Open-label, randomized multicentre phase II study to assess the efficacy and tolerability of sunitinib by dose administration regimen (dose modification or dose interruptions) in patients with advanced or metastatic renal cell carcinoma: study protocol of the SURF trial.

ABSTRACT: BACKGROUND:Sunitinib is a tyrosine kinase inhibitor approved in the first-line metastatic renal cell carcinoma (MRCC) setting at the dose of 50 mg daily for 4 weeks followed by a pause of 2 weeks. Due to toxicity, this standard schedule (50 mg daily 4/2) can induce up to 50% of sunitinib dose modification (reduction and/or interruption). The current recommendation in such case is to reduce the dose to 37.5 mg per day (standard schedule 4/2). Recent data highlight an alternative schedule: 2 weeks of treatment followed by 1 week of pause (experimental schedule 2/1). The SURF trial is set up to evaluate prospectively experimental schedule 2/1 when toxicity occurs. This article displays the key elements of the study protocol. METHODS/DESIGN:SURF [NCT02689167] is a prospective, randomized, open-label phase IIb study. Patients are included at sunitinib initiation while receiving standard schedule 4/2 (50 mg daily) according to the marketing authorization indication. When a dose adjustment of sunitinib is required, patients are randomized between standard schedule 4/2 (37.5 mg daily) and experimental schedule 2/1 (50 mg daily). Key eligibility criteria are the following: patients with locally advanced inoperable or MRCC who are starting first-line treatment with sunitinib, with histologically or cytologically confirmed renal cancer clear cell variant or with a clear cell component, and with Karnofsky performance status ?70%. The primary objective is to assess the median duration of sunitinib treatment (DOT) in each group. The key secondary objectives are progression-free survival, overall survival, time to randomization, objective response rate, safety, sunitinib dose intensity, health-related quality of life, and the description of main drivers triggering randomization. We hypothesized that experimental schedule 2/1 would result in an improvement in median DOT from 6 to 8.5 months. It was estimated that 112 patients would be needed in each arm during 24 months. In order to take into account the possibility of treatment discontinuation before randomization, 248 patients are necessary. DISCUSSION:The SURF trial is asking a pragmatic question adapted to the current practice on what is the best way to adapt sunitinib when treatment-related adverse events occur. The results of the SURF trial will bring high-value data to support the use of an alternative schedule in sunitinib treatment. TRIAL REGISTRATION:ClinicalTrials.gov, NCT02689167 .

Project description:The contraceptive efficacy and tolerability of a new flexible extended regimen of ethinylestradiol (EE) 20 ?g/drospirenone (DRSP) 3 mg to extend the menstrual cycle and enable management of intracyclic (breakthrough) bleeding (flexible(MIB)) was investigated and the bleeding pattern compared with a conventional 28-day regimen and a fixed extended 124-day regimen.This Phase III, 2-year, multicentre, open-label study randomly (4:1:1) allocated women (aged 18-35 years) to the following regimens: flexible(MIB) (24-120 days' active hormonal intake with 4-day tablet-free intervals); conventional (24 days' active hormonal intake followed by a 4-day hormone-free interval); or fixed extended (120 days' uninterrupted active hormonal intake followed by a 4-day tablet-free interval). Primary outcomes included the number of bleeding/spotting days during Year 1 (all regimens) and the number of observed unintended pregnancies over 2 years (flexible(MIB) only).Results were analysed in 1067 women (full analysis set). The mean number of bleeding/spotting days was lower with the flexible(MIB) vs the conventional regimen [41.0±29.1 (95% CI 38.8-43.3) vs 65.8±27.0 (95% CI 62.2-69.4) days, p<0.0001; treatment difference -24.8 (95% CI -29.2 to -20.3) days]. The corresponding value for the fixed extended regimen was 60.9±51.1 (95% CI 53.9-67.9) days. The Pearl Index for the flexible(MIB) regimen was 0.64 (95% CI 0.28-1.26). All regimens had comparable tolerability profiles.EE 20 ?g/DRSP 3 mg administered as a flexible extended regimen with MIB is effective, well tolerated and is associated with statistically significantly fewer bleeding/spotting days and fewer withdrawal bleeding episodes vs EE/DRSP in a conventional 28-day regimen. The flexible(MIB) also provided statistically significantly fewer spotting days vs EE/DRSP in a fixed extended 124-day regimen (post hoc evaluation). The flexible(MIB) regimen allows women to extend their menstrual cycle and manage their intracyclic (breakthrough) bleeding.

