NCT05432232
The purpose of this trial is to evaluate the technical success and safety profile of the HistoSonics Investigational System for the treatment of primary solid renal tumors.
NCT07224763
The purpose of this study is to evaluate the safety and efficacy of the GGTA1 KO Thymokidney in patients with end-stage renal disease (ESRD) who are either not eligible for conventional allogeneic kidney transplantation (Group 1) or are on an Organ Procurement and Transplantation Network (OPTN) kidney transplant waitlist, but are more likely to die or go untransplanted within 5 years than receive a kidney transplant (Group 2). The study consists of xenotransplantation followed by a 24-week Post-transplant Follow-up Period (Part A) to evaluate the efficacy and safety objectives followed by a Long-term Follow-up Period (Part B) to evaluate participant survival, GGTA1 KO Thymokidney survival, and screening for zoonotic infections. Part B will continue for the lifetime of the participant or for 52 weeks following nephrectomy, if required.
NCT06100367
* 10% of patients with hypertension potentially have the treatable condition - primary aldosteronism (PA). This is caused by either bilateral adrenal disease (\~40%), managed with lifelong medications; or unilateral disease (\~60%), cured with laparoscopic surgery (adrenalectomy). Current diagnosis of PA includes a screening test with aldosterone-renin ratio, followed by a confirmatory salt loading test (in most patients) to demonstrate unsuppressed aldosterone levels. Of note, some patients with suppressed aldosterone after confirmatory tests (also termed low-renin hypertension) may also have unilateral adrenal tumors. * The difficulty with identifying curable unilateral disease is due to adrenal vein sampling (AVS): an invasive, and technically-difficult procedure. An alternative novel imaging, 11C-Metomidate Positron emission tomography-computed tomography (PET-CT), can detect adrenal tumors which are over-producing aldosterone. It is non-invasive, non-operator-dependent, and potentially may identify more patients with curable unilateral disease. The results from our pilot study in 25 patients with confirmed PA (ClinicalTrials.gov NCT03990701, PA\_CURE) showed that 11C-Metomidate PET-CT exhibited comparable performance to AVS in subtyping PA, and this should be validated in a larger study. * In addition, 11C-Metomidate is also able to differentiate adrenocortical lesions in the adrenal gland from other lesions found in adrenal tissue, such as adrenomedullary lesions (e.g. pheochromocytoma). * Hence, the investigators hypothesize that 11C-metomidate PET-CT can accurately (1) identify patients with surgically curable unilateral adrenal disease among hypertensive Asians with primary aldosteronism (PA\_CURE 2 / PA\_MTO EH study) and (2) differentiate adrenocortical lesions from other lesions in patients with adrenal tumors (PA\_MTO AT study)
