Summary: Lynch syndrome (LS) is the most common genetic predisposition syndrome for colorectal cancer (CRC), responsible for around 2-4% of cancers. It is characterized by a pathogenic germline mutation in one of the DNA mismatch repair genes (path\_MMR) MLH1, MSH2, MSH6, PMS2 or a deletion in the 3' region of the Epcam gene. Patients followed up for LS are at high risk of developing CRC at an early age, a...

Summary: The objective of this study is to evaluate real world long-term functional outcomes, safety and performance of the Indigo Aspiration System for the treatment of pulmonary embolism (PE).

Summary: The objective of this study is to demonstrate the safety and efficacy of the Indigo Aspiration system for percutaneous mechanical thrombectomy in a population presenting with obstruction due to deep vein thrombosis (DVT) who are eligible for treatment.

Summary: The primary objective of this study is to collect and evaluate clinical evidence supporting the safety and performance of the Indigo™ Aspiration System in a patient population with lower extremity acute limb ischemia (LE ALI).

Summary: The objective of The Neighborhood \& Health Study is to use a quasi-experimental mixed-methods approach to assess the impact of living in an agrihood-an agriculturally integrated community. This study follows a longitudinal cohort of residents of a newly developed neighborhood (the Indigo Neighborhood) and a geographically and socio-demographically matched neighborhood (the Elyson Neighborhood), b...

Summary: Detection and removal of polyps during colonoscopy is crucial for the prevention of colorectal cancer. Indigo carmine spraying up to the colonic mucosa could probably increase the adenoma detection rate, but considering the long withdrawal time of the endoscope and the resulting increase in time and cost. Linked-color imaging (LCI) is a newly developed image-enhanced endoscopy technology. It relie...

Summary: This is an open label, randomized, multicenter study to evaluate the efficacy and safety of two dose levels (2.5 mL and 5.0 mL) of Indigotindisulfonate Sodium Injection, USP 0.8% when used as an aid in the determination of ureteral patency in patients with different degrees of renal impairment.

Summary: To evaluate the feasibility, applicability, effectiveness, and health-economic value of the risk-based sequential screening modality for esophageal and gastric cancers, the investigators aim to initiate a community-based randomized controlled trial in Xun County, Henan Province, which is a high-risk region of upper gastrointestinal cancer (UGIC) in northern China. A total of 258 target villages fr...

Summary: This is a randomized, multicenter study to evaluate the efficacy and safety of two dose levels (2.5 mL and 5.0 mL) of Bludigo™ (indigotindisulfonate Sodium Injection, USP) 0.8% when used as an aid in the determination of ureteral patency. Subjects scheduled for a surgical procedure in which the patency of the ureter must be assessed by cystoscopy following the procedure, age 18 to 85 years inclusi...

Summary: In recent years, the prognosis of pediatric relapsed ALL patients has improved, but the 5-year OS of patients with first recurrence is still less than 50%. A number of in vitro studies have shown that arsenic trioxide (ATO) can selectively inhibit the growth and induce apoptosis in a variety of leukemia cell lines, suggesting that ATO as a synergist combined with other common chemotherapy drugs ma...
