Skip to main content Results With YORVIPATH | YORVIPATH® (palopegteriparatide) Patient Site

YORVIPATH was assessed in a 26-week clinical study

82 adults with hypopara participated in the study
61 adults received YORVIPATH in study versus 21 adults received placebo in study 61 adults received YORVIPATH in study versus 21 adults received placebo in study
Dosing and dose adjustment protocol:
  • All participants were on conventional therapy, then were assigned to take either YORVIPATH or placebo
  • Doses for YORVIPATH, placebo, and conventional therapy were adjusted by a doctor based on blood calcium levels
*The placebo injection was meant to act like the YORVIPATH injection, but without any active substances.

The effectiveness of YORVIPATH was measured by a strict set of treatment criteria

To be considered responsive to treatment with YORVIPATH, people had to meet ALL of the following criteria at Week 26:
  • Normal blood calcium levels
  • Independence from conventional therapy since Week 22
  • No increase in YORVIPATH or placebo doses since Week 22
  • No missing conventional therapy data since Week 22
  • The YORVIPATH or placebo dose was less than or equal to 30 micrograms per day during the entire study

Nearly 70% of people responded to treatment with YORVIPATH at Week 26

Results from individual measurements in the study§:
Treatment effectiveness chart Treatment effectiveness chart
91.8% of people taking YORVIPATH did not take more than 30 mcg daily at any point during the 26-week study. 
Independence from conventional therapy was defined as no active vitamin D or therapeutic calcium (elemental calcium more than 600 mg per day) with no as-needed doses since Week 22.
The goal of treatment with YORVIPATH is to maintain normal blood calcium levels without the need for active vitamin D or calcium (more than 600 mg per day). Calcium supplementation needed to meet daily dietary requirements may be continued.
§At the end of the study, people who responded to treatment with YORVIPATH had reduced their average daily dose of calcium to 600 mg or less (with none taken as needed) and had eliminated their need for daily active vitamin D. An additional measure of effectiveness was that responders to YORVIPATH did not have any missing active vitamin D or calcium data after Week 22 of the study.
YORVIPATH helped the majority of people in the study to maintain normal blood calcium while reducing—or even eliminating—their need for calcium and active vitamin D

YORVIPATH helped to reduce the amount of calcium and active vitamin D people needed daily

Reduction in the number of daily active vitamin D and calcium pills in the YORVIPATH study

Before the study:
People took an average of 6.7 pills per day
At Week 26:
People on placebo were still taking an average of 5.4 pills per day
People on YORVIPATH were taking an average of 0.5 pills per day
All people in the study were part of this analysis, including those who received YORVIPATH doses of more than 30 mcg/day at any point during the study.

“The biggest difference is that I feel like I’m able to more predictably manage my hypoparathyroidism. There aren’t as many ups and downs, and the lows are much less frequent.”
