6002 Background: SOLO2 (ENGOT ov-21; NCT01874353) showed that maintenance therapy with the PARP inhibitor olaparib in pts with platinum-sensitive relapsed ovarian cancer (PSROC) and a BRCA mutation (BRCAm) led to a statistically significant improvement in median progression-free survival (PFS) of 13.6 months vs placebo (hazard ratio [HR] 0.30). Time to second progression or death significantly improved (Pujade-Lauraine et al Lancet Oncol 2017) and a quality-adjusted PFS benefit was seen (Friedlander et al Lancet Oncol 2018) with maintenance olaparib vs placebo. We report the preplanned final OS analysis for SOLO2. Methods: Pts with PSROC and a BRCAm who had received ≥2 lines of treatment and were in response to their most recent platinum-based chemotherapy received maintenance olaparib (300 mg bid tablets) or placebo. Pts were stratified by response to previous chemotherapy (complete vs partial) and length of platinum-free interval (>6–12 months vs >12 months). OS was a secondary endpoint. The only preplanned OS sensitivity analysis was an OS analysis in the Myriad germline BRCAm subset (Myriad BRAC Analysis test). Results: At final data cut-off (Feb 3, 2020), median follow-up was 65 months in both treatment arms. A long-term treatment benefit was seen with olaparib vs placebo with an OS HR of 0.74 (95% confidence interval [CI] 0.54–1.00) in the full analysis set (FAS; unadjusted for crossover; 38.4% of placebo pts crossed over to a PARP inhibitor) (Table). At 5 years: by Kaplan-Meier estimates, 28.3% of pts in the olaparib arm vs 12.8% of pts in the placebo arm were alive and had still not received subsequent treatment; 42.1% of olaparib pts vs 33.2% of placebo pts were alive. The long-term tolerability profile of olaparib was generally consistent with that reported previously. Conclusions: In the final analysis of SOLO2, maintenance olaparib provided an unprecedented improvement of 12.9 months in median OS vs placebo. This is the first study with olaparib tablets, and the first since Study 19 (NCT00753545), to provide long-term follow-up and final OS data in pts with PSROC and a BRCAm. Clinical trial information: NCT01874353. [Table: see text]

5533 Background: In Study 19 (NCT00753545), a RCT in 265 pts with PSR SOC, the oral PARP inhibitor olaparib significantly improved progression-free survival (PFS) vs placebo (PBO), with the greatest benefit seen in pts with a BRCA1/2 mutation ( BRCAm); an interim overall survival (OS) analysis suggested an advantage for olaparib-treated pts (DCO: Sep 30, 2015; Ledermann et al, 2016). We report a planned final analysis of the long-term benefit of olaparib in pts with PSR SOC in Study 19. Methods: Pts who had received ≥2 prior regimens of platinum-based chemotherapy and were in response to their most recent regimen received olaparib (400 mg bid; capsules) or PBO until disease progression. Retrospective germline or tumor testing resulted in a known BRCAm status for 254/265 pts (96%). Results: At final DCO (May 9, 2016) median OS follow-up was 78.0 months. A long-term treatment benefit and the final hazard ratio (HR) for OS vs PBO (unadjusted for crossover: 13% of PBO pts – full analysis set [FAS]; 23% of PBO pts – BRCAm subgroup) is shown (Table). Details of BRCAwt pts on treatment for ≥6 years will be presented. No new safety signals or changes in olaparib tolerability profile were seen. Conclusions: The Study 19 final analysis shows that olaparib provides clinically significant, long-term treatment benefit in pts with PSR SOC. A durable benefit was seen in ≥10% of BRCAm and BRCAwt pts, who continued to receive and benefit from olaparib for ≥6 years–unprecedented in the relapsed ovarian cancer setting. Olaparib is well tolerated in this pt population and the analysis suggests olaparib confers an OS benefit in BRCAm pts. Clinical trial information: NCT00753545. [Table: see text]

Advanced Stages

Ovarian cancer is one of the most common cancers of the reproductive organs. As there are no symptoms in the early stages, it is mainly detected in the advanced stages. Even then, the symptoms are non-specific and include, for example, abdominal pain, early satiety, or changes in bowel habits. Both biochemical marker levels and imaging studies are used in the initial diagnosis. However, it should be emphasized that they are not characterized by high specificity. Treatment is multistage, and usually first-line debulking surgery is used followed by platinum-based chemotherapy. Here we present a clinical case of a 56-year-old female, a carrier of a mutation in the BRCA1 gene, with a history of breast cancer and with recurrent epithelial ovarian cancer. The patient was qualified for treatment with a PARP inhibitor and is currently undergoing treatment with olaparib. In the patient’s follow up of 50 months to date, there has been no recurrence of cancer. Few side effects have been observed, and the most serious one that can be effectively treated is anemia. On the basis of the described case, the authors concluded that olaparib treatment is effective, relatively safe, and does not significantly affect daily functioning.

