Partial RAG deficiency (pRD) can manifest with systemic and tissue-specific immune dysregulation, with inflammatory bowel disease (IBD) in 15% of the patients. We aimed at identifying the immunopathological and microbial signatures associated with IBD in patients with pRD and in a mouse model of pRD (Rag1w/w) with spontaneous development of colitis. pRD patients with IBD and Rag1w/w mice showed a systemic and colonic Th1/Th17 inflammatory signature. Restriction of fecal microbial diversity, abundance of pathogenic bacteria, and depletion of microbial species producing short-chain fatty acid were observed, which were associated with impaired induction of lamina propria peripheral Treg cells in Rag1w/w mice. The use of vedolizumab in Rag1w/w mice and of ustekinumab in a pRD patient were ineffective. Antibiotics ameliorated gut inflammation in Rag1w/w mice, but only bone marrow transplantation (BMT) rescued the immunopathological and microbial signatures. Our findings shed new light in the pathophysiology of gut inflammation in pRD and establish a curative role for BMT to resolve the disease phenotype.

Activity and structure of human (d)CTP deaminase CDADC1

Article

Author: Slyvka, Anton ; Rathore, Ishan ; Skowronek, Krzysztof ; Kanai, Tapan ; Bochtler, Matthias ; Gewartowska, Olga ; Wlodawer, Alexander ; Yang, Renbin ; Lountos, George T. ; Czarnocki-Cieciura, Mariusz

Vertebrates have evolved an understudied protein termed CDADC1 (NYD-SP15) that contains an inactive N-terminal and active C-terminal DCTD-like domain. Here, we show that human CDADC1 is a (d)CTP-specific deaminase, with a roughly 2-fold in vitro preference for dCTP over CTP. We determined high-resolution cryo-EM structures of CDADC1 in the absence of substrate and in complex with dCTP and 5-methyl-dCTP. The structures show that CDADC1 forms trimers and dimers of trimers in solution. The (d)CTP substrate is selected by a narrow pocket for the cytosine base and multiple lysine and arginine contacts to the triphosphate. Substrate binding promotes the association of trimers into hexamers and the transition of the hexamers from a loose to a tighter arrangement. Genetic experiments in mice show that loss of Cdadc1 is surprisingly well tolerated, even in the absence of the dCMP deaminase Dctd that is considered as the main source of dUMP, the precursor of dTTP.

Treatment of Cutaneous Neurofibromas in Neurofibromatosis Type 1 With MEK Inhibitor Selumetinib

Article

Author: Steinberg, Seth M. ; Choo-Wosoba, Hyoyoung ; Pichard, Dominique C. ; Gross, Andrea M. ; Baldwin, Lauren A. ; Widemann, Brigitte C. ; Wolters, Pamela L. ; Dombi, Eva ; Cannon, Ashley ; Derdak, Joanne ; Reid, Olivia H. ; Korf, Bruce R. ; Tibery, Cecilia M. ; Lobbous, Mina

Importance:

Cutaneous neurofibromas (cNFs) can cause itching, disfigurement, pain, and emotional difficulties in people with neurofibromatosis type 1 (NF1).

Objective:

To determine the impact of the mitogen-activated protein kinase kinase inhibitor selumetinib on cNF including change in tumor volume and patient-reported outcome measures.

Design, Setting, and Participants:

Adults with NF1 and 9 or more measurable cNFs were enrolled in this nonrandomized pilot trial at the National Cancer Institute and the University of Alabama at Birmingham, which spanned from August 26, 2017, to August 21, 2023.

Intervention:

Participants received selumetinib for up to 24 cycles (1 cycle = 28 days) with restaging visits after every 4 cycles.

Main Outcomes and Measures:

Photography and volumetric measurements of cNFs using calipers were used to evaluate the number and volume of tumors. Participants completed the Skindex-29 Quality of Life assessment to quantify the effect of treatment on symptoms, functioning, emotions, itching, and pain.

