No clinical trials with PBF-509 in humans have been performed to date. Only preclinical studies have been done to assess the pharmacology and pharmacokinetics, the safety and the toxicological profile of the PBF-509.

An initial testing of PBF-509 in humans is planned, starting with the first-into-man clinical trial where a single oral, dose-escalating, and placebo-controlled design will be implemented.

Condition Intervention Phase
Parkinson Disease Drug: PBF-509 Drug: Placebo Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Official Title: Randomized, Double Blind, Placebo Controlled "First In-human" Study To Assess the Safety and Tolerability of Single Ascending Oral Doses of PBF-509 in Male Healthy Volunteers

Primary Outcome Measures:
  • Number of Adverse Events [ Time Frame: 5-7 days post-dose ]
    Safety and Tolerability evaluation

Secondary Outcome Measures:
  • Pharmacokinetic profile analysis [ Time Frame: 0-24 h post dose ]
    pre-dose; 10; 20; 30; 40; 50; 60; 75 minutes; 1.5h; 2; 2.5; 3; 3.5; 4; 8; 12; 16; 24 hours postdose administration and after recording vital signs.

Enrollment: 56
Study Start Date: October 2012
Study Completion Date: October 2013
Primary Completion Date: October 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Placebo Comparator: Placebo
Placebo capsules: solid microcrystalline cellulose c.s.p
Drug: Placebo
Experimental: PBF-509
The initial dose-escalation scheme includes the following eight doses: 10 mg, 20 mg, 40 mg,80 mg, 160 mg, 320 mg, 480 mg and 620 mg. This dose-escalation scheme has been built with the aim to reach the Minimum Intolerated Dose (MID), i.e. when investigator should stop escalating, and consequently the MTD.
Drug: PBF-509
