Preclinical Evaluation of a Modified Herpes Simplex Virus Type 1 Vector Encoding Human TGM1 for the Treatment of Autosomal Recessive Congenital Ichthyosis

Q1 · MEDICINE

Article

Author: Krishnan, Suma ; Yogesha, S D ; Freedman, John C ; Parry, Trevor J ; Zhang, Peipei ; Majumdar, Avijit ; Ramasamy, Sureshkumar ; O'Malley, Mark ; Agarwal, Pooja ; Regula, Lauren K ; Coghlan, Sarah

Autosomal recessive congenital ichthyosis (ARCI) is a diverse group of cornification diseases associated with severe clinical complications and decreased quality of life. Germline mutations in the TGM1 gene, which encodes the enzyme TGM1, are the predominant cause of ARCI. These TGM1 mutations trigger the abnormal epidermal differentiation and impaired cutaneous barrier function observed in patients with ARCI. Unfortunately, current ARCI therapies focus solely on symptomatic relief. Thus, there is a significant unmet need for therapeutic strategies aimed at correcting the TGM1 deficiency underlying ARCI. In this study, we investigated the ability of KB105, a gene therapy vector encoding full-length human TGM1, to deliver functional human TGM1 to keratinocytes. In vitro, KB105 efficiently infected TGM1-deficient human keratinocytes, produced TGM1 protein, and rescued transglutaminase enzyme function. In vivo studies demonstrated that both single and repeated topical KB105 administration induced TGM1 protein expression in the target epidermal layer without triggering fibrosis, necrosis, or acute inflammation. Toxicity and biodistribution assessments on repeat dosing indicated that KB105 was well-tolerated and restricted to the dose site. Overall, our results demonstrate that rescuing TGM1 deficiency in patients with ARCI through topical KB105 application represents a promising strategy for safely and noninvasively treating this debilitating disease.

Thrombospondin-1 Is a Major Activator of TGF-β Signaling in Recessive Dystrophic Epidermolysis Bullosa Fibroblasts

Q1 · MEDICINE

Article

Mutations in the gene encoding collagen VII cause the devastating blistering disease recessive dystrophic epidermolysis bullosa (RDEB). RDEB is characterized by severe skin fragility and nonhealing wounds aggravated by scarring and fibrosis. We previously showed that TSP1 is increased in RDEB fibroblasts. Because transforming growth factor-β (TGF-β) signaling is also increased in RDEB, and TSP1 is known to activate TGF-β, we investigated the role of TSP1 in TGF-β signaling in RDEB patient cells. Knockdown of TSP1 reduced phosphorylation of smad3 (a downstream target of TGF-β signaling) in RDEB primary fibroblasts, whereas overexpression of collagen VII reduced phosphorylation of smad3. Furthermore, inhibition of TSP1 binding to the LAP/TGF-β complex decreased fibrosis in engineered extracellular matrix formed by RDEB fibroblasts, as evaluated by picrosirius red staining and analyses of birefringent collagen fibrillar deposits. We show that collagen VII binds TSP1, which could potentially limit TSP1-LAP association and subsequent TGF-β activation. Our study suggests a previously unreported mechanism for increased TGF-β signaling in the absence of collagen VII in RDEB patient skin. Moreover, these data identify TSP1 as a possible target for reducing fibrosis in the tumor-promoting dermal microenvironment of RDEB patients.

Transmission of viable Haemophilus ducreyi by Musca domestica

Article

Author: Donlan, Rachel A ; McCandless, Kayla ; Humphreys, Tricia L ; Gaston, Jordan R ; Stabile, Haley D

Haemophilus ducreyi was historically known as the causative agent of chancroid, a sexually-transmitted disease causing painful genital ulcers endemic in many low/middle-income nations. In recent years the species has been implicated as the causative agent of nongenital cutaneous ulcers affecting children of the South Pacific Islands and West African countries. Much is still unknown about the mechanism of H. ducreyi transmission in these areas, and recent studies have identified local insect species, namely flies, as potential transmission vectors. H. ducreyi DNA has been detected on the surface and in homogenates of fly species sampled from Lihir Island, Papua New Guinea. The current study develops a model system using Musca domestica, the common house fly, as a model organism to demonstrate proof of concept that flies are a potential vector for the transmission of viable H. ducreyi. Utilizing a green fluorescent protein (GFP)-tagged strain of H. ducreyi and three separate exposure methods, we detected the transmission of viable H. ducreyi by 86.11% ± 22.53% of flies sampled. Additionally, the duration of H. ducreyi viability was found to be directly related to the bacterial concentration, and transmission of H. ducreyi was largely undetectable within one hour of initial exposure. Push testing, Gram staining, and PCR were used to confirm the identity and presence of GFP colonies as H. ducreyi. This study confirms that flies are capable of mechanically transmitting viable H. ducreyi, illuminating the importance of investigating insects as vectors of cutaneous ulcerative diseases.

Ipsen sells priority review voucher for highest price since 2016

Ipsen Pharmaceuticals sold its priority review voucher to an unidentified “large global pharmaceutical company” for $158 million, it said this week, the highest publicly announced price for one of the vouchers in about eight years. Ipsen obtained the rare pediatric disease voucher in August 2023 thanks to the approval of Sohonos (palovarotene), which is intended to help adults and children with the rare disease known as fibrodysplasia ossificans progressiva. Priority review vouchers, or PRVs, can be acquired through the approval of rare pediatric disease or rare tropical disease drugs, and then can be sold or used by companies to speed the FDA’s reviews of any new drug. The $158 million sale is about $50 million more than any of the other PRV sales since last August, which includes sales of between $100 million and $108 million for Krystal Biotech, Valneva, X4 Pharmaceuticals and Day One Biopharmaceuticals. The last time a PRV sold for more than $158 million was in 2016, when PaxVax Bermuda sold its PRV, acquired via the approval of its cholera vaccine Vaxchora, for $290 million to an undisclosed buyer. PRVs have typically sold for about $100 million since the voucher programs began more than a decade ago, with higher prices of more than $150 million only coming between 2014 and 2016. “The sale of the PRV generates further firepower for our ongoing medicine launches and external-innovation strategy, which has seen multiple additions to our portfolio at every stage of development in 2024,” Philippe Lopes-Fernandes, chief business officer at Ipsen, said in a statement.
