简要总结
Protocol Title:
A Phase 1, first-in-human, randomized, double-blind, single-dose, parallel-group, 3-arm study comparing the pharmacokinetic, safety, tolerability, and immunogenicity profiles of AVT04, EU approved Stelara®, and US-licensed Stelara® in healthy adult subjects
Short Title:
A first-in-human randomized, double-blind study to compare AVT04 with EU-approved Stelara and US-licensed Stelara as a single-dose subcutaneous injection in healthy adult subjects
Rationale:
Alvotech (hereafter, the Sponsor) is developing AVT04 globally as a proposed biosimilar to the reference product Stelara (ustekinumab) for subcutaneous (SC) use. This is a first-in-human (FIH) clinical study with AVT04. The study aims to demonstrate pharmacokinetic (PK) similarity of the proposed biosimilar test product AVT04 and the reference products EU approved Stelara and US-licensed Stelara, in addition to evaluating the safety and tolerability of AVT04, when administered as a single 45 mg/0.5 mL SC dose.
详细描述
Overall Design:
This study is designed as a FIH, multicenter, randomized, double-blind, 3-arm, parallel-group study of AVT04 compared with EU-approved and US-licensed Stelara when administered as a single 45 mg/0.5 mL SC injection in healthy adult subjects.
Subjects will undertake a Screening visit between Day -28 and Day -1 to determine their eligibility in the study. Subjects who meet the eligibility criteria will be admitted to the study site on the day prior to dosing (Day -1), during which their continued eligibility will be assessed up to Day 1 prior to dosing. On Day 1, eligible subjects will be randomized and will receive a single dose of one of the following: AVT04, US licensed Stelara, or EU approved Stelara.
A staggered sentinel dosing strategy will be implemented as a safety measure, with equal numbers of subjects randomized to each treatment: Sentinel Group 1 (n = 3 subjects [1 per group]), Sentinel Group 2 (n = 6 subjects [2 per group]), and Sentinel Group 3 (n = 9 subjects [3 per group]). Following investigational product (IP) administration, there will be at least 72 hours of close observation and safety monitoring by the Principal Investigator (PI) for each subject and between sentinel groups (ie, 72 hours should have elapsed following IP administration for the last subject in each sentinel group). Provided there are no significant safety or tolerability concerns (or events that meet the study stopping criteria) in the previous sentinel group following a safety review and discussion between the PI, Medical Monitor, and Sponsor, the next sentinel group of subjects will be randomized and dosed. Once the IP dose is deemed to be safe and well tolerated in all 3 sentinel groups, the remaining subjects (n = 276 subjects [92 subjects per group]) will be randomized and dosed.
Sentinel subjects will remain confined to the study site from Day -1 to Day 4 (72 hours postdose); all remaining subjects will be confined to the study site from Day -1 up to Day 2 (24 hours postdose). Following dosing, PK, safety, tolerability, and other assessments will be performed according to the Schedule of Assessments. Subjects will return to the study site on an outpatient basis daily up to Day 12, then once a week from Day 15 to Day 64, followed by once every 2 weeks up to Day 78, and finally on Day 92 for the End-of-Study (EOS) visit.

入选标准
- •Subjects are eligible to be included in the study only if all of the following criteria apply at any time starting from Screening up to Day 1 prior to IP administration:
- •Capable of giving signed informed consent as described in Appendix 1, which includes compliance with the requirements and restrictions listed in the Informed Consent Form (ICF) and in this protocol.
- •Male or female subjects.
- •Subjects must be 18 to 55 years old inclusive, at the time of signing the ICF.
- •Have a body weight of 60.0 to 90.0 kg (inclusive) and body mass index (BMI) of 18.5 to 30.0 kg/m2 (inclusive).
- •For Japanese subjects only Is a second-generation Japanese person living abroad and both parents and grandparents are of Japanese origin, OR Was born in Japan and both parents and grandparents are of Japanese origin.
- •Medical history without major pathology, according to the PI's judgment.
- •Resting supine systolic blood pressure (BP) of ≤140 mm Hg and diastolic BP of ≤90 mm Hg; other vital signs showing no clinically relevant deviations according to the PI's judgment.
- •Computerized (12-lead) electrocardiogram (ECG) recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the PI.
- •Glycated hemoglobin (HbA1c) ≤42 mmol/mol.
- •Clinical safety laboratory results are within the reference ranges or showing no clinically relevant deviations as judged by the PI.
- •Have a negative urine drug screen (opiates, methadone, cocaine, amphetamines [including ecstasy and methamphetamines], cannabinoids, barbiturates, and benzodiazepines) and a negative alcohol breath test.
- •Tested negative for TB, hepatitis B surface antigen (HBsAg), hepatitis B core antibodies (anti-HBc), anti-hepatitis C virus (HCV) antibodies, and anti-human immunodeficiency virus (HIV) 1/2 antibodies at Screening.
- •Nonsmoker or occasional smoker, ie, smokes ≤10 cigarettes (or equivalent of tobacco- or nicotine containing products) per week within 3 months of Screening, and ability and willingness to refrain from smoking during confinement at the study site.
- •Ability and willingness to abstain from alcohol from 48 hours prior to drug administration, during confinement at the study site until discharge, and 24 hours prior to ambulatory visits.
- •Female subjects are eligible to participate if they are not pregnant (see Appendix 3), not breastfeeding, and at least ONE of the following conditions applies:
- •Is not a woman of childbearing potential (WOCBP), defined as:
- •Surgically sterile (documented hysterectomy, bilateral salpingectomy, or bilateral oophorectomy, as confirmed by review of the subject's medical records, medical examination, or medical history interview), or Postmenopausal (defined as no menses for 12 months without an alternative medical cause. A high follicle-stimulating hormone [FSH] level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy [HRT]. However, in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient). Female subjects on HRT and whose menopausal status is in doubt will be required to use 1 of the non estrogen hormonal highly effective contraception methods (Appendix 3) from Screening (signing the ICF) until at least 13 weeks after IP administration if they wish to continue their HRT during the study. Otherwise, they must discontinue HRT to allow confirmation of postmenopausal status before study enrollment.
