Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase 1/2, first-in-human, open-label, dose escalation and dose-expansion study of E-602, administered alone and in combination with cemiplimab.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This study is being conducted to evaluate the safety, tolerability, PK, pharmacodynamics, and antitumor activity of E-602 in subjects with advanced cancers.

Phase 1 of the study consists of dose escalation cohorts of E-602 as a monotherapy and in combination with cemiplimab. Dose escalation will utilize a modified 3+3 design. Any Phase 1 cohort may be backfilled, up to a total of 15 subjects to obtain additional safety, PK, and pharmacodynamic data at a particular dose level. Phase 1 will treat subjects with melanoma, ovarian cancer, non-small cell lung cancer (NSCLC), colorectal cancer, pancreatic cancer, breast cancer, gastric/esophagogastric junction (EGJ) cancer, head and neck cancer, or urothelial cancer. The safety and pharmacodynamic data will be evaluated to identify the maximum tolerated dose and recommended Phase 2 dose level for E-602 as monotherapy and in combination with cemiplimab.

Phase 2 consists of dose-expansion disease cohorts in subjects with 3 types of advanced tumors: melanoma, NSCLC, and a third type to be determined (ovarian, colorectal, pancreatic, breast, gastric/EGJ, head and neck, or urothelial) based on available data. Phase 2 includes cohorts of E-602 as monotherapy and E-602 in combination with cemiplimab. For each cohort in Phase 2, Simon's minimax 2-stage design will be used.

The study is seeking to enroll a total of up to 273 subjects (up to 87 in Phase 1 and up to 186 in Phase 2). Subjects will participate in the study for about 16 months.

Intervention Model

SEQUENTIAL

Phase 1: The study uses a modified 3+3 design with 5 planned dose levels of E-602 as monotherapy and 2 planned dose levels of E-602 in combination with cemiplimab. Phase 2: Consists of dose-expansion and will use the recommended Phase 2 dose level for E-602 as monotherapy and in combination with cemiplimab.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Subjects with advanced or relapsed/refractory melanoma, ovarian cancer, NSCLC, colorectal cancer, pancreatic cancer, breast cancer, gastric/esophagogastric junction (EGJ) cancer, head and neck cancer, or urothelial cancer who have failed prior therapies.

a. Subjects with melanoma, NSCLC, head and neck cancer, urothelial cancer, or mMSI-H or dMMR colorectal cancer must have had prior anti-PD-(L)1 pathway therapy and been deemed resistant (had progression on therapy or within 3 months of discontinuation of therapy).
2. Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
3. Subject has disease that is measurable by Response Evaluation Criteria in Solid Tumors (RECIST) v.1.1.
4. Adequate bone marrow, coagulation, renal function, and liver function as determined by laboratory tests

Exclusion Criteria

1. For cohorts receiving E-602 and cemiplimab combination therapy:

1. Prior moderate or severe hypersensitivity to cemiplimab or its formulation
2. History of severe (≥ Grade 3) autoimmune complications or discontinuation due to toxicity following treatment with an anti-PD-(L)1 pathway therapy as a monotherapy, with the exception of asymptomatic Grade 3 elevations in lipase and/or amylase not associated with clinical manifestations of pancreatitis.
