About
This is a multicenter, open label, randomized study investigating two dose titration regimens of CXA-10 in subjects at least 18 years of age with primary FSGS.
The study will be performed at approximately 25 study centers across the United States of America (USA). The recruitment period is anticipated to be up to approximately 16 months. Approximately 30 subjects will be randomized to ensure 26 subjects complete the study. An optional 9 month open label is available
Full description
This is a multicenter, open label, randomized study investigating two dose titration regimens of CXA-10 in subjects at least 18 years of age with primary FSGS.
The study will be performed at approximately 25 study centers across the United States of America (USA). The recruitment period is anticipated to be up to approximately 16 months. Approximately 30 subjects will be randomized.
Study participation for each subject will last up to 5 months. The study will consist of a screening period not to exceed 30 days (1 month), 90-day (3 month) treatment period, and an approximate 28-day (1 month) follow-up period after the last dose of study medication. An optional 9 month open label is available.

Inclusion criteria
Exclusion criteria
The subject has collapsing variant of FSGS on renal biopsy.
The subject has secondary FSGS.
The subject has diabetic nephropathy.
The subject has any other form of acquired (including biopsy proven obesity-induced FSGS) or hereditary glomerular nephropathy.
The subject has a prolonged QTcF interval.
The subject is hypertensive.
The subject has a history of clinically significant cardiovascular events, arrhythmias, recurrent fainting, palpitations, or family history of congenital prolonged QT syndromes or sudden unexpected death due to a cardiac reason.
The subject has any known bleeding disorders or significant active peptic ulceration in the opinion of the investigator that precludes enrollment into this study.
The subject has clinically significant anemia in the opinion of the investigator that precludes enrollment into this study.
The subject has a history of any primary malignancy, including a history of melanoma or suspicious undiagnosed skin lesions, with the exception of the following:
The subject has a history of organ transplantation.
The subject has a history of HIV.
At the time of Screening (Visit 1), the subject has any co-existing disease or condition.
Since the time of presentation of symptoms/diagnosis of FSGS: the subject has received systemic (oral or parenteral) high-dose, long-term corticosteroid therapy (prednisone or alternative glucocorticoid) to treat kidney disease
Subject has a history of immunosuppressant therapy (calcineurin inhibitors, rituximab, or other non-steroid immunosuppressants).
The subject has a history of herbal or natural medication use (including fish oil) within 2 weeks or 5 half-lives, whichever is longer, prior to Baseline
The subject is currently taking a drug that may affect the measurement of serum creatinine (e.g. cimetidine, Bactrim, Pyridium).
The subject is currently taking a newly prescribed drug or new prescription for an increased dose of an existing drug that is known to prolong the QTc interval and has been associated with Torsades de pointes (a list is provided in Appendix H). Note: Stable doses of these drugs are permitted (i.e., subject has received the same dose and regimen for at least 30 days prior to Screening [Visit 1] with no anticipated changes to the dose or regimen during the study).
The subject is currently taking endothelin receptor antagonists, dimethyl fumarate (Tecfidera™), orlistat, fibrates (fenofibrate, bezafibrate, gemfibrozil and ciprofibrate), niacin or lomatapide.
The subject has any of the following abnormal laboratories at Screening:
Female subject with a positive urine beta-human chorionic gonadotropin (β-hCG) test at Screening (Visit 1) (all females) or Baseline (Visit 2) (females of childbearing potential or with a history of bilateral tubal ligation in the absence of documented menopause).
The subject has received a live attenuated vaccine within 6 weeks prior to Baseline (Visit 2) or plans to receive a live attenuated vaccine during the study period.
The subject has a recent history (within one year prior to Screening [Visit 1]) of abusing alcohol or illicit drugs (including marijuana) or history of extensive illicit intravenous drug use.
Any other condition and/or situation that causes the Investigator to deem a subject unsuitable for the study (e.g., due to expected study medication non-compliance, inability to medically tolerate the study procedures, or a subject's unwillingness to comply with study-related procedures).
The subject has known hypersensitivity to CXA-10, its metabolites, or formulation excipients.
The subject has had treatment with any investigational drug or device within 30 days or 5 half-lives (whichever is longer) prior to Screening (Visit 1) (this includes investigational formulations of marketed products, inhaled and topical drugs), or plans to participate in another investigational drug or device study at any time during this study.
