Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This multicenter, randomized, double-blind, placebo-controlled clinical trial will evaluate the efficacy and safety of intravenous Sodium Thiosulfate Injection for treatment of acute calciphylaxis-associated pain in chronic hemodialysis patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

This Phase 3, multicenter, randomized, double-blind, placebo-controlled clinical trial will evaluate the efficacy and safety of intravenous Sodium Thiosulfate Injection for treatment of acute calciphylaxis-associated pain in chronic hemodialysis patients. Acute calciphylaxis- associated pain intensity will be the primary outcome measure.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Informed of the investigational nature of the study and sign written informed consent
* Willing and able to adhere to all study-related procedures, including adherence to study medication regimen
* Male or female ≥18 years old
* End-stage renal disease on chronic hemodialysis
* Calciphylaxis with active skin lesion(s) of any morphological appearance (including but not limited to livedo, induration, ulceration, etc.) and tissue histology review consistent with calciphylaxis diagnosis. Histological features consistent with calciphylaxis will include soft tissue calcification, microthrombosis, and/or fibrointimal hyperplasia of dermal arterioles
* Acute pain associated with calciphylaxis lesions pain intensity score of ≥ 5 at initial screening on the modified BPI/SF scale
* Women of childbearing potential must have a pregnancy test (urine or serum \[if anuric\]) at screening and not be pregnant and willing to use an acceptable method of contraception for the entire duration of the study (3 weeks)

Exclusion Criteria

* Peritoneal dialysis patients
* Current congestive heart failure exacerbation
* Baseline abnormalities related to QT prolongation (corrected QT interval \> 470 ms), hypocalcemia (serum albumin-corrected calcium \< 8 mg/dL ), metabolic acidosis (serum bicarbonate \< 18 mmol/L, hypotension (resting systolic blood pressure while seated \< 80), or interdialytic weight gain ≥ 4.0 kg
* History of ventricular arrhythmias including ventricular fibrillation or ventricular tachycardia associated with shortness of breath, dizziness, hypotension, or syncope
* Any prior (within the past 30 days) or current intravenous Sodium Thiosulfate Injection treatment
* Other investigational agent (drug, biologic, or device) study within the past 30 days and/or for the duration of the trial
* Pregnant or lactating women
* History of allergy to sulfites, thiosulfate, or any component in Sodium Thiosulfate Injection (sulfa allergy is not an exclusion criterion)
* Significant other acute or chronic concomitant diseases (including but not limited to hepatic, cardiovascular, pulmonary, or oncologic disease, sepsis, pulmonary edema, pulmonary embolism) that would be inconsistent with survival for at least 3 months
* Other serious concurrent or recent medical or psychiatric condition which, in the opinion of the Investigator, makes the patient unsuitable for participation in this study
* Ongoing application of dialysate admixed with iron salt e.g. ferric pyrophosphate during the entire trial period (patients who are on dialysate admixed with iron salt at screening are eligible if dialysate admixed with iron salt can be substituted with non-iron based dialysate and patients can be maintained on non-iron based dialysate therapy for the entire duration of trial period)
* Recent (within 1 week) history of surgical parathyroidectomy or scheduled for surgical parathyroidectomy during the course of the study
* History of opioid addiction
