Eligibility
Key inclusion criteria
Male or female patients with a diagnosis of CML-CP = 18 years of age

Patients must meet all of the following laboratory values at the screening visit:

- < 15% blasts in peripheral blood and bone marrow

- < 30% blasts plus promyelocytes in peripheral blood and bone marrow

- < 20% basophils in the peripheral blood

- = 50 x 109/L (= 50,000/mm3) platelets

- Transient prior therapy related thrombocytopenia (< 50,000/mm3 for = 30 days prior to
screening) is acceptable

- No evidence of extramedullary leukemic involvement, with the exception of
hepatosplenomegaly

BCR-ABL1 ratio > 0.1% IS according to central laboratory at the screening examination for
patients intolerant to the most recent TKI therapy

Prior treatment with a minimum of 2 prior ATP-binding site TKIs (i.e. imatinib, nilotinib,
dasatinib, radotinib or ponatinib)

Failure (adapted from the 2013 ELN Guidelines Bacarrani 2013) or intolerance to the most
recent TKI therapy at the time of screening

- Failure is defined for CML-CP patients (CP at the time of initiation of last therapy)
as follows. Patients must meet at least 1 of the following criteria.

- Three months after the initiation of therapy: No CHR or > 95% Ph+ metaphases

- Six months after the initiation of therapy: BCR-ABL1 ratio > 10% IS and/or > 65% Ph+
metaphases

- Twelve months after initiation of therapy: BCR-ABL1 ratio > 10% IS and/or > 35% Ph+
metaphases

- At any time after the initiation of therapy, loss of CHR, CCyR or PCyR

- At any time after the initiation of therapy, the development of new BCR-ABL1 mutations
which potentially cause resistance to study treatment

- At any time after the initiation of therapy, confirmed loss of MMR in 2 consecutive
tests, of which one must have a BCR-ABL1 ratio = 1% IS

- At any time after the initiation of therapy, new clonal chromosome abnormalities in
Ph+ cells: CCA/Ph+

- Intolerance is defined as:

- Non-hematologic intolerance: Patients with grade 3 or 4 toxicity while on therapy, or
with persistent grade 2 toxicity, unresponsive to optimal management, including dose
adjustments (unless dose reduction is not considered in the best interest of the
patient if response is already suboptimal)

- Hematologic intolerance: Patients with grade 3 or 4 toxicity (absolute neutrophil
count [ANC] or platelets) while on therapy that is recurrent after dose reduction to
the lowest doses recommended by manufacturer

- Women of child-bearing potential, defined as all women physiologically capable of
becoming pregnant, unless they are using highly effective methods of contraception
during dosing and for 3 days after last dose of ABL001 and one month after last dose
of bosutinib. Highly effective contraception methods include:

- Total abstinence (when this is in line with the preferred and usual lifestyle of the
subject. Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation
methods) and withdrawal are not acceptable methods of contraception

- Female sterilization (have had surgical bilateral oophorectomy (with or without
hysterectomy) total hysterectomy or bilateral tubal ligation at least six weeks before
taking study treatment). In case of oophorectomy alone, only when the reproductive
status of the woman has been confirmed by follow up hormone level assessment

- Male sterilization (at least 6 months prior to screening). The vasectomized male
partner should be the sole partner for that subject.

- Use of oral, injected or implanted hormonal methods of contraception or placement of
an intrauterine device (IUD) or intrauterine system (IUS) or other forms of hormonal
contraception that have comparable efficacy (failure rate <1%), for example hormone
vaginal ring or transdermal hormone contraception.

- In case of use of oral contraception women should have been stable on the same pill
for a minimum of 3 months before taking study treatment.

- Women are considered post-menopausal and not of child bearing potential if they have
had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile
(e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral
oophorectomy (with or without hysterectomy), total hysterectomy or bilateral tubal
ligation at least six weeks before taking study medication. In the case of
oophorectomy alone, women are considered post-menopausal and not of child bearing
potential only when the reproductive status of the woman has been confirmed by follow
up hormone level assessment.

Summary
Brief summary
The purpose of this pivotal study was to compare the efficacy of asciminib (ABL001) with that
of bosutinib in the treatment of patients with CML-CP having previously been treated with a
minimum of two prior ATP-binding site TKIs.

Patients intolerant to the most recent TKI therapy must have had BCR-ABL1 ratio > 0.1% IS at
screening and patients failing their most recent TKI therapy must have met the definition of
treatment failure as per the 2013 European LeukemiaNet (ELN) recommendations.

Patients with documented treatment failure as per 2013 ELN recommendations while on bosutinib
treatment had the option to switch to asciminib treatment within 96 weeks after the last
patient has been randomized on study.
