ENDURE - Efficacy and Safety of AOP2014 With CML Patients in Remission (ENDURE-CML-IX)
Efficacy and Safety of Pegylated Proline Interferon Alpha 2b (AOP2014) in Maintaining Deep Molecular Remissions in Patients With Chronic Myeloid Leukemia (CML) Who Discontinue ABL-Kinase Inhibitor Therapy - a Randomized Phase III, Multicenter Trial With Post-study Follow-up

Detailed Description
Four hypotheses are tested in hierarchical order. To avoid inflation of type 1 error (false rejection of a null hypothesis), further confirmatory testing has to be stopped as soon as a null hypothesis could not be rejected.
All four hypotheses are tested at significance level 0.05. Null hypothesis 1 is the primary endpoint and investigates molecular relapse-free survival as a time-to-event variable; the two arms are compared with the log-rank test. Null hypotheses 2, 3, and 4 deal with probabilities of molecular relapse-free survival 7, 13, and 25 months after randomization, respectively; arms A and B are compared with the uncorrected chi-square test.

MR4 is defined as (i) detectable disease ≤0.01% BCR-ABL IS or (ii) undetectable disease in cDNA with ≥10,000 ABL or ≥24,000 GUS transcripts for at least one year. There have to be at least three consecutive PCR-results with MR4 or better within the last year (+ months) before study entry. The latest of these PCRs must be a confirmatory MR4 measurement prior to randomization by the EUTOS-certified Study Reference Laboratories for PCR (BCR-ABL mRNA). No PCR-results in the last year before randomisation can be worse than MR4. If the last PCR was not done within two months from baseline (day 0) in an EUTOS-certified study Reference Laboratory; the PCR sample must be sent to an EUTOS-certified study Reference Laboratory at screening.
- Patients who had failed to discontinue TKI in a prior discontinuation attempt are eligible for this protocol, if they fulfil criterion 5 after retreatment with TKI. A prior TKI discontinuation failure must be specifically indicated at inclusion and documented.

- Female patients with reproductive potential must agree to maintain highly effective methods of contraception by practicing abstinence or by using at least two methods of birth control from the date of consent through the end of the study. If abstinence could not be practiced, a combination of hormonal contraceptive (oral, injectable, or implants) and a barrier method (condom, diaphragm with a vaginal spermicidal agent) has to be used. Male patients must agree to use condoms during study participation.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: investigational arm A
There will be an overlapping treatment with AOP2014 and TKI for one month.
After one month, the TKI therapy will be stopped and patient will receive only AOP2014 treatment for the next 14 months.
|
AOP2014 as pre-filled auto-injection pen for subcutaneous injection, containing 250 µg AOP2014 / 0.5 ml.
The solution also contains inactive ingredients (sodium chloride, polysorbate 80, benzyl alcohol, sodium acetate, and acetic acid).
The solution is colorless to light yellow.
|
Other: surveillance arm B
This is an open-label study with a "surveillance" group as comparator arm.
Similar as in the arm A, patient will discontinue TKI therapy one month after randomization.
From then on patient will receive no further CML treatment.
|
For patients randomized into this treatment arm stopp their standard treatment and will just be under observation.
