Health Care Expenditure Burden High in Adrenal Insufficiency

Patients with adrenal insufficiency may accrue substantial health care costs and have more hospital stays and outpatient visits compared with healthy controls, according to findings published in the Journal of the Endocrine Society.

Candace Gunnarsson, PhD, vice president of health economics and outcomes research at CTI Clinical Trial and Consulting in Cincinnati, and colleagues evaluated data from a U.S.-based payer database on 10,383 patients with adrenal insufficiency to determine the estimated annual health care burden among them.

Participants were divided into groups based on their type of adrenal insufficiency: primary adrenal insufficiency (n = 1,014), adrenal insufficiency secondary to pituitary disease (n = 8,818) or congenital adrenal hyperplasia (n = 551). A group of matched controls was also evaluated for comparison.

Total annual health care expenditures were significantly higher in the primary adrenal insufficiency group ($18,624 vs. $4,320), adrenal insufficiency secondary to pituitary disease group ($32,218 vs. $6,956) and the congenital adrenal hyperplasia group ($7,677 vs. $4,203) compared with controls. The adrenal insufficiency secondary to pituitary disease group had the highest health care expenditure estimated with an incremental health care burden of $25,262, followed by the primary adrenal insufficiency group ($14,304) and the congenital adrenal hyperplasia group ($3,474).

Compared with controls, participants with adrenal insufficiency spent eight to 10 times more days in the hospital and had up to twice as many outpatient visits per year.

“When comparing [adrenal insufficiency] patients within each cohort based on their drug regimen, patients receiving prednisone therapy vs. hydrocortisone therapy had significantly higher total annual expenditures in the [primary adrenal insufficiency] and [congenital adrenal hyperplasia] and significantly lower total expenditures in the [pituitary disease] cohort,” the researchers wrote. “Patients taking only hydrocortisone and meeting the threshold of 50% adherence were found to have lower expenditures when medication adherence was 75% or higher.” – by Amber Cox

Abstract

: Adrenal diseases-including disorders such as Cushing’s syndrome, Addison’s disease, pheochromocytoma, primary hyperaldosteronism and congenital adrenal hyperplasia-are relatively rare in pregnancy, but a timely diagnosis and proper treatment are critical because these disorders can cause maternal and fetal morbidity and mortality.

Making the diagnosis of adrenal disorders in pregnancy is challenging as symptoms associated with pregnancy are also seen in adrenal diseases. In addition, pregnancy is marked by several endocrine changes, including activation of the renin-angiotensin-aldosterone system and the hypothalamic-pituitary-adrenal axis.

The aim of this article was to review the pathophysiology, clinical manifestation, diagnosis and management of various adrenal disorders during pregnancy.

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.

How does COVID-19 impact the adrenal gland?

This month marks a little over one year since the first surge of COVID-19 across the United States. April is also Adrenal Insufficiency Awareness month, a good time to review the data on how COVID-19 infection can impact the adrenal glands.

The adrenal glands make hormones to help regulate blood pressure and the ability to respond to stress. The hormones include steroids such as glucocorticoid (cortisol), mineralocorticoid (aldosterone), and forms of adrenaline known as catecholamines (norepinephrine, epinephrine, and dopamine). The activity of the adrenal gland is controlled through its relationship with the pituitary gland (the master regulator of hormones in the body).

Some common adrenal diseases include the following:

  • Addison’s Disease (where the body attacks the adrenal glands making them dysfunctional)
  • Hyperaldosteronism
  • Cushing’s Syndrome
  • Pheochromocytoma
  • Adrenal Nodules/Masses (termed incidentaloma)
  • Congenital adrenal hyperplasia

COVID-19 was found in the adrenal and pituitary glands of some patients who succumbed to the illness, suggesting that these organs might be among the targets for infection.  One of the first highly effective therapies for COVID-19 infection was the use of IV steroid (dexamethasone) supplementation in hospitalized patients in patients requiring oxygen.

A focused search of COVID-19-related health literature shows 85 peer-reviewed papers that have been published in medical literature specifically on the adrenal gland and COVID-19. This literature focuses on three phases of COVID infection that may impact the adrenal gland: the acute active infection phase, the immediate post-infection phase, and the long-term recovery phase.

Medical research has identified that during the acute active infection, the adrenal system is one of the most heavily affected organ systems in the body in patients who have COVID-19 infection requiring hospitalization. In these cases, supplementation with the steroid dexamethasone serves as one of the most powerful lifesaving treatments.

