A Two-Part Single and Multiple Ascending Dose Trial of the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of LBT-3627 in Healthy Participants and in Participants With Parkinson's Disease.

PHASE1RECRUITING

Phase I a/b SAD/MAD study to evaluate safety and tolerability of LBT-3627 in both healthy volunteers and Parkinson's patients.

Simpliy with AI

Study details:

Evaluate the safety and tolerability of LBT-3627 in both a single and multiple ascending dose study. Phase Ia will explore safety and tolerability first in healthy volunteers then followed by Parkinson's patients after a single dose. Dose levels will escalate per cohort.

Phase Ib will explore safety and tolerability in Parkinson's patients after multiple doses. Dose levels will escalate per cohort.

Inclusion criteria

Heart rate in the range of 50 to 100 beats/minute after 5 minutes rest in supine/semi-supine position, and subsequently after 3 minutes of standing position. Note: Participants with orthostatic hypotension are not permitted. Orthostatic hypotension is defined as ≥ 30 beats/minute increase in heart rate between supine/semi-supine versus subsequent standing measurements. Body temperature (tympanic), between 35.5°C and 37.5°C. Electrocardiogram (ECG) without clinically significant abnormal including QT interval corrected for Fredericia (QTcF) < 450 msec for male participants and < 470 msec for female participants. No clinically significant findings in serum chemistry, haematology, coagulation or urinalysis (in the opinion of the Investigator).

Female participants must be of non-child-bearing potential i.e., surgically sterilised (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before the screening visit) or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause and a follicle-stimulating hormone [FSH] level consistent with postmenopausal status, per local laboratory guidelines), or, if of child-bearing potential: Must have a negative serum pregnancy test at the screening visit and a negative urine pregnancy test on Day -1, prior to dose administration. Must agree not to donate ova or attempt to become pregnant from the time of signing consent until at least 30 days after the last dose of study drug. If not exclusively in a same-sex relationship, must agree to remain abstinent throughout the study, or must agree to use adequate contraception (which is defined as use of a condom by the male partner combined with use of a highly effective method of contraception from one month prior to screening until at least 30 days after the last dose of study drug.

Male participants must: Agree not to donate sperm from the time of signing consent until at least 30 days after the last dose of study drug. If engaging in sexual intercourse with a female partner who could become pregnant, agree to use adequate contraception (defined as use of a condom plus a highly effective method of contraception from the time of signing consent until at least 30 days after the last dose of study drug. If engaging in sexual intercourse with a female partner who is not of childbearing potential or a same-sex partner, agree to use a condom from the time of signing consent until at least 30 days after the last dose of study drug.

Willing and able to comply with all scheduled visits, treatment plans, laboratory tests and other study procedures.

Note: Participants with well-controlled asthma (and is not receiving inhaled or oral steroids) is permitted, per PI (or delegate) discretion. Participants with well controlled, mild depression or anxiety, with no change in medication within the past 3 months is permitted, per PI (or delegate) discretion.

History of surgery or hospitalisation within 12 weeks prior to screening, or surgery planned during the study.

Lack of suitable veins for multiple venepunctures/cannulations as assessed by the Investigator or delegate at screening.

Presence of any tattoos or scarring which (in the opinion of the Investigator [or delegate]) would interfere with injection site reaction assessments.

Laboratory results at screening that indicate inadequate renal function (estimated creatinine clearance above the ULN or below the LLN, as calculated by the Cockcroft and Gault formula).

Liver function test results elevated more than 1.5-fold above the ULN for gamma glutamyl transferase (GGT), alkaline phosphatase (ALP), aspartate aminotransferase (AST) or alanine aminotransferase (ALT). Volunteers with ALP and/or ALT/AST above the limits specified may be included, at the discretion of the Investigator, if the levels are unaccompanied by clinical signs and are determined to be normal variants.

Liver function tests outside the normal range for bilirubin (more than 1.5-fold above the ULN for total bilirubin).

Participant has a positive cotinine test upon admission to the clinic on Day -1.

Participant smokes more than 5 cigarettes or equivalent per week, and/or participant is unwilling to abstain from smoking for 72 hours prior to check-in on Day -1 and throughout the confinement period at the study site.

Participant is breastfeeding or pregnant, or planning to breastfeed or become pregnant during the study.

Known substance abuse or medical, psychological, or social conditions that, in the opinion of the PI (or delegate), may interfere with the participants inclusion in the clinical study or evaluation of the clinical study results.

Participant has donated blood/blood products, experienced significant (> 500 mL) blood loss within 3 months prior to the first dose administration or receipt of a blood transfusion within 1 year prior to the first dose administration.

Any other condition or prior therapy that in the opinion of the Investigator (or delegate) would make the participant unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likelihood of noncompliance with any study requirements.
