Study of Safety and Efficacy of LNP023 in Patients With Kidney Disease Caused by Inflammation

An Adaptive Seamless Randomized, Double-blind, Placebo-controlled, Dose Ranging Study to Investigate the Efficacy and Safety of LNP023 in Primary IgA Nephropathy Patients

Efficacy and safety of LNP023 in IgAN patients

Study Overview

• Status: Completed
• Conditions: IgA Nephropathy
• Intervention / Treatment: Other: Placebo; Drug: LNP023

Detailed Description

This was a multicenter, randomized, double-blind, dose-ranging, parallel-group study with an adaptive design (Part 1 informed the design adaptations for Part 2). In Part 1, three doses of LNP023 (10 mg, 50 mg, and 200 mg) vs. placebo control were compared; In Part 2, four doses of LNP023 (10 mg, 50 mg, 100 mg, and 200 mg) vs. placebo control were compared. The study comprised a run-in phase in order that patients were on stable and maximally tolerated dose of Angiotensin-converting-enzyme inhibitor (ACEi) or Angiotensin II Receptor Blockers (ARB) for at least 90 days, a 90 days treatment phase in Part 1; a 180 days treatment phase in Part 2 and a 90 days follow-up phase in both Parts 1 and 2.

2. Patients previously treated with immunosuppressive agents such as cyclophosphamide or mycophenolate mofetil (MMF), or cyclosporine, systemic corticosteroids exposure within 90 days prior to start of LNP023/Placebo dosing
3. Use of other investigational drugs at the time of enrollment, or within 5 half-lives of enrollment, or within 30 days, whichever is longer; or longer if required by local regulations
4. All transplanted patients (any organ, including bone marrow)

5. History of immunodeficiency diseases, or a positive HIV (ELISA and Western blot) test result.

   Chronic infection with Hepatitis B (HBV) or Hepatitis C (HCV). A positive HBV surface antigen (HBsAg) test, or if standard local practice, a positive HBV core antigen test, excludes a patient. Patients with a positive HCV antibody test should have HCV RNA levels measured. Subjects with positive (detectable) HCV RNA should be excluded

6. Any surgical or medical condition which might significantly alter the absorption, distribution, metabolism, or excretion of drugs, or which may jeopardize the subject in case of participation in the study. The Investigator should make this determination in consideration of the subject's medical history and/or clinical or laboratory evidence of any of the following:

   • A history of invasive infections caused by encapsulated organisms, e.g. meningococcus or pneumococcus
   • Splenectomy
   • Inflammatory bowel disease, peptic ulcers, severe gastrointestinal disorder including rectal bleeding;
   • Major gastrointestinal tract surgery such as gastrectomy, gastroenterostomy, or bowel resection;

   • Any single parameter of ALT, AST, GGT, alkaline phosphatase or serum bilirubin must not exceed 3 x upper limit of normal (ULN)
   • PT/INR must be within the reference range of normal individuals
   • Evidence of urinary obstruction or difficulty in voiding any urinary tract disorder other than IgNA that is associated with hematuria at screening and before dosing; [If necessary, laboratory testing may be repeated on one occasion (as soon as possible) prior to randomization, to rule out any laboratory error]
7. Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test.

8. A history of clinically significant ECG abnormalities, or any of the following ECG abnormalities at screening or baseline:

11. Donation or loss of 400 mL or more of blood within eight (8) weeks prior to initial dosing, or longer if required by local regulation

12. Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception during dosing and for 1 week after stopping of investigational drug. Highly effective contraception methods include:

    • Total abstinence from heterosexual intercourse (when this is in line with the preferred and usual lifestyle of the subject). Periodic abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception.
    • Female sterilization (have had surgical bilateral oophorectomy with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks before taking investigational drug. In case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment.
    • Male sterilization (at least 6 months prior to screening). For female subjects on the study the vasectomized male partner should be the sole partner for that subject.
    • Use of oral (estrogen and progesterone), injected or implanted hormonal methods of contraception or placement of an intrauterine device (IUD) or intrauterine system (IUS) or other forms of hormonal contraception that have comparable efficacy (failure <1%), for example hormone vaginal ring or transdermal hormone contraception In case of use of oral contraception women should have been stable on the same pill for a minimum of 3 months before taking investigational drug.

    If local regulations deviate from the contraception methods listed above and require more extensive measures to prevent pregnancy, local regulations apply and will be described in the ICF.

    Women are considered post-menopausal and not of child bearing potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy), total hysterectomy or tubal ligation at least six weeks ago. In the case of oophorectomy alone, only when the reproductive status of the woman has been confirmed by follow up hormone level assessment is she considered not of child bearing potential.

13. History of malignancy of any organ system (other than localized basal cell carcinoma of the skin or in-situ cervical cancer), treated or untreated, within the past 5 years, regardless of whether there is evidence of local recurrence or metastases
14. History of any porphyria metabolic disorder
15. History of drug or alcohol abuse within the 12 months prior to dosing, or evidence of such abuse as indicated by the laboratory assays conducted during screening and baseline.
16. History of hypersensitivity to any of the study treatments or excipients or to drugs of similar chemical classes

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
MCP-Mod Estimates of the Ratio to Baseline of Urine Protein to Creatinine Ratio (UPCR) (g/Mol) - Parts 1 and 2 at Day 90	The primary analysis of the dose-response effect of LNP023 versus placebo on the reduction in UPCR 24 hours at Day 90 was done using Multiple Comparison Procedure Modelling (MCP-Mod). The existence of a dose-response relationship was assessed at the MCP step at the one-sided 10% significance level vis a multiple contrasts test. In the Mod step, the mean predicted difference between each LNP023 dose and placebo were then estimated using parametric bootstrap model averaging. Results are presented on the original scale as geometric mean ratios. A ratio less than 1 indicates a reduction in proteinuria. Participants collected all urine over a 24 hour period for UPCR test.
