Clinical studies of WP1066 in pediatric medulloblastoma,
the most common malignant brain tumor in children.

Mayo Clinic
Clinical Studies in diffuse intrinsic pontine gliomas
(DIPG), a highly aggressive and difficult to treat brain
tumor that affects almost exclusively children.


Phase 1

Currently in a Phase I trial at MD Anderson for GBM and melanoma metastasized to the brain (WP1066 crosses the blood-brain barrier, or BBB); presently in the 3rd cohort of dose escalation evaluating safety and activity; planned surgical expansion to be able to assess tumor tissue directly after administration of WP1066 at the maximum tolerated dose (MTD) for direct confirmation of target inhibition.


Subsequent Studies

Glioblastoma(GBM) and melanoma brain metastases. Due to the importance of STAT3 in AML, a subsequent initiation of clinical studies in AML patients is planned in 2019-20.


Additional Indications

Additional indications include pancreatic cancer, lung cancer, renal cancer, melanomas resistant to BRAF inhibitors, breast cancer, and ovarian cancer.
