Scientific titleA phase II study of GCS-100 in combination with chemo-immunotherapy in relapsed or refractory diffuse large B-cell lymphoma
Study objectivesThe primary objective of this study is to assess the efficacy of GCS-100 with rituximab, ifosfomide, mesna, carboplatin and etoposide (R-ICE) chemotherapy in subjects with relapsed or refractory diffuse large B-cell lymphoma (DLBCL). The secondary objective is to determine the safety of GCS-100 in conjunction with cytotoxic chemotherapy.
Ethics approval(s)The study was approved by the London Research Ethics Committee (REC) of Northwick Park Hospital on the 6th October 2008 (ref: 08/H0718/57)
Health condition(s) or problem(s) studiedRelapsed or refractory diffuse large B-cell lymphoma (DLBCL)
InterventionThis is a single-arm trial of GCS-100 with R-ICE chemotherapy administered in 21-day cycles (a maximum of four chemotherapy cycles per participant). Each 21-day treatment cycle consists of the following:

Days 1 - 5: GCS-100 160 mg/m^2/day intravenously (IV) over 1 hour.

Dosing with GCS-100 will be followed at least 1 hour later by:
Day 1: rituximab 375 mg/m^2 IV
Days 2: carboplatin dose area under the curve (AUC) = 5 mg/mL x min (maximum 800 mg) IV
Days 2 - 4: ifosfamide 1667 mg/m^2 IV
Days 2 - 4: mesna 1667 mg/m^2 IV or oral
Days 2 - 4: etoposide 100 mg/m^2 IV

Pharmaceutical study type(s)
PhasePhase II
Drug / device / biological / vaccine name(s)GCS-100, rituximab, ifosfomide, mesna, carboplatin, etoposide
Primary outcome measure1. Response: overall response rate, defined as the sum of the number of CR rate and PR rate. CR and PR will be defined according to the International Harmonisation Project for Lymphoma criteria.
2. Imaging: CT scans will be obtained at baseline and every two cycles to assess for response. They will be evaluated according to the International Harmonisation Project for Lymphoma.

Total duration of follow-up for the primary and secondary outcome measures: 16 weeks.
Secondary outcome measuresTo determine the safety of GCS-100 in conjunction with cytotoxic chemotherapy by collecting adverse event data and monitoring blood parameters, etc. Total duration of follow-up for the primary and secondary outcome measures: 16 weeks.

Key exclusion criteria1. Subject has received high-dose chemotherapy with haematopoietic stem cell support or allogeneic stem cell transplantation (SCT)
3. Subject has rapidly progressive lymphoma or lymphoma threatening organ function
4. Subjects with primary or secondary central nervous system lymphoma
5. Subjects who have had treatment with an experimental (unlicensed) drug within 3 weeks prior to treatment with GCS-100
6. Subject has not recovered from all toxic effects of previous chemotherapy, radiation therapy, biologic therapy, and/or experimental therapy
7. Subject has a known history of human immunodeficiency virus-related lymphoma, active hepatitis C, active hepatitis B, or prior history of infection with hepatitis B (HBcAb positive)
8. Subject has a clinically relevant active infection and/or a serious co-morbid medical condition such as recent myocardial infarction (within the last 6 months and no electrocardiographic evidence of acute ischaemia or new conduction system abnormalities), unstable angina, difficult-to-control congestive heart failure, uncontrolled hypertension, difficult-to-control cardiac arrhythmias, chronic obstructive or chronic restrictive pulmonary disease, and/or cirrhosis.