5545 Background: In the Phase II Study 19 trial (NCT00753545; Ledermann et al Lancet Oncol 2014), maintenance olaparib improved progression-free survival (PFS) vs placebo in PSR OC pts, including non-BRCAm pts. A significant PFS benefit was also seen with maintenance olaparib vs placebo in gBRCAm PSR OC pts in the Phase III SOLO2 trial (NCT01874353; Pujade-Lauraine et al Lancet Oncol 2017). To investigate olaparib maintenance monotherapy in non-gBRCAm PSR OC pts who had received ≥2 prior lines of platinum-based chemotherapy (PBC), we performed the Phase IIIb, single-arm, OPINION study (NCT03402841). Methods: Pts had high-grade serous or endometrioid OC and were in complete response (CR) or partial response (PR) to PBC. Pts received maintenance olaparib (tablets; 300 mg bid) until disease progression or unacceptable toxicity. The primary endpoint was investigator-assessed PFS (modified RECIST v1.1). Secondary endpoints included PFS by homologous recombination deficiency (HRD) and somatic BRCA mutation (sBRCAm) status determined by central Myriad tumor and germline testing; and time to first subsequent treatment (TFST). The primary analysis was planned for 18 months (mo) after the last patient was enrolled. Results: 279 pts were enrolled from 17 countries (mean age: 64 years); 253 pts (90.7%) were confirmed non-gBRCAm. At data cut-off (Oct 2, 2020), median PFS was 9.2 mo (95% CI 7.6–10.9), with 210 PFS events (75.3% maturity). 65.3%, 38.5% and 24.3% of pts were progression-free (PF) at 6, 12 and 18 mo, respectively. The Table shows PFS in key subgroups. Median TFST was 13.9 mo (95% CI 11.5–16.4). Median exposure to olaparib was 9.4 mo (range 0.0–31.9). Grade ≥3 treatment-emergent adverse events (TEAEs) occurred in 29.0% of pts and serious TEAEs in 19.7% of pts. TEAEs led to dose interruption, dose reduction and treatment discontinuation in 47.0%, 22.6% and 7.5% of pts, respectively. Conclusions: Our findings support the use of olaparib maintenance therapy in non-gBRCAm PSR OC pts, consistent with our interim analysis and previous trials in this setting.

IntroductionTo evaluate clinical outcomes for patients with localized recurrent ovarian cancer treated with salvage radiotherapy.MethodsIn a retrospective single institutional analysis, we identified 40 patients who received salvage radiotherapy for localized ovarian cancer recurrence from January 1995 to June 2011. Recurrent disease was categorized as: pelvic peritoneal (45%, 18), extraperitoneal/nodal (35%, 14), or vaginal (20%, eight). Actuarial disease-free and overall survival estimates were calculated by Kaplan–Meier and prognostic factors evaluated by the Cox proportional hazards model.ResultsMedian follow-up was 42 months. Median patient age was 54 years (range, 27–78). Histologic subtypes were: serous (58%, 23), endometrioid (15%, six), clear cell (13%, five), mucinous (8%, three), and other (8%, three). At the time of salvage radiotherapy, surgical cytoreduction was performed in 60% (24) and 68% (27) had platinum-sensitive disease. Most patients (63%, 25) received salvage radiotherapy at the time of first recurrence. Relapse after salvage radiotherapy occurred in 29 patients at a median time of 16 months and was outside the radiotherapy field in 62%. 18 At 3 years, disease-free and overall survival rates were 18% and 80%, respectively. On multivariate analysis, non-serous histology (hazards ratio 0.3, 95% CI 0.1–0.7) and platinum-sensitivity (hazards ratio 0.2, 95% CI 0.1–0.5) were associated with lower relapse risk. Platinum-sensitivity was also associated with overall survival (hazards ratio 0.4, 95% CI 0.1–1.0). Four patients (10%) were long-term survivors without recurrence 5 years after salvage radiotherapy. Of the five patients with clear cell histology, none experienced relapse at the time of last follow-up.DiscussionPatients with non-serous and/or platinum-sensitive ovarian cancer had the greatest benefit from salvage radiotherapy for localized recurrent disease. Although relapse was common, radiotherapy prolonged recurrence for > 1 year in most patients and four were long-term survivors.

