Olaparib treatment significantly improved objective response rate (primary end point) and progression-free survival versus nonplatinum chemotherapy in patients with BRCA-mutated platinum-sensitive relapsed ovarian cancer in the open-label phase III SOLO3 trial (ClinicalTrials.gov identifier: NCT02282020). We report final overall survival (OS; prespecified secondary end point), post hoc OS analysis by number of previous chemotherapy lines, and exploratory BRCA reversion mutation analysis. Two hundred sixty-six patients were randomly assigned 2:1 to olaparib tablets (300 mg twice daily; n = 178) or physician's choice of single-agent nonplatinum chemotherapy (pegylated liposomal doxorubicin, paclitaxel, gemcitabine, or topotecan; n = 88). OS was similar with olaparib versus chemotherapy (hazard ratio [HR], 1.07 [95% CI, 0.76 to 1.49]; P = .71, median 34.9 and 32.9 months, respectively, full analysis set). OS with olaparib was favorable in patients with two previous chemotherapy lines (HR, 0.83 [olaparib v chemotherapy] [95% CI, 0.51 to 1.38]; median 37.9 v 28.8 months); however, a potential detrimental effect was seen in patients with at least three previous chemotherapy lines (HR, 1.33 [95% CI, 0.84 to 2.18]; median 29.9 v 39.4 months). BRCA reversion mutations might have contributed to this finding. No patient randomly assigned to olaparib with a BRCA reversion mutation detected at baseline (6 of 170 [3.5%]) achieved an objective tumor response.

BACKGROUND: In the ARIEL4 trial of rucaparib versus standard-of-care chemotherapy in patients with relapsed BRCA-mutated ovarian carcinoma, the primary endpoint was met, showing improved investigator-assessed progression-free survival with rucaparib. Here, we present the final overall survival analysis of the trial and other post-progression outcomes. METHODS: This open-label, randomised, controlled phase 3 trial was done at 64 hospitals and cancer centres in 12 countries, including Brazil, Canada, Czech Republic, Hungary, Israel, Italy, Poland, Russia, Spain, Ukraine, the UK, and the USA. Eligible patients were women aged 18 or older with BRCA1 or BRCA2-mutated ovarian carcinoma and had received at least two previous chemotherapy regimens. Patients had to have evaluable disease as per Response Evaluation Criteria in Solid Tumors (RECIST; version 1.1) criteria and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients were randomly assigned (2:1) using an interactive response technology and block randomisation (block size of six) and stratified by progression-free interval after the most recent platinum-containing therapy to receive oral rucaparib (600 mg twice daily administered in 28-day cycles) or chemotherapy on the basis of platinum-sensitivity status. In the chemotherapy group, patients with platinum-resistant disease (progression-free interval ≥1 to <6 months) or partially platinum-sensitive disease (progression-free interval ≥6 to <12 months) received weekly paclitaxel (starting dose 60-80 mg/m2 on days 1, 8, and 15). Patients with fully platinum-sensitive disease (progression-free interval ≥12 months) received the investigator's choice of platinum-based chemotherapy (single-agent cisplatin or carboplatin, or platinum-doublet chemotherapy), in 21-day or 28-day cycles. The primary endpoint (previously reported) was investigator-assessed progression-free survival, assessed in the efficacy population (all randomly assigned patients with deleterious BRCA1 or BRCA2 mutations without reversion mutations) and in the intention-to-treat population (all randomly assigned patients). Overall survival was a prespecified secondary endpoint and was analysed in the intention-to-treat population. Safety was assessed in all patients who received at least one dose of assigned study treatment. The cutoff date was April 10, 2022. This study is registered with ClinicalTrials.gov, NCT02855944; enrolment is complete and the study is closed. FINDINGS: Between March 1, 2017, and Sept 24, 2020, 349 eligible patients were randomly assigned to receive rucaparib (n=233) or chemotherapy (n=116). 332 (95%) of 349 patients were white and 17 (5%) patients were other or of unknown race. In the chemotherapy group, 80 (69%) of 116 patients crossed over to receive rucaparib. Median follow-up was 41·2 months (IQR 37·8-44·6). At data cutoff for this final analysis (April 10, 2022), 244 (70%) of 349 patients had died: 167 (72%) of 233 in the rucaparib group and 77 (66%) of 116 in the rucaparib group. Median overall survival was 19·4 months (95% CI 15·2-23·6) in the rucaparib group versus 25·4 months (21·4-27·6) in the chemotherapy group (hazard ratio 1·3 [95% CI 1·0-1·7], p=0·047). No new safety signals were observed, including during crossover to rucaparib. The most common grade 3-4 adverse events across treatment groups included anaemia or decreased haemoglobin (reported in 59 [25%] of 232 patients in the rucaparib group and seven [6%] of 113 in the chemotherapy group), and neutropenia or decreased neutrophil count (in 26 [11%] of 232 in the rucaparib group and 16 [14%] of 113 patients in the chemotherapy group). Serious adverse events were reported in 66 (28%) of 232 patients in the rucaparib group and 14 (12%) of 113 patients in the chemotherapy group. Ten treatment-related deaths were reported in the rucaparib group, two of which were linked to judged to be related to rucaparib (cardiac disorder and myelodysplastic syndrome), and one death related to treatment was reported in the chemotherapy group, with no specific cause linked to the treatment. INTERPRETATION: These data highlight the need for a better understanding of the most appropriate treatment for patients who have progressed on a poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitor, and the optimal sequencing of chemotherapy and PARP inhibitors in advanced ovarian cancer.

