JSP191 is an investigative drug 2 and is not approved for any indication
Jasper is developing multiple therapies to transform the field of stem and cellular medicine
JSP191: First in class, targeted anti-CD117 antibody starting pivotal study in AML/ MDS
- Stem Cell Transplant for Cancer: AML/ MDS - Q1 2023 pivotal study start based on recent clinical data and regulatory feedback in older patients ineligible for full myeloablative conditioning
- Stem Cell Transplant for Rare Inherited Diseases: SCID - Potential near-term BLA and PRV opportunity; Fanconi Anemia - Initial clinical data w/ enrollment ongoing ; Sickle Cell - First clinical data in 2023
- Chronic Therapeutic for MDS and Mast Cell Diseases (e.g. Urticaria): First clinical data in 2023 for JSP191 as disease modifying therapeutic in low risk MDS; Potential to start additional mast cell studies
Jasper mRNA cell programming: Improving the efficacy and safety of cellular therapies
- Gene therapies: Jasper mRNAs designed to improve gene therapy engraftment leading to faster and higher levels of target protein
• Allogeneic grafts: Jasper mRNAs designed to eliminate need for toxic conditioning and reduce risk of GvHD to improve the therapeutic utility of donor grafts (matched, haploidentical or cord blood)
- Other: Potential uses in T- and NK cell therapies for homing and immune evasion
JSP191 is an investigative drug 3 and is not approved for any indication

JSP191 is an investigative drug 4 and is not approved for any indication
JSP191 is designed to specifically block Stem Cell Factor receptor signaling while minimizing adverse effects on mast, germ or Cajal (GI) cells
JSP191
Blocks SCF Binding to CD117
JSP191
SCF
CD117
Inhibition of Stem Cell Survival Signal leads to stem cell depletion in bone marrow
JSP191 designed to directly block Stem Cell Factor (SCF) from binding to the CD117 (Stem Cell Factor) Receptor with high affinity and avidity
- Aglycoslyated IgG1 antibody that inhibits SCF receptor signaling
- No Fc mediated ADCC or toxin mediated cytotoxicity to reduce risk of adverse effects on germ, mast and Cajal (GI) cells that express CD117
- Kd < 5pM affinity to human c-Kit Fc dimer with IC50 ~ 70pM
- Predictable clearance from ages 3 to 79, no need to monitor PK
- 6 month repeat dose NHP tox study complete
- Tested in over 125 healthy subjects and patients
- GMP production at commercial scale, validation ongoing
