About

This study is a Phase 1 and pharmacologic open-labeled dose-escalation trial using a "3+3" design, evaluating MM-151 at varying dose levels and frequencies, and subsequently in combination with irinotecan.

Full description

This study is a Phase 1 and pharmacologic open-labeled dose-escalation trial using a "3+3" design exploring weekly, bi-weekly, and tri-weekly dosing schedules. Successive MM-151 monotherapy cohorts of three or more patients will be treated at escalating doses until a maximum tolerated dose is identified, and subsequently in combination with irinotecan. The study consists of three parts as follows: MM-151 monotherapy dose escalation (Part 1); MM-151 monotherapy expansion cohort in cetuximab-refractory colorectal cancer (Part 2); MM-151 + irinotecan dose escalation (Part 3). It is expected that approximately 4 study sites will participate.

Enrollment: 112 patients

Sex: All

Ages: 18+ years old

• Patients must have histologically or cytologically confirmed advanced malignant solid tumor that has recurred or progressed following standard therapy, or that has not responded to standard therapy, or for which there is no standard therapy, or who are not candidates for standard therapy
• Patients must be > 18 years of age
• Patients of their legal representatives must be able to understand and sign an informed consent form

• Patients who are pregnant or lactating
• Patients with an active infection or with an unexplained fever > 38.5°C during screening visits or on the first scheduled day of dosing. (At the discretion of the investigator, patients with tumor fever may be enrolled.)
