Glofitamab monotherapy induces durable remission in patients with relapsed or refractory diffuse large B-cell lymphoma after two or more previous therapies, but has not previously been assessed as a second-line therapy. We investigated the efficacy and safety of glofitamab plus gemcitabine–oxaliplatin (Glofit-GemOx) versus rituximab (R)-GemOx in patients with relapsed or refractory diffuse large B-cell lymphoma. The phase 3, randomised, open-label STARGLO trial was done at 62 centres in 13 countries in Asia and Australia, Europe, and North America. We recruited transplant-ineligible patients (aged ≥18 years) with histologically confirmed relapsed or refractory diffuse large B-cell lymphoma after one or more previous therapies. Patients were randomly assigned in permuted blocks (block size of six) via an interactive voice or web response system (2:1; stratified by 1 vs ≥2 previous lines of therapy and relapsed vs refractory status) to Glofit-GemOx (intravenous gemcitabine 1000 mg/m2 and oxaliplatin 100 mg/m2 plus glofitamab step-up dosing to 30 mg; for a total of eight cycles, plus four additional cycles of glofitamab monotherapy) or R-GemOx (intravenous gemcitabine 1000 mg/m2 and oxaliplatin 100 mg/m2 plus rituximab 375 mg/m2; for a total of eight cycles). The trial independent review committee, which evaluated all response-based endpoints, was masked to treatment assignment. The primary endpoint was overall survival. Efficacy analyses were by intention to treat in all randomly assigned patients. We present results from both the primary analysis (cutoff: March 29, 2023) and updated analysis after all patients had completed study therapy (cutoff: Feb 16, 2024). Safety analyses included all patients who received any study treatment. This study is registered with ClinicalTrials.gov, NCT04408638, and is ongoing (closed to recruitment). From Feb 23, 2021, to March 14, 2023, 274 patients were enrolled and randomly assigned to receive Glofit-GemOx (n=183) or R-GemOx (n=91). 158 (58%) patients were male and 116 (42%) were female; median age was 68 years (IQR 58–74). At the primary analysis after a median follow-up of 11·3 months (95% CI 9·6–12·7), overall survival was significantly improved with Glofit-GemOx versus R-GemOx (median not estimable [NE; 95% CI 13·8 months–NE] vs 9·0 months [7·3–14·4]; hazard ratio [HR] 0·59 [95% CI 0·40–0·89]; p=0·011). At the updated analysis after a median follow-up of 20·7 months (19·9–23·3), a consistent improvement in overall survival was observed with Glofit-GemOx versus R-GemOx (median 25·5 months [18·3–NE] vs 12·9 months [7·9–18·5]; HR 0·62 [0·43–0·88]). In the safety sets, 180 (100%) patients in the Glofit-GemOx group and 84 (96%) of 88 patients in the R-GemOx group had at least one adverse event during the study period. Cytokine release syndrome occurred in 76 (44%) of 172 glofitamab-exposed patients and was predominantly low grade. Deaths related to glofitamab or rituximab occurred in five (3%) patients in the Glofit-GemOx group and in one (1%) patient in the R-GemOx group. Glofit-GemOx had a significant overall survival benefit compared with R-GemOx, supporting its use in transplant-ineligible patients with relapsed or refractory diffuse large B-cell lymphoma after one or more previous lines of therapy.

