Adverse effects

The US Food and Drug Administration (FDA) prescription label for palopegteriparatide includes warnings for a potential risk of risk of unintended changes in serum calcium levels related to number of daily injections and total delivered dose, serious hypocalcemia and hypercalcemia (blood calcium levels that are too high), osteosarcoma (a rare bone cancer) based on findings in rats, orthostatic hypotension (dizziness when standing), and a risk of a drug interaction with digoxin (a medicine for certain heart conditions).^[5]

History

The effectiveness of palopegteriparatide was evaluated in a 26-week, randomized, double-blind, placebo-controlled trial that enrolled 82 adults with hypoparathyroidism.^[5] 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 to 80 ng/mL.^[5] 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).^[5] Study drug and conventional therapy were subsequently adjusted according to the albumin-corrected serum calcium levels.^[5] 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).^[5]

The FDA granted the application for palopegteriparatide orphan drug and priority review designations.^[5]
