SOLO-1 Trial Summary

This trial looked at olaparib as a possible treatment for ovarian cancer in patients who had the BRCA gene mutation.

Who is the study for?
This trial is for women with newly diagnosed high-grade ovarian cancer (FIGO stage III-IV) that have specific harmful mutations in BRCA genes. They should have responded well to first-line platinum-based chemotherapy and undergone debulking surgery if needed. Women with stable or worsening disease post-chemotherapy, early-stage cancer, multiple surgeries before the study, or previous chemo for abdominal tumors are excluded.Check my eligibility
What is being tested?
The trial tests Olaparib tablets as a maintenance therapy for patients who've had a positive response to initial chemotherapy. It's aimed at preventing cancer from coming back by targeting BRCA mutations which are common in high-grade ovarian cancers.See study design
What are the potential side effects?
While not specified here, common side effects of Olaparib can include nausea, fatigue, anemia (low red blood cell counts), vomiting, diarrhea, decreased appetite and taste changes. More serious but less common side effects may involve lung problems and risk of developing other cancers.

2Treatment groups
Experimental Treatment
Placebo Group
Group I: Olaparib tablets p.o. 300mg twice dailyExperimental Treatment1 Intervention
Olaparib/placebo tablets p.o 300mg twice daily for up to 3 years or until objective radiological disease progression as per RECIST as assessed by the Investigator. Patients with evidence of stable disease (or those who have progressed), may continue on treatment beyond 2 years, if in the patient's best interest. Dose reduction to 250mg and subsequently 200mg is permitted following confirmation of toxicity
Group II: Placebo tablets p.o. twice dailyPlacebo Group1 Intervention
Olaparib/placebo tablets p.o 300mg twice daily for up to 3 years or until objective radiological disease progression as per RECIST as assessed by the Investigator. Patients with evidence of stable disease (or those who have progressed), may continue on treatment beyond 2 years, if in the patient's best interest. Dose reduction to 250mg and subsequently 200mg is permitted following confirmation of toxicity
