eGFR trajectories after transition from rhPTH(1-84) to palopegteriparatide in chronic hypoparathyroidism: a clinical practice cohort (ERA 2026) - "Importantly, patients with baseline CKD showed an increase in eGFR after transition to Palopegteriparatide, while non-CKD patients maintained stable eGFR. In rhPTH(1-84) -exposed patients, Palopegteriparatide was associated with further optimization of mineral management—near-complete withdrawal of conventional supplementation and additional phosphate improvement—suggesting incremental therapeutic benefit beyond rhPTH(1-84) in selected patients."

Intratrabecular bone remodeling - a previously overlooked mode of remodeling hyperactivated by parathyroid hormone. (PubMed, J Bone Miner Res) - "This study primarily utilizes iliac crest bone biopsies collected from a clinical trial where patients with hypoparathyroidism were randomized to receive daily injections with either 100μg rhPTH(1-84) or placebo as add-on to conventional therapy for 6 months...Intratrabecular remodeling parameters showed a positive correlation with PTH-induced trabecular mineralization and a negative correlation with active vitamin D-supplementary doses. Dynamics of the PTH-induced intratrabecular remodeling could be tracked using time-lapsed synchrotron radiation μCT in a rabbit model and the complexity of the trabecular strain environment was confirmed with micro-finite-element analysis."

Preliminary Results from a Prospective Cohort Study on Real-World Data of Chronic Hypoparathyroidism Treated with Trans-Con PTH (ESPE-ESE 2025) - "Background: Chronic hypoparathyroidism (HypoPT) is a rare endocrine disorder characterized by deficient parathyroid hormone (PTH) levels, leading to hypocalcemia and dependency on calcium and active vitamin D., Trans-conPTH 1-34 formulation (Yorvipath), has emerged as a potential therapeutic option for patients with uncontrolled hypoparathyroidism or those previously treated with rhPTH(1-84)...Additionally, 15 patients (40%) were on hydrochlorothiazide for hypercalciuria... Preliminary findings suggest that Yorvipath is effective in reducing or eliminating the need for calcium and activated vitamin-D treatment in patients with HypoPT. Most patients achieved Ca/active VitD independence within the first few weeks of treatment. Further studies with longer follow-up are warranted to confirm the long-term efficacy and safety of Yorvipath in this patient population."

Palopegteriparatide for the treatment of Autosomal Dominant Hypocalcemia type 1 (ADH1) (ESPE-ESE 2025) - "He was treated with calcium carbonate 500mg 1x2, alfacalcidol 1 mcg 1x1, cholecalciferol 800UI 1x1, hydrochlorothiazide 25mg 1x1, rhPTH (Natpar) 75-100 mcg 1x1 and magnesium supplements. He also received dasatinib for the CML... Until the launch of the calcilytics, palopegteriparatide (Yorvipath) may represent a valuable alternative for the management of ADH1."
