About

This is a two-part, single centre, double-blind (within cohorts), randomised, placebo-controlled, single (Part 1) and multiple (Part 2) ascending subcutaneous dose study in lean to overweight or obese but otherwise healthy men (Part 1) and men and non-pregnant, non-lactating women (Part 2). The primary objective is to assess the safety and tolerability. Secondary objectives are to characterize the pharmacokinetics (PK) and to investigate pharmacodynamic effects.

Full description

This is a phase 1 clinical trial of a new long-acting amylin analogue GUB014295 in two parts.

Trial design: Part 1 is a double-blind (within cohorts), randomised, placebo-controlled, single ascending dose (SAD) study. It is planned to enrol 4 cohorts of 8 subjects (Regimens A, B, C and D), with 2 additional optional cohorts of 8 subjects (Regimens E and F).

Part 2A is a double-blind (within cohorts), randomised, placebo-controlled, multiple ascending dose (MAD) study. It is planned to enrol 2 cohorts of 8 subjects (Regimens G and H). Part 2B is a double-blind (within cohorts), randomised, placebo-controlled, MAD study.

It is planned to enrol 3 cohorts of 12 subjects (Regimens I, J and K). The primary objective is to assess the safety and tolerability of a new long-acting amylin-analogue GUB014295. Secondary objectives are to characterize the pharmacokinetics (PK) of the long-acting amylin-analogue GUB014295 and to investigate if the long-acting amylin-analogue GUB014295 has possible pharmacodynamic effects measured as weight changes and changes in gastric emptying (paracetamol concentration) and changes in glucose, insulin, C-peptide, and glucagon during a mixed meal test.

Enrollment: 100 estimated patients

Sex: All

Ages: 18 to 65 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Males (Part 1 only) aged 18 to 55 years, and males and females (Part 2 only) aged 18 to 65 years inclusive at the time of signing informed consent

• Lean to overweight or obese but otherwise healthy males (Part 1 and 2) or nonpregnant, non-lactating females (Part 2 only)
• BMI of 22.0 to 32.0 kg/m2 for Part 1 and Part 2A, and a BMI of 27.0 to 35.0 kg/m2 for Part 2B, as measured at screening. Overweight or obese as assessed by BMI should be due to excess adipose tissue, as judged by the investigator
• Weight for males ≥70 kg and ≤110 kg (all parts), and for females ≥60 kg and ≤110 kg (Part 2A and 2B only) at screening

Exclusion criteria

• Serious adverse reaction or serious hypersensitivity to any drug or formulation excipients
• Presence or history of clinically significant allergy requiring treatment, as judged by the investigator. Hay fever is allowed unless it is active
• Known or suspected hypersensitivity or allergy to paracetamol
• Presence or history of clinically significant cardiovascular, renal, hepatic, dermatological, respiratory, neurological, psychiatric, malignant, metabolic, endocrinological, haematological or venereal disorder, as judged by the investigator
• Presence or history of any clinically relevant gastrointestinal diseases or symptoms of gastrointestinal disorders potentially affecting interpretation of study data.
• Presence or history of diseases associated with impaired calcium homeostasis and/or increased bone turnover (e.g. Paget´s disease, osteoporosis)
• History of major depressive disorder within 2 years prior to screening
• Subjects unable to take paracetamol for any reason
• Subjects who do not have suitable veins for multiple venepunctures/cannulation as assessed by the investigator or delegate at screening
• Subjects with tattoos or scars on the abdomen which may interfere with injection site assessments as determined by the investigator or delegate at screening
• Clinically significant abnormal clinical chemistry, haematology, coagulation or urinalysis as judged by the investigator. Subjects with Gilbert's Syndrome are not allowed.
• HbA1c ≥48 mmol/mol (≥6.5%) and/or fasting plasma glucose ≥7.0 mmol/L at screening
• Part 2B only: Subjects with haemoglobin <LLN at screening and/or admission
• Prolongation of the QTcF over 450 msec for males and 470 msec for females or any other clinically significant abnormal ECG results as judged by the investigator
• Supine blood pressure (after ≥5 min rest) <90 mmHg or >150 mmHg (systolic) and/or <50 mmHg or >90 mmHg (diastolic)
• Heart rate (ECG-recorded after ≥5 min rest) <45 or >90 beats per minute
• Positive hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab) or human immunodeficiency virus (HIV) 1 and 2 antibody results
• Evidence of renal impairment at screening, as indicated by an estimated glomerular filtration rate (eGFR) of <70 mL/min/1.73m2
• Part 2A and 2B only: Females who are pregnant or lactating (all female subjects must have a negative highly sensitive urine or serum pregnancy test)
• Subjects who have received any investigational medicinal product (IMP) in a clinical research study within the 90 days prior to Day 1, or less than 5 elimination half-lives prior to Day 1, whichever is longer
• Subjects who have previously been administered IMP in this study
• Donation of blood or plasma within the previous 3 months or loss of greater than 400 mL of blood
• Subjects who are taking, or have taken, any prescribed or over-the-counter drug or herbal remedies/vitamins in the 14 days before IMP administration.
• Paracetamol (up to 4 g per day) will be permitted except in the 48 h prior to the mixed meal tests on Day -1 and Day 4 (Part 1 Cohorts 2 to 6), Day 39 (Part 2A) and Day 81 (Part 2B) where paracetamol is not permitted.
• NSAIDs can be given at the discretion of the investigator to treat any AEs if necessary;
• Subject reports prior receipt of an amylin and/or calcitonin receptor agonist within the last 6 months
• History of any drug or alcohol abuse in the past 2 years
• Regular alcohol consumption >21 units per week
• A confirmed positive alcohol breath test at screening or admission
• Current smokers and those who have smoked within the last 12 months
• Current users of e-cigarettes and nicotine replacement products and those who have used these products within the last 12 months
• A confirmed breath carbon monoxide reading of greater than 10 ppm at screening or admission
• Confirmed positive drugs of abuse test result at screening or admission
• Anticipated change in lifestyle (such as eating, exercise or sleeping pattern) during the trial and/or clinically significant body weight change (≥5% self-reported change) or comprehensive dieting attempts (e.g. participation in a weight reduction program or treatment with any medication indicated for weight management) within the last 90 days prior to screening
• Subjects who do not agree to consume the liquid mixed meal
• Male subjects with pregnant or lactating partners
• Any disorder, unwillingness or inability, not covered by any of the other exclusion criteria, that the investigator evaluates might jeopardise the subject's safety or compliance with the protocol
