Thank you, Charlie. The strong results of our commercial business in the second quarter reflect the early return on our substantial investment to stimulate physicians to better recognize to treat hypercortisolism. In the second quarter, we saw a continued increase in the number of patients receiving Korlym in a number of physicians prescribing the medication. The business translation of more panic patients benefiting from Korlym treatment is a new record high in our quarterly revenue, we expect our growth to continue. Korlym is an excellent treatment for patients with Cushing’s syndrome, and there are many eligible patients who have yet to receive it. Leading endocrinologist increasingly believed that there are considerably more patients with Cushing's Syndrome than was once assumed. Results of our ongoing CATALYST study will likely provide further evidence to bolster this belief and equally likely believe physicians to begin to identify and provide effective treatment for a large group of patients with hypercortisolism, whose disease currently goes undiagnosed. We are confident in the growth potential of our Cushing's Syndrome business and are raising our 2023 revenue guidance range again, this time to $455 million to $470 million. We're also very excited by the potential of our clinical development programs. Since inception, our research and development efforts have built on the hypothesis that cortisol modulation can be a powerful therapeutic mechanism in many serious disorders. Our proprietary compounds modulate cortisol effects by binding to the glucocorticoid receptor or GR. The receptor which is activated when cortisol levels are high. They do not bind to the progesterone receptor, and don't cause some of Korlym’s, our approved products and the serious off-target effects. Interestingly, while our compounds modulate cortisol activity, without modulating progesterone activity, they are not identical. Some cross the blood brain barrier others do not. Some perform best in models of solid tumors. Others are more potent in models of metabolic disease. Some appear to be tissue specific, others have more global effects. These diverse qualities allow us to study a wide variety of disorders. Currently, we are conducting programs with three of our proprietary selected cortisol modulators, relacorilant, dazucorilant and miricorilant, in ovarian, adrenal and prostate cancer, ALS, NASH and of course, Cushing’s syndrome. We have additional compounds in clinical and preclinical development. In the next 12 months we expect data from our GRACE, GRADIENT and CATALYST studies, submission of an NDA for relacorilant in Cushing’s syndrome, completion of enrollment of our ROSELLA and DAZALS studies and initiation of Phase 2b trial of relacorilant in patients with NASH. This is a very exciting time for Corcept. We are evaluating relacorilant for the treatment of hypercortisolism in two Phase 3 trials, GRACE and GRADIENT. Relacorilant is a selective cortisol modulator. Like Korlym, it achieves its effect by competing with cortisol at the glucocorticoid receptor unlike, Korlym it does not it does not bind to the progesterone receptor PR for short, and so does not cause PR related side effects, including termination of pregnancy, endometrial thickening and vaginal bleeding, by different mechanism relacorilant also does not cause hypokalemia, low potassium, a serious side effects experienced by 44% of patients of patients in Korlym’s pivotal trial. Korlym induced hypokalemia is a leading cause of Korlym discontinuation. Relacorilant’s Phase 2 efficacy and safety data were compelling. Patients experience meaningful improvements in hypertension and glucose control, as well as in a variety of other signs and symptoms of Cushing's Syndrome. There were no relacorilant induced instances of endometrial thickening or vaginal bleeding, and no drug induced hypokalemia. The trial results were published in Frontiers in Endocrinology in July 2021. With enrollment in GRACE complete, we are focused on finishing the trial and preparing our NDA, which we plan to submit in the second quarter of 2024. Relacorilant has tremendous promise as a treatment for patients with all etiologies of endogenous Cushing's syndrome. And we are eager to make it available. Our second Phase 3 trial in hypercortisolism of GRADIENT is studying relacorilant effects to patients whose Cushing’s syndrome is caused by an adrenal adenoma or adrenal hyperplasia. Patients with this etiology of Cushing's Syndrome often experience less rapid decline, but their health outcomes are poor, including a higher risk of premature death. While we do not expect our NDA and Cushing's