Dose Expansion - Overall Response Rate (ORR)
Up to 2 years

Percentage of participants with best overall response of complete response or partial response according to MPN IWG-MRT or MDS/MPN IWG criteria. Units: Percentage of participants

Dose Expansion - Complete Remission (CR) Rate
Up to 2 years

Percentage of participants achieving complete remission per IWG criteria. Units: Percentage of participants

Dose Expansion - Progression-Free Survival (PFS)
At 6 months and up to approximately 2 years

Time from first dose to disease progression or death from any cause. Units: Months

Dose Expansion - Overall Survival (OS)
Up to 2 years

Time from first dose to death from any cause. Units: Months

Dose Expansion - Platelet Count ≤400 ×10⁹/L Without Thromboembolic Events

Frequently asked questions about JBI-802

What is JBI-802 used for?

JBI-802 is an investigational small molecule being developed for the treatment of Essential Thrombocythemia (ET), a type of myeloproliferative neoplasm. It is also being studied in related conditions such as Myelodysplastic/Myeloproliferative Neoplasms (MDS/MPN) with thrombocytosis. The drug is administered orally and is currently in Phase 1 clinical development.

Who is developing JBI-802?

JBI-802 is being developed by cbdMD, Inc., a company traded on the stock exchange under the ticker symbol YCBD. The company is conducting clinical research to evaluate the safety and efficacy of this investigational drug for the treatment of myeloproliferative neoplasms, including Essential Thrombocythemia.

What phase is JBI-802 in?

JBI-802 is currently in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical trials to assess its safety and efficacy. The ongoing Phase 1/Phase 2 study is recruiting participants to evaluate the drug in patients with myeloproliferative neoplasms.

What clinical trials is JBI-802 in?

JBI-802 is being studied in a Phase 1/Phase 2 clinical trial with the identifier NCT07612280. This trial is assessing the safety and efficacy of orally administered JBI-802 in subjects with Myeloproliferative Neoplasms (MPN) and Myelodysplastic/Myeloproliferative Neoplasms (MDS/MPN) with thrombocytosis. The study is currently recruiting participants in Australia and has a target enrollment of 30 patients.

Is JBI-802 FDA approved?

JBI-802 is not FDA approved. It is an investigational drug currently in Phase 1 clinical development. The ongoing clinical trial is designed to evaluate its safety and efficacy, but the drug has not yet received regulatory approval for the treatment of Essential Thrombocythemia or any other condition.
