Safety and Efficacy of ONTO1 in Lupus
ONT01 is a drug that is being studied for the treatment of Lupus Nephritis (LN) and Systemic Lupus Erythematosus (SLE) and is not approved by the FDA. The purpose of this study is to better determine whether ONT01 is safe and tolerated by people with lupus nephritis or SLE. The study also looks at how the administration of ONT01 in combination with widely used treatments given for lupus, including the medication mycophenolate mofetil and others, can improve symptoms of lupus. A total of 61 participants will be enrolled in this study.
• ≥ 18 years old and able to provide informed consent to participate.
• Diagnosis of SLE and have fulfilled the ACR classification criteria for SLE during the course of their disease.
• Active non-renal SLE, with one active non-renal clinical manifestation, who have failed at least 1 disease modifying anti-rheumatic drug (DMARD) therapy (not including hydroxychloroquine and corticosteroids)
‣ Active non-renal SLE is defined as having a SLEDAI of 6 or greater (with at least 1 non-renal clinical domain) OR Active nephritis defined as having a no or partial response after initial induction and maintenance therapy with mycophenolate mofetil (and other standard of care therapies) for 3 months or more for class III, IV, IV, V (or combination) nephritis.
⁃ Active LN is defined as follows: a. kidney biopsy showing Class III, IV, V, III+V, or IV+V, within 1 year from screening, AND b. 24-hour urine protein/creatinine ratio \>=1g/g at screening, AND c. absence of partial renal response (PRR)
⁃ Partial renal response (PRR) is defined as a. 24-hour UPCR improved by \>=25% after 3 months from the start of induction standard of care (SOC) therapy (baseline), or \>= 50% after 6 months from the induction therapy (UPCR), AND b. 24-hour UPCR\<2g/g if baseline was \< 3g/g, OR \< 3g/g if baseline at induction was \>= 3g/g. AND d. EGFR\>=60 ml/min/1.73 M2 or no less than 80% of Baseline eGFR (at induction) AND e. No intercurrent rescue therapy, death, or early SOC treatment discontinuation or study withdrawal No response (NR) is defined as a. no achievement of at least a partial renal response, OR b. use of intercurrent rescue therapy, OR c. death
• Female patients who are women of childbearing potential must agree to use a highly effective form of contraception during the study and for at least 120 days after last exposure to study drug. Male patients with female partners of childbearing potential must use effective barrier contraception (i.e., condoms) during the study and for at least 120 days after last exposure to study drug. Also, patients may not proceed with sperm or egg donation during the study and for at least 120 days after the last exposure to study drug
