  1. Initiation follows positive results from cohort 6 of phase 1b COSMIC-021 trial

    –  CONTACT-02 is the second of three phase 3 pivotal trials that are part of a clinical collaboration with Roche –

    Exelixis, Inc. (NASDAQ:EXEL) today announced the initiation of CONTACT-02, a global phase 3 pivotal trial of cabozantinib (CABOMETYX®) in combination with atezolizumab (TECENTRIQ®) in patients with metastatic castration-resistant prostate cancer (CRPC) who have been previously treated with one novel hormonal therapy.

    Initiation follows positive results from cohort 6 of phase 1b COSMIC-021 trial

    –  CONTACT-02 is the second of three phase 3 pivotal trials that are part of a clinical collaboration with Roche –

    Exelixis, Inc. (NASDAQ:EXEL) today announced the initiation of CONTACT-02, a global phase 3 pivotal trial of cabozantinib (CABOMETYX®) in combination with atezolizumab (TECENTRIQ®) in patients with metastatic castration-resistant prostate cancer (CRPC) who have been previously treated with one novel hormonal therapy. CONTACT-02 is part of a clinical trial collaboration between Exelixis and Roche that includes two additional phase 3 pivotal trials – CONTACT-01 in patients with metastatic non-small cell lung cancer (NSCLC) who have been previously treated with an immune checkpoint inhibitor and platinum-containing chemotherapy, which was initiated in June, and the planned CONTACT-03 trial in patients with metastatic renal cell carcinoma (RCC) who previously received an immune checkpoint inhibitor.

    "As many patients with advanced, castration-resistant prostate cancer who have progressed on a novel hormonal therapy wish to avoid or delay chemotherapy, more treatment options are needed," said Gisela Schwab, M.D., President, Product Development and Medical Affairs and Chief Medical Officer, Exelixis. "We are encouraged by the positive early stage results for the combination of cabozantinib and atezolizumab seen for prostate cancer patients in cohort 6 of the COSMIC-021 trial, and we are pleased to begin this pivotal trial that will further evaluate how the combination may improve outcomes for these patients as part of our ongoing partnership with Roche."

    CONTACT-02 is a global, multicenter, randomized, phase 3, open-label study that plans to enroll approximately 580 patients at 250 sites. Patients will be randomized 1:1 to the experimental arm of cabozantinib in combination with atezolizumab and the control arm of a second novel hormonal therapy (either abiraterone and prednisone or enzalutamide). The co-primary endpoints of the trial are progression-free survival and overall survival. Additional endpoints include objective response rate, prostate-specific antigen response rate and duration of response. The trial is sponsored by Exelixis and co-funded by Roche, Ipsen and Takeda Pharmaceutical Company Limited.

    The design of CONTACT-02 was informed by results from the ongoing COSMIC-021 trial — a phase 1b study of cabozantinib and atezolizumab in multiple advanced solid tumors including NSCLC, CRPC and RCC. Initial results from cohort 6 were presented at the 2020 American Society of Clinical Oncology's Genitourinary Cancers Symposium. The interim analysis was updated with additional biomarker results and presented at the 2020 American Society of Clinical Oncology Virtual Scientific Program.

    More information about CONTACT-02 is available at ClinicalTrials.gov (NCT04446117).

    About CRPC

    According to the American Cancer Society, in 2020, approximately 192,000 new cases of prostate cancer will be diagnosed and 33,000 people will die from the disease.1 Prostate cancer that has spread beyond the prostate and does not respond to androgen-suppression therapies — a common treatment for prostate cancer — is known as metastatic CRPC.2 Researchers estimate that in 2020, 43,000 men will be diagnosed with metastatic CRPC, which has a median survival of less than two years.3,4,5

  3. Initiation follows positive results from cohort 7 of phase 1b COSMIC-021 trial

    CONTACT-01 is the first of three phase 3 pivotal trials that are part of a previously announced clinical collaboration with Roche –

    Exelixis, Inc. (NASDAQ:EXEL) today announced the initiation of CONTACT-01, a global phase 3 pivotal trial of cabozantinib (CABOMETYX®) in combination with atezolizumab (TECENTRIQ®) in patients with metastatic non-small cell lung cancer (NSCLC) who have been previously treated with an immune checkpoint inhibitor (ICI) and platinum-containing chemotherapy.