Tablet Formulations

Olaparib is a first-in-class PARP inhibitor that has demonstrated efficacy as maintenance therapy in patients with ovarian cancer. It has been approved as a capsule formulation and after the publication of data from SOLO2 study became available also as tablet formulation. Due to different pharmacokinetic properties, these different formulations cannot be considered bioequivalent nor interchangeable. The tablet formulation has improved bioavailability, reducing pill burden and offering a more convenient dosage regimen. Furthermore, olaparib tablet formulation had a manageable tolerability profile if compared to capsule one, with most of adverse events of mild or moderate severity. Under this light, olaparib tablet formulation is a useful maintenance strategy for recurrent, platinum-sensitive ovarian cancer, providing a more convenient dosing option than the capsule formulation.

Clinical Trial Information

5505 Background: Previously, we reported that maintenance treatment with the oral PARP inhibitor olaparib (400 mg bid) led to a significant PFS improvement vs placebo in patients (pts) with platinum-sensitive relapsed SOC (Ledermann et al NEJM2012). A preplanned subgroup analysis from this randomized, double-blind Phase II trial (NCT00753545) suggested that olaparib may lead to a greater PFS, and an OS, benefit in pts with a known germline BRCAm (gBRCAm). Since gBRCA wild-type (gBRCAwt) pts may develop somatic tumor (t)BRCAm, efficacy analyses were performed for all pts with BRCAm. Methods: gBRCAm status was determined retrospectively for all consenting pts (n = 166) using blood samples taken before randomization. tBRCAm status was determined from archival tumor samples of 196 pts. We analyzed PFS/OS by gBRCAm and total BRCAm status. Preliminary data are reported. Results: gBRCA status was known for 218/265 pts (gBRCAm, 96; gBRCAwt, 122). Including tBRCAm, 136 pts had a BRCAm (BRCAwt, 116). gBRCAm pts had the greatest PFS benefit with olaparib maintenance vs placebo (median: 11.2 vs 4.1 months [m]; HR, 0.17; 95% CI 0.09-0.32; P<0.001) and a significant QoL improvement, as measured with Trial Outcome Index (OR, 4.08; 95% CI 1.11-19.85; p = 0.03). The PFS benefit was consistent when tBRCAm pts were included (median: 11.2 vs 4.3 m; HR, 0.19; 95% CI 0.11-0.32; p <0.0001). In an interim analysis of OS (58% maturity), a comparison of olaparib vs placebo in the overall population led to a HR of 0.88 (95% CI 0.64-1.21) with medians of 29.8 vs 27.8 m, respectively. Although HRs from the gBRCAm and gBRCAwt subgroups were similar (0.85 and 0.84, respectively), 13/37 gBRCAm placebo pts received a subsequent PARP inhibitor, confounding the OS data in this subgroup. The analysis of all BRCAm pts was less confounded and resulted in an OS HR of 0.74 (95% CI 0.46-1.19; median: 34.9 vs 31.9 m). 19 pts have received olaparib for >3 years. Olaparib tolerability was similar in BRCAm pts and the overall population. Conclusions: Olaparib maintenance treatment led to the greatest clinical benefit in pts with a BRCAm. These compelling data warrant confirmation in phase III trials. Clinical trial information: NCT00753545.

Compromise Design

TPS5615 Background: BRCA1 and BRCA2 genes are critical in homologous recombination DNA repair and have been implicated in familial breast and ovarian cancer tumorigenesis. Tumor cells with these mutations demonstrate increased sensitivity to cisplatin and poly(ADP-ribose) polymerase (PARP) inhibitors. 6MP was identified in a screen for novel drugs and found to selectively kill BRCA-defective cells in a xenograft model as effectively as the PARP inhibitor, AGO14699, even after these cells had acquired resistance to a PARP inhibitor or cisplatin (Issaeva 2010). Exploiting the genetic basis of these tumours enables us to develop a more tailored approach to therapy for patients with BRCA mutated cancers. This multi-center phase II single arm trial was set up to investigate the activity and safety of 6MP with methotrexate in patients with breast or ovarian cancer who are known to have a BRCA mutation. Methods: Two-stage Simon compromise design (Jung 2001, Jung 2004) with α=0.20, power=90% to detect an increase in activity from 10 to 20%. 1st stage: if ≤ 3/30 evaluable patients respond at 8 weeks the trial will be stopped for futility; 2nd stage: if ≥9/65 evaluable patients respond at 8 weeks the treatment will be regarded as potentially effective and a phase III trial will be considered if the treatment appears safe and well-tolerated. 65 patients with BRCA defective cancer progressing after at least one prior chemotherapy or relapsed platinum resistant ovarian cancer, ECOG performance status 0-2 will be recruited and treated with daily 6MP (75mg/m2 ) and weekly methotrexate (20mg/m2) until progression. The starting dose was later reduced by 25% due to excess of expected toxicity. Patients with low TPMT activity or a low/low genotype are excluded due to the risk of increased toxicity. Prior treatment with a PARP inhibitor is permissible. Primary outcome: objective response at 8 weeks: complete, partial response or stable disease defined by RECIST 1.1. Secondary outcomes include safety, PFS, OS and quality of life. Of the 46 patients screened for TMPT activity between 15 Jun2009 and 05Dec 2012 from 12 UK sites, 31 patients were recruited. The pre-specified activity goal for the 1st stage was met and accrual into the 2nd stage continues. Clinical trial information: 2009-016846-16.

