PDM08

Jorge Barriuso, MD, PhD

This phase I study in adult patients with advanced solid tumours is designed to evaluate toxicity, drug exposure (pharmacokinetics) and drug action (pharmacodynamics) of a new molecule, PDM08, administered twice a week cycles of 4 weeks. This drug has shown antitumoral activity in several murine cancer models.

Phase I study, open, dose escalation, in adult patients with advanced solid tumours, to evaluate tolerability, pharmacokinetics and pharmacodynamics of ascending PDM08 doses administered twice a week cycles of 4 weeks.

After checking the safety of the first drug doses, a new dose escalation was proposed and approved by the Ethic Committee and the Medicines Agency.

This clinical trial is carried out in adult patients with advanced solid tumours whose disease has progressed despite standard therapy, or for which there is no standard antineoplastic therapy, or are refractory to it.

In pharmacodynamic non clinical studies, PDM08 presented antitumour activity against different tumour models including, renal, colon, lung, prostate and breast cancer models.

PDM08 Clinical Trial in Advanced Solid Tumors

Phase I Study, Open, Dose Escalation, in Adult Patients With Advanced Solid Tumours, to Evaluate Tolerability, Pharmacokinetics and Pharmacodynamics of PDM08 Administered Twice a Week Cycles of 4 Weeks.

Drug safety will be measured by the number and grade of adverse events, by participant, related to the drug in study (PDM08) in the cohorts studied: 560 μg, 1.12 mg, 2.24 mg, 3.5 mg and 14 mg, 28 mg and 56 mg administered twice a week for four weeks.

The drug will be administered twice a week for four weeks.

Safety and tolerability will be measured considering the adverse events occurred, by participant, related with the drug in study, PDM08, at each cohort.

Drug tolerability will be assessed by determining the DLT. It will be determined for each cohort (increasing multiple doses of PDM08): 560 μg, 1.12 mg, 2.24 mg, 3.5 mg and 14 mg, 28 mg and 56 mg administered twice a week for four weeks). Dose Limiting Toxicity will be considered the dose that produces adverse events of a severity grade 3 or greater, related to the drug in study (PDM08) in the classification specified in the list of Toxicity Criteria of the National Cancer Institute (CTCAE v04.03).

Blood sampling collected on Day 1 and 25 of each cohort cycle.Cohorts (doses): 560 μg, 1.12 mg, 2.24 mg, 3.5 mg and 14 mg, 28 mg and 56 mg administered twice a week for four weeks.

Blood collection scheme: - Dose of 560 μg and 1.12 mg: 0,0.25, 1, 2, 4, 8, 12 hours post-dose, on day 1 and day 25 of each cycle. - Doses of 2.24 mg, 3.5 mg, 14 mg, 28 mg, and 56 mg: 0,0.25, 1, 2, 4, 8, 12, 16 and 24 hours post-dose, on day 1 and day 25 of each cycle.

Pharmacokinetic parameters will be expressed as mean ± standard deviation and confidence interval 95%. Linearity will be analyzed.
