Clinical Trial Summary

This study will be a multicenter Phase IIIb open-label, three-cohort study of asciminib in patients with CML-CP without T315I mutation who have had at least 2 prior TKIs and CML-CP harboring the T315I mutation with at least 1 prior TKI


Description:

This trial consists of three periods: screening and baseline for up to 21 days, active treatment for up to 72 weeks and a safety follow up period for 30 days. One hundred and fifteen (115) patients with chronic myeloid leukemia in chronic phase (CML-CP) without T315I mutation who have had at least 2 prior Tyrosine Kinase Inhibitors (TKIs) and CML-CP with the T315I mutation with at least 1 prior TKI will be considered for the current study Informed consent will be obtained before any procedures are performed for the study including eligibility assessments. The results of the real time quantitative polymerase chain reaction (RQ-PCR) must be available prior to randomization and first dose of study treatment. Patients with CML-CP without T315I mutation will be randomly assigned to either cohort A or B. Patients with the T315I mutation will be enrolled in cohort C. During treatment period asciminib will be taken orally: Cohort A will be administered 40 mg twice a day, Cohort B will be administered 80 mg once a day and Cohort C will be administered 200 mg twice a day. The patients will be treated up to end of study treatment period defined as up to 72 weeks after the last patient receives the first dose. Patients may be discontinued from treatment with the study drug at any time due to unacceptable toxicity, disease progression and/or at the discretion of the investigator or the patient.

Previous treatment with or known/ suspected hypersensitivity to asciminib or any of its excipients. 10. Participation in a prior investigational study within 30 days prior to randomization or within 5 half-lives of the investigational product, whichever is longer 11. Pregnant or nursing (lactating) women 12. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception. 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. 13. Sexually active males unwilling to use a condom during intercourse while taking study treatment and for 3 days after stopping study (only for patients treated with asciminib). A condom is required for all sexually active male participants on asciminib treatment to prevent them from fathering a child AND to prevent delivery of study treatment via seminal fluid to their partner. In addition, these male participants must not donate sperm for the time period specified above. 14. If a patient is presenting with symptoms suggestive of possible COVID-19 infection, we advise ruling it out by appropriate testing recommended by health authorities. - Nucleic acid amplification tests for viral RNA (polymerase chain reaction), in order to measure current infection with SARS-CoV-2 - Antigen tests for rapid detection of SARS-CoV-2 - Antibody (serology) tests to detect the presence of antibodies to SARS-CoV-2
