What is the mechanism of action of this treatment?

Common treatments for Autism Spectrum Disorder (ASD) include pharmacological interventions like folinic acid, which is being studied for its potential to improve language problems in children with ASD. Folinic acid, also known as leucovorin, is believed to enhance neurotransmitter function and support metabolic processes that are often disrupted in ASD. Other treatments, such as melatonin, are used to address sleep disturbances by regulating the sleep-wake cycle. Understanding these mechanisms is crucial as it helps tailor treatments to target specific symptoms, potentially improving the quality of life for ASD patients by addressing core deficits and associated challenges.

What side effects are associated with this type of intervention?

Common treatments for Autism Spectrum Disorder (ASD) include behavioral and educational interventions, complementary and alternative therapies (CAM), and pharmacologic treatments. CAM therapies often lack high-quality evidence and can interact with prescription medications, leading to potential side effects. Specific CAM therapies like gluten-free casein-free diets may cause nutritional deficiencies. Pharmacologic treatments such as melatonin can improve sleep but may increase seizure risk in children with epilepsy. Antipsychotics and mood stabilizers used for behavioral issues can cause weight gain, metabolic changes, and sedation.

What prior FDA approvals exist?

Currently, there are no FDA-approved medications specifically for improving language problems in children with Autism Spectrum Disorder (ASD). However, some medications are approved to address associated symptoms such as irritability and aggression. For example, risperidone and aripiprazole are FDA-approved for treating irritability in children with ASD. Folinic acid, also known as leucovorin, is being studied for its potential to improve language problems in children with ASD, but it is not yet FDA-approved for this use.

What other types of research exist?

Promising novel alternatives to folinic acid for treating language problems in children with autism spectrum disorder include Palmitoylethanolamide, which has shown potential in improving cognitive functions, behaviors, and sociability, and Omega-3 supplementation, which has anecdotal evidence of benefits despite mixed results in clinical trials. Additionally, prolonged-release melatonin has demonstrated efficacy and safety in managing sleep disturbances, which can indirectly benefit overall behavior and cognitive function in children with ASD.

Awards & highlights

Summary

This trial will test if folinic acid can help improve language skills in children with autism spectrum disorder.

Who is the study for?

This trial is for children aged 5 to less than 17.5 years with Autism Spectrum Disorder and language impairment, who speak English at home and have an IQ of at least 40 or a mental age of at least 18 months. They must be on stable speech therapy and educational plans, not planning medication changes for the study's duration, and not taking certain medications that affect folate metabolism.Check my eligibility

What is being tested?

The trial tests if folinic acid (leucovorin) can improve language problems in autistic children compared to a placebo. Folinic acid is FDA-approved for reducing chemotherapy side effects but its effectiveness in autism-related language issues is being investigated here over a period of up to 24 weeks.See study design

What are the potential side effects?

While the specific side effects are not listed here, as folinic acid is generally used during cancer treatment to reduce side effects from chemotherapy, it may be well-tolerated. However, potential risks will likely be monitored given its investigational use.

Experimental Treatment

Placebo Group

Group I: Folinic AcidExperimental Treatment1 Intervention

Subjects randomized to receive Folinic Acid will take Liquid levo-leucovorin via oral route. The target dose is 1 mg/kg/day with a maximum of 25 mg/day, divided in two daily doses. A two- to four-week supply of 15 ml vials will be dispensed in line with the visit schedule. With the exception of children in the lowest weight group (≥ 15 - < 20 kg) from days 1-14, parents will administer the prescribed dose twice a day at the same time each day.

Group II: Placebo ControlPlacebo Group1 Intervention

Subjects randomized to receive placebo will take placebo twice a day (Exception: children in the lowest weight group ( ≥ 15 - < 20 kg) will start once a day for Days1-13). The pattern of dose escalation will be the same as the active compound. After 12 weeks, the blind will not be broken and subjects will be offered treatment for a 12-week open-label extension phase.
