Purpose Pertuzumab is a humanized monoclonal antibody that inhibits human epidermal growth factor receptor 2 (HER2) heterodimerization and has single-agent activity in recurrent epithelial ovarian cancer. The primary objective of this phase II study was to characterize the safety and estimate progression-free survival (PFS) of pertuzumab with gemcitabine in patients with platinum-resistant ovarian cancer. Patients and Methods Patients with advanced, platinum-resistant epithelial ovarian, fallopian tube, or primary peritoneal cancer who had received a maximum of one prior treatment for recurrent cancer were randomly assigned to gemcitabine plus either pertuzumab or placebo. Collection of archival tissue was mandatory to permit exploration of biomarkers that would predict benefit from pertuzumab in this setting. Results One hundred thirty patients (65 per arm) were treated. Baseline characteristics were similar between arms. The adjusted hazard ratio (HR) for PFS was 0.66 (95% CI, 0.43 to 1.03; P = .07) in favor of gemcitabine + pertuzumab. The objective response rate was 13.8% in patients who received gemcitabine + pertuzumab compared with 4.6% in patients who received gemcitabine + placebo. In patients whose tumors had low HER3 mRNA expression (< median, n = 61), an increased treatment benefit was observed in the gemcitabine + pertuzumab arm compared with the gemcitabine alone arm (PFS HR = 0.32; 95% CI, 0.17 to 0.59; P = .0002). Grade 3 to 4 neutropenia, diarrhea, and back pain were increased in patients treated with gemcitabine + pertuzumab. Symptomatic congestive heart failure was reported in one patient in the gemcitabine + pertuzumab arm. Conclusion Pertuzumab may add activity to gemcitabine for the treatment of platinum-resistant ovarian cancer. Low HER3 mRNA expression may predict pertuzumab clinical benefit and be a valuable prognostic marker.

Results from a phase II randomized, placebo-controlled, double-blind trial suggest improved PFS with the addition of pertuzumab to gemcitabine in patients with platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer

5507 Background: Pertuzumab (P) is a humanized monoclonal antibody that blocks the ability of HER2 to heterodimerize with other HER/ErbB receptors. As a single agent, P has demonstrated clinical activity in relapsed/refractory epithelial ovarian cancer (EOC). Since platinum-resistant (CDDP-R) EOC remains a difficult disease to treat, this phase II study was conducted to determine if addition of P to gemcitabine (G) would improve results. Methods: Patients with CDDP-R EOC (including ovarian, fallopian tube, or primary peritoneal cancer) who had received up to one prior treatment for CDDP-R disease were randomized to Gem 800 mg/m2 on D1, 8 of a 21-day cycle ± P or placebo (pl). P was given as an 840 mg initial dose followed by 420mg IV every 3 weeks. Tumor response was assessed by RECIST every 6 weeks using GOG criteria. The primary endpoint was progression free survival (PFS). Results: One hundred thirty patients (n = 65 each treatment cohort) were treated. Clinical characteristics were balanced between the treatment groups. Pts received a median of 2 prior regimens (range 1–6) for EOC. Based on 83 events, the adjusted hazard ratio for PFS was 0.67 (95% CI: 0.43–1.02), p =0.06 in favor of P+Gem. The median PFS was 3.0 months (0–8.7 months) vs. 2.6 months (0–9+ months), and the PFS rate at 4 months was 49% vs. 34% in the P+Gem and Gem/pl arms, respectively. The most common AEs increased in the P-treated pts were fatigue, nausea, diarrhea, back pain, Gr 3–4 neutropenia, rash, headache, stomatitis, epistaxis, and rhinorrhea. Clinically significant CHF was reported in one patient in the pertuzumab cohort. There was no imbalance in the LVEF results between treatment arms. One patient who received pertuzumab + gemcitabine experienced an adverse event that resulted in death (hemolytic-uremic syndrome). Conclusions: These data suggest that pertuzumab may add activity to gemcitabine as reflected by improvements in PFS in patients with CDDP-R ovarian, primary peritoneal, or fallopian tube cancer. Survival data will be presented at ASCO. No significant financial relationships to disclose.

