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.

| Primary | Number and grade of adverse events by participant related to PDM08. | 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. |
6 weeks for each cohort. | Yes |
| Primary | Dose limiting toxicity (DLT) | 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). | 6 weeks. | Yes |
| Secondary | AUC | 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. |
