Trial ID: NCT02538965
To determine the activity of lenalidomide in the treatment of pediatric subjects with relapsed/refractory acute myeloid leukemia (AML) (with second or greater relapse or refractory to at least 2 prior induction attempts) measured by morphological complete response defined as either a CR or CRi within the first 4 cycles of treatment.
A Phase 2, Multicenter, Single-arm, Open-label Study to Evaluate the Activity, Safety and Pharmacokinetics of Lenalidomide (Revlimid®) in Pediatric Subjects From 1 to = 18 Years of Age With Relapsed or Refractory Acute Myeloid Leukemia.

voluntarily provide permission to the ICF/IAF prior to conducting any study-related
3. Participants have relapsed or refractory acute myeloid leukemia after at least 2 prior
- Bone marrow aspirate or biopsy must have ≥ 5% blasts by morphology and/or flow
- Each block of chemotherapy is a separate reinduction attempt.
- Donor lymphocyte infusion (DLI) is considered a reinduction attempt.
4. Participants are willing and able to adhere to the study visit schedule and other

Lansky score ≥ 50% (participants < 16 years of age).
6. Participants have a resting left ventricular ejection fraction (LVEF) of ≥ 40%
obtained by echocardiography.
7. Participants have recovered from the acute toxic effects of all prior chemotherapy,
immunotherapy, or radiotherapy prior to first dose. All prior treatment-related
toxicities must have resolved to ≤ Grade 2 prior to enrollment.
8. Regarding radiation therapy, time elapsed prior to first dose of lenalidomide:
- 2 weeks for local palliative radiation therapy (XRT).
- 8 weeks if prior craniospinal chemoradiation therapy (CRT) or if ≥ 50% radiation
- 6 weeks if other bone marrow radiation has been administered.
9. Graft-versus-host disease criteria:
- Participants must be at least 2 months (from first dose of lenalidomide) from
stem cell infusion.
- Participants must have no evidence of active acute or chronic GVHD (Grade 0) for
4 weeks prior to the first dose of lenalidomide.
- If the participants have a history of maximum Grade 1 or 2 GVHD that was treated
with systemic steroid (≥ 0.5 mg/kg/day prednisone equivalents) or other
non-steroid systemic IST, the participant must be off all IST for at least 2
weeks, and must have ceased treatment doses of steroids for GVHD (≥ 0.5 mg/kg/day
prednisone equivalents) for at least 4 weeks.
- If the participants have a history of Grade 3 or greater GVHD, the
participants must be off all systemic IST for 4 weeks
- Topical therapy is permitted and does not imply the participants have active
acute or chronic GVHD.
- Physiologic dosing of hydrocortisone is permitted.
10. At least 4 weeks (from first dose) elapsed from donor lymphocyte infusion (DLI)
11. Participants have adequate renal function, which is defined as:
- Creatinine clearance calculated using the Schwartz formula, or radioisotope
glomerular filtration rate (GFR) > 70 mL/min/1.73 m2.
12. Participants have adequate liver function, which is defined as:
- Total bilirubin is ≤ 2 mg/dL unless the increase in bilirubin is attributable to
- Aspartate aminotransferase (AST) is ≤ 3.0 x upper normal limit (ULN) for age. For
the purpose of this study, the ULN for AST is 50 U/L.
- Alanine transaminase (ALT) is ≤ 3.0 x upper normal limit (ULN) for age. For the
purpose of this study, the ULN for ALT is 45 U/L.
13. Female Children of Childbearing Potential (FCCBP), Female of Childbearing Potential
(FCBP) and male participants that have reached puberty must agree to undergo
physician-approved reproductive education and discuss the side effects of the study
therapy on reproduction with parent(s) and/or guardian(s).
14. All participants and/or parents/guardians must have an understanding that lenalidomide
could have a potential teratogenic risk. Female children of childbearing potential, is
defined as females who have achieved menarche and/or breast development in Tanner
Stage 2 or greater and have not undergone a hysterectomy or bilateral oophorectomy and
FCBP defined as a sexually mature woman who has not undergone a hysterectomy or
bilateral oophorectomy and has not been naturally postmenopausal for at least 24
consecutive months (ie, has had menses at any time in the preceding 24 consecutive
months) must meet the following conditions below (Note: Amenorrhea following cancer
therapy does not rule out childbearing potential):
- Medically supervised serum pregnancy tests with a sensitivity of at least 25
mIU/mL must be conducted in FCCBP/FCBP, including those who commit to complete
abstinence*. FCCBP/FCBP must have two pregnancy tests (with a minimum sensitivity
of 25 mIU/mL) prior to starting treatment with lenalidomide. The first pregnancy
test must be performed within 10 - 14 days prior to the start of lenalidomide
treatment and the second pregnancy test must be performed within 24 hours prior
to starting treatment with lenalidomide.
NOTE: The pregnancy test 10 to 14 days prior to initiation of lenalidomide may be omitted,
at the discretion of the investigator, for any FCCBP/FCBP who has high acuity disease
requiring immediate treatment with lenalidomide. The pregnancy test within 24 hours prior
to the first dose of lenalidomide is required to be performed.
The participants may not received Investigational Product (IP) until the investigator has
verified that the results of these pregnancy tests performed on Cycle 1 Day 1 are negative.
FCCBP/FCBP with regular or no menstrual cycles must agree to have pregnancy tests weekly
for the first 28 days of study participation and then every 28 days while on study, at
study Treatment Discontinuation Visit, and at Day 28 following IP discontinuation. If
menstrual cycles are irregular, the pregnancy testing must occur weekly for the first 28
days and then every 14 days while on study, at study Treatment Discontinuation Visit, and
at Days 14 and 28 following IP discontinuation.
- Female participants must, as appropriate to age and at the discretion of the study
Investigator, either commit to true abstinence* from heterosexual contact (which must
be reviewed on a monthly basis) and/or agree to the use of two reliable forms of
approved and effective contraceptive methods simultaneously. The two methods of
reliable contraception must include one highly effective method and one additional
effective (barrier) method (oral, injectable, or implantable hormonal contraceptive;
tubal ligation; intra-uterine device; barrier contraceptive with spermicide; or
vasectomized partner) without interruption, 28 days prior to starting lenalidomide
treatment, throughout the entire duration of study treatment including dose
interruptions and 28 days after the end of study treatment.
- All male and female participants must follow all requirements defined in the Pregnancy
16. Male participants, as appropriate to age and the discretion of the study
- Must practice true abstinence* or agree to use a condom during sexual contact with a
pregnant female or a female of childbearing potential while participating in the
study, during dose interruptions and for at least 28 days following lenalidomide
discontinuation, even if he has undergone a successful vasectomy or practices complete
