Bevacizumab, olaparib, and durvalumab in patients with relapsed ovarian cancer: a phase II clinical trial from the GINECO group.

Most patients with advanced ovarian cancer (AOC) ultimately relapse after platinum-based chemotherapy. Combining bevacizumab, olaparib, and durvalumab likely drives synergistic activity. This open-label phase 2 study (NCT04015739) aimed to assess activity and safety of this triple combination in female patients with relapsed high-grade AOC following prior platinum-based therapy. Patients were treated with olaparib (300 mg orally, twice daily), the bevacizumab biosimilar FKB238 (15 mg/kg intravenously, once-every-3-weeks), and durvalumab (1.12 g intravenously, once-every-3-weeks) in nine French centers. The primary endpoint was the non-progression rate at 3 months for platinum-resistant relapse or 6 months for platinum-sensitive relapse per RECIST 1.1 and irRECIST. Secondary endpoints were CA-125 decline with CA-125 ELIMination rate constant K (KELIM-B) per CA-125 longitudinal kinetics over 100 days, progression free survival and overall survival, tumor response, and safety. Non-progression rates were 69.8% (90%CI 55.9%-80.0%) at 3 months for platinum-resistant relapse patients (N = 41), meeting the prespecified endpoint, and 43.8% (90%CI 29.0%-57.4%) at 6 months for platinum-sensitive relapse (N = 33), not meeting the prespecified endpoint. Median progression-free survival was 4.1 months (95%CI 3.5-5.9) and 4.9 months (95%CI 2.9-7.0) respectively. Favorable KELIM-B was associated with better survival. No toxic deaths or major safety signals were observed. Here we show that further investigation of this triple combination may be considered in AOC patients with platinum-resistant relapse.

[French national standard for the treatment of squamous cell carcinoma of upper aero-digestive tract - General principles of treatment]. / Référentiel national de traitement des carcinomes épidermoïdes des voies aérodigestives supérieures ­ Principes généraux de traitement.

OBJECTIVES: The management of upper aerodigestive tract cancers is a complex specialty. It is essential to provide an update to establish optimal care. At the initiative of the INCa and under the auspices of the SFORL, the scientific committee, led by Professor Béatrix Barry, Dr. Gilles Dolivet, and Dr. Dominique De Raucourt, decided to develop a reference framework aimed at defining, in a scientific and consensus-based manner, the general principles of treatment for upper aerodigestive tract cancers applicable to all sub-locations. METHODOLOGY: To develop this framework, a multidisciplinary team of practitioners was formed. A systematic analysis of the literature was conducted to produce recommendations classified by grades, in accordance with the standards of the French National Authority for Health (HAS). RESULTS: The grading of recommendations according to HAS standards has allowed the establishment of a reference for patient care based on several criteria. In this framework, patients benefit from differentiated care based on prognostic factors they present (age, comorbidities, TNM status, HPV status, etc.), conditions of implementation, and quality criteria for indicated surgery (operability, resectability, margin quality, mutilation, salvage surgery), as well as quality criteria for radiotherapy (target volume, implementation time, etc.). The role of medical and postoperative treatments was also evaluated based on specific criteria. Finally, supportive care must be organized from the beginning and throughout the patients' care journey. CONCLUSION: All collected data have led to the development of a comprehensive framework aimed at harmonizing practices nationally, facilitating decision-making in multidisciplinary consultation meetings, promoting equality in practices, and providing a state-of-the-art and reference practices for assessing the quality of care. This new framework is intended to be updated every 5 years to best reflect the latest advances in the field.

Antitumor Activity and Safety of Dostarlimab Monotherapy in Patients With Mismatch Repair Deficient Solid Tumors: A Nonrandomized Controlled Trial.

