Osteoporosis, bone & mineral

An Open-label Phase 2 Study of Eneboparatide, a Novel PTH Receptor 1 Agonist, in Hypoparathyroidism

J Clin Endocrinol MetabPublished Phase 2 open-label study

Authors' conclusion

Eneboparatide allowed independence from conventional therapy and maintenance of serum calcium within a target range while normalizing uCa excretion and producing a balanced resumption of bone turnover.

Study context

Population
Patients with chronic hypoparathyroidism (HP); 21 women, 7 men; mean age 58 years (range 28–72)
Participants
28 patients
Comparison
Eneboparatide starting dose 20 µg/day vs 10 µg/day
  • C1n = 12
  • C2n = 16
Outcome
Proportion of patients achieving independence from conventional therapy
Follow-up
3 months
Methodological details2 consecutive cohorts
  • 2 consecutive cohorts

Main finding

As reported in the abstract

Independence from conventional therapy

Patients achieving independence from conventional therapy

≥ 88%

Further findings

24-h urine calcium

Rapid and sustained reduction of mean 24-h urine calcium (uCa), even in patients with hypercalciuria

Bone turnover markers and bone mineral density (BMD)

Bone turnover markers slightly increased; BMD unchanged

Safety

Eneboparatide was well tolerated with no serious adverse events (AEs)
