Research Study: An Open Label Study to Assess the Safety and Efficacy of COR-003 (2S, 4R-ketoconazole) in the Treatment of Endogenous Cushing’s Syndrome

Posted on November 14, 2014 by MaryO

Objectives:         

The purpose of this study is to test the effects of different doses of COR-003 on people with Cushing’s syndrome (CS) primarily by measuring the cortisol levels in urine and secondarily by measuring other health parameters such as blood pressure, weight, and liver function. This study is also being conducted to see if there is any harm caused when using COR-003.

This study is an open label study. That means both the health providers and the participants in the study are aware of the drug or treatment being given.

Eligibility:

Adult Subjects (18 years or older) with elevated levels of cortisol due to endogenous CS.

Confirmed diagnosis of persistent or recurrent CS (with or without therapy) or newly diagnosed disease, if subjects are not candidates for surgery. CS will be defined according to the criteria in the guidelines for diagnosis of CS (Nieman 2008).

Women who are pregnant or lactating are not eligible for this study.

Individuals with other health conditions or diagnoses may not be eligible for this study.

These and other eligibility criteria are best reviewed with a doctor who is participating in the study. You can also get more detailed eligibility information about the study by clicking here to visit http://www.clinicaltrials.gov.

Study Design:

  • The study will begin with a screening period to make sure subjects are eligible to participate in the study.
  • After the screening period, subjects who are eligible for participation will each be given several different doses of COR-003, to be taken orally in tablet form.
  • After an individualized dose has been selected, participants will take COR-003 for six months.
  • Finally, participants will continue in the study for an additional six months at doses to be determined by the study doctor.

 

Throughout the study, participants will meet regularly with a study doctor and will take part in a variety of medical tests to make sure they are doing well and to see if COR-003 is working.

Participants in the study should be sure they have the time to participate. Participants will generally be followed for over a year:

Study Locations

The study is currently taking place in several places around the world (United States, Belgium, France, Israel, Netherlands, Spain, and Sweden).

Rare neuroendocrine tumours may be misdiagnosed as Cushing’s disease

Posted on October 31, 2014 by MaryO

By Eleanor McDermid, Senior medwireNews Reporter

Ectopic tumours secreting corticotropin-releasing hormone (CRH) and adrenocorticotropic hormone (ACTH) are very rare in children and can result in a misdiagnosis of Cushing’s disease (CD), say researchers.

Three of the patients in the reported case series had pituitary hyperplasia and underwent transsphenoidal surgery for apparent CD before the tumour that was actually causing their symptoms was located. The hyperplasia was probably caused by release of CRH from the ectopic tumour, which stimulated the pituitary gland, giving the impression of an ACTH-secreting pituitary adenoma, explain Maya Lodish (National Institutes of Health, Bethesda, Maryland, USA) and study co-authors.

These three patients were part of a series of seven, which Lodish et al describe as “a relatively large number of patients, considering the infrequency of this disease.”

The patients were aged between 1.8 and 21.3 years. Three had neuroendocrine tumours located in the pancreas ranging in size from 1.4 to 7.0 cm, two had thymic carcinoids ranging from 6.0 mm to 11.5 cm, one patient had a 12.0 cm tumour in the liver and one had a 1.3 cm bronchogenic carcinoid tumour of the right pulmonary lobe.

Four of the patients had metastatic disease and, during up to 57 months of follow-up, three died of metastatic disease or associated complications and two patients had recurrent disease.

“Our series demonstrates that these are aggressive tumors with a high mortality rate,” write the researchers in the Journal of Clinical Endocrinology & Metabolism. “It is important to follow the appropriate work up, regarding both biochemical and imaging tests, which can lead to the correct diagnosis and to the most beneficial therapeutic approach.”

The team found the CRH stimulation test to be helpful, noting, for example, that none of the patients had a rise in cortisol that was consistent with CD, with all patients showing smaller responses ranging from 2% to 15%. Likewise, just one patient had an ACTH rise higher than 35% on CRH administration, and four patients had a “flat” response, which has previously been associated with ectopic neuroendocrine tumours.

Of note, six patients had normal or high plasma CRH levels, despite all having high cortisol levels, which would be expected to result in undetectable plasma CRH due to negative feedback, implying another source of CRH production. Five patients had blunted diurnal variation of both cortisol and ACTH levels consistent with Cushing’s syndrome.

