Inclusion Criteria:

  • Participants has provided signed, informed consent before initiation of any study specific procedures
  • Aged ≥18 years at the time of signing the informed consent
  • Confirmed P/LP germline RUNX1 variant per ClinGen Myeloid Malignancy Variant Curation Expert Panel (MM-VCEP) RUNX1-specific variant curation rules80

  • Platelet count of ≥50,000/µL
  • Adequate renal function: estimated glomerular filtration rate based on Modification of Diet in Renal Disease (MDRD) calculation, >30 mL/min/1.73m2
  • Adequate hepatic function: aspartate aminotransferase (AST) and alanine aminotransferase (ALT) <3 × upper limit of normal (ULN) and total bilirubin <1.5 × ULN
  • Adequate cardiac function: left ventricular ejection fraction >50%

Exclusion Criteria:

  • Known allergy to sirolimus
  • History of lymphoma or other hematologic malignancies
  • Uncontrolled bleeding
  • Any prior diagnosis of myelodysplastic syndrome or other hematologic malignancy using International Working Group criteria
  • Prior treatment with sirolimus or a rapalog, mTOR inhibitor, or B-cell-depleting therapy within 28 days before study day 1

  • Known diagnosis of chronic viral infection (eg, hepatitis B or C or HIV, and Epstein-Barr) or tuberculosis
  • Women who are pregnant, may become pregnant, or who are breastfeeding

Interventions and Outcome Measures

Arms

experimental: Arm 1

Participants will visit the study clinic 2 times during Week 1, one (1) time during Weeks 2-4, and then 1 time every 2 weeks after that (Weeks 6, 8, 10, and so on) until Week 22 (Month 6). Then participants will have a follow-up visit at Week 24 and again at Week 52 (Month 12). Participants will take sirolimus by mouth every day, at about the same time each day. Swallow the tablet(s) whole with a full glass of water (about 1 cup). Do not crush or chew the tablet(s). Participants may take sirolimus with or without food.
