Brief Summary:
This is a Phase 1 single center, parallel group study to assess and compare the safety, tolerability, PK and PD of 4 single ascending doses of P1101 (100, 200, 300, and 450 μg) following subcutaneous administration in healthy Japanese and Caucasian subjects.

Condition or disease Intervention/treatment Phase
Healthy Volunteers Drug: ropeginterferon alfa-2b Phase 1

Detailed Description:

Twenty-four healthy eligible Japanese male subjects and 24 healthy eligible Caucasian male subjects, each divided into 4 cohorts of 6 subjects, will participate in this study. No subject will participate in more than 1 cohort and all subjects will receive a single dose of P1101. Caucasian subjects will be body weight- and height-matched to Japanese subjects.

Dosing will be initiated with the lowest dose of 100 μg in both Japanese and Caucasian subjects.

Criteria

Inclusion Criteria:

Subjects are eligible to be included in the study only if all of the following criteria apply:

  • Adult Japanese and Caucasian males aged 21 to 50 years inclusive and body mass index (BMI) between 19 and 30 kg/m2.
  • Japanese subjects must be first generation (born in Japan) with parents and grandparents born in Japan, lived for < 10 years outside of Japan, and have no significant change in life style since leaving Japan.
  • Caucasian subjects must have both parents of Caucasian descent; Caucasian subjects are defined as descendants of the original peoples of Europe.
  • Individual Caucasian subjects should be selected to match body weight (± 20%) and height (± 15%) of corresponding Japanese subjects.
  • Subjects must be willing to use effective methods of contraception during the entire study period and for 12 weeks after dosing on Day 1.
  • Subjects who are healthy as determined by pre-study medical history, physical examination, and 12-lead ECG.
  • Subjects whose clinical laboratory test results are within the reference ranges for hematological parameters and liver function tests at Screening and Day -1. For results outside the reference range at Screening and considered not clinically significant by the Investigator a repeat test is allowed once during the Screening period. Note: subjects with an absolute neutrophil count below 2.0 × 109/L will be excluded. All other clinical laboratory test results must be within the reference range or judged not to be clinically significant and acceptable to the Investigator.
  • Subjects whose thyroid function tests are within the study reference range.
  • Subjects who are negative for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis C virus antibody (HCVAb) and human immunodeficiency virus (HIV) I and II tests at Screening.
  • Subjects who are negative for drugs of abuse and alcohol tests at Screening. Alcohol will be measured using breathalyzer test. If the tests are negative at Screening, and if they meet other eligibility criteria, the subject may be included. A repeat test for suspected false positive at Screening (with documented rationale) may be performed at the discretion of the Investigator. However, if the tests are subsequently positive on Admission, the subject should be withdrawn from the study. Repeat tests are not allowed at Admission.
  • Subjects who are non-smokers for at least 6 months preceding Screening.
  • Subjects who are able and willing to give a valid written informed consent.

Exclusion Criteria:

Subjects are excluded from the study if any of the following criteria apply:

  • Subjects who do not conform to the above inclusion criteria.
  • Female subjects.

  • Subjects who have a first degree relative with autoimmune disease (e.g. thyroiditis, lupus, rheumatoid arthritis, etc.) or other clinically relevant medical history which in the opinion of the Investigator poses a risk to the subject.
  • Subjects with a history of latent or active tuberculosis or exposure to endemic areas.
  • Subjects with a positive result in the QuantiFERON-TB Gold test and/or clinically significant abnormality on chest X-ray.
  • Subjects who have a clinically relevant surgical history and history of any prior malignancy.
  • Subjects who, in the opinion of the Investigator, have clinically relevant medical history in their immediate family (first degree relative).
  • Subjects with current symptoms of eczema or hay fever, or subjects with a history of hay fever requiring medication when their hay fever season starts within the expected duration of the study.
  • Subjects who have a history of severe allergy and severe drug reaction (e.g., anaphylaxis, or other drug reaction requiring hospitalization to beta lactam antibiotics OR any other relevant drug hypersensitivity).
  • Subjects who have a history of alcoholism.
  • Subjects who consume more than the recommended number of 14 units of alcohol per week. (1 unit = 1 glass of wine [125 mL] = 1 measure of spirits = ½ pint of beer).
  • Subjects who have a history of drug abuse.
  • Subjects who have abnormal vital signs, after 10 minutes supine rest (measurements may be repeated after 15 minutes at the discretion of the Investigator where they suspect that the initial values are not representative of the usual values due to some factors e.g., anxiety), defined as any of the following at Screening:

    1. Systolic blood pressure < 90 mmHg or ≥ 140 mmHg;
    2. Diastolic blood pressure < 50 mmHg or ≥ 90 mmHg;
    3. Pulse rate < 40 or > 100 beats per minute.

  • Subjects who have received any live vaccine in the 6 months prior to Screening.
  • Subjects who have previously been exposed to interferon or peginterferon.
  • Subjects who have received the last dose of investigational product within the last 3 months or within 5 times the half-life, whichever is longer and those who are on extended follow-up.

  • Subjects who are staff members at the investigational site.
  • Subjects who are Contract Research Organization staff members, Sponsor employees, and affiliates.
