SNU-407 cells were treated with a combination of varying concentrations of MRTX1133 with varying concentrations of either afatinib, sapitinib, or pelitinib for 72 hours. Absorbances were normalized to DMSO control for % viability. The attached files were compiled in data format from n=2 data sets (6 data points total for each combination) and uploaded to SynergyFinder+ with % viability chosen as response.

Colorectal cancer (CRC) is the second leading cause of cancer deaths worldwide, with roughly 41% of CRC cases harboring a KRAS mutation. There have been significant advances with the advent of KRAS-targeted therapies; however, acquired resistance to KRAS-targeted treatments has occurred in other cancers, with mechanisms including increased HER family expression among other receptor tyrosine kinases. HER3, a member of the HER family that is kinase impaired, has been shown to be a resistance mechanism upon inhibition of the HER family and downstream targets including RAS/MEK/ERK and PI3K/AKT. Our study examines whether HER3 and mutant KRAS are viable co-targets. We find that KRAS mutations tend to co-occur with HER3 alterations in a large panel of cancers and in CRCs. Our results show that both total and activated HER3 levels increase in CRC patient derived organoids and cell lines after treatment with KRASG12D targeted agents, indicating that HER3 could be a potential adaptive response mechanism to KRAS-targeted therapy. Further, we found that genetic knock-down of KRAS and HER3 resulted in a statistically significant reduction in growth of CRC cells compared to single knockdown of either KRAS or HER3. We observed that kinase impaired HER3 binding partners, as assessed by immunoprecipitation, is cell dependent with EGFR binding HER3 in one cell line. After co-treating CRC cells with pan-HER inhibitors in combination with MRTX1133, a KRASG12D inhibitor, synergistic and additive effects in reduction in cell growth were observed in a drug-dependent manner. Finally, we found that co-targeting KRASG12D mutant cells with a KRASG12D inhibitor and a HER3 antibody-drug conjugate further reduced cell viability. We posit that co-targeting both KRASG12D and HER3, whether directly or indirectly, is a potential therapeutic strategy in CRC patients.
Hearing data obtained using Bone Conduction Auditory Brainstem Response (BC-ABR) testing on six Greater Caribbean Manatees being rehabilitation at the Caribbean Manatee Conservation Center in Bayamon, Puerto Rico. Hearing data was collected while hearing assessments were conducted for clinical assessments of hearing.
