Concomitant malignancies or previous malignancies with less than a 1-year disease free interval at the time of signing consent.

Pregnant women are excluded from this study because APR-246 has not been studied in pregnant patients. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with APR 246, breastfeeding should be discontinued if the mother is treated with APR-246.

Patients with active uncontrolled infections