The patients also underwent a variety of imaging procedures to identify the source of ACTH/CRH production, some of which, such as octreotide scans, are specialist and not available in most hospitals, the researchers note, potentially contributing to inappropriate diagnosis and management.

EU Looks to Okay Ketoconazole for Use in Cushing’s Syndrome

Posted on September 27, 2014 by MaryO

The Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended granting a marketing authorization for ketoconazole (Ketoconazole HRA; Laboratoire HRA Pharma) for the treatment of Cushing’s syndrome, a rare hormonal disorder sometimes called hypercortisolism.

Cushing’s syndrome is characterized by an excess of the hormone cortisol in the blood, which may be caused by a tumor. Treatment options currently available in the European Union include surgery to remove the tumor responsible for the high cortisol levels and radiotherapy, as well as several medicines that reduce the production of cortisol.

But pharmacological options remain very limited, and there is an unmet medical need for additional treatments, especially when surgery fails or for patients who cannot undergo surgery or take other medications. For this reason, the EMA’s CHMP evaluated the medicine under expedited review.

The opinion adopted by the CHMP at its September 2014 meeting is an intermediary step on Ketoconazole HRA’s path to patient access.

The CHMP opinion will now be sent to the European Commission for the adoption of a decision on an EU-wide marketing authorization. Once a marketing authorization has been granted, decisions about price and reimbursement will then take place at the level of each member state considering the potential role/use of this medicine in the context of the national health system of that country.

The recommendation is that Ketoconazole HRA is to be prescribed only by physicians specialized in treating Cushing’s syndrome, as the dosing needs to be individualized for each patient.

This is because oral ketoconazole was previously suspended in the European Union for the indication it was first approved for, fungal infections, due to risk for liver injury. The US Food and Drug Administration (FDA) also decreed, at the same time, that doctors should no longer prescribe ketoconazole tablets as a first-line therapy for any fungal infection, for the same reason.

Information will be sent to healthcare professionals to allow them to advise patients and prescribe the medicine safely and effectively.

A Medicine Used Off-Label for More than 30 Years

Doctors have used ketoconazole to treat Cushing’s syndrome for more than 30 years, although it has never been authorized for this indication in the European Union. The drug is also frequently used off-label in the United States and elsewhere for this purpose.

The CHMP’s recommendation builds on information from published literature and documented off-label use in clinical practice.

At the time of the suspension of ketoconazole for fungal infections, healthcare professionals and patients were concerned that ketoconazole would no longer be available for patients with Cushing’s syndrome.

The CHMP therefore reviewed Ketoconazole HRA through accelerated assessment to facilitate patients’ access to a fully authorized medicine as soon as possible with evidence-based information for patients and doctors.

When assessing Ketoconazole HRA for the treatment of Cushing’s syndrome, the CHMP considered that “in this rare and potentially life-threatening condition, the medicine’s benefits are greater than its risks, which can be manageable in clinical practice by specific measures mitigating the risk of liver toxicity, including close monitoring of the patients’ liver function.”

In 2012, it was estimated that the disease affected approximately 46,000 people in the European Union. Cushing’s syndrome is a long-lasting condition that can be life-threatening because of its complications, including diabetes, high blood pressure, and depression.

Cushing’s Awareness Challenge: Day 12

Posted on April 12, 2014 by MaryO

robin-head

 

Mail!  I get all kinds of email asking questions about a variety of Cushing’s issues.  I’m not a doctor and I don’t play one on TV.  I don’t even play one on the internet.  People are desperate for answers, though, so the questions keep coming and I try to answer the best I can.

Here’s a recent question and answer.  Note that you have to be logged into the message boards to view the links in this post.

 

Question: My daughter was diagnosed w/ cushings in 2001 at the age of 20 & had the pituitary surgery.

In late 2013 she was diagnosed with a recurrence. I’ve read that that usually happens within 5 years, not a dozen years.

Regardless, there is a new research program but she was told she doesn’t qualify for it. The other medications offered are either exhorbitant ($100-200,000/year), another causes liver damage, another causes uterine problems. A 2nd surgery is not recommended according to  the surgeon (because there would be only a 50% rate of success due to the scar tissue from the original surgery), and radiation is being vetoed as well, being recommended ONLY as a very last possible resort.

Are there other parents who chat & share experience here? Will I find help as a parent here with my frustration over this disease? Are there other patients who communicate here that are from Michigan?  Are there other patients here who are suffering from the recurrence? Don’t get me wrong, I’m happy to find on several sites online today that there are so many success stories; I would just like to know what other options there are that perhaps our Dr. is missing.  Thanks.