    Initiation follows positive results from cohort 7 of phase 1b COSMIC-021 trial

    CONTACT-01 is the first of three phase 3 pivotal trials that are part of a previously announced clinical collaboration with Roche –

    Exelixis, Inc. (NASDAQ:EXEL) today announced the initiation of CONTACT-01, a global phase 3 pivotal trial of cabozantinib (CABOMETYX®) in combination with atezolizumab (TECENTRIQ®) in patients with metastatic non-small cell lung cancer (NSCLC) who have been previously treated with an immune checkpoint inhibitor (ICI) and platinum-containing chemotherapy. Two additional phase 3 pivotal trials in metastatic castration-resistant prostate cancer (CRPC; CONTACT-02) and renal cell carcinoma (RCC; CONTACT-03) are planned as part of the clinical trial collaboration between Exelixis and Roche.

    "Survival rates for patients with metastatic non-small cell lung cancer are low, and since more than half of these patients are diagnosed at an advanced stage, the patient community is in need of new treatment options, especially for those who progress following immunotherapy and chemotherapy," said Gisela Schwab, M.D., President, Product Development and Medical Affairs and Chief Medical Officer, Exelixis. "We were pleased to see the positive results from cohort 7 of the COSMIC-021 trial further supporting the growing body of preclinical and clinical evidence that cabozantinib may promote a more immune-permissive environment potentially resulting in additive or synergistic effects with immune checkpoint inhibitors such as atezolizumab. We look forward to forthcoming findings for the combination in this disease in CONTACT-01, as well as in other difficult-to-treat cancers in planned phase 3 studies."

    Results from the ongoing COSMIC-021 trial — a phase 1b study of cabozantinib and atezolizumab in multiple advanced solid tumors including NSCLC, CRPC and RCC — informed the design of this phase 3 pivotal trial. Initial results from the COSMIC-021 cohort of patients with advanced NSCLC who progressed after treatment with an ICI were presented at the 2020 American Society of Clinical Oncology Virtual Scientific Program.

    CONTACT-01 is a global, multicenter, randomized, phase 3, open-label study that aims to enroll approximately 350 patients. Patients will be randomized 1:1 to the experimental arm of cabozantinib in combination with atezolizumab and the control arm of docetaxel. The primary endpoint of the trial is overall survival. Secondary endpoints include progression-free survival, objective response rate and duration of response. The trial is sponsored by Roche and co-funded by Exelixis.

    About NSCLC

    Lung cancer is the second most common type of cancer in the U.S., with more than 220,000 new cases expected to be diagnosed in 2020.1 The disease is the leading cause of cancer-related mortality in both men and women, causing 25% of all cancer-related deaths.1 The majority (84%) of lung cancer cases are NSCLC, which mainly comprise adenocarcinoma, squamous cell carcinoma and large cell carcinoma.1 The five-year survival rate for patients with NSCLC is 24%, but that rate falls to just 6% for those with advanced or metastatic disease.2 More than half of lung cancer cases are diagnosed at an advanced stage, and more options are needed for these patients.3

    About CABOMETYX® (cabozantinib)

    In the U.S., CABOMETYX tablets are approved for the treatment of patients with advanced RCC and for the treatment of patients with HCC who have been previously treated with sorafenib. CABOMETYX tablets have also received regulatory approvals in the European Union and additional countries and regions worldwide.

    CABOMETYX in combination with atezolizumab is not indicated for previously treated metastatic non-small cell lung cancer.