Mismatch repair-deficient (dMMR) endometrial cancer (EC) is an inflamed phenotype with poor outcomes when meeting high-risk criteria and limited treatment options in the adjuvant setting. We report protocol-prespecified subgroup analysis of patients with dMMR tumors from the phase III ENGOT-en11/GOG-3053/KEYNOTE-B21 study (ClinicalTrials.gov identifier: NCT04634877) in newly diagnosed, high-risk EC after surgery with curative intent. Patients were randomly assigned to pembrolizumab 200 mg or placebo (six cycles) plus carboplatin-paclitaxel (four to six cycles) once every 3 weeks, then pembrolizumab 400 mg or placebo once every 6 weeks (six cycles), respectively. MMR status was a stratification factor. Patients received radiotherapy at investigator discretion. Investigator-assessed disease-free survival (DFS) was a primary end point. No formal hypothesis testing was performed for subgroup analysis. In the intention-to-treat population, 141 patients in the pembrolizumab arm and 140 in the placebo arm had dMMR tumors. At this interim analysis, hazard ratio for DFS favored pembrolizumab (0.31 [95% CI, 0.14 to 0.69]); median DFS was not reached in either group. Two-year DFS rates were 92.4% (95% CI, 84.4 to 96.4) and 80.2% (95% CI, 70.8 to 86.9), respectively. No new safety signals occurred. Longer-term follow-up of outcomes will be evaluated at final analysis. Preplanned subgroup analysis on the basis of the study's stratification factors suggests that pembrolizumab plus chemotherapy improves DFS and is clinically relevant for patients with dMMR tumors in the curative-intent setting.

