• - Systemic treatment with strong inhibitors of CYP1A2 (fluvoxamine, enoxacin), strong inhibitors of CYP3A (clarithromycin, telithromycin, itraconazole, voriconazole, ketoconazole, nefazodone, posaconazole) or strong CYP3A inducers (rifampin, rifapentine, rifabutin, carbamazepine, phenytoin, phenobarbital), or use of Ginkgo biloba or St. John's wort within 14 days before the first dose of study treatment.
• - Known intolerance to steroid therapy.

Más betegség

• - Uncontrolled hypertension.
• - Subjects with known chronic obstructive pulmonary disease (COPD) with a Forced Expiratory Volume in 1 second (FEV1) < 50% of predicted normal. Note that FEV1 testing is required for patients suspected of having COPD and subjects must be excluded if FEV1 < 50% of predicted normal.
• - Subjects with a history of moderate or severe persistent asthma within the past 2 years, or with uncontrolled asthma of any classification at the time of screening (Note that subjects who currently have controlled intermittent asthma or controlled mild persistent asthma are allowed in the study).
• - History of allergy to any of the study medications, their analogues, or excipients in the various formulations.
• - Clinically relevant active infection or serious co-morbid medical conditions.
• - Prior malignancy except adequately treated basal cell or squamous cell skin cancer, in situ cervical, breast or prostate cancer free of disease since 5 years.
• - Serious medical or psychiatric illness likely to interfere with participation in study.
• - Uncontrolled diabetes mellitus.
• - Incidence of gastrointestinal disease that may significantly alter the absorption of oral drugs.

Laborértékek

• - Subject has plasma cell leukemia (according to WHO criterion: ≥ 20% of cells in the peripheral blood with an absolute plasma cell count of more than 2 × 109/L) or POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal protein, and skin changes).
• - Active HBV, HCV, SARS-CoV-2, HIV, or any active, uncontrolled bacterial, fungal, or viral infection. Active infections must be resolved at least 21 days prior to enrollment. Treatment with systemic anti-infective agents must have completed at least 28 days prior to enrollment. Prophylactic use of systemic agents is permitted.
  • COVID-19/SARS-CoV-2: SARS-CoV-2 PCR testing is mandated within 5 days prior to enrollment. Participants with positive PCR test result for SARS-CoV-2 within 5 days prior to enrollment, or suspected of having SARS-CoV-2, are excluded.
  • HIV: In equivocal cases, participants whose viral load is negative may be eligible. HIV seropositive participants who are otherwise healthy and at low risk for AIDS-related outcomes could be considered eligible. Potential eligibility for a specific HIV positive protocol candidate should be evaluated and discussed with the sponsor prior to screening, considering current and past CD4+ and T-cell counts, history (if any) of AIDS defining conditions (eg, opportunistic infections), status of HIV treatment and the potential for drug-drug interactions.
  • HBV:
  • Participants with a positive HBsAg test (ie, either acute or chronic active hepatitis) are excluded.
  • Participants with HBV antibody positivity indicating immunity, either due to vaccination or prior natural infection, are eligible.
  • Participants with positive anti-HBcAb but negative HBsAg and negative anti-HBsAb profile are eligible if HBV DNA is not detected.
  • For additional details, refer to CDC website (https://www.cdc.gov/hepatitis/HBV/PDFs/SerologicChartv8.pdf).
  • HCV: Positive HCV antibody is indicative of infection but may not necessarily render a potential candidate ineligible, depending on clinical circumstances. If exposure to HCV is recent, HCV antibody may not have yet turned positive. In these circumstances it is recommended to test for HCV RNA. If HCV RNA is detected, the patient is not eligible. Refer to CDC website for further details(https://www.cdc.gov/hepatitis/hcv/pdfs/hcv_graph.pdf).
