Clinical Trial Summary

Primary objective:

To assess the potential effect of oral Clarithromycin on the single-dose pharmacokinetics of Givinostat.

Secondary objective:

To assess the safety and tolerability of concomitant administration of Givinostat plus Clarithromycin.

Description:

This study was planned as a phase I, open-label, 3-part, fixed-sequence, non-randomized study in healthy male and female subjects. The study (Part 2) aimed at assessing the potential effect of Clarythromycin on the single dose pharmacokynetics of Givinostat.

The total duration of Part 2 was divided as follows:

• Screening: up to 21 days.

• Treatment Period: Days 1 to 11.

• Safety follow-up visit: 12±2 days.

Subjects were confined at site from Day -1 to Day 11. On Days 1 and 8, a single dose of 50 mg Givinostat, as oral suspension, was administered 1 hour after the planned morning time of Clarithromycin administration.

From Day 4 to Day 10, clarithromycin 500 mg film-coated tablets were administered twice a day, in the morning and in the evening.

The following assessments were performed:

• Blood collection for pharmacokinetic analysis on Days 1 to 4 and 8 to 11.

• Vital signs measurements on Days 1 and 4 to 10.

• 12-lead ECG on Days 1, 3, 7 and 8.

• Blood collection for laboratory tests (hematology and biochemistry) on Day 3.

Subjects were discharged in the morning of Day 11 after completing end of study procedures.

Secondary	Severity of Treatment Emergent Adverse Events (TEAE)	An AE was considered as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily imply a causal relationship with this treatment. An AE can, therefore, be any unfavorable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. The period of observation for the collection of medical occurrences extended from the time when the subject gave Informed Consent until the follow-up visit.	Throughout the study and 10-14 days after the EoS (follow-up visit), i.e. up to day 30-34