    Osteonecrosis of the Jaw (ONJ): ONJ occurred in <1% of CABOMETYX patients. ONJ can manifest as jaw pain, osteomyelitis, osteitis, bone erosion, tooth or periodontal infection, toothache, gingival ulceration or erosion, persistent jaw pain, or slow healing of the mouth or jaw after dental surgery. Perform an oral examination prior to CABOMETYX initiation and periodically during treatment. Advise patients regarding good oral hygiene practices. Withhold CABOMETYX for at least 3 weeks prior to scheduled dental surgery or invasive dental procedures, if possible. Withhold CABOMETYX for development of ONJ until complete resolution.

    Impaired Wound Healing: Wound complications occurred with CABOMETYX. Withhold CABOMETYX for at least 3 weeks prior to elective surgery. Do not administer CABOMETYX for at least 2 weeks after major surgery and until adequate wound healing is observed. The safety of resumption of CABOMETYX after resolution of wound healing complications has not been established.

    Reversible Posterior Leukoencephalopathy Syndrome (RPLS): RPLS, a syndrome of subcortical vasogenic edema diagnosed by characteristic findings on MRI, can occur with CABOMETYX. Evaluate for RPLS in patients presenting with seizures, headache, visual disturbances, confusion, or altered mental function. Discontinue CABOMETYX in patients who develop RPLS.

    Embryo-Fetal Toxicity: CABOMETYX can cause fetal harm. Advise pregnant women and females of reproductive potential of the potential risk to a fetus. Verify the pregnancy status of females of reproductive potential prior to initiating CABOMETYX and advise them to use effective contraception during treatment and for 4 months after the last dose.

    Adverse Reactions

    The most commonly reported (≥25%) adverse reactions are: diarrhea, fatigue, decreased appetite, PPE, nausea, hypertension, and vomiting.

    Phase 3 pivotal trials planned for advanced non-small cell lung cancer and metastatic castration-resistant prostate cancer

    Exelixis, Inc. (NASDAQ:EXEL) today announced phase 1b clinical trial results for the combination of cabozantinib (CABOMETYX®) and atezolizumab (TECENTRIQ®) in patients with locally advanced or metastatic solid tumors. The data from three expansion cohorts of the COSMIC-021 trial will be presented during the 2020 American Society of Clinical Oncology Virtual Scientific Program (ASCO20). Results from the non-small cell lung cancer (NSCLC) and the metastatic castration-resistant prostate cancer (CRPC) cohorts will be presented as posters, and results from the urothelial carcinoma (UC) cohort will be presented as a poster discussion; all three presentations will be available on demand for ASCO20 registrants beginning Friday, May 29 at 8:00 a.m. ET.

    NSCLC Expansion Cohort (abstract 9610):

    Initial results from the NSCLC expansion cohort (cohort 7) will be presented by Joel Neal, M.D., Ph.D., Associate Professor of Medicine – Oncology at the Stanford University School of Medicine, one of the lead trial investigators. The analysis included 30 patients who had received prior therapy with immune checkpoint inhibitors, and 87% of patients had received prior chemotherapy. Fifty percent of patients received the cabozantinib and atezolizumab combination as their second line of therapy and 50% as their third line of therapy. At the time of enrollment in the study, the best response to prior immune checkpoint inhibitor therapy was a partial response in 3 (10%) patients, stable disease in 7 (23%) patients, progressive disease in 14 (47%) patients and unknown in 5 (17%) patients.

    At a median follow-up of 12.1 months, the investigator-assessed confirmed objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST) v. 1.1, the trial's primary endpoint, was 27%, and the disease control rate was 83%. Median progression-free survival (PFS) was 4.2 months (95% confidence interval [CI] 2.7–7 months) with 22 events (73%), and median duration of response for all responding patients was 5.7 months.

