Clinical Trial 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

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.

4. History of any drug or alcohol abuse in the past 2 years

5. Regular alcohol consumption in males >21 units per week and females >14 units per week (1 unit = ½ pint beer, or a 25 mL shot of 40% spirit, 1.5 to 2 Units = 125 mL glass of wine, depending on type)

6. Current smokers and those who have smoked within the last 12 months. A breath carbon monoxide reading of greater than 10 ppm at screening and admission

7. Current users of e-cigarettes and nicotine replacement products and those who have used these products within the last 12 months

8. Females of childbearing potential. A woman is considered of childbearing potential unless she is permanently sterile (hysterectomy, bilateral salpingectomy and bilateral oophorectomy) or is postmenopausal (had no menses for 12 months without an alternative medical cause and a serum FSH concentration =40 IU/L). All female subjects must have a negative urine pregnancy test

9. Subjects who do not have suitable veins for multiple venepunctures/cannulation as assessed by the investigator at screening

10. Subjects with vital signs outside the normal range for healthy volunteers (HR < 50 or >90 bpm; Systolic BP > 140 mmHg; Diastolic BP > 90 mmHg)

11. Clinically significant abnormal biochemistry, haematology, coagulation or urinalysis as judged by the investigator (laboratory parameters are listed in Appendix 1 of the protocol)

12. Fasting blood glucose at screening above the upper limit of normal (3.9 to 5.8 mM)

13. HbA1c at screening above the upper limit of normal (>6%)

14. Abnormal renal function - defined as creatinine clearance < 70mL/min using the Cockcroft-Gault equation at screening

15. Abnormal hepatic function - defined as ALT, AST and total bilirubin > 1.5 x upper limit of normal at screening

16. Positive drugs of abuse test result (drugs of abuse tests are listed in Appendix 1 of the protocol)

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

25. Subjects with tattoos or scars on the abdomen which may interfere with injection site assessments or pharmacodynamic measurements, as determined by the PI or delegate at screening

26. Failure to satisfy the investigator of fitness to participate for any other reason Exclusion criteria 11, 16, 22, 24 and 26 from the list above will be re-assessed at admission/pre-dose.
