Corcept Therapeutics Incorporated (NASDAQ:CORT), a commercial-stage company engaged in the discovery and development of medications to treat severe endocrinologic, oncologic, metabolic and neurologic disorders by modulating the effects of the hormone cortisol, today reported its results for the quarter ended September 30, 2024.

Financial Results

"In the third quarter, we added more Korlym^® prescribers and more patients received Korlym treatment than ever before," said Joseph K. Belanoff, MD, Corcept's Chief Executive Officer. "Physicians are increasingly aware of hypercortisolism's true prevalence and of the poor health outcomes of patients who go untreated. Screening is becoming more common and the number of patients receiving appropriate care continues to increase. For patients and physicians who choose Korlym, our extensive system of support services is critical to optimizing the benefit of our medication."

Corcept's third quarter 2024 revenue was $182.5 million, compared to $123.6 million in the third quarter of 2023. Third quarter operating expenses were $135.9 million, compared to $92.4 million in the third quarter of 2023. Net income was $47.2 million in the third quarter of 2024, compared to $31.4 million in the same period last year.

The company increased its 2024 revenue guidance to $675 – $700 million.

Cash and investments were $547.6 million at September 30, 2024, compared to $492.5 million at June 30, 2024. The balance at September 30, 2024 reflects the acquisition of $23.4 million of common stock (870,000 shares) in the third quarter pursuant to the company's stock repurchase program, net exercise of employee stock options and net vesting of restricted stock grants.

Clinical Development

"Our clinical development programs have positioned us for a transformative fourth quarter," added Dr. Belanoff. "We are on track to submit our NDA for relacorilant as a treatment for patients with hypercortisolism (Cushing's syndrome) by year-end. We also expect to release data from (i) the treatment phase of our CATALYST study in patients with Cushing's syndrome, (ii) ROSELLA, our pivotal study in women with platinum-resistant ovarian cancer, and (iii) DAZALS, our study in patients with amyotrophic lateral sclerosis (ALS) by year-end."

Cushing's Syndrome

• Relacorilant for Cushing's syndrome – NDA submission expected this quarter
• GRACE – Pivotal Phase 3 trial of relacorilant in 152 patients with all etiologies of Cushing's syndrome – primary endpoint achieved in randomized withdrawal phase; open-label phase demonstrated clinically meaningful improvements in a broad range of hypercortisolism signs and symptoms; relacorilant was well-tolerated, with no cases of relacorilant-induced hypokalemia, endometrial hypertrophy or related vaginal bleeding, adrenal insufficiency or QT prolongation
• GRADIENT – Supportive trial data for NDA – Patients treated with relacorilant exhibited clinically meaningful improvements in a broad range of hypercortisolism signs and symptoms in randomized, double-blind, placebo-controlled, Phase 3 trial in 137 patients with Cushing's syndrome caused by adrenal gland pathology; relacorilant was well-tolerated, with a safety profile consistent with the GRACE study, including no cases of relacorilant-induced hypokalemia, endometrial hypertrophy or related vaginal bleeding, adrenal insufficiency or QT prolongation
• CATALYST – Treatment phase of randomized, double-blind, placebo-controlled study of Korlym in 136 patients with hypercortisolism and difficult-to-control type 2 diabetes; results expected this quarter

"GRADIENT's positive results in patients with Cushing's syndrome confirm relacorilant's promise as a significant medical advancement for the treatment of this deadly disease. As was true in the GRACE study, patients in GRADIENT who received relacorilant experienced clinically meaningful improvements in a broad range of hypercortisolism signs and symptoms, without suffering some of the serious adverse effects that can arise in patients taking currently approved treatments," said Bill Guyer, PharmD, Corcept's Chief Development Officer. "These data will be a powerful addition to relacorilant's NDA, which we plan to submit by year-end."

The pivotal Phase 3 GRACE trial is the basis for relacorilant's NDA in Cushing's syndrome and met its primary endpoint. Patients in GRACE's initial, open-label phase exhibited clinically meaningful and statistically significant improvements in hypertension, hyperglycemia and other symptoms experienced by patients with Cushing's syndrome. In the randomized withdrawal phase, GRACE met its primary endpoint and demonstrated that patients who remained on relacorilant maintained these improvements while those who received placebo saw a significant worsening in their signs and symptoms of hypercortisolism. Consistent with its known safety profile, relacorilant was well-tolerated in both phases of GRACE.

As part of relacorilant's NDA in Cushing's syndrome, the 22-week Phase 3 GRADIENT study supports the GRACE trial by providing further evidence of relacorilant's efficacy and safety profile. Patients treated with relacorilant in the GRADIENT study exhibited clinically meaningful and statistically significant improvements in hypertension, hyperglycemia, weight and body composition compared to baseline, while patients who received placebo did not. The trial's primary endpoint was the improvement in systolic blood pressure (SBP) compared to placebo with hyperglycemia, weight and body composition as secondary endpoints.

