A phase I trial to determine safety and pharmacokinetics of ASLAN002, an oral MET superfamily kinase inhibitor, in patients with advanced or metastatic solid cancers.

Background The MET tyrosine kinase and its ligand, hepatocyte growth factor (HGF) also known as scatter factor, are associated with tumourigenesis and metastasis by promotion of scattering, proliferation, angiogenesis, motility and invasion. ASLAN-002 is a potent inhibitor of MET as well as related kinases. A phase I dose escalation study was conducted to determine the safety and pharmacokinetics of ASLAN-002 in patients with advanced cancer. Methods Patients with advanced or metastatic solid tumours, who had progressed on standard therapy or for whom standard therapy was not known, were administered ASLAN-002 orally. The starting dose was 100 mg once daily (QD) with subsequent cohorts to receive doses of 200 mg QD, 300 mg QD, 450 mg QD, 600 mg QD, 300 mg twice daily (BID), 450 mg BID, and 600 mg BID. Results Forty patients were included across 7 dose cohorts. Cohort 8 (600 mg BID) was not opened due to the lack of appreciable pharmacokinetic (PK) differences between 300 mg BID and 450 mg BID and higher incidences of grade 3 or 4 adverse events (AE) in Cohort 7 (450 mg BID). Fifteen patients (37.5%) experienced a grade 3 or 4 AE. The most commonly reported AEs were nausea (55%), fatigue (47.5%) and constipation (30%). One dose limiting toxicity (DLT) of atrial fibrillation was observed with 450 mg BID. Conclusions ASLAN-002 is well tolerated at 300 mg BID and is the recommended dose for future phase II studies (RP2D). Clinical Trials Registry Number: NCT01721148 .

Tricaprilin (CER-0001) for the preventive treatment of migraine: A phase 2 randomised, double-blind, placebo-controlled pilot study.

BACKGROUND: Increasing evidence indicates a metabolic etiology for migraines, with ketosis potentially rectifying metabolic and clinical features. We conducted a pilot study to evaluate CER-0001, a ketogenic agent, for migraine prevention without dietary changes. METHODS: This was a 2-part, double-blind, randomised, placebo-controlled study conducted in Australia. Adults with at least a 1-year history of migraine and ≥ 1 prior preventive treatment failure were randomised to either oral CER-0001 (up to 30 g twice a day) or placebo for 12 weeks. The primary endpoint was Month 3 change in Migraine Headache Days from baseline. RESULTS: Part 1 results are presented. 81 participants were randomised and dosed (n = 40 CER-0001, n = 41 placebo), and 61 participants had evaluable efficacy data. No statistically significant difference was observed in the primary endpoint (LSMean difference 0.92 days; p = 0.586). During Month 2, a mean improvement of -2.8 days was observed for CER-0001 (p = 0.056). Withdrawal rates were 45.0% and 53.7% (CER-0001; placebo). The proportion of participants reporting at least one treatment-emergent adverse event was similar between arms (90.0% CER-0001, 82.9% placebo), mostly gastrointestinal (85.0% CER-0001, 70.7% placebo). CONCLUSION: Results suggest positive directional promise over 2-3 months for CER-0001. A new formulation will be used for larger, fully powered phase 2/3 studies. TRIAL REGISTRATION: This study is registered at ClinicalTrials.gov (NCT04437199).
