Maintenance of pegylated liposomal doxorubicin/carboplatin in patients with advanced ovarian cancer: randomized study of an Asian Gynecologic Oncology Group.

ABSTRACT:

Objectives

An Asian Gynecologic Oncology Group phase III randomized trial was conducted to determine whether maintenance chemotherapy could improve progression-free survival (PFS) in stages III/IV ovarian cancer.

Methods

Between 2007 and 2014, 45 newly-diagnosed ovarian cancer patients were enrolled after complete remission and randomized (1:1) to arm A (4-weekly carboplatin area under the curve 4 and pegylated liposomal doxorubicin [PLD] 30 mg/m², n=24) for 6 cycles or arm B (observation, n=21). The primary end-point was PFS. A post hoc translational study was conducted to deep sequence BRCA/homologous recombination deficiency (HRD) genes, because BRCA/HRD mutations (BRCA/HRDm) are known to be associated with better prognosis.

Results

Enrollment was slow, accrual was closed when 7+ years had passed. With a median follow-up of 88.9 months, the median PFS was significantly better in arm A (55.5 months) than arm B (9.2 months) (hazard ratio [HR]=0.40; 95% confidence interval [CI]=0.19-0.87; p=0.020), yet the median overall survival was not significantly different in arm A (not reached) than arm B (95.1 months) (p=0.148). Overall grade 3/4 adverse events were more frequent in arm A than arm B (60.9% vs 0.0%) (p<0.001). Quality of life was generally not significantly different. Distribution of BRCA1/2m or BRCA/HRDm was not significantly biased between the two arms. Wild-type BRCA/non-HRD subgroup seemed to fare better with maintenance therapy (HR=0.35; 95% CI=0.11-1.18; p=0.091).

Conclusions

Despite limitations in small sample size, it suggests that maintenance carboplatin-PLD chemotherapy could improve PFS in advanced ovarian cancer.

Project description:BackgroundA phase 2, randomized, placebo-controlled trial was conducted in women with recurrent epithelial ovarian carcinoma to evaluate the efficacy and safety of motolimod-a Toll-like receptor 8 (TLR8) agonist that stimulates robust innate immune responses-combined with pegylated liposomal doxorubicin (PLD), a chemotherapeutic that induces immunogenic cell death.Patients and methodsWomen with ovarian, fallopian tube, or primary peritoneal carcinoma were randomized 1 : 1 to receive PLD in combination with blinded motolimod or placebo. Randomization was stratified by platinum-free interval (≤6 versus >6-12 months) and Gynecologic Oncology Group (GOG) performance status (0 versus 1). Treatment cycles were repeated every 28 days until disease progression.ResultsThe addition of motolimod to PLD did not significantly improve overall survival (OS; log rank one-sided P = 0.923, HR = 1.22) or progression-free survival (PFS; log rank one-sided P = 0.943, HR = 1.21). The combination was well tolerated, with no synergistic or unexpected serious toxicity. Most patients experienced adverse events of fatigue, anemia, nausea, decreased white blood cells, and constipation. In pre-specified subgroup analyses, motolimod-treated patients who experienced injection site reactions (ISR) had a lower risk of death compared with those who did not experience ISR. Additionally, pre-treatment in vitro responses of immune biomarkers to TLR8 stimulation predicted OS outcomes in patients receiving motolimod on study. Immune score (tumor infiltrating lymphocytes; TIL), TLR8 single-nucleotide polymorphisms, mutational status in BRCA and other DNA repair genes, and autoantibody biomarkers did not correlate with OS or PFS.ConclusionsThe addition of motolimod to PLD did not improve clinical outcomes compared with placebo. However, subset analyses identified statistically significant differences in the OS of motolimod-treated patients on the basis of ISR and in vitro immune responses. Collectively, these data may provide important clues for identifying patients for treatment with immunomodulatory agents in novel combinations and/or delivery approaches.Trial registrationClinicaltrials.gov, NCT 01666444.

Project description:ImportanceThere are substantial unmet therapeutic needs in patients with platinum-resistant recurrent ovarian cancer (PROC), and novel therapeutic strategies should be explored.ObjectiveTo evaluate the efficacy and safety of treatment with apatinib (a vascular endothelial growth factor receptor 2 tyrosine kinase inhibitor) plus pegylated liposomal doxorubicin (PLD) for PROC.Design, setting, and participantsThe APPROVE trial was performed as an open-label, randomized clinical trial at 11 hospitals in China between March 22, 2018, and November 16, 2020. Patients with histologically confirmed ovarian cancer who had experienced disease progression during or within 6 months of discontinuing any prior line of treatment with platinum-based chemotherapy were eligible. This primary analysis was based on data that were current as of January 28, 2021.InterventionsPatients received PLD alone (40 mg/m2, intravenously, every 4 weeks, for up to 6 cycles) or PLD plus apatinib (250 mg, orally, daily).Main outcomes and measuresThe primary end point was progression-free survival (PFS) by Response Evaluation Criteria in Solid Tumours (RECIST), version 1.1, in the intent-to-treat population.ResultsIn total, 152 female patients were randomized, with 78 (51.3%) in the apatinib plus PLD group (median age, 54 years; range, 22-76 years) and 74 (48.7%) in the PLD group (median age, 56 years; range, 33-72 years). The median follow-up duration was 8.7 months (IQR, 4.7-14.1 months). The median PFS was 5.8 months (95% CI, 3.8-8.8) for treatment with apatinib plus PLD vs 3.3 months (95% CI, 2.1-3.8) for PLD (hazard ratio, 0.44; 95% CI, 0.28-0.71; P < .001). The median overall survival was 23.0 months (95% CI, 18.9 to not reached) with treatment with apatinib plus PLD vs 14.4 months (95% CI, 12.1-23.4) with PLD (hazard ratio, 0.66; 95% CI, 0.40-1.09). The most frequent grade 3 or higher treatment-emergent adverse events were decreased neutrophil counts (11 [14.9%] in the apatinib plus PLD group vs 6 [8.3%] in the PLD group), hypertension (6 [8.1%] vs none), and decreased white blood cell count (5 [6.8%] vs 3 [4.2%]). Two patients receiving treatment with apatinib plus PLD experienced grade 2 fistulas.Conclusions and relevanceThis randomized clinical trial found that treatment with apatinib plus PLD showed promising efficacy and manageable toxic effects in patients with PROC and may be a new alternative treatment option in this setting.Trial registrationClinicaltrials.gov Identifier: NCT04348032.
