Study information
Scientific title
STI571 Prospective International RandomIsed Trial 2: A phase III, prospective randomised comparison of imatinib (STI571, Glivec®/ Gleevec®) 400 mg daily versus dasatinib (Sprycel®) 100 mg daily in patients with newly-diagnosed chronic phase chronic myeloid leukaemia
Acronym
SPIRIT 2
Study hypothesis
To compare 5-year Event Free Survival (EFS) between the treatment arms. The study is powered to demonstrate superiority of the dasatinib arm over the imatinib arm.
Ethics approval

Condition
Newly diagnosed, chronic-phase, chronic myeloid leukaemia
Intervention
Arm 1: Imatinib (oral) 400 mg daily, to be taken for a minimum of 5 years

Phase
Phase III
Drug names
STI571 (Glivec®/ Gleevec®) and dasatinib (Sprycel®).
Primary outcome measure
Event -free survival at 5 years
Secondary outcome measures
1. To compare the rate of complete cytogenetic response after 2 years
2. To compare the treatment failure rates (TFR) at 5 years
3. To compare the rates of complete haematologic response (CHR). Duration of follow-up: 60 months
4. To compare the level of 'molecular' response (BCR-ABL/ABL ratio by real time polymerase chain reaction [PCR]). Duration of follow-up: 60 months
5. To compare the tolerability between the regimens. This will in part be incorporated into the treatment failure assessment. Duration of follow-up: 60 months
6. To assess quality of life by the EQ-5D and the Functional Assessment of Cancer Treatment-Biological Response Modifier (FACT-BRM) questionnaires. Timepoints of assessment: at screening and then Months 1, 2, 3, 6, 12, 24, 36, 48, 60
7. To assess the broad comparative costs between the regimens
8. To compare overall survival at 2 and 5 years

Participant exclusion criteria
1. Patients with Ph-negative, BCR-ABL-positive disease are not eligible for the study
2. Any prior treatment for CML with: any tyrosine kinase inhibitor (e.g., imatinib, dasatinib, nilotinib); busulphan; interferon-alpha; homoharringtonine; cytosine arabinoside; any other investigational agents (hydroxycarbamide and anagrelide are the only drugs permitted). NB: Patients will be ineligible for the study if they have received any prior therapy with interferon-alpha or imatinib. No exceptions.
3. Patients who received prior chemotherapy, including regimens used in peripheral blood progenitor cells (PBPCs) mobilisation for haematopoietic progenitor-cell transplantation (It is allowable to collect unmobilised PBPCs at diagnosis)
4. Patient who have had any form of prior haemopoietic stem cell transplant, either autograft or allograft
5. Patients with an Eastern Cooperative Oncology Group (ECOG) Performance Status Score >= 3
6. Patients with serum bilirubin, aspartate aminotransferase (SGOT/AST), alanine aminotransferase (SGPT/ALT), or creatinine concentrations > 2.0 x the institutional upper limit of the normal range
(IULN)
7. Patients with International normalised ratio (INR) or partial thromboplastin time (PTT) >1.5 x IULN, with the exception of patients on treatment with oral anticoagulants
8. Patients with uncontrolled medical disease such as diabetes mellitus, thyroid dysfunction, neuropsychiatric disorders, infection, angina, or Grade 3/4 cardiac problems as defined by the New York Heart Association Criteria
9. Patients with known positivity for human immunodeficiency virus (HIV); baseline testing for HIV is not required
10. Patients who have undergone major surgery within 4 weeks of Study Day 1, or who have not recovered from prior major surgery
11. Patients who are:
11.1 Pregnant
11.2. Breast feeding
11.3. Of childbearing potential without a negative pregnancy test prior to Study Day 1
11.4. Male or female of childbearing potential unwilling to use barrier contraceptive (Amenorrhoeic for at least 12 months to be considered of non-childbearing potential)
12. Patients with a history of another malignancy either currently or within the past five years, with the exception of basal cell skin carcinoma or cervical carcinoma in situ
13. Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable
