What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage Change From Baseline in Urinary Protein to Creatinine Ratio (UPCR) Based on 24-hour Urine Collection at Week 13
UPCR is a ratio between two measured substances in urine: milligram of protein per millimole (mmol) of creatinine, reported in units mg/mmol. A decrease in UPCR may be associated with improved renal and cardiovascular function.
Measured: Baseline, Week 13
Secondary outcomes (11)
Number of Participants With Treatment Emergent Adverse Events (TEAEs)
An adverse event was considered treatment emergent relative to a given treatment if the event occurred for the first time during the investigational treatment period and was not seen prior to the start of treatment (during the lead-in period), or the event was seen prior to the start of treatment but increased in severity during treatment. Adverse events occurring during the lead-in period were considered non-treatment emergent. Events that occurred during the follow-Up period were counted as treatment emergent and attributed to the previous treatment taken.
Measured: From Day 1 of treatment up to 9 weeks after last dose of study treatment (up to Week 33)
Number of Participants With Abnormalities in Laboratory Test Parameters
Hemoglobin (Hg), hematocrit, erythrocytes: <0.8*lower limits of normal (LLN); platelets: <0.5*LLN>1.75*upper limits of normal(ULN); leukocytes (leu), glucose-fasting:<0.6*LLN>1.5*ULN; lymphocytes (lym), lym/leu, neutrophils(neu),neu/leu, protein, albumin, phosphate, free thyroxine, thyroid stimulating hormone: <0.8*LLN>1.2*ULN; basophils (bas), bas/leu, eosinophils (eos), eos/leu, monocytes(mon), mon/leu: >1.2*ULN; bilirubin (total, direct, indirect):>1.5*ULN; aspartate aminotransferase(AT), alanine AT, lactate dehydrogenase, alkaline phosphatase:>3.0*ULN; blood urea nitrogen, creatinine, cholesterol (total,LDL,HDL),triglycerides, Hg A1C: >1.3*ULN; sodium: <0.95*LLN>1.05*ULN; potassium, chloride, calcium, magnesium, bicarbonate: <0.9*LLLN>1.1*ULN; prolactin: >1.1*ULN; creatine kinase: >2.0*ULN; urobilinogen: >=1; Urine-specific gravity: <1.003>1.030, pH: <4.5 >8, glucose,protein,bilirubin,nitrite,leukocyte esterase, ketones: >=1.Categories with at-least 1 non-zero values are reported.

Number of Participants With Abnormalities in Electrocardiogram (ECG)
ECG abnormalities criteria included: 1) QTc interval adjusted according to Bazett formula (QTcB) in millisecond (msec): greater than (>) 450, >480, >500, increase from baseline >30, increase from baseline >60; 2) QTc interval adjusted according to Fridericia formula (QTcF) (msec): >450, >480, >500, increase from baseline >30, increase from baseline >60; 3) Heart rate (bpm): RR decrease >25% and to a VR (interval between QRS wave and T wave on ECG) >100; RR (interval between 2 successive R waves on ECG) increase >25% and to a VR <50; 4) Pulse rate (msec): increase >25% and to a value >200; 5) QT (msec): >450, >480, >500, increase from baseline >30, increase from baseline >60; 6) QRS (msec): increase >25% and to a value >110. Categories (timepoints) with at least 1 participant having ECG abnormality in any of the reporting arms, were reported for this outcome measure.
Measured: Weeks 3, 7, 11, 13, 17, 21, 25, 33
Percentage Change From Baseline in Urinary Protein to Creatinine Ratio (UPCR) at Weeks 2, 5, 9 and 13
UPCR is a ratio between two measured substances in urine: mmol of creatinine, reported in units mg/mmol. A decrease in UPCR may be associated with improved renal and cardiovascular function.
Measured: Baseline, Weeks 2, 5, 9 and 13
Percentage Change From Baseline in Estimated Glomerular Filtration Rate (eGFR ) at Weeks 3, 5, 9 and 13
The eGFR was calculated using 4 variable formula developed by the modification of diet in renal disease (MDRD) study group. The 4 variables needed to estimate glomerular filtration rate (GFR) using this formula were serum creatinine concentration, age, sex (for females, eGFR was multiplied by 0.742) and ethnic origin (for African-Caribbean people only, eGFR was multiplied by 1.212). Thus eGFR in milliliter per minute per 1.73 square meter (mL/min/1.73 m^2) = 175*(sCr/88.4)^-1.154*(Age)^-0.203*(0.742 if female)*(1.212 if African-Caribbean). Baseline eGFR was determined predose at Week 0 (Day 1). For Baseline eGFR, the "Low eGFR" group was defined as baseline eGFR < 45 mL/min/1.73m2, and the "High eGFR" group was defined as baseline eGFR > 45 mL/min/1.73 m2.
Measured: Baseline, Weeks 3, 5, 9 and 13

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing PF-06730512 in people with Focal Segmental Glomerulosclerosis (FSGS), run by Pfizer at 110 sites in 12 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 18 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 110 sites in United States, Canada, Germany, United Kingdom, Japan and 7 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 18 Apr 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage Change From Baseline in Urinary Protein to Creatinine Ratio (UPCR) Based on 24-hour Urine Collection at Week 13 (time frame: Baseline, Week 13). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03448692, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2024.
