Study title
KISS: Kinase Inhibition With Sprycel Start up
Scientific title
KISS Study: A Phase II Study of Dasatinib Followed by Imatinib in Newly Diagnosed, Previously Untreated Patients With Chronic Phase CML (ClinicalTrials.gov NCT03193281)
Indication and most important inclusion criteria
This study includes male or female patients who:
- are at least 18 years old
- have an Eastern Co-Operative Oncology Group (ECOG) status of 0, 1 or 2
- have been diagnosed with chronic myeloid leukemia in chronic phase within 3 months of enrolment
- have cytogenetic or molecular confirmation of Philadelphia chromosome (Ph+) or variants of (9;22) translocations
Short description of intervention
This study will assess the efficacy and safety of a treatment plan for patients with newly diagnosed CML-CP. In the first study stage, patients will be given dasatinib (Sprycel) to more rapidly induce a molecular response (MR3.0). At 13 months, patients will be switched to imatinib to maintain CML in that remission.
Patients who do not achieve confirmed MR3.0 at 13 months will not be eligible to switch to imatinib treatment and will continue on dasatinib treatment.

Chronic Myeloid Leukemia
also called: Chronic Myelogeneous Leukemia
A chronic disease of the blood and bone marrow that results from a transformation of a stem cell.
Philadelphia chromosome
A certain change in chromosomes (on chromosome 22) found in 95% of patients who have CML. The Philadelphia chromosome results from a mutation that involves the fusion of parts of chromosome 9 and chromosome 22 (the bcr-abl fusion gene)
Inclusion criteria
Inlusion criteria define which subjects may participate in a clinical study. Study subjects must fulfill all inclusion criteria (e.g. with regard to sex, age, previous diseases). This ensures a uniform composition of the study population and minimizes the risk of influences that distort the study results.
Chronic phase
The earliest phase of CML development.
Chromosome
A chromosome is a structure of DNA that carries the genetic makeup in the nucleus of the cell. Chromosomes contain giant chain molecules of DNA, coiled and folded as aggregates with specific proteins. Chromosomes ensure that during cell division the hereditary information is evenly distributed to the daughter cells. Normal human body cells have 46 chromosomes. Cancer cells can have a different number and/or structure of chromosomes.
Indication
In medicine, a reason to use a certain diagnostic test, therapeutic procedure or medication. The opposite of indication is contraindication.
Dasatinib
Trade name: Sprycel, development name: BMS-354825, inhibits BCR-ABL and SRC tyrosine kinases. Authorized for marketing in the EU since 2006 for the treatment of CML and Ph+ALL.
Other names: BMS-354825|BMS354825|Sprycel
Imatinib
Imatinib, trade name Glivec/Gleevec, development name STI-571, a first-generation BCR-ABL tyrosine kinase inhibition. Authorized for marketing since 2002 for the treatment of CML and Ph-positive ALL.
Other names: Gleevec|Glivec
Chronic
Long-lasting, slowly developping
ECOG
Eastern Cooperative Oncology Group Index to classify the quality of life of cancer patients on a scale ranging from 0 (fully active, able to carry on all predisease activities without restriction) to 5 (death).
Also often referred to as ECOG performance status.
Gene
A unit of information present as DNA; a gene usually contains the blueprint for a protein.
CML
Chronic Myeloid Leukemia, also called Chronic Myelogenous Leukemia
A chronic disease of the blood and bone marrow that results from a transformation of a stem cell.
Ph+
Abbreviation for "Philadelphia-Chromosome-positive", meaning the presence of a certain change in chromosomes (on chromosome 22) found in 95% of patients who have CML. The Philadelphia chromosome results from a mutation that involves the fusion of parts of chromosome 9 and chromosome 22 (the bcr-abl fusion gene).
CHR
Abbreviation for Complete Hematologic Response. The blood cell count has returned to normal, and tests don’t show any immature white blood cells. Also, the spleen has returned to a normal size if it was enlarged.
