Study information
Scientific title
A phase III, prospective randomised comparison of imatinib (STI571, Glivec/Gleevec) 400 mg daily versus imatinib 800 mg daily versus imatinib plus PEG interferon-alpha 2a (Pegasys) in patients with newly-diagnosed chronic phasechronic myeloid leukaemia
Acronym
SPIRIT
Study hypothesis
The only known curative therapy for Chronic Myeloid Leukaemia (CML) is allogeneic Stem Cell Transplantation (SCT) but the risks of this are considerable and it is only available to a minority of patients with CML. Imatinib (ST1571, Gleevec, Glivec) has produced remarkable results in the treatment of CML although data on long term survival are not available.
In light of recent evidence, National Institute for Clinical Excellence (NICE) have recommended imatinib as the standard of care for newly diagnosed CML patients (http://www.nice.org.uk/Docref.asp?d=89864). SPIRIT aims to establish whether combining imatinib with other drugs, or increasing the dose to 800 mg daily can improve survival when compared to imatinib 400 mg daily. This is a crucial long-term study attempting to improve the survival for patients with CML and to determine the optimal non-transplant therapy for CML.
Ethics approval
The London main REC gave a favourable opinion for the trial on the 20th August 2004 (ref: O4/MREC02/13). Each participating site has gained Site Specific Assessment (SSA) approval from their local ethics committee prior to patient recruitment at that site.

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 busulphan, interferon-alpha, imatinib, homoharringtonine, cytosine arabinoside, or any other investigational agents (hydroxyurea and anagrelide are the only drugs permitted)
N.B. patients will be ineligible for SPIRIT 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) mobilization for haematopoietic progenitor-cell transplantation. It is allowable to collect unmobilized PBPCs at diagnosis
4. Patients who have had any form of prior haemopoietic stem cell transplant, eitherautograft or allograft
5. Patients with an Eastern Cooperative Oncology Group (ECOG) Performance Status Score more than or equal to three
6. Patients with serum bilirubin, Serum Glutamic Oxaloacetic Transaminase (SGOT)/aspartate aminotransferase (AST), Serum Glutamic Pyruvic Transaminase (SGPT)/alanine aminotransferase (ALT), or creatinine concentrations more than 2.0 x the Institutional Upper Limit of the Normal range (IULN)
7. Patients with International Normalised Ratio (INR) or Partial Thromboplastin Time (PTT) more than 1.5 x IULN, with the exception of patients on treatment with oralanticoagulants
8. Patients with uncontrolled medical disease such as diabetes mellitus, thyroid dysfunction, neuropsychiatric disorders, infection, angina, or Grade three/four cardiac problems as defined by the New York Heart Association Criteria
9. Patients with a prior history of significant psychiatric illness, particularly depression
10. Patients with known positivity for Human Immunodeficiency Virus (HIV); baseline testing for HIV is not required
11. Patients who have undergone major surgery within four weeks of Study Day one, or who have not recovered from prior major surgery
12. Patients who are:
a. Pregnant
b. Breast feeding
c. Of childbearing potential without a negative pregnancy test prior to Study Day one
d. Male or female of childbearing potential unwilling to use barrier contraceptive precautions throughout the trial (postmenopausal women must be amenorrheic for at least 12 months to be considered of non-childbearing potential)
13. 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
14. Patients with a history of non-compliance to medical regimens or who are considered potentially unreliable
