Preclinical Data for ALD1613 at ENDO 2016

Alder BioPharmaceuticals, Inc. (“Alder”) (NASDAQ:ALDR), today announced that preclinical data on ALD1613, its anti-adrenocorticotropic hormone (ACTH) antibody for the treatment of congenital adrenal hyperplasia (CAH) and Cushing’s disease, were presented today by Andrew L. Feldhaus, Ph.D., in a poster presentation at ENDO 2016, the Endocrine Society’s 98th Annual Meeting in Boston, Mass. The presentation entitled “A Novel Anti-ACTH Antibody (ALD1613) Neutralizes ACTH Activity and Reduces Glucocorticoids in Rats and Nonhuman Primates” was presented as a late-breaking abstract.

Key Points:

  • In vitro, ALD1613 inhibits ACTH-induced cortisol secretion in a mouse adrenal cell line.
  • ALD1613 administration in rats with artificially elevated ACTH and corticosterone levels resulted in a rapid and durable reduction of plasma corticosterone levels.
  • In non-human primates, ALD1613 demonstrated stable and durable reductions in plasma cortisol levels by >50%.

Quote:

Randall C. Schatzman, Ph.D., President and Chief Executive Officer of Alder, said, “Existing therapeutic options for patients with congenital adrenal hyperplasia and Cushing’s disease comprise treatments that provide limited disease control and involve significant side effects. We believe these limitations indicate a clear need for new therapies such as ALD1613, which targets ACTH to diminish the overproduction of cortisol. The data presented today demonstrate the capacity of ALD1613 to reduce corticosteroid levels in preclinical settings. We intend to use these studies as part of an IND filing that we plan to submit to the FDA in the second half of 2016.”

Young people with Cushing syndrome may be at higher risk for suicide, depression

Children with Cushing syndrome may be at higher risk for suicide as well as for depression, anxiety and other mental health conditions long after their disease has been successfully treated, according to a study by researchers at the National Institutes of Health.

Cushing syndrome results from high levels of the hormone cortisol. Long-term complications of the syndrome include obesity, diabetes, bone fractures, high blood pressure, kidney stones and serious infections. Cushing’s syndrome may be caused by tumors of the adrenal glands or other parts of the body that produce excess cortisol. It also may be caused by a pituitary tumor that stimulates the adrenal glands to produce high cortisol levels. Treatment usually involves stopping excess cortisol production by removing the tumor.

“Our results indicate that physicians who care for young people with Cushing syndrome should screen their patients for depression-related mental illness after the underlying disease has been successfully treated,” said the study’s senior author, Constantine Stratakis, D(med)Sci, director of the Division of Intramural Research at NIH’s Eunice Kennedy Shriver National Institute of Child Health and Human Development. “Patients may not tell their doctors that they’re feeling depressed, so it’s a good idea for physicians to screen their patients proactively for depression and related conditions.”

Cushing syndrome may affect both adults and children. A recent study estimated that in the United States, there are 8 cases of Cushing syndrome per 1 million people per year.

The researchers published their findings in the journal Pediatrics. They reviewed the case histories of all children and youth treated for Cushing syndrome at NIH from 2003 to 2014, a total of 149 patients. The researchers found that, months after treatment, 9 children (roughly 6 percent) had thoughts of suicide and experienced outbursts of anger and rage, depression, irritability and anxiety. Of these, 7 experienced symptoms within 7 months of their treatment.

Two others began experiencing symptoms at least 48 months after treatment.

The authors noted that children with Cushing syndrome often develop compulsive behaviors and tend to become over-achievers in school. After treatment, however, they then become depressed and anxious. This is in direct contrast to adults with Cushing syndrome, who tend to become depressed and anxious before treatment and gradually overcome these symptoms after treatment.

The authors stated that health care providers might try to prepare children with Cushing syndrome before they undergo treatment, letting them know that their mood may change after surgery and may not improve for months or years. Similarly, providers should consider screening their patients periodically for suicide risk in the years following their treatment.