Concern has also been raised regarding the period of time just after the acute infection phase – particularly, the development of adrenal insufficiency following cases of COVID-19 hospitalizations. Additionally, some professional societies recommend that for patients who have adrenal insufficiency and are on adrenal replacement therapy, they be monitored closely post-COVID-19 vaccine for the development of stress-induced adrenal insufficiency.

In mild-to-moderate COVID-19 cases, there does not seem to be an effect on adrenaline-related hormones (norepinephrine, epinephrine, dopamine). However, in cases of severe COVID-19 infection triggering the development of shock, patients will need supplementation with an infusion of catecholamines and a hormone called vasopressin to maintain their blood pressure.

Finally, some studies have addressed the concern of adrenal insufficiency during the long-term recovery phase. Dr Sara Bedrose, adrenal endocrine specialist at  Baylor College of Medicine, indicates that studies which included adrenal function in COVID survivors showed a large percentage of patients with suboptimal cortisol secretion during what is called ACTH stimulation testing.

Results indicated that most of those cases had central adrenal insufficiency. It was concluded that adrenal insufficiency might be among the long-term consequences of COVID-19 and it seemed to be secondary to pituitary gland inflammation (called hypophysitis) or due to direct hypothalamic damage. Long-term follow-up of COVID 19 survivors will be necessary to exclude a gradual and late-onset adrenal insufficiency.

Some patients who have COVID-19 will experience prolonged symptoms. To understand what is happening to them, patients may question whether or not they have a phenomenon called adrenal fatigue. This is a natural question to ask, especially after having such a severe health condition. A tremendous amount of resources are being developed to investigate the source and treatment of the symptoms, and this work has only just begun.

However, adrenal fatigue is not a real medical diagnosis. It’s a term to describe a group of signs and symptoms that arise due to underactive adrenal glands. Current scientific data indicate that adrenal fatigue is not in and of itself a medical disease – although a variety of over-the-counter supplements and compounded medications may be advocated for in treatment by alternative medicine/naturopathic practitioners.

My takeaway is that we have learned a great deal about the effects COVID-19 infection has on the adrenal glands. Long-term COVID-19 remains an area to be explored –  especially in regards to how it may affect the adrenal glands.

Hydrocortisone in Granule Form Effectively Treats Childhood Adrenal Insufficiency

The treatment of adrenal insufficiency with hydrocortisone granules in children with congenital adrenal hyperplasia (CAH) was associated with an absence of adrenal crises and normal growth patterns over a 2-year period, according to study findings published in The Journal of Clinical Endocrinology and Metabolism.

The study included a total of 17 children with CAH and 1 child with hypopituitarism. All included participants were <6 years old who were receiving current adrenocortical replacement therapy, including hydrocortisone with or without fludrocortisone. Hydrocortisone medications used in this population were converted from pharmacy compounded capsules to hydrocortisone granules without changing the dose.

These study participants were followed by study investigators for 2 years. Glucocorticoid replacement therapy was given three times a day for a median treatment duration of 795 days. Treatment was adjusted by 3 monthly 17-hydroxyprogesterone (17-OHP) profiles in children with CAH.

There were a 150 follow-up visits throughout the study. At each visit, participants underwent assessments that measured hydrocortisone dose, height, weight, pubertal status, adverse events, and incidence of adrenal crisis.

A total of 40 follow-up visits had changes in hydrocortisone doses based on salivary measurements (n=32) and serum 17-OHP levels (n=8).

At time of study entry, the median daily doses of hydrocortisone were 11.9 mg/m2 for children between the ages of 2 to 8 years, 9.9 mg/m2 for children between 1 month and 2 years, and 12.0 mg/m2 for children <28 days of age. At the end of the study, the respective doses for the 3 age groups were 10.2, 9.8, and 8.6.

The investigators observed no trends in either accelerated growth or reduced growth; however, 1 patient with congenital renal hypoplasia and CAH did show reduced growth. While 193 treatment-emergent adverse events, including pyrexia, gastroenteritis, and viral upper respiratory tract infection, were reported in 14 patients, there were no observed adrenal crises.

Limitations of this study included the small sample size as well as the relatively high drop-out rate of the initial sample.

The researchers concluded that “hydrocortisone granules are an effective treatment for childhood adrenal insufficiency providing the ability to accurately prescribe pediatric appropriate doses.”
