7.Market situation:
Brain stroke is one of several diseases that the medical community is
trying urgently to resolve. Each year, there are about 15 to 17 million
people in the world suffering stroke; among which, 80% of the patients are
ischemic. The current treatment for acute ischemic stroke (AIS) is a
thrombolytic agent named rt-PA. Unfortunately, the benefit of rt-PA is
limited due to its high risks involving hemorrhage and short treatment time
window, only 3%~5% AIS patients are treated with thrombolytics. Other than
thrombolytic agent, mechanical thrombectomy is another treatment options but
with limited clinical efficacy. Should LT3001 be presented with a desirable
safety profile, the drug can be applied either alone or in combination with
thrombectomy to the stroke patients within 24hr stroke onset, and the
potential market size could reach US$10.6 billion.
8.Any other matters that need to be specified:
According to the collaboration agreement between The Company and the
inventors of LT3001, the company will pay 5% of the license income if the
technology is licensed to a third part and 2% of the net sales revenue if
the product is marketed.
9.New drug development requires long process, vast investments and with
no guarantee in success which may pose investment risks.The investors
are advised to exercise caution and conduct thorough evaluation.:
