What You Need to Know Before You Apply

What is the purpose of this trial?

This phase II/III trial studies how well trametinib works and compares it to standard treatment with either letrozole, tamoxifen, paclitaxel, pegylated liposomal doxorubicin, or topotecan in treating patients with low-grade ovarian cancer or peritoneal cavity cancer that has come back (recurrent), become worse (progressive), or spread to other parts of the body. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether trametinib is more effective than standard therapy in treating patients with ovarian or peritoneal cavity cancer.

Will I have to stop taking my current medications?

The trial requires that any hormonal therapy directed at the tumor be stopped at least one week before joining, and any other cancer treatments, including chemotherapy and radiation, must be stopped at least four weeks before joining. Herbal supplements are also not allowed during the study.

Is trametinib safe for use in humans?

Trametinib has been studied in various trials and is generally considered safe, with safety results aligning with its known profile. In one study, no serious adverse events led to withdrawal, and in another, some patients experienced severe treatment-related side effects, but these were managed with dose adjustments.12345

How is the drug trametinib unique for treating ovarian cancer?

Trametinib is unique for treating low-grade serous ovarian cancer because it targets the MEK1/2 proteins in the MAPK pathway, which is often altered in these tumors, and it has shown to significantly increase progression-free survival compared to standard treatments.16789

What data supports the effectiveness of the drug Trametinib for ovarian cancer?

Research shows that Trametinib, a MEK1/2 inhibitor, increases progression-free survival from 7.2 months to 13 months in women with recurrent low-grade serous ovarian cancer and boosts the overall response rate from 6% to 26%.16101112

Are You a Good Fit for This Trial?

This trial is for patients with recurrent or progressive low-grade ovarian cancer or peritoneal cavity cancer who have previously undergone at least one platinum-based chemotherapy. They must not have received certain inhibitor therapies, be able to swallow oral medication, and meet specific health criteria including organ function tests. Pregnant women, nursing mothers, and those with serious medical risks are excluded.

What Are the Treatments Tested in This Trial?

Interventions

  • Trametinib
Trial Overview The effectiveness of trametinib is being compared to standard treatments (letrozole, tamoxifen, paclitaxel, pegylated liposomal doxorubicin hydrochloride or topotecan) in this phase II/III trial. Trametinib aims to inhibit enzymes needed for tumor cell growth and its performance will be measured against existing therapies.

Published Research Related to This Trial

The pediatric oral solution of trametinib showed improved bioavailability compared to the tablet formulation, with significant increases in key pharmacokinetic measures such as Cmax and AUC, indicating it may be more effective in delivering the drug to patients.
The safety profile of the trametinib pediatric oral solution was consistent with existing data, with no serious adverse events leading to withdrawal from the study, suggesting it is a safe option for patients.

In a phase 3 trial involving 36 patients with untreated BRAF V600-mutant metastatic melanoma, the combination of spartalizumab, dabrafenib, and trametinib resulted in a high objective response rate of 78%, with 44% achieving complete responses.
While the treatment showed promising efficacy, 72% of patients experienced severe treatment-related adverse events, and 17% had to permanently discontinue the therapy due to these side effects, highlighting the need for careful monitoring and management of adverse effects.
