What side effects are associated with this type of intervention?

Common side effects of pembrolizumab, a PD-1 inhibitor used in cervical cancer treatment, include immune-related adverse events such as pneumonitis, colitis, hepatitis, endocrinopathies, and skin reactions. Olaparib, a PARP inhibitor, is associated with side effects like nausea, fatigue, anemia, leukopenia, and thrombocytopenia. Patients receiving these treatments may experience a combination of these adverse effects, and it is important to monitor and manage them under the guidance of a healthcare provider.

What prior FDA approvals exist?

Pembrolizumab, a PD-1 inhibitor, has been approved by the FDA for the treatment of advanced cervical cancer based on its demonstrated durable antitumor activity and manageable safety profile in clinical trials. Olaparib, a PARP inhibitor, is being studied in combination with pembrolizumab for advanced or recurrent cervical carcinoma, although specific FDA approval for this combination in cervical cancer has not been detailed. These treatments represent a shift towards targeted and immunotherapy approaches in managing advanced cervical cancer.

What other types of research exist?

Promising novel alternatives for cervical cancer treatment in 2024 include: 1) Nivolumab (another PD-1 inhibitor) combined with Ipilimumab (CTLA-4 inhibitor), which has shown efficacy in other cancers and is being explored in cervical cancer. 2) Tisotumab vedotin, an antibody-drug conjugate targeting tissue factor, which has demonstrated promising results in clinical trials. 3) Adoptive T-cell therapies, such as tumor-infiltrating lymphocytes (TILs), which are being investigated for their potential to enhance immune response against cervical cancer.

Summary

This trial is testing a combination of two drugs, pembrolizumab and olaparib, in patients with advanced or recurrent cervical cancer who have already had chemotherapy. Pembrolizumab helps the immune system fight the cancer, while olaparib stops cancer cells from repairing themselves. Olaparib has been approved for use in various cancers, including ovarian and breast cancer. The goal is to find a more effective treatment for these patients.

Who is the study for?

This trial is for women aged 18+ with advanced or recurrent cervical cancer who've had ≤2 chemo treatments. They must not be pregnant, breastfeeding, and if of childbearing potential, agree to contraception. Participants need a life expectancy ≥16 weeks and adequate organ function as per specific criteria.

What is being tested?

The study tests the combination of pembrolizumab (an immunotherapy drug) and olaparib (a targeted therapy drug) in patients with cervical cancer that has returned or spread after standard chemotherapy. It's an open-label phase II trial where all participants receive the drugs.

What are the potential side effects?

Possible side effects include immune-related reactions affecting organs, infusion-related symptoms, fatigue, nausea, blood count changes increasing infection risk. Specific side effects from each drug may vary based on individual patient response.

Other Research

Pembrolizumab, a PD-1 inhibitor, enhances the immune system's ability to fight cervical cancer by blocking the PD-1 pathway, which cancer cells use to evade immune detection. Olaparib, a PARP inhibitor, induces cancer cell death by preventing DNA repair, particularly effective in cells with existing DNA repair deficiencies. These targeted treatments are significant for cervical cancer patients as they offer more precise and potentially more effective options with fewer side effects compared to conventional chemotherapy.
