Brigatinib in Relapsed or Refractory ALK-Positive Anaplastic Large Cell Lymphoma
Study Details
Study Description
Brief Summary
FDA approved drugs to treat patients with relapsed or refractory anaplastic large cell lymphoma (ALCL) has a median progression free survival of 20 months. Majority of patients relapse in 2 years. This study will evaluate overall response rate of next generation ALK inhibitor brigatinib in ALK positive ALCL patients by overcoming mechanisms of resistance to ALK inhibitors on cancer patients.

Detailed Description
Although patients with ALK+ anaplastic large cell lymphoma (ALCL), a type of peripheral T-cell lymphoma (PTCL), are considered to have a favorable prognosis, relapse is not uncommon if multiple International Prognostic Index (IPI) risk factors, age ≥ 40, and beta-2 microglobulin ≥ 3 mg/L are present at diagnosis. For patients older than 40 years at diagnosis and beta-2 microglobulin ≥ 3 mg/L, progression-free survival (PFS) and overall survival (OS) is less than 50% at 2.5 years when treated with standard anthracycline-based induction therapy. Patients with ALK+ ALCL with 3 or more IPI risk factors have a 5-year PFS rate of only 20% to 30%. In total, approximately 40 to 65% of patients with ALCL develop recurrent disease after front-line chemotherapy and at relapse, the disease is historically resistant to conventional chemotherapy.
Current FDA approved for treatment of relapsed or refractory PTCLs have a median PFS of 20 months and majority of patients relapse within 2 years. Despite ALK tyrosine kinase being an attractive target for management of relapsed or refractory ALK+ ALCL, ALK gene rearrangement makes cancer resistant to first and 2nd generation ALK inhibitors. Brigatinib is a next generation inhibitor with broad activity aganst a broad spetrum of resistant ALK mutants. Brigatinib has been shown to overcome mechanisms associated with resistane to 1st and 2nd generation ALK inhibitors. It is approved as 2nd line of treament in non small cell lung cancer patients. and is being tested in patients with relapsed or refractory ALK-positive ALCL.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Brigatinib 90 mg daily orally for 7 days, then 180 mg daily orally during first cycle; 180 daily orally thereafter during every subsequent cycle. Each cycle has 28 days |
Drug: Brigatinib
Brigatininb is administered in tablet form. It is to be taken until disease progression, unacceptable toxicity or completion of 24 cycles. patients may continue to take brigatininb beyond 24 cycles if they are benefiting from the drug

Outcome Measures
Primary Outcome Measures
- objective response rate [2 years]
proportion of patients with tumor size reduction of a predefined amount and for a minimum time period measured using RECIL 2017 criteria
Secondary Outcome Measures
- To assess the incidence of adverse events as assessed by NCI CTCAE v5.0 for 2 years [2 years]
Adverse events will be documented by NCI CTCAE v 5.0 criteria
- To measure the overall survival (OS) at 1 and 2 years from treatment initiation [5 years]
Overall survival will be measured as the length of time patients survive from the day of treatment.
- To measure progression-free survival (PFS) at 1 and 2 years from treatment initiation [5 years]
Progression free survival will be measured as the length of time from treatment to progression of disease as measured by radiologic evaluation
- To measure the duration of response (DOR) for the period of 2 years [2 years]
DOR will be length of time from initial response to tumor progression documented by radiologic evaluation
Other Outcome Measures
- To evaluate the frequency of NPM/ALK quantitative polymerase chain reaction (qPCR) positivity in plasma [2 years]
Detection of the NPM/ALK fusion gene via quantitative PCR (qPCR) in plasma
- The evaluate the persistence of NPM/ALK DNA construct in plasma and correlation with rate of relapse [2 years]
NPM-ALK DNA construct in plasma will be measured prospectively by polymerase chain reaction
- To evaluate for ALK mutations in tumor and plasma at baseline and at time of relapse [2 years]
ALK mutations in tumor and plasma will be analyzed by next generation sequencing
- Changes in ALK-dependent NF-kB activation [2 years]
NFKB1 and NFKB2 nuclear translocation/accumulation will be tested by immune histochemistry (IHC)
- Changes in ALK phosphorylation [2 years]
ALK phosphorylation (indicator of brigatinib efficacy) will be tested by immune histochemistry (IHC)
- Changes in TRAF2 expression [2 years]
TRAF2 expression (E3 ligase required for ALK mediation of NF-kB activation) will be tested by immune histochemistry (IHC)
- To evaluate gene expression profiles before and after treatment with brigatinib [2 years]
Gene expression profiling of NF-kB will be performed in tumor before and after treatment with brigatinib
Eligibility Criteria
Criteria
Inclusion Criteria:
