Most adverse reactions were manageable with dose modifications and/or standard supportive care. The most common non-hematologic adverse reactions were fatigue (59%), nausea (50%), decreased appetite (35%), and diarrhea (32%) and were mostly Grade 1 and 2 events. The most common Grade 3 and 4 adverse reactions were thrombocytopenia (43%), lymphopenia (38%), fatigue (28%) and anemia (17%).The most common adverse reactions (incidence ≥20%) in people with diffuse large B-cell lymphoma (DLBCL), excluding laboratory abnormalities, were fatigue, nausea, diarrhea, appetite decrease, weight decrease, constipation, vomiting, and pyrexia. Grade 3-4 laboratory abnormalities in ≥15% were thrombocytopenia, lymphopenia, neutropenia, anemia, and hyponatremia. Serious adverse reactions occurred in 46% of people, most often from infection. Thrombocytopenia was the leading cause of dose modifications. Gastrointestinal toxicity developed in 80% of people and any grade hyponatremia developed in 61%. Central neurological adverse reactions occurred in 25% of people, including dizziness and mental status changes.The prescribing information provides warnings and precautions for thrombocytopenia, neutropenia, gastrointestinal toxicity, hyponatremia, serious infection, neurological toxicity, and embryo-fetal toxicity. Mechanism of action
Like other selective inhibitors of nuclear export (SINEs), selinexor works by binding to exportin 1 (also known as XPO1 or  CRM1). XPO1 is a karyopherin which performs nuclear transport of several proteins, including tumor suppressors, oncogenes, and proteins involved in governing cell growth,  from the cell nucleus to the cytoplasm; it is often overexpressed and its function misregulated in several types of cancer.
Edaravone, sold under the brand name Radicava among others, is a medication used to treat stroke and amyotrophic lateral sclerosis (ALS). It is given by intravenous infusion and by mouth.The most common side effects include bruising (contusions), problems walking (gait disturbances), and headaches.The mechanism by which edaravone might be effective is unknown. The medication is known to be an antioxidant, and oxidative stress has been hypothesized to be part of the process that kills neurons in people with ALS.The U.S. Food and Drug Administration (FDA) considers it to be a first-in-class medication. Medical uses
Edaravone is used to help people recover from stroke in Japan, and is used to treat ALS in the US and Japan. Adverse effects
The label carries a warning about the potential for hypersensitivity reactions to edaravone, and adverse effects include bruising, gait disturbances, headache, skin inflammation, eczema, problems breathing, excess sugar in urine, and fungal skin infections.The following adverse effects in at least 2% more people given the medication than were given placebo: bruising, gait disturbances, headache, skin inflammation, eczema, problems breathing, excess sugar in urine, and fungal skin infections.There is no data on whether it is safe for pregnant women to take, and it is unknown if edaravone is secreted in breast milk. Pharmacology
The mechanism by which edaravone might be effective in ALS is unknown.
