    • Inability to determine the QT interval on screening (QTcF, using Fridericia's correction).
• Systolic blood pressure > 160 mmHg or < 90 mmHg.
• Any other concurrent severe and/or uncontrolled medical condition that would, in the investigator's judgment, cause unacceptable safety risks, contraindicate patient participation in the clinical study or compromise compliance with the protocol (e.g., chronic pancreatitis, chronic active hepatitis, active untreated or uncontrolled fungal, bacterial or viral infections etc.).
• Currently receiving any of the following medications and cannot be discontinued 7 days prior to starting the study:

• Currently receiving or has received systemic corticosteroids (≤ 14 days prior to registration, or who have not fully recovered from side effects of such treatment).
  • NOTE: The following uses of corticosteroids are permitted: single doses, topical applications (e.g., for rash), inhaled sprays (e.g., for obstructive airways diseases), eye drops or local injections (e.g., intra-articular).
• History of non-compliance to medical regimen or inability to grant consent.

  • Note: Therapy with heparin, direct oral anticoagulants, low molecular weight heparin (LMWH) or fondaparinux is allowed.
• Participation in a prior investigational study ≤ 30 days prior to enrollment or within 5 half-lives of the investigational product, whichever is longer.

• Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using highly effective methods of contraception throughout the study and for 8 weeks after study drug discontinuation; highly effective contraception methods include:
  • Total abstinence when this is in line with the preferred and usual lifestyle of the patient; 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 6 weeks before taking study treatment; 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), the vasectomized male partner should be the sole partner for that patient;
  • Use of oral, 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 rate < 1%), for example hormone vaginal ring or transdermal hormone contraception.
    • Note: In case of use of oral contraception, women should have been stable on the same pill for a minimum of 3 months before taking study treatment.
    • Note: Oral contraceptives are allowed but should be used in conjunction with a barrier method of contraception due to unknown effect of drug-drug interaction.
    • Note: 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) is she considered not of child bearing potential.
• Sexually active males unless they use a condom during intercourse while taking the drug and for 21 days after stopping treatment and should not father a child in this period.
  • Note: A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
• Known standard therapy for the patient's disease that is potentially curative or definitely capable of extending life expectancy.
