    Abstract: Primary brain tumors are a major cause of cancer mortality in the United States. Therapy for gliomas, the most common type of primary brain tumors, remains suboptimal. The development of improved therapeutics will require greater knowledge of the biology of gliomas at both the genomic and transcriptional levels. We have previously reported whole genome profiling of chromosome copy number alterations (CNA) in gliomas, and now present our findings on how those changes may affect transcription of genes that may be involved in tumor induction and progression. By calculating correlation values of mRNA expression versus DNA copy number average in a moving window around a given RNA probe set, biologically relevant information can be gained that is obscured by the analysis of a single data type. Correlation coefficients ranged from −0.6 to 0.7, highly significant when compared with previous studies. Most correlated genes are located on chromosomes 1, 7, 9, 10, 13, 14, 19, 20, and 22, chromosomes known to have genomic alterations in gliomas. Additionally, we were able to identify CNAs whose gene expression correlation suggests possible epigenetic regulation. This analysis revealed a number of interesting candidates such as CXCL12, PTER, and LRRN6C, among others. The results have been verified using real-time PCR and methylation sequencing assays. These data will further help differentiate genes involved in the induction and/or maintenance of the tumorigenic process from those that are mere passenger mutations, thereby enriching for a population of potentially new therapeutic molecular targets.

    Abstract: BAY 2666605, co-developed by the Broad Institute and Bayer Pharmaceuticals, is a selective and potent molecular glue, part of a family of small molecules recently baptized as ‘velcrins’, that induces complex formation between phosphodiesterase 3A (PDE3A) and SLFN12. BAY 2666605 has recently entered a First-in-Human study (NCT04809805) in patients with advanced solid tumors and here we describe its pre-clinical pharmacology profile. DNMDP, the precursor to BAY 2666605, was discovered in a phenotypic screen of genomically annotated cancer cell lines and sensitivity to treatment correlated to high expression of PDE3A (1). Upon treatment, SLFN12 is recruited into a stable complex with PDE3A where its RNase activity is enhanced and required for response (2). BAY 2666605 is a potent complex inducer (EC50 = 7 nM) and cytotoxic in vitro with nanomolar potency (IC50 = 1nM, in the most sensitive cell lines). Cancer cells with high expression of PDE3A and co-expression of SLFN12 are killed by a mechanism independent of PDE3A enzymatic inhibition. PDE3A-SLFN12 binding is required for cytotoxicity. Biomarker-positive lines are enriched in the melanoma lineage and show dose-dependent sensitivity to BAY 2666605 both in vitro and in vivo. Notably, we have consistently observed tumor regression in biomarker-positive melanoma models, including in PDX models (10mg/kg po BID). Based on target expression data from TCGA and tumor arrays, various other tumor types also co-express PDE3A and SLFN12, such as sarcomas and ovarian cancer. To this end, we show that BAY 2666605 inhibits tumor growth of PDX models of sarcoma and ovarian cancer in vivo. BAY 2666605 has excellent brain penetration, making glioblastoma a promising indication. Biomarker-positive GBM models are sensitive to BAY 2666605 both in vitro and in vivo. In a subset of orthotopic GBM models BAY 2666605 treatment has significant impact on survival. In BAY 2666605 treated models we have observed MCL1 downregulation and this biomarker will be evaluated in clinical settings. Our pre-clinical data indicate that BAY 2666605 is a potent anti-tumor agent with first-in-class potential and broad indication space. 1. de Waal et al.

    Abstract: Velcrin compounds are a class of small molecules that induce complex formation between PDE3A and SLFN12, killing cancer cells that express elevated levels of these two proteins by a mechanism independent of PDE3A enzymatic inhibition. Instead, PDE3A binding stimulates the RNase activity of SLFN12, resulting in cleavage of the specific SLFN12 substrate, tRNA-Leu-TAA. Cleavage of tRNA-Leu-TAA in turn causes ribosomal pausing, inhibition of protein synthesis, and cancer cell death. Unlike traditional targeted therapies that leverage dependencies created in cancer cells by genomic alterations, velcrins instead kill cancer cells by a gain-of-function mechanism dependent on the RNase activity of SLFN12. In a collaboration between the Broad Institute and Bayer Pharmaceuticals, we developed the first velcrin, BAY 2666605, to enter Phase I clinical trials. BAY 2666605 is active in cell line and patient-derived xenografts of several tumor types, specifically where elevated levels of the two biomarkers, PDE3A and SLFN12, are expressed. Biomarker-positive tumors are especially enriched among melanomas, and we have consistently observed tumor regression in biomarker-positive melanoma tumor models in vivo. BAY 2666605 furthermore shows drug-like properties, excellent brain penetration, increased stimulation of SLFN12 RNase activity, and reduced inhibition of PDE3A enzymatic activity compared with most other velcrins and approved PDE3A inhibitors. BAY 2666605 has recently entered a First-in-Human study (NCT04809805) in patients with advanced solid tumors that co-express PDE3A and SLFN12, including melanoma, ovarian cancer, and sarcoma.

    Abstract: Although lung adenocarcinomas frequently metastasize to the brain, treatment options for lung adenocarcinoma brain metastases (BM-LUAD) are limited. We discovered novel candidate drivers of progression by using case-control analyses to compare whole-exome sequencing data from a cohort of 73 BM-LUAD to a control cohort of 503 primary lung adenocarcinomas. We identified MYC, YAP1 and MMP13 as genomic regions with significantly more frequent amplifications in BM-LUAD compared to control cohort. We validated that MYC, YAP1 and MMP13 can drive brain metastases in a patient-derived xenograft mouse model, where incidence of brain metastases was higher in mice injected with tumor cells expressing the candidate drivers compared to tumor cells expressing LacZ. These results indicate that somatic alterations can drive lung adenocarcinomas to metastasize to the brain. These candidate drivers may serve as therapeutic targets in patients with brain metastatic lung adenocarcinomas. Citation Format: Naema Nayyar, David J.