290 Background: Atezo (anti–PD-L1) has demonstrated safety and efficacy in a broad range of cancers and is approved in the United States for mUC previously treated with platinum-based chemotherapy. Here we report long-term results in mUC from Phase Ia study NCT01375842 (PCD4989g). Methods: Previously treated mUC patients received atezo 15 mg/kg or 1200 mg IV q3w. Enrollment in this Phase Ia expansion cohort initially required PD-L1–selected status and later opened to patients regardless of PD-L1 expression on tumor-infiltrating immune cells. The primary endpoint was safety/tolerability. Secondary endpoints included investigator-assessed RECIST v1.1 ORR (confirmed), DOR and OS. Results: 95 patients were safety evaluable (Table). Median age was 66 years, 76% were male and 80% had primary bladder tumors. 61% had ECOG PS 1. 52% received ≥ 3 prior systemic therapies for mUC (70% platinum). Median treatment duration was 3 months (range: 0-32 months); 24% were treated for ≥ 1 year. Treatment-related AEs occurred in 66% (all Grade) and 8% (Grade 3-4) of patients. No treatment-related deaths were reported. In 94 objective response–evaluable patients (follow-up ≥ 12 weeks), the ORR was 27% (95% CI: 18, 37%), and the CR rate was 10%; the SD rate was 19%. mDOR was 22.1 months (95% CI: 12.1, NE months) in all patients; 56% of responses (7/9 CRs and 7/16 PRs) were ongoing at the December 15, 2015 data cutoff. With a 24-month median follow-up duration (range: 1+ to 32 months), the 1-year OS rate was 47% (95% CI: 36, 58%), and the 2-year rate was 29% (19, 40%); mOS is in the Table. Updated clinical data with further follow-up and analyses by PD-L1 status will be presented. Conclusions: Long-term treatment with atezo was well tolerated, without new safety signals in heavily pre-treated mUC patients. The durability of responses, including CRs, along with extended OS, confirm atezo as a new standard for previously treated mUC patients. Clinical trial information: NCT01375842. [Table: see text]

First Line Treatment

TPS5598 Background: Ovarian cancer (OC) is the leading cause of death from gynecologic cancers in US women. Despite high response rates to first-line treatment, ~70% of patients (pts) relapse within 3 years and then remain largely incurable. First-line treatment needs to be improved to achieve long-term remission in pts and improve the cure rate. The Phase III SOLO1 trial showed a meaningful clinical benefit for olap maintenance therapy in newly diagnosed OC pts with a BRCA mutation (Moore et al N Engl J Med 2018). Preliminary data suggest that combining a PD-L1 inhibitor, anti-angiogenic and PARP inhibitor (triplet therapy) may achieve a synergistic antitumor effect. The DUO-O study (NCT03737643) evaluates the efficacy and safety of treatment combinations involving standard-of-care platinum-based chemotherapy (chemo), VEGF inhibitor bev, anti-PD-L1 antibody durva and PARP inhibitor olap, in women with newly diagnosed advanced OC. Methods: Eligible pts for this double-blind, randomized, Phase III study must have newly diagnosed, advanced, high-grade epithelial OC and either have completed primary surgery or plan to have interval debulking surgery. Depending on their tumor BRCA mutation (tBRCAm) status (determined by central test), pts will join one of two independent cohorts. Pts in the non-tBRCAm cohort (n~906) will be randomized (1:1:1) before cycle 2 to: a) chemo + bev + placebo (for 6 cycles) followed by bev (15 mg/kg [total 15 months]) + placebo maintenance treatment (IV and tablets); b) chemo + bev + durva (6 cycles) followed by bev + durva (1120 mg q3w [total 15 months]) + placebo (tablets) maintenance treatment; or c) chemo + bev + durva (6 cycles) followed by bev + durva + olap (300 mg bd tablets [24 months]) maintenance treatment. Pts in the open-label tBRCAm cohort (n~150) will receive 6 cycles of chemo + durva followed by durva + olap maintenance therapy, with optional use of bev. The primary endpoint of progression-free survival will be assessed by modified RECIST 1.1. Key secondary endpoints include overall survival, overall response rate and duration of response. Enrollment began in January 2019. Clinical trial information: NCT03737643.
