Official title

A Phase Ⅰ/Ⅱ Study of TTI-622 in Combination With Pegylated Liposomal Doxorubicin in Patients With Platinum-Resistant Ovarian Cancer

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Pegylated liposomal doxorubicin (PLD), a type of chemotherapy, is a standard treatment option for patients with platinum-resistant ovarian cancer. However, despite being consider a standard treatment option, the clinical benefit of chemotherapy alone for these patients is small. Historically, response rates for PLD monotherapy have only ranged from 12 to 35% with a high likelihood of recurrence within months after treatment initiation. Although bevacizumab (BEV), an anti-new-vascular growth monoclonal antibody has been approved by FDA to combine with standard chemotherapy (e.g., PLD) for platinum-resistant recurrent ovarian cancer, there are still many restrictions or contraindications preventing certain women from receiving bevacizumab's combination treatment. The goal of this study is to improve upon the activity of PLD in a safe manner to provide a more effective therapeutic option for this group of patients. The purpose of this study is to assess maplirpacept (PF-07901801) administered in combination with PLD in patients with platinum-resistant ovarian cancer and for whom PLD is a reasonable treatment option. The first portion of the study will evaluate the safety of increasing dose levels of maplirpacept (PF-07901801) in combination with PLD at 40 mg/m2 in patients with platinum-resistant EOC (epithelial ovarian cancer). This is a group of cancer, including ovarian, peritoneal, and fallopian tube malignancy. The aim of the first portion of the study is to establish a combination regimen for further assessment in a dose expansion cohort. The study will consist of a 28-day screening period to ensure participants are qualified for the study treatment plan. During the treatment period, patients will receive maplirpacept (PF-07901801) in combination with PLD in 28-day cycles until their disease progresses or unacceptable toxicity develops. There will be a long-term follow-up period in this study to assess overall survival (length of time since start of treatment patients are alive).
