Efficacy and Safety of Oral Azacitidine (CC-486) Compared to Investigator's Choice Therapy in Patients With Relapsed or Refractory Angioimmunoblastic T Cell Lymphoma

Randomized Phase 3 Study Evaluation the Efficacy and Safety of Oral Azacitidine(CC-486) Compared to Investigator's Choice Therapy in Patients With Relapsed or Refractory Angioimmunoblastic T Cell Lymphoma

This study is a multicentric, open-label, randomized phase 3 trial. The study will be conducted in select countries in Europe and South Korea sponsored by LYSARC and in Japan sponsored by Celgene. There will be a combined enrollment target of 86 randomized patients, with approximately 14 randomized patients from Japan.

The enrollment to the randomized study will start at European sites in parallel to a safety run-in part in Japan. A safety run-in will be conducted to confirm the tolerability of oral azacitidine at doses of 100 mg and 200 mg QD in Asian patients. Once oral azacitidine at 200 mg QD is confirmed as tolerable, Asian patients from Japan and South Korea will start to be randomized into the main study. Additional patients (non-randomized) are anticipated to enroll to the safety run-in.

• Accepts Healthy Volunteers: No

Description

Inclusion Criteria:

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 WHO classification based on a surgical lymph node biopsy or needle core 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. 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:

   • ANC ≥ 1,5 x 109/L (≥ 1 x 109/L if 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 6 months 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, symptomthermal, 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 6 months 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).

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Progression Free Survival (PFS) Based on Local Assessment	PFS is defined as the time from randomization into the study to the first observation of documented disease progression (local assessment using Lugano Response Criteria 2014) or death due to any cause, whichever occurs first. If a participant has not progressed or died, PFS will be censored at the time of last visit with adequate assessment. C2 censoring rules were used per US FDA guidance 2015. Progression will be determined as per Response criteria for lymphoma: Lugano classification.	From randomization up to documented disease progression or death, whichever occurs first (up to approximately 15 months)

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Survival (OS)	Overall survival is defined as the time from the date of randomization to the date of death from any cause. OS was censored at the last date that the participant was known to be alive.	From randomization up to the date of death or date last known alive (up to approximately 27 months)
Progression Free Survival (PFS) Based on IRC Assessment	PFS based on Independant Review Committee (IRC) is defined as the time from randomization into the study to the first observation of documented disease progression (reviewed assessment by IRC using Lugano Response Criteria 2014) or death due to any cause. If a patient has not progressed or died, PFS will be censored at the time of last visit with adequate assessment per FDA's guidance 2015 Table C2. Progression will be determined as per Response criteria for lymphoma: Lugano classification.	From randomization up to documented disease progression or death, whichever occurs first (up to approximately 37 months)
Overall Response Rates (ORR)	Overall response rates are the percentage of complete response (CR) and partial response (PR) per local assessment. Assessment of response will be based on Lugano Response Criteria 2014 for the radiologic response (CT based), the metabolic response (PET-CT based) and the best response between radiologic and metabolic response. Measurements occurred after Cycle 3, after Cycle 6, and at permanent treatment discontinuation. PR is defined as Score 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size and ≥ 50% decrease in SPD of up to 6 target measurable nodes and extranodal sites. CR is defined as target nodes/nodal masses regressed to ≤ 1.5 cm in LDi, no extralymphatic sites of disease, and Score 1, 2, or 3 with or without a residual mass on the 5 Point Scale. The Lugano 5-point scale is 1, no uptake above background; 2, uptake mediastinum; 3, uptake mediastinum but liver; 4, uptake moderately liver; 5, uptake markedly higher than liver and/or new lesions.	Response rate will be measured after Cycle 3, after Cycle 6 (up to approximately 5.5 months)
Complete Response Rate (CRR)	Complete response rate is the percentage of CR (complete metabolic response or CT-based CR) per local assessment before receiving any subsequent anti-lymphoma therapy. Assessment will be based on Lugano Response Criteria 2014 for the radiologic response (CT based), the metabolic response (PET-CT based) and best response between radiologic and metabolic response. Measurements occurred after Cycle 3, Cycle 6, and treatment discontinuation. PR is defined as Score 4 or 5 with reduced uptake compared with baseline and residual mass(es) of any size and ≥ 50% decrease in SPD of up to 6 target measurable nodes and extranodal sites. CR is defined as target nodes/nodal masses regressed to ≤ 1.5 cm in LDi, no extralymphatic sites of disease, and Score 1, 2, or 3 with or without a residual mass. The Lugano 5-point scale is 1, no uptake above background; 2, uptake mediastinum; 3, uptake mediastinum but liver; 4, uptake moderately liver; 5, uptake markedly higher than liver and/or new lesions.	Response rate will be measured after Cycle 3, after Cycle 6 (up to approximately 5.5 months)
Duration of Response (DOR)	Duration of response is defined as the time from attainment of complete response (CR) or partial response (PR) per local assessment to the date of first documented disease progression, relapse (local assessment) or death from any cause. Participants alive and free of progression will be censored at their last visit with adequate assessment.CR: complete metabolic response or computed tomography (CT)-based CR; PR: partial metabolic response or CT-based PR before subsequent anti-lymphoma therapy.	From randomization to the date of first documented disease progression, relapse (local assessment) or death from any cause (up to approximately 27 months)
Time to Response (TTR)	Time to response is defined as the time from randomization to the date of attainment of complete response (CR) or partial response (PR) per local assessment until end of treatment. If a participant is not responder, time to response will be censored at the time of last visit with adequate assessment. CR: complete metabolic response or computed tomography (CT)-based CR; PR: partial metabolic response or CT-based PR before subsequent anti-lymphoma therapy.	From randomization to the date of attainment of complete response (CR) or partial response (PR) until end of treatment (up to approximately 37 months)
Progression Free Survival 2 (PFS2) on Local Assessment	PFS2 based on local assessment is defined as the time from randomization to objective tumor progression on next-line treatment or death from any cause. Participants without next-line therapy who did not die and participants who did not relapse or not die after next-line therapy will be censored at the last adequate tumor assessment date.	From randomization to objective tumor progression on next-line treatment or death from any cause (up to approximately 27 months)
Mean Change in Minimal Important Differences (MIDs) of the EORTC QLQ-C30 Health-related Quality-of-Life Domain Scores	The minimal important difference (MID) is the size of difference in Quality-of-Life score that is considered relevant (i.e. warranting a change in treatment or examinations). The European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire-Core 30 (QLQC30) subscale values are the lower threshold for MID over time, based on within-group mean change. QLQ-C30 has 5 functional scales (physical, role, emotional, cognitive, social), 3 symptom scales (fatigue, nausea/vomiting, pain), a global health status / quality of life (QoL) scale, and 6 single items (dyspnea, insomnia, appetite loss, constipation, diarrhea, financial difficulties). Each scale was scored on a range from 0 to 100. Higher scores represent a higher response level. Note that a high score for global health status or for a functional scale represents a high or healthy level of functioning, but a high score for a symptom scale/item represents a high level of symptomatology/problems.	At baseline and on Day 1 of each cycle up to treatment discontinuation (up to approximately 27 months)
