What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores a new combination of drugs, pembrolizumab and lenvatinib, to treat high-grade serous ovarian cancer. Pembrolizumab aids the immune system in attacking cancer cells, while lenvatinib inhibits enzymes that cancer cells require for growth. Together, these drugs might control the disease more effectively. Women with a confirmed diagnosis of high-grade serous ovarian, peritoneal, or fallopian tube cancer that has not responded to platinum-based treatments may be suitable for this study. As a Phase 2 trial, the research focuses on measuring 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, it mentions that participants should not have received certain cancer therapies or live vaccines recently, and should not be on high doses of steroids or immunosuppressive therapy. 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?

Research has shown that using pembrolizumab and lenvatinib together is generally safe for patients. Studies have demonstrated this combination's effectiveness in treating ovarian cancer without unexpected safety issues. Some patients experienced side effects, but adjusting the lenvatinib dose often managed these. Overall, the treatment is considered well-tolerated, and many patients responded positively. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about pembrolizumab and lenvatinib for ovarian cancer because they offer a unique approach compared to standard treatments like chemotherapy and surgery. Pembrolizumab is an immunotherapy drug that helps the immune system recognize and attack cancer cells, while lenvatinib is a targeted therapy that inhibits the growth of blood vessels that supply the tumor. This combination may enhance the effectiveness of treatment by simultaneously boosting the immune response and cutting off the cancer's blood supply. Additionally, their different mechanisms of action could potentially lead to better outcomes and fewer side effects than traditional therapies.

What evidence suggests that pembrolizumab and lenvatinib might be an effective treatment for ovarian cancer?

Research has shown that using pembrolizumab and lenvatinib together can effectively treat ovarian cancer. In this trial, participants will receive both drugs, but the sequence of administration will differ between the two cohorts. This combination achieved a 37.5% overall response rate in patients with difficult-to-treat, platinum-resistant high-grade serous ovarian cancer. Another study found that 75.96% of patients were alive and had no disease progression after 6 months. In a similar group of patients, the response rate was 35%. These findings suggest that pembrolizumab and lenvatinib can help manage the disease and offer hope for patients facing this challenging condition. ^{1 3 4 6 7}

Beginning cycle 0, patients receive lenvatinib PO QD on days 1-21. Beginning cycle 1, patients also receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 35 cycles in the absence of disease progression or unacceptable toxicity.

Group II: Cohort A (pembrolizumab, lenvatinib) Experimental Treatment 2 Interventions

Beginning cycle 0, patients receive pembrolizumab IV over 30 minutes on day 1. Beginning cycle 1, patients also receive lenvatinib PO QD on days 1-21. Treatment repeats every 21 days for up to 35 cycles in the absence of disease progression or unacceptable toxicity.

Published Research Related to This Trial

In a study involving patients with recurrent platinum-resistant ovarian cancer, the combination of pembrolizumab, cisplatin, and gemcitabine resulted in an overall response rate of 60%, but the duration of response was relatively short at 4.9 months.

The addition of pembrolizumab did not show a significant benefit over chemotherapy alone, leading to the decision to close the trial for further accrual after an interim analysis indicated modest outcomes.

In a phase 2 study involving 54 patients with advanced endometrial cancer, the combination of lenvatinib and pembrolizumab resulted in a 39.6% objective response rate at week 24, indicating significant anti-tumor activity.

The treatment was generally well-tolerated, with serious adverse events occurring in 30% of patients, including one treatment-related death; however, the safety profile was consistent with previous studies of the individual drugs, except for a higher incidence of hypothyroidism.

In a study of 43 patients with recurrent endometrial cancer treated with lenvatinib and pembrolizumab, 84% experienced significant adverse events (AEs), with hypertension and weight loss being the most common.

Patients starting on a reduced dose of lenvatinib (10 mg or 14 mg) had significantly longer progression-free survival compared to those on the standard dose (20 mg), suggesting that dose optimization may improve treatment outcomes.