Treatment of locally advanced rectal cancer with chemoradiotherapy, surgery, and adjuvant chemotherapy controls local disease, but distant metastases remain common. We aimed to assess whether administering neoadjuvant chemotherapy before preoperative chemoradiotherapy could reduce the risk of distant recurrences. We did a phase 3, open-label, multicentre, randomised trial at 35 hospitals in France. Eligible patients were adults aged 18–75 years and had newly diagnosed, biopsy-proven, rectal adenocarcinoma staged cT3 or cT4 M0, with a WHO performance status of 0–1. Patients were randomly assigned (1:1) to either the neoadjuvant chemotherapy group or standard-of-care group, using an independent web-based system by minimisation method stratified by centre, extramural extension of the tumour into perirectal fat according to MRI, tumour location, and stage. Investigators and participants were not masked to treatment allocation. The neoadjuvant chemotherapy group received neoadjuvant chemotherapy with FOLFIRINOX (oxaliplatin 85 mg/m2, irinotecan 180 mg/m2, leucovorin 400 mg/m2, and fluorouracil 2400 mg/m2 intravenously every 14 days for 6 cycles), chemoradiotherapy (50 Gy during 5 weeks and 800 mg/m2 concurrent oral capecitabine twice daily for 5 days per week), total mesorectal excision, and adjuvant chemotherapy (3 months of modified FOLFOX6 [intravenous oxaliplatin 85 mg/m2 and leucovorin 400 mg/m2, followed by intravenous 400 mg/m2 fluorouracil bolus and then continuous infusion at a dose of 2400 mg/m2 over 46 h every 14 days for six cycles] or capecitabine [1250 mg/m2 orally twice daily on days 1–14 every 21 days]). The standard-of-care group received chemoradiotherapy, total mesorectal excision, and adjuvant chemotherapy (for 6 months). The primary endpoint was disease-free survival assessed in the intention-to-treat population at 3 years. Safety analyses were done on treated patients. This trial was registered with EudraCT (2011-004406-25) and ClinicalTrials.gov (NCT01804790) and is now complete. Between June 5, 2012, and June 26, 2017, 461 patients were randomly assigned to either the neoadjuvant chemotherapy group (n=231) or the standard-of-care group (n=230). At a median follow-up of 46·5 months (IQR 35·4–61·6), 3-year disease-free survival rates were 76% (95% CI 69–81) in the neoadjuvant chemotherapy group and 69% (62–74) in the standard-of-care group (stratified hazard ratio 0·69, 95% CI 0·49–0·97; p=0·034). During neoadjuvant chemotherapy, the most common grade 3–4 adverse events were neutropenia (38 [17%] of 225 patients) and diarrhoea (25 [11%] of 226). During chemoradiotherapy, the most common grade 3–4 adverse event was lymphopenia (59 [28%] of 212 in the neoadjuvant chemotherapy group vs 67 [30%] of 226 patients in the standard-of-care group). During adjuvant chemotherapy, the most common grade 3–4 adverse events were lymphopenia (18 [11%] of 161 in the neoadjuvant chemotherapy group vs 42 [27%] of 155 in the standard-of-care group), neutropenia (nine [6%] of 161 vs 28 [18%] of 155), and peripheral sensory neuropathy (19 [12%] of 162 vs 32 [21%] of 155). Serious adverse events occurred in 63 (27%) of 231 participants in the neoadjuvant chemotherapy group and 50 (22%) of 230 patients in the standard-of-care group (p=0·167), during the whole treatment period. During adjuvant therapy, serious adverse events occurred in 18 (11%) of 163 participants in the neoadjuvant chemotherapy group and 36 (23%) of 158 patients in the standard-of-care group (p=0·0049). Treatment-related deaths occurred in one (<1%) of 226 patients in the neoadjuvant chemotherapy group (sudden death) and two (1%) of 227 patients in the standard-of-care group (one sudden death and one myocardial infarction). Intensification of chemotherapy using FOLFIRINOX before preoperative chemoradiotherapy significantly improved outcomes compared with preoperative chemoradiotherapy in patients with cT3 or cT4 M0 rectal cancer. The significantly improved disease-free survival in the neoadjuvant chemotherapy group and the decreased neurotoxicity indicates that the perioperative approach is more efficient and better tolerated than adjuvant chemotherapy. Therefore, the PRODIGE 23 results might change clinical practice. Institut National du Cancer, Ligue Nationale Contre le Cancer, and R&D Unicancer.

In a trial comparing preoperative chemoradiotherapy and FOLFOX in patients with rectal cancer undergoing sphincter-sparing surgery, 5-year disease-free survival was 80.8% with FOLFOX and 78.6% with chemoradiotherapy.

In resectable gastric and gastroesophageal junction cancer, adding durvalumab to perioperative chemotherapy improved event-free survival and pathological complete response, with no major increase in high-grade adverse events.

