The SEAPORT 1 Study: An Open-label Exploratory Study to Evaluate the Safety, Pharmacokinetics, and Pharmacodynamics of INZ-701 in Study Participants With End-Stage Kidney Disease Undergoing Hemodialysis

INZ701-401

The purpose of this study is to determine if multiple doses of INZ-701, given once per week over 4 weeks are safe and increase pyrophosphate (PPi) levels in hemodialysis-dependent (HD) end stage kidney disease (ESKD) study participants who have low PPi levels. In addition, the effect of hemodialysis on the pharmacokinetics of INZ-701 and PPi levels will be evaluated.

Have ESKD and are receiving HD treatment 3. Are compliant with receiving 3 treatments of HD per week with a functioning arteriovenous (AV) fistula, AV graft, or central venous catheter 4. PPi level \<700 nmol/L at Screening 5. Must be willing and able to comply with the diet prescribed by their treating physician and/or the Investigator 6.

WOCBP and partners of fertile males who are WOCBP must be using or agree to use one highly effective form of contraception (per CTFG 2020) and a barrier method from at least 1 month before the first dose of INZ-701 to 30 days after the last dose (greater than 5 half-lives of INZ-701). WOCBP and partners of fertile males who are WOCBP must also agree to not donate ova from the time of the first INZ-701 dose to 30 days after the last dose. 9. Males who are sexually active must agree to use condoms from the time of the first INZ-701 dose to 30 days after the last dose. Males must also agree to not donate sperm from the time of the first INZ-701 dose to 30 days after the last dose. 10. In the opinion of the Investigator, study participants are able and willing to complete all study procedures per protocol. Exclusion Criteria: Individuals meeting any of the following exclusion criteria may not participate: 1. Study participants receiving other types of dialysis than HD (eg, peritoneal dialysis, hemodiafiltration) 2. Study participants who are hospitalized 3. In the opinion of the Investigator, presence of any clinically significant disease or laboratory abnormality that may impact study participation and/or confound interpretation of the study results 4. Malignancy within the last year, except non-melanoma skin cancers or cervical carcinoma in situ 5. Advanced liver disease manifesting as liver cirrhosis 6. Myocardial infarction, stroke, or congestive heart failure requiring hospitalization within the last 6 months 7. Known intolerance to INZ-701 or any of its excipients 8. Weight \>125 kg 9. Concurrent participation in another interventional clinical study and/or receipt of any other investigational new drug within 5 half-lives of the last dose of the other investigational product or from 4 weeks prior to the first dose of INZ-701, whichever is longer, or use of an investigational device, through completion of participation in the study
