Overview
Brief Summary
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
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.

Arms & Interventions
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.
Intervention: HTL0030310
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.
Intervention: Placebo
Part 2 Pasireotide PD Assessment
Sixteen subjects in 2 cohorts (8 subjects per cohort) will be dosed on 4 occasions. Within each cohort, 4 subjects will be randomised to active dosing with CRH with desmopressin, GHRH and OGTT challenge and 4 subjects will be randomised to placebo dosing with CRH with desmopressin, GHRH and OGTT challenge.
Intervention: Pasireotide
Part 2 Pasireotide PD Assessment
Sixteen subjects in 2 cohorts (8 subjects per cohort) will be dosed on 4 occasions. Within each cohort, 4 subjects will be randomised to active dosing with CRH with desmopressin, GHRH and OGTT challenge and 4 subjects will be randomised to placebo dosing with CRH with desmopressin, GHRH and OGTT challenge.
Intervention: Placebo
Part 3 Proof of Pharmacological Effect
Up to 80 subjects in 4 cohorts (up to 20 subjects per cohort) will be dosed in up to 3 study periods. In each period, subjects will receive active drug or placebo with GHRH, OGTT and CRH with desmopressin (optional).
Intervention: HTL0030310
Part 3 Proof of Pharmacological Effect
Up to 80 subjects in 4 cohorts (up to 20 subjects per cohort) will be dosed in up to 3 study periods. In each period, subjects will receive active drug or placebo with GHRH, OGTT and CRH with desmopressin (optional).
Intervention: Placebo
