Data in the abstracts will be related to two pipeline compounds, both in pre-clinical stages of development:
• ON 123300 is a first in class dual inhibitor of CDK4/6 and ARK5.
 • This compound is comparable to palbociclib (Pfizer's Ibrance®) which is approved for breast cancer and is considered a blockbuster.
 • Unlike palbociclib, our third-generation molecule has the potential to exhibit single agent activity and could be useful in many indications beyond breast cancer, including hematological cancers.
 • ON 123300 is covered by issued patents worldwide.
 • The presentation relates to efficacy in animal tumor model showing differentiation from palbociclib and potent anticancer activity.
 • This work was carried out by Onconova scientists and our collaborators working at Long Island University.
• ON 150030 is a dual inhibitor of Flt3 and Src kinases, both validated targets for treatment of AML and other cancers
 • ON 150030 is a Type I inhibitor, differentiated from Type II inhibitors like Quizartinib, which do not work against mutant kinases.
 • Dual specificity allows for targeting both AML as well as solid tumors.
 • This work was carried out by Onconova's founding scientists and colleagues, now working at Mount Sinai School of Medicine.
