The company'slead project, obatoclax, is a pan Bcl-2 inhibitor which is active across allBcl-2 proteins, especially Mcl-1, a dominant protein. The drug has also shownto be effective reinitiating apoptosis and inducing autophagy, orself-digestion, of cancer cells. Currently, obatoclax is in Phase I and PhaseII trials, including a Phase IIb clinical trial composed of over 160 patientswith extensive stage small cell lung cancer and evaluating the efficacy andsafety of the drug in combination with standard chemotherapy. Trial enrollmentwas completed in November 2009.

Buchi says that he is "particularly excited" aboutobatoclax, adding that if it is successful, it has "the potential tosignificantly benefit patients suffering from small cell lung cancer, adevastating disease for which current treatments are limited and additionaltherapies are desperately needed."

"Gemin X and our investors have been very excited by thepromise and potential of our obatoclax program in patients with extensive stagesmall cell lung cancer, a condition for which there has been no change in thestandard of care for 25 years," says Peter R.
