A Study to Investigate the Pharmacokinetics, Safety, and Tolerability of Balovaptan in Children With Autism Spectrum Disorder

September 21, 2020 updated by: Hoffmann-La Roche

A Phase Ib, Multicenter, Open-Label, 6-Week Study With a 48-Week Extension to Investigate the Pharmacokinetics, Safety, and Tolerability of Balovaptan in Children Ages 2-4 Years With Autism Spectrum Disorder

This was a Phase Ib, multicenter, open-label study in children 2-4 years old with autism spectrum disorder (ASD) to investigate the pharmacokinetics, safety, and tolerability of an oral dose of balovaptan once a day (QD). The study was to consists of a 6-week treatment period to evaluate the pharmacokinetics of balovaptan in 2 to 4 year old children followed by an optional extension period of 48 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

2 years to 4 years (Child)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Diagnosis of ASD according to Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) criteria for ASD. Diagnostics will be performed by a team of autism experts and confirmed by Autism Diagnostic Observation ScheduleTM, Second Edition (ADOS-2) criteria. The DSM-5 criteria for diagnosis of autism must be met with the highest confidence in the opinion of the investigator. Children with ambiguous diagnostic results cannot be enrolled in the study. If the ADOS-2 assessment has been performed by a certified rater and documented within 12 months of the screening visit, it is not mandatory to repeat it unless the subject was assessed below an age of 2 years.
  • Hearing and vision compatible with the study assessments, as judged by the investigator
  • Ability for subject and the caregiver to comply with the study protocol, in the investigator's judgment
  • Availability of a parent or other reliable caregiver who is fluent in language of the site and has frequent and sufficient contact with the subject.

Exclusion Criteria:

  • Clinically significant psychiatric and/or neurologic comorbidity that may interfere with the safety or efficacy endpoints in the view of the investigator
  • Clinically significant regression of any acquired language and motor function skills in the opinion of the investigator throughout the subject's development
  • History of seizures with the exception of a single, non-complicated febrile seizure >= 6 months before screening
  • Clinical diagnosis of peripheral neuropathy or signs and symptoms indicative of peripheral neuropathy
  • Any clinically relevant cardiovascular disease
  • Confirmed elevation in cardiac troponin I (cTn I), high-sensitive cardiac troponin T (hs cTn T), N-terminal pro-B-type natriuretic peptide (NT-proBNP) or, if conducted, clinically relevant abnormality in Doppler echocardiogram
  • Confirmed clinically significant abnormality on ECG at screening, including, but not limited to, a QT interval corrected through use of Fridericia's formula (QTcF) of >= 450 ms, absence of dominating sinus rhythm, or second- or third-degree atrioventricular block
  • Confirmed systolic or diastolic blood pressure above the 95th percentile or below the 5th percentile according to the Centers for Disease Control and Prevention (CDC) norm tables referring to stature (height)-for-age percentiles
  • Confirmed heart rate: >150 bpm in 2-year old children, >135 bpm in 3-year old children, or >120 bpm in 4-year old children.
  • Concomitant disease or condition that could interfere with, or treatment of which might interfere with, the conduct of the study; or discontinuation of prohibited medication that might pose unacceptable risks to the subject in the opinion of the investigator
  • Evidence for current GI disease that would interfere with the conduct of the study or pose unacceptable risks in the opinion of the investigator
  • History of coagulopathies, bleeding disorders, or blood dyscrasias
  • Positive serology for HIV-1 or HIV-2
  • Confirmed clinically significant abnormality in parameters of hematology, clinical chemistry, coagulation, or urinalysis, specifically a confirmed absolute neutrophil count (ANC) <LLN Children with confirmed CPK elevations exceeding 2 x upper limit of normal (ULN) will be excluded
  • History of malignancy
  • Clinically significant loss of blood within 3 months prior to screening
  • Unstable use of permitted medications for 4 weeks before screening
  • Use of prohibited medications within 30 days (or 5 times the half-life, whichever is longer) prior to initiation of study treatment
