Clinical Trial Summary

An open-label study designed to evaluate the safety, tolerability, and pharmacokinetics of ALA-1000 in opioid-dependent subjects. To characterize the PK profile of ALA-1000 in 5 single ascending dose cohorts and a sixth cohort of single ALA-1000 after receiving buprenorphine sublingual films for 7 days.

Description:

The study will include opioid-dependent subjects who have been receiving stable, orally administered buprenorphine for at least 2 weeks or buprenorphine naïve subjects who will be stabilized on orally administered buprenorphine for 3 days prior to ALA-1000 administration.

All subjects will be washed off of oral buprenorphine for 7 days prior to ALA-1000 administration except Cohort 6 which will receive ALA-1000 administration after 7 days of buprenorphine sublingual film dosing.

The subsequent cohorts will be initiated after safety and PK information from the preceding cohorts is available.

The expected maximum duration of participation for each subject is 192 days approximately, consisting of up to a 7-day screening period, up to a 31-day residential phase, and up to a 154-day nonresidential period.

Exclusion Criteria:

1. History or presence of a significant medical disease or disorder which, in the opinion of the investigator, increases the risk of the study drug or may confound the interpretation of study measures, as confirmed by screening laboratory results.

2. Clinically significant abnormal findings on physical examination, vital signs, or Electrocardiogram (ECG). Defined as having a QTc (Fridericia) interval > 470 msec or any other clinically significant abnormalities at screening, check-in, or prior to administration of ALA-1000.

4. History of suicidal behavior in the past 1 year or current suicidal ideation as per investigator judgement.

5. Currently meets Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for substance use disorder, moderate or severe for any substance other than opioids, caffeine, or nicotine.

6. Currently meets criteria for any unstable psychiatric disorder, including schizophrenia, schizoaffective, bipolar disorder (depression and stable bipolar disorder are not excluded if condition has been stable for at least 60 days).

7. Current diagnosis of Acquired Immune Deficiency Syndrome (AIDS) as confirmed by Western Blot and viral load laboratory results.

8. Acute active Hepatitis B or C as evidenced by positive serology and Aspartate aminotransferase (AST)/ Alanine aminotransferase (ALT) >2 upper limit of normal (ULN)

9. History of blood donation in excess of 450 mL within 30 days prior to Visit 1.

10. Received treatment with an investigational drug or device within 90 days prior to Visit 1.

11. Use of strong inhibitors or inducers of cytochrome P450 3A4 (CYP3A4) within 30 days prior to Visit 1.

12. Use of any new medication, vitamins, or supplements within 7 days prior to Visit.

13. Hypersensitivity or allergy to buprenorphine or other opioids which, in the opinion of the investigator, would compromise subject safety.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Incidence of AEs will be summarized by treatment overall, by severity, and by relationship to ALA-1000. Serious AEs and AEs leading to discontinuation of study drug will also be presented.		Baseline (prior to dosing) through the End of Study (Day175), or Early termination
Primary	Change of vital signs will be assessed in subjects receiving ALA-1000.	Vital signs including blood pressure, pulse rate, respiration rate, pulse oximetry and temperature. Systolic and diastolic blood pressure will be assessed while supine and standing. Pulse oximetry will be monitored continuously for 24 hours post injection to assess for any signs/symptoms of respiratory depression.	Baseline (prior to dosing) through the End of Study (Day175), or Early termination
Primary	Chang of clinical laboratory assessments (biochemistry, hematology and urinalysis) will be assessed in subjects receiving ALA-1000.	Samples will be collected for laboratory tests, including hematology, serum chemistry, urinalysis, serum/urine pregnancy test (conducted for females of childbearing potential only), and urine drug screen, to assess the safety of subjects.	Baseline (prior to dosing) through the End of Study (Day175), or Early termination
Primary	Change of ECG parameter of QTcF interval will be assessed in subjects receiving ALA-1000		Baseline (prior to dosing) through the End of Study (Day175), or Early termination
Primary	A standard physical examination will be performed to monitor the safety in subjects receiving ALA-1000	The examination will include assessment of skin, head, ears, eyes, nose, throat, neck, thyroid, lungs, heart, cardiovascular, abdomen, lymph nodes, and musculoskeletal system/extremities.
