Corvus Announces Presentation of Preclinical Data on CPI-818, a First-in-class Covalent Inhibitor of ITK Targeting T-Cell Lymphomas
Company on track to submit Investigational New Drug application for CPI-818 in early 2019
Based on these data, Corvus plans to submit an Investigational New Drug (IND) application with the
“CPI-818 represents a novel approach to treating T-cell lymphomas, which are poorly controlled with existing therapies,” said
Data from in vitro studies of CPI-818, also presented at the meeting, have demonstrated:
- Cytotoxicity against several types of human and mouse T-cell lymphomas at concentrations that do not harm normal T-cells.
- Evidence of Th1 skewing in human and mouse lymphocytes, indicating that CPI-818 induced the differentiation of T-cells to cytotoxic (killer) T-cells, which is thought to be an important component of the immune system’s destruction of cancer cells.
CPI-818 is a small molecule drug given orally that has been shown to selectively inhibit ITK (interleukin-2-inducible T-cell kinase). It was developed to possess dual properties: to block malignant T-cell growth and modulate immune responses. ITK, an enzyme, is expressed predominantly in T-cells and plays a role in T-cell and natural killer (NK) cell lymphomas and leukemias, as well as in normal immune function. Interference with ITK signaling can modulate immune responses to various antigens. The inhibition of specific molecular targets in T-cells may be of therapeutic benefit for patients with T-cell lymphomas – similar to the role of Bruton’s tyrosine kinase (BTK) in B-cells. BTK is now an established target for treating various B-cell lymphomas, and two BTK inhibitors, ibrutinib and aclarabrutinib, have been approved by the U.S. Food and Drug Administration for lymphoma indications. CPI-818 has been evaluated in preclinical efficacy and safety studies.
About T-Cell Lymphomas
Human T-cell lymphomas are a heterogenous group of difficult-to-treat malignancies. They include peripheral T-cell lymphomas (PTCLs), cutaneous T-cell lymphomas (CTCLs), anaplastic large cell lymphomas, acute lymphocytic lymphoma (ALL), angioimmunoblastic T-cell lymphoma (AITL) and others.
According to the Leukemia and Lymphoma Society, PTCLs comprise a diverse group of aggressive diseases. They generally affect people older than 60 years, although they can occur anytime during adulthood. Common signs and symptoms include fatigue, a painless swelling in the neck, armpit or groin (due to an enlarged lymph node), night sweats, rash and weight loss. Median survival is about two years. Current treatment for PTCLs includes chemotherapy, but most patients relapse. CTCLs originate in the skin, with advanced stages defined by involvement of lymph nodes, peripheral blood and internal organs. CTCLs are treated with chemotherapy as well as topical therapies, including radiation to the skin.
Corvus Pharmaceuticals is a clinical-stage biopharmaceutical company focused on the development and commercialization of precisely targeted oncology therapies. Corvus’ lead product candidate, CPI-444, a small molecule inhibitor of the A2A receptor, is currently being evaluated in a multicenter Phase 1/1b clinical trial in patients with various solid tumors. This successive expansion cohort trial is examining the activity of CPI-444 both as a single agent and in combination with Genentech’s atezolizumab, an anti-PD-L1 antibody. Corvus is conducting the trial with Genentech, a member of the Roche Group, under a clinical trial collaboration the two companies entered into in October 2015. In May 2017, Corvus and Genentech expanded the collaboration and are now conducting a trial of CPI-444 and atezolizumab in patients with non-small cell lung cancer (NSCLC) who have failed prior therapies with anti-PD-(L)1 and platinum-based chemotherapy. Corvus is evaluating a second product candidate, CPI-006, a humanized monoclonal antibody directed against CD73, in a multicenter Phase 1/1b clinical trial in patients with various solid tumors.