    "Cabozantinib, in combination with immune checkpoint inhibitors, has now demonstrated promise in multiple difficult to treat tumor types," said Dr. Sumanta Pal, Clinical Professor, City of Hope, the principal investigator for the COSMIC-021 study. "The findings from the three COSMIC-021 cohorts presented at ASCO20 add to the growing body of evidence of potential synergistic effects with cabozantinib and immune checkpoint inhibitors. We are particularly encouraged by the new data emerging from the NSCLC cohort which showed a 27% confirmed overall response rate, including three patients with primary refractory disease to checkpoint inhibition. Further evaluation of cabozantinib and atezolizumab in patients with advanced tumor types, including immune checkpoint inhibitor-pretreated NSCLC, and forms of prostate and urothelial cancers, is warranted."

    The most common treatment-related adverse events (AEs) were diarrhea (53%), fatigue (37%), nausea (30%), decreased appetite (23%), palmar-plantar erythrodysesthesia (20%) and vomiting (20%). One patient experienced grade 5 pneumonitis that was related to atezolizumab, and one patient (3%) discontinued due to treatment-related AEs not associated with disease progression.

    "We are encouraged by these promising findings in patients with non-small cell lung cancer who had been previously treated with immune checkpoint inhibitor therapy, along with other COSMIC-021 results presented at ASCO20," said Gisela Schwab, M.D., President, Product Development and Medical Affairs and Chief Medical Officer, Exelixis. "The efficacy data and favorable safety profiles seen in the three cohorts suggest the combination of cabozantinib and atezolizumab offers promise for patients with advanced, difficult-to-treat tumor types. These findings and additional data from these cohorts will inform the design of future studies, including planned phase 3 pivotal trials for the combination of cabozantinib and atezolizumab in advanced or metastatic NSCLC and CRPC."

    UC Expansion Cohort (abstract 5013):

    Initial results from the UC expansion cohort (cohort 2) will be presented by Dr. Pal. The analysis included 30 patients who had been previously treated with platinum-containing chemotherapy, with a median follow-up of 19.7 months. The investigator-assessed ORR per RECIST v. 1.1 was 27%, with two complete responses; disease control rate was 63%. Median duration of response was not yet reached, and the longest ongoing response was 15.6 months. Median PFS was 5.4 months. Preliminary data did not suggest an association between PD-L1 expression and tumor response.

    The most common treatment-related AEs were asthenia (37%), diarrhea (27%), decreased appetite (23%), increased transaminases (23%) and mucosal inflammation (20%). No discontinuations due to treatment-related AEs occurred.

    CRPC Expansion Cohort (abstract 5564):

    An interim analysis from the metastatic CRPC expansion cohort (cohort 6) was previously presented at the 2020 American Society of Clinical Oncology's Genitourinary Cancers Symposium and was now updated with additional biomarker results that will be presented by Neeraj Agarwal, M.D., Professor, Huntsman Cancer Center, University of Utah, and an investigator of the trial. This analysis of 44 patients who had been previously treated with enzalutamide and/or abiraterone found an ORR per RECIST v. 1.1 of 32% and a disease control rate of 80% at a median follow up of 15.8 months. Preliminary data from the analysis did not suggest an association between PD-L1 expression and antitumor activity, suggesting patients with or without PD-L1 may respond to treatment with the combination of cabozantinib plus atezolizumab. Comparison of baseline and circulating immune cell counts after 21 days showed a total increase in circulating T cells (CTLs) and a decrease in immunosuppressive cells. Subpopulations of CTLs also increased with the largest accumulation observed for prolonged activated CTLs.

    Additional safety and efficacy findings from this analysis were previously presented at the 2020 American Society of Clinical Oncology's Genitourinary Cancers Symposium.

    Based on regulatory feedback from the U.S. Food & Drug Administration (FDA), and if supported by the clinical data, Exelixis intends to file with the FDA for accelerated approval in a metastatic CRPC indication as early as 2021.

    More information about COSMIC-021 is available at ClinicalTrials.gov (NCT03170960).

