A Study to Investigate the Pharmacokinetic Profile of ALXN2050 Modified Release Prototype Formulations and Immediate Release Reference Tablet in Healthy Adult Participants

A Two-Part Phase 1 Study to Evaluate the Pharmacokinetic Profile of ALXN2050 Modified Release Prototype Formulations and Immediate Release Reference Tablet in Healthy Adult Participants

The primary objectives of this study are to investigate the relative bioavailability and PK (Pharmacokinetic) profile of 2 ALXN2050 MR (Modified Release) formulations in comparison with the IR (Immediate Release) formulation.

Participation Criteria

Eligibility Criteria

• Ages Eligible for Study: 18 years to 55 years (Adult)
• Accepts Healthy Volunteers: Yes

Description

Inclusion Criteria:

• Healthy males or non-pregnant, non-lactating healthy females.
• Participants who are overtly healthy as determined by medical evaluation including medical history, physical or neurological examination, vital signs, 12-lead ECG, screening clinical laboratory profiles (hematology, biochemistry, coagulation, and urinalysis), as deemed by the Investigator or designee.
• BMI within the range of 18.0 to 30.0 kg/m2 (inclusive), with a minimum body weight of 50.0 kg at screening.
• Female participants of childbearing potential and male participants must follow protocol-specified contraception guidance.

Exclusion Criteria:

• History of clinically significant respiratory, cardiovascular, dermatological, hepatic, renal, GI, endocrinological, hematological, psychological, psychiatric, or neurological disorders capable of significantly altering the absorption, metabolism, or elimination of drugs; constituting a risk when taking the study intervention; or interfering with the interpretation of data.
• History of meningococcal infection.
• History of clinically significant hypersensitivity reactions to commonly used antibacterial agents, including beta lactams, penicillin, aminopenicillins, fluoroquinolones (specifically including ciprofloxacin), cephalosporins, and carbapenems, which in the opinion of the Investigator would make it difficult to properly provide either empiric antibiotic therapy or treat an active infection.
• History of clinically significant hypersensitivity or idiosyncratic reaction to the study drugs or related compounds.
• History of significant multiple and/or severe allergies (eg, drug, latex allergy, band aids, adhesive dressing, or medical tape). Hay fever is allowed unless it is active.
• History of seizures including childhood seizures.
• History of significant head injury, or head trauma requiring medical evaluation.
• History of malignancy within 5 years of screening, with the exception of non-melanoma skin cancer or carcinoma in situ of the cervix that has been treated with no evidence of recurrence.
• Any previous procedure, including history of stomach or intestinal surgery or resection, cholecystectomy, gallstones, TIPS, or surgical shunt, that could alter absorption or excretion of orally administered drugs.
• Significant current or chronic history of liver disease.
• Known hepatic or biliary abnormalities (with the exception of Gilbert's syndrome).
