Niraparib Rechallenge After Surgery in Ovarian Cancer Patients With Oligometastatic Progression (ANALLISA)

Phase II Study to Assess the Efficacy of Niraparib Rechallenge After Surgery in Ovarian Cancer Patients With Oligometastatic Progression (The ANALLISA Study)

The ANALLISA study is a fast, proof-of-concept, phase II clinical trial which aims to assess the efficacy of niraparib rechallenge treatment after secondary cytoreductive surgery in ovarian cancer (OC) patients with oligometastatic progression (OMP) after first maintenance therapy with any PARP inhibitor. A total of 30 patients with OC and OMP will be enrolled and will receive treatment with niraparib 300 or 200 mg, according to body weight or platelet count. Patients will start treatment within 8 weeks after surgery and will receive it until progressive disease or treatment discontinuation. The main purpose of the study is to evaluate progression-free survival (PFS) of niraparib rechallenge in OC patients with OMP and no residual disease after secondary cytoreductive surgery.

Study Overview

• Status: Recruiting
• Conditions: Ovarian Cancer; Oligometastatic Disease; Serous Ovarian Tumor
• Intervention / Treatment: Drug: Niraparib oral tablets

Detailed Description

This is a single-arm phase II clinical trial which will enroll female patients aged ≥ 18 years with high grade serous or endometrioid ovarian cancer (OC) who have had an oligometastatic progression (OMP) during or after the first maintenance therapy with any poly adenosine diphosphate (ADP) ribose polymerase inhibitor (PARPi). OMP is defined as 1-5 metastatic lesions. Patients with systemic metastatic disease are not eligible.

A total of 30 patients with OC and OMP will be enrolled and will receive treatment with niraparib 300 or 200 mg, according to body weight or platelet count. Patients will start treatment within 8 weeks after surgery and will receive it until progressive disease or treatment discontinuation.

The main objective of the study is to evaluate progression-free survival (PFS) of niraparib rechallenge in OC patients with OMP and no residual disease after secondary cytoreductive surgery. Main secondary objectives are to assess the PFS according to biomarker status (BRCAm, BRCAwt, HRD and HRP), the PFS by CA 125, the time to start of first subsequent therapy or death (TFST) and the overall survival (OS).
