What is the purpose of this trial?

This trial tests the effectiveness of a new drug combination for certain types of ovarian and endometrial cancer. The goal is to determine if adding relacorilant, an experimental treatment, to other cancer therapies can benefit patients whose cancers have resisted or returned after previous treatments. Participants may qualify if they have ovarian cancer unresponsive to platinum-based treatments or endometrial cancer that has returned or spread. The trial evaluates safety and effectiveness, offering an option if previous treatments have failed. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

Do I need to stop my current medications to join the trial?

The trial protocol does not specify if you need to stop taking your current medications. However, you cannot take certain treatments like corticosteroids, hormonal anticancer therapies, or anticoagulants close to the start of the study. It's best to discuss your specific medications with the trial team.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Studies have shown that the combination of relacorilant, nab-paclitaxel, and bevacizumab is generally well-tolerated by patients. Research indicates that adding relacorilant to nab-paclitaxel extends the time patients live without their cancer worsening. Importantly, the side effects were manageable and similar to those expected with these cancer treatments.

When relacorilant is used with nab-paclitaxel, it has been found to be safe and improved patients' tolerance to the treatment, resulting in fewer or less severe side effects. While detailed data on side effects for the combination of relacorilant, nab-paclitaxel, and bevacizumab is lacking, the safety of each drug individually is well-documented and acceptable in other studies.

This trial is in Phase 2, indicating that the treatment has already demonstrated some safety in earlier testing. Researchers are now assessing its effectiveness and confirming its safety in a larger group. This phase helps ensure the treatment is safe enough for wider use if it continues to show positive results. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for ovarian cancer because they combine relacorilant with nab-paclitaxel and bevacizumab, offering a potentially powerful new approach. Unlike standard chemotherapy treatments like carboplatin and paclitaxel, which typically target cancer cells broadly, this combination specifically leverages relacorilant's ability to modulate the body's stress hormone receptors. This mechanism could enhance the effectiveness of nab-paclitaxel and bevacizumab, which are already known to disrupt cancer cell growth and blood supply. In addition, relacorilant's unique action might help overcome resistance in platinum-resistant ovarian cancer, a significant challenge with current treatments.

What evidence suggests that this trial's treatments could be effective for ovarian cancer?

Research has shown that combining relacorilant with nab-paclitaxel and bevacizumab may help treat ovarian cancer. In this trial, Arm A evaluates this combination in patients with platinum-resistant ovarian cancer, while Arm B assesses it in patients with platinum-sensitive ovarian cancer who have progressed during treatment with a polymerase inhibitor. One study found that using relacorilant with nab-paclitaxel helped patients live longer without their cancer worsening, particularly for those previously treated with certain other cancer drugs. Arm C of this trial explores the combination of relacorilant and nab-paclitaxel in patients with previously-treated advanced, recurrent, or metastatic endometrial cancer. Another study reported that relacorilant and nab-paclitaxel significantly improved survival for patients with ovarian cancer unresponsive to platinum-based treatments. These findings suggest that this treatment could improve outcomes for gynecological cancers. ^{1 2 3 6 7}

Published Research Related to This Trial

In a study of 164 patients with recurrent ovarian cancer, the combination of bevacizumab (BEV) with paclitaxel and carboplatin significantly improved progression-free survival (PFS), overall survival (OS), and objective response rate (ORR) compared to the control group receiving only paclitaxel and carboplatin.

The experimental group experienced fewer adverse reactions, such as allergies and gastrointestinal issues, and showed a significant improvement in quality of life after treatment, indicating that BEV combined with paclitaxel is both effective and safer for patients.

Therapeutic effect of bevacizumab combined with paclitaxel and carboplatin on recurrent ovarian cancer. Cong, J., Liu, R., Hou, J., et al.[2020]

Bevacizumab, a monoclonal antibody targeting vascular endothelial growth factor-A, has shown response rates of 16-21% as a single-agent treatment for recurrent ovarian cancer, indicating its efficacy in this context.

In combination with standard chemotherapy for advanced ovarian cancer, bevacizumab significantly improves progression-free survival, although it does not enhance overall survival; the main safety concern is hypertension, with rare but serious risks including gastrointestinal perforation and toxicity to the kidneys and central nervous system.

Bevacizumab and ovarian cancer. Garcia, A., Singh, H.[2021]

Bevacizumab has been shown to be effective in managing epithelial ovarian cancer, particularly when combined with cytotoxic chemotherapy, as indicated by phase III trial data that demonstrate improved progression-free survival.

There is a compelling argument for using bevacizumab as a single agent in patients with platinum-resistant ovarian cancer, suggesting a more rational and potentially cost-effective approach to treatment.

The use of bevacizumab in the management of ovarian cancer: an argument for single-agent rather than combination therapy. Markman, M.[2020]

In a phase III trial involving 484 patients with platinum-sensitive recurrent ovarian cancer, the combination of bevacizumab (BV) with gemcitabine and carboplatin (GC) significantly improved progression-free survival (PFS) compared to GC alone, with a median PFS of 12.4 months versus 8.4 months.

The addition of BV also led to a higher objective response rate (78.5% vs. 57.4%) and longer duration of response (10.4 months vs. 7.4 months), although it was associated with increased rates of grade 3 or higher hypertension and proteinuria, indicating a need for monitoring these side effects.

In a phase 3 trial involving 682 patients with recurrent ovarian cancer, the combination of carboplatin-pegylated liposomal doxorubicin and bevacizumab showed a median progression-free survival of 13.3 months, significantly longer than the 11.6 months observed with the standard carboplatin-gemcitabine-bevacizumab regimen (p=0.012).

The safety profile was comparable between the two treatment groups, with hypertension and neutropenia being the most common severe adverse events; however, treatment-related deaths were rare, occurring in less than 1% of patients in both groups.

Bevacizumab and platinum-based combinations for recurrent ovarian cancer: a randomised, open-label, phase 3 trial. Pfisterer, J., Shannon, CM., Baumann, K., et al.[2022]

Bevacizumab, a monoclonal antibody that targets VEGF, has shown anticancer activity in ovarian cancer, both as a single agent and in combination with chemotherapy, leading to its FDA approval for several cancers.

While bevacizumab can be effective, there is a significant risk of gastrointestinal perforation, especially in patients who have been heavily pretreated, which is an important consideration for patients and healthcare providers.