    About the COSMIC-021 Study

    COSMIC-021 is a multicenter, phase 1b, open-label study that is divided into two parts: a dose-escalation phase and an expansion cohort phase. The dose-escalation phase was designed to enroll patients either with advanced renal cell carcinoma (RCC) with or without prior systemic therapy or with inoperable, locally advanced, metastatic or recurrent UC, (including renal, pelvis, ureter, urinary bladder and urethra) after prior platinum-based therapy. Ultimately, all 12 patients enrolled in this stage of the trial were patients with advanced RCC. The dose-escalation phase of the study determined the optimal dose of cabozantinib to be 40 mg daily when given in combination with atezolizumab (1200 mg infusion once every 3 weeks). These results were presented at the European Society for Medical Oncology 2018 Congress.

    In the expansion phase, the trial is enrolling 24 cohorts in 12 tumor types: RCC, UC, NSCLC, CRPC, hepatocellular carcinoma (HCC), triple-negative breast cancer, epithelial ovarian cancer, endometrial cancer, gastric or gastroesophageal junction adenocarcinoma, colorectal adenocarcinoma, head and neck cancer, and differentiated thyroid cancer. Up to 1,720 patients may enroll in this phase of the trial: each expansion cohort will initially enroll approximately 30 patients, and up to 10 cohorts may further expand enrollment resulting in up to 1,000 patients across such potential additional expansion cohorts.

    Four of the cohorts are exploratory: three are enrolling approximately 30 patients each with advanced UC, CRPC or NSCLC to be treated with cabozantinib as a single-agent, and one is enrolling approximately 10 patients with advanced CRPC to be treated with single-agent atezolizumab. Exploratory cohorts have the option to be expanded up to 80 patients (cabozantinib) and 30 patients (atezolizumab) total.

    Exelixis is the study sponsor of COSMIC-021. Ipsen has opted in to participate in the trial and is contributing to the funding for this study under the terms of the companies' collaboration agreement. Roche is providing atezolizumab for the trial.

    About NSCLC

    Lung cancer is the second most common type of cancer in the U.S., with more than 220,000 new cases expected to be diagnosed in 2020.1 The disease is the leading cause of cancer-related mortality in both men and women, causing 25% of all cancer-related deaths.1 The majority (84%) of lung cancer cases are NSCLC, which mainly comprise adenocarcinoma, squamous cell carcinoma and large cell carcinoma.1 The five-year survival rate for patients with NSCLC is 24%, but that rate falls to just 6% for those with advanced or metastatic disease.2 More than half of lung cancer cases are diagnosed at an advanced stage,3 and more options are needed for these patients.

    About UC

    Urothelial cancers encompass carcinomas of the bladder, ureter and renal pelvis at a ratio of 50:3:1, respectively.4 Bladder cancer occurs mainly in older people, with 90 percent of patients aged 55 or older.5 With more than 81,000 new cases expected to be diagnosed in 2020, bladder cancer accounts for about five percent of all new cases of cancer in the U.S. each year.6 It is the fourth most common cancer in men.7

    About CRPC

    According to the American Cancer Society, in 2020, approximately 192,000 new cases of prostate cancer will be diagnosed and 33,000 people will die from the disease.7 Prostate cancer that has spread beyond the prostate and does not respond to androgen-suppression therapies — a common treatment for prostate cancer — is known as metastatic CRPC.8 Researchers estimate that in 2020, 43,000 people with prostate cancer will progress to metastatic CRPC, which has a median survival of less than two years.9,10,11

    About CABOMETYX® (cabozantinib)

    In the U.S., CABOMETYX tablets are approved for the treatment of patients with advanced RCC and for the treatment of patients with HCC who have been previously treated with sorafenib. CABOMETYX tablets have also received regulatory approvals in the European Union and additional countries and regions worldwide. In 2016, Exelixis granted Ipsen exclusive rights for the commercialization and further clinical development of cabozantinib outside of the United States and Japan. In 2017, Exelixis granted exclusive rights to Takeda Pharmaceutical Company Limited for the commercialization and further clinical development of cabozantinib for all future indications in Japan.
