A Study to Test the Safety of the Study Drug Fosmanogepix and How the Body Handles It in Adults With Severe Kidney Failure on Dialysis

October 29, 2026 updated by: Basilea Pharmaceutica

A Phase 1, Non-randomized, Open-label, Multi-center Study to Assess the Pharmacokinetics, Safety, and Tolerability of Intravenous Fosmanogepix in Adult Subjects With End-stage Renal Disease Requiring Intermittent Hemodialysis

This study will evaluate how fosmanogepix is processed by the body (pharmacokinetics, PK) in participants with kidney failure (end-stage renal disease (ESRD) requiring intermittent hemodialysis (IHD) compared with participants with normal kidney function (control group). Fosmanogepix is given by intravenous infusion and is converted in the body to manogepix, the active form of the drug. Fosmanogepix is an investigational and has not been approved by the United States Food and Drug Administration (FDA) or any other regulatory authority for use in humans.

The study will also evaluate the effect of hemodialysis on manogepix levels in participants with ESRD.

The safety and tolerability of fosmanogepix will also be assessed in participants with kidney failure and in matched participants with normal kidney function.

Participation in the study will last up to 11 weeks and will include up to two study periods. Participants with ESDR requiring IHD will receive fosmanogepix in two study periods. Healthy participants will receive fosmanogepix in one study period.

The study will be conducted at two study sites in the United States.

  • Phase 1

Expanded Access

Expanded Access

A way for patients with serious diseases or conditions who cannot participate in a clinical trial to gain access to a medical product that has not been approved by the U.S. Food and Drug Administration (FDA). Also called compassionate use. There are different expanded access types.
Available

Available

  • Available: Expanded access is currently available for this investigational treatment, and patients who are not participants in the clinical study may be able to gain access to the drug, biologic, or medical device being studied.
  • No longer available: Expanded access was available for this intervention previously but is not currently available and will not be available in the future.
  • Temporarily not available: Expanded access is not currently available for this intervention but is expected to be available in the future.
  • Approved for marketing: The intervention has been approved by the U.S. Food and Drug Administration for use by the public.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (Adult, Older Adult)

Exclusion Criteria:
