Effects of Switching from Etelcalcetide to Upacicalcet in Patients on Hemodialysis with Secondary Hyperparathyroidism (KIDNEY WEEK 2025) - "Serum levels of corrected calcium (Ca), phosphorus (P), intact parathyroid hormone (iPTH), and the dose of maxacalcitol were assessed at three and six months after switching to upacicalcet. Multiple regression analysis revealed that the change in iPTH was related to the change in P levels. Conclusion These findings suggested that upacicalcet may be a useful option for managing serum P levels in hemodialysis patients with SHPT."

Combined Maxacalcitol/Betamethasone Butyrate Propionate Ointment Possesses Long-Term Sustained Effects of Inducing Regulatory T Cells and Downregulating the Th17 Response, Even After Discontinuation of Its Application in Imiquimod-Induced Psoriasiform Dermatitis. (PubMed, J Dermatol) - "In conclusion, MCT and MCT/BBP showed long-term effects by induction of regulatory T cells and IL-10. Additionally, MCT/BBP downregulated Th17-related cytokines, which could contribute to the sustained improvement after discontinuation observed in clinical practice."

Maxacalcitol alleviates diabetes-associated periodontitis in male mice by restoring Treg/Th17 balance via SOCE-mediated mitochondrial dysfunction. (PubMed, J Periodontol) - "Periodontitis, an inflammatory condition causing bone loss around teeth, is often more severe in individuals with diabetes due to immune system dysfunction. Specifically, diabetes-associated periodontitis (DPD) involves an imbalance between two types of immune cells: regulatory T cells (Treg), which control inflammation, and T helper 17 cells (Th17), which promote inflammation. This study explored how maxacalcitol (1α,25-dihydroxy-22-oxacalcitriol, OCT), a synthetic analog of active vitamin D3, treats DPD by correcting this immune cell imbalance. Using mouse models of DPD, we found that OCT significantly reduced bone loss and restored the balance between Treg and Th17 cells. Further investigation demonstrated that OCT functions by controlling calcium (Ca2⁺) entry into cells, thereby preserving mitochondrial health. Blocking excessive Ca2⁺ entry confirmed the improvement in immune cell balance. Conversely, increased Ca2⁺ influx or disrupted mitochondrial function negated..."

The Vitamin D Receptor-BIM Axis Overcomes Cisplatin Resistance in Head and Neck Cancer. (PubMed, Cancers (Basel)) - "Similar results were obtained for the clinically used VitD analog Maxacalcitol. Collectively, by identifying, for the first time, the VDR/BIM axis, we here provide a molecular rationale for the reported anti-cancer activity of VitD/analogs in combination therapies. Our data also suggest its exploitation as a potential strategy to overcome cisplatin resistance in HNSCC and other malignancies by inducing additional pro-apoptotic pathways."

Efficacy and Safety of Topical Treatments for Seborrheic Keratoses: A Systematic Review. (PubMed, J Dermatolog Treat) - "Topical treatments that yielded a good-to-excellent response include hydrogen peroxide, Maxacalcitol 25µg/g, BID Tazarotene 0.1% cream, 5% potassium dobesilate cream, 1% diclofenac sodium solution, urea-based solution, and 65% and 80% trichloroacetic acid. Topical hydrogen peroxide shows the greatest evidence for clinical clearance of seborrheic keratoses and may be a viable option for patients requesting non-invasive removal. No studies to our knowledge directly compare hydrogen peroxide to current first-line treatments.Meaning: There remains demand for topical treatments that reliably equate or exceed the efficacy of current first-line therapies."

Interventions for chronic palmoplantar pustulosis. (PubMed, Cochrane Database Syst Rev) - "Evidence is lacking for major chronic palmoplantar pustulosis treatments such as superpotent corticosteroids, phototherapy, acitretin, methotrexate, and ciclosporin. Risk of bias and imprecision limit our confidence. Maxacalcitol may be more effective than placebo in achieving clearance in the short term (low-quality evidence), and the risk of adverse effects is probably similar (moderate-quality evidence). Oral alitretinoin is probably no more effective than placebo in reducing severity, with a similar risk of adverse effects (moderate-quality evidence). Regarding biological treatments, we are uncertain of the effect of etanercept on clearance and the effect of ustekinumab on severity (low-quality evidence). Secukinumab and guselkumab are probably superior to placebo in reducing severity (moderate-quality evidence). Adverse events not requiring withdrawal were not reported for these treatments. Reporting of serious adverse effects was incomplete: compared to placebo,..."

Early Response of the Parathyroid Gland to Withdrawal of a Calcimimetic Compound in Uremic Rats. (PubMed, Am J Physiol Renal Physiol) - "We examined the response of parathyroid glands to cinacalcet (Cina) withdrawal in uremic Sprague-Dawley rats fed a high-phosphate diet to develop secondary hyperparathyroidism and divided into groups treated with vehicle (UC), Cina, and Cina and maxacalcitol (Maxa), a vitamin D receptor activator (CiNa + Maxa). Continuous administration of cinacalcet may be necessary for better control of SHPT. Simultaneous use of a VDRA may be preferable in the timing of cinacalcet withdrawal."

Vitamin D and Its Analogues Decrease Amyloid-β (Aβ) Formation and Increase Aβ-Degradation. (PubMed, Int J Mol Sci) - "Here we systematically investigate the effect of vitamin D and therapeutically used analogues (maxacalcitol, calcipotriol, alfacalcidol, paricalcitol, doxercalciferol) on AD-relevant mechanisms. Vitamin D and analogues decreased β-secretase activity, not only in mouse brains with mild vitamin D hypovitaminosis, but also in non-deficient mouse brains. Our results further strengthen the link between AD and vitamin D, suggesting that supplementation of vitamin D or vitamin D analogues might have beneficial effects in AD prevention."