Docetaxel-based chemotherapy is effective in metastatic gastric and gastro-oesophageal junction adenocarcinoma. This study reports on the safety and efficacy of the docetaxel-based triplet FLOT (fluorouracil plus leucovorin, oxaliplatin and docetaxel) as a perioperative therapy for patients with locally advanced, resectable tumours. In this controlled, open-label, phase 2/3 trial, we randomly assigned 716 patients with histologically-confirmed advanced clinical stage cT2 or higher or nodal positive stage (cN+), or both, resectable tumours, with no evidence of distant metastases, via central interactive web-based-response system, to receive either three pre-operative and three postoperative 3-week cycles of 50 mg/m2 epirubicin and 60 mg/m2 cisplatin on day 1 plus either 200 mg/m2 fluorouracil as continuous intravenous infusion or 1250 mg/m2 capecitabine orally on days 1 to 21 (ECF/ECX; control group) or four preoperative and four postoperative 2-week cycles of 50 mg/m2 docetaxel, 85 mg/m2 oxaliplatin, 200 mg/m2 leucovorin and 2600 mg/m2 fluorouracil as 24-h infusion on day 1 (FLOT; experimental group). The primary outcome of the trial was overall survival (superiority) analysed in the intention-to-treat population. This trial is registered with ClinicalTrials.gov, number NCT01216644. Between Aug 8, 2010, and Feb 10, 2015, 716 patients were randomly assigned to treatment in 38 German hospitals or with practice-based oncologists. 360 patients were assigned to ECF/ECX and 356 patients to FLOT. Overall survival was increased in the FLOT group compared with the ECF/ECX group (hazard ratio [HR] 0·77; 95% confidence interval [CI; 0.63 to 0·94]; median overall survival, 50 months [38·33 to not reached] vs 35 months [27·35 to 46·26]). The number of patients with related serious adverse events (including those occurring during hospital stay for surgery) was similar in the two groups (96 [27%] in the ECF/ECX group vs 97 [27%] in the FLOT group), as was the number of toxic deaths (two [<1%] in both groups). Hospitalisation for toxicity occurred in 94 patients (26%) in the ECF/ECX group and 89 patients (25%) in the FLOT group. In locally advanced, resectable gastric or gastro-oesophageal junction adenocarcinoma, perioperative FLOT improved overall survival compared with perioperative ECF/ECX.

The best multimodal approach for resectable locally advanced esophageal adenocarcinoma is unclear. An important question is whether perioperative chemotherapy is preferable to preoperative chemoradiotherapy. In this phase 3, multicenter, randomized trial, we assigned in a 1:1 ratio patients with resectable esophageal adenocarcinoma to receive perioperative chemotherapy with FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) plus surgery or preoperative chemoradiotherapy (radiotherapy at a dose of 41.4 Gy and carboplatin and paclitaxel) plus surgery. Eligibility criteria included a primary tumor with a clinical stage of cT1 cN+, cT2-4a cN+, or cT2-4a cN0 disease, in which T indicates the size and extent of the tumor (higher numbers indicate a more advanced tumor), and N indicates the presence (N+) or absence (N0) of cancer spread to the lymph nodes, without evidence of metastatic spread. The primary end point was overall survival. From February 2016 through April 2020, we assigned 221 patients to the FLOT group and 217 patients to the preoperative-chemoradiotherapy group. With a median follow-up of 55 months, overall survival at 3 years was 57.4% (95% confidence interval [CI], 50.1 to 64.0) in the FLOT group and 50.7% (95% CI, 43.5 to 57.5) in the preoperative-chemoradiotherapy group (hazard ratio for death, 0.70; 95% CI, 0.53 to 0.92; P = 0.01). Progression-free survival at 3 years was 51.6% (95% CI, 44.3 to 58.4) in the FLOT group and 35.0% (95% CI, 28.4 to 41.7) in the preoperative-chemoradiotherapy group (hazard ratio for disease progression or death, 0.66; 95% CI, 0.51 to 0.85). Among the patients who started the assigned treatment, grade 3 or higher adverse events were observed in 120 of 207 patients (58.0%) in the FLOT group and in 98 of 196 patients (50.0%) in the preoperative-chemoradiotherapy group. Serious adverse events were observed in 98 of 207 patients (47.3%) in the FLOT group and in 82 of 196 patients (41.8%) in the preoperative-chemoradiotherapy group. Mortality at 90 days after surgery was 3.1% in the FLOT group and 5.6% in the preoperative-chemoradiotherapy group. Perioperative chemotherapy with FLOT led to improved survival among patients with resectable esophageal adenocarcinoma as compared with preoperative chemoradiotherapy.

