A Single-Center 10-Year Experience with Pasireotide in Cushing’s Disease: Patients’ Characteristics and Outcome

Posted on April 30, 2016 by MaryO

Pasireotide is the first pituitary-directed drug approved for treating patients with Cushing’s disease (CD). Our 10-year experience with pasireotide in CD is reported here.

Twenty patients with de novo, persistent, or recurrent CD after pituitary surgery were treated with pasireotide from December 2003 to December 2014. Twelve patients were treated with pasireotide in randomized trials and 8 patients with pasireotide sc (Signifor®; Novartis AG, Basel, Switzerland) in clinical practice. The mean treatment duration was 20.5 months (median 9 months; range, 3-72 months).

Urinary free cortisol (UFC) levels mean percentage change (± SD) at last follow-up was-40.4% (± 35.1; range, 2-92%; median reduction 33.3%) with a normalization rate of 50% (10/20). Ten patients achieved sustained normalized late night salivary cortisol (LNSC) levels during treatment. LNSC normalization was associated with UFC normalization in 7/10 patients. Serum cortisol and plasma ACTH significantly decreased from baseline to last follow-up. Body weight decrease and blood pressure improvement during pasireotide treatment were independent from UFC response. Glucose profile worsening was observed in all patients except one. The frequency of diabetes mellitus increased from 40% (8/20) at baseline to 85% (17/20) at last follow-up requiring initiation of medical treatment only in 44% of patients.

Pasireotide treatment was associated with sustained biochemical and clinical benefit in about 60% of CD patients. Glucose profile alteration is a frequent complication of pasireotide treatment; however, it seems to be easy to manage with diet and lifestyle intervention in almost half of the patients.

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.

Unilateral andrenalectomy may be valid first-line treatment for Cushing’s syndrome

Posted on November 1, 2015 by MaryO

Debillon E, et al. J Clin Endocrinol Metab. 2015;doi:10.1210/jc.2015-2662.

In patients with evident Cushing’s syndrome related to primary bilateral macronodular adrenal hyperplasia, unilateral adrenalectomy of the large gland appears to be a suitable alternative to bilateral adrenalectomy as a first-line treatment, according to recent findings.

Unilateral adrenalectomy yielded normalized urinary free cortisol and improved Cushing’s syndrome, according to the researchers.

Olivier Chabre , MD, PhD, of the Service d’Endocrinologie-Diabétologie-Nutrition in France, and colleagues evaluated all patients (n = 15) with overt Cushing’s syndrome related to primary bilateral macronodular adrenal hyperplasia who underwent unilateral laparoscopic adrenalectomy of the larger gland between 2001 and 2015. Patients were seen for clinical and biological follow-up assessments at 1, 3 and 6 months postoperatively, 5 years after surgery and at the time of the last available urinary free cortisol measurement.

The study’s primary outcome measures were pre- and postoperative levels of urinary free cortisol, plasma cortisol, adrenocorticotropic hormone (ACTH), BMI, blood pressure, plasma glucose and lipids and measurements of these values on follow-up assessments. Patients were followed for a median of 60 months.

The researchers found that in early postoperative measurements, all 15 patients who underwent unilateral adrenalectomy achieved normal or low urinary free cortisol. Between 7 days and 1 month, there was a decrease in median urinary free cortisol from 2.19 times the upper limit of normal (ULN) at baseline to 0.27 ULN (P = .001). At 1 month, only one patient had elevated urinary free cortisol, and this patient went into remission by month 3 and continued to be in remission after 12 years of follow-up.

Forty percent of the patients developed adrenal insufficiency after unilateral adrenalectomy and latent adrenal insufficiency could not be excluded in two of the other patients. No predictors of postoperative adrenal insufficiency were identified.

Six of the patients had diabetes before unilateral adrenalectomy surgery; four of those were treated with antidiabetes drugs. At 12 months, only two of these patients had a continued need for antidiabetes drugs and had reductions in HbA1c despite decreases in their treatment. Recurrence occurred in two patients, demonstrating urinary free cortisol above the ULN at 7 years postoperatively and 8 years postoperatively. Both cases required treatment with mitotane, and in one of the patients, adrenalectomy of the second gland was required 9 years after the initial adrenalectomy.

According to the researchers, postoperative management and vigilant follow-up is needed in order to monitor patients for the risk for adrenal insufficiency.

“Further prospective studies are needed to better evaluate the long-term benefits of [unilateral adrenalectomy], which has one major benefit over [bilateral adrenalectomy]: if needed, [unilateral adrenalectomy] can be transformed in [bilateral adrenalectomy], while the opposite is obviously not true,” the researchers wrote. “One could propose that in further prospective studies [bilateral adrenalectomy] could be performed only if [unilateral adrenalectomy] fails to normalize [urinary free cortisol] at 1 month postoperatively.” – by Jennifer Byrne

Disclosure: The researchers report no relevant financial disclosures.

