Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: A Single Center, Randomized, Double-Blind, Placebo-and Positive-Controlled, Interleaved, Ascending Single Dose Study to Explore the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of Oral AHTT956 in Healthy Subjects

Further study details as provided by Novartis:

Primary Outcome Measures:
  • Safety, tolerability of ascending single doses of AHT956 in healthy subjects
  • MTD (Maximum Tolerated Dose)

Secondary Outcome Measures:
  • Pharmacokinetics of single oral doses of AEB071
  • Inhibition of T-cell function and lymphocytes proliferation following single rising oral of AHT956
  • Pharmacokinetic/pharmacodynamic relationship of single rising oral doses of AHT956 at the end of study
  • Identify gene expression patterns of blood cells

  • Subjects who received live vaccine 4 weeks prior to dosing, any prescription drug use with 4 weeks prior to dosing, or over-the-counter medication use within 2 weeks prior to dosing.
  • Participation in any clinical investigation within 4 weeks prior to dosing or longer if required by local regulations, and for any other limitation of participation based on local regulations.
  • Donation or loss of 400 mL or more of blood within 8 weeks prior to first dosing, or longer if required by local regulation.
  • Flu-like symptoms or significant within two weeks prior to dosing.
  • A past medical history of clinically significant abnormality detected during electrocardiogram (ECG) examination or an evident family history (grandparents, parents and siblings) of a ECG abnormality (i.e. prolonged QT-interval syndrome).
  • History of fainting, hypotension when standing up, arrhythmia.
  • History of acute or chronic bronchospastic disease (including asthma and chronic obstructive pulmonary disease (including asthma and chronic obstructive pulmonary disease, treated or not treated).
  • History of clinically significant drug allergy or history of atopic allergy, urticaria, eczematous dermatitis). A known hypersensitivity to the study drugs or drugs similar to the study drugs.
  • Any history of surgical or medical condition(s) which could change the absorption, distribution, metabolism or excretion of drugs or which may jeopardize the subject, including history of gastrointestinal, pancreatic, liver, kidney, bladder, blood, or immune systems.
  • History of drug or alcohol abuse within the 12 months prior to dosing or evidence of such abuse as indicated by the laboratory assays conducted the screening or baseline evaluations.
