E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To estimate the maximum tolerated dose(s) (MTD (s)) and/or to identify the recommended dose for expansion (RDE) for two age groups (≥3 months to ≤2 years: >2years to <18 years) of pediatric patients with AML or MLL based on the rate of dose-limiting toxicity (DLT) of midostaurin administered orally in dose ranges studied in adults. |
|
E.2.2 | Secondary objectives of the trial |
Secondary Objectives:
• To characterize the safety and tolerability of midostaurin, including acute and chronic toxicities
• To characterize the population PK and trough of single and repeated doses of midostaurin and its metabolite(s)
• To determine the response rates, time to relapse and overall survival of patients treated with midostaurin
Exploratory Objectives:
• To determine the presence of activating mutations or WToverexpression of the FLT3 gene in MLL-rearranged ALL and AML samples
• To correlate baseline levels of FLT3 phosphorylation with FLT3
expression levels and clinical outcome in MLL pts.
• To correlate baseline levels of FLT3 phosphorylation with activating FLT3 mutations and clinical outcome in AML pts.
• To evaluate changes in FLT3 phosphorylation following treatment with midostaurin, and correlate changes with clinical outcome
• To evaluate changes in FLT3 phosphorylation following treatment with midostaurin, and correlate with pharmacokinetic data |

E.3 | Principal inclusion criteria |
1. Patients must have a documented diagnosis of one of the following leukemias:
• MLL-rearranged ALL, refractory to standard induction treatment or in first or subsequent relapse
• FLT3-mutated AML refractory to standard induction (after failure of at least 2 different induction chemotherapy regimens) or refractory to reinduction at 1st relapse (after failure of the first re-induction course), or in second or greater relapse
2. Patients must be less than 18 years of age and ≥3 months of age.
3. Patients must have a Lansky/Karnofsky performance status ≥ 60.
4. Patients must have the following laboratory values reflecting
appropriate organ function:
• AST and ALT ≤ 5x Upper Limit of Normal (ULN),
• Serum Bilirubin ≤ 1.5 x ULN,
• Serum Creatinine ≤ 2 x ULN.
5. Patients must have an expected survival of greater than 8 weeks.
6. Parent or legal guardian and/or the patient must give written
informed consent, according to local law and regulations. |
|
E.4 | Principal exclusion criteria |
1. Patients with symptomatic leukemic CNS involvement.
2. Patients with isolated extramedullary leukemia.
3. Patients must have recovered from prior cytotoxic chemotherapy, with a minimum wash-out time of previous chemotherapy of 72 hours. For intrathecal chemotherapy, the minimum wash-out time is 48 hours (other exceptions for intrathecal chemotherapy are noted in Section 6.6.5)
4. Patients who had prior allogeneic, syngeneic or autologous bone
marrow or stem cell transplant less than 2 months from Day 1
5. Patients who have received any investigational agent within 30 days or 5 half-lives, whichever is greater, prior to Day 1. An investigational agent is an agent with no approved medical uses in adults or pediatrics.
6. Patients who have had prior treatment with a FLT3 inhibiting drug or investigational agent; except for sorafenib.
7. Use of CYP3A4/5 enzyme inducing or inhibiting drugs or CYP3A4/5 enzyme inducing or inhibiting herbal supplements while on study treatment
8. The use of corticosteroids while on study drug (exceptions are noted in Section 6.6.5)
9. Patients who have had any surgical procedure, excluding central
venous catheter placement or other minor procedures (e.g. skin or bone marrow biopsy), within 14 days of Day 1.
10. Patients with any other known disease concurrent severe and/or uncontrolled medical condition (e.g. cardiovascular disease including congestive heart failure or active uncontrolled infection) which could compromise participation in the study.
11. Patients with an abnormal chest X-ray and/or any pulmonary
infiltrate including those suspected to be of infectious origin. In
particular, patients with resolution of clinical symptoms of pulmonary infection but with residual pulmonary infiltrates on chest x-ray are not eligible until pulmonary infiltrates have completely resolved.
12. Patients with known impairment of gastrointestinal (GI) function or GI disease that may significantly alter the absorption of midostaurin, including active graft-versus-host disease of the liver or the gut.
13. Patients with a known confirmed diagnosis of HIV infection or active viral hepatitis.
14. Patients with a left ventricular shortening fraction < 27% as
determined by MUGA scan or echocardiogram
15. Patients with abnormal ECG including:
• QTcF ≥ 450 ms, PR ≥ 200 msec, QRS complex ≥ 110 msec, at screening or prior to first dosing
• Any cardiac conduction abnormality
• Any morphologic abnormality
• Any ST/T wave abnormality
• Any atrial or ventricular arrhythmia
16. Female patients who are pregnant or breast feeding. Women of childbearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for at least 3 months after the last exposure to midostaurin.
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) or 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 partner sterilization (at least 6 months prior to screening).
During the study the vasectomized male partner should be the sole partner for that subject.
OR:
• Combination of any two of the following (a+b or a+c, or b+c):
a) Use of oral, injected or implanted hormonal methods of contraception or other forms of hormonal contraception that have comparable efficacy (failure rate <1%), for example hormone vaginal ring or transdermal hormone contraception.
b) Placement of an intrauterine device (IUD) or intrauterine system
(IUS)
c) Barrier methods of contraception: Condom or Occlusive cap
(diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository
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
17. Sexually active males unless they use a condom during intercourse while taking midostaurin and for at least 3 months after the last exposure to midostaurin. They should not father a child until three months after the end of the study. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
18. Patients/parents unwilling or unable to comply with the protocol |
