Abstract Text

Inhibition of transforming growth factor-beta receptor I (TGF-beta RI)-mediated signaling pathways blocks tumor growth and metastases in nonclinical studies. Galunisertib (LY2157299), a small molecule inhibitor of TGF-beta RI serine/threonine kinase, had antitumor effects with acceptable safety/tolerability in a first-in-human dose (FHD) study conducted mainly in Caucasian patients with glioma. In this nonrandomized, open-label, dose-escalation study, we assessed safety/tolerability, pharmacokinetics (PK), and tumor response in Japanese patients.Patients with advanced and/or metastatic disease refractory were assigned sequentially to Cohort-1 (80 mg) or Cohort-2 (150 mg) of galunisertib, administered twice daily and treated using 2-week on, 2-week off treatment cycles. Dose escalation was guided by predefined PK criteria and dose-limiting toxicities (DLT). Safety assessments included treatment-emergent adverse events (TEAEs) and cardiac safety (ultrasound cardiography/Doppler imaging, electrocardiogram, chest computed tomography, and cardiotoxicity serum biomarkers).Twelve patients (Cohort-1, n = 3; Cohort-2, n = 9) were enrolled and the most common types of cancer were pancreatic (n = 5) and lung cancer (n = 3). Seven patients (Cohort-1, n = 2; Cohort-2, n = 5) experienced possibly galunisertib-related TEAEs. The most frequent related TEAEs were brain natriuretic peptide increased (n = 2), leukopenia (n = 2), and rash (n = 2). No cardiovascular toxicities or other DLTs were reported. PK profile of galunisertib was consistent with the FHD study. Maximum plasma concentration was reached within 2 h post-dose, and the mean elimination half-life was 9 h.Galunisertib had an acceptable tolerability and safety profile in Japanese patients with advanced cancers.

Filtering

Case insensitive filtering will display rows if any text in any cell matches the filter term
Use simple literal full or partial string matches
Separate multiple filter terms with a space. Any order may be used (i. e. a b c and c b a are equivalent )
Filtering will only apply to rows that are already loaded on the page. Filtering has no impact on query parameters.
Use quotes to match on a longer phrase with spaces (i.e. "mtor c1483f")

Sorting

Generally, the default sort order for tables is set to be first column ascending; however, specific tables may set a different default sort order.
Click on any column header arrows to sort by that column
Hold down the Shift key and click multiple columns to sort by more than one column. Be sure to set ascending or descending order for a given column before moving on to the next column.
