Thank you, Maria. My comments will address a few highlights from our financial results. Additional details can be found in the third quarter news release that we distributed earlier. Net loss for the third quarter ended September 30, 2019, was $49.5 million or $0.40 per share compared to $33.8 million or 0.36 per share for the third quarter 2018. Research and development expenses were $41.6 million for the third quarter of 2019, an increase of $13.7 million when compared to $27.9 million for the third quarter last year. The increase was primarily attributable to higher manufacturing costs resulting from increased capacity added to support enrollment in the pivotal and other clinical studies. The increase is also due to higher R&D personnel costs, including stock-based comp resulting from an increase in headcount as compared to the third quarter in 2018. General and administrative expenses were $10 million for the third quarter of 2019, an increase of $2.9 million when compared to the $7.1 million for the third quarter of 2018. The increase was primarily attributable to the increased personnel costs due to additional G&A employees added in 2019. Net loss for the nine months ended September 30, 2019 was $134 million or $1.08 per share as compared to a net loss of $91 million or $1.01 per share for the same period of 2018. Research and development expenses were $111.8 million for the nine months ended September 30, 2019, an increase of $39.4 million when compared to $72.4 million for the same period in 2018. The increase was primarily attributable to the reasons stated above for the quarter, namely additional manufacturing and clinical trial costs resulting from higher enrollment and increased personnel costs due to an increase employees as compared to the same period in 2018. General and administrative expenses were $30 million for the nine months ended September 30, 2019, an increase of $9.1 million compared to the $20.9 million for the same period in 2018. Again, the increase was primarily attributable to the reasons stated above namely higher personnel costs, including stock-based comp resulting from an increase in number of G&A employees. At September 30, 2019 the company held $367.3 million in cash, cash equivalents, short-term investments and restricted cash, as compared to $468.5 million at December 31, 2018. For the third quarter, the changing cash was $42.3 million, mainly from cash used in operations. At year-end, the company anticipates at the balance of cash, cash equivalents, short-term investments and restricted cash maybe between $310 million and $320 million. This month, in addition to SITC, we look forward to presenting at their credit Suisse healthcare conference in Phoenix. The Stifel 2019 health care conference in New York, the Jefferies Healthcare Conference in London. I will now turn the call over to the operator for questions. Operator?
