Interventions

  • Temozolomide plus Osimertinib — DRUG
    Temozolomide is an oral alkylating chemotherapy which has good CNS penetration and has demonstrated CNS responses in both primary brain tumors (e.g., glioblastoma and anaplastic astrocytoma) and in small cell lung cancer (SCLC) brain metastases. Preclinical data from glioblastoma suggests potential synergy of concurrent ALK or EGFR inhibition with temozolomide and early phase trials in glioblastoma are ongoing investigating such combinations. It is felt that combining temozolomide with osimertinib or lorlatinib may be beneficial for patients with progressive CNS disease on either of these TKIs because of the high CNS penetration of temozolomide, good CNS activity of temozolomide in other tumor types and preclinical data from glioblastoma suggesting a potential enhanced effect of concurrent EGFR and ALK/ROS1 inhibition with temozolomide.

Study Details

This trial is testing two novel combinations (temozolomide plus osimertinib OR temozolomide plus lorlatinib) which have not been evaluated in clinical trials. Thus, the exact benefits of these novel combinations are unclear. However, based on the mechanism of action of temozolomide and CNS(Central Nervous System) penetration/activity in other tumor types, it is hypothesized that adding temozolomide to osimertinib or temozolomide to lorlatinib may provide improvement in CNS disease control in patients with CNS progression on either of these latter two TKIs (Tyrosine kinase inhibitors).

Arms

  • Experimental: Exon 19 deletions or L858R point mutations in exon 21
    Will include patients with exon 19 deletions or L858R point mutations in exon 21 of the epidermal growth factor receptor (EGFR) gene. Temozolomide plus Osimertinib will be the study drug combination administered. Osimertinib will be given at a fixed dose of 80 mg daily for dose level 1, with a potential to increase to 160 mg daily for dose level 2. Temozolomide will be started at a dose of 150 mg/m2 on days 1-5 of a 28 day cycle for cycle 1 and if tolerated will be increased to 200 mg/m2 on days 1-5 of a 28 day cycle for cycles 2+. There will be a -1 dose level.
  • Experimental: Patients with anaplastic lymphoma kinase (ALK) fusions
    Will include patients with anaplastic lymphoma kinase (ALK) fusions. Temozolomide plus Lorlatinib will be the study drug combination administered. Lorlatinib will be given at a fixed dose of 100 mg daily. Temozolomide will be started at a dose of 150 mg/m2 on days 1-5 of a 28 day cycle for cycle 1 and if tolerated will be increased to 200 mg/m2 on days 1-5 of a 28 day cycle for cycles 2+. There will be a -1 dose level depending on tolerability.
