Transforming growth factor-beta (TGF-?) signaling plays an important role in the
fetal development of cardiovascular organs and in the repair mechanisms of the
heart. Hence, inhibitors of the TGF-? signaling pathway require a careful
identification of a safe therapeutic window and a comprehensive monitoring of the
cardiovascular system. Seventy-nine cancer patients (67 glioma and 12 solid
tumor) enrolled in a first-in-human dose study and received the TGF-? inhibitor
LY2157299 monohydrate (LY2157299) as monotherapy (n = 53) or in combination with
lomustine (n = 26). All patients were monitored using 2D echocardiography/color
and Spectral Doppler (2D Echo with Doppler) every 2 months, monthly
electrocardiograms, thorax computer tomography scans every 6 months, and monthly
serum brain natriuretic peptide (BNP), troponin I, cystatin C, high-sensitivity
C-reactive protein (hs-CRP). Administration of LY2157299 was not associated with
medically relevant cardiovascular toxicities, including patients treated
?6 months (n = 13). There were no increases of troponin I, BNP, or hs-CRP or
reduction in cystatin C levels, which may have been considered as signs of
cardiovascular injury. Blood pressure was generally stable during treatment.
Imaging with echocardiography/Doppler showed an increase in mitral and tricuspid
valve regurgitation by two grades of severity in only one patient with no
concurrent clinical symptoms of cardiovascular injury. Overall, this
comprehensive cardiovascular monitoring for the TGF-? inhibitor LY2157299 did not
detect medically relevant cardiac toxicity and hence supports the evaluation of
LY2157299 in future clinical trials.
