Study of Lorlatinib (PF-06463922)

Status: Recruiting
Phase:
DFCI Protocol ID: 17-393

Lorlatinib is a novel inhibitor across ALK variants, including those resistant to crizotinib. In this first pediatric phase 1 trial of lorlatinib, the drug will be utilized as a single agent and in combination with chemotherapy in patients with relapsed/refractory neuroblastoma. The dose escalation phase of this study (Cohort A1) uses a traditional Phase I 3+3 design. Once a recommended phase 2 pediatric dose is identified, an expansion cohort of 6 patients (Cohort B1), within which ALKi naïve patients will be prioritized, will be initiated. Parallel cohorts will be initiated in adults or patients with large BSA (Cohort A2) and in combination with chemotherapy upon establishing RP2D (Cohort B2).

Eligibility Criteria

Inclusion Criteria:

  -  Patients must have a diagnosis of neuroblastoma either by histologic verification of
     neuroblastoma and/or demonstration of tumor cells in the bone marrow with increased
     urinary catecholamines

  -  Patients are required to have an activating ALK aberration in their tumor detected by
     certified assay (i.e. CLIA in the US.) prior to registration. The report from this
     test is required to be submitted for eligibility. Patients with at least one of the
     following genetic features in their tumor will be considered to have an activating ALK
     aberration:

       1. An ALK activating mutation;

       2. ALK amplification (> 10 signals of the ALK gene);

       3. Presence of any ALK fusion protein that arises from a chromosomal translocation.

  -  Patients must have high risk neuroblastoma according to COG risk classification at the
     time of study registration. Patients who were initially considered low or intermediate
     risk, but then reclassified as high risk are also eligible.

  -  Patients must have at least ONE of the following: 1) Recurrent/progressive disease at
     any time prior to study enrollment, 2) Refractory disease, 3) Persistent disease

  -  Patients must have at least ONE of the following: 1) Bone disease, 2) Any amount of
     neuroblastoma tumor cells in the bone marrow, 3) At least one soft tissue lesion that
     meets criteria for a TARGET lesion, 4) At least one non-target soft tissue lesion that
     is not measurable, but had a biopsy positive for neuroblastoma and/or
     ganglioneuroblastoma at any time prior to enrollment or is MIBG avid

  -  Patients must have a Lansky (≤16 years) or Karnofsky (> 16 years) score of at least 50

  -  Patients must have fully recovered from the acute toxic effects of all prior
     chemotherapy, immunotherapy, or radiotherapy prior to entering this study.

  -  Patients must not have been previously treated with lorlatinib.

  -  Patients must not have received any of the specified therapies as stated in the
     protocol in the time period prior to registration

  -  Patients must not be receiving any other anti-cancer agents or radiotherapy at the
     time of study entry or while on study.

  -  Patients must not be receiving other investigational medications (covered under
     another IND) within 30 days of study entry or while on study.

  -  Patients must not be receiving chronic systemic corticosteroids at doses greater than
     physiologic dosing (inhaled corticosteroids acceptable).

  -  Patient must meet the organ function and system function requirements as stated in the
     protocol

Exclusion Criteria:

  -  Pregnancy, breast feeding, or unwillingness to use effective contraception during the
     study.

  -  Patients who, in the opinion of the investigator, may not be able to comply with the
     safety monitoring requirements of the study.

  -  Patients with disease of any major organ system that would compromise their ability to
     withstand therapy.

  -  Patients who have received prior allogeneic stem cell transplant

  -  Patients who are on hemodialysis.

  -  Patients with an active or uncontrolled infection.

  -  Known history of human immunodeficiency virus (HIV) infection, hepatitis B, or
     hepatitis C.

  -  Patient declines participation in NANT 2004-05, the NANT Biology Study
