The Cushings Disease Treatment Market To Be Consistent In The Next 10 Years

Cushing disease is caused by tumour in the pituitary gland which leads to excessive secretion of a hormone called adrenocorticotrophic (ACTH), which in turn leads to increasing levels of cortisol in the body. Cortisol is a steroid hormone released by the adrenal glands and helps the body to deal with injury or infection.

Increasing levels of cortisol increases the blood sugar and can even cause diabetes mellitus. However the disease is also caused due to excess production of hypothalamus corticotropin releasing hormone (CRH) which stimulates the synthesis of cortisol by the adrenal glands. The condition is named after Harvey Cushing, the doctor who first identified the disease in 1912. Cushing disease results in Cushing syndrome.

Cushing syndrome is a group of signs and symptoms developed due to prolonged exposure to cortisol. Signs and symptoms of Cushing syndrome includes hypertension, abdominal obesity, muscle weakness, headache, fragile skin, acne, thin arms and legs, red stretch marks on stomach, fluid retention or swelling, excess body and facial hair, weight gain, acne, buffalo hump, tiredness, fatigue, brittle bones, low back pain, moon shaped face etc. Symptoms vary from individual to individual depending upon the disease duration, age and gender of the patient.

Crinetics Pharmaceuticals’ Oral ACTH Antagonist, CRN04894, Demonstrates Pharmacologic Proof-of-Concept with Dose-Dependent Cortisol Suppression in Single Ascending Dose Portion of Phase 1 Study

SAN DIEGO, CA, USA I August 10, 2021 I Crinetics Pharmaceuticals, Inc. (Nasdaq: CRNX), a clinical stage pharmaceutical company focused on the discovery, development, and commercialization of novel therapeutics for rare endocrine diseases and endocrine-related tumors, today announced positive preliminary findings from the single ascending dose (SAD) portion of a first-in-human Phase 1 clinical study with CRN04894 demonstrating pharmacologic proof-of-concept for this first-in-class, investigational, oral, nonpeptide adrenocorticotropic hormone (ACTH) antagonist that is being developed for the treatment of conditions of ACTH excess, including Cushing’s disease and congenital adrenal hyperplasia.

“ACTH is the central hormone of the endocrine stress response. Even though we’ve known about its clinical significance for more than 100 years, there has never been an ACTH antagonist available to intervene in diseases of excess stress hormones. This is an important milestone for the field of endocrinology and for our company,” said Scott Struthers, Ph.D., founder and chief executive officer of Crinetics. “I am extremely proud of our team that conceived, discovered and developed CRN04894 this far. This is the second molecule to emerge from our in-house discovery efforts and demonstrate pharmacologic proof of concept. I am very excited to see what it can do in upcoming clinical studies.”

The 39 healthy volunteers who enrolled in the SAD cohorts were administered oral doses of CRN04894 (10 mg to 80 mg, or placebo) two hours prior to a challenge with synthetic ACTH. Analyses of basal cortisol levels (before ACTH challenge) showed that CRN04894 produced a rapid and dose-dependent reduction of cortisol by 25-56%. After challenge with a supra-pathophysiologic dose of ACTH (250 mcg), CRN04894 suppressed cortisol (as measured by AUC) up to 41%. After challenge with a disease-relevant dose of ACTH (1 mcg), CRN04894 showed a clinically meaningful reduction in cortisol AUC of 48%. These reductions in cortisol suggest that CRN04894 is bound with high affinity to its target receptor on the adrenal gland and blocking the activity of ACTH. CRN04894 was well tolerated in the healthy volunteers who enrolled in these SAD cohorts and all adverse events were considered mild.

“We are very encouraged by these single ascending dose data which clearly demonstrate proof of ACTH antagonism with CRN04894 exposure in healthy volunteers,” stated Alan Krasner, M.D., chief medical officer of Crinetics. “We look forward to completing this study and assessing results from the multiple ascending dose cohorts. As a clinical endocrinologist, I recognize the pioneering nature of this work and eagerly look forward to further understanding the potential of CRN04894 for the treatment of diseases of ACTH excess.”

About the CRN04894-01 Phase 1 Study
Crinetics is enrolling healthy volunteers in this double-blind, randomized, placebo-controlled Phase 1 study of CRN04894. Participants will be divided into multiple cohorts in the single ascending dose (SAD) and multiple ascending dose (MAD) phases of the study. In the SAD phase, safety and pharmacokinetics are assessed. In addition, pharmacodynamic responses are evaluated before and after challenges with injected synthetic ACTH to assess pharmacologic effects resulting from exposure to CRN04894. In the MAD phase, participants will be administered placebo or ascending doses of study drug daily for 10 days. Assessments of safety, pharmacokinetics and pharmacodynamics will also be performed after repeat dosing.

About CRN04894
Adrenocorticotropic hormone (ACTH) is synthesized and secreted by the pituitary gland and binds to melanocortin type 2 receptor (MC2R), which is selectively expressed in the adrenal gland. This interaction of ACTH with MCR2 stimulates the adrenal production of cortisol, a stress hormone that is involved in the regulation of many systems. Cortisol is involved for example in the regulation of blood sugar levels, metabolism, inflammation, blood pressure, and memory formulation, and excess adrenal androgen production can result in hirsutism, menstrual dysfunction, infertility in men and women, acne, cardiometabolic comorbidities and insulin resistance. Diseases associated with excess of ACTH, therefore, can have significant impact on physical and mental health. Crinetics’ ACTH antagonist, CRN04894, has exhibited strong binding affinity for MC2R in preclinical models and demonstrated suppression of adrenally derived glucocorticoids and androgens that are under the control of ACTH, while maintaining mineralocorticoid production.

About Cushing’s Disease and Congenital Adrenal Hyperplasia
Cushing’s disease is a rare disease with a prevalence of approximately 10,000 patients in the United States. It is more common in women, between 30 and 50 years of age. Cushing’s disease often takes many years to diagnose and may well be under-diagnosed in the general population as many of its symptoms such as lethargy, depression, obesity, hypertension, hirsutism, and menstrual irregularity can be incorrectly attributed to other more common disorders.

Congenital adrenal hyperplasia (CAH) encompasses a set of disorders that are caused by genetic mutations that result in impaired cortisol synthesis with a prevalence of approximately 27,000 patients in the United States. This lack of cortisol leads to a loss of feedback mechanisms and results in persistently high levels of ACTH, which in turn causes overstimulation of the adrenal cortex. The resulting adrenal hyperplasia and over-secretion of other steroids (particularly androgens) and steroid precursors can lead to a variety of effects from improper gonadal development to life-threatening adrenal crisis.

Experts offer Recommendations for Management of Pituitary Tumors

 

An international panel reached consensus for pre- and postoperative endocrine testing to manage adults undergoing transsphenoidal surgery, including measurement of prolactin and insulin-like growth factor I levels for all pituitary tumors.

In adults and children, transsphenoidal surgery represents the cornerstone of management for most large or functioning sellar lesions with the exception of prolactinomas, Maria Fleseriu, MD, FACE, an Endocrine Today Editorial Board Member, professor of medicine and neurological surgery and director of the Pituitary Center at Oregon Health & Science University in Portland, and colleagues wrote in Pituitary. Endocrine evaluation and management are an essential part of perioperative care; however, the details of endocrine assessment and care are not universally agreed on.

“Perioperative management of patients undergoing pituitary surgery is fascinating, as it involves many specialties — endocrinology, neurosurgery and ENT — and patients also get discharged very quickly in some countries, such as the United States,” Fleseriu told Healio. “At the start of the COVID-19 pandemic, the Physician Education Committee of the Pituitary Society, comprised of members from four continents, met to discuss a more streamlined process for workup before and after surgery for patients undergoing pituitary surgery. We have noticed big differences in management, but also some common themes, and decided to have a formal evaluation using a Delphi consensus and a much larger representation, with members from five continents.”

