A new study suggests that adding common bone loss drugs to azoles can improve efficacy when treating fungal infections. Human skin, hair and nails are all vulnerable to fungal infections. While these infections are usually not serious, they're difficult to fully resolve and often recur after treatment -- sometimes for years. They're also often resistant to treatments, including a common class of antifungals called azoles. A study published this week in mSphere points to a new way to boost the efficacy of azoles in treating those infections -- combining them with commonly available drugs called bisphosphonates, usually used to treat osteoporosis. Previous work by the same research group has shown that adding bisphosphonates to azoles can effectively treat yeast infections from Candida and Cryptococcus species. The new study extends that finding to dermatophytes, which cause superficial infections. The study suggests that bisphosphonates could be repurposed to use with azole antifungals, which are relatively nontoxic, and that the combination could be readily tested in clinical studies. "There aren't many good antifungal drugs around, and the fungus will always develop resistance no matter how you treat them," said senior author Dee Carter, a mycologist at the University of New South Wales, Australia. "For what we're proposing, to use 2 drugs at the same time, that resistance is much less likely." Carter says she was only a little surprised to see the synergistic effect in dermatophytes. This research project began years ago, she says, when her group conducted a series of genomic analyses on the response of pathogenic yeasts to drug treatment. That study led them to a genetic pathway that is "upstream" of the pathway targeted by azoles, and is instead targeted by bisphosphonates. "That's often a good way to get drugs to work, is to target processes that are interlinked like that," Carter said. In the lab, Carter and her team tested 3 commonly available bisphosphonates (risedronate, alendronate and zoledronate) in combination with 3 commonly available azole antifungals (fluconazole, itraconazole and ketoconazole). They tested these against clinical isolates from a diverse range of dermatophyte species that cause superficial infections. The combination of zoledronate and ketoconazole proved particularly effective against 8 of the 9 tested species. It also prevented the development of resistance. Aidan Kane, mycologist, lead author of the study and a Ph.D. student in Carter's lab, used fluorescence microscopy and other methods to show that the drug combination worked by weakening the cell membrane enough that the fungus could not survive. Beyond the dermatophytes, the group also found that bisphosphonate-azole combinations could act against molds that cause invasive disease, suggesting another possible clinical application for the drugs. "You can use these combinations directly for superficial infections, like Candida or dermatophyte infections, and we're hoping that with modified forms of the drugs we can create something that will also work systematically," Carter said. "The next step is to continue testing bisphosphonate-azole combinations in animal models, and then test it in clinical trials."

TYMLOS®demonstrated a lower incidence of hip fracture and non-vertebral fracture compared to teriparatide in women with osteoporosis 50 years and older (n=43,352) in this analysis of real-world data BOSTON, MA / ACCESSWIRE / April 16, 2024 / Radius Pharmaceuticals, Inc., a wholly owned subsidiary of Radius Health, Inc. ("Radius" or the "Company"), a specialty biopharmaceutical company focused on bone health, presented real-world evidence from an analysis comparing the effectiveness of TYMLOS® (ABL) to teriparatide (TPTD) in women with osteoporosis ages 50 years and older who were new to anabolic therapy (n=43,352). In this analysis of over 18-months of treatment, abaloparatide demonstrated a lower incidence of hip fracture and non-vertebral fracture compared to teriparatide. Hip fractures were reported in 1.1% of women in the ABL cohort and 1.4% of women in the TPTD cohort (HR [95% CI] 0.83 [0.70, 0.98]; P=0.03). Nonvertebral fractures were reported in 4.4% of women in the ABL cohort and 5.0% of women in the TPTD cohort (0.88 [0.80, 0.96]; P=0.003). Major cardiovascular events were balanced between cohorts.1 "The real-world data presented further supports the favorable efficacy and safety pro TYMLOS and why it is an important treatment option in the management of osteoporosis," said Dr. Felicia Cosman, Professor of Medicine at Columbia University College of Physicians and Surgeons in New York, NY, an osteoporosis specialist and clinical scientist and Co-Editor in Chief of the Journal Osteoporosis International. "Harnessing real-world evidence from everyday clinical settings affords clinicians the opportunity to uncover insights that can help guide treatment decisions." The data was presented in an abstract and oral presentation at the 24th Edition of the World Congress on