Sacituzumab Govitecan med Bevacizumab sammenlignet med sædvanlig kemoterapi (Carboplatin, pegyleret liposomal Doxorubicin og Bevacizumab) til behandling af tilbagevendende platinfølsom æggestokkræft efter PARP-hæmmer vedligeholdelsesterapi

6. november 2026 opdateret af: National Cancer Institute (NCI)

A Randomized Phase II Trial of Sacituzumab Govitecan-HZIY (SG) and Bevacizumab Versus Standard of Care Carboplatin, Pegylated Liposomal Doxorubicin (PLD) and Bevacizumab in Patients With Platinum-Sensitive Ovarian Cancer That Has Progressed on Prior Maintenance PARP Inhibitor Therapy

This phase II trial compares the effect of sacituzumab govitecan and bevacizumab to standard care (carboplatin, pegylated liposomal doxorubicin, and bevacizumab) in patients with ovarian cancer that has come back after an initial response to platinum therapy (platinum-sensitive), that has progressed after poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitor maintenance therapy (recurrent), and that has a mutation in the BRCA1 or BRCA2 genes or is homologous recombination deficient. Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a drug called govitecan. Sacituzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as TROP2 receptors, and delivers govitecan to kill them. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Liposomal doxorubicin is a form of the anticancer drug doxorubicin that is contained inside very tiny, fat-like particles. Liposomal doxorubicin may have fewer side effects and work better than other forms of the drug. Giving sacituzumab govitecan and bevacizumab may kill more tumor cells than standard care (carboplatin, pegylated liposomal doxorubicin, and bevacizumab) in patients with recurrent platinum-sensitive ovarian cancers that have BRCA1/2 mutations or homologous recombination deficiency.

Detaljeret beskrivelse

PRIMARY OBJECTIVE:

I. To assess the clinical activity of sacituzumab govitecan (sacituzumab govitecan-hziy [SG]) and bevacizumab (or an anti-VEGF antibody biosimilar) compared to standard of care carboplatin, pegylated liposomal doxorubicin hydrochloride (pegylated liposomal doxorubicin [PLD]) and bevacizumab (or an anti-VEGF antibody biosimilar), as measured by progression-free survival, in patients with platinum-sensitive ovarian cancer that has progressed while receiving first-line PARP inhibitor maintenance therapy.

SECONDARY OBJECTIVES:

I. To assess additional measures of clinical activity of SG and bevacizumab compared to standard of care carboplatin, PLD and bevacizumab in patients with recurrent platinum-sensitive ovarian cancer, as measured by the overall response rate, duration of response, and overall survival.

II. To assess the safety of SG and bevacizumab in patients with recurrent platinum-sensitive ovarian cancer.

III. To assess the effect of SG and bevacizumab on overall survival in recurrent platinum-sensitive ovarian cancer.

EXPLORATORY OBJECTIVES:

I. To correlate clinical activity of SG and bevacizumab with TROP2 expression and tumor-specific cell-free deoxyribonucleic acid (cfDNA).

II. To assess time to first subsequent therapy or death (TFST). III. To assess time to second subsequent therapy or death (TSST).

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM I: Patients receive carboplatin intravenously (IV) on day 1, PLD IV on day 1 (or gemcitabine IV on days 1 and 8), and bevacizumab (or anti-VEGF antibody biosimilar) IV on days 1 and 15 of each cycle. Cycles repeat every 21 days for 6-10 cycles in the absence of disease progression or unacceptable toxicity. After 6-10 cycles, patients proceed to maintenance therapy.

ARM II: Patients receive SG IV over 1-3 hours on days 1 and 8 and bevacizumab (or anti-VEGF antibody biosimilar) IV on day 1 of each cycle. Cycles repeat every 21 days for 6-10 cycles in the absence of disease progression or unacceptable toxicity. After 6-10 cycles, patients proceed to maintenance therapy.

MAINTENANCE: Patients receive bevacizumab (or anti-VEGF antibody biosimilar) IV on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity.

Patients in Arm I also undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) at screening and all patients undergo computed tomography (CT) and/or magnetic resonance imaging (MRI) and collection of blood samples throughout the trial.

After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Hvad måler undersøgelsen?