Project description:Summary Background Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease caused by the loss of motor neurons, and development of effective medicines is urgently required. Induced pluripotent stem cell (iPSC)-based drug repurposing identified the Src/c-Abl inhibitor bosutinib, which is approved for the treatment of chronic myelogenous leukemia (CML), as a candidate for the molecular targeted therapy of ALS. Methods An open-label, multicentre, dose-escalation phase 1 study using a 3 + 3 design was conducted in 4 hospitals in Japan to evaluate the safety and tolerability of bosutinib in patients with ALS. Furthermore, the exploratory efficacy was evaluated using Revised ALS Functional Rating Scale (ALSFRS-R), predictive biomarkers including plasma neurofilament light chain (NFL) were explored, and single-cell RNA sequencing of iPSC-derived motor neurons was conducted. Patients, whose total ALSFRS-R scores decreased by 1–3 points during the 12-week, received escalating doses starting from 100 mg quaque die (QD) up to 400 mg QD based on dose-limiting toxicity (DLT) occurrence, and all participants who received one dose of the study drug were included in the primary analysis. This trial is registered with ClinicalTrials.gov, NCT04744532, as Induced pluripotent stem cell-based Drug Repurposing for Amyotrophic Lateral Sclerosis Medicine (iDReAM) study. Findings Between March 29, 2019 and May 7, 2021, 20 patients were enrolled, 13 of whom received bosutinib treatment and 12 were included in the safety and efficacy analyses. No DLTs were observed up to 300 mg QD, but DLTs were observed in 3/3 patients of the 400 mg QD cohort. In all patients receiving 100 mg–400 mg, the prevalent adverse events (AEs) were gastrointestinal AEs in 12 patients (92.3%), liver function related AEs in 7 patients (53.8%), and rash in 3 patients (23.1%). The safety profile was consistent with that known for CML treatment, and ALS-specific AEs were not observed. A subset of patients (5/9 patients) was found to respond well to bosutinib treatment over the 12-week treatment period. It was found that the treatment-responsive patients could be distinguished by their lower levels of plasma NFL. Furthermore, single-cell RNA sequencing of iPSC-derived motor neurons revealed the pathogenesis related molecular signature in patients with ALS showing responsiveness to bosutinib. Interpretation This is the first trial of a Src/c-Abl inhibitor, bosutinib, for patients with ALS. The safety and tolerability of bosutinib up to 300 mg, not 400 mg, in ALS were described, and responsiveness of patients on motor function was observed. Since this was an open-label trial within a short period with a limited number of patients, further clinical trials will be required. Funding AMED and iPS Cell Research Fund.

