BackgroundGalunisertib is the first-in-class, first-in-human, oral small-molecule type I transforming growth factor-beta receptor (ALK5) serine/threonine kinase inhibitor to enter clinical development. The effect of galunisertib vs. placebo in patients with unresectable pancreatic cancer was determined.MethodsThis was a two-part, multinational study: phase 1b was a non-randomised, open-label, multicentre, and dose-escalation study; phase 2 was a randomised, placebo- and Bayesian-augmented controlled, double-blind study in patients with locally advanced or metastatic pancreatic adenocarcinoma considered candidates for first-line chemotherapy with gemcitabine. Patients were randomised 2:1 to galunisertib–gemcitabine (N = 104) or placebo-gemcitabine (N = 52). Gemcitabine dose was 1000 mg/m2 QW. Primary endpoints for phases 1b and 2, respectively, were phase 2 dose and overall survival. Secondary objectives included tolerability and biomarkers.ResultsDose-escalation suggested a 300-mg/day dose. Primary objective was met: median survival times were 8.9 and 7.1 months for galunisertib and placebo, respectively (hazard ratio [HR] = 0.79 [95% credible interval: 0.59–1.09] and posterior probability HR < 1 = 0.93). Lower baseline biomarkers macrophage inflammatory protein-1-alpha and interferon-gamma-induced protein 10 were associated with galunisertib benefit.ConclusionsGalunisertib–gemcitabine combination improved overall survival vs. gemcitabine in patients with unresectable pancreatic cancer, with minimal added toxicity. Future exploration of galunisertib in pancreatic cancer is ongoing in combination with durvalumab.

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.

Preventing HIV-1 infection is a high global priority. This study assessed prevention strategies in young women in South Africa, Uganda, and Zimbabwe using oral or vaginal antiretroviral agents. No approach was found to be effective. The HIV-1 incidence was 5.7 per 100 person-years. Daily oral preexposure prophylaxis with 300 mg of tenofovir disoproxil fumarate (TDF), alone or in combination with 200 mg of emtricitabine (FTC) (TDF-FTC [Truvada, Gilead Sciences]), reduces the risk of acquisition of human immunodeficiency virus type 1 (HIV-1) by 50% or more among persons with high adherence to the regimen, with demonstrated efficacy in men who have sex with men, heterosexuals, and injection-drug users. 1 – 4 On the basis of these observations, in July 2012 the Food and Drug Administration approved daily treatment with Truvada for the prevention of HIV-1 acquisition, and the Centers for Disease Control and Prevention has issued . . .

Adding three cycles of induction chemotherapy with gemcitabine and cisplatin to concurrent chemoradiotherapy improved 3-year recurrence-free survival (85.3%, vs. 76.5% with concurrent chemoradiotherapy alone) and overall survival (94.6% vs. 90.3%). Patients receiving induction chemotherapy were more likely to have grade 3 or 4 myelosuppression, nausea, and vomiting.

In this study, 2499 HIV-seronegative men or transgender women who were at high risk for HIV acquisition were enrolled in a trial of daily emtricitabine plus tenofovir versus placebo. Those receiving the antiretroviral medication had a 44% reduction in HIV incidence. A total of 2.7 million new infections with the human immunodeficiency virus (HIV) were diagnosed worldwide in 2008, according to the Joint United Nations Program on HIV/AIDS (UNAIDS). Combination antiretroviral therapy for patients with HIV infection restores health and may decrease the transmission of the virus to uninfected partners. 1 Therapy also decreases mother-to-child transmission. 2 Postexposure chemoprophylaxis is recommended after occupational or nonoccupational exposure to HIV-infected fluids. 3 The use of such chemoprophylaxis requires that people recognize when they might have been exposed to HIV and that they start therapy within 72 hours. Both challenges are substantial limitations to the use of . . .

In a prospective, randomized trial involving patients with resected pancreatic cancer, adjuvant combination chemotherapy with FOLFIRINOX resulted in a median disease-free survival of 21.6 months, as compared with 12.8 months with gemcitabine therapy. Overall survival was also longer with FOLFIRINOX.

