Surufatinib Combined With Carboplatin/Paclitaxel and Surufatinib Combined With Olaparib as First-line and Maintenance Therapy for Newly Diagnosed High-risk Ovarian Cancer

Phase 2

Recruiting

• Conditions: Ovarian Cancer
• Interventions: Drug: Paclitaxel

• Registration Number: NCT06437353
• Lead Sponsor: Anhui Provincial Cancer Hospital

Brief Summary

The goal of this type of clinical trial study is to evaluate the safety and efficacy of Surufatinib combined with Carboplatin/Paclitaxel and Surufatinib combined with Olaparib as first-line and maintenance therapy for newly diagnosed high-risk ovarian cancer

Detailed Description

Patients will have tests and exams to see if they are eligible for the clinical trial.

First-line chemotherapy regimen:

Paclitaxel/Carboplatin(repeat every 3 weeks, total of 6 cycles):

* Paclitaxel: 175 mg/m², intravenous infusion, on day 1.

* Carboplatin: AUC 5, intravenous infusion, on day 1.

* For patients aged ≥70 years or those with comorbidities, the paclitaxel dose can be adjusted to 135 mg/m².

Surufatinib(repeat every 3 weeks, total of 5 cycles):

* Surufatinib is not used during the first postoperative cycle.

* Starting from the second postoperative cycle, surufatinib is administered at a dose of 250 mg once daily, taken continuously.

Maintenance Therapy Regimen:

HRD-positive Patients:

* Surufatinib: 250 mg once daily, taken continuously.

* Olaparib: 300 mg twice daily, with doses taken 12 hours apart. Olaparib can be used for a maximum of 2 years.

HRD-negative or HRD Status Unknown Patients:

* Surufatinib: 250 mg once daily, taken continuously.

Treatment continues until the patient experiences disease progression or meets other criteria for discontinuation of the study treatment as specified in the protocol.