Syndrome to depend on data from GRADIENT, we do expect the study to produce valuable data about an etiology of Cushing's syndrome that affects many patients whose hypercortisolism frequently goes undiagnosed and untreated. I'm pleased to announce that our CATALYST study is progressing ahead of schedule. CATALYST is a 1,000 patient Phae 4 trial examining the prevalence of hypercortisolism in patients with typical to control type 2 diabetes. Patients diagnosed with hypercortisolism in a CATALYST study, we choose to enter a randomized, double blind placebo controlled study of Korlym, many independent studies conducted over the last 15 years have found that the prevalence of hypercortisolism in patients with type 2 diabetes is substantially higher than in the general population. The most prominent diabetologist in the United States help us design and are participating in CATALYST, which will be the largest study of its time. We have received very positive feedback from leading endocrinologist regarding this study, and expect to complete enrollment in the fourth quarter a bit ahead of our previous estimate. Our oncology program is testing three anti-cancer mechanisms first postulated by investigators at the University of Chicago and later confirmed by other prominent researchers. One mechanism is increasing apoptosis, the program cell death that chemotherapy is meant to induce in solid tumors. Cortisol works against the beneficial effects of chemotherapy by suppressing apoptosis. And our successful control Phase 2 trial in women with platinum resistant ovarian cancer. The addition of our selective cortisol modulator relacorilant enhance the effect of chemotherapy, likely by blunting cortisol’s anti-apoptotic effect. Relacorilant provided meaningful benefit to many of the women in our study. While these women's disease have progressed on to more previous lines of treatment, including previous Taxanes, relacorilant appear to re-sensitize the disease to chemo therapies beneficial effects to some women, those who received relacorilant intermittently the day before the day of and the day after they receive nab-paclitaxel exhibit a statistically significant improvement in progression free survival and duration of response compared to the group who received nab-paclitaxel monotherapy. Women in the intermittent and relacorilant group also live longer than does the comparator arm with a p-value that approach statistical significance. Our analysis to date indicates the 29% of the patients who took intermittent relacorilant were alive two years after study start versus only 14% who took nab-paclitaxel alone. Just as important, the women who receive relacorilant plus nab-paclitaxel experienced no additional side effect burden compared to those who receive nab-paclitaxel alone. The results from this study were recently published in the prestigious Journal of Clinical Oncology. Results have also been featured in podium presentations at the 2021 and 2022 European Society for Medical Oncology, ESMO meeting and at the 2022 American Society of Clinical Oncology, ASCO Annual Meeting. ROSELLA, our confirmatory pivotal Phase 3 trial in platinum resistant ovarian cancer is enrolling patients. ROSELLA designed closely tracks a Phase 2 study and its goal was simply to replicate a positive Phase 2 results in a larger group. Plan enrollments of 360 women randomized one to one to receive the relacorilant plus nab-paclitaxel or nab-paclitaxel alone. The primary endpoint is progression free survival with overall survival a key secondary endpoint. We are conducting this study in collaboration with leading clinicians from the gynecological oncology group in the United States and the European Network of Gynecological Oncology Trials Group in Europe. We are on track to complete enrollment by the end of the year. Leading gynecological oncologists have told us that in their view, relacorilant’s potential benefit, improved progression free and overall survival without increased side effect burden would constitute an important medical advance and that relacorilant plus nab-paclitaxel has the potential to become a new standard of care in women with platinum resistant ovarian cancer. Second mechanism by which cortisol modulation improve useful is by blocking an important tumor growth pathway. Cortisol stimulation is a major reason why patients with prostate cancer treated with a widely prescribed androgen receptor antagonist Enzalutamide eventually experienced resurgent disease, deprived of androgen stimulation, their tumor switched to cortisol activity to stimulate growth. Our hypothesis is that adding a cortisol modulator to androgen deprivation