Importance: Mismatch repair deficiency (dMMR) occurs in various cancers, and these tumors are attractive candidates for anti-programmed cell death 1 therapies, such as dostarlimab, a recently approved immune checkpoint inhibitor. Objective: To assess the antitumor activity and safety of dostarlimab in patients with advanced or recurrent dMMR solid tumors. Design, Setting, And Participants: The GARNET trial was a phase 1, open-label, single-group, multicenter study that began enrolling May 8, 2017. Participants had advanced or recurrent dMMR and microsatellite instability-high (MSI-H) or polymerase epsilon (POLE)-altered solid tumors. The data cut for this interim analysis was from November 1, 2021, with median follow-up of 27.7 months. Interventions: Patients received 500 mg of dostarlimab intravenously every 3 weeks for 4 doses, then 1000 mg every 6 weeks until disease progression, discontinuation, or withdrawal. Main Outcomes and Measures: The primary objective was to evaluate objective response rate and duration of response in patients with dMMR solid tumors by blinded independent central review using Response Evaluation Criteria in Solid Tumors, version 1.1. Results: The efficacy population included 327 patients (median [range] age, 63 [24-85] years; 235 [71.9%] female; 7 [2.1%] Asian, 6 [1.8%] Black, and 206 [63.0%] White patients), with 141 patients (43.1%) with dMMR endometrial cancer, 105 patients (32.1%) with dMMR colorectal cancer, and 81 patients (24.8%) with other dMMR tumor types. All patients had at least 1 previous line of therapy. Objective response rate assessed per blinded independent central review for dMMR solid tumors was 44.0% (95% CI, 38.6% to 49.6%). Median duration of response was not reached (range, ≥1.18 to ≥47.21 months); 72.2% of responders (104 of 144) had a response lasting 12 or more months. Median progression-free survival was 6.9 months (95% CI, 4.2 to 13.6 months); probability of progression-free survival at 24 months was 40.6% (95% CI, 35.0% to 46.1%). Median overall survival was not reached (95% CI, 31.6 months to not reached). The most frequent immune-related adverse events were hypothyroidism (25 [6.9%]), alanine aminotransferase increase (21 [5.8%]), and arthralgia (17 [4.7%]). No new safety concerns were identified. Conclusions And Relevance: In this nonrandomized controlled trial, dostarlimab was a well-tolerated treatment option with rapid, robust, and durable antitumor activity in patients with diverse dMMR solid tumors. These findings suggest that dostarlimab provides meaningful long-term benefit in a population with high unmet need. Trial Registration: ClinicalTrials.gov Identifier: NCT02715284.

PARP inhibitors (PARPi) prolongation after local therapy for oligo-metastatic progression in relapsed ovarian cancer patients.

BACKGROUND: PARP inhibitors (PARPi) have revolutionized the management of high-grade epithelial ovarian cancer (HGOC) treatment. However, a significant number of patients relapse or progress under PARPi, leading to the introduction of a new line of systemic therapy such as chemotherapy. In patients with a limited number of metastatic sites at progression, -referred to as an oligometastatic progression- a potential indication for local therapy followed by re-introduction or continuation of PARPi treatment rather than initiating a new line of chemotherapy could be proposed. However, the impact of such strategies on progression free survival (PFS) in these patients remains unknown. METHODS: This international multicenter retrospective study evaluated the efficacy of PARPi continuation or re-introduction in patients with HGOC after local treatment for oligometastatic progression. The main objective was to assess PFS under PARPi after local therapy (PFS post-LT). Secondary objectives included safety and overall survival (OS). RESULTS: 74 patients were identified in 20 centers between April 2020 and November 2021. 65% of patients were BRCA mutated and 92% had received ≥2 lines of prior systemic chemotherapy before the initial introduction of PARPi. Main progression sites were lymph nodes (42%), peritoneum (27%), liver (16%), other visceral (16%) and abdominal wall (4%). Local therapies included radiotherapy (45%), surgery (43%), both (7%), percutaneous thermal ablation (4%) or chemoembolization (1%). Median PFS post-LT was 11.5 months [95% CI 7.4; 17.2]. After a median follow up of 14.8 months, 6 patients (8.1%) discontinued PARPi due to toxicity. The 1-year overall survival rate was 90.7% [95% CI 79.1; 96.0]. CONCLUSIONS: With close to one year without progression or introduction of a new line of systemic therapy, this study reports the feasibility and potential benefit of this original strategy in patients with oligometastatic progression under PARPi.

The promising prognostic value of vagal nerve activity at the initial management of ovarian cancer.