Project description:BACKGROUND:The current maintenance dose (10,000 AUeq/monthly) of a subcutaneous allergoid for house dust mite (HDM) immunotherapy has previously shown significant clinical efficacy in patients with HDM induced allergic rhinitis or rhinoconjunctivitis. In order to comply with the 2009 EMA guidelines on immunotherapy products, a study was conducted to evaluate the safety, tolerability and short-term treatment effects of up-dosing regimens with high doses (up to 40,000 AUeq) of allergoid HDM immunotherapy. METHODS:In total 48 patients with HDM-allergic rhinitis or rhinoconjunctivitis (29 M/19 F; 18-53 years) were included and enrolled into one of three up-dosing regimens (1:4:4): 1) a regular regimen with up-dosing to 40,000 AUeq followed by two maintenance doses (total duration 17 weeks), 2) an intermediate regimen (14 weeks) or 3) a fast regimen (11 weeks). Safety and tolerability were evaluated by monitoring of early and late local reactions and systemic reactions. In addition, short-term effects were assessed by conjunctival provocation test (CPT) and levels of serum allergen-specific IgE, IgG and IgG4. RESULTS:Thirty-nine patients completed the study according to protocol. No early local reactions occurred. Late local reactions (LLR) were observed in 12% of the injections. In total, 31 systemic reactions, all grade 1, were reported of which two needed oral antihistamine treatment. No grade 2 or higher systemic reactions were observed. Six patients (15%) did not reach the highest dose due to LLR and/or systemic reactions needing antihistamines (20% in the regular regimen, 16% in the intermediate regimen and 13% in the fast regimen). At the end of the study, an improvement in the CPT was observed in 82.1% of patients, indirectly indicating an early treatment effect at the current dose and higher doses. In addition, IgG4 immunoglobulin levels were significantly increased in all groups following treatment. CONCLUSIONS:In this open-label study, allergoid HDM immunotherapy in doses up to 40,000 AUeq was generally well tolerated and no clinically relevant safety issues were identified. In the safety aspects of the three up-dosing regimens no clinically relevant differences were encountered. Therefore, these dose ranges and up-dosing regimens can be safely included in future dose-finding efficacy studies.

Project description:BackgroundNovel approaches are required to improve outcomes in relapsed or refractory classical Hodgkin lymphoma and non-Hodgkin lymphoma. We aimed to evaluate camidanlumab tesirine, an anti-CD25 antibody-drug conjugate, in this patient population.MethodsThis was a phase 1, dose-escalation (part 1), dose-expansion (part 2), multicentre trial done in 12 hospital sites (seven in the USA and five in the UK). Adults (≥18 years old) with pathologically confirmed relapsed or refractory classical Hodgkin lymphoma or non-Hodgkin lymphoma, an Eastern Cooperative Oncology Group performance status 0-2, who had no therapies available to them with established clinical benefit for their disease stage were enrolled. Camidanlumab tesirine was administered intravenously (3-150 μg/kg) once every 3 weeks. Primary objectives were to assess dose-limiting toxicity, determine maximum tolerated dose and recommended expansion dose(s), and assess safety of camidanlumab tesirine. Safety was assessed in all treated patients; antitumour activity was assessed in patients with one or more valid baseline and post-baseline disease assessment and in those who had disease progression or died after first study-drug dose. This trial was registered with ClinicalTrials.gov, NCT02432235.FindingsBetween Oct 5, 2015, and Jun 30, 2019, 133 patients were enrolled (77 [58%] had classical Hodgkin lymphoma and 56 (42%) had non-Hodgkin lymphoma). Median follow-up was 9·2 months (IQR 4·2-14·3). Eight dose-limiting toxicities were reported in five (6%) of 86 patients who were evaluable; the maximum tolerated dose was not reached. The recommended doses for expansion were 30 μg/kg and 45 μg/kg for patients with classical Hodgkin lymphoma and 80 μg/kg for patients with T-cell non-Hodgkin lymphomas. No recommended doses for expansion were defined for B-cell non-Hodgkin lymphomas. Grade 3 or worse treatment-emergent adverse events (reported by ≥10% of the 133 patients) included increased γ-glutamyltransferase (20 [15%] patients), maculopapular rash (16 [12%]), and anaemia (15 [11%]); 74 (56%) patients had serious treatment-emergent adverse events, most commonly pyrexia (16 [12%]). One (1%) fatal treatment-emergent adverse event and two (2%) deaths outside the reporting period were considered at least possibly study-drug related. Antitumoural activity was seen in classical Hodgkin and non-Hodgkin lymphomas; notably in all patients with classical Hodgkin lymphoma, the overall response was 71% (95% CI 60-81).InterpretationThese results warrant evaluation of camidanlumab tesirine as a potential treatment option for relapsed or refractory lymphoma, particularly in patients with classical Hodgkin lymphoma.FundingADC Therapeutics.
