Temodar Plus Tyrosine Kinase Inhibitors for Progressive CNS Disease

NCT04541407 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 1

No results posted yet for this study

Summary

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).

Conditions

  • Non Small Cell Lung Cancer
  • CNS Progression

Interventions

DRUG

Temozolomide plus Osimertinib

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.