My response:

S, since you have a Board Name, I assume that you are a member of the message boards.

There are areas specifically for recurrence – http://cushings.invisionzone.com/index.php?/forum/35-recurrences/

People in Michigan: http://cushings.invisionzone.com/index.php?/topic/13696-michigan/

Parents of patients: http://cushings.invisionzone.com/index.php?/forum/31-parents-spouses-children-and-friends-of-patients/

The more you read, the more you will learn.  Many patients with a recurrence  have a second pituitary surgery.  She might need to get another opinion from another surgeon.

Another option is a BLA – or have her adrenal glands out.  That can cause other issues, though.

The 2 drugs you  mentioned are Signifor and Korlym.  Although both are expensive, each has a patient assistance plan which lowers the cost dramatically.  Doses can vary dramatically so that they don’t necessarily cause liver or uterine issues.

Ketoconazole is another drug that’s sometimes used.

I did a search on the boards and there are 69 topics for Mifepristone (generic Korlym), 51 topics discussing the brand name Korlym, 40 for pasireotide (generic Signifor), 13 for the brand name Signifor, and 69 for keto (the common abbreviation on the boards for ketoconazole)

Here’s a personal experience from a woman on Korlym who likes it: http://cushings.invisionzone.com/index.php?/topic/53342-i-like-korlym/?hl=korlym

So – the information is out there.

I know it’s hard to process all this and make decisions.

I know it’s hard to process all this and make decisions. I had my one pituitary surgery in 1987, before the Internet was available so I had to really research all this in medical texts.

At that time, there weren’t any drug options. Just surgery and radiation. I decided off the bat if I should have a recurrence, I would not do radiation. I’d go for another pituitary surgery first, then a BLA if needed.

But that was then and this is now.  There is way more information which is much easier to find.  There are better surgical options and even some more medical ones.

Good luck!

FDA Puts Strict Limits on Oral Ketoconazole Use

Posted on August 3, 2013 by MaryO

By John Gever, Deputy Managing Editor, MedPage Today

SILVER SPRING, Md. — Oral ketoconazole (Nizoral) should never be used as first-line therapy for any type of fungal infection because of the risk of liver toxicity and interactions with other drugs, the FDA said Friday.

The agency ordered a series of label changes and a new medication guide for patients that emphasize the risks, which also include adrenal insufficiency. It noted that the restrictions apply only to the oral formulation, not topical versions.

Late Thursday, the chief advisory body for the FDA’s European counterpart went further. The EU’s Committee on Medicinal Products for Human Use (CHMP) recommended that member nations pull oral ketoconazole from their markets entirely.

Both the FDA and the CHMP cited studies indicating high risks of severe, acute liver injury in patients taking the drug. Studies using the FDA’s adverse event reporting system and a similar database in the U.K. indicated that liver toxicity was more common with oral ketoconazole than with other anti-fungals in the azole class.

The FDA also said that oral ketoconazole “is one of the most potent inhibitors” of the CYP3A4 enzyme. This effect can lead to sometimes life-threatening interactions with other drugs metabolized by CYP3A4, and also to adrenal insufficiency, since the enzyme also catalyzes release of adrenal steroid hormones.

“This accounts for clinically important endocrinologic abnormalities observed in some patients (particularly when the drug is administered at high dosages), including gynecomastia in men and menstrual irregularities in women,” the FDA said.

The only indication for oral ketoconazole still supported by the FDA is for use in life-threatening mycoses in patients who cannot tolerate other anti-fungal medications or when such medications are unavailable.

In such instances, the FDA said, physicians should assess liver function before starting the drug. It is contraindicated in patients with pre-existing liver disease, and patients should be instructed not to drink alcohol or use other potentially hepatotoxic drugs.

Adrenal function should also be monitored in patients using the drug.

The CHMP also indicated the topical formulations of ketoconazole should stay on the market, but it found no basis for keeping the oral form available for any purpose.

“Taking into account the increased rate of liver injury and the availability of alternative anti-fungal treatments, the CHMP concluded that the benefits did not outweigh the risks,” the panel indicated in a statement.

It recommended that physicians stop prescribing oral ketoconazole and that they should review alternatives in patients currently receiving the drug. The committee also said that patients now taking oral ketoconazole “make a non-urgent appointment” with their physicians to discuss their treatment.
