Phase 2 Trial With a Safety Run-in of Combinatorial Therapies With Intrathecal (IT) Dendritic Cell Vaccines (cDC1s) inHER+ (Combined With IT Trastuzumab) and HER2- (Combined With IT Nivolumab) Breast Cancer (BC) Leptomeningeal Disease (LMD)
H. Lee Moffitt Cancer Center and Research Institute
Summary
The purpose of this study is to learn about the effects of the study treatment, Dendritic Cell Vaccine (DCV), in combination with trastuzumab or nivolumab to confirm the highest dose of the study treatment that can be given safely to participants with Breast Cancer (BC) with Leptomeningeal Disease (LMD).

Inclusion Criteria: * Histologically or cytologically confirmed diagnosis of BC by ASCO/CAP guidelines (Wolff et al, 2018), or radiographically definite LMD from BC. * Trial participants must have a diagnosis of LMD. They must have the presence of malignant cells in the CSF (CSF+; note now cytology is considered diagnostic of LMD if the cytology is read as positive or suspicious; \[Chamberlain et al., 2017\] OR characteristic radiographic abnormalities of LMD). Signs and symptoms of LMD in and of themselves are not sufficient for inclusion. * Patients must have an ECOG performance scale of ≤2…
