• The Endogenous Cushing’s Syndrome market is expected to surge due to the disease’s increasing prevalence and awareness during the forecast period. Furthermore, launching various multiple-stage Endogenous Cushing’s Syndrome pipeline products will significantly revolutionize the Endogenous Cushing’s Syndrome market dynamics.
• Research by Scaroni et al. (2023) indicates that Cushing syndrome occurs at an incidence rate of 1.5 per 1,000,000 individuals annually and has a prevalence of around 60 per 1,000,000 individuals in Europe. In about 80% of cases, Cushing syndrome is caused by adrenocorticotrophic hormone (ACTH) hypersecretion, resulting in ACTH-dependent Cushing syndrome.
• Cushing’s syndrome can be caused by either ACTH-dependent (80% of cases) or ACTH-independent (20% of cases) factors. The latter is primarily attributed to benign adrenal tumors (60%) or malignant tumors (40%). ACTH overproduction can either originate from the pituitary (85% of cases) or result from ectopic tumor secretion (15% of cases). The term “Cushing’s disease” is specifically used to refer to ACTH-secreting pituitary tumors.

Endogenous Cushing’s Syndrome Overview
Endogenous Cushing’s Syndrome is a rare hormonal disorder caused by the body’s overproduction of cortisol, a hormone produced by the adrenal glands. This overproduction can result from tumors or abnormalities in the pituitary gland (Cushing’s disease), adrenal glands, or other parts of the body that cause excessive cortisol secretion. It contrasts with exogenous Cushing’s syndrome, which results from external sources like long-term use of corticosteroid medications.

Relacorilant Effectively Manages Cortisol Effects in Cushing’s Patients

Posted on May 12, 2018 by MaryO

Relacorilant, an investigational therapy developed by Corcept Therapeutics, may effectively manage the effects of excess cortisol in patients with Cushing’s syndrome, interim data from an ongoing Phase 2 trial show.

In particular, the treatment significantly improved sugar tolerance and the levels of osteocalcin, a bone growth biomarker  commonly suppressed by excess cortisol.

Corcept announced in a press release that the trial (NCT02804750) has completed patient enrollment. Results from the first patients will be presented during the upcoming 27th American Association of Clinical Endocrinologists (AACE) annual meeting, May 16-20 in Boston. Full data is expected by the third quarter of 2018.

Relacorilant, also known as CORT125134, was designed to prevent the effects of excess cortisol by blocking one of its receptors, the glucocorticoid receptor.

In a Phase 1 trial with healthy volunteers, multiple doses of relacorilant had a similar effect as Korlym (mifepristone) — an approved medicine for Cushing’s patients — without its known side effects.

In addition to the early efficacy data, the study showed that the treatment was generally safe and well-tolerated by the patients, with adverse events reportedly mild in severity.

These findings supported the launch of the Phase 2 trial in patients with Cushing’s syndrome. In the trial, roughly 30 patients are receiving escalating doses of relacorilant for a total of 12 weeks.

Patients were divided into two groups. The first group, which includes 17 patients, receives the lowest dose — 100 mg/day of relacorilant for four weeks, followed by 150 mg/day for four weeks, and then 200 mg/day for the last four weeks. The second group, called the high-dose cohort, is treated with a similar regimen but with a starting dose of 250 mg/day and a final dose of 350 mg/day.

Patients in the low-dose group had a significant improvement in their glucose tolerance and a 60% increase in blood osteocalcin.

In addition, the treatment reduced the blood pressure in 45% of patients with uncontrolled high blood pressure from cortisol excess. Importantly, the results after 12 weeks of relacorilant were similar to those seen after six months of Korlym treatment.

Safety data continues to show a positive profile, with no evidence of serious adverse effects and no affinity toward the progesterone receptor, which is a major drawback of Korlym.

