Frequently asked questions about CTAP101 30 μg

What is CTAP101 30 μg used for?

CTAP101 30 μg is an investigational small molecule being developed for chronic kidney disease (CKD), specifically to treat secondary hyperparathyroidism in patients with stage 3 or 4 CKD and vitamin D insufficiency. It is currently in Phase 3 clinical development and has not been approved by the FDA.

What does CTAP101 30 μg target?

CTAP101 30 μg is a small molecule being studied for its effects on secondary hyperparathyroidism in chronic kidney disease. The specific molecular target is not disclosed in the available information, but the drug is intended to address vitamin D insufficiency and related parathyroid hormone dysregulation in CKD patients.

Who makes CTAP101 30 μg?

CTAP101 30 μg is being developed by Opko Health Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol OPK. The company is conducting Phase 3 clinical trials to evaluate the drug's safety and efficacy in patients with chronic kidney disease and secondary hyperparathyroidism.

What phase is CTAP101 30 μg in?

CTAP101 30 μg is in Phase 3 clinical development. Two Phase 3 trials have been completed, both evaluating the drug's safety and efficacy in treating secondary hyperparathyroidism in stage 3 or 4 chronic kidney disease with vitamin D insufficiency. The drug remains investigational and is not yet FDA approved.

What clinical trials is CTAP101 30 μg in?

CTAP101 30 μg has been studied in two completed Phase 3 clinical trials: NCT01651000 and NCT01704079. Both trials enrolled a total of 429 patients with chronic kidney disease, secondary hyperparathyroidism, and vitamin D deficiency. The trials were randomized, double-blind, placebo-controlled, and conducted in the United States.

Is CTAP101 30 μg the same as CTAP101?

CTAP101 30 μg is a specific dose formulation of CTAP101, a drug candidate being developed by Opko Health Inc. for secondary hyperparathyroidism in chronic kidney disease. The 30 μg designation refers to the dose strength studied in clinical trials, while CTAP101 refers to the drug substance itself.
