Tenalisib has been evaluated as an investigational new drug in number of early clinical studies in patients with relapsed/refractory hematological malignancies and demonstrated acceptable safety and promising efficacy in these patients. Since these advanced relapsed/refractory patients have limited therapeutic options, it is reasonable to continue Tenalisib in responding patients post completion of their participation in previous clinical studies.

Inclusion Criteria:

1. Patients must be currently receiving treatment with Tenalisib on a previously approved protocol.
2. Patients must have had at least one efficacy evaluation in previous study and should have achieved either SD, PR or CR.
3. Patients must have completed at least 6 cycles of Tenalisib in previous study
4. Ability to swallow and retain oral medication.
5. Female patients of child-bearing potential must consent to use two medically acceptable methods of contraception.
6. Male patients must be willing to use adequate contraceptive measures
7. Willingness and ability to comply with trial and follow-up procedures.
8. Willingness to provide new written informed consent.

Exclusion Criteria:

1. Patient has been discontinued from their previous Tenalisib study 4 weeks prior to entering the compassionate use trial.
2. Patient progressed while receiving Tenalisib therapy in his/her previous study.
3. Pregnant or lactating woman.
4. Inability or unwillingness to comply with study and/or follow-up procedures outlined in the protocol.
5. Concurrent condition that in the investigator's opinion would jeopardize compliance with the protocol.

Overall, 17 patients were enrolled in this study.

Any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. This includes AE, SAE and adverse event of special interest.

The primary purpose of this study is to offer patients, who completed a Rhizen-sponsored clinical study without progression, the opportunity to continue to receive Tenalisib on a compassion basis. Thus, the assessments were done in open-label manner.