“Relacorilant’s clinical results are striking because the doses these patients received were the study’s lowest. We did not expect patients to experience any meaningful clinical benefit, but they clearly did,” Robert S. Fishman, MD, chief medical officer of Corcept, said in the release. “We look forward to presenting data from these low-dose patients at the AACE meeting next week. With the trial’s final, high-dose cohort fully enrolled, we will have final data in the third quarter.”

Supported by these preliminary data, Corcept has accelerated the preparations for a Phase 3 trial on relacorilant in Cushing’s syndrome patients.

Cortisol Modulator Shows Early Signs of Safety, Efficacy in Healthy Volunteers

Posted on October 11, 2017 by MaryO

The glucocorticoid receptor antagonist CORT125134 is safe and has shown preliminary signs of efficacy in healthy volunteers participating in a Phase 1 trial, say researchers in England.

Their study, “Assessment of Safety, Tolerability, Pharmacokinetics, and Pharmacological Effect of Orally Administered CORT125134: An Adaptive, Double-Blind, Randomized, Placebo-Controlled Phase 1 Clinical Study,” appeared in the journal Clinical Pharmacology in Drug Development.”

Cortisol signaling is indirectly controlled by the glucocorticoid receptor (GR). When cortisol binds the GR, the receptor becomes activated and migrates to the nucleus, where it regulates the expression of many genes. This influences a myriad of processes, including inflammation, immune response and brain function.

CORT125134, also known as relacorilant, is being developed by Corcept Therapeutics of Menlo Park, California, for Cushing’s disease patients and others who may benefit from it. The drug is a GR antagonist, blocking the receptor’s activity.

In order to evaluate the safety and tolerability of CORT125134, and learn how it behaves in the body, Corcept researchers conduced a Phase 1 trial in healthy subjects.

The British study, conducted at the Quotient Clinical in Nottingham, included 81 adults who received a single ascending-dose of CORT125134 or placebo, and 48 subjects who received multiple-ascending doses of the drug versus placebo.

Single doses were tested in nine distinct groups. Six tested six different doses of CORT125134, one tested a 150 mg dose in subjects receiving a high-fat meal, and two groups included patients receiving prednisone (a well-known GR activator), prednisone plus Korlym (mifepristone), or prednisone plus CORT125134.

Korlym is a medicine approved for Cushing’s  patients with high blood sugar levels due to high cortisol in circulation. But the drug targets the progesterone receptor and is associated with side effects like pregnancy termination and irregular vaginal bleeding.

Multiple doses, given for up to 14 days, were tested in four additional cohorts. Researchers observed that CORT125134 was rapidly absorbed and eliminated, presenting a suitable profile for once-daily dosing.

Efficacy was determined by CORT125134’s ability to counteract the effects of prednisone. In addition, a single dose of 500 mg or multiple dosing with 250 mg had similar effects as those seen with 600 mg of Korlym — the therapeutic dose used for Cushing’s treatments.

Most common treatment-related adverse events reported in the single-ascending dose part of the study were nausea, vomiting and thirst; most were mild. In those given multiple-ascending doses, adverse events included mild musculoskeletal and connective tissue disorders, as well as gastrointestinal system disorders.

Multiple 500 mg doses exceeded the maximum tolerated dose, as it led to musculoskeletal symptoms that forced researchers to stop treatment.

“This first-in-human study has demonstrated that CORT125134 is well tolerated following single doses up to 500 mg and repeated doses up to 250 mg once daily for 14 days,” researchers wrote. “Pharmacological activity was confirmed following the administration of a single 500-mg dose and daily administration of 250 mg.”

Corcept is now enrolling participants into a Phase 2 open-label trial (NCT02804750) to evaluate CORT125134 in patients with Cushing’s syndrome. This trial is being conducted in the United States and Europe and will include 80 participants. Top-line results are expected in the first quarter of 2018.

