So as far as the prevalence of CLL is concerned, CLL is considered the most common blood malignancy in the elderly population. And 21,000 new cases of CLL are diagnosed per year here in this country. And the patients with CLL, it's a slow-growing indolent cancer, so patients live long. So even though 21,000 doesn't seem like a big number, these patients live long and obviously add to the pool of patients with CLL. The annual mortality rate is around 4,500. So overall, there's a net gain per year of patients with CLL. So we have a fair number of patients with CLL in this country, but still accounts for less than 1% of all the cancers. Even despite the number of patients that we have in the United States, it is still considered a rare cancer. Chronic lymphocytic leukemia is the most common leukemia in the United States and in the Western world, in Europe as well. And it's estimated that there are about 20,000 new cases of CLL in the past year, or in 2024.
