Project description:This study will evaluate the safety, tolerability and preliminary efficacy of MK-8353 when administered in combination with pembrolizumab (MK-3475). There are two parts in this study: Part 1 will be dose escalation and confirmation, and Part 2 will be a cohort expansion. In Part 1, the recommended phase II dose (RP2D) of MK-8353 in combination with a fixed dose of pembrolizumab in participants with advanced malignancies will be identified and confirmed. Participants will be initially enrolled to receive MK-8353 at 350 mg twice a day (BID) in combination with pembrolizumab at a fixed dose of 200 mg on Day 1 of each 3-week cycle (Q3W) for up to 24 months of treatment. In Part 2, participants with advanced colorectal cancer (CRC) that is microsatellite stable (i.e., non-microsatellite instability-high/deficient mismatch repair [non-MSI-H/dMMR]) who received at least one and up to five prior lines of therapy will be enrolled at the RP2D in the expansion cohort to further evaluate safety and efficacy.
The protocol has been amended to lower the starting doses of MK-8353 in combination with pembrolizumab. In addition, 3 arms have been added: one in which MK-8353 will be administered continuously once a day (QD) in combination with pembrolizumab, one optional arm in which MK-8353 will be administered 1 week on/1 week off QD in combination with pembrolizumab and one optional arm in which participants undergo a MK-8353 QD run-in period prior to starting combination therapy with pembrolizumab.

Project description:MK: MK-801. Young male C57BL/6J mice received an injection of MK-801 (300 micro-g per g body weight). RNA from control mice were extracted 1hr, 2hr, 4hr, and 6hr after MK experimental mice received their last shock treatment. MK C+S: MK-801 & Context + Shock: Young male C57BL/6J mice received an injection of MK-801 (300 micro-g per g body weight) 1 h prior to contextual fear conditioning that consisted of: Placement into a novel spatial context for 2 min. After 2 min, a 1 sec (0.5 mA) shock was administered through a floor grid. The 2 min-1 sec shock paradigm was repeated for a total of 3 shocks. 1 min after the last shock, animals were removed to their homecage. RNA was extracted 1hr, 2hr, 4hr, and 6hr after the last shock treatment. Keywords: time-course

Project description:This is an open-label, two-part study to evaluate the safety and tolerability of combination treatment with dalotuzumab + MK-2206, dalotuzumab + MK-0752, or dalotuzumab + ridaforolimus (MK-8669). Part 1 of the study will determine the dose-limiting toxicities (DLTs) observed after administration of each of the combinations at various doses and define the maximum tolerated dose (MTD) of each combination. Part 2 of the study will assess preliminary anti-tumor activity of these combinations (at MTD) in two groups of participants with selected tumor biomarkers: one group with metastatic or recurrent platinum-resistant ovarian cancer, fallopian tube cancer, or primary peritoneal cancer and one group with metastatic or recurrent colorectal cancer. The dalotuzumab + ridaforolimus and dalotuzumab + MK-2206 arms will be enriched with female platinum-resistant ovarian cancer, fallopian tube cancer, or primary peritoneal cancer participants. The dalotuzumab + MK-0752 arm will be enriched with metastatic or recurrent wild-type kirsten rat sarcoma (KRAS) colorectal cancer participants.
The primary hypothesis is that the DLTs observed in adult patients with locally advanced or metastatic solid tumors after administration of each of the MK-MK doublets will be dose-dependent to allow for definition of a MTD within each MK-MK doublet.

Project description:The purpose of this study is to evaluate the safety and tolerability of humanized IgG4 (kappa) isotype monoclonal antibody against CEACAM1 (CM-24 [MK-6018]), administered intravenously as monotherapy and in combination with Pembrolizumab (MK-3475), in participants with selected advanced or recurrent malignancies. Escalating multiple doses will be evaluated to determine the recommended dose for Phase 2 clinical studies.

Project description:Introduction: Mammalian target of rapamycin (mTOR) represents a key downstream intermediate for a myriad of oncogenic receptor tyrosine kinases. In the case of the insulin-like growth factor (IGF) pathway, the mTOR complex (mTORC1) mediates IGF-1 receptor (IGF-1R)-induced estrogen receptor alpha (ERα) phosphorylation/activation and leads to increased proliferation and growth in breast cancer cells. As a result, the prevalence of mTOR inhibitors combined with hormonal therapy has increased in recent years. Conversely, activated mTORC1 provides negative feedback regulation of IGF signaling via insulin receptor substrate (IRS)-1/2 serine phosphorylation and subsequent proteasomal degradation. Thus, the IGF pathway may provide escape (e.g. de novo or acquired resistance) from mTORC1 inhibitors. It is therefore plausible that combined inhibition of mTORC1 and IGF-1R for select subsets of ER-positive breast cancer patients presents as a viable therapeutic option. Methods: Using hormone-sensitive breast cancer cells stably transfected with the aromatase gene (MCF-7/AC-1), works presented herein describe the in vitro and in vivo antitumor efficacy of the following compounds: dalotuzumab (DALO; âMK-0646â; anti-IGF-1R antibody), ridaforolimus (RIDA; âMK-8669â; mTORC1 small molecule inhibitor) and letrozole (âLETâ, aromatase inhibitor). Results: With the exception of MK-0646, all single agent and combination treatment arms effectively inhibited xenograft tumor growth, albeit to varying degrees. Correlative tissue analyses revealed MK-0646 alone and in combination with LET induced insulin receptor alpha A (InsR-A) isoform upregulation (both mRNA and protein expression), thereby further supporting a triple therapy approach. Conclusion: These data provide preclinical rationalization towards the combined triple therapy of LET plus MK-0646 plus MK-8669 as an efficacious anti-tumor strategy for ER-positive breast tumors. 46 samples, 28 days post treatment

Project description:High ploidy large cytoplasmic megakaryocytes (LCM) are critical negative regulators of hematopoietic stem cells (HSC) and are responsible for platelet formation. Using a mouse knockout model with normal megakaryocyte numbers but essentially devoid of LCM (MK-LCM KO), we demonstrated a pronounced increase in bone marrow HSC concurrent with endogenous mobilization and extramedullary hematopoiesis. When HSC isolated from a MK-LCM KO microenvironment were transplanted in lethally irradiated mice, the absence of LCM increased HSC in BM, blood and spleen. Severe thrombocytopenia was observed in animals with diminished LCM, although there was no change in megakaryocyte ploidy distribution. In contrast, WT HSC-generated LCM regulated a normal HSC pool and prevented thrombocytopenia. The present label-free quantitative LC-MSMS data was used to determine proteins that are differentially expressed in bone marrow cells of MK-LCM WT versus MK-LCM KO mice.
