Detailed Description

Background:

T-cell lymphoma is an aggressive rare subset of Non-Hodgkin lymphoma (NHL) comprising several different subtypes of disease within this group. No standard first-line treatment exists for T-cell lymphoma as published series are small, with heterogeneous populations and often retrospective.

Protocol Synopsis, Study Period: 5 years

Objectives:

Primary:

• To compare the complete response rate of GEM-P with CHOP chemotherapy in the first line treatment of patients with T-Cell Lymphoma.

Secondary:

To investigate, between both arms:

• Rate of metabolic complete response
• Toxicity of treatment
• Overall survival (OS)
• Progression Free Survival (PFS)

Exploratory:

• Investigate impact of International Prognostic Index (IPI) on the outcomes response rate, PFS and OS

Study Design:

A randomised multi-centre open-label phase II study

Indication: Previously untreated T-Cell lymphoma No of Participants: 186 (93 patients in each arm)

Main Eligibility Criteria:

• Histologically proven T-cell lymphoma of the following subtypes:
• Peripheral T-cell lymphoma NOS
• Systemic Anaplastic large cell lymphoma (ALCL) Anaplastic lymphoma kinase (ALK) negative cases only
• Angioimmunoblastic T-cell lymphoma
• Hepatosplenic gamma/ delta T-cell lymphoma
• Enteropathy-associated T-cell lymphoma
• Bulky Stage I, Stage II, III or IV
• No prior chemotherapy regimen
• Patients aged 18 years or over.
• WHO performance status 0,1 or 2
• Adequate organ function:
• No Central Nervous System(CNS) or leptomeningeal involvement with lymphoma
• No treatment for lymphoma within 4 weeks of commencing trial therapy
• No known HIV, active Hepatitis B or C infection

Treatment:

CHOP: cyclophosphamide, doxorubicin, vincristine, prednisolone every 21 days. GEM-P: gemcitabine, methylprednisolone, cisplatin every 28 days.

Assessment Schedule:

• Patients will be reviewed at baseline and prior to each scheduled dose of treatment for toxicity
• Radiological tumour assessment will be done with CT scan after every 2 cycles in Arm A and after cycle 1, 3 and 4 in Arm B
• PET/CT scan will be performed at baseline and upon completion of treatment..
• Follow up after completion of treatment will be 3, 6, 9, 12, 18, 24 months then annually for 5 years in total. CT scan will be performed at 3 & 12 months.
• Following disease progression patients will be followed for survival every 3 months until death

• Study Type: Interventional
• Enrollment (Actual): 87
• Phase: Phase 2

Description

Inclusion Criteria:

Previously untreated, histologically proven T-cell Lymphoma (any of the following):

• Peripheral T-cell lymphoma Not Otherwise Specified (PTCL NOS)
• Systemic Anaplastic large cell lymphoma (ALCL) ALK negative cases only

  • Patient is male or female, and ≥18 years of age on the day of signing informed consent.
  • WHO performance status 0, 1 or 2.
  • Cross sectional imaging from a baseline contrast enhanced CT should show at least one measurable disease site that is at least 2 cm in longest diameter and measurable in two perpendicular dimensions with or without corresponding Fluorodeoxyglucose(FDG) avid lesions.
  • Adequate cardiac function; formal assessment of left ventricular ejection fraction is only required if clinically indicated (a baseline echocardiogram should be done for patients with either hypertension, age > 60 years or history of cardiac disease)
  • Adequate bone marrow function: absolute neutrophil count (ANC) ≥1.0x109/l; white blood cell count ≥ 3x109/l; platelets ≥ 100x109/l; haemoglobin (Hb) ≥ 9g/dl (can be post-transfusion), unless deemed disease related
  • Adequate renal function: calculated creatinine clearance ≥50ml/minute.
  • Adequate liver function: serum bilirubin ≤1.5x Upper limit of normal (ULN); Alanine transaminase/Aspartate transaminase (ALT/AST) ≤2.5x ULN; ALP ≤3x ULN (in the absence of liver metastases). If liver metastases are present, ALT, AST or Alkaline phosphatase (ALP) ≤5x ULN are permitted. Isolated hyperbilirubinaemia due to Gilbert's disease is acceptable
  • Female patient of childbearing potential must have a negative serum or urine β-human chorionic gonadotropin(hCG)pregnancy test at baseline.
  • Written informed consent must be obtained prior to start of study treatments. Scans and bone marrow biopsies performed within 4 weeks of commencement of therapy will be acceptable provided they have been performed according to study requirements.