Neoadjuvant chemotherapy followed by radical cystectomy is the standard treatment for cisplatin-eligible patients with muscle-invasive bladder cancer. Adding perioperative immunotherapy may improve outcomes. In this phase 3, open-label, randomized trial, we assigned, in a 1:1 ratio, cisplatin-eligible patients with muscle-invasive bladder cancer to receive neoadjuvant durvalumab plus gemcitabine-cisplatin every 3 weeks for four cycles, followed by radical cystectomy and adjuvant durvalumab every 4 weeks for eight cycles (durvalumab group), or to receive neoadjuvant gemcitabine-cisplatin followed by radical cystectomy alone (comparison group). Event-free survival was one of two primary end points. Overall survival was the key secondary end point. In total, 533 patients were assigned to the durvalumab group and 530 to the comparison group. The estimated event-free survival at 24 months was 67.8% (95% confidence interval [CI], 63.6 to 71.7) in the durvalumab group and 59.8% (95% CI, 55.4 to 64.0) in the comparison group (hazard ratio for progression, recurrence, not undergoing radical cystectomy, or death from any cause, 0.68; 95% CI, 0.56 to 0.82; P<0.001 by stratified log-rank test). The estimated overall survival at 24 months was 82.2% (95% CI, 78.7 to 85.2) in the durvalumab group and 75.2% (95% CI, 71.3 to 78.8) in the comparison group (hazard ratio for death, 0.75; 95% CI, 0.59 to 0.93; P = 0.01 by stratified log-rank test). Treatment-related adverse events of grade 3 or 4 in severity occurred in 40.6% of the patients in the durvalumab group and in 40.9% of those in the comparison group; treatment-related adverse events leading to death occurred in 0.6% in each group. Radical cystectomy was performed in 88.0% of the patients in the durvalumab group and in 83.2% of those in the comparison group. Perioperative durvalumab plus neoadjuvant chemotherapy led to significant improvements in event-free survival and overall survival as compared with neoadjuvant chemotherapy alone.

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.

There are limited treatment options for infection with the respiratory syncytial virus. In this human challenge model, a new oral nucleoside analogue, ALS-008176, showed modest antiviral activity. Respiratory syncytial virus (RSV) infections are a cause of substantial morbidity and mortality in various patient populations worldwide, including children. Globally, RSV infections were estimated to cause 3.4 million hospitalizations and 66,000 to 199,000 deaths in 2005 in children younger than 5 years of age, primarily in the developing world. 1 In U.S. infants, RSV infection causes substantial outpatient disease 2 and is a common cause of hospitalization. 3 The risk of death from respiratory causes is nine times as high among U.S. infants with RSV infection as the risk among infants with influenza. 4 Immunocompromised patients and elderly patients, especially those with coexisting . . .

Gemcitabine-cisplatin (GP) chemotherapy is the standard first-line systemic treatment for recurrent or metastatic nasopharyngeal carcinoma (RM-NPC). In this international, double-blind, phase 3 trial (ClinicalTrials.gov identifier: NCT03581786), 289 patients with RM-NPC and no previous chemotherapy for recurrent or metastatic disease were randomized (1/1) to receive either toripalimab, a monoclonal antibody against human programmed death-1 (PD-1), or placebo in combination with GP every 3 weeks for up to six cycles, followed by monotherapy with toripalimab or placebo. The primary endpoint was progression-free survival (PFS) as assessed by a blinded independent review committee according to RECIST v.1.1. At the prespecified interim PFS analysis, a significant improvement in PFS was detected in the toripalimab arm compared to the placebo arm: median PFS of 11.7 versus 8.0 months, hazard ratio (HR) = 0.52 (95% confidence interval (CI): 0.36–0.74), P  = 0.0003. An improvement in PFS was observed across key subgroups, including PD-L1 expression. As of 18 February 2021, a 40% reduction in risk of death was observed in the toripalimab arm compared to the placebo arm (HR = 0.603 (95% CI: 0.364–0.997)). The incidence of grade ≥3 adverse events (AEs) (89.0 versus 89.5%), AEs leading to discontinuation of toripalimab/placebo (7.5 versus 4.9%) and fatal AEs (2.7 versus 2.8%) was similar between the two arms; however, immune-related AEs (irAEs) (39.7 versus 18.9%) and grade ≥3 irAEs (7.5 versus 0.7%) were more frequent in the toripalimab arm. In conclusion, the addition of toripalimab to GP chemotherapy as a first-line treatment for patients with RM-NPC provided superior PFS compared to GP alone, and with a manageable safety profile. Interim analysis from the randomized phase 3 JUPITER-02 trial shows that the addition of anti-PD-1 toripalimab to standard gemcitabine/cisplatin as a first-line treatment for patients with recurrent or metastatic nasopharyngeal carcinoma has manageable toxicity and improves progression-free survival, suggesting a potential new treatment standard in this setting.