PURPOSE: Patients with high-grade serous ovarian carcinoma (HGSOC) are virtually insensitive to immune checkpoint inhibitors (ICI) employed as standalone therapeutics, at least in part reflecting microenvironmental immunosuppression. Thus, conventional chemotherapeutics and targeted anticancer agents that not only mediate cytotoxic effects but also promote the recruitment of immune effector cells to the HGSOC microenvironment stand out as promising combinatorial partners for ICIs in this oncological indication. EXPERIMENTAL DESIGN: We harnessed a variety of transcriptomic, spatial, and functional assays to characterize the differential impact of neoadjuvant paclitaxel-carboplatin on the immunological configuration of paired primary and metastatic HGSOC biopsies as compared to neoadjuvant chemotherapy (NACT)-naïve HGSOC samples from five independent patient cohorts. RESULTS: We found NACT-driven endoplasmic reticulum stress and calreticulin exposure in metastatic HGSOC lesions culminates with the establishment of a dense immune infiltrate including follicular T cells (TFH cells), a prerequisite for mature tertiary lymphoid structure (TLS) formation. In this context, TLS maturation was associated with an increased intratumoral density of ICI-sensitive TCF1+PD1+ CD8+ T cells over their ICI-insensitive TIM-3+PD1+ counterparts. Consistent with this notion, chemotherapy coupled with a PD1-targeting ICI provided a significant survival benefit over either therapeutic approach in syngeneic models of HGSOC bearing high (but not low) tumor mutational burden. CONCLUSIONS: Altogether, our findings suggest that NACT promotes TLS formation and maturation in HGSOC lesions, de facto preserving an intratumoral ICI-sensitive T-cell phenotype. These observations emphasize the role of rational design, especially relative to the administration schedule, for clinical trials testing chemotherapy plus ICIs in patients with HGSOC.

OBJECTIVES: Part 1 of the RUBY trial (NCT03981796) demonstrated improved survival in patients with primary advanced or recurrent endometrial cancer (EC) treated with dostarlimab plus carboplatin-paclitaxel versus placebo plus carboplatin-paclitaxel. Here, we examine additional efficacy and safety data from patients with mismatch repair deficient/microsatellite instability-high (dMMR/MSI-H) EC in the RUBY trial. METHODS: Patients were randomized 1:1 to dostarlimab 500 mg or placebo plus carboplatin-paclitaxel every 3 weeks for 6 cycles followed by dostarlimab or placebo every 6 weeks for up to 3 years. In the dMMR/MSI-H population of RUBY Part 1, analysis of progression-free survival by investigator assessment compared with blinded independent central review, sensitivity analyses of the source-verified population compared with the randomized population, and analysis of safety in this population were completed. RESULTS: In total, 118 patients with dMMR/MSI-H were enrolled in the RUBY trial (53, dostarlimab arm; 65, placebo arm). At the first interim analysis, a 72% reduction in the risk of progression or death (P < 0.0001) was seen with dostarlimab plus carboplatin-paclitaxel by investigator assessment per Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1), which was consistent with blinded independent central review per RECIST v1.1. Likewise, sensitivity analyses of the source-verified dMMR/MSI-H population compared with the randomized dMMR/MSI-H population were consistent for progression-free survival and overall survival. Safety results seen in the dMMR/MSI-H population were similar to those previously reported for the overall population. CONCLUSIONS: All primary and secondary efficacy assessments demonstrate the consistent benefit of dostarlimab plus carboplatin-paclitaxel. The improvements seen in survival and the manageable safety profile support the favorable benefit-risk profile for dostarlimab plus carboplatin-paclitaxel in patients with dMMR/MSI-H primary advanced or recurrent EC.

BACKGROUND/AIM: Inflammation-based prognostic scores have shown prognostic significance and have been associated with clinical outcomes in various types of cancer. Inflammation is known to promote tumor progression leading to reduced survival. In pancreatic cancer, systemic inflammation is common and contributes to its dismal prognosis. Although the prognosis of pancreatic cancer is improving with the introduction of new drugs, the prognostic indicators are still poorly understood. The present study aimed to evaluate inflammation-based prognostic scores in patients with metastatic pancreatic cancer receiving first-line chemotherapy. PATIENTS AND METHODS: A total of 43 patients with metastatic pancreatic cancer undergoing first-line chemotherapy (gemcitabine+nab-paclitaxel and mFOLFIRINOX) in our institution were analyzed. Baseline clinicopathological and pre-treatment laboratory data were collected. Survival was estimated using the Kaplan-Meier method and survival differences were evaluated using the log-rank test. RESULTS: In the whole cohort, we identified lymphocyte-to-monocyte ratio ≥3, systemic inflammatory response index <2.3, carcinoembryonic antigen <2.5, neutrophil-to-lymphocyte ratio <5, Memorial Sloane Kettering score <2, and prognostic index <2 as prognostic markers associated with improved overall survival in patients receiving first-line chemotherapy. CONCLUSION: The current analysis showed an association between inflammatory-based prognostic markers and overall survival in patients with metastatic pancreatic cancer treated in a real-world setting at a single institution.

