  • 3. Secondary etiologies of IgAN (eg, inflammatory bowel disease, celiac disease)
  • 4. Diagnosis of Henoch-Schonlein Purpura (IgA Vasculitis)
  • 5. eGFR <30 mL/min/1.73 m2 2 weeks prior to randomization (local results may be used for assessment of eligibility)
  • 6. Has any of the following laboratory parameter assessments:
  • a. Alanine transaminase (ALT) >1.5×upper limit of normal (ULN), International Normalized Ratio (INR) >2 (or >3.5 if on anticoagulants), or total bilirubin >1.5×ULN (unless bilirubin elevation is due to Gilbert’s syndrome)
  • 7. Confirmed positive IgG/IgM/IgA ADAs to cemdisiran at Screening
  • 8. Clinical laboratory test results considered clinically relevant and unacceptable in the opinion of the Investigator
  • 9. Positive hepatitis B virus (HBV) surface antigen, HBV core antibody, hepatitis C virus (HCV) antibody (unless HCV viral load demonstrated negative)
  • 10. Treatment with systemic steroids for more than 7 days or other immunosuppressant agents in the 6 months prior to randomization
  • 11.Treatment with dual RAS blockade in the 3 months prior to entry into the run-in phase
  • 12. Received an investigational agent within the last 30 days or 5 half-lives, whichever is longer, prior to the first dose of study drug, or are in follow-up of another clinical study prior to study enrollment

  • 18. History of multiple drug allergies or history of allergic reaction to an oligonucleotide or GalNAc
  • 19. History of intolerance to SC injection(s) or significant abdominal scarring that could potentially hinder study drug administration or evaluation of local tolerability
  • 20. Known contraindication to meningococcal vaccines (group ACWY conjugate and group B vaccines) required for this study. Refer to the most recent local product information for each vaccine for the current list of contraindications
  • 21. Unable to take antibiotics for meninigococcal prophylaxis, if required by local standard of care
  • 22. Sustained blood pressure >140/90 mmHg as defined by 2 or more readings during the run-in period, measured in supine position after 10 minutes of rest

This is a clinical trial to evaluate efficacy and safety of a drug activating the immune system MGN1703 in patients with advanced colorectal cancer, which achieved disease stabilization or improvement after initial chemotherapy. The patients will be assigned occasionally (like by tossing a coin) either to treatment with MGN1703 or with placebo, a preparation matching MGN1703, however, without the active substance.Patients with advanced colorectal carcinoma (AJCC Stage IV) with disease control after initial first-line therapyMedDRA version: 14.1Level: LLTClassification code 10010036Term: Colorectal carcinomaSystem Organ Class: 100000004864