Building consensus

The task force behind the project, co-led by Nicholas A. Tritos, MD, DSc, associate professor of medicine at Harvard Medical School, and Pouneh K. Fazeli, MD, MPH, director of the neuroendocrinology unit and associate professor of medicine at University of Pittsburgh School of Medicine, created 35 questions and invited 55 pituitary endocrinologists to answer the questions in two Delphi rounds. Participants rated their extent of agreement with statements pertaining to perioperative endocrine evaluation and management, using a Likert-type scale.

Strong consensus, defined as at least 80% of panelists rating their agreement as 6 to 7 on a scale from 1 to 7, was achieved for 24 of 35 items. Less strict agreement, defined as ratings of 5 to 7, was reached for 31 of 35 items.

There were several significant findings, Fleseriu said.

Despite uncertainty in previous guidelines, panelists reached consensus to measure serum IGF-I for all patients with pituitary tumors preoperatively to ensure proper diagnosis of growth hormone excess, Fleseriu said.

“This is important because patients with GH-secreting adenomas do not always present with classic manifestations of acromegaly, require additional evaluation for comorbidities and postoperatively may benefit from further medical therapy or other adjuvant treatment,” Fleseriu said.

Panelists also expressed agreement on preoperative administration of glucocorticoid and thyroid hormone replacement for patients with diagnosed deficiencies, as well as perioperative use of stress-dose glucocorticoid coverage for patients with known or suspected hypoadrenalism, but not for all patients undergoing transsphenoidal surgery. Panelists also agreed on postoperative monitoring of serum sodium and cortisol and the use of desmopressin on-demand, required to control hypernatremia and/or polyuria, for patients with central diabetes insipidus.

“Agreement was achieved on postoperative monitoring of endocrine function, including morning serum cortisol in patients with Cushing’s disease, as well as serum IGF-I in patients with acromegaly,” Fleseriu said.

More research needed

Panelists did not reach consensus for a minority of items, representing areas where further research is needed, including measuring serum prolactin in dilution for all patients with large macroadenomas, Fleseriu said.

“Prolactin immunoassays can be susceptible to the ‘hook effect’ artifact, which may lead to substantial underreporting of prolactin values in sera containing very high prolactin concentrations, thus having important implications for patient management,” Fleseriu said. “Newer automated immunoassay platforms are likely to detect the hook effect; however, this may not be the case in older assays, which are still in use in many countries or laboratories. Therefore, especially when surgery is performed at an institution where automated assays are available to detect hook effect, yet patient workup has been carried out at an outside laboratory, additional lab workup might be needed. We envision this scenario can occur more often with the widespread use of telemedicine and endocrine testing being carried out at a distant laboratory.”

Additionally, there was a lack of consensus regarding preoperative testing for hypercortisolism in all patients with an apparently nonfunctioning pituitary adenoma. “This might reflect concern about false-positive results of endocrine testing in some individuals,” Fleseriu said. “On the other hand, published data suggest that some patients with Cushing’s disease may lack typical symptoms and signs and can present with an incidentally found sellar mass.”

Panelists did not reach consensus on items concerning preoperative medical therapy for patients with acromegaly or Cushing’s disease, potentially reflecting differences in practice among international centers, the clinical heterogeneity of patient populations, and ongoing uncertainties regarding the benefits of preoperative medical therapy.

“Single-center clinical experience suggests that preoperative medical therapy may be helpful in patients with Cushing’s disease and severe acute psychiatric illness or sepsis,” Fleseriu said. “Studies on acromegaly have very discordant results.

“With this study — the largest international Delphi consensus on perioperative management of patients undergoing pituitary surgery — we identified key steps in protocols which are ready to be implemented in most centers, especially for preoperative evaluation, sodium abnormalities and glucocorticoids administration postop,” Fleseriu said. “We have also highlighted several areas where need for more research is needed to optimize patients’ outcomes.”
