About this trial

The purpose of this study is to evaluate the tolerance, safety, efficacy, and pharmacokinetics of pressurized intraperitoneal aerosol chemotherapy (PIPAC) with paclitaxel in patients with platinum-resistant recurrent ovarian cancer and peritoneal carcinomatosis.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Age: Women aged 19-85 years.

Diagnosis: Histologically confirmed ovarian, fallopian tube, or peritoneal cancer.

Refractory: Disease progression during platinum-based chemotherapy.

Resistant: Progression within 6 months (24 weeks) post-platinum therapy.

Disqualifiers

≥2 distant metastases (excluding retroperitoneal lymph nodes, pleural effusion, and localized skin metastases).

Contraindications to paclitaxel per approved domestic labeling.

Hypersensitivity history to paclitaxel or PIPAC devices.

NYHA Class ≥II heart failure

Trial design

Sequential

Treatments tested in this trial

  • Pressurized intraperitoneal aerosol chemotherapy (PIPAC) using paclitaxel

    Drug

    All patients enrolled in this study receive PIPAC using paclitaxel under 12 mmHg at 6 weeks intervals (up to 9 cycles) 1. Phase 1 Design 1. Dose Escalation: Standard 3+3 design across 5 paclitaxel cohorts (20 → 40 → 67 → 100 → 140 mg/m²) using modified Fibonacci increments (100%, 67%, 50%, 40%). 2. Maximum tolerated dose(MTD) Determination * If ≥2/6 patients in cohort χ experience dose limiting toxicities(DLTs; Grade ≥3 toxicity per CTCAE v5.0, excluding manageable pain) and ≤1/6 in cohort χ-1, MTD = χ-1. * If no DLTs at 140 mg/m², Phase 1 concludes. 3. Dose Reduction * DLTs in 20 mg/m² trigger de-escalation to 10 mg/m². * If ≤1/6 DLTs in 10 mg/m² → RP2D; ≥2/6 DLTs → trial termination. 2. Phase 2 Design : Evaluates efficacy/safety of PIPAC at the RP2D in 23 patients, adjusting for 5-17% laparoscopic access failure.

2

Maximum tolerated dose

We consider dose escalation if 3 consecutive DLTs do not occur, or less than 1 in 6 DLTs occur, per standard 3+3 design. If DLT occurs in 2 or more of 6, the lower dose is considered the MTD if 1 or fewer DLTs are identified. In addition, the highest dose (140 mg/m2) is considered the MTD when 3 to 0 DLTs or 6 to 1 DLTs are identified at the highest dose. On the other hand, if the initial dose (20 mg/m2) is reduced to 10 mg/m2 to account for DLT, it is considered the MTD if no more than 1 in 6 develop DLT at that reduced dose.