If you’re not familiar with clinical trials, here are some FAQs:

What are clinical trials?

Clinical trials are research studies to determine whether investigational drugs or treatments are safe and effective for humans. All new investigational medications and devices must undergo several clinical trials, often involving thousands of people.

Why participate in a clinical trial?

You will have access to investigational treatments that would be available to the general public only upon approval. You will also receive study-related medical care and attention from clinical trial staff at research facilities. Clinical trials offer hope for many people and an opportunity to help researchers find better treatments for others in the future.

Abstract

PURPOSE:
In a 10-week proof-of-concept study (LINC 1), the potent oral 11β-hydroxylase inhibitor osilodrostat (LCI699) normalized urinary free cortisol (UFC) in 11/12 patients with Cushing’s disease. The current 22-week study (LINC 2; NCT01331239) further evaluated osilodrostat in patients with Cushing’s disease.

METHODS:
Phase II, open-label, prospective study of two patient cohorts. Follow-up cohort: 4/12 patients previously enrolled in LINC 1, offered re-enrollment if baseline mean UFC was above ULN. Expansion cohort: 15 newly enrolled patients with baseline UFC > 1.5 × ULN. In the follow-up cohort, patients initiated osilodrostat twice daily at the penultimate efficacious/tolerable dose in LINC 1; dose was adjusted as needed. In the expansion cohort, osilodrostat was initiated at 4 mg/day (10 mg/day if baseline UFC > 3 × ULN), with dose escalated every 2 weeks to 10, 20, 40, and 60 mg/day until UFC ≤ ULN. Main efficacy endpoint was the proportion of responders (UFC ≤ ULN or ≥50 % decrease from baseline) at weeks 10 and 22.

RESULTS:
Overall response rate was 89.5 % (n/N = 17/19) at 10 weeks and 78.9 % (n/N = 15/19) at 22 weeks; at week 22, all responding patients had UFC ≤ ULN. The most common AEs observed during osilodrostat treatment were nausea, diarrhea, asthenia, and adrenal insufficiency (n = 6 for each). New or worsening hirsutism (n = 2) and/or acne (n = 3) were reported among four female patients, all of whom had increased testosterone levels.

CONCLUSIONS:
Osilodrostat treatment reduced UFC in all patients; 78.9 % (n/N = 15/19) had normal UFC at week 22. Treatment with osilodrostat was generally well tolerated.

Abstract

Pituicytoma is a tumor extremely rare in childhood, with only 4 cases reported in literature. It is thought to arise from the specialized glial elements called “pituicytes.” The association of pituicytoma and Cushing’s disease (CD) has been described only once so far, in an adult patient.

A 7-year-old girl was referred for clinical signs of hypercortisolism, and a diagnosis of CD was made. MRI revealed 2 pathologic areas in the pituitary gland. The patient underwent surgery, with microscopic transsphenoidal approach, and a well-circumscribed area of pathologic tissue was identified and removed. Surprisingly, histologic and immunohistochemical study provided unequivocal evidence of pituicytoma. No pituitary adenoma could be identified.

For persistent hypercortisolism, the patient necessitated transsphenoidal endoscopic reintervention and 2 other lesions were removed. By immunohistological examination, these lesions were confirmed to be corticotropin-secreting adenoma. Unfortunately, there was no postoperative decrease in corticotropin and cortisol levels, and the patient underwent bilateral laparoscopic adrenalectomy.

Considering that we report a second case of association of pituicytoma and corticotropin-secreting adenoma, that CD is infrequent, and pituicytoma is extremely rare in childhood, the coexistence of these 2 tumors should not be considered a mere coincidence. To date, there is no conclusive evidence about the origin of these different subtypes of pituitary tumors. This case supports the hypothesis that these tumors share a common progenitor cell, which could be the folliculostellate cell.
