Summary

This is a First-in-Human Phase IA/IB/II open label dose escalation study of intravenous (IV) administration of ONC-392, a humanized anti-CTLA4 IgG1 monoclonal antibody, as single agent and in combination with pembrolizumab in participants with advanced or metastatic solid tumors and non-small cell lung cancers.

Detailed Description

Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4), also known as CD152 (cluster of differentiation 152), is a cell surface protein receptor that interacts with B7-1 (CD80) and B7-2 (CD86) to ensure proper function of regulatory T cells and protect host against autoinflammatory diseases. Anti-CTLA-4 monoclonal antibodies (mAbs) have demonstrated strong and broad cancer immunotherapeutic effects (CITE) in a variety of preclinical models and are used clinically both as monotherapy and as part of combination therapy with Nivolumab (anti-PD-1). However, CTLA-4 monotherapy has more immunotherapy-related adverse effects (irAEs) than anti-PD-1/PD-L1 therapy. In addition, the rate of severe irAE (Grades 3 and 4) reached 55% in melanoma patients receiving combination of Ipilimumab and Nivolumab. The strong irAEs further limit the doses tolerated by cancer patients. Nevertheless, combination with anti-PD-1 resulted in significantly improved response rates and patient survival in multiple types of cancer. Furthermore, anti-CTLA-4 antibodies induce long-lasting immunity in cancer patients. Therefore, CTLA-4 remains an important immunotherapy target, but major challenges remain in improving both safety and efficacy of anti-CTLA-4 mAbs.

ONC-392 is a highly selective, humanized monoclonal IgG1-kappa isotype antibody against CTLA-4. The parental clone was identified through in vivo screening in humanized CTLA-4 mouse model for high anti-tumor efficacy and low autoimmune toxicity. We have recently demonstrated that ONC-392 is dissociation from CTLA-4 under low pH to allow its escape from lysosomal degradation and recycle to cell surface. We have provided several lines of evidence for the notion that a pH-sensitive antibody ONC-392 is not only safer but also more effective in Treg depletion and tumor rejection than the Ipilimumab, which is pH-insensitive. First, by preserving CTLA-4 on the cell surface, Onc-392 leaves higher ligand density for better ADCC.

Second, Onc-392 is more efficient in Treg depletion in tumor microenvironment. Third, Onc-392 is significantly more potent in inducing rejection of large tumors.

The study consists of four parts:

(1) The Part A study is a dose-finding rapid titration, Phase I trial of ONC-392 as a single agent in patients with advanced or metastatic solid tumors with various histology. The aim of this trial is to define the recommended Phase II dose for ONC-392 monotherapy (RP2D-M). (2) The Part B study is a dose-finding phase with ONC-392 in combination with a standard dose of 200 mg pembrolizumab in patients with advanced or metastatic solid tumors.

(3) The Part C consists of different expansion arms.

1. Arm A: Pancreatic Cancer Cohort, ONC-392 monotherapy, will enroll advanced/metastatic pancreatic cancer patients who have progressive disease after first and second lines of systemic treatment.
2. Arm B: TNBC Cohort, ONC-392 monotherapy, will enroll advanced/metastatic TNBC patients who have progressive disease after prior systemic treatments, including checkpoint inhibitor immunotherapy.
3. Arm C: NSCLC Mono Cohort 1, ONC-392 monotherapy, will enroll advanced/metastatic NSCLC patients with EGFR or ALK mutations who have progressive disease after prior systemic treatments, including targeted therapy or checkpoint inhibitors.
