Single and Multiple Doses of HA115 and Food Effect in Healthy Adult Volunteers

Randomized Double-Blind Placebo-controlled Ascending Dose FIH Study to Evaluate Single and Multiple Doses of HA115 in Healthy Volunteers and to Investigate Food Effect on Pharmacokinetics After Single Oral Doses of HA115

This is a randomized, double-blind, placebo-controlled Phase 1 study of HA115 capsules administered orally to healthy adult volunteers.

Study Overview

• Status: Withdrawn
• Conditions: Asthma
• Intervention / Treatment: Drug: Placebo; Drug: HA115

Detailed Description

The study consists of 2 parts, Part A (SAD, including fed/fasted comparison) and Part B (MAD). Part A will be a randomized, double blind, placebo controlled, dose-escalating titration of up to 8 single dose levels of HA115. In each cohort, 8 participants will receive active compound and 2 will receive placebo in a randomized manner. Part A will include an assessment of the effect of a high-fat breakfast on the absorption and PK profile of HA115, performed in 10 participants at a single dose to be selected based on SAD results and predicted to be associated with therapeutic plasma concentrations.

Part B will be a randomized, double-blind, placebo controlled parallel group study of up to 3 dose levels of HA115 given once daily. The number of days of dosing will be based on the results of the PK analysis from Part A. In each cohort, 8 participants will receive active compound fasted and 2 will receive placebo in a randomized, double blind fashion. Safety observations and PK evaluations will be made. Safety data will be reviewed with the SRC prior to each dose escalation.

8. Male participants who are nonsterilized and sexually active with a female partner of childbearing potential must agree to use a protocol-approved method of non-hormonal contraception as detailed in Appendix 4 from signing of the informed consent, throughout the duration of the study and for 30 days after the last dose of study drug.
9. Male participants must agree to not donate sperm during the study and for 3 months (90 days) after receiving the last dose of study drug.

Key Exclusion Criteria:

Has a history of or current clinically significant medical illness including (but not limited to) pulmonary, cardiovascular, coagulation disorders, lipid abnormalities, gastrointestinal, immunologic, endocrine, neurologic, psychiatric, or thromboembolic disease, metabolic disturbances, or any other current physical condition that the investigator considers should exclude the participant, or that could interfere with the interpretation of the study results.
2. Has current or recent (within 6 months) history of gastrointestinal disease (except for appendectomy, inguinal/umbilical hernia), or any surgical or medical condition such as Crohn's disease or liver disease, that could potentially alter the absorption, metabolism, or excretion of the study drugs.
3. Has any clinically significant medical condition, physical examination finding, ECG abnormality, or clinically significant abnormal value for clinical chemistry, hematology, coagulation, or urinalysis at Screening or at admission to the study center, as deemed appropriate by the investigator.

4. Has any of the following (participant may rescreen once for failure to meet criteria at Screening):

   • SBP >150 mmHg at Screening stable (measured in supine position)
   • DBP of >95 mmHg at Screening stable (measured in supine position).
5. History or presence of malignancy within the past 5 years, except for adequately treated localized skin cancer (basal cell or squamous cell carcinoma), which is allowed.

6. Currently suffers from clinically significant systemic allergic disease, or has a history of significant drug allergies, including but not limited to:

   • A history of anaphylactic reaction
   • Allergic reaction due to any drug that led to significant morbidity
7. Known hypersensitivity to any component of the formulation of HA115.
8. Has donated blood or had an acute loss of blood (>500 mL) during the 3 months before study drug administration or intends to donate blood or blood products within 3 months after the completion of the study.
