• Currently receiving treatment with hematopoietic stimulating agents; the last dose must have been administered at least 90 days before starting study drug;
• Received treatment on another investigational trial within 90 days prior to start of study drug or plans to participate in another investigational drug trial;
• Taking medications that are strong inhibitors of CYP3A4/5 or strong inducers of CYP3A4 that cannot be stopped in an acceptable timeframe before starting study drug (timeframe will be discussed with your doctor).
