Overview
Brief Summary
AINV18P1 is a Phase 1 study where palbociclib will be administrated in combination with a standard re-induction platform in pediatric relapsed Acute Lymphoblastic Leukemia (ALL) and lymphoblastic lymphoma (LL). LL patients are included because the patient population is rare and these patients are most commonly treated with ALL regimens. The proposed palbociclib starting dose for this study will be 50 mg/m^2/day for 21 days.
Detailed Description
PRIMARY OBJECTIVES:
I. To estimate the maximum tolerated dose (MTD) and/or recommended Phase 2 dose (RP2D) of palbociclib administered in combination with re-induction chemotherapy in pediatric patients with relapsed B- or T-lineage ALL/LL.
II. To define and describe the toxicities of palbociclib administered on this schedule.
III. To characterize the pharmacokinetics of palbociclib in pediatric patients with relapsed B- or T-lineage ALL/LL.
SECONDARY OBJECTIVES:
I. To preliminarily define the antitumor activity of palbociclib in combination with chemotherapy for children with relapsed ALL/LL within the confines of a Phase 1 study.
II. To assess the biologic activity of palbociclib in this patient population.
OUTLINE:
Patients receive Palbociclib PO (or via NG-tube) once daily on Days 1-21; Intrathecal cytarabine (IT ARAC) on Day 1, Doxorubicin IV push or infusion over 1-15 min on Day 4; Prednisone or prednisolone PO on days 4-31; Vincristine IV push or mini-bag per institutional policy on Days 4, 11, 18, and 25; and Pegaspargase IV over 1-2 hours on Days 5, and 18. If CNS3 leukemia is present, patients receive Intrathecal Triple Therapy (ITT) on days 4, 11,18, and 25. If CNS1 or 2 disease status, patients receive Methotrexate (IT MTX) on Days 18 and 32. Patients known to be CNS3 at study entry may receive ITT on Day 1 rather than IT ARAC. Treatment will be given for one cycle, 32 days, in the absence of disease progression or unacceptable toxicity.

Inclusion Criteria
- •Patients with recurrent or refractory B- or T-lineage lymphoblastic leukemia and lymphoma.
- •Patients with leukemia must have ≥ 5% (M2 or M3) bone marrow blasts with or without an extramedullary site of relapse. Morphologic relapse for M2 should be confirmed using flow cytometry, FISH and/or cytogenetics or molecular techniques.
- •Patients with LL must have either measurable or evaluable disease.
- •Patients with first or greater relapsed T-lineage ALL or LL and second or greater relapsed B-lineage ALL or LL are eligible.
- •Patients with primary refractory disease with at least 2 prior induction attempts or first relapse refractory to at least one prior re-induction attempt are eligible.
- •Karnofsky \>= 50% for patients \> 16 years of age and Lansky \>= 50 for patients \<= 16 years of age.
- •Note: Patients who are unable to walk because of paralysis, but who are up in a wheelchair, will be considered ambulatory for the purpose of assessing the performance score.
- •Patients must have fully recovered from the acute toxic effects of all prior anti-cancer therapy and must meet the following minimum duration from prior anti-cancer directed therapy prior to enrollment. If after the required timeframe, the numerical eligibility criteria are met, e.g., blood count criteria, the patient is considered to have recovered adequately.
- •Cytotoxic chemotherapy or other anti-cancer agents known to be myelosuppressive. See DVL homepage for commercial and Phase 1 investigational agent classifications. For agents not listed, the duration of this interval must be discussed with the study chair and the study-assigned Research Coordinator prior to enrollment.
- •A waiting period prior to enrollment is not required for patients receiving standard cytotoxic maintenance chemotherapy (i.e., corticosteroid, vincristine, 6MP, and/or methotrexate).
Exclusion Criteria
- •Pregnant or breast-feeding women will not be entered on this study due to risks of fetal and teratogenic adverse events as seen in animal/human studies. Based on the mechanism of action, palbociclib may be expected to cause fetal harm if used during pregnancy. Pregnancy tests must be obtained in girls who are post-menarche. Males or females of reproductive potential may not participate unless they have agreed to use an effective contraceptive method for the duration of study therapy. Women of reproductive potential should use effective contraception during treatment and for at least 3 weeks after the last dose of palbociclib. Males with female partners of reproductive potential should use effective contraception during treatment and for 3 months after the last dose of palbociclib. Animal data suggests that palbociclib may affect male fertility.
- •Prednisone or methylprednisolone for ≤ 120 hours (5 days) may be administered for cytoreduction up to 24 hours prior to the start of protocol therapy and as treatment for allergic reactions or for physiologic replacement/stress dosing of hydrocortisone for documented adrenal insufficiency. Corticosteroids are not allowed for other indications. If used to modify immune adverse events related to prior therapy, ≥ 14 days must have elapsed since last dose of corticosteroid.
- •Patients who are currently receiving another investigational drug.
- •Patients who are currently receiving other anti-cancer agents are not eligible \[except patients receiving hydroxyurea, which may be continued until 24 hours prior to start of protocol therapy\].
- •Patients who are currently receiving drugs that are strong inhibitors and/or inducers of CYP3A4 or sensitive CYP3A4 substrates and CYP3A4 substrates with a narrow therapeutic range are not eligible. Strong inducers or inhibitors of CYP3A4 are prohibited from 14 days prior to enrollment to the end of the study.
- •Patients who are receiving cyclosporine, tacrolimus or other agents to prevent graft-versus-host disease post bone marrow transplant.
- •Patients must be able to swallow intact capsules or liquid. Patients that are unable to swallow oral medications may receive palbociclib through an NG tube. G tube administration is not allowed.
- •Patients who have an uncontrolled infection defined as below:
- •Fever above 38.2°C within 48 hours of study enrollment with clinical signs of infection. Fever that is determined to be due to tumor burden is allowed if patients have documented negative blood cultures for at least 48 hours prior to enrollment and no concurrent signs or symptoms of active infection or hemodynamic instability.
- •A positive fungal culture within 30 days of study enrollment or active therapy for presumed invasive fungal infection.