Primære resultatmål

Resultatmål
Foranstaltningsbeskrivelse
Tidsramme
Progression-free survival
Tidsramme: From randomization to either progressive disease or death from any cause, assessed up to 5 years

The primary analysis will compare progression-free survival between Arm II and Arm I using a stratified log-rank test. The corresponding hazard ratio will be estimated from a stratified Cox regression model. The treatment hazard ratio estimate and its 95% confidence interval will be estimated using proportional hazards models specified to be consistent with the logrank tests.

From randomization to either progressive disease or death from any cause, assessed up to 5 years

Tidsramme
Objective response rate (ORR)
Tidsramme: Within 12 months of starting maintenance therapy

The ORR is the percentage of evaluable patients who achieve a complete response (CR) or partial response (PR) within 12 months of starting maintenance therapy. The analysis will be based on physician-assessed responses according to Response Evaluation Criteria in Solid Tumors 1.1 criteria. Comparisons of ORR between the experimental and reference groups will use a multivariable logistic regression model, stratified by the randomization factors, to estimate the odds ratio. A 95% Jeffries confidence interval will also be calculated for the ORR in each treatment arm.

Within 12 months of starting maintenance therapy
Duration of response (DOR)
Tidsramme: From the first documented response (CR or PR) until disease progression or death, assessed up to 5 years

DOR will be visualized using Kaplan-Meier curves, and the treatment groups will be compared with a stratified log-rank test. A stratified Cox proportional hazards model will be used to estimate the hazard ratio for progression or death between the groups.

From the first documented response (CR or PR) until disease progression or death, assessed up to 5 years
Incidence of adverse events
Tidsramme: Up to 5 years

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

Up to 5 years
Overall survival
Tidsramme: From randomization to death from any cause, assessed up to 5 years

Estimates of treatment effect will be interpreted descriptively with associated confidence intervals, without formal hypothesis testing.

From randomization to death from any cause, assessed up to 5 years

Tidsramme
TROP2 expression
Tidsramme: Up to 5 years

TROP2 expression will be correlated with clinical activity of sacituzumab govitecan (SG) and bevacizumab to assess how the clinical effect of the randomized treatment is modified by TROP2 expression. Will formally test the interaction between the biomarker and the treatment assignment to assess whether this is a predictive biomarker. A logistic regression model will be used to test the treatment-by-TROP2 interaction on the odds of achieving a response. The odds ratio for the treatment effect will be estimated within each TROP2 subgroup. A Cox proportional hazards model will be fitted with main effects for treatment, TROP2 status, and a treatment-by-TROP2 interaction term. A statistically significant interaction term would suggest TROP2 is a predictive biomarker. The treatment effect will be estimated and displayed on a forest plot for TROP2-high and TROP2-low subgroups. Kaplan-Meier curves for PFS will be plotted for each treatment arm within each TROP2 subgroup.

Up to 5 years
Cell-free deoxyribonucleic acid (cfDNA)
Tidsramme: Up to 5 years

cfDNA expression will be correlated with clinical activity of SG and bevacizumab to assess how the clinical effect of the randomized treatment is modified by cfDNA expression. Will formally test the interaction between the biomarker and the treatment assignment to assess whether this is a predictive biomarker.

Up to 5 years
Time to first subsequent therapy or death (TFST)
Tidsramme: From randomization to the earliest occurrence of either first subsequent therapy or death, assessed up to 5 years

TFST distributions by randomized treatment assignment in the intent to treat population will be visualized using Kaplan-Meier curves. The effect of treatment assignment on TFST will be estimated using a Cox proportional hazards model, stratified by the randomization factors. Hazard ratio estimates and 95% confidence intervals will be reported to quantify the treatment effect. Treatment effects within strata will be presented in a forest plot.

From randomization to the earliest occurrence of either first subsequent therapy or death, assessed up to 5 years
Time to second subsequent therapy or death (TSST)
Tidsramme: From randomization to the earliest occurrence of either second subsequent therapy or death, assessed up to 5 years

TSST distributions by randomized treatment assignment in the intent to treat population will be visualized using Kaplan-Meier curves. The effect of treatment assignment on TSST will be estimated using a Cox proportional hazards model, stratified by the randomization factors. Hazard ratio estimates and 95% confidence intervals will be reported to quantify the treatment effect. Treatment effects within strata will be presented in a forest plot.
