Thank you, Yossi. Good morning, and thank you for joining us. I'm happy to be here today to discuss the progress Protalix has made over the past quarter. During the call, I will provide a corporate update and then turn the call over to Yossi to review the company's financials.
Starting first with our lead program, pegunigalsidase alfa, or PRX-102, for the treatment of Fabry disease, we have 2 updates. First, as everyone has seen, we expanded our partnership with Chiesi to include exclusive U.S. rights for the development and commercialization of PRX-102. Terms of the agreement included an upfront payment of $25 million, up to $20 million in development cost, additional up to $760 million in regulatory and commercial milestones and tiered royalties ranging from 15% to 40%.
With this influx of cash and additional development cost, Protalix is now funded through the readout of all of our studies for PRX-102. The more we work with Chiesi and learn about them and more they learn about the product and the market opportunity, the more they wanted to expand our existing relationship. We found Chiesi to be extremely dedicated to the field in general and to our program specifically, applying a lot of resources already in this clinical stage and long-term strategy as well. We believe Chiesi's recent expansion in the U.S. has well made them an ideal partner for PRX-102 in this territory as well. This expansion of the partnership allows the option for Protalix to, not only complete the trial without additional capital, but that is in such a way that we will meaningfully serve in the commercial success. The second piece of the news which could be potentially very good for our ongoing program is a drug guideline the FDA released last month regarding enzyme replacement therapies. We think that this changed the way that the FDA looks to a [ poor drug ] like PRX-102. With Chiesi, we will talk to advisor and decide if there is another potentially quicker that to market in the United States.
As enrolment continues across the study, we are beginning to see some preliminary data from BRIDGE study, pegunigals switch over study and planning to report data in the first half of next year. A reminder how it allows a study -- the BALANCE study will have interim data approximately 1 year after completion of the enrolment which we will press release. Our BRIGHT study, every 4-weeks, the infusion is also enrolling. In the coming quarter, we will provide guidance on when to expect interim data.
Also during the past quarter, we reported positive data from our Phase II trial of OPRX-106 in ulcerative colitis. We were very happy with the result which show mucosal improvement in 61 patients, mucosal healing in 33% of patient and clinical remission in 28% of patients. We believe that this is a very interesting drug candidate and during the remaining of the year, we plan to have a deep-dive to review the different path possible for us to move forward in development.
I will now turn call back to Yossi who will provide the financial overview.