Neoadjuvant chemotherapy (NAC) is the preferred treatment option in locally advanced breast cancer (BC). The administration of NAC is associated with a wide range of adverse effects. This pilot observational prospective study examined the effect of NAC using anthracycline + cyclophosphamide (AC) followed by paclitaxel (PTx) on a portfolio of 22 plasma and urinary amino acids, plasma proteins (albumin, prealbumin, transferrin), and products of nitrogen metabolism (urea, creatinine, uric acid) in plasma and urine. Plasma and 24-h urine samples were obtained from ten patients with early breast cancer (N1-3 N0-2 M0), at the following time points: before the start of NAC and during the AC/PTx treatment period (a total of 8 measurements at three-weekly intervals). Amino acids were analyzed using ion exchange chromatography. There were no significant differences in the measured parameters in plasma and urine between pre-NAC and during AC- and PTx-treatment. No trend was detected. A significant difference in the portfolio of plasma and urinary amino acids was found only in the pre-treatment period compared to the control group. Levels of eight plasma amino acids (8/22) were significantly reduced and those of nine urine amino acids were increased (9/22). Nitrogenous catabolites in plasma and urine were not indicative of increased protein catabolism during the anthracycline and taxane treatment periods. A slightly positive nitrogen balance was accompanied by an average weight gain of 3.3 kg (range 0-6 kg). The AC/PTx treatment regimen did not cause significant changes in the monitored laboratory parameters.

Metastatic pancreatic ductal carcinoma (mPDAC) is one of the most lethal malignancies. The European Society for Medical Oncology (ESMO) guidelines recommend a gemcitabine doublet + nab-paclitaxel (Gem/Nab-P) or a modified FOLFIRINOX regimen (mFOLFIRINOX) as options for systemic chemotherapy. Gemcitabine monotherapy is an option for patients in a worse performance status (PS). Indirect comparisons of pivotal trials with Gem/Nab-P and mFOLFIRINOX vs. gemcitabine monotherapy (PRODIGE-4 and MPACT) indicated longer overall survival (OS) in patients treated with mFOLFIRINOX. However, it should be taken into account that the MPACT study with Gem/Nab-P included patients with an overall worse performance status. A direct comparison of these chemotherapy regimens was lacking. Indirect comparisons from real practice show their comparable effectiveness in terms of OS, progression-free survival and overall response rate. The safety profile is consistently different. The recently published phase II/III GENERATE trial, which directly compared Gem/Nab-P and mFOLFIRINOX in treatment-naïve mPDAC patients, demonstrated significantly longer OS in Gem/Nab-P-treated patients exceeding 17 months with a lower incidence of non-hematologic toxicity. The results sparked a lively discussion at the ESMO 2023 Congress. The comparison of Gem/Nab-P and mFOLFIRINOX was also addressed by prof. Prager in his presentation at the PragueONCO 2024 conference. Prager, who highlighted comparable efficacy of both regimens and better safety of Gem/Nab-P and demonstrated the benefit of Gem/Nab-P also in patients older than 70 years and those with Eastern Cooperative Oncology Group (ECOG) performance status (PS) 2. It should also be taken into account that the choice of first line treatment determines the therapeutic options in the 2nd line. If the Gem/Nab-P regimen is used in the first line, pegylated liposomal irinotecan (nal-IRI) in combination with 5-fluorouracil and leucovorin (5-FU/LV) can be used in the second line. This regimen demonstrated prolongation of OS compared to 5-FU/LV in phase III study NAPOLI-1. In patients pretreated with the mFOLFIRINOX regimen, gemcitabine monotherapy or Gem/Nab-P can be used in the second line. Early examination of molecular predictive parameters will enable the identification of cases for which appropriate targeted therapy or immunotherapy is available.