This study aims to compare the safety and efficiency of modified biweekly CAPOX and conventional triweekly CAPOX in high-risk stage II and stage III post-surgery colorectal (CRC) patients. From July 25, 2018, to May 14, 2021, high-risk stage II and stage III post-surgery CRC patients were randomized in the control triweekly group (intravenous infusion of oxaliplatin 130 mg/m2 on day 1 and oral capecitabine 1000 mg/m2, twice daily from day 1 to day 14) and the experimental biweekly group (intravenous infusion of oxaliplatin 85 mg/m2 on day 1 and oral capecitabine 1000 mg/m2, twice daily from day 1 to day 10). The primary endpoint was the incidence rate of thrombocytopenia. The secondary endpoint was 3-year disease free survival (DFS) rate. The patients follow up was started on July 25, 2018, and finished on October 8, 2024. A total of 160 patients were 1:1 randomly assigned (80 patients to biweekly group and 80 patients to triweekly group). All grade thrombocytopenia occurred in 33% and 49% patients at biweekly and triweekly group, respectively (P = 0.02). Neutropenia presented in 36% and 51% patients at biweekly and triweekly group, respectively (P = 0.04). The second endpoint 3-year DFS was 85.1% in biweekly group and 80.4% in triweekly CAPOX group (P = 0.51, HR = 0.78, [95%CI, 0.38-1.63]). The total rate of uncomplete therapy patient was 7.5% and 15% in biweekly and triweekly group, respectively (P = 0.13). Biweekly CAPOX presented significant less thrombocytopenia and neutropenia than triweekly CAPOX regimen. There was no difference in 3-year DFS between biweekly CAPOX and triweekly CAPOX.

Abstract Background New therapeutic options are needed for biliary tract cancer (BTC). Regorafenib, a multikinase inhibitor, shows promise in refractory digestive cancers and may be beneficial with conventional chemotherapy for BTC. Patients and Methods The BREGO study evaluated regorafenib with modified gemcitabine-oxaliplatin (mGEMOX) in advanced or metastatic BTC. Phase I determined the recommended dose (RP2D) of regorafenib (80, 120 or 160 mg, days 1-14) combined with mGEMOX (gemcitabine 900 mg.m−2 IV, 30 min, followed by oxaliplatin 80mg.m−2 IV, 120 min, days 1 and 8). Phase II randomized (1:2) patients to mGEMOX alone (arm A) or mGEMOX + regorafenib (arm B, RP2D, days 1-14), assessing efficacy and safety, with the primary outcome being progression-free survival (PFS). Metabolic tumor features and response were also assessed. Results In phase Ib, 22 patients were enrolled; in phase II, 66 patients (arm A, n = 24; arm B, n = 42). Four dose-limiting toxicities were observed, but no maximum tolerated dose was reached. The RP2D was 160 mg.d−1. Median PFS (7.2 vs7.8 months; P = .825) and overall survival (15.1 vs 13.5 months; P = .356) were similar between arms. However, posttreatment 18F-FDG tumor uptake (SULpeak) significantly correlated with PFS (P = .001) and OS (P = .016). Baseline plasma stanniocalcin 1 levels < 265 pg.mL−1 were associated with longer PFS (P = .030) and OS (P = .060) in both arms. Conclusions Combining regorafenib and mGEMOX is feasible as first-line treatment for BTC but did not increase PFS as expected in the phase II cohort. Identifying new biomarkers can help target patients with advanced BTCs who may benefit from regorafenib-associated therapy. Trial registration number ClinicalTrials.gov, NCT02386397.

