of the Department of Drug Development and Innovation (D3i). In the USA, the trial is being led by Dr. Yujie Zhao, M.D., Ph.D., at the Mayo Clinic. 1 Mallone et al., "Performance of neoantigen prediction for the design of TG4050, a patient specific neoantigen cancer vaccine", AACR (Free AACR Whitepaper), June 2020 Page 3/4

In parallel, a second Phase I clinical trial of TG4050 is enrolling patients with ovarian cancer (NCT03839524). This second trial is including patients after surgery and first-line chemotherapy. Dr. Matthew Block, M.D., Ph.D., Consultant Medical Oncology, Consultant Immunology and Associate Professor of Oncology at the Mayo Clinic (USA) is the principal investigator of the trial; in France, the trial is being conducted by Prof. Christophe Le Tourneau at Institut Curie and by Dr. Alexandra Martinez, M.D., Associate Head of Surgical Department, at Toulouse-Oncopole. The first data from the two trials evaluating TG4050 are expected in 4Q 2021.

"We continue to build substantial value in Zentalis’ portfolio, driving toward approval of our differentiated cancer therapeutics to help patients worldwide," commented Dr. Anthony Sun, Chairman and Chief Executive Officer of Zentalis. "Based on our clinical results reported to date, the emerging clinical profiles of our candidates support the potential for best-in-class positioning for a range of tumor types addressing large patient populations, is use as a monotherapy or in combinations. In particular, we are excited about the compelling profile of ZN-c3, our WEE1 inhibitor, as it demonstrated additional, deepening and durable tumor responses as a monotherapy in heavily pretreated solid tumors. These promising data set the stage for the many upcoming planned trials – two of which have the potential to be registrational monotherapy studies in indications with significant unmet medical needs. We look forward to a productive second half of 2021, as we focus on delivering on our milestones across our entire pipeline."

ZN-c3: Oral WEE1 Inhibitor for Solid Tumors

Updates from our ongoing trials of ZN-c3 continue to support the potential for our WEE1 inhibitor, ZN-c3, to be both first-in-class and best-in-class. Since our last update at AACR (Free AACR Whitepaper) in April 2021, and as of the data cut-off date of May 15, 2021:

The 2 unconfirmed Partial Responses (PRs) reported at AACR (Free AACR Whitepaper) were confirmed, bringing the total number of confirmed PRs from our monotherapy trial from 3 to 5. Since AACR (Free AACR Whitepaper), an additional unconfirmed PR was reported in a patient with uterine serous carcinoma (USC), resulting in 3 out of 7 USC patients enrolled having responded to treatment. Overall, the objective response rate (ORR) in the USC population increased from 40% to 43% based on RECIST criteria.
Additionally, within the exceptional responder population in the Phase 1 monotherapy trial, we have observed a patient with an ongoing treatment duration of more than 8 months, with a deepening response of 65% to 69% tumor size decrease based on RECIST criteria.
Lower overall severe hematological adverse event rates – severe neutropenia adverse event rates decreased from 2.9% to 2.2% with an additional 11 patients enrolled since AACR (Free AACR Whitepaper) 2021.
Following an End-of-Phase 1 meeting, the U.S. Food and Drug Administration (FDA) concurred in principle with the proposal that ZN-c3 has the potential for an accelerated approval pathway based on the proposed global study design of a Phase 2 monotherapy trial in women with recurrent or persistent USC. The trial has initiated with multiple sites open.
Zentalis is planning to launch a biomarker-driven Phase 2 study pending FDA feedback. The tumor-agnostic trial will investigate ZN-c3 in patients with solid tumors that express the identified predictive biomarker, and is expected to initiate by year-end.
ZN-c3 has received orphan drug designation, and rare pediatric disease designation from the FDA for pediatric osteosarcoma. The Phase 1/2 trial of ZN-c3 in combination with chemotherapy in pediatric patients with osteosarcoma is expected to initiate in 3Q 2021. If ZN-c3 were to obtain approval for the designated indication, it could be eligible for a rare pediatric disease priority voucher upon approval.
Zentalis will also support two planned additional investigator-initiated trials: a trial with the Ivy Brain Center in glioblastoma multiforme (GBM) and a trial with immunotherapy with Dana Farber in triple negative breast cancer.
Zentalis’ China JV Zentera is advancing corresponding clinical trials in China with ZN-c3.

Based on the interim results from multiple ongoing trials, ZN-c5 has demonstrated the potential to support best-in-class tolerability in both monotherapy and combination settings, with strong clinical results observed. As of May 11, 2021, the following data were collected:

Monotherapy Trials (Expansion and Dose Escalation)

In total, 56 patients with 2 median prior lines of treatment were evaluated for safety and efficacy. Across all doses from 50 mg QD to 300 mg QD, the observed CBR was 33% and the ORR was 5%. ZN-c5 generated 2 PRs at the 150 mg and 300 mg doses. Adverse events (AEs) were found in less than 10% of the patients and there were no observed cases of bradycardia, visual disturbances, QTC or dizziness. Of note, treatment related diarrhea adverse event rate was 3.6%, with only grade 1 or 2 events observed. The Phase 2 monotherapy trial has been initiated and Zentalis may take multiple doses into this study.

An oral dose of 50 mg QD (n=16) demonstrated a CBR of 40%, with many patients in this dose cohort remaining on study drug and in the trial. Final determination of the monotherapy RP2D will occur following completion of this 50 mg QD dose cohort.
Combination Dose Escalation Trials with Pfizer’s CDK4/6 Palbociclib and Lilly’s CDK4 and 6 Abemaciclib

Tolerability data for ZN-c5 suggests it could be best-in-class in oral SERDS, making this candidate ideal for further evaluation in combination. The two separate trials will continue to enroll patients and the Company expects to report interim results in 1H 2022 from one or more of these trials.
Window of Opportunity Trial

The Window of Opportunity trial (n=35) demonstrated ER degradation across all doses tested.
ZN-d5: Highly Selective Oral BCL-2 Inhibitor for Hematologic Tumors

The Phase 1 monotherapy dose-escalation trial, initiated in 4Q 2020, has enrolled 14 patients with relapsed/refractory non-Hodgkin’s lymphoma (NHL) thus far in the fifth dose cohort. Additionally, no dose-limiting toxicities have been identified. Patients with acute myeloid leukemia will begin enrollment in 3Q 2021. Interim results from this Phase 1 trial are expected in 1H 2022.
ZN-e4: 3rd Generation Oral EGFR Inhibitor for Non-Small-Cell Lung Carcinoma

The Phase 1/2 dose-escalation trial in patients with advanced non-small cell lung cancer is ongoing with 26 patients (both osimertinib-naïve and experienced) enrolled to date. ZN-e4 has been well-tolerated at all doses as of the March 25, 2021 data cut-off, and clinical activity was identified at doses greater than 80 mg QD. Interim results from the Phase 1/2 trial are expected in 4Q 2021.