Objective: Identifying new modifiable prognostic markers is important for ovarian cancer (OC). Low parasympathic activity is associated with inflammation, oxidative stress and sympathetic nervous system activation. Previous studies reported that low vagal nerve activity, measured by low heart rate variability (HRV), may predict poor cancer prognosis. We aimed to examine the prognostic value of HRV in OC. Methods: This bicentric retrospective study included patients diagnosed with serous OC FIGO stage ≥IIB, between January 2015 and August 2019, with electrocardiograms (ECG) available around diagnosis. HRV was measured from ECG using the time domain parameter of standard deviation of all normal-to-normal heartbeat intervals (SDNN). Optimal SDNN cut-off was determined using the Youden index criteria of time-dependent ROC curves. We used multivariate cox proportional hazard models to investigate the association between HRV and overall survival (OS), while adjusting for well-known OC prognostic factors. Results: The 202 patients included were 65.7 years-old on average, 93% had stage FIGO IIIC/IV, 56% had complete surgical resection. Median OS was 38.6 months [95%CI:34.4-47.4]. The median SDNN was 11.1ms, with an optimal cut-off of 10ms to predict OS. OS was shorter for patients with low HRV compared to high HRV (26.4 vs 45.1 months; p<0.001). In multivariate analysis, HRV remained an independent prognostic factor with a two-fold higher risk of death among patients with low SDNN compared to those with high SDNN (HR=2.03, 95%CI=1.35-3.06, p<0.001). Conclusion: Low HRV, was associated with worse OS in OC patients, supporting previous studies on the prognostic role of HRV in cancer. If replicated in prospective studies, vagal nerve activity may be a new therapeutic target in OC.

Paclitaxel with or without pazopanib for ovarian cancer relapsing during bevacizumab maintenance therapy: The GINECO randomized phase II TAPAZ study.

BACKGROUND: Anti-angiogenic rechallenge with bevacizumab plus chemotherapy is effective in recurrent ovarian cancer (rOC); however, data are limited on tyrosine kinase inhibitors after progression on maintenance bevacizumab. METHODS: In the randomized phase II TAPAZ trial, patients with rOC during the first year of bevacizumab maintenance therapy were assigned 2:1 to either weekly paclitaxel 65 mg/m2 plus pazopanib 600-800 mg daily or standard weekly paclitaxel 80 mg/m2. The primary endpoint was 4-month progression-free survival (PFS) rate. RESULTS: Overall, 116 patients were randomized and treated: 79 with combination therapy and 37 with single-agent paclitaxel. Median follow-up was 13.1 months. There was no difference between treatment arms in 4-month PFS rate (61% [95% CI, 51-73%] with the combination versus 68% [95% CI, 54-85%] with paclitaxel alone), median PFS (4.9 [95% CI, 4.1-6.1] versus 5.8 [95% CI, 4.8-7.4] months, respectively) or median overall survival (13.6 versus 12.9 months, respectively). The combination was associated with more grade 3/4 toxicities (87% versus 70%, respectively) and toxicity-related paclitaxel discontinuations (22% versus 11%). Pazopanib was discontinued for toxicity in 44% of patients, most commonly for gastrointestinal and vascular events. There were two treatment-related deaths, both in the combination arm (pulmonary embolism and gastrointestinal perforation). At month 4, patient-reported outcomes deteriorated from baseline in the combination arm, particularly for abdominal/gastrointestinal symptoms, which showed a clinically important difference versus paclitaxel alone. CONCLUSIONS: In rOC progressing during maintenance bevacizumab, adding pazopanib to paclitaxel did not improve efficacy, increased toxicity, and compromised chemotherapy delivery.

Safety and Efficacy of the mTOR Inhibitor, Vistusertib, Combined With Anastrozole in Patients With Hormone Receptor-Positive Recurrent or Metastatic Endometrial Cancer: The VICTORIA Multicenter, Open-label, Phase 1/2 Randomized Clinical Trial.

