Pharmacokinetics, Safety and Tolerability Study of AVT04 to EU Approved and US Licensed Stelara (Ustekinumab)

• Status: Recruiting
• Trial end date: 2022-07-28
• Target enrollment: 0
• Participant gender: All

Summary

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.

Criteria

Inclusion Criteria:

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:

1. 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.

2. Male or female subjects.

3. Subjects must be 18 to 55 years old inclusive, at the time of signing the ICF.

4. 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).

5. 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.

6. Medical history without major pathology, according to the PI's judgment.

7. 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.

8. Computerized (12-lead) electrocardiogram (ECG) recording without signs of clinically relevant pathology or showing no clinically relevant deviations as judged by the PI.

9. Glycated hemoglobin (HbA1c) ≤42 mmol/mol.

10. Clinical safety laboratory results are within the reference ranges or showing no clinically relevant deviations as judged by the PI.

11. Have a negative urine drug screen (opiates, methadone, cocaine, amphetamines [including ecstasy and methamphetamines], cannabinoids, barbiturates, and benzodiazepines) and a negative alcohol breath test.

12. 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.

13. 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.

14. 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.

15. 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:

1. 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.

2. Is a WOCBP who agrees to use a highly effective method of contraception (Appendix 3) consistently and correctly from Screening (signing the ICF) until at least 13 weeks after IP administration.

16. Nonsterilized male subjects with female partners of childbearing potential are eligible to participate if they agree to ONE of the following from Screening (signing the ICF) until at least 13 weeks after IP administration:

1. Are abstinent from penile-vaginal intercourse as their usual and preferred lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent.

2. Agree to use a male condom and have their partner use of a contraceptive method with a failure rate of <1% per year as described in Appendix 3 when having penile-vaginal intercourse with a WOCBP who is not currently pregnant.

3. Male subjects with a pregnant or breastfeeding partner must agree to remain abstinent from penile vaginal intercourse or use a male condom during each episode of penile penetration.

17. In addition, male subjects must refrain from donating sperm from Screening (signing the ICF) until at least 13 weeks after IP administration.

Exclusion Criteria:

Subjects are excluded from the study if any of the following criteria apply at any time starting from Screening up to Day 1 prior to IP administration:

1. Have a history of relevant drug and/or food allergies.

2. Have a history of hypersensitivity to Stelara, AVT04, or their constituents.

3. Have a known history of previous exposure to IL-12 and/or IL-23 inhibitors.

4. Have any past or concurrent medical conditions that could potentially increase the subject's risks or that would interfere with the study evaluation, procedures, or study completion. Examples of these include medical history with evidence of clinically relevant pathology (eg, malignancies or demyelinating disorders).

5. Presence of chronic obstructive pulmonary disease. Childhood asthma is allowed.

6. Presence of type 1 or 2 diabetes mellitus.

7. Have a known history of active or latent TB, except for subjects with documented and complete adequate treatment of TB or initiation (>1 month) of adequate prophylaxis of latent TB, with an isoniazid-based regimen.

8. Have resided or traveled in regions where tuberculosis and mycosis are endemic within 90 days before Screening, or who intend to visit such a region during the study period or within 3 months (12 weeks) after dosing.

10. Participation in a clinical study with an IP within 60 days or 5 half-lives of that IP (if known), whichever is longer, prior to IP administration in the current study.

Treatment with nontopical medications (including over-the-counter [OTC] medications and herbal remedies such as St. John's Wort extract) within 7 days or 5 half lives of the drug (whichever is longer) prior to IP administration, with the exception of multivitamins, vitamin C, food supplements and a limited amount of acetaminophen (up to 2 g in 24 hours, but <1 g in 4 hours) or ibuprofen (<1.2 g per day), which may be used throughout the study.

12. Have received live vaccines during the past 4 weeks before Screening or have the intention to receive vaccination during the study period or within 13 weeks after dosing.

13. Donation of more than 500 mL of blood within 8 weeks prior to drug administration.

14. History of alcohol abuse (with an average intake exceeding 10 drinks/week for women and 15 drinks/week for men: 1 drink = 360 mL of beer, 150 mL of wine, or 45 mL of spirits) or drug addiction (including soft drugs like cannabis products).
