💬In plain words
What the trial is, and whether it could suit you
Background:
Autoimmune lymphoproliferative syndrome (ALPS) is a rare disorder of the immune system caused by a mutation in the FAS gene. In ALPS, the body stores too many germ-fighting cells called lymphocytes. This can lead to an enlarged spleen and lymph nodes. Current treatments for ALPS can have many adverse effects. Better treatments for ALPS are needed.
Objective:
To test a study drug (soquelitinib) in people with ALPS.
Eligibility:
People aged 16 years and older with ALPS.
Design:
Participants will have 8 clinic visits and 6 remote visits within 1 year.
Participants will be screened. They will have a physical exam with blood and urine tests. Some may have tests of their lung function.
Soquelitinib is a tablet taken by mouth twice a day. Participants will record their doses and any symptoms on a paper or online form.
Blood tests and other procedures will be repeated durin

5. If currently on corticosteroid therapy, then dose is less than 20 mg/day (prednisone equivalent) and has been stable for at least 4 weeks.
6. For participants to be seen at the NIH CC, co-enrolled on NIH protocol 93-I-0063.
7. Participants who can become pregnant or who can impregnate their partner must agree to either remain sexually abstinent or use two highly effective methods of contraception when engaging in sexual activities that can result in pregnancy, beginning 28 days before baseline until 3 months after the last dose.

EXCLUSION CRITERIA:
An individual who meets any of the following criteria will be excluded from participation or re-enrollment in this study:
1. Profound grade 3 or 4 cytopenias that cannot be improved with immunomodulatory treatments prior to enrolling in the clinical trial and starting the study drug. Per investigator discretion, individuals on a single agent may be included if the dose is stable for 12 weeks at screening and is not expected to confer additive toxicity.
2. Renal impairment, defined as serum creatinine \>1.5 mg/dL (or 133 micromol/L) or estimated glomerular filtration rate \<60 mL/min/1.73 m\^2.
3. Liver impairment, defined as bilirubin, alanine aminotransferase, or aspartate aminotransferase greater than 2.5 times the upper limit of normal.
4. History of EBV-associated lymphoma.
5. Active EBV infection with EBV load \>300 copies/mL.
6. Tuberculosis infection (active or latent) or undergoing tuberculosis treatment.
7. Infection with HIV or hepatitis B or C.
8. Current other invasive or systemic fungal, bacterial, or viral infection requiring therapy.
9. History of opportunistic infection within the previous 180 days.
10. History of invasive malignancy that required systemic therapy within the last 3 years.
11. Current use of moderate or strong cytochrome P450 isozyme (CYP)3A inhibitors or inducers that cannot be stopped before day 0.
12. Current use of P-glycoprotein (P-gp) inhibitors that cannot be stopped before day 0.
