Study to Evaluate the Safety and Tolerability of AD-NP1 in Healthy Human Adult Volunteers

About

Brief Summary

This is a Phase 1 single-blind, placebo-controlled, dose-escalation study designed to evaluate the safety of AD-NP1, a humanized monoclonal antibody targeting human ectonucleotide pyrophosphatase/phosphodiesterase-1 (ENPP1). The study aims to assess the maximum tolerated dose (MTD), pharmacokinetics (PK), pharmacodynamics (PD), and immunogenicity of AD-NP1 in healthy volunteers. Participants will be randomized to receive either AD-NP1 or placebo, with safety and efficacy monitored in accordance with Good Clinical Practice (GCP) guidelines. The study also seeks to explore changes in health-related quality of life (HRQOL) during the trial.

  • Sexually active male subjects must use a barrier method of contraception during the study
  • Screening laboratory values must meet the following criteria:
    • WBC (>3,000 - <11,000/mm^3)
    • Platelets (>100,000/mm^3)
    • Hemoglobin (>10.5 gm/dl)
    • Creatinine (<1.1 x upper limit of normal [ULN])
    • BUN (<1.25 x ULN)
    • AST (<1.1 x ULN)
    • ALT (<1.1 x ULN)
    • Alkaline Phosphatase (<1.1 x ULN)
    • Bilirubin (<1.1 x ULN)
    • Glucose-non-fasting (> 60 mg/dl and < 115 mg/dl)
  • Human immunodeficiency virus (HIV)-infected individuals on effective antiretroviral therapy with undetectable viral load within 6 months are eligible for this trial
  • For subjects with evidence of chronic hepatitis B virus (HBV) infection, the HBV viral load must be undetectable on suppressive therapy, if indicated
  • Individuals with a history of hepatitis C virus (HCV) infection must have been treated and cured. For individuals with HCV infection who are currently on treatment are eligible if they have an undetectable HCV viral load

Exclusion Criteria:

  • Previous exposure to humanized or human monoclonal antibodies whether FDA approved or investigational
  • Weight > 90 kg
  • History of any of the following illnesses or conditions:
  • a. Respiratory condition (such as asthma requiring daily medication)
  • b. Clinically immunocompromised due to any primary immune or autoimmune deficiency, as a result of chronic disease, cancer or medication used to treat these diseases
  • c. Blood dyscrasias
  • d. Psychiatric disorder that precludes compliance with the clinical protocol
  • e. Hepatitis
  • Any chronic condition requiring daily prescription or over-the-counter medicine except for vitamins and birth control products
  • History of drug or alcohol abuse within previous 12 months or a positive urine toxicology screen within 24 hours of initial screening
  • History of a previous severe allergic reaction with generalized urticaria, angioedema, or anaphylaxis
  • Physical finding on examination considered clinically significant such as heart murmur (other than functional), hepatosplenomegaly, lymphadenopathy, or focal neurological deficit
  • Urinalysis positive for > trace protein, >5 RBC/HPF or >5 WBC/HPF
  • Positive serology for HIV antibody, HCV antibody or Hepatitis B surface antigen
  • Positive serum pregnancy test during screening or positive urine pregnancy test within 24 hours of monoclonal antibody administration, or an unwillingness to undergo pregnancy testing
  • Currently breast-feeding
  • Receipt of an FDA approved vaccine or any investigational study agent within previous 30 days
  • Any other condition that in the opinion of the investigator would jeopardize the safety or rights of the subject participating in the study