Promising Pre-Clinical and Phase 1 Data Support Advance of Selective Cortisol Modulator CORT125134 as Potential Treatment for Cushing’s Syndrome and Solid-Tumor Cancers

Posted on April 30, 2016 by MaryO

MENLO PARK, CA–(Marketwired – Apr 28, 2016) –  Corcept Therapeutics Incorporated (NASDAQ: CORT), a pharmaceutical company engaged in the discovery, development and commercialization of drugs that treat severe metabolic, oncologic and psychiatric disorders by modulating the effects of cortisol, today released data supporting the clinical advancement of its proprietary, selective cortisol modulator, CORT125134. The company has begun recruiting patients for a Phase 1/2 trial of the compound to treat patients with solid-tumor cancers. It also expects to begin recruiting patients for a Phase 2 study of CORT125134 to treat patients with Cushing’s syndrome this quarter.

“Advancing CORT125134 is an important step in protecting and extending our growing Cushing’s syndrome franchise and in developing cortisol modulation for a wide range of other serious diseases,” said Joseph K. Belanoff, MD, Corcept’s Chief Executive Officer. “This selective cortisol modulator has shown great promise. We are optimistic that, for some patients with Cushing’s syndrome, CORT125134 may be even better than our approved product, Korlym® — just as effective, but without the side effects associated with Korlym’s affinity for the progesterone receptor. Equally important, we look forward to investigating its potential as a treatment for solid-tumor cancers.”

CORT125134 is the lead compound in Corcept’s proprietary portfolio of selective cortisol modulators. It is a non-steroidal competitive antagonist of the glucocorticoid receptor (GR) that does not bind to the body’s other hormone receptors, including the progesterone receptor (PR). Korlym’s interaction with PR results in termination of pregnancy and can cause endometrial thickening and irregular vaginal bleeding in some women. CORT125134 is proprietary to Corcept and is protected by composition of matter and method of use patents extending to 2033.

Advancement to Phase 2 Trials Supported by Positive Pre-Clinical and Phase 1 Data
“The data generated so far make this compound a promising candidate to treat both Cushing’s syndrome and, potentially, a number of solid-tumor cancers,” said Hazel Hunt, Ph.D., Corcept’s Vice President of Research. “Its Phase 1 data showed that it shares Korlym’s potent affinity for GR, one of the receptors to which cortisol binds. Our clinical testing showed that it can prevent the effects of the steroid prednisone, a commonly-used synthetic GR agonist. Preventing the effects of prednisone is a very important finding, as it mirrors the essential quality of an effective medical treatment for patients with Cushing’s syndrome.”

Corcept’s Phase 1 trial of CORT125134 enrolled 124 healthy volunteers. GR antagonism was tested by measuring CORT125134’s ability to modulate prednisone’s effects on serum osteocalcin, white blood cell counts, glucose metabolism and expression of the FKBP5 gene — a marker of GR activation. With respect to all parameters, CORT125134 was as potent a modulator of prednisone’s activity as Korlym (see Figure 1; p value < 0.0003).

Pharmacokinetic data indicate that CORT125134 is suitable for once-daily dosing.

“Positive Phase 1 data, together with encouraging pre-clinical results, prompted us to advance CORT125134 as a treatment for Cushing’s syndrome as well as a treatment for cancer,” continued Dr. Hunt. “Substantial pre-clinical and clinical research suggests that cortisol modulation increases the effectiveness of chemotherapy in some solid-tumor cancers. Pre-clinical data suggest that CORT125134 may be even more potent than Korlym in treating some tumor types.”

Corcept and investigators at the University of Chicago have studied the effectiveness of CORT125134 in transgenic mouse models of triple-negative breast cancer (TNBC) and castration-resistant prostate cancer. Mice implanted with TNBC tumor cells were treated with a combination of paclitaxel and CORT125134. Mifepristone (the active ingredient in Korlym) in combination with paclitaxel served as a positive control. As expected, the combination of mifepristone and paclitaxel significantly slowed tumor progression. However, the combination of CORT125134 and paclitaxel slowed it even more (see Figure 2; p value = 0.0004). In a similar experiment, castrated mice seeded with prostate cancer tumor cells were treated with either mifepristone or CORT125134. The outcome was comparable to the TNBC study: When combined with castration (which in humans would be achieved pharmacologically by the administration of an androgen receptor antagonist such as enzalutamide), mifepristone retarded tumor progression, but CORT125134 had an even more pronounced effect (see Figure 3; p value = 0.037).

