About this study

Official title: A Randomized Phase III, Two-Arm Trial of Paclitaxel/Carboplatin/Maintenance Letrozole Versus Letrozole Monotherapy in Patients With Stage II-IV, Primary Low-Grade Serous Carcinoma of the Ovary or Peritoneum

This phase III trial studies how well letrozole with or without paclitaxel and carboplatin works in treating patients with stage II-IV low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum. Letrozole is an enzyme inhibitor that lowers the amount of estrogen made by the body which in turn may stop the growth of tumor cells that need estrogen to grow. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving letrozole alone or in combination with paclitaxel and carboplatin works better in treating patients with low-grade serous carcinoma of the ovary, fallopian tube, or peritoneum compared to paclitaxel and carboplatin without letrozole.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To examine if letrozole monotherapy/maintenance (L/L) is non-inferior to intravenous (IV) paclitaxel/carboplatin and maintenance letrozole (CT/L) with respect to progression-free survival (PFS) in women with stage II-IV primary low-grade serous carcinoma of the ovary or peritoneum after primary surgical cytoreduction.

SECONDARY OBJECTIVES:

  1. To compare the nature, frequency and maximum degree of toxicity as assessed by Common Terminology Criteria for Adverse Events (CTCAE) version (v) 5.0 for each treatment arm.

II. To compare the relative frequency of objective tumor response in those with measurable disease after cytoreductive surgery for each treatment arm.

III. To compare overall survival for each treatment arm. IV. To compare the CT/L and L/L arms with respect to patients' adherence to letrozole therapy as measured by pill counts.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive paclitaxel IV over 3 hours and carboplatin IV on day 1. Cycles repeat every 21 days for up to 6 cycles. Patients then receive letrozole orally (PO) once daily (QD) in the absence of disease progression or unacceptable toxicity. Patients undergo blood collection and tumor biopsy during screening as well as medical imaging throughout the study.

ARM II: Patients receive letrozole PO QD. Cycles repeat every 21 days for up to 6 cycles. Patients then receive letrozole orally PO QD in the absence of disease progression or unacceptable toxicity as maintenance therapy. Patients undergo blood collection and tumor biopsy during screening as well as medical imaging throughout the study.

After completion of study treatment/intervention, patients/participants are followed up every 3 months for 1 year, then every 6 months for 3 years, then annually thereafter.

What is being measured

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

  1. Progression-free survival (PFS)

    The PFS comparison will be assessed at the second interim and final analyses using a logrank test stratified by country and residual disease status. Estimates for the letrozole/letrozole (L/L) vs paclitaxel/carboplatin/letrozole (CT/L) hazard ratio and its confidence interval will be obtained using a stratified Cox proportional hazards model. Potential confounding factors, including the stratification factors, performance status and self-declared racial designation will be considered in a final exploratory model. A forest plot of treatment hazard ratios with confidence intervals within subgroups will also be reported. PFS will be characterized by treatment group with Kaplan-Meier plots and estimates of the median PFS.

    Measured: Time from the randomized treatment assignment to documentation of disease progression (Response Evaluation Criteria in Solid Tumors 1.1) or death from any cause, whichever comes first, assessed up to 8 years

Secondary outcomes (5)

  1. Incidence of adverse events (AE)

    The nature, frequency and degree of toxicity will be tabulated at the System Organ Class and AE Term levels using Common Terminology Criteria for Adverse Events version 5.0. Each patient will be represented according the maximum grade observed for each term, within randomized treatment assignment. Tabulations will show the number and percentage of patients by maximum grade, within their randomized treatment assignment.

    Measured: Up to 8 years

  2. Objective response rate (ORR)

    Will be estimated as the binomial proportion of patients with best overall response of complete response (CR) or partial response (PR) among patients with measurable disease after cytoreductive surgery. Response rates and their 95% Wilson-Score confidence intervals will be estimated for each treatment arm, using the randomized treatment assignment. The odds-ratio for ORR in the L/L vs CT/L arms will be estimated from the multivariable logistic regression model adjusted for stratification factors.

    Measured: Up to 8 years

  3. Duration of response

    Will be defined among patients with best overall response of CR or PR. Comparison of response duration between the randomized treatment arms will be supported by Kaplan Meier methods, and the corresponding estimates for median duration and its 95% confidence intervals.

    Measured: Time from documentation of response under documentation of progression or death, which is observed first, assessed up to 8 years

  4. Overall survival (OS)

    Differences in OS across the randomized treatment groups will be assessed using Kaplan Meier methods, with median time to death estimates and the corresponding 95% confidence intervals. The L/L vs CT/L hazard ratio will be estimated by a proportional hazards model stratified by the randomization stratification factors.

    Measured: Time between randomization and death from any cause, assessed up to 8 years

  5. Adherence to letrozole maintenance therapy

    Will be quantified as the mean rate of adherence (MRA), calculated as the proportion of product not returned divided by the number of days since the previous visit at which study products were dispensed. Currently, the letrozole is delivered in a 2.5 mg pill, and the recommended dose is 2.5 mg per day. This outcome will be computed for each treatment cycle (generally 21 days). The mean MRA will be compared between the randomized treatment groups using linear mixed model methods. The model will be specified with a random patient effect, and fixed effects for randomized treatment indicator, time (cycle number) and the interaction, with an adjustment for the protocol stratification factors. Primary interest is in the difference in mean (MRA) at cycles 1, 6 and 12 between the treatment group. The results will be reported as the estimated mean (MRA) and 95% confidence intervals for each treatment/time combination. Treatment differences within stratification factors may also be considered.

    Measured: At cycles 1, 6, and 12
