Study Summary

This trial is testing a new cancer drug, TTI-622, in combination with an existing cancer drug, Pegylated liposomal doxorubicin. The trial will enroll approximately 50 patients in two phases to test different doses of the new drug.

Who is the study for?
This trial is for women with platinum-resistant ovarian cancer, including cancers of the ovary, fallopian tube, or peritoneum. Participants should have measurable disease and be in good physical condition (ECOG 0-1), with proper organ function. They must have progressed after standard treatments or cannot tolerate them. Women who've had more than four prior treatments for their resistant disease or those with certain heart conditions, CNS metastases, severe bleeding disorders, hypersensitivity to antibodies, or autoimmune diseases requiring intense treatment are excluded.Check my eligibility
What is being tested?
The study tests maplirpacept combined with Pegylated Liposomal Doxorubicin (PLD) chemotherapy in patients who haven't responded well to platinum-based therapies. Initially, it will determine the safest dose of maplirpacept to use alongside PLD by gradually increasing doses. Once a safe combination is found, more participants will receive this regimen over 28-day cycles until they experience significant side effects or their disease worsens.See study design
What are the potential side effects?
Potential side effects include reactions related to the immune system due to maplirpacept such as inflammation in various organs and infusion-related reactions; from PLD there may be fatigue, digestive issues like nausea and mouth sores; skin problems like hand-foot syndrome; low blood counts leading to increased infection risk; and potential heart toxicity.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Assess preliminary evidence of anti-tumor activity of (RP2D) maplirpacept (PF-07901801) in combination with 40 mg/m2 PLD (Phase 2 portion of study)
Evaluate DLTs (number) of each escalating dose level of cycle 1 of maplirpacept (PF-07901801) when administered in combination with 40 mg/m2 PLD in 28-day cycles in the Phase 1 escalation
Identify the Recommended Phase 2 Dose (RP2D) from the Phase 1 Escalation Phase

Secondary outcome measures
Assess Disease Control (DC) [CR+PR+SDS] of maplirpacept (PF-07901801) (RP2D) in combination with PLD 40mg/m2 in 28-day cycle in the Phase 2 expansion
Assess Duration of progression-free survival (PFS) of maplirpacept (PF-07901801) (RP2D) in combination with PLD 40mg/m2 in 28-day cycle in the Phase 2 expansion
Assess Duration of response (DOR) of maplirpacept (PF-07901801) (RP2D) in combination with PLD 40mg/m2 in 28-day cycle in the Phase 2 expansion

Trial Design

2Treatment groups
Experimental Treatment
Group I: Phase 2: Dose ExpansionExperimental Treatment2 Interventions
In the Phase 2 (dose expansion): maplirpacept (PF-07901801) will be administered with selected dose from the escalation phase by intravenous infusion on Days 1, 8, 15 and 22 in Cycle 1, and then on Days 1 and 15 in subsequent cycles in combination with Pegylated Liposomal Doxorubicin 40 mg/m2 by intravenous infusion on Day 1 of each 28-day cycle.
Group II: Phase 1: Dose EscalationExperimental Treatment2 Interventions
In the Phase 1 (dose escalation): Cycle 1 for dose levels 1 and 2, maplirpacept (PF-07901801) will be administered on Day 1, Day 8, Day 15 and Day 22 in combination with PLD on Day 1 of 28-day cycle. Beginning with Cycle 2 at dose levels 1 and 2, maplirpacept (PF-07901801) will be administered on Day 1 and Day 15 in combination with PLD on Day 1 of 28-day cycles. For Phase 1, dose level 3, maplirpacept (PF-07901801) will be administered on Day 1 and Day 15 in combination with PLD on Day 1 of 28-day cycles. Dose level 3 will be biweekly regimen from the start.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What are the overarching ambitions of this research endeavor?

"This medical trial will assess the efficacy of TTI-622 MTD or RP2D when combined with PLD over the course of 3 years. The primary outcome is to measure clinical activity, while secondary outcomes include duration of progression-free survival (PFS), time to progression and new metastases, and overall survival from study treatment initiation until death from any cause."