CORT125134 may also enhance the efficacy of immune-modulation therapy. In an animal model of colon cancer, the addition of CORT125134 to PD-1 monotherapy significantly slowed tumor progression (see Figure 4; p value = 0.013):

Oncology Trial Design
This trial’s initial phase will investigate nab-paclitaxel in combination with CORT125134 to treat any solid-tumor cancer susceptible to treatment with nab-paclitaxel. (“Nab-paclitaxel” is the generic name for Celgene’s drug, Abraxane®.) Once a maximum tolerated dose is identified, Corcept plans to open one or more expansion cohorts, each containing 20 patients, to test the combination’s efficacy in one or more of the solid-tumor cancers studied in the dose-finding phase. Possible target indications include TNBC, castration-resistant prostate cancer, ovarian cancer, pancreatic cancer and sarcoma. Other dose-finding cohorts may be enrolled to study CORT125134 in combination with different companion therapeutic agents, including PD-1 inhibitors.

The trial is open-label and will be conducted at sites in the United States, the first of which is open and has begun screening patients.

“That we are advancing the same selective cortisol modulator as a treatment for both a metabolic disease and one or more oncologic indications is a testament to the broad therapeutic potential of cortisol modulation,” said Robert S. Fishman, MD, Corcept’s Chief Medical Officer. “We are excited to start these trials.”

Cushing’s Syndrome Trial Design
This Phase 2 trial of CORT125134 will enroll 30 patients with endogenous Cushing’s syndrome. Patients will be assigned to a low- or high-dose group and will receive CORT125134 for 12 weeks, with up-titration possible in each group at weeks four and eight. The trial will be open label. Study centers will be located in both the European Union and the United States.

About Korlym®
Korlym modulates the effect of cortisol at GR, one of the two receptors to which cortisol binds, thereby inhibiting the effects of excess cortisol in patients with Cushing’s syndrome. Since 2012, Corcept has made Korlym available as a once-daily oral treatment of hyperglycemia secondary to endogenous Cushing’s syndrome in adult patients with glucose intolerance or diabetes mellitus type 2 who have failed surgery or are not candidates for surgery. Korlym was the first FDA-approved treatment for that illness and the FDA has designated it as an Orphan Drug for that indication.

Endogenous Cushing’s syndrome is caused by prolonged exposure of the body’s tissues to high levels of the hormone cortisol and is generated by tumors that produce cortisol or ACTH. Cushing’s syndrome is an orphan indication that most commonly affects adults aged 20-50. An estimated 10-15 of every one million people are newly diagnosed with this syndrome each year, resulting in over 3,000 new patients annually in the United States. An estimated 20,000 patients in the United States have Cushing’s syndrome. Symptoms vary, but most people have one or more of the following manifestations: high blood sugar, diabetes, high blood pressure, upper body obesity, rounded face, increased fat around the neck, thinning arms and legs, severe fatigue and weak muscles. Irritability, anxiety, cognitive disturbances and depression are also common. Cushing’s syndrome can affect every organ system in the body and can be lethal if not treated effectively.

About Triple-Negative Breast Cancer
Triple-negative breast cancer is a form of the disease in which the three receptors that fuel most breast cancer growth — estrogen, progesterone and the HER-2/neu gene — are not present. Because the tumor cells lack the necessary receptors, treatments that target estrogen, progesterone and HER-2 receptors are ineffective. In 2013, approximately 40,000 women were diagnosed with TNBC. It is estimated that more than 75 percent of these women’s tumor cells expressed the GR receptor to which cortisol binds. There is no FDA-approved treatment and neither a targeted treatment nor an approved standard chemotherapy regimen for relapsed TNBC patients exists.
