FIRST Trial Summary

This trial is designed to compare the effectiveness of the current standard of care for ovarian cancer (SOC) with or without the addition of two new potential treatments, dostarlimab and niraparib.

Who is the study for?
This trial is for women aged 18+ with advanced non-mucinous epithelial ovarian cancer (Stage III/IV). They must be postmenopausal, surgically sterilized, or use contraception. Eligible participants should have an ECOG score of 0 or 1, can take oral meds, and have normal blood pressure or controlled hypertension. They cannot join if they've had recent major surgery, uncontrolled medical issues, immunodeficiency, certain past cancers within specific time frames, active hepatitis B/C or autoimmune diseases.Check my eligibility
What is being tested?
The study compares the effectiveness of platinum-based therapy combined with TSR-042 (dostarlimab) and niraparib versus standard chemotherapy in treating ovarian cancer. It's a global Phase 3 trial focusing on progression-free survival rates. Participants will receive standard care initially before being randomly assigned to either the new drug combination or continued standard treatment.See study design
What are the potential side effects?
Potential side effects include allergic reactions to medication components like paclitaxel and carboplatin; complications from conditions such as bowel obstruction; risks associated with immunosuppression; bleeding risks due to concurrent conditions; and general side effects from chemotherapy such as fatigue, nausea, hair loss.

Frequently Asked Questions

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

Could you please list other investigations that have included Niraparib?

"Niraparib is being researched in 112 different trials, with 14 of them being Phase 3. The locations for these studies are widespread, with 3147 sites running Niraparib trials."

Answered by AI

Are people still being recruited for this experiment?

"This particular study, which was last updated on 8/31/2022, is not looking for new patients at this time. However, based on the data from clinicaltrials.gov, there are 814 other open studies that are currently recruiting."

Answered by AI

In how many different medical institutions is this research project being conducted presently?

"Presently, this trial is recruiting patients from 74 sites. These locations include Dallas, Paoli, New Orleans as well other cities. It may be helpful to select the clinic nearest you to minimize travel if you enroll in the study."

Answered by AI

How many people are a part of this experiment?

"8/31/2022 was the date of the most recent update to this clinical trial's information on clinicaltrials.gov, which means that this study is no longer actively recruiting patients. There are presently 702 studies actively searching for participants with ovary cancer and 112 trials for Niraparib actively recruiting patients."

Answered by AI

Why was this research project undertaken?

"The aim of this trial, which will take place over the course of 5 years, is to assess PFS in PD-L1 positive patients. Additionally, investigators will also evaluate change from baseline in quality of life (QOL) scores as measured by the EORTC-QLQ Ovarian cancer Module OV28 assessment tool among PD-L1 positive participants. Lastly, researchers will track pCR rate and ORR among all participants enrolled in the study."

Answered by AI

What are the most severe side effects of taking Niraparib?

"Niraparib's safety is well supported by both efficacy data from Phase 3 trials as well as multiple rounds of safety testing, so it received a score of 3."

Answered by AI

What is the primary use of Niraparib?

"Niraparib is used as a treatment for primary peritoneal cancer. In addition, it can be administered to patients with advanced endometrial cancer who have progressed during or following platinum-based chemotherapy and those suffering from fallopian tube cancer."
