A Phase 1 interventional study of Intravenous fosmanogepix and Intravenous fosmanogepix in End Stage Renal Disease on Dialysis and Adult, sponsored by Basilea Pharmaceutica. Recruiting at 2 sites in United States. Open to participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-11-04.

Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • of 18 to 42 kg/m2, inclusive, and a total body weight > 50 kg at Screening.
  • Subjects with normal renal function only: Estimated (eGFR) ≥ 90 mL/min
  • Subjects with ESRD requiring IHD only: Hemodialysis treatment for at least 3 months prior to Screening, with dialysis performed ≥ 3 times per week and adequate dialysis efficiency as established by document Kt/V ≥ 1.2 on current regimen. The clinical status of the underlying ESRD should be stable

Exclusion criteria

Exclusion Criteria:

  • Subjects who are pregnant, breastfeeding, or plan to become pregnant during the study.
  • Laboratory abnormality or other medical or psychiatric condition, including recent (within the past year) or active suicidal ideation/behavior, that may increase the risk to study participation, or in the Investigator's judgment, make the subject inappropriate for the study.
  • History or presence of clinically-significant disorders, which, in the opinion of the Investigator, are capable of significantly altering the distribution, metabolism, or elimination of the study drug.
  • Renal or liver transplant recipients
  • Hepatic impairment not related to ESRD
  • Use of any prohibited medication within five half-lives plus 14 days prior to Day -1

Subjects with ESRD requiring IHD only:

-Not on stable dosing regimen (i.e., \< 3 weeks prior to Screening) of prescription/ non prescription drugs (including dietary/herbal supplements) for the treatment of a stable concomitant disease

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Primary outcomes

  1. Maximum Plasma Concentration (Cmax) of manogepix

    Cmax of manogepix will be assessed in participants with ESRD in Period 2 and compared with that of healthy participants in Period 1.

    Time frame: Blood sampling in Period 1: At Day 1, 2, 3, 4, 5 and 6. Blood sampling in Period 2: At Day 1, 2, 3, 4, 5, 6, 8, 11, 13 and 15.

  2. Area under the concentration-time curve (AUC) of manogepix