Importance: Endometrial cancer is often hormone-dependent and treated with aromatase inhibitors. The PI3K-AKT-mTOR pathway deregulation observed in endometrial cancer drives hormonal resistance, thus supporting the rationale of combining mTOR inhibitor with endocrine therapy. Objective: To evaluate the safety and efficacy of vistusertib in combination with anastrozole in the treatment of women with hormone receptor-positive recurrent or metastatic endometrial cancer. Design, Settings, and Participants: The VICTORIA study was a multicenter, open-label, randomized clinical trial that accrued 75 patients with hormone receptor-positive recurrent or metastatic endometrial cancer from 12 cancer centers in France in April 2016 to October 2019. After a safety run-in period, a Simon 2-stage design was used. Data analyses were performed from December 11, 2020, to March 11, 2021. Interventions: Patients were randomized in a 2:1 ratio to oral vistusertib (125 mg twice daily 2 days per week) and oral anastrozole (1 mg daily) in the combination vistusertib with anastrozole arm (V+A arm) or oral anastrozole alone (A arm). Main Outcomes and Measures: The primary end point was serious adverse events for the safety run-in period and progression-free rate at 8 weeks (8wk-PFR)-assessed with a blinded independent central review in phase 2. The secondary end points were objective response rate, duration of response, progression-free survival (PFS), overall survival, and incidence of adverse events. Results: Of the 75 patients who were randomized, 73 (median [range] age, 69.5 [37-88] y; all female) were treated: V+A arm, 49 patients; A arm, 24 patients. In the V+A arm, the 8wk-PFR was 67.3% (unilateral 95% CI, 54.7%) and in the A arm, 39.1% (unilateral 95% CI, 22.2%). No significant serious adverse events were reported during the safety run-in period (n = 6 in V+A arm). The overall response rate was 24.5% (95% CI, 13.3%-38.9%) in the V+A arm vs 17.4% (95% CI, 5.0%-38.8%) in the A arm. With a median follow-up of 27.7 months, median PFS was 5.2 (95% CI, 3.4-8.9) in the V+A arm and 1.9 (95% CI, 1.6-8.9) months in the A arm. Fatigue, lymphopenia, hyperglycemia, and diarrhea were the most common (grade ≥2) adverse events associated with vistusertib. Conclusions and Relevance: This multicenter, open-label, phase 1/2 randomized clinical trial demonstrated that adding vistusertib to anastrozole improved 8wk-PFR, overall response rate, and PFS for patients with endometrial cancer and had manageable adverse events. Identification of molecular subgroups would allow for more precise selection of patients who may be most likely to experience favorable outcomes.

Regorafenib or Tamoxifen for platinum-sensitive recurrent ovarian cancer with rising CA125 and no evidence of clinical or RECIST progression: A GINECO randomized phase II trial (REGOVAR).

OBJECTIVE: To evaluate the efficacy and safety of regorafenib versus tamoxifen in platinum-sensitive ovarian cancer biological recurrence, defined by CA-125 increase without radiological (RECIST criteria) or symptomatic evidence of progression. PATIENTS AND METHODS: 116 patients with platinum-sensitive ovarian cancer presenting an isolated increase of CA-125 were planned to be randomized. Regorafenib was administered orally at 160 or 120 mg daily, 3 weeks on/1 week off or tamoxifen at 40 mg daily, until disease progression or development of unacceptable toxicity. The primary endpoint was Progression-Free Survival, assessed by progression according to RECIST 1.1 or death (by any cause). Secondary endpoints included Overall Survival, Best Response and CA-125 response rate. RESULTS: 68 patients were randomized. Median age was 67 years (range: 30-87). Primary site of cancer was ovarian for most patients (92.6%). Tumors were predominantly serous / (89.7%), high grade (83.6%) and initial FIGO staging was III for 69.6% of the patients. Most (79.4%) patients were included after the first line of platinum-based treatment. After a median follow-up of 32 months, there was no difference of progression-free survival (PFS) between regorafenib and tamoxifen groups (p = 0.72), with median PFS of 5.6 months (CI 90%: 3.84-7.52) for the tamoxifen arm and 4.6 months (CI 90%: 3.65-7.33) for the regorafenib arm. There was also no difference in term of overall survival, best response or CA-125 response, delay to next therapy. Regorafenib presented a less favorable safety profile than tamoxifen, with grade 3/4 events occurring for 90.9% of the patients compared to 54.3% for tamoxifen. The most frequent were cutaneous, digestive, and biological events. Notably, hand-foot syndrome occurred in 36.4% of these patients. CONCLUSION: Regorafenib presented an unfavorable toxicity profile compared to tamoxifen, with no superior efficacy in this population of patients.

Impact of previous nivolumab treatment on the response to taxanes in patients with recurrent/metastatic head and neck squamous cell carcinoma.

