• Willing to return to enrolling institution for follow-up (during the Active Monitoring Phase of the study)
• Willingness to provide mandatory tissue specimens for correlative research

You may not qualify if…

• Any of the following because this study involves an investigational agent, the genotoxic, mutagenic, and teratogenic effects of which on the developing fetus and newborn are unknown:
• Pregnant persons
• Nursing persons
• Persons of childbearing potential and persons able to father a child who are unwilling to employ adequate contraception
• Uncontrolled intercurrent illness including, but not limited to:
• ongoing or active infection
• symptomatic congestive heart failure
• unstable angina pectoris
• cardiac arrhythmia
• or psychiatric illness/social situations that would limit compliance with study requirements
• Any of the following cardiac criteria:
• Marked baseline prolongation of QT/QTc interval (e.g., repeated demonstration of a QTc interval >480 milliseconds (ms) (CTCAE Grade 1) using Fredericia's QT correction formula.
• History of additional risk factors for Torsades de Pointes (e.g., heart failure, hypokalemia, family history of Long QT. Syndrome).
• Use of concomitant medications that prolong the QT/QTc interval
• History of myocardial infarction ≤6 months prior to registration, or congestive heart failure requiring use of ongoing maintenance therapy for life-threatening ventricular arrhythmias
• Known coagulopathy increasing the risk of bleeding or history of clinically significant hemorrhage, including significant intracranial tumor related hemorrhage
• Any of the following medications:
• Enzyme-inducing anticonvulsants within two weeks of enrollment NOTE: Patients can be enrolled after a change to non-enzyme inducing anticonvulsants)
• Patients taking more than 8 mg of dexamethasone per day (or equivalent steroid dose) at time of enrollment
• Any of the following prior therapies:
• Radiation therapy <= 26 weeks prior to registration (including gamma tiles)
• Chemotherapy, immunotherapy, or any investigational drug <= four weeks prior to registration,
• or carmustine (BCNU) or lomustine (CCNU) <= six weeks prior to registration
• Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease
• History of hypersensitivity to active or inactive excipients of WSD0628 or drugs with a similar chemical structure or class to WSD0628
