What side effects are associated with this type of intervention?

Common treatments for ovarian cancer, such as chemotherapy with paclitaxel and carboplatin, can cause side effects including neurotoxicity, granulocytopenia, anemia, fatigue, nausea, and hair loss. Targeted therapies like PARP inhibitors (e.g., olaparib) may lead to nausea, fatigue, anemia, and increased infection risk. Tazemetostat, which inhibits tumor cell growth, can cause fatigue, nausea, and has potential teratogenic effects, necessitating effective contraception during treatment.

What prior FDA approvals exist?

Several drugs have been approved by the FDA for the treatment of ovarian cancer that work by inhibiting tumor cell growth, similar to tazemetostat. These include chemotherapeutic agents like paclitaxel and carboplatin, which kill cancer cells and prevent their division. Additionally, targeted therapies such as bevacizumab, a monoclonal antibody that inhibits angiogenesis, and PARP inhibitors like olaparib, niraparib, and rucaparib, which prevent cancer cells from repairing their DNA, have also been approved. These treatments aim to control tumor growth and spread, offering various mechanisms to combat ovarian cancer.

What other types of research exist?

Promising novel alternatives to Tazemetostat for ovarian cancer treatment in 2024 include: 1) PARP inhibitors such as Olaparib, Niraparib, and Rucaparib, which are effective in patients with BRCA mutations or homologous recombination deficiency. 2) Anti-angiogenic agents like Bevacizumab, which inhibit tumor blood vessel growth. 3) Immune checkpoint inhibitors such as Pembrolizumab, which enhance the immune system's ability to target cancer cells. 4) Combination therapies involving these agents, which may offer synergistic effects and improved outcomes.

Summary

This trial studies how well tazemetostat works in treating patients with ovarian or endometrial cancer that has come back. Tazemetostat aims to stop cancer cells from growing and spreading. The trial targets patients whose cancers have returned after initial treatment.

Who is the study for?

This trial is for adults with recurrent ovarian or endometrial cancer, specifically endometrioid or clear cell types. Participants must have completed prior treatments and be able to take oral medication. They should not be pregnant, have severe co-morbidities, bowel obstruction, HIV on antiretrovirals, a history of myeloid malignancies or recent therapeutic paracentesis.

What is being tested?

The trial tests Tazemetostat's effectiveness in treating recurrent ovarian or endometrial cancer. It's a phase II study where the drug aims to stop tumor growth by killing cells or preventing their division and spread. Imaging techniques like MRI and CT scans are used for evaluation.

What are the potential side effects?

While specific side effects of Tazemetostat aren't listed here, chemotherapy drugs can generally cause fatigue, nausea, hair loss, increased risk of infection due to low blood counts and may affect liver function.

Other Research

Common treatments for ovarian cancer, such as chemotherapy, work by targeting rapidly dividing cells. Agents like paclitaxel and carboplatin disrupt cell division and induce cell death, effectively reducing tumor size and spread. Targeted therapies, including PARP inhibitors, exploit specific genetic weaknesses in cancer cells to prevent DNA repair, leading to cell death. These mechanisms are crucial for ovarian cancer patients as they directly attack the cancer cells' ability to grow and spread, offering a chance to control the disease and improve survival rates.
