What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new combination treatment for ovarian cancer that has not responded well to standard platinum-based chemotherapy. The study compares patient outcomes on a regimen of nab-paclitaxel (a type of chemotherapy) with and without relacorilant (an experimental treatment). Researchers aim to determine if the combination improves survival outcomes. The trial seeks participants with high-grade serous ovarian cancer who have tried up to three different cancer treatments and have previously received bevacizumab. As a Phase 3 trial, this study represents the final step before FDA approval, offering participants a chance to contribute to potentially groundbreaking treatment advancements.

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop all current medications, but you cannot take certain medications like strong CYP3A inhibitors or inducers, hormonal anticancer therapies within 7 days of the study, or systemic corticosteroids within 21 days of the study. It's best to discuss your current medications with the study team to see if any need to be adjusted.

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

Studies have shown that the combination of relacorilant and nab-paclitaxel is generally safe and well-tolerated. Research indicates that this combination has a known safety profile, having been tested before and found safe for use. Most patients can undergo the treatment without serious issues. While all medications can have side effects, previous studies found that the type and frequency of these effects were consistent with what is already known about these drugs.

For those considering joining this trial, it is reassuring that the treatment has undergone advanced testing stages, providing a strong understanding of its safety in humans. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for ovarian cancer?

Researchers are excited about the combination of relacorilant and nab-paclitaxel for ovarian cancer because it introduces a new approach by incorporating relacorilant, which targets the stress hormone receptor, potentially enhancing the effectiveness of chemotherapy. Unlike the standard chemotherapy treatments, which primarily focus on directly attacking cancer cells, relacorilant acts on the glucocorticoid receptor, possibly reducing the cancer's ability to resist treatment. This combination could improve outcomes by making cancer cells more susceptible to nab-paclitaxel. Additionally, using intermittent dosing of relacorilant with nab-paclitaxel may optimize treatment effectiveness and manage side effects better than current continuous chemotherapy regimens.

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

In this trial, one group of patients will receive a combination of relacorilant and nab-paclitaxel, while another group will receive nab-paclitaxel alone. Research has shown that adding relacorilant to nab-paclitaxel benefits patients with ovarian cancer. Studies have found that this combination reduces the risk of disease progression by 30%. It also extends patient survival and delays disease worsening during and after treatment. Patients with ovarian cancer unresponsive to platinum-based treatments have experienced significant improvements with this combination compared to nab-paclitaxel alone. The evidence supports that using relacorilant with nab-paclitaxel enhances outcomes for ovarian cancer patients. ^{1 6 7 8 9}

What Are the Treatments Tested in This Trial?

Interventions

• Nab-paclitaxel
• Relacorilant

Trial Overview The study tests relacorilant combined with nab-paclitaxel against nab-paclitaxel alone to see which is better at slowing down cancer progression. Patients will either receive relacorilant daily with intermittent doses of nab-paclitaxel or just regular doses of nab-paclitaxel.

How Is the Trial Designed?

Group I: Nab-paclitaxel 80 mg/m^2 with Relacorilant 150 mg Experimental Treatment 2 Interventions

Patients receive nab-paclitaxel 80 mg/m\^2 on Days 1, 8, and 15 of each 28-day cycle in combination with intermittent relacorilant (150 mg relacorilant once daily on the day before, the day of, and the day after nab-paclitaxel), administered orally under fed conditions. Relacorilant will not be administered on Cycle 1 Day -1.

Group II: Nab-paclitaxel 100 mg/m^2 Active Control 1 Intervention

Patients receive nab-paclitaxel 100 mg/m\^2 on Days 1, 8, and 15 of each 28-day cycle.

Published Research Related to This Trial

Nab-paclitaxel, a new formulation of paclitaxel, has shown a good safety and efficacy profile for treating metastatic breast cancer (MBC), although there is limited data on its impact on overall survival.

In combination with gemcitabine, nab-paclitaxel significantly improves survival in advanced pancreatic cancer (PC) and demonstrates better results in non-small-cell lung cancer (NSCLC) patients with squamous histology, highlighting its potential as a valuable treatment option.

Safety and efficacy evaluation of albumin-bound paclitaxel. Cecco, S., Aliberti, M., Baldo, P., et al.[2015]

NAB-paclitaxel at a dose of 125 mg/m² was well tolerated in patients with stage IV non-small-cell lung cancer, with no hypersensitivity reactions reported and a maximum-tolerated dose established without significant dose-limiting toxicities.

The treatment showed promising efficacy, with a 30% objective response rate, a median time to progression of 5 months, and a median overall survival of 11 months, indicating its potential as a viable single-agent therapy.

In a study of 47 patients with recurrent ovarian, peritoneal, or fallopian tube cancer, nab-paclitaxel demonstrated a significant objective response rate of 64%, indicating its efficacy in this patient population.

The treatment was associated with manageable toxicities, primarily neutropenia (24%) and neuropathy (9%), suggesting that nab-paclitaxel could be a viable option for patients with limited therapeutic choices.

Nab-PTX (Abraxane®) was administered to 31 breast cancer patients without any allergic reactions, indicating it is well tolerated, even in those with alcohol intolerance.

Among patients with locally advanced operable breast cancer, higher doses (260 mg/m²) resulted in a better response rate, with 10 out of 13 showing a partial response, suggesting its efficacy in treating advanced stages of the disease.

Nab-paclitaxel, a nanoparticle albumin-bound form of paclitaxel, is the first nanotechnology-based drug approved for cancer treatment, showing significant promise in breast and pancreatic cancers.

This innovative drug not only enhances the effectiveness and reduces the toxicity of traditional treatments but also demonstrates activity in cancers that typically do not respond to standard taxane therapies.