TPS5607 Background: Elevated FRα expression is characteristic of a number of solid tumors, including EOC, thereby providing an attractive candidate for targeted therapeutic approaches. Mirvetuximab soravtansine is an antibody-drug conjugate (ADC), comprising a FRα-binding antibody linked to the tubulin-disrupting maytansinoid DM4, that has shown single agent clinical activity and a favorable safety profile in an ongoing, first-in-human phase 1 trial (NCT01609556). Methods: FORWARD I is a randomized phase 3 study designed to evaluate the efficacy of mirvetuximab soravtansine compared with that of standard-of-care chemotherapy in adult patients with platinum-resistant EOC, primary peritoneal cancer, or fallopian tube cancer. Confirmation of FRα positivity by immunohistochemistry (medium or high expression; ≥ 50% of cells with at least moderate staining intensity) and ≤ 3 prior lines of therapy are required for inclusion. A maximum of 333 patients are expected to be recruited. Patients will be randomized 2:1 to Arm 1 (intravenous mirvetuximab soravtansine at a dose of 6.0 mg/kg, calculated using adjusted ideal body weight, on Day 1 of a 21-day cycle) or Arm 2 (investigators’ choice chemotherapy: paclitaxel, pegylated liposomal doxorubicin, or topotecan). The primary efficacy endpoint is progression-free survival (PFS; by blinded independent central review) and secondary endpoints include objective response rate, quality of life, overall survival, safety and tolerability, and duration of response. The first patient was enrolled in January 2017. Clinical trial information: NCT02631876.

BackgroundAnti-programmed death 1 (PD1)/programmed cell death ligand 1 (PD-L1) therapies have shown modest activity as monotherapy in recurrent ovarian cancer. Platinum chemotherapies induce T-cell proliferation and enhance tumor recognition. We assessed activity and safety of pembrolizumab with carboplatin in recurrent platinum-resistant ovarian cancer.Patients and methodsThis phase I/II, single-arm clinical trial studied concurrent carboplatin and pembrolizumab in recurrent platinum-resistant ovarian, fallopian tube, and primary peritoneal cancer. Primary platinum refractory patients were excluded. Patients were treated after progression on subsequent non-platinum systemic therapy after becoming platinum resistant or refractory. Pembrolizumab 200 mg was given on day 1 and carboplatin area under the curve 2 on days 8 and 15 of a 3-week cycle until progression. Imaging was assessed by blinded independent review. PD-L1 expression was assessed by immunohistochemistry. Flow cytometry on peripheral blood mononuclear cells was performed for CD3, CD4, CD8, PD1, CTLA4 and Ki67.ResultsThe most common treatment-related adverse events were lymphopenia (18%) and anemia (9%) with most being grade 1 or 2 (93%). Of 29 patients treated, 23 patients were evaluable for best objective response: 10.3% (95% CI 2.2 to 27.4) had partial response (PR), 51.7% (95% CI 32.5 to 70.6) had stable disease (SD). 56.5% of patients had decreases in target lesions from baseline. All PD-L1-positive patients achieved PR (3/7, 42.8%) or SD (4/7, 57.2%). Median progression-free survival was 4.63 months (95% CI 4.3 to 4.96). Median OS was 11.3 months (95% CI 6.094 to 16.506). Peripheral CD8+PD1+Ki67+ T cells expanded after 3 (p=0.0015) and 5 (p=0.0023) cycles. CTLA4+PD1+CD8+ T cells decreased through the course of treatment up to the 12th cycle (p=0.004). When stratified by ratio of peripheral CD8+PD1+Ki67+ T cells to tumor burden at baseline, patients with a ratio ≥0.0375 who had a significantly longer median OS of 18.37 months compared with those with a ratio <0.0375 who had a median OS of 8.72 months (p=0.0099). No survival advantage was seen with stratification by tumor burden alone (p=0.24) or by CD8+PD1+Ki67+ T cells alone (p=0.53).ConclusionsPembrolizumab with carboplatin was well-tolerated and active in recurrent platinum-resistant ovarian cancer. A ratio of peripheral T-cell exhaustion to radiographic tumor burden may identify patients more likely to benefit from this chemoimmunotherapy.Trial registration numberNCT03029598.
