Summary

Background:

Endometrial cancer is a prevalent gynecological malignancy, with a significant number of cases diagnosed at an advanced stage or recurring following initial treatment. Platinum-based chemotherapy represents a standard treatment option for these patients; however, disease progression often occurs, highlighting the need for novel therapeutic approaches. Lurbinectedin, a synthetic analog of marine alkaloid-derived compounds, and dostarlimab, a monoclonal antibody targeting PD-1, have demonstrated promising antitumor activity in various malignancies. This phase I-II clinical trial seeks to evaluate the safety, tolerability, and efficacy of combining lurbinectedin and dostarlimab in patients with advanced or recurrent endometrial cancer who have experienced disease progression following platinum-based chemotherapy.

Primary Objectives:

To determine the maximum tolerated dose (MTD) and recommended dose for further investigation of lurbinectedin and dostarlimab in combination therapy for advanced or recurrent endometrial cancer.

To assess the antitumor activity of lurbinectedin and dostarlimab combination therapy, measured by objective response rate (ORR), in patients with advanced or recurrent endometrial cancer.

Secondary Objectives:

To evaluate the safety and tolerability of lurbinectedin and dostarlimab combination therapy in patients with advanced or recurrent endometrial cancer.

To characterize the pharmacokinetic profile of lurbinectedin and dostarlimab when administered in combination therapy.

To explore pharmacogenomic biomarkers predictive of response and/or resistance to lurbinectedin and dostarlimab combination therapy in patients with advanced or recurrent endometrial cancer.

To assess progression-free survival (PFS), duration of response (DOR), clinical benefit rate (CBR), and overall survival (OS) in patients receiving lurbinectedin and dostarlimab combination therapy for advanced or recurrent endometrial cancer.

To investigate the impact of lurbinectedin and dostarlimab combination therapy on quality of life and symptom control in patients with advanced or recurrent endometrial cancer.

Conditions

Interventions

DRUG

Lurbinectedin

participants will receive intravenous infusions of lurbinectedin at a dose of 2.6 mg/m², diluted in a minimum of 100 mL of either 5% glucose solution or 0.9% sodium chloride solution. The infusion will last for one hour and will be administered every three weeks.

DRUG
