A Three-Part Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Single Ascending Subcutaneous Doses of HTL0030310 in Healthy Subjects

A Phase 1, first in human, three-part, single centre study to assess the safety, tolerability, PK and PD of single ascending subcutaneous doses of HTL0030310 in healthy subjects

Study Overview

• Status: Completed
• Conditions: Healthy
• Intervention / Treatment: Drug: HTL0030310; Drug: Placebo; Drug: Pasireotide

Detailed Description

This is a first in human, three part study with the objective to assess the safety, tolerability, pharmacokinetics and pharmacodynamics of single ascending subcutaneous doses of HTL0030310 in healthy subjects. Part 1 is a double-blind, placebo-controlled, randomised study assessing single ascending doses of HTL0030310. Part 2 is a site-blind (sponsor unblinded), placebo-controlled, part-randomised, fixed-sequence, single-dose, 4-period study assessing the PD of a positive control, pasireotide, following administration of challenge agents. Part 3 is a double-blind, placebo-controlled, part-randomised, fixed-sequence, single-dose, HTL0030310 proof of pharmacological effect study, where PD effects of HTL0030310 will be investigated following administration of challenge agents. The challenge agents administered in this study will be: oral glucose tolerance test (OGTT), Growth hormone-releasing hormone (GHRH), and corticotrophin releasing hormone (CRH) combined with desmopressin.

17. Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) results
18. History of clinically significant cardiovascular, renal, hepatic, chronic respiratory or GI disease, neurological or psychiatric disorder, as judged by the investigator
19. Family history of long QT syndrome or sudden cardiac death in a young adult where a cause of arrhythmia cannot be excluded
20. QTcF at screening >450 msec in males or >470 msec in females
21. Serious adverse reaction or serious hypersensitivity to any drug or the formulation excipients, including glucose/fructose intolerance for the standard OGTT
22. Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hayfever is allowed unless it is active
23. Donation or loss of greater than 400 mL of blood within the previous 3 months
24. Subjects who are taking, or have taken, any prescribed or over-the-counter drug (other than up to 4 g per day paracetamol) or herbal remedies (including St. John's Wort) in the 21 days before IMP administration (See Section 11.4 of protocol). Exceptions may apply on a case by case basis, if considered not to interfere with the objectives of the study, as agreed by the PI and sponsor's medical monitor

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Part 1 Single Ascending Dose; Eight subjects in up to 8 cohorts will be dosed. A single subcutaneous injection of HTL0030310 or placebo will be administered. In each cohort, 6 subjects will receive HTL0030310 and 2 subjects will receive placebo.	Drug: HTL0030310; Solution for Subcutaneous injection; Drug: Placebo; Matching placebo Solution
