Study Summary

This trial will study the effects of liquid leucovorin calcium on young children with autism spectrum disorder. Enrollment will last approximately 26 weeks from screening to end of treatment.

Who is the study for?
This trial is for young children aged between 2.5 and 5 years with Autism Spectrum Disorder (ASD) who have language delays or impairments. They must not have changed their treatments for two months before the study and should maintain them throughout the trial. Children with severe prematurity, certain medical conditions, violent behavior, or allergies to the study product cannot participate.Check my eligibility
What is being tested?
The trial tests if liquid leucovorin calcium can improve cognitive abilities and behaviors related to ASD in children, focusing on language skills. It involves a comparison between leucovorin calcium and a placebo over approximately six months at two different sites.See study design
What are the potential side effects?
While specific side effects are not listed here, potential risks may include allergic reactions to ingredients in leucovorin calcium or placebo. Parents will be informed about any known side effects prior to participation.

Study Objectives

Outcome measures can provide a clearer picture of what you can expect from a treatment.
Primary outcome measures
Evaluate the change in measures of expressive language
Secondary outcome measures
Evaluate change in autism severity of specific symptoms
Autistic Disorder
Evaluate the change in adaptive functioning
+9 more
Other outcome measures
Combine presence of FRAA titers and single nucleotide polymorphisms (above) into a predicting equation that will evaluate the probability of positive response to L-leucovorin treatment.
Test if biomarkers (FRAAs) predict clinical response to L-leucovorin
Test if biomarkers (single nucleotide polymorphisms) predict clinical response to L-leucovorin

Trial Design

2Treatment groups
Experimental Treatment
Placebo Group
Group I: L-leucovorin calciumExperimental Treatment1 Intervention
The liquid form of leucovorin calcium will be dosed by weight, with a target dose of 1mg/kg/day, divided into two daily doses. This product may be taken alone or mixed with liquid. Participants randomized to this arm will receive active treatment for both 12-week phases of the study.
Group II: PlaceboPlacebo Group1 Intervention
The placebo will mimic the experimental treatment in flavor, odor, packaging, and dosing instructions. Participants randomized to this arm will receive placebo for the first 12 weeks of the study, then active treatment for the remaining 12 weeks.