The PREOPANC-2 trial aimed to evaluate whether neoadjuvant FOLFIRINOX improved overall survival compared with neoadjuvant gemcitabine-based chemoradiotherapy followed by adjuvant gemcitabine in patients with resectable or borderline resectable pancreatic ductal adenocarcinoma (PDAC). In this investigator-initiated, open-label, nationwide, phase 3 randomised trial, patients aged 18 years or older with resectable or borderline resectable PDAC and a WHO performance status of 0 or 1 were enrolled across 19 Dutch centres. Patients in the FOLFIRINOX (FFX) group received FOLFIRINOX (85 mg/m2 intravenous oxaliplatin, 180 mg/m2 intravenous irinotecan, 400 mg/m2 intravenous leucovorin, followed by a 400 mg/m2 intravenous fluorouracil bolus and then continuous infusion at 2400 mg/m2 intravenously over 46 h every 14 days for eight cycles) followed by surgery without adjuvant treatment. Patients in the chemoradiotherapy (CRT) group received three cycles of neoadjuvant gemcitabine (1000 mg/m2 intravenously on days 1, 8, and 15 of each 28-day cycle and on days 1 and 8 only for cycles one and three) combined with hypofractionated radiotherapy (36 Gy in 15 fractions) during the second cycle only, followed by surgery and four cycles of adjuvant gemcitabine. Randomisation (1:1) was done using a minimisation technique and stratified by resectability status (resectable vs borderline resectable disease) and centre. The primary endpoint was overall survival in the modified intention-to-treat population, after excluding ineligible patients. Data on race and ethnicity were not collected. This trial is registered with EudraCT (2017-002036-17) and is complete. From June 5, 2018, to Jan 28, 2021, 375 patients were randomly assigned to the FFX group (n=188) or the CRT group (n=187). Six patients (three per group) were excluded due to ineligibility (n=4) or immediate withdrawal of informed consent after randomisation (n=2). 208 (56%) of 369 patients were male and 161 (44%) were female. After a median follow-up of 42·3 months (IQR 35·7–48·7), median overall survival was 21·9 months (95% CI 17·7–27·0) in the FFX group versus 21·3 months (16·8–25·5) in the CRT group (HR 0·88 [95% CI 0·69–1·13], p=0·32). The most common grade 3–4 adverse events were neutropenia (43 [25%] of 175 in the FFX group vs 38 [22%] of 176 in the CRT group), diarrhoea (41 [23%] vs two [1%]), and leukopenia (14 [8%] vs 26 [15%]). Serious adverse events occurred in 85 (49%) patients in the FFX group compared with 75 (43%) in the CRT group (p=0·26). Adverse events of grades 3 or worse occurred in 117 (67%) patients in the FFX group versus 106 (60%) patients in the CRT group (p=0·20). Treatment-related deaths occurred in two (1%) patients in the FFX group (multi-organ failure and intestinal mucositis) and one (1%) patient in the CRT group (upper gastrointestinal haemorrhage). This randomised trial did not show a difference in overall survival between neoadjuvant FOLFIRINOX and neoadjuvant gemcitabine-based chemoradiotherapy in patients with resectable or borderline resectable PDAC. Both neoadjuvant treatment regimens may be considered in these patients. Dutch Cancer Society and ZonMw.

PurposeRegulatory guidance suggests capturing patient-reported overall side effect impact in cancer trials. We examined whether the Functional Assessment of Cancer Therapy (FACT) GP5 item (“I am bothered by side effects of treatment”) post-neoadjuvant chemotherapy/radiotherapy differed between oxaliplatin vs. non- oxaliplatin arms in the National Surgical Adjuvant Breast and Bowel Project (NSABP) R-04 trial of stage II–III rectal cancer patients.MethodsThe R-04 neoadjuvant trial compared local-regional tumor control between patients randomized to receive 5-fluorouracil or capecitabine with radiation, with or without oxaliplatin (4 treatment arms). Participants completed surveys at baseline and immediately after chemoradiotherapy. GP5 has a 5-point response scale: “Not at all” (0), “A little bit” (1), “Somewhat” (2), “Quite a bit” (3), and “Very much” (4). Logistic regression compared the odds of reporting moderate-high side effect impact (GP5 2–4) between patients receiving oxaliplatin or not after chemoradiotherapy, controlling for relevant patient characteristics. We examined associations between GP5 and other patient-reported outcomes reflecting side effects.ResultsAnalyses were performed among 1132 study participants. Participants receiving oxaliplatin were 1.58 times (95% CI: 1.22–2.05) more likely to report moderate-high side effect bother at post-chemotherapy/radiation. In both arms, worse overall side effect impact was associated with patient-reported diarrhea, nausea, vomiting, and peripheral sensory neuropathy (p < 0.01 for all).ConclusionThis secondary analysis of R-04 found that GP5 distinguished between patients receiving oxaliplatin or not as part of their post-neoadjuvant chemoradiotherapy, adding patient-centric evidence on the reduced tolerability of oxaliplatin and demonstrating that GP5 is sensitive to known toxicity differences between treatments.ClinicalTrials.govNCT00058474.