Osteoporosis, Osteoarthritis and Musculoskeletal Diseases (WCO-IOF-ESCEO) in London, on April 12th, 2024. This real-world retrospective observational cohort study identified women 50 years and older, newly initiated on anabolic therapy with ABL or TPTD between May 1, 2017, and Dec 31, 2021.This analysis included pre-specified outcomes and utilized propensity score matching to help balance the characteristics in each treatment group; patients were well matched on 73 baseline parameters.1 Patients were identified using anonymized claims data from the Symphony Health Patient Source, Osteoporosis Patient Transactional Datasets. This is a disease specific subset of Integrated Dataverse® which includes data from over 307 million active patients. "We are very pleased to share the results of this analysis, as it further demonstrates the value of TYMLOS in the treatment of women with osteoporosis," said Scott Briggs, Chief Executive Officer of Radius. "Radius is committed to supporting men and postmenopausal women with osteoporosis, their families, and healthcare providers through our ongoing educational efforts as well as by generating data to support informed healthcare decision making." Real World Evidence: It is important to consider the limitations of RWE. RWE data sources may have incomplete information, leading to challenges in identifying and characterizing specific populations accurately. The source and type of RWE may limit the generalizability of the endpoints to broader populations/settings. RWE should be used in supplement to clinical trial evidence to support healthcare decision making. Due to data limitations, mortality data was not available in this dataset. There are no head-to-head randomized controlled clinical trials comparing abaloparatide and teriparatide. INDICATONS and IMPORTANT SAFETY INFORMATION INDICATIONS TYMLOS is indicated for: the treatment of postmenopausal women with osteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy. In postmenopausal women with osteoporosis, TYMLOS reduces the risk of vertebral fractures and nonvertebral fractures, and the treatment to increase bone density in men withosteoporosis at high risk for fracture (defined as a history of osteoporotic fracture or multiple risk factors for fracture), or patients who have failed or are intolerant to other available osteoporosis therapy. IMPORTANT SAFETY INFORMATION2 Contraindications: TYMLOSis contraindicated in patients with a history of systemic hypersensitivity to abaloparatide or to any component of the product formulation. Reactions have included anaphylaxis, dyspnea, and urticaria. Risk of Osteosarcoma: It is unknown whether TYMLOS will cause osteosarcoma in humans. Osteosarcoma has been reported in patients treated with a PTH-analog in the post marketing setting; however, an increased risk of osteosarcoma has not been observed in observational studies in humans. There are limited data assessing the risk of osteosarcoma beyond 2 years of TYMLOS use. Avoid use of TYMLOS for patients at an increased baseline risk for osteosarcoma including patients with open epiphysis (pediatric and young adult patients); metabolic bone diseases other than osteoporosis, including Paget's disease of the bone; bone metastases or a history of skeletal malignancies; prior external beam or implant radiation therapy involving the skeleton; or hereditary disorders predisposing to osteosarcoma. Orthostatic Hypotension: Orthostatic hypotension may occur with TYMLOS, typically within 4 hours of injection. Associated symptoms may include dizziness, palpitations, tachycardia, or nausea, and may resolve by having the patient lie down. For the first several doses, TYMLOS should be administered where the patient can sit or lie down if necessary. Hypercalcemia: TYMLOSmay cause hypercalcemia. TYMLOS is not recommended in patients with pre-existing hypercalcemia or in patients who have an underlying hypercalcemic disorder, such as primary hyperparathyroidism, because of the possibility of exacerbating hypercalcemia. Hypercalciuria and Urolithiasis: TYMLOSmay cause hypercalciuria. It is unknown whether TYMLOS may exacerbate urolithiasis in patients with active or a history of urolithiasis. If active urolithiasis or pre-existing hypercalciuria is suspected, measurement of urinary calcium excretion should be considered. Pregnancy and Lactation: TYMLOSis not indicated for use in females of reproductive potential. Adverse Reactions: The most common adverse reactions (incidence ≥2%) reported with TYMLOS in postmenopausal women with osteoporosis are hypercalciuria (11%), dizziness (10%), nausea (8%), headache (8%), palpitations (5%), fatigue (3%), upper abdominal pain (3%), and vertigo (2%). The most common adverse reactions (incidence ≥2%) reported with TYMLOS in men with osteoporosis are injection site erythema (13%), dizziness (9%), arthralgia (7%), injection site swelling (7%), injection site pain (6%), contusion (3%), abdominal distention (3%), diarrhea (3%), nausea (3%), abdominal pain (2%), and bone pain (2%).
