Phase I/II Trial of BINTRAFUSP ALFA (M7824) and Pimasertib for Treatment of Intracranial Metastases

This phase I/II trial studies the best dose and effect of pimasertib in combination with bintrafusp alfa in treating patients with cancer that has spread to the brain (brain metastases). Immunotherapy with bintrafusp alfa, a bifunctional fusion protein composed of the monoclonal antibody anti-PD-L1 and TGF-beta, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Pimasertib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving pimasertib and bintrafusp alfa may help to prevent or delay the cancer from progressing (getting worse) and/or coming back.

Identification and Experimental Validation of NETosis-Mediated Abdominal Aortic Aneurysm Gene Signature Using Multi-omics, Machine Learning, and Mendelian Randomization

Article

Abdominal aortic aneurysm (AAA) is a life-threatening disorder with limited therapeutic options. Neutrophil extracellular traps (NETs) are formed by a process known as "NETosis" that has been implicated in AAA pathogenesis, yet the roles and prognostic significance of NET-related genes in AAA remain poorly understood. This study aimed to identify key AAA- and NET-related genes (AAA-NETs-RGs), elucidate their potential mechanisms in contributing to AAA, and explore potential therapeutic compounds for AAA therapy. Through bioinformatics analysis of multiomics and machine learning, we identified six AAA-NETs-RGs: DUSP26, FCN1, MTHFD2, GPRC5C, SEMA4A, and CCR7, which exhibited strong diagnostic potential for predicting AAA progression, were significantly enriched in pathways related to cytokine-cytokine receptor interaction and chemokine signaling. Immune infiltration analysis revealed a causal association between AAA-NETs-RGs and immune cell infiltration. Cell-cell communication analysis indicated that AAA-NETs-RGs predominantly function in smooth muscle cells, B cells, T cells, and NK cells, primarily through cytokine and chemokine signaling. Gene profiling revealed that CCR7 and MTHFD2 exhibited the most significant upregulation in AAA patients compared to non-AAA controls, as well as in in vitro AAA models. Notably, genetic depletion of CCR7 and MTHFD2 strongly inhibited Ang II-induced phenotypic switching, functional impairment, and senescence in vascular smooth muscle cells (VSMCs). Based on AAA-NETs-RGs, molecular docking analysis combined with the Connectivity Map (CMap) database identified mirdametinib as a potential therapeutic agent for AAA. Mirdametinib effectively alleviated Ang II-induced phenotypic switching, biological dysfunction, and senescence. These findings provide valuable insights into understanding the pathophysiology of AAA and highlight promising therapeutic strategies targeting AAA-NETs-RGs.

Preclinical Activity of the Type II RAF Inhibitor Tovorafenib in Tumor Models Harboring Either a BRAF Fusion or an NF1 Loss-of-Function Mutation

Article

Author: Venetsanakos, Eleni ; Perino, Samantha ; Wang, Yujin ; Lal-Nag, Madhu ; Rastogi, Shubhra ; Blackman, Samuel C.

Abstract:

Genomic alterations and dysregulation of the MAPK pathway have been described in many different types of cancers. BRAFV600 mutations and BRAF fusions, found in both pediatric and adult cancers, are oncogenic drivers that drive constitutive activation of the RAF pathway. Neurofibromin 1 (NF1) loss-of-function (LOF) mutations, which occur in many cancer types, result in decreased neurofibromin GAP function, thus activating RAS. Tovorafenib is an oral selective, central nervous system–penetrant, type II RAF inhibitor which inhibits RAF monomers and dimers. In this study, the impact of tovorafenib alone or in combination with MEK inhibitor, pimasertib, was explored in adult or pediatric tumor models harboring BRAF fusions or NF1-LOF mutations. Tovorafenib resulted in tumor regression in an AGK::BRAF fusion melanoma patient-derived xenograft model in vivo, while exhibiting little antitumor activity in NF1-LOF tumor models. In vitro anti-proliferative activity of tovorafenib and pathway modulation was evaluated in NF1-LOF tumor cell lines. Little anti-proliferative activity was observed in the NF1-LOF tumor cell lines treated with tovorafenib. In NF1-LOF tumor cells treated with tovorafenib, an increase in phosphorylated ERK was observed at low concentrations, with inhibition of phosphorylated ERK at higher concentrations. When tovorafenib was combined with pimasertib in vitro, synergy was observed in an NF1-LOF embryonal rhabdomyosarcoma patient-derived xenograft model ex vivo and an NF1-LOF Malignant peripheral nerve sheath tumors (MPNST) cell line in vitro, suggesting that vertical pathway inhibition is needed in the NF1-LOF mutant setting.

