Abstract Background:There is an urgent unmet clinical need for the identification of novel therapeutics for the treatment of COVID-19. A number of COVID-19 late phase trial platforms have been developed to investigate (often repurposed) drugs both in the UK and globally (e.g. RECOVERY led by the University of Oxford and SOLIDARITY led by WHO). There is a pressing need to investigate novel candidates within early phase trial platforms, from which promising candidates can feed into established later phase platforms. AGILE grew from a UK-wide collaboration to undertake early stage clinical evaluation of candidates for SARS-CoV-2 infection to accelerate national and global healthcare interventions. Methods/Design:AGILE is a seamless phase I/IIa platform study to establish the optimum dose, determine the activity and safety of each candidate and recommend whether it should be evaluated further. Each candidate is evaluated in its own trial, either as an open label single arm healthy volunteer study or in patients, randomising between candidate and control usually in a 2:1 allocation in favour of the candidate. Each dose is assessed sequentially for safety usually in cohorts of 6 patients. Once a phase II dose has been identified, efficacy is assessed by seamlessly expanding into a larger cohort. AGILE is completely flexible in that the core design in the master protocol can be adapted for each candidate based on prior knowledge of the candidate (i.e. population, primary endpoint and sample size can be amended). This information is detailed in each candidate specific trial protocol of the master protocol.Discussion:Few approved treatments for COVID-19 are available such as dexamethasone, remdesivir and tociluzimab in hospitalised patients. The AGILE platform aims to rapidly identify new efficacious and safe treatments to help end the current global COVID-19 pandemic. We currently have three candidate specific trials within this platform study that are open to recruitment.

Granule Formulation

Abstract Selumetinib (AZD6244, ARRY-142886) is an oral, potent and highly selective allosteric MEK 1/2 inhibitor approved by the FDA as a capsule formulation for treatment of pediatric patients ≥ 2 years old with neurofibromatosis type 1 and symptomatic, inoperable plexiform neurofibromas. A new granule formulation is being developed to support dose flexibility and for patients unable to swallow capsules. This Phase I, open-label, single-center, randomized crossover pharmacokinetics study (NCT03649165) investigated the new granule versus capsule formulation in both fasted and fed (low-fat) states. Twenty-four healthy adult male volunteers were randomized to receive single-dose selumetinib in one of four treatment sequences: 25 mg granule (fasted); 50 mg capsule (fasted); 25 mg granule (fed); and 50 mg capsule (fed). Primary endpoint: to compare pharmacokinetics of the formulations in fasted state. Secondary endpoints: pharmacokinetics of the formulations in fasted versus fed states, granule palatability, safety and tolerability. In fasted state, a slight delay in absorption of selumetinib by ~0.60 h, with geometric mean ratios (90% CI) of 0.65 (0.58, 0.74) for Cmax/dose and 0.87 (0.81, 0.92) for AUC/dose, was detected when administered as granule versus capsule. For granule in fed versus fasted states, geometric mean Cmax and AUC ratios (90% CI) were 0.61 (0.51, 0.72) and 0.97 (0.91, 1.02). For capsule in fed versus fasted states, geometric mean Cmax and AUC ratios (90% CI) were 0.40 (0.33, 0.48) and 0.62 (0.55, 0.70). Granule palatability was acceptable; volunteers indicated they would take it again. Selumetinib was well-tolerated; for both formulations, few adverse events of mild intensity were reported; dry eyes (fasted) versus dry eyes and rhinorrhea (fed) were most frequent. This was the first study to test the granule formulation in humans; results indicate the granule formulation has similar AUC to the capsule formulation and minimal food effect, supporting planned clinical trials in pediatric patients.

Recurrent Gbm

2093 Background: Recurrent glial tumors of the brain continue to be one of the most challenging malignancies to treat, and median survival for patients with recurrent disease is approximately 6 months for glioblastoma multiforme (GBM). The front-line therapy for GBM - temozolomide (TMZ) - is subject to resistance by DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT), leading to poor prognoses for patients with recurrent GBM. Dianhydrogalactitol (VAL-083)is a first-in-class bi-functional N7 DNA alkylating agent shown to cross the blood-brain barrier, accumulate in brain tissue, and have activity against GBM. Studies suggest that VAL-083 overcomes MGMT-driven drug resistance in vitro and targets cancer stem cells. The purpose of this study is to determine the maximal tolerated dose (MTD) of VAL-083 in patients with recurrent GBM or progressive secondary brain tumor, and explore the safety, pharmacokinetics and tumor responses to treatment. Methods: Open-label phase I/II dose-escalation study of VAL-083 in patients with histologically confirmed primary WHO grade 4 malignant GBM, now recurrent, previously treated for GBM with surgery and/or radiation, if appropriate, and have failed both bevacizumab and temozolomide; or progressive secondary brain tumor, has failed standard brain radiotherapy, and has brain tumor progression after at least one line of systemic therapy. The study uses a 3 + 3 dose escalation design, until reaching the MTD or maximum specified dose. Patients receive IV VAL-083 on days 1, 2, and 3 of each 21-day treatment cycle. In phase II, additional patients are treated at the MTD (or selected optimum dose) to measure tumor responses. Results: Cohort 1 (3 patients) and cohort 2 (4 patients) were completed without any DLT’s. Adverse events (AEs) have all been grade 1/2, with only 1 grade 3 AE, unrelated to treatment. Cohort 3 currently has 4 patient enrolled, without reaching the MTD. 1/7 (14.3%) patients in cohorts 1and 2 has prolonged stable disease (15+ cycles) on VAL-083 treatment. Conclusions: VAL-083 up to the 2nd dose level was well tolerated without any safety signals. Dose escalation is continuing. Clinical trial information: NCT01478178.

SummaryPurpose This study aimed to evaluate the safety and pharmacokinetic (PK) profiles of HLX07, a novel, recombinant, humanized anti-epidermal growth factor receptor (EGFR) antibody, in patients with advanced solid cancers who had failed standard therapy or for whom no standard therapy was available. Methods In this prospective, open-label, Phase I dose escalation study, patients aged ≥18 years (≥20 years for patients in Taiwan) with histologically-confirmed metastatic or recurrent epithelial carcinoma that had no K-RAS or B-RAF mutations were enrolled in a ‘3 + 3’ escalation design. HLX07 was administered weekly by 2-h intravenous infusion at doses ranging from 50 to 800 mg. The primary endpoint was summary listing of participants reporting treatment-emergent adverse events (TEAEs). Secondary endpoints included PK analysis, serum anti-HLX07 antibody assessments and efficacy. Results In total, 19 patients were enrolled between 1 October 2016 and 16 July 2019 to receive HLX07 at doses of 50 (n = 3), 100 (n = 3), 200 (n = 3), 400 (n = 3), 600 (n = 3) and 800 (n = 4) mg per week. All patients experienced at least one TEAE, most commonly fatigue (68.4%), nausea (47.4%), paronychia (31.6%) and vomiting (31.6%). Serious TEAEs were reported in 11 patients but only one serious TEAE (dyspnea in 600 mg cohort) was regarded as possibly related to study treatment. No dose limiting toxicity (DLT) was reported. Systemic exposure to HLX07 increased proportionally with dose. Anti-HLX07 antibodies were not detected in any patients. Conclusion HLX07 was well tolerated (at dose levels up to 800 mg/week) and promising in patients with advanced solid cancers.Clinical Trial Registration: The study was registered at ClinicalTrials.gov: NCT02648490 (Jan 7, 2016).