BACKGROUND: Dostarlimab is an immune-checkpoint inhibitor that targets the programmed cell death 1 receptor. The combination of chemotherapy and immunotherapy may have synergistic effects in the treatment of endometrial cancer. METHODS: We conducted a phase 3, global, double-blind, randomized, placebo-controlled trial. Eligible patients with primary advanced stage III or IV or first recurrent endometrial cancer were randomly assigned in a 1:1 ratio to receive either dostarlimab (500 mg) or placebo, plus carboplatin (area under the concentration-time curve, 5 mg per milliliter per minute) and paclitaxel (175 mg per square meter of body-surface area), every 3 weeks (six cycles), followed by dostarlimab (1000 mg) or placebo every 6 weeks for up to 3 years. The primary end points were progression-free survival as assessed by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST), version 1.1, and overall survival. Safety was also assessed. RESULTS: Of the 494 patients who underwent randomization, 118 (23.9%) had mismatch repair-deficient (dMMR), microsatellite instability-high (MSI-H) tumors. In the dMMR-MSI-H population, estimated progression-free survival at 24 months was 61.4% (95% confidence interval [CI], 46.3 to 73.4) in the dostarlimab group and 15.7% (95% CI, 7.2 to 27.0) in the placebo group (hazard ratio for progression or death, 0.28; 95% CI, 0.16 to 0.50; P<0.001). In the overall population, progression-free survival at 24 months was 36.1% (95% CI, 29.3 to 42.9) in the dostarlimab group and 18.1% (95% CI, 13.0 to 23.9) in the placebo group (hazard ratio, 0.64; 95% CI, 0.51 to 0.80; P<0.001). Overall survival at 24 months was 71.3% (95% CI, 64.5 to 77.1) with dostarlimab and 56.0% (95% CI, 48.9 to 62.5) with placebo (hazard ratio for death, 0.64; 95% CI, 0.46 to 0.87). The most common adverse events that occurred or worsened during treatment were nausea (53.9% of the patients in the dostarlimab group and 45.9% of those in the placebo group), alopecia (53.5% and 50.0%), and fatigue (51.9% and 54.5%). Severe and serious adverse events were more frequent in the dostarlimab group than in the placebo group. CONCLUSIONS: Dostarlimab plus carboplatin-paclitaxel significantly increased progression-free survival among patients with primary advanced or recurrent endometrial cancer, with a substantial benefit in the dMMR-MSI-H population.

BACKGROUND: Response to neoadjuvant chemotherapy is associated with improved outcomes for patients with triple negative breast cancer (TNBC). Patients with residual disease are at increased risk of relapse and death from breast cancer. In this retrospective study, we aimed to evaluate the efficacy and safety of cisplatin added to standard neoadjuvant chemotherapy for locally advanced TNBC. MATERIALS AND METHODS: All TNBC treated with neoadjuvant cisplatin 60mg/m2 once in 3 weeks with weekly paclitaxel for 12 weeks, following 8 weeks of dose-dense epirubicin 90mg/m2 or doxorubicin 60mg/m2 with cyclophosphamide 600mg/m2 were analyzed retrospectively. The data related to pathological complete response, adherence to planned therapy, disease-free survival and overall survival were collected. RESULTS: Eighty-three patients were included, of whom 80% had stage III disease. Pathological complete response in both breast (T0/Tis) and axilla (N0) was observed in 48.1% of patients. Miller Payne grade 5 pathological response in the breast was seen in 61% of patients. Good partial responses (Miller Payne grades 3,4) were observed in 32.5% of patients. The remaining 6.5% were poor responders. Seventy-seven patients underwent surgery. The disease-free survival at 1 and 3 years for those who had a pathological complete response was 96.7% and 77.6%, respectively, and 92.3% and 62.7% for those who did not, respectively. The predominant adverse events were hematological, with anemia being the most common one. CONCLUSION: The addition of cisplatin to neoadjuvant chemotherapy with anthracycline and taxane in TNBC was tolerable and produced a high rate of pathological complete response. Cisplatin added to standard chemotherapy in patients with locally advanced TNBC could improve clinical outcomes.