Significance::

Tovorafenib demonstrated efficacy in BRAF fusion but not in NF1-LOF mutant tumor models. Vertical pathway inhibition by combining type II RAF plus MEK inhibitors may have clinical relevance in NF1-LOF mutant tumors.

(Nasdaq: DAWN) (“Day One” or the “Company”), a biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, today announced its second quarter 2024 financial results and highlighted recent corporate achievements. “We had an outstanding quarter across all facets of our business,” said Jeremy Bender, Ph.D., chief executive officer of Day One. “Demand for OJEMDA led to strong early launch performance following our first approval, and we made significant progress advancing our programs and pipeline, including the addition of DAY301, a potential first-in-class ADC targeting PTK7 that we expect to be in the clinic in the coming months.” Program Highlights OJEMDA received U.S. Food and Drug Administration (FDA) accelerated approval in April 2024. It is the first and only FDA approved therapy for the treatment of patients 6 months of age and older with relapsed or refractory pediatric low-grade glioma (pLGG) harboring a BRAF fusion or rearrangement, or BRAF V600 mutation. Day One provided updated duration of treatment data from the registrational Phase 2 FIREFLY-1 trial investigating tovorafenib in patients with BRAF-altered, relapsed or progressive pLGG. For the 77 patients enrolled on Arm 1, which was the dataset used to assess OJEMDA’s efficacy, the median duration of treatment is now 23.7 months, with some patients being on treatment out to 32 months. Additional analyses will be presented at future medical conferences. Day One and Ipsen entered into an exclusive licensing agreement to commercialize tovorafenib outside of the U.S. in July 2024. Under the agreement, Day One will receive approximately $111 million upfront in cash and equity investment at a premium with up to approximately $350 million in additional launch and sales milestone payments as well as tiered double-digit royalties starting in mid-teens percentage on net sales. Ipsen secured commercialization rights to tovorafenib outside of the U.S. Day One entered into an exclusive licensing agreement with MabCare Therapeutics for its novel ADC targeting protein-tyrosine kinase 7 (PTK7) in June 2024. The Company expects to dose the first patient in the Phase I portion of the Phase 1/2a clinical trial of DAY301 in the fourth quarter of 2024 or first quarter of 2025.Day One presented a poster on tovorafenib demonstrating reversibility of changes in growth velocity observed in the Phase 2 FIREFLY-1 clinical trial at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting. These data were also shared at the 21st International Symposium on Pediatric Neuro-Oncology (ISPNO). Day One made the decision to close the pimasertib program in July 2024, including the FIRELIGHT-1 trial evaluating it in combination with tovorafenib. Resources will be redirected to the DAY301 program and results will be shared at a future medical meeting or publication. The pivotal Phase 3 FIREFLY-2/LOGGIC clinical trial evaluating tovorafenib as a front-line therapy in patients aged 6 months to 25 years with pLGG continues to enroll patients in the United States, Canada, Europe, Australia and Asia, with more than 100 sites activated. Corporate Highlights and Upcoming Milestones Day One announced it entered into a definitive agreement for an oversubscribed private placement of its securities for total gross proceeds of approximately $175.0 million in July 2024. The Company sold the rare pediatric disease Priority Review Voucher awarded by the FDA upon OJEMDA’s approval for total cash proceeds of $108.0 million in May 2024, representing a gain on sale.Commercial operations veteran John Stubenrauch joined Day One in July 2024 as Chief Technology Officer. Dr. Stubenrauch, PhD, MBA, was most recently Chief Operating Officer at Nutcracker Therapeutics and brings more than 25 years of experience developing and commercializing medicines, including ADCs, as well as a broad range of product modalities.

