Abstract
BACKGROUND Human papillomavirus (HPV) types 16/18 drive oncogenesis for most patients with cervical, anal, and penile cancers. MEDI0457, a therapeutic DNA vaccine containing plasmids for E6 and E7 HPV-16/18 viral oncogenes and IL-12 adjuvant, is safe and provokes an immune response against E6/E7. We tested MEDI0457 with the anti-PD-L1 antibody durvalumab for patients with HPV-associated cancers. METHODS Patients with recurrent/metastatic, treatment-refractory HPV-16/18 cervical cancer, or rare HPV-associated (anal and penile) cancers were eligible. Prior immune checkpoint inhibition was not permitted. Patients received MEDI0457 7 mg intramuscularly (weeks 1, 3, 7, 12, and every 8 weeks thereafter) and durvalumab 1500 mg intravenously every 4 weeks. The primary endpoint was overall response (RECIST 1.1). In this Simon two-stage phase 2 trial (Ho: p < 0.15; Ha: p ≥ 0.35), ≥2 responses were needed in both cervical and non-cervical cohorts during the first stage for the trial to proceed to stage 2 with an additional 25 patients (34 total) enrolled. RESULTS Twenty-one patients (12 cervical, 7 anal, and 2 penile) were evaluable for toxicity and 19 for response Overall response rate was 21% (95% CI, 6%-46%) among evaluable patients. Disease control rate was 37% (95% CI, 16%-62%). Median duration of response among responders was 21.8 months (95% CI, 9.7%-not estimable). Median progression-free survival was 4.6 months (95% CI, 2.8%-7.2%). Median overall survival was 17.7 months (95% CI, 7.6%-not estimable). Grades 3-4 treatment-related adverse events occurred in 6 (23%) participants. CONCLUSIONS The combination of MEDI0457 and durvalumab demonstrated acceptable safety and tolerability in patients with advanced HPV-16/18 cancers. The low ORR among patients with cervical cancer led to study discontinuation despite a clinically meaningful disease control rate.

Abstract
Abstract
Background: Despite high rates of remission after frontline management, most patients with advanced stage ovarian cancer recur. Second look laparoscopy (SLL) can provide more sensitive detection of minimal residual disease (MRD) allowing for more individualized prognostication and possible therapeutic intervention. It may also assess tumor biology and microenvironment associated with undetectable chemoresistant MRD phase of ovarian cancer. The objective of this study was to determine SLL feasibility, and clinicopathologic and molecular characteristics of MRD after frontline therapy in ovarian cancer.
Methods: SLL was offered to patients with stage III-IV high grade epithelial ovarian cancer who achieved complete response after frontline surgery and 6 cycles of carboplatin and paclitaxel chemotherapy. Patients were offered standard of care or investigational management options based on homologous recombination deficiency (HRD) and MRD status at SLL. Preliminary translational studies included RNAseq for comparison of serial, matched tumor from primary or interval TRS and SLL derived MRD+ biopsies at the time of SLL. In addition, Nanostring analyses of SLL surgical biopsies both with and without residual tumor were performed. Molecular profiling employed hierarchical clustering, principle component analysis, non-parametric testing, and pathway analyses.
Results: Between 4/2017- 7/2021, 39 patients underwent SLL. The majority had stage III disease (74%), high grade serous histology (90%) and underwent neoadjuvant chemotherapy with interval tumor reductive surgery (TRS; 54%). MRD was present in 49% (n=19) of patients and was more frequent among neoadjuvant chemotherapy recipients (73% vs 26%, P=0.015) and patients with homologous recombination proficient tumors (81% vs 25%, P=0.01). Most patients without MRD were dispositioned to observation; 4 patients with HRD received a PARP inhibitor per standard of care. All other patients with MRD received bevacizumab as part of a clinical trial, except for one patient who received a PARP inhibitor. Median follow-up was 6.74 months (range 0.66 - 28.62). Presence of MRD was associated with worse PFS (HR 3.7, 95% CI 1.3- 10.9; 5.5 vs 24.6 months; P= 0.02). Based on transcriptional signature, MRD are immunologically distinct from untreated tumors or those collected at interval TRS (after 3 cycles of chemo) but also displayed heterogeneity with two distinct subclusters.
Conclusions: SLL to assess for MRD has potential to further individualize post-frontline therapy, and identify patients at high risk for progression for early intervention clinical trials. Transcriptional profiling suggests that MRD phase of ovarian cancer is characterized by a distinct, heterogeneous, and evolving tumor and immune microenvironment.