BACKGROUND: Immune checkpoint inhibitors are widely used in recurrent and/or metastatic head and neck squamous cell carcinoma (R/M HNSCC). We aimed to describe response rates to taxanes after progression on nivolumab in R/M HNSCC patients. METHODS: In this multicentric retrospective comparative study, we included patients treated with taxane monotherapy from 2014 to 2020. Patients were divided into two groups depending on whether they received nivolumab before taxanes (post-nivolumab group) or not (control group). The primary end-point was objective response rate (ORR) comparison between the two groups. The secondary end-points included disease control rate (DCR), progression-free survival (PFS), overall survival (OS), and PFS ratio (PFSr=PFS associated with taxanes divided by PFS associated with the previous line of treatment), a survival marker used for comparison of different treatment lines. RESULTS: Between July 2014 and August 2020, 185 patients were included (114 in the control group and 71 in the post-nivolumab group). ORR was significantly higher in the post-nivolumab group (39.4% versus 26.3%, p = 0.03) as was DCR (69% versus 50%, P = 0.06). The median OS (7.5 months) and PFS (3.5 months) were not significantly different in the two groups, whereas PFSr was significantly improved in the post-nivolumab group (1.63 versus 1.11, P = 0.004). CONCLUSION: Response and DCRs with taxanes are improved after prior exposure to nivolumab. Thus, taxane monotherapy could be a good choice as third-line therapy after nivolumab following a platinum-based first line. These results currently apply to patients without access to or potential benefit from first-line pembrolizumab.

A New Paradigm in Managing Advanced Ovarian Cancer: Differentiating Patients Requiring Neoadjuvant Treatment from Primary Cytoreduction.

Our study aims to evaluate the comparability of primary debulking surgery (PDS) and neoadjuvant chemotherapy (NACT) patients. This single-center retrospective study includes all patients treated for advanced stages high-grade serous ovarian carcinomas (HGSOC) between 2007 and 2017. Preoperative characteristics and postoperative outcomes were compared after a propensity score matching analysis. Of the 221 patients included, 38% underwent PDS, and 62% received NACT. There was no age difference at diagnosis; however, CA125 levels, PCI score levels, and rates of stage IV were higher in the NACT group. There were no differences concerning the rate and the severity of complications (p = 0.29). The propensity score distribution showed a broad distinction between PDS patients and NACT patients with no significant overlap. Survival analyses demonstrate, after a median follow-up of 66.5 months, an overall survival (OS) of 105.9 and progression-free survival (PFS) of 29.2 months in the PDS group, compared to OS of 52.8 and PFS of 18.9 months in the NACT group. Advanced HGSOC is a heterogeneous population, in which inoperable patients should be differentiated from PDS patients based on many factors, primarily tumor burden.

Prognostic factor analysis and long-term results of the TAX 323 (EORTC 24971) study in unresectable head and neck cancer patients.

BACKGROUND: In the TAX 323 (EORTC 24971) phase III trial enrolling patients with unresectable locoregionally advanced squamous cell carcinoma of the head and neck (LA-SCCHN), the addition of docetaxel (T) to cisplatin and 5-fluorouracil (PF)-based induction chemotherapy prior to definite radiotherapy significantly improved progression-free survival (PFS) and overall survival (OS). METHODS: The data were updated for PFS, OS and treatment-related long-term side-effects. Baseline clinical and laboratory data of 17 variables were collected and subjected to univariate and multivariate prognostic factor analyses for OS. RESULTS: All 358 patients randomised between 1999 and 2002 were included in the long-term analysis with a median follow-up of 8.6 years. The primary end-point of PFS remained significantly improved with TPF compared with PF (adjusted hazard ratio [HR], 0.70; 95% CI, 0.56-0.88, p = 0.002), translating into a persisting benefit in OS (adjusted HR, 0.75; 95% CI, 0.60-0.95, p = 0.015). Long-term side-effects in the TPF/PF arms comprised tracheostomy (7%/5%), feeding tube dependency (3%/6%) and gastrostomy (11%/11%). Second malignancy occurred in 8%/3%, respectively. Out of 177 patients randomised to the TPF arm, 160 were included in the multivariate analysis. Grade 2 or more dysphagia (p = 0.002) and grade 2 or more pain (p = 0.004) at baseline were identified as independent negative prognostic factors. In addition, OS differed across primary tumour sites (p = 0.027) and was worse in patients with a higher N-stage (p = 0.025). CONCLUSIONS: In LA-SCCHN patients treated with sequential chemoradiotherapy, TPF induction chemotherapy demonstrated long-lasting efficacy, superior to the PF regimen. Higher-grade dysphagia and pain are unfavourable prognosticators.

