Study Details

Study Description

Brief Summary

This is a Phase 1 open label sequential dose escalation and cohort expansion study evaluating the safety, tolerability and preliminary clinical activity of COM701 as monotherapy and in combination with nivolumab.

Detailed Description

This Phase 1 study evaluates the safety, tolerability, Pharmacokinetics (PK) and preliminary clinical activity of COM701 an inhibitor of poliovirus receptor related immunoglobulin domain containing (PVRIG) as monotherapy and in combination with nivolumab in subjects with advanced solid tumors. Cohort expansion will be explored evaluating COM701 monotherapy and in combination with nivolumab in subjects with the following select tumor types (Non-Small cell lung cancer (NSCLC), Ovarian, Breast (including Triple negative breast cancer (TNBC) and endometrial cancer. Other tumor types such as CRC-MSS, CRC-KRAS mutant will be enrolled based on emerging clinical activity data.

Arms and Interventions

ArmIntervention/Treatment
Experimental: P1a Arm A (Monotherapy Dose Escalation).

COM701 monotherapy sequential dose escalation administered IV every 3 weeks and a Cohort IV every 4 weeks. Up to 8 dose escalation cohorts may be evaluated until a maximum tolerated dose or recommended phase 2 dose is identified.

Drug: COM701

Experimental: P1a Arm B (Combination Dose Escalation).

COM701 sequential dose escalation administered IV every 3 weeks in combination with Opdivo (Nivolumab) 360mg administered IV every 3 weeks and COM701 administered IV every 4 weeks in combination with Opdivo (Nivolumab) 480mg administered IV every 4 weeks.

Drug: COM701 with Opdivo (Nivolumab).
COM701 in combination with Opdivo (Nivolumab).

Experimental: P1a Arm A (Monotherapy Expansion).

COM701 monotherapy administered IV every 4 weeks. Cohort expansion in subjects with the following select tumor types (NSCLC, Breast, Ovarian, Endometrial and Colorectal cancer).

Drug: COM701
COM701 monotherapy.

Experimental: P1b (Combination Cohort Dose Expansion).

COM701 administered IV every 4 weeks in combination with Opdivo (Nivolumab) 480 mg administered IV every 4 weeks. Cohort expansion in subjects with the following select tumor types (Breast, Ovarian, Endometrial and Colorectal cancer).

Drug: COM701 with Opdivo (Nivolumab).
COM701 in combination with Opdivo (Nivolumab).

Outcome Measures

Primary Outcome Measures

  1. Incidence of subjects with Adverse Events (AEs) as per CTCAE v4.03 and Dose-Limiting Toxicities (DLTs). [DLT evaluation window in the 1st cycle (21 or 28 days).]

    To evaluate the safety profile of COM701 monotherapy and in combination with nivolumab.

  2. Determine the maximum tolerated dose (MTD) and/or the recommended dose for expansion (RDFE) (COM701 monotherapy and in combination with nivolumab). [Approximately 2 year.]

Secondary Outcome Measures

  1. Incidence of subjects with Anti-COM701 antibody. [Approximately 2 years.]

    Immunogenicity of COM701 monotherapy and in combination with nivolumab.

  2. Overall Response Rate as per RECIST v1.1 [Approximately 2 years.]

    Preliminary antitumor activity of COM701 in combination with nivolumab.

Key Inclusion Criteria:
  • Subject has Eastern Cooperative Oncology Group (ECOG) performance status 0-1.

  • Subjects who received prior immune-stimulatory antitumor agents, such as anti-PD-1, anti-PD-L1, anti-CTLA-4, OX-40, CD137, etc. are eligible.

Select Tumor Types (COM701 monotherapy cohort expansion; COM701 in combination with nivolumab):

  • Breast cancer (TNBC): Histologically confirmed incurable, advanced estrogen receptor-, progesterone receptor-, and human epidermal growth factor receptor 2 (HER2)-negative (triple-negative) adenocarcinoma of the breast, as defined by the American Society of Clinical Oncology-College of American Pathologists (ASCO-CAP) guidelines. Disease recurrence or progression during or after at least one systemic treatment that included an anthracycline and/or a taxane in the neoadjuvant, adjuvant, or metastatic setting. Subjects must have progressed after a poly ADP-ribose polymerase (PARP) inhibitor for patients with deleterious or suspected deleterious germline breast cancer susceptibility gene (BRCA) mutated metastatic breast cancer.

  • Ovarian cancer: Disease recurrence or progression during or after prior therapy that included: surgical resection, platinum agent, PARP inhibitor (for subjects with deleterious or suspected deleterious germline BRCA-mutated advanced ovarian cancer or as a maintenance therapy for subjects who have had complete or partial response to platinum-based therapy). P1b COM701 + nivolumab expansion cohort, COM701 monotherapy expansion cohort.

  • NSCLC: Documented stage IIIB or IV or recurrent NSCLC, Disease recurrence or progression during or after prior treatment that included: platinum agent, targeted therapy such as a TKI (if with biopsy-confirmed cytogenetic mutation eg EGFR, ROS, BRAF). COM701 monotherapy expansion cohort.
