Study summary

This is a Phase 2, randomized, double-blind, placebo-controlled, multicenter study designed to evaluate the efficacy and safety of praliciguat in adults with biopsy-confirmed focal segmental glomerulosclerosis (FSGS). Participants will be randomized 1:1 to receive praliciguat or placebo for initial 24 week treatment period. Following this double-blind period, all participants will receive praliciguat in an open-label period for an additional 24 weeks. Participants responding to treatment will be offered the opportunity to participate in the long-term safety extension study.

Eligibility criteria

Inclusion Criteria (Part A):

  1. UPCR ≥1 (g/g) during screening.
  2. On maximally tolerated ACEi or ARB per principal investigator discretion within 1 month of .
  3. Estimated ≥25 milliliters per minute per 1.73 square meters by Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation.
  4. Kidney collected within 5 years of screening consistent with FSGS or kidney biopsy collected ≥5 years prior to screening consistent with FSGS plus the presence of a pathogenic gene mutation known to be associated with FSGS.

Exclusion Criteria (Part A):

  1. Collapsing FSGS in the kidney biopsy report.
  2. Sickle cell disease.
  3. >8%.
  4. Uncontrolled hypertension (≥160/100 millimeters of mercury).

Inclusion Criteria (Part B):

1. Participants responding to treatment will be offered the opportunity to participate in the long-term safety extension study.

Terms in these criteria, in plain language(4)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

2 registry updates since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Dec 2025 (actual). Primary completion is estimated for Jun 2027, 18 months after the start.

Of 17 phase 2 interventional studies under Glomerulosclerosis, Focal Segmental, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 21 and three quarters within 42. This study's planned 18 months is below that.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