Clinical activity and safety of the anti-PD-1 monoclonal antibody dostarlimab for patients with recurrent or advanced dMMR endometrial cancer.

This document provides a short summary of the GARNET trial which was published in JAMA Oncology in October 2020. At the end of this document, there are links to websites where you can find more information about this study. The trial enrolled adult participants with advanced solid tumors. This report is restricted to patients with a particular type of endometrial cancer that has a deficient mismatch repair (dMMR) status. Patients received a trial treatment called dostarlimab (also known by the brand name Jemperli). In the US, dostarlimab is approved as a single therapy in adult patients with dMMR recurrent or advanced endometrial cancer that has progressed on or after platinum-based chemotherapy. In the EU, dostarlimab is approved as a single therapy in adult patients with recurrent or advanced dMMR/microsatellite instability-high (MSI-H) endometrial cancer that has progressed on or after treatment with a platinum-containing regimen. The GARNET trial looked at dostarlimab given intravenously to patients with dMMR endometrial cancer from 7 countries. The trial showed that dostarlimab was successful in shrinking the tumor in 42% of these patients. In general, the percentage of participants who experienced medical problems (referred to as side effects) was low and within expectations for this type of treatment.

Clinical Activity and Safety of the Anti-Programmed Death 1 Monoclonal Antibody Dostarlimab for Patients With Recurrent or Advanced Mismatch Repair-Deficient Endometrial Cancer: A Nonrandomized Phase 1 Clinical Trial.

IMPORTANCE: Deficient mismatch mutation repair mechanisms may sensitize endometrial cancers to anti-programmed death 1 (PD-1) therapies. Dostarlimab (TSR-042) is an investigational anti-PD-1 antibody that binds with high affinity to the PD-1 receptor. OBJECTIVE: To assess the antitumor activity and safety of dostarlimab for patients with deficient mismatch repair endometrial cancer. DESIGN, SETTING, AND PARTICIPANTS: This ongoing, open-label, single-group, multicenter study began part 1 on March 7, 2016, and began enrolling patients with deficient mismatch mutation repair endometrial cancer on May 8, 2017. Median follow-up was 11.2 months (range, 0.03 [ongoing] to 22.11 [ongoing] months; based on radiological assessments). Statistical analysis was performed July 8 to August 9, 2019. INTERVENTIONS: Patients received 500 mg of dostarlimab intravenously every 3 weeks for 4 doses, then 1000 mg every 6 weeks until disease progression, treatment discontinuation, or withdrawal. MAIN OUTCOMES AND MEASURES: The primary end point was objective response rate and duration of response by blinded independent central review using Response Evaluation Criteria in Solid Tumors, version 1.1. RESULTS: As of the data cutoff, 104 women (median age, 64.0 years [range, 38-80 years]) with deficient mismatch mutation repair endometrial cancers were enrolled and treated with dostarlimab. Of these, 71 had measurable disease at baseline and at 6 months or more of follow-up and were included in the analysis. There was a confirmed response in 30 patients (objective response rate, 42.3%; 95% CI, 30.6%-54.6%); 9 patients (12.7%) had a confirmed complete response, and 21 patients (29.6%) had a confirmed partial response. Responses were durable; the median duration of response was not reached (median follow-up was 11.2 months). The estimated likelihood of maintaining a response was 96.4% at 6 months and 76.8% at 12 months. Anemia (3 of 104 [2.9%]), colitis (2 of 104 [1.9%]), and diarrhea (2 of 104 [1.9%]) were the most common grade 3 or higher treatment-related adverse events. CONCLUSIONS AND RELEVANCE: In this nonrandomized trial, dostarlimab was associated with clinically meaningful and durable antitumor activity with an acceptable safety profile for patients with deficient mismatch mutation repair endometrial cancers after prior platinum-based chemotherapy.
