Study Summary

This trial will assess the safety and effectiveness of a drug, navtemadlin, to treat advanced or recurrent endometrial cancer. It will compare two doses of the drug to a placebo to determine the best dose.

Who is the study for?
This trial is for patients with advanced or recurrent endometrial cancer who responded well to a specific chemo. They must have normal TP53 genes, good performance status (ECOG 0-1), and proper blood, liver, and kidney function. It's not for those with recent major bleeding, organ transplants, certain other cancers, recent experimental therapies or immune/cytokine therapy.Check my eligibility
What is being tested?
The study tests navtemadlin as a maintenance treatment after chemotherapy success in two parts: first to find the best dose comparing two levels of navtemadlin against observation; second to compare that dose's effectiveness and safety against a placebo.See study design
What are the potential side effects?
While specific side effects of navtemadlin are not listed here, common ones may include fatigue, nausea, risk of infection due to low blood counts from bone marrow suppression; liver or kidney issues could also be monitored.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Part 1: To determine the navtemadlin Phase 3 dose
Part 2: To compare progression-free (PFS) survival by independent review committee (IRC) between navtemadlin and placebo
Secondary outcome measures
Part 1: To evaluate the treatment effect of navtemadlin on PFS by IRC and investigator assessment
Part 2: To evaluate the treatment effect of navtemadlin on the time to first subsequent treatment (TFST)
Parts 1 and 2: To determine the pharmacokinetic (PK) profile of navtemadlin

Frequently Asked Questions

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

Are there any opportunities to partake in this experiment?

"Affirmative. Clinicaltrials.gov demonstrates that this clinical trial, which was initially posted on July 17th 2023 is still actively recruiting participants. A total of 268 subjects must be enrolled from 4 separate medical centres in order for the trial to continue its research."

Answered by AI

What key goals are being sought through this research effort?

"Across this 12 month study, the primary objective is to compare progression-free (PFS) survival between navtemadlin and placebo as determined by independent review committee (IRC). The secondary goals are to assess the pharmacokinetic profile of navtemadlin; determine time of maximum plasma concentration (Tmax); and evaluate treatment effect on disease control rate (DCR), with best response from prior chemotherapy being partial response."

Answered by AI

What is the aggregate number of participants enrolled in this medical experiment?

"Affirmative. Clinicaltrials.gov states that this research project is presently in the process of recruiting participants, commencing on July 17th 2023 and most recently updated on August 3rd 2023. In total, 268 patients must be sourced from 4 distinct medical facilities."
