Ovarian cancer is hard to detect early because symptoms are vague, but treatment for advanced disease has improved meaningfully with PARP inhibitor pills, especially for women with BRCA mutations or other DNA-repair defects. About half of all ovarian cancers carry these features and may benefit.

What's actually going on in research

Studies are testing PARP inhibitor combinations, antibody-drug conjugates that target ovarian-cancer-specific proteins, immunotherapy approaches, and new strategies for platinum-resistant disease. Researchers are also evaluating less-extensive surgery in select patients, maintenance therapy after first response, and screening in women with strong family history.

PARP inhibitor pills

Daily PARP inhibitor pills extend remission for many women, especially those with BRCA mutations or homologous recombination deficiency. Trials are testing combinations to reach more patients.

Antibody-drug conjugates

Targeted antibodies that carry chemotherapy directly to ovarian cancer cells are showing benefit in platinum-resistant disease, where options have been limited.

Genetic testing

All women with ovarian cancer should have tumor and inherited genetic testing, since BRCA and related mutations open doors to specific treatments and affect family members' risk.

What to know before you search

Eligibility often depends on tumor type (high-grade serous most common), stage, prior chemotherapy response, and BRCA or homologous recombination deficiency status.

What types of trials are currently open

  • Treatment trialsTesting new drugs or combinations in women with ovarian cancer to see if they extend remission or work in resistant disease.
  • Maintenance trialsTesting whether continuing a treatment after chemotherapy keeps the cancer in remission longer.
  • Surgical trialsComparing different surgical approaches, including timing of surgery and extent of tissue removal.
  • Screening trialsTesting strategies to detect ovarian cancer earlier, especially in women with family history or BRCA mutations.
  • Supportive care trialsTesting ways to manage neuropathy, fatigue, and other side effects of long-term chemotherapy.
