Regnite launched in July this year, in Japan. We are very excited to see the Astellas' efforts in launching that product, its 1,200 sales reps; they are making a big effort. They estimate about $2 million moderate-to-severe primary RLS patients in Japan, so we'll get our first indication of the sales for the third quarter in the fourth quarter when Astellas presents their financial results. We have a high-teen royalty from sales of the product in Japan.
As you know launches in Japan, the prescriptions are limited to 14 days. People have to come back every 14 days in the first year of the launch, so it may take off little slowly, but Astellas has been a great partner for us so far there.
Next, for this long is arbaclofen placarbil or AP. We have an upcoming big event, the completion of our Phase III study for the treatment of spasticity and multiple sclerosis patients. We anticipate the results of that study in the first quarter of next year. We hope to file an NDA for that product in the second half of next year using a 505(b)(2) process that we have agreed to with the FDA and we do have an SPA for that Phase III study.
Next furthers along is 279, and L-Dopa, prodrug for the treatment of advanced Parkinson's disease. We had some interesting feedback from the FDA in June of this year, where they agreed to a 505(b)(2) path gave us very specific guidance on what a pivotal study has to look like and we are taking some efforts to get an SPA and to do some work in preparation for Phase III, but we won't proceed with Phase III until we have a partner or a financial resources change.Finally, I think what has lot of investors excited as well as ourselves is an earlier stage product that started human studies recently and it is a fumarate-based product that we are potentially developing for the treatment of relapsing-remitting MS, and potentially psoriasis and it shares in common an active metabolite monomethyl fumarate, which is the same active metabolite that's found with the Biogen product BG-12 and the psoriasis product Fumaderm in Germany, and Phase I study the in-life phase has been completed and we expect the results of that study in October of this year.
