3 Clinical Trials for Various Conditions
This study will examine the safety and efficacy of pertuzumab in combination with high-dose trastuzumab in adult participants with HER2-positive MBC with CNS metastases and disease progression in the brain following radiotherapy.
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).
This study is to collect and validate regulatory-grade real-world data (RWD) in oncology using the novel, Master Observational Trial construct. This data can be then used in real-world evidence (RWE) generation. It will also create reusable infrastructure to allow creation or affiliation with many additional RWD/RWE efforts both prospective and retrospective in nature.
