ECG abnormalities:

Prolonged QTcF (Fredericia's correction) interval on screening ECG (≥ 450 msec)
QRS ˃ 120 msec
PR ˃ 210 msec
Any prior history, or current evidence of second- or third-degree heart block
Heart rate ˂ 40 beats per minute at screening
ECG second degree heart block (Mobitz's Type 2 or Wenckebach)
Complete heart block
Left bundle branch block or bifascicular block (right bundle branch block and left anterior hemiblock together)
Episodes of ventricular tachycardia
Any known prior malignancy (not including non-melanoma skin cancers), unless treated with curative intent
A serious uncontrolled medical disorder or active infection, which would impair the ability of the subject to receive protocol therapy
Current or recent (within 3 months) gastrointestinal disease that could impact the absorption (i.e., unmanageable diarrhea or malabsorption at the time of screening)

Inadequate bone marrow function defined as:

Absolute neutrophil count (ANC) ˂ 1,500 cells/mm3
Platelet count ˂ 100,000 cells/mm3
Hemoglobin ˂ 9 g/dL

Inadequate hepatic function defined as:

Total bilirubin ˃ 1.5 x institutional upper limit of normal (IULN) (Unless due to diagnosis of Gilbert's Syndrome)
Alanine aminotransaminase (ALT) and aspartate aminotransaminase (AST) ˃ 2.5 x IULN

Patients with known symptomatic brain metastasis. Subjects with controlled brain metastasis (no radiographic progression at least 4 weeks following radiation and/or surgical treatment and no neurological signs or symptoms) will be allowed
History of allergy to merestinib or chemically related compounds
History of osteonecrosis of the jaw
Change in chemotherapy or hormone therapy within 8 weeks of the start of the study.
