Frequently asked questions about FLYSYN

What is FLYSYN used for in Acute Myeloid Leukemia?

FLYSYN is an investigational monoclonal antibody being developed for Acute Myeloid Leukemia, specifically in patients who are MRD positive. It is designed as a targeted therapy in the oncology setting and has been studied in a Phase 1 clinical trial. It is not yet approved for commercial use.

What does FLYSYN target?

FLYSYN targets FLT3, a receptor tyrosine kinase. It is classified as an inhibitor of FLT3. By binding to FLT3, FLYSYN aims to interfere with signaling pathways that contribute to the survival and proliferation of leukemic cells in Acute Myeloid Leukemia.

Who is developing FLYSYN?

FLYSYN is being developed by Veraxa Biotech AG, a biopharmaceutical company. Veraxa Biotech AG trades under the ticker symbol VRXA. The company is responsible for the clinical development of FLYSYN in Acute Myeloid Leukemia.

What phase is FLYSYN in?

FLYSYN is in Phase 1 clinical development. It has completed one Phase 1 trial in patients with Acute Myeloid Leukemia. As an investigational product, FLYSYN has not received FDA approval and remains in clinical testing.

What clinical trials is FLYSYN in?

FLYSYN has been evaluated in a Phase 1 clinical trial, NCT02789254, titled FLYSYN in MRD Positive AML. The trial was completed and enrolled 31 participants in Germany. It was an uncontrolled, non-randomized study in adults aged 18 years and older.
