About this study

Official title: Phase I-II Study to Evaluate the Safety, Tolerability, and Efficacy of Lurbinectedin and Dostarlimab in Patients with Advanced/Recurrent Endometrial Cancer with Disease Progression Following Previous Platinum Chemotherapy Therapy

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.

Read the detailed description

This study is a phase I-II clinical trial conducted to evaluate the safety, tolerability, and efficacy of lurbinectedin and dostarlimab combination therapy in patients with advanced or recurrent endometrial cancer. The trial follows a multicenter, open-label design and comprises two phases: a dose escalation phase (Phase I) and an expansion phase (Phase II). The primary endpoints include determining the maximum tolerated dose (MTD), recommended dose for further investigation, and objective response rate (ORR). Secondary endpoints encompass safety, pharmacokinetics, pharmacogenomics, progression-free survival (PFS), duration of response (DOR), clinical benefit rate (CBR), overall survival (OS), and quality of life assessments.

Study Treatments:

Lurbinectedin: Lurbinectedin is administered as a lyophilized powder for concentrate for infusion, reconstituted with sterile water for injection to achieve a concentration of 0.5 mg/mL. The initial dose for infusion is 2.6 mg/m^2, diluted in either 5% glucose solution or 0.9% sodium chloride solution. During Phase I, dose adjustments are based on body surface area calculated using the DuBois formula.

Dostarlimab: Dostarlimab is supplied in vials containing 500 mg at a concentration of 50 mg/mL. The recommended dose is a fixed dose of 500 mg administered intravenously over 30 minutes. Treatment cycles consist of administration on Day 1 of a 21-day cycle, with dostarlimab followed by lurbinectedin in combination therapy.

During the dose escalation phase (Phase I), a predefined dose escalation scheme is employed, starting with dose level (DL) -1 and progressing to DL1, DL2, and subsequent levels as per the protocol. Dose escalation is guided by the occurrence of dose-limiting toxicities (DLTs) and the determination of the MTD. Once the MTD is established, the expansion phase (Phase II) begins, wherein additional patients receive treatment at the recommended dose to further evaluate safety and efficacy outcomes.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum Tolerated Dose (MTD) and Recommended Dose (RD) Determination

    This measure involves identifying the highest dose of lurbinectedin in combination with dostarlimab that can be administered without causing unacceptable toxicity. The recommended dose for further evaluation in Phase II will also be determined.

    Measured: MTD and RD will be assessed during the Phase I portion of the study, the time frame will be arround 6 months.

  2. Evaluation of Lurbinectedin and Dostarlimab Combination Therapy in Advanced/Recurrent Cervical Cancer Patients

    This objective aims to assess the efficacy of lurbinectedin in combination with dostarlimab in advanced or recurrent cervical cancer patients who have experienced disease progression after platinum-based chemotherapy. The primary objective is to evaluate the confirmed tumor response rate, as defined by RECIST v1.1 criteria, in patients without alterations in the MMR system.

    Measured: This objective will be assessed during the Phase II portion of the study, the time frame will be arround 6 months.

Secondary outcomes (6)
  1. Safety Evaluation of Lurbinectedin in combination with Dostarlimab

    Safety will be assessed by monitoring adverse events (AEs) using the National Cancer Institute's Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0

    Measured: Safety evaluations will occur throughout the study, starting from the first dose administration and continuing until the end of the study, an average of 1 year

  2. Evaluate the progression-free survival (PFS)

    Evaluate the time from study entry until disease progression or death from any cause.

    Measured: These efficacy endpoints will be evaluated throughout the study, with regular assessments during follow-up visits, up to 1 year

  3. Pharmacokinetic (PK) and Pharmacogenomic Evaluation

    PK parameters will be assessed to determine the drug's concentration in plasma over time.

    Measured: PK and pharmacogenomic evaluations will occur at specified time points during the study (12 months).

  4. Overall Response Rate (ORR)

    The proportion of patients with a complete or partial response to treatment, assessed by RECIST v.1.1 criteria, specifically in the Phase II portion of the study.

    Measured: ORR will be assessed after completion of treatment cycles and response evaluations according to RECIST v.1.1 criteria(1 year).

  5. Evaluate the Duration of Response (DOR)

    The objective is to analyse the time from the first documented response until disease progression or death.

    Measured: Safety evaluations will occur throughout the study, starting from the first dose administration and continuing until the end of the study, an average of 1 year

  6. Evaluate the Clinical Benefit Rate (CBR)

    The objective is to examinate the time from study entry until death from any cause. Survival Rates: The percentage of patients who survive at specified time points (6, 12, 18, and 24 months)

    Measured: Safety evaluations will occur throughout the study, starting from the first dose administration and continuing until the end of the study, an average of 24 months
