Clinical Trial Summary

This study will evaluate how the test medicine DNDI-0690 is taken up and broken down by the body and will also look at the safety and tolerability of the test medicine after a single dose. This is the first time the test medicine DNDI-0690 will be administered to humans.

Description:

DNDI-0690 is intended to be used as oral treatment for Visceral Leishmaniasis with potential for the cutaneous form of the disease, Cutaneous Leishmaniasis. The present protocol describes the first-in-human (FIH) study with DNDI-0690.

Subjects with Gilbert's syndrome are allowed

• Confirmed positive drugs of abuse test result

• Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results

• History of additional risk factors for Torsades des Pointe (eg heart failure, hypokalaemia, family history of long QT syndrome)

• Rare hereditary problems of fructose intolerance, glucose-galactose malabsorption or sucrose-isomaltase insufficiency

• Any relevant GI complaints within 7 days of dosing

• Subjects with a history of cholecystectomy or gall stones (Cohort 7 only)

• Serious adverse reaction or clinically relevant hypersensitivity to any drug or the formulation excipients (Hypromellose [HPMC], sodium lauryl sulphate [SLS], sucrose, croscarmellose sodium and magnesium stearate)

• Presence or history of clinically significant allergy requiring treatment (including asthma, urticaria, clinically significant allergic rash or other severe allergic diathesis), as judged by the investigator. Hay fever is allowed unless it is active

• Donation or loss of greater than 500 mL of blood within the previous 3 months or more than 100 mL within 30 days before signing Informed Consent Form (ICF) to this trial

• Subjects who are taking, or have taken, any prescribed or over-the-counter drug (including anti-acid drugs) or vitamins/herbal remedies (eg St. John's Wort and others which are known to interfere with the Cytochrome P450 3A4 (CYP3A4) and P-glycoprotein (P-gp) metabolic pathways) or HRT in the 21 days before IMP administration. Administration of up to 4 g of paracetamol per day within 7 days of IMP administration is allowed

• Surgery within 12 weeks prior to screening, with the exception of appendectomy
