NEW YORK, July 31, 2020 /PRNewswire/ -- Hoth Therapeutics, Inc. (NASDAQ: HOTH), a biopharmaceutical company, today announced it has executed a licensing agreement with Isoprene Pharmaceuticals, Inc. to acquire the rights to VNLG-152, a novel retinamides (Retinoic acid metabolism blocking agents, or RAMBAs) for the treatment of dermatological diseases. Isoprene is a cancer therapeutic company that is a University of Maryland, Baltimore New Venture Initiative start-up.
This agreement, which formalizes the previously announced Letter of Intent between the two companies, will also grant Hoth royalty payments from Isoprene for any use of its VNLG-152 including Oncology.
Researchers at the University of Maryland Baltimore discovered novel retinamide RAMBAs and validated their therapeutic utility in animal models of breast and prostate cancer. RAMBAs inhibit the cellular enzyme that metabolizes all-trans retinoic acid (ATRA), which actively directs cells to mature in a controlled manner to ensure normal growth.
In addition to enhancing the beneficial effects of ATRA, the mechanism of action for these RAMBAs has been shown to involve degradation of Mnk 1/2 and suppression of the oncogenic eIF4E pathway. For potential use in treating dermatological conditions, UMB researchers obtained promising early results demonstrating that lead retinamide RAMBAs have equal or superior effects over approved retinoids (ATRA and 13-CRA) to inhibit proliferation of normal human adult keratinocytes and sebocytes, and antikeratinizing effects in reconstructed human epidermis. Initial toxicity profiles for a panel of RAMBAs [Njar et al., 2006] also showed good indications for safe therapeutic use.
These novel RAMBAs block the normal metabolism of endogenous ATRA in cells, increasing the beneficial effects of ATRA. They provide a unique approach to achieve the therapeutic benefit of retinoid therapy while potentially circumventing the adverse events associated with it, a very important property for application to dermatology therapy. ATRA deficiencies are associated with dermatological diseases (acne and psoriasis), and retinoid derivatives have been one of the mainstay therapies for acne. Liarozole is in clinical use for the treatment of psoriasis and ichthyosis. Dermatological retinoid deficiencies are characterized by hyperkeratinization and desquamation and include diseases such as acne, eczema, psoriasis, cold sores, wounds, burns, sunburn, ichthyosis, skin cancer, and Kaposi's Sarcoma, all of which are plausible targets for retinamide RAMBA therapy.
Mr. Robb Knie, Chief Executive Officer of Hoth, commented, "Hoth is pleased to finalize this licensing agreement of a novel therapy that has shown such promise in targeting such a wide array of dermatological afflictions. This latest license agreement reinforces Hoth's commitment to developing novel therapies for multiple skin diseases."
