History

Perspective
The effectiveness of palopegteriparatide was evaluated in a 26-week, randomized, double-blind, placebo-controlled trial that enrolled 82 adults with hypoparathyroidism.[6] Prior to randomization, all participants underwent an approximate four-week screening period in which calcium and active vitamin D supplements were adjusted to achieve an albumin-corrected serum calcium concentration between 7.8 and 10.6 mg/dL, a magnesium concentration ≥1.3 mg/dL and below the upper limit of the reference range, and a 25(OH) vitamin D concentration between 20 and 80 ng/mL.[6] During the double-blind period, participants were randomized to either palopegteriparatide (N = 61) or placebo (N= 21), at a starting dose of 18 mcg/day, co-administered with conventional therapy (calcium and active vitamin D).[6] Study drug and conventional therapy were subsequently adjusted according to the albumin-corrected serum calcium levels.[6] At the end of the trial, 69% of the participants in the palopegteriparatide group compared to 5% of the participants in the placebo group were able to maintain their calcium level in the normal range, without needing active vitamin D and high doses of calcium (calcium dose ≤ 600 mg/day).[6]
The FDA granted the application for palopegteriparatide orphan drug and priority review designations.[6]
