| Eligibility |
Inclusion Criteria:
Patients must satisfy all following criteria to be enrolled in the study::
1. Patient is = 18 years of age at the time of signing the informed consent form (ICF).
2. Patient must understand and voluntarily sign an ICF prior to any study-specific
assessments/procedures being conducted.
3. Patient is willing and able to adhere to the study visit schedule and other protocol
requirements
4. Patient had local diagnosed peripheral T cell lymphoma (PTCL) with T-follicular helper
(TFH) phenotype according to the criteria of the latest World Health Organization
(WHO) classification based on a surgical lymph node biopsy including any one of
- Angioimmunoblastic T cell lymphoma (AITL)
- Follicular T cell lymphoma
- Nodal peripheral T-cell lymphoma with TFH phenotype There should be a documented
expression of minimum two TFH markers among this panel of markers : CD10, CXCL13,
PD1, ICOS and BCL6 by the tumoral cells by immunohistochemistry. Biopsy at
relapse or progression is not mandatory, but highly encouraged on a surgical or
needle core biopsy, and diagnostic tissue should be available for central
pathology review and for ancillary molecular studies.
Local pathology report should be reviewed by the sponsor's medical monitor prior to
enrollment.
5. Eastern Cooperative Oncology Group (ECOG) performance status 0 to 3
6. Relapsed (after partial or complete response) or refractory AITL after at least one
line of systemic therapy (there is no mandatory resting period after the previous
treatment as long as the biochemistry and hematology labs meet the inclusion criteria
as below.)
7. Meet the following lab criteria:
- Absolute Neutrophil Count (ANC) = 1,5 x 109/L (= 1 x 109/L if bone marrow (BM)
involvement by lymphoma)
- Platelet = 75 x 109/L (= 50 x 109/L if BM involvement by lymphoma)
- Hemoglobin = 8 g/dL.
8. Anticipated life expectancy at least 3 months
9. At least one measurable lesion on CT that is greater than 1.5 cm in the longest
diameter for nodal lesions and greater than 1.0 cm in the longest diameter for
extranodal lesions. The lesion must be measurable in two perpendicular dimensions.
Patients with only cutaneous disease will be excluded.
10. Female patient of childbearing potential (FCBP) may participate, providing she meets
the following conditions:
Have two negative pregnancy tests as verified by the investigator prior to starting
study treatment: serum pregnancy test at Screening and negative serum or urine
pregnancy test (investigator's discretion) within 72 hours prior to starting treatment
with study treatment (Cycle 1 Day 1). She must agree to ongoing pregnancy testing
during the study (before beginning each subsequent cycle of treatment), and 28 days
after the last study drug administration. This applies even if the patient practices
complete abstinence from heterosexual contact.
Agrees to practice true abstinence (which must be reviewed monthly and source
documented) or agrees to the use of highly effective methods of contraception from 28
days prior to starting study treatment, and must agree to continue using such
precautions during study treatment (including dose interruptions) and for up to 90
days after the last study drug administration. True abstinence is acceptable when this
is in line with the preferred and usual lifestyle of the patient. Periodic abstinence
(eg, calendar, ovulation, symptom-thermal, post ovulation methods) and withdrawal are
not acceptable methods of contraception. Cessation of contraception after this point
should be discussed with a responsible physician.
Agrees to abstain from breastfeeding during study participation and for at least 90
days after the last study drug administration.
A female of childbearing potential (FCBP) is a female who: 1) has achieved menarche at
some point, 2) has not undergone a hysterectomy or bilateral oophorectomy or 3) has
not been naturally postmenopausal (amenorrhea following cancer therapy does not rule
out childbearing potential) for at least 24 consecutive months (i.e., has had menses
at any time during the preceding 24 consecutive months).
11. Male patient must either practice true abstinence from heterosexual contact (which
must be reviewed on a monthly basis and source documented) or agrees to avoid
fathering a child, to use highly effective methods of contraception, male condom plus
spermicide during sexual contact with a pregnant female or a female of childbearing
potential (even if he has undergone a successful vasectomy), from starting dose of
drug (cycle 1 Day 1), including dose interruptions through 90 days after receipt of
the last study drug administration. Furthermore, male patient must agree to not give
semen or sperm during study drug therapy and for a period of 1 year after end of study
drug therapy.
12. For EU countries, patient covered by a social security system
Exclusion Criteria:
Presence of any of the following will exclude a patient from enrollment:
1. Clinical evidence of central nervous system involvement by lymphoma. Patients with
suspicion of central nervous system (CNS) involvement must undergo neurologic
evaluation and CT/MRI of head and lumbar puncture to exclude CNS disease.
2. Any significant medical conditions, laboratory abnormality or psychiatric illness
likely to interfere with participation in this clinical study (according to the
investigator's decision)
3. Uncontrolled systemic fungal, bacterial, or viral infection (defined as ongoing
signs/symptoms related to the infection without improvement despite appropriate
antibiotics, antiviral therapy, and/or other treatment)
4. Known Human Immunodeficiency Virus (HIV) or Hepatitis C Virus (HCV) infection, or
evidence of positive HTLV1 serology or of active Hepatitis B (HB) Virus (HBV)
infection defined as:
- HB s Ag positive
- HB s Ag negative, anti-HB s antibody positive and/or anti-HB c antibody positive
with detectable viral DNA
5. Impaired renal function (MDRD formula or Cockcroft-Gault Creatinine Clearance < 30
ml/min) or impaired liver function tests (Serum total bilirubin level > 2.0 mg/dl [34
µmol/L] (except in case of Gilbert's Syndrome, or documented liver or pancreatic
involvement by lymphoma), Serum transaminases (AST or ALT) > 3 upper normal limits)
unless they are related to the lymphoma.
6. Active malignancy other than the one treated in this research. Prior history of
malignancies, other than low risk MDS or chronic myelomonocytic leukemia (CMML) (with
less than 5% blasts in bone marrow), unless the patient has been free of the disease

allowed:
1. Basal or squamous cell carcinoma of the skin
2. Carcinoma in situ of the cervix
3. Carcinoma in situ of the breast
4. Incidental histologic finding of prostate cancer (T1a or T1b) using the

endoscopic submucosal dissection
7. Treatment with any investigational drug within 5 half-lives before planned first cycle
of study treatment and during the study. Ongoing medically significant adverse events
from previous treatment, regardless of the time period.
8. Prior exposure to azacitidine and/ or any other demethylating agent (eg, decitabine)
9. Prior exposure to planned study treatment investigator's choice therapy (eg, prior
exposure to gemcitabine is an exclusion if gemcitabine is the investigator's choice
therapy prior to randomization)
10. Concurrent use of corticosteroids unless the patient is on a stable or decreasing dose
for = 1 week prior to informed consent form signature
