- Clinical signs of pulmonary hemorrhage and/or hemoptysis during examination and in the anamnesis.
- Confirmed eye injuries with vitreous hemorrhage during the last 6 months according to the medical history.
- Malignant neoplasms of any localization in the anamnesis, with the exception of in situ carcinoma, which required only surgical treatment.
- Renal failure.
- Taking drugs of prohibited therapy since the start of screening in this study.
- Serological test positive for HIV infection, viral hepatitis B and C.
- Pregnancy or breastfeeding.
- Participation in clinical trials of an experimental drug within 30 days prior to screening for participation in the current study.