Patients who entered GRADIENT with hypertension and received relacorilant exhibited clinically meaningful and statistically significant improvements in mean SBP at 22 weeks (reduction of 6.6 mm Hg; p-value: 0.012), compared to baseline. Patients who received placebo did not (reduction of 2.1 mm Hg; p-value: ns), compared to baseline. The comparison between those who received relacorilant and placebo was not statistically significant. During the study, 5 patients who received placebo compared to 1 patient who received relacorilant required rescue therapy with anti-hypertension medications. To ensure accuracy, hypertension was measured by 24-hour ambulatory blood pressure monitoring.

GRADIENT patients with hyperglycemia who received relacorilant experienced clinically meaningful and statistically significant improvements at 22 weeks in glucose metabolism, including fasting glucose (placebo-adjusted reduction of 22.2 mg/dL; p-value: 0.002), area under the curve of the oral glucose tolerance test (placebo-adjusted reduction of 2.6 h*mmol/L; p-value: 0.046) and hemoglobin A1c (placebo-adjusted reduction of 0.3 percent; p-value: 0.019), compared to those who received placebo.

Patients in GRADIENT who received relacorilant experienced clinically meaningful and statistically significant improvements at 22 weeks in body weight (placebo-adjusted reduction of 3.9 kg; p-value: 0.0001) and both visceral adipose fat mass and volume (p-values: 0.018 and 0.016, respectively), compared to those who received placebo.

Relacorilant was well tolerated in GRADIENT, with side effects consistent with those seen in its Phase 2 and GRACE trials. Across all of these studies, the most common adverse events were mild-to-moderate nausea, edema, pain in extremities and back, and fatigue – all symptoms associated with the "cortisol withdrawal" many patients experience following surgery or start of medical therapy for Cushing's syndrome. Importantly, there were no relacorilant-induced instances of hypokalemia, relacorilant-induced endometrial hypertrophy or related vaginal bleeding, adrenal insufficiency or QT prolongation.

Complete results from the GRADIENT trial will be presented at a medical conference next year.

"We are also looking forward to results from the treatment phase of our CATALYST study by year-end," continued Dr. Guyer. "CATALYST is the largest and most rigorous study ever conducted of hypercortisolism in patients with difficult-to-control diabetes. CATALYST's prevalence results confirm there are many more patients with Cushing's syndrome than was previously assumed and the trial is poised to be a landmark study in the identification and treatment of patients with hypercortisolism. We are confident it will lead to better health outcomes for many patients who are struggling today."

Oncology

• ROSELLA – Enrollment completed in pivotal Phase 3 trial of relacorilant plus nab-paclitaxel in 381 patients with platinum-resistant ovarian cancer; results expected this quarter
• Early-stage prostate cancer – Enrollment continues in randomized, placebo-controlled, Phase 2 trial of relacorilant plus enzalutamide in patients with early-stage prostate cancer, conducted in collaboration with the University of Chicago

"Relacorilant has the potential to become the standard of care for patients with platinum-resistant ovarian cancer. If ROSELLA replicates the positive results of our large, controlled, Phase 2 study, it will constitute a major medical advance and serve as the basis for relacorilant's next NDA. We expect progression-free survival data, ROSELLA's primary endpoint, by the end of this year," said Dr. Guyer.

Amyotrophic Lateral Sclerosis (ALS)

• DAZALS – Enrollment completed in randomized, double-blind, placebo-controlled, Phase 2 trial of dazucorilant in 249 patients with ALS; results expected this quarter

"ALS is a dire disease, with few good treatment options. Our selective cortisol modulator dazucorilant showed great promise in an animal model of ALS, improving motor performance and reducing neuroinflammation and muscular atrophy. We expect data regarding DAZALS's primary endpoint – improvement in patients' ALS Functional Rating Scale-Revised (ALSFRS-R) score – by the end of this year. We hope DAZALS will lead to a much-needed advance for patients with ALS," said Dr. Guyer.

Metabolic Dysfunction-Associated Steatohepatitis (MASH)

• MONARCH – Enrollment continues in randomized, double-blind, placebo-controlled, Phase 2b trial of miricorilant in 120 patients with biopsy-confirmed MASH and in 75 patients with presumed MASH

"In our Phase 1b study, miricorilant reduced liver fat very rapidly, improved liver health and key metabolic and lipid measures, and was well-tolerated. We look forward to building on these promising results in our MONARCH study," said Dr. Guyer. "Miricorilant has the potential to greatly benefit the millions of patients with MASH."