therapy and close this tumor escape route. Our collaborators at the University of Chicago plan to begin a randomized placebo controlled Phase 2 trial of relacorilant plus Enzalutamide in patients with prostate cancer before these patients have had an initial prostatectomy this quarter. Third therapeutic mechanism seeks to treat tumors by enhancing the body's immune response. Cortisol suppresses the immune system, which may blunt the effectiveness of cancer therapies intended to stimulate the immune system. Our hypothesis is that adding a cortisol modulator to immunotherapies such as checkpoint inhibitors may enhance the effectiveness of these therapies. We are conducting a Phase 1b trial of relacorilant plus the PD1 checkpoint inhibitor pembrolizumab in patients with advanced adrenal cancer, these tumors produce excess cortisol. pembrolizumab is rarely effective as monotherapy in treating this form of adrenal cancer. ALS commonly known as Lou Gehrig's Disease is a devastating illness with an urgent need for better treatment. DAZALS , our 198 patient randomized double blind placebo controlled Phase 2 trial of dazucorilant in patients with ALS is briskly enrolling patients. dazucorilant is a selective cortisol modulator that has shown great promise in animal models of ALS, improving motor performance and reducing neural inflammation and muscular atrophy. We are conducting this important study in collaboration with TRICALS, a leading ALS academic consortium in Europe. We recently added clinical trials right in the United States, and are on track to complete enrollment in DAZALS by early next year. Finally, I'll turn to our program in NASH, a serious liver disorder that afflicts millions of patients in the United States. Miricorilant an oral medication continues to demonstrate great promise as a treatment for NASH. In our prior NASH studies, patients who received 600 milligrams or 900 milligrams of miricorilant daily exhibited large rapid reductions in liver fat, but also substantial albeit transient elevations of the liver enzymes, ALP and ASD. The improvements in liver fat in these patients was greater and occurred much more rapidly than we had expected, and is rarely seen over any period of treatment. Our ongoing Phase 1b dose timing study, which evaluated a range of doses and dosing schedules of miricorilant found that patients who receive just 100 milligrams of miricorilant orally twice a week for 12 weeks experience an approximately 30% reduction in liver fat and showed improvements in liver enzymes and markers of liver disease. These patients also experienced improvements in key metabolic to lipid measures such as Homa IR, serum triglycerides, and LDL. Importantly, miricorilant was very well tolerated. We plan to submit these results for presentation at a scientific conference and will initiate a Phase 2b trial in the fourth quarter. In conclusion, we are extremely optimistic about the future of Corcept, our Cushing’s Syndrome business has tremendous growth potential and generates substantial profits even as we invest in R&D advancing development programs. We are again raising our revenue guidance for this year and anticipate growth for years to come. Our CATALYST study holds great promise, as the data generated will help physicians to improve the screening and treatment of patients with difficult to control diabetes is caused by hypercortisolism, a population whose Cushing’ Syndrome frequently goes undiagnosed. For these patients, hypercortisolism is their disease and diabetes are a symptom of their hypercortisolism. Our development programs are generating increasing evidence and validates our long held belief the cortisol modulation has the potential to treat a wide range of diseases. Reducing cortisol activity is a straightforward and effective way to treat Cushing's Syndrome and can offer substantial benefits to patients with other serious disorders. Ovarian cancer, ALS and NASH are current examples, but there will be others. In addition to relacorilant, dazucorilant and miricorilant, we have many other proprietary selective cortisol modulators in our portfolio with potentially very different clinical attributes. In the next 12 months, we will see data from our GRACE, GRADIENT and CATALYST studies in Cushing’s Syndrome. We will submit relacorilant NDA in Cushing’s Syndrome, and we'll complete enrollment and large controlled studies of platinum resistant ovarian cancer and ALS. We will also begin a Phase IIb study in patients with NASH. As I said, this is an exciting time for Corcept. I thank our dedicated creative employees and loyal investors for making that possible. I'll stop here for questions.
