Corvus Pharmaceuticals, Inc. (Nasdaq: CRVS), a clinical-stage biopharmaceutical company, confirmed today that it completed an End-of-Phase/Pre-Phase 3 meeting with FDA on its plans to initiate a Phase 3 registrational clinical trial of soquelitinib (formerly CPI-818), the Company’s ITK inhibitor product candidate, in relapsed peripheral T cell lymphoma (PTCL).
Plans to initiate soquelitinib potentially registrational Phase 3 clinical trial in Q1 2024
Company to host conference call and webcast tomorrow at 8:30 a.m. ET / 5:30 a.m. PT
BURLINGAME, Calif., Sept. 06, 2023 (GLOBE NEWSWIRE) -- Corvus Pharmaceuticals, Inc, (Nasdaq: CRVS), a clinical-stage biopharmaceutical company, confirmed today that it completed an End-of-Phase/Pre-Phase 3 meeting with FDA on its plans to initiate a Phase 3 registrational clinical trial of soquelitinib (formerly CPI-818), the Company’s ITK inhibitor product candidate, in relapsed peripheral T cell lymphoma (PTCL).
“We are pleased with the outcome of our End-of-Phase/Pre-Phase 3 meeting with FDA, allowing us to advance ITK inhibition with soquelitinib into a potentially registrational clinical trial for patients with relapsed peripheral T cell lymphoma,” said Richard A. Miller, co-founder, president and chief executive officer of Corvus. “We appreciate the FDA’s input and their confirmation on the key aspects of the trial design, including sample size, dosing, eligibility, comparator arm and endpoints. We are now focused on finalizing the study protocol, qualifying trial sites and completing other standard steps required to initiate the trial. Based on current timelines, we anticipate that we can initiate the trial in the first quarter of 2024.”
The soquelitinib Phase 3 potentially registrational clinical trial is designed to enroll a total of 150 patients with relapsed PTCL that have received three or fewer prior therapies. Patients will be randomized 1:1 to soquelitinib 200 mg two-times a day or standard of care chemotherapy. The primary endpoint will be progression-free survival. Secondary endpoints will include objective response rate and overall survival. The Company is recruiting U.S. and international investigators and anticipates that leading academic and private medical centers with significant experience in lymphoma research will participate in the trial, including a principal investigator who has conducted other Phase 3 clinical trials in T cell lymphoma and authored many peer-reviewed articles on lymphomas.
Dr. Miller added, “Soquelitinib’s proposed mechanism of action, based on selective ITK inhibition, represents a platform opportunity with the potential to address a wide range of indications beyond hematologic cancers, including solid tumors and autoimmune/allergic diseases.”
Data highlighting the potential of selective inhibition of ITK to potentially enhance anti-tumor immune response to hematologic and solid tumors and provide a novel potential approach to cancer immunotherapy were recently published online as a preprint at bioRxiv.org. In addition, data demonstrating soquelitinib’s anti-tumor activity in patients with T cell lymphoma (TCL) and its therapeutic potential in Th2 and Th17-mediated autoimmune and allergic diseases was presented in a poster at the 64th American Society of Hematology (ASH) Annual Meeting & Exposition, which took place in December 2022. The preprint and ASH poster presentation are available on the Publications and Presentations page of the Corvus website.

About Corvus Pharmaceuticals
Corvus Pharmaceuticals is a clinical-stage biopharmaceutical company pioneering the development of ITK inhibition as a new approach to immunotherapy for a broad range of cancer and immune diseases. The Company’s lead product candidate is soquelitinib, an investigational, oral, small molecule drug that selectively inhibits ITK and is planned to enter a Phase 3 potentially registrational clinical trial for patients with relapsed peripheral T cell lymphoma. Its other clinical-stage candidates are being developed for a variety of cancer indications. For more information, visit www.corvuspharma.com.
About Soquelitinib
Soquelitinib (CPI-818) is an investigational small molecule drug given orally designed to selectively inhibit ITK (interleukin-2-inducible T cell kinase), an enzyme that is expressed predominantly in T cells and plays a role in T cell and natural killer (NK) cell immune function. The immunologic effects of soquelitinib lead to what is known as Th1 skewing and is made possible by the high selectivity of soquelitinib for ITK. Research on soquelitinib’s mechanism of action suggests that it has the potential to control differentiation of normal T helper cells and enhance immune responses to tumors by augmenting the generation of cytotoxic killer T cells and the production of cytokines that inhibit cancer cell survival. Soquelitinib has been shown to prevent T cell exhaustion, a major limitation of current immunotherapy and CAR-T therapies. Optimal doses of soquelitinib have been shown to affect T cell differentiation and induce the generation of Th1 helper cells while blocking the development of both Th2 and Th17 cells and production of their secreted cytokines. Th1 T cells are required for immunity to tumors, viral infections and other infectious diseases. Th2 and Th17 helper T cells are involved in the pathogenesis of many autoimmune and allergic diseases. The Company believes the inhibition of specific molecular targets in T cells may be of therapeutic benefit for patients with cancers, including solid tumors, and in patients with autoimmune and allergic diseases. Based on interim results from a Phase 1/1b clinical trial in patients with refractory T cell lymphomas, which demonstrated tumor responses in very advanced, refractory, difficult to treat T cell malignancies, the Company plans to initiate a potentially registrational Phase 3 clinical trial of soquelitinib in patients with relapsed peripheral T cell lymphoma (PTCL).
About Peripheral T Cell Lymphoma
Peripheral T cell lymphoma (PTCL) is a heterogeneous group of malignancies accounting for about 10% of non-Hodgkin’s lymphomas (NHL) in Western populations, reaching 20% to 25% of NHL in some parts of Asia and South America. The most common subtypes are PTCL-not otherwise specified (PTCL-NOS) and T follicular helper cell lymphoma. Initial therapy for these diseases is typically combination chemotherapy, however, approximately 75% of patients either do not respond or relapse within the first two years. Patients in relapse are treated with various chemotherapy agents but have poor overall outcomes with median progression-free survival in the 3 to 4 month range and overall median survival of 6 to 12 months. There are no approved drugs in relapsed PTCL based on randomized trials.
PTCL is a disease of mature helper T cells that express ITK, often containing numerous genetic mutations and frequently associated with viral infection. Most often the malignant cells of PTCL express a Th2 phenotype.
