Recruitment & Eligibility

• Status: Authorised-recruitment may be ongoing or finished
• Sex: All
• Target Recruitment: 35

Inclusion Criteria

•Histologically documented diagnosis of BCL-2 positive PTCL-NOS, AITL, TFH as defined in the 2016 edition of the World Health Organization (WHO) classification. Only patients with percentage of BCL-2 positive tu-mor cells >= 25% in the relapse biopsy, if available, or otherwise in the ini-tial biopsy, will be included onto the study;
• Age >= 18 years
• Relapsed or refractory to at least one previous standard line of treatment
• Eastern Cooperative Oncology Group (ECOG) performance status (PS) <= 2
• At least one site of measurable nodal or extranodal disease at baseline >= 2.0 cm in the longest transverse diameter as determined by CT scan (MRI is allowed only if CT scan cannot be performed). Note: Patients with only bone marrow involvement are eligible
• Adequate hematological counts defined as follows:
- Absolute Neutrophil count (ANC) > 1.0 x 10^9/L unless due to bone marrow involvement by lymphoma
- Platelet count >= 50.000/mm^3 unless due to bone marrow involvement by lymphoma
• Adequate renal function defined as follows:
- Creatinine clearance >= 30 mL/min
• Adequate hepatic function per local laboratory reference range as follows:
- Aspartate transaminase (AST) and alanine transaminase (ALT) <= 3.0 x ULN
- Bilirubin <=1.5 x ULN (unless bilirubin rise is due to Gilbert’s syn-drome or of non-hepatic origin)
• Subject understands and voluntarily signs an informed consent form ap-proved by an Independent Ethics Committee (IEC)/Institutional Review Board (IRB), prior to the initiation of any screening or study-specific proce-dures
• Subject must be able to adhere to the study visit schedule and other pro-tocol requirements
•Subject must be able to swallow capsules or tablets
• Life expectancy >= 3 months
• Women must be:
- postmenopausal for at least 1 year (must not have had a natural menses for at least 12 months)
- surgically sterile (have had a hysterectomy or bilateral oophorectomy, tubal ligation, or otherwise be incapable of pregnancy),
- completely abstinent (periodic abstinence from intercourse is not permit-ted) or if sexually active, be practicing a highly effective method of birth control (e.g., prescription oral contraceptives, contraceptive injections, contraceptive patch, intrauterine device, double barrier method (e.g.: condoms, diaphragm, or cervical cap, with spermicidal foam, cream, or gel, male partner sterilization) as local regulations permit, before entry, and must agree to continue to use the same method of contraception throughout the study. They must also be prepared to continue birth con-trol measures for at least 1 month after terminating treatment.
- women of childbearing potential must have a negative pregnancy test at screening
• Men must agree to use an acceptable method of contraception (fort them-selves 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 femal

Exclusion Criteria

•Histological diagnosis different from BCL-2 positive PTCL-NOS, AITL, and TFH

• 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.

- 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 treat-ment and at least for 12 months after the end of therapy. Treatment with ABT-199 should be stopped in case of hepatitis reactivation.
