• NFC-1 (Drug), also known as NFC1: Doses of NFC-1 will be administered as 50, 100, 200, or 400 mg twice daily as size 2, hard gelatin capsules for oral administration.

Primary outcomes

• Time to symptom relapse [Through study completion, up to 5 weeks]

Secondary outcomes

• Response to treatment based on Clinical Global Impression - Improvement scale [Through study completion, up to 5 weeks]
• Safety and tolerability as determined by AEs, laboratory results, C-SSRS, and K-SADS [Through study completion, up to 5 weeks]

Sex: All, ages: 12 Years to 17 Years

Inclusion Criteria:

* Subject has a diagnosis of a 22q11.2 deletion prior to screening.
* Subject has a diagnosis of anxiety disorder and/or ADHD and/or ASD based upon diagnostic evaluations performed at screening, history, and clinical judgement.
* Subject is judged to be in general good health, other than having anxiety disorder and/or ADHD and/or ASD and 22q11DS. Medical conditions related to 22q11DS must be clinically stable post surgical correction and/or medical management.
* Subject has no clinically significant abnormality on 12-lead electrocardiogram (ECG) performed at screening or baseline such as serious arrhythmia, bradycardia, tachycardia, cardiac conduction problems, or other abnormalities deemed to be a potential safety issue.
* Subject and parent/legal guardian understand the study procedures and agree to the subject's participation in the study as indicated by parental/legal guardian signature on the subject informed consent form and subject's signature on the assent form.

Exclusion Criteria:

* Subject has a diagnosis of co-morbid major psychiatric disorders (ie, aside from anxiety disorder, ADHD, and/or ASD), including major depression, bipolar disease, schizophrenia (or any psychotic disorder), and moderate or severe intellectual disability, which in the opinion of the investigator may interfere with the conduct of study evaluations.
* Subject has an IQ < 65 as determined by the Wechsler Abbreviated Scale of Intelligence.
