They must also be prepared to contin-ue birth control measures for at least 1 month after terminating treat-ment.~* women of childbearing potential must have a negative pregnancy test at screening~* Men must agree to use an acceptable method of contraception (fort themselves or female partners as listed above) for the duration of the study. Men must agree to use a double barrier method of birth control and to not donate sperm during the study and for 1 month after receiving the last dose of study drug.~Male even if surgically sterilized (i.e., status postvasectomy) must agree to 1 of the following:~* practice effective barrier contraception during the entire study treatment period and through 1 months after the last dose of study drug, or~* agree to practice true abstinence, when this is in line with the preferred and usual lifestyle of the subject. (Periodic abstinence \[e.g., calendar, ovulation, symptothermal, postovulation methods for the female part-ner\] and withdrawal are not acceptable methods of contraception)~Exclusion criteria~* Histological diagnosis different from BCL-2 positive PTCL-NOS, AITL, and TFH~* Allogeneic or autologous stem cell transplant within 6 months prior to the informed consent signature~* Treatment with any of the following within 7 days prior to the first dose of study drug:~* steroid therapy for anti-neoplastic intent~* moderate or strong cytochrome P450 3A (CYP3A) inhibitors (see Ap-pendix C for examples)~* moderate or strong CYP3A inducers (see Appendix C for examples)~* Subject has received any anti-cancer therapy including chemotherapy, immunotherapy, radiotherapy, investigational therapy, including targeted small molecule agents within 14 days prior to the first dose of study drug~* History of CNS involvement by lymphoma~* Administration or consumption of any of the following within 3 days prior to the first dose of study drug:~* grapefruit or grapefruit products~* Seville oranges (including marmalade containing Seville oranges)~* star fruit~* Previous treatment with a BCL-2 family protein inhibitor~* Subject is known to be positive for HIV (HIV testing is not required)~* Cardiovascular disease (NYHA class ≥2)~* Creatinine Clearance \< 30 mL/min~* Significant history of neurologic, psychiatric, endocrinologic, metabolic, immunologic, or hepatic disease that would preclude participation in the study or compromise ability to give informed consent.~* Any history of other active malignancies within 3 years prior to study en-try, with the exception of adequately treated in situ carcinoma of the cer-vix uterine, basal cell carcinoma of the skin or localized squamous cell carcinoma of the skin, previous malignancy confined and surgically re-sected with curative intent.~* Subject who has malabsorption syndrome or other condition which pre-cludes enteral route of administration.~* Evidence of other clinically significant uncontrolled condition(s) including, but not limited to uncontrolled and/or active systemic infection (viral, bac-terial or fungal)~* Active HBV positive hepatitis~* The following categories of patients HBV positive but with non evidence of active hepatitis may be considered for the study:~* HBsAg positive with HBV DNA \< 2000 UI/ml (inactive carriers); HBV DNA \> 2000 UI/ml is criteria of exclusion~* HBsAg negative but HBsAb positive~* HBsAg negative but HBcAb positive~* Patients HBsAg positive with HBV DNA \< 2000 UI/ml and HBsAg nega-tive but HBcAb positive will be eligible for the study only if they accept to receive prophylactic Lamivudine 100 mg/daily for all the period of treatment and at least for 12 months after the end of therapy. Treatment with ABT-199 should be stopped in case of hepatitis reactivation.~* Active HCV positive hepatitis~* If female, the patient is pregnant or breast-feeding.

- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- ARM1 - Venetoclax (ABT-199) (Type: EXPERIMENTAL): Venetoclax (ABT-199) will be administered orally at the dose of 800 mg once daily.~Response evaluation will be performed initially after 3 cycles from the beginning of treatment with ABT-199 and then every 3 cycles during the first 12 cycles, every 4 cycles from cycle 13 to 24; for those patients still on therapy after 24 cycles, the response evaluation, after this time, will be performed every 6 cycles.

Based on this trial design, predict the completion outcome and termination type (if applicable).

Answer: outcome: terminate
termination_type: lack of efficacy
