A Dose Calibration Study Comparing IkT-001Pro to Imatinib Mesylate 400mg

Completed · Phase 1

Conditions studied: CML

In brief

This study investigates the safety, tolerability and dose equivalence of drug IkT-001Pro in healthy volunteers (18 to 55 years old) in comparison to imatinib mesylate. This study is designed in 3 parts. Part A consists of 3 cohorts. In cohort 1 healthy participants will take a single, oral dose of 400mg IkT-001Pro then will be followed by a single dose of 400mg Imatinib mesylate after a 7-day washout. Cohort 2 and 3 will follow the same structure as cohort 1 with a different Ikt-001Pro dose. Part B will be chosen using Part A data by statistical procedures. Part B will enroll 32 subjects to demonstrate the bioequivalence of IkT-001Pro (the 'Test') to 400 mg imatinib delivered as imatinib mesylase (the 'Reference'). Part C (Dose Equivalence at 600 mg): Part C will enroll up to eight (8) subjects to demonstrate bioequivalence of imatinib delivered as 800 mg IkT-001Pro (the 'Test') to 600 mg imatinib delivered as imatinib mesylate ('the Reference')

You may qualify if…

Subject must have all questions about the study answered and must have signed the informed consent document before any study-specific procedures are performed.
Healthy ambulatory male and female subjects > 18 to < 55 years of age at the Screening visit, with no history or evidence of clinically relevant medical disorders as determined by the Investigator in consultation with the Sponsor.
Bodyweight > 50 kg and body mass index (BMI) > 18.0 and < 32.0 kg/m2 at the screening visit.
Physical examination, clinical laboratory values, vital signs, and electrocardiogram (ECG) data. Vital signs and clinical laboratory values must be within the normal range and or deemed not clinically significant by the PI and ECG tracings must be normal at baseline and/or deemed not clinically significant by the PI.
Female subjects must be postmenopausal, permanently sterile (bilateral tubal occlusion), or of childbearing potential with a negative pregnancy test, non-breastfeeding, and using two highly effective methods of birth control prior to screening and through completion of the last follow-up visit. If a subject discontinues early after receiving a dose of study drug, she must continue this method of birth control for at least 7 days following the last dose of the study drug. Highly effective methods of birth control are defined as follows: hormonal (ie, established use of oral, implantable, injectable, or transdermal hormonal methods of contraception); placement of an intrauterine device; placement of an intrauterine system; and mechanical /barrier method of contraception (ie, condom or occlusive cap [diaphragm or cervical/vault cap] in conjunction with spermicide [foam, gel, film, cream or suppository]).
Male subjects must agree to practice an acceptable method of highly effective birth control from the Screening visit, while on study and for 7 days after receiving the last dose of study drug. Highly effective methods of birth control include sexual abstinence; vasectomy; or a condom with spermicide (men) in combination with their partner's highly effective method.
Males must be willing to abstain from sperm donation from the screening visit, while on study and through 30 days after receiving the last dose of study drug.

You may not qualify if…

Any subject with previous exposure to imatinib or known hypersensitivity to imatinib.
Clinically significant abnormal values for hematology, clinical chemistry or urinalysis at the screening and admission visits. Abnormalities considered to be non-clinically significant by the Investigator are acceptable.
Clinically significant abnormal physical examination or 12-lead electrocardiogram (ECG) at the screening or admission visits. NOTE: QTcF interval of > 450 msec in males or > 470 msec in females will be the basis for exclusion from the study. ECG may be repeated for confirmatory purposes if initial values obtained exceed the limits specified.
Clinically significant abnormal renal function defined as a creatinine clearance rate < 90 mL/min
Significant history (within six months prior to receiving the study drug) and/or presence of hepatic, renal, cardiovascular, pulmonary, gastrointestinal, endocrinological, hematological, dermatological, psychiatric, neurological, immunologic, ophthalmologic, metabolic, fluid retention and edema, bleeding disorders including hemorrhage or oncological disease.
Any subject with a history, presence and/or current evidence of serologic positive result for hepatitis B surface antigen, hepatitis C antibodies, or HIV antibodies 1 or 2.
Recent history (within previous six months prior to screening) of alcohol or drug abuse (as judged by the investigator), or has consumed > 2 alcohol drinks/day during the last three months prior to screening (one glass is approximately equivalent to: beer [284 mL], wine [125 mL/4 ounces], or distilled spirits [25 mL/1 ounce]). Subjects that consume three glasses of alcoholic beverages per day but less than 14 glasses per week may be enrolled at the discretion of the Investigator. Positive screens for alcohol or controlled substances at the screening or admission visits will disqualify a subject from study participation.
Any subject who currently uses or has regularly used tobacco or tobacco-containing products (cigarettes, pipes, etc.) for at least 30 days prior to screening or positive urine cotinine screen (>300 ng/mL) at the screening or admission visits.
Any subject who has received treatment with an investigational drug during the 30 days prior to screening. Exposure to an investigational medical device within 30 days of screening.
Use of agents known to affect drug metabolism: use of any known CYP3A4 inducers and/or inhibitors or consumed grapefruit juice, grapefruit, Seville oranges or St John's Wort or products containing these within 14 days prior to first administration of study drug. Strong inducers of CYP3A4 include dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifampicin and phenobarbital. Strong inhibitors of CYP3A4 include ketoconazole, itroconazole, clarythromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin and voriconazole.
Investigative site personnel or their immediate families (spouse, parent, child or sibling whether biological or legally adopted).
Any subject unwilling or unable to comply with study procedures.
Pregnant or nursing women.
Anyone who does not meet the requirements for exclusion of certain concomitant medications as defined in Section 7.5.
