Glycan Mediated Immune Regulation With a Bi-Sialidase Fusion Protein

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

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 camiplimab. 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