Results:

Among the 11 participants who enrolled, the median (range) age was 54 (28-75) years, and 6 were female. The median (IQR) best response across all participants and tumors was a −28.5% (−40.9% to −12.5%) decrease in cNF volume from baseline. Some participants showed a visible improvement in cNF burden while receiving treatment in standardized photographs. The median (range) duration of treatment was 9 cycles (1-24), with only 4 participants completing the full 24 cycles of treatment. Two of these participants continued treatment beyond the original 24 cycles due to perceived clinical benefit. All participants experienced at least 1 reversible drug-related adverse event (AE), with cutaneous AEs such as dry skin and rash being the most common. Two participants were removed from treatment due to concern for drug reaction with eosinophilia and systemic symptoms. While the Skindex-29 assessment showed improvement in emotion scores after cycle 1, there were no other significant or durable changes in scores.

Conclusions and Relevance:

In this nonrandomized pilot trial, selumetinib resulted in some decrease in cNF volume; however, there was no sustained improvement in patient-reported outcome measures. Study enrollment was incomplete, in part due to the COVID-19 pandemic, and highlights the challenges of treating patients with cNF with a drug that often leads to dermatologic AEs. Future larger studies using other measurement techniques, such as 3-dimensional photography, could help to yield results that are more generalizable to the phenotypically diverse NF1 population.

BridgeBio Spins Out Oncology Company with $200M in Financing

Pictured: 3D image of a KRAS oncogene iStock/Gilnature BridgeBio announced Thursday that it has secured $200 million in financing to spinout a former subsidiary to develop a KRAS-focused oncology portfolio. Called BridgeBio Oncology Therapeutics (BBOT), the company was initially formed as a subsidiary of BridgeBio known as TheRas. According to an SEC filing, the subsidiary has existed since 2016 and formed a research and development agreement with Leidos Biomedical Research in 2017. BBOT’s mission now is to generate a pipeline of small molecule therapeutics targeting RAS and PI3K malignancies. The company aims to advance three programs, including BBO-8520, a direct inhibitor of KRAS that seeks to bind to the protein’s “on” and “off” states. The spinout is enrolling patients with mutant non-small cell lung cancer in a Phase Ia/Ib trial. A second asset that BBOT will be advancing is BBO-10203, a PI3Kα:RAS breaker that blocks the interaction between RAS and PI3Ka to inhibit the PI3Kα/AKT effector signaling in tumors. The company plans to IND application sometime in the second quarter of 2024 and enroll patients later this year. The other asset is BBO-11818, a pan-KRAS inhibitor that is going after the “on” and “off” states of KRASG12X, and BBOT plans to IND sometime in early 2025. The company is also pursuing a discovery-stage research program focused on developing assets that target additional oncogenic drivers within the RAS and PI3K pathways. “We believe the launch of BBOT better aligns investors with an opportunity that was being hidden in our pipeline, and our partnership with these new investors enables us to prosecute these oncology programs more quickly and with higher fidelity,” BridgeBio CEO Neil Kumar said in a statement. The spinout secured its $200 million financing in an oversubscribed round led by Cormorant Asset Management and co-led by Omega Funds. There was also participation from GV (Google Ventures), Deerfield Management, EcoR1 Capital, Wellington Management, Enavate Sciences, Surveyor Capital, Casdin Captial, Aisling Capital, and Longwood Fund. BBOT will headed by Eli Wallace, BridgeBio’s CEO of oncology R&D. Wallace joined BridgeBio in 2019 after serving as the chief scientific officer at Peloton Therapeutics. Kumar will also serve as a director of BBOT. “In conjunction with BridgeBio and an amazing suite of investors, we look forward to seeing all three of our programs progress into the clinic over the next 12 months,” Wallace said in a statement. BridgeBio has gone down the spinout path before, launching QED Therapeutics in 2018. The company secured $65 million and aimed to develop infigratinib, a cancer asset that Novartis abandoned. Infigratinib was given accelerated approval by the FDA in 2021. Tyler Patchen is a staff writer at BioSpace. You can reach him at tyler.patchen@biospace.com. Follow him on LinkedIn.