Day One inks PTK7-targeting ADC licensing deal with MabCare

Day One Biopharmaceuticals has announced an exclusive licensing agreement with MabCare Therapeutics for MTX-13, a novel antibody-drug conjugate (ADC) targeting protein-tyrosine kinase 7 (PTK7). Under the terms of the agreement, Shanghai-based MabCare will receive $55 million upfront and up to $1.152 billion in additional milestones, along with royalties on net sales outside Greater China. Day One aims to dose the first patient in a phase 1 study by late 2024 or early 2025. The compound, now designated as DAY301, received IND clearance from the FDA in April 2024. It targets PTK7, a transmembrane protein highly expressed in various solid tumors, including esophageal, ovarian, lung, and endometrial cancers in adults, as well as pediatric cancers such as neuroblastoma and osteosarcoma. Preclinical studies have shown that DAY301 has significant antitumor activity, making it a promising candidate for treating both adult and pediatric cancers. Day One Biopharmaceuticals, headquartered in Brisbane, California, focuses on developing targeted cancer therapies. The company’s pipeline includes recently approved tovorafenib (branded Ojemda) and pimasertib, currently in phase 1/2 trials. ADCs work by combining the targeting ability of antibodies with the potent cell-killing power of chemotherapy drugs. This allows for the direct delivery of toxic agents to cancer cells, minimizing damage to healthy cells and potentially reducing side effects compared to traditional chemotherapy. The ADC market is rapidly growing , with several ADCs already approved by regulatory agencies worldwide and many more in clinical development.

Day One Expands Pipeline with Potential First-in-Class Clinical-Stage Antibody Drug Conjugate (ADC) Targeting PTK7 in Solid Tumors for Adult and Pediatric Cancers

Day One receives exclusive license for development and commercialization of MTX-13 (DAY301), which received IND clearance by the FDA in April 2024 Targets PTK7, highly expressed in broad range of adult and pediatric solid tumors BRISBANE, Calif., June 18, 2024 (GLOBE NEWSWIRE) -- Day One Biopharmaceuticals (Nasdaq: DAWN) (“Day One” or the “Company”), a commercial-stage biopharmaceutical company dedicated to developing and commercializing targeted therapies for people of all ages with life-threatening diseases, today announced it has entered into an exclusive licensing agreement (the Agreement) with MabCare Therapeutics (MabCare) for MTX-13, a novel ADC targeting protein-tyrosine kinase 7 (PTK7). Pursuant to the terms of the Agreement, Day One has exclusive rights to develop, manufacture, and commercialize MTX-13 worldwide, excluding Greater China. In April 2024, the U.S. Food and Drug Administration (FDA) cleared the investigational new drug (IND) application for MTX-13, which going forward will be identified as DAY301. In pre-clinical studies, DAY301 showed antitumor activity in a wide range of solid tumors. “Our priorities for 2024 are to successfully launch OJEMDA™ (tovorafenib), to advance our existing programs and to expand our pipeline by in-licensing clinical-stage assets that have the potential to transform outcomes for patients of all ages living with cancers,” said Jeremy Bender, Ph.D., chief executive officer of Day One. “We are excited by the opportunity presented by DAY301, and we believe we have the right team in place to develop the program to its full potential.” DAY301 targets PTK7, a highly-conserved, catalytically inactive transmembrane protein that is overexpressed in multiple adult cancers, including esophageal, ovarian, lung, and endometrial cancer, as well as pediatric cancers such as neuroblastoma, rhabdomyosarcoma and osteosarcoma. PTK7 has limited expression in normal tissues or organs, making it an attractive target for therapeutic development. “The addition of DAY301 to our pipeline strategically fits our mission of advancing both pediatric and adult medicines in areas of unmet need with equal urgency,” said Dr. Samuel Blackman, co-founder and head of research and development at Day One. “We believe the linker-payload technology embodied in DAY301 will overcome the limitations of earlier PTK7-targeted ADCs, giving us a potential first-in-class drug against a clinically-validated target. We are excited to add this program to Day One and will look to enter the clinic in the coming months.” Under the terms of the licensing agreement, MabCare will receive $55 million upfront, and is eligible to receive an additional $1.152 billion in development, regulatory and commercial success-based milestones, plus low-to-mid single-digit royalties on net sales outside of Greater China. Day One expects the first patient to be dosed in the Phase I study in the fourth quarter of 2024 or first quarter of 2025.
