Background: Prior durvalumab (anti-PD-L1 agent) studies in platinum-refractory metastatic urothelial carcinoma evaluated a dose of 10 mg/kg administered every two weeks. The nonrandomised phase 3b STRONG study (NCT03084471) evaluated the safety and efficacy of fixed-dose durvalumab at a more convenient dosing schedule in a previously treated patient population, more similar to a real-world clinical setting.
Patients And Methods: 867 patients with urothelial or nonurothelial urinary tract carcinoma (UTC) who progressed on or after platinum or nonplatinum chemotherapy were treated with durvalumab 1500 mg every four weeks; 87% had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1, and 13% had an ECOG PS of 2. The primary end-point was the incidence of adverse events of special interest (AESIs), including immune-mediated AEs (imAEs). Secondary and exploratory end-points included overall survival (OS), objective response rate (ORR) and disease control rate (at six and 12 months) (DCR).
Results: AESIs of any grade were reported in 51% of patients (8% grade ≥ 3). The incidence of imAEs was 11% (2% grade ≥ 3). The median OS was 7.0 months (95% confidence interval [CI]: 6.4-8.2) and ORR was 18% (95% CI: 14.8-20.6), with complete responses in 5% of patients and a DCR at six months of 19% (95% CI: 16.1-22.1).
Conclusion: Fixed-dose durvalumab monotherapy every four weeks has an acceptable safety profile and yields durable clinical activity in previously chemotherapy-treated patients with UTC. Safety and efficacy are consistent with previous durvalumab studies and other anti-PD-1/PD-L1 agents in this setting. CLINICALTRIALS.

Objective: To analyse the economic impact of the use of immune checkpoint inhibitors in fixed-dose regimens and to determine the potential economic savings of using weight-adjusted dosing, as well as to describe the current situation in Spanish hospitals.
Methods: Observational, descriptive, retrospective and multicentre study that included all patients treated with pembrolizumab, nivolumab, avelumab, durvalumab and cemiplimab in fixed-dose regimens from 2020 to 2022 in four hospitals in a Spanish province (Albacete). Clinical variables: drug, therapeutic indication, body weight, percentage of overdose and number of cycles received.

Purpose: Concurrent chemoradiation therapy is the current nonsurgical standard of care for locally advanced non-small cell lung cancer. However, this is a difficult regimen to tolerate, especially for those who are elderly, have multiple comorbidities, or have poor performance status. Alternative treatment regimens are needed for this vulnerable population.

Background: The primary objective of this phase I, open-label trial was to assess safety and tolerability of tremelimumab monotherapy and combination therapy with durvalumab in Japanese patients with advanced cancer. Tremelimumab is a fully human monoclonal antibody against CTLA-4 in clinical trials; durvalumab is a monoclonal antibody against PD-L1 for the treatment of bladder and lung cancer.
Methods: In part 1, tremelimumab 3 or 10 mg/kg was given every 4 weeks (Q4W) for 6 doses, and thereafter every 12 weeks until discontinuation (n = 8); subsequently tremelimumab 10 mg/kg Q4W for 6 doses/Q12W and thereafter until discontinuation was administered in 41 patients with malignant pleural or peritoneal mesothelioma (MPM).

Background And Purpose: To report on the anti-tumor activity of a novel combination in high-risk locally advanced head and neck squamous cell carcinoma.
Materials And Methods: At a fixed dose of 1500 mg every 28 days, anti PD-L1 Durvalumab was given concomitantly to Radiotherapy and Cetuximab starting from the first week of combined treatment, followed by adjuvant Durvalumab to a maximum of 6 months after completion of radiation. The primary endpoint of the study was 2-year progression-free survival (PFS).
