What the trials found For clinicians

Primary hyperparathyroidism: what the trials found

Cinacalcet has been shown to significantly reduce plasma parathyroid hormone (PTH) levels during the early assessment period (EAP) 6. Clinical data also indicate that Cinacalcet is associated with significant changes in bone mineral density across multiple sites, including the lumbar spine 2, total hip 2, and femoral neck 2.

Long-term administration of Cinacalcet was evaluated regarding dosage adjustments; studies recorded varying frequencies of dose or frequency changes during the first 3 months, at 3-6 months, and after 6 months post-initiation 11.

Other interventions investigated in primary hyperparathyroidism include Vitamin D3 1, Cholecalciferol 7, eplerenone (which showed no significant change in PTH or calcium levels 3), and KHK7580 5. Additionally, 18F-Fluorocholine was utilized in clinical trials 4.

Recent results — preliminary, needs further review

  • The PTeye imaging technique was evaluated for identifying parathyroid glands; results showed no significant difference in the average number of glands identified (2.7 vs 2.6) or PTH levels 5-14 days post-surgery (23 vs 25.3), but did show a statistically significant difference in the proportion of patients achieving an appropriate intraoperative PTH drop 9.

For the clinician treating this condition

  • Cinacalcet is effective for reducing plasma parathyroid hormone levels and is associated with measurable changes in lumbar spine, total hip, and femoral neck bone mineral density.
  • Eplerenone did not demonstrate a statistically significant effect on PTH or calcium levels in clinical trials.
  • PTeye imaging shows promise in surgical navigation, though it did not significantly change the average number of glands identified compared to standard methods.