Abstract

Endogenous pathologic hypercortisolism, or Cushing’s syndrome, is associated with poor quality of life, morbidity and increased mortality. Early diagnosis may mitigate against this natural history of the disorder.

The clinical presentation of Cushing’s syndrome varies, in part related to the extent and duration of cortisol excess. When hypercortisolism is severe, its signs and symptoms are unmistakable. However, most of the signs and symptoms of Cushing’s syndrome are common in the general population (e.g. hypertension and weight gain) and not all are present in every patient.

In addition to classical features of glucocorticoid excess, such as proximal muscle weakness and wide purple striae, patients may present with the associated co-morbidities that are caused by hypercortisolism. These include cardiovascular disease, thromboembolic disease, psychiatric and cognitive deficits, and infections. As a result, internists and generalists must consider Cushing’s syndrome as a cause, and endocrinologists should search for and treat these co-morbidities.

Recommended tests to screen for Cushing’s syndrome include 1 mg dexamethasone suppression, urine free cortisol and late night salivary cortisol. These may be slightly elevated in patients with physiologic hypercortisolism, which should be excluded, along with exogenous glucocorticoid use. Each screening test has caveats and the choice of tests should be individualized based on each patient’s characteristics and lifestyle.

The objective of this review was to update the readership on the clinical and biochemical features of Cushing’s syndrome that are useful when evaluating patients for this diagnosis.

~~~

Well it has taken me a year to write this bio…and just to give some hope to those of you just going thru this process…I have to say that after surgery I have not felt better! I am back to who i always knew I was….the depression and anxiety is gone and I am living life like a 24 year old should!

I guess it all started when i was sixteen (hindsight is 20-20 i guess). My periods stopped i was tired all the time and the depression started. We all kind of just chalked it up to being sixteen. But my mom insisted something was not right. we talked with my gyno…who said nothing was wrong, I had a fungus on my head (my hair was getting really thin) and sometimes girls who had normal periods (in my case three years of normal periods) just go awry.

My mom wasnt hearing that and demanded a script for an endo. I went….he did blood work…and metioned cushings. But nothing came back definitive…so they put me on birthcontol and gave me some hormones and the chushings was never mentioned again because that all seemed to work.

As time went on my depression got worse, the shape of my body started to change-my face and stomach was the most noticeable- and my energy level kept going down. I kept going back to the doctors asking to be tested for mono..or something. I went to a psycologist….but i knew there was no reason for my depression. Two of them told me “i had very good insight” and that I didnt need them. I started getting more anxiety..especially about going out socially.

High school ended and my typical optimistic personality started to decline. I put on a good act to my friends but my family was seeing me break down all the time. I went away for college (all the while gaining weight). My sophmore year I had a break down..I called my family crying that i needed help. I couldnt beat my depression. I didnt drink in college because i knew that would mean instant weight gain, i barely went out…i exercised everyday..hard….i joined weight watchers…i stuck with it. I was at 103 lbs….that crept up to 110…that crept up to 117…each time my weight goal would be “ohh if i could just get back to 108..112…115” with each weight gain my original weight goal would get higher and higher.

Internally i felt like I was constantly under a black cloud..i knew there was no reason why i shoudl feel this way..i was doing great in school, i had a supportive family, an amazing boyfriend and great friends…why was i depressed? I was becoming emotionally draining to the people closest to me…I would go home a lot on the weekends…i was diagnosed with PMDS….like severe PMS..and was given an antidepresant…i hated it it made me feel like a zombie…i stopped taking it and just made it apoint to work on fighting the depression….and the weight gain.

When i was done college i was about 120 lbs. My face was getting rounder and rounder..i was noticing more hair on my face and arms…and a hump between my shoulder blades and the bottom of my neck. My mom saw a tv show about Polycystic ovarian syndrome and felt that maybe that was what was going on with me…i went to my PCP with this and she said it was possible and that i should to talk to my gyno….I am 4’8 and at the time weighing close to 125..i talked to my gyno and she said I was not heavy..that i was just “itailan” ..i told her my periods were getting abnormal again even w/the birthcontrol and that i was so tired all the time and my arms and legs ached. I also told her that i was bruising very easily…and that the weight gain would not stop despite my exercising and following the atikins diet very strickly for over 6 weeks. My boyfriend and I decided to try the diet together..he lost 35 llbs in 6 weeks..i lost NOTHING! I went back to my PCP who ordered an ultra sound of my ovaries…..NOTHING.(i kept thinking i was going crazy and that it was all in my head)….she also decided to do some blood work…and as i was walking out the door she said..”you know what..i am going to give you this 24hr urine test too. Just so that we cover everything”. I just kept thinking please let something come back ….please dont let this be all my fault…please dont let this be all in my head…..please dont let me be crazy. When i got the test results back it turned out that the 24hr urine test was the one test i needed to get on the right track to finding what was wrong. My cortisol level was 3x’s the normal.

I went to an endo…by the time i got to the endocronoligist i was up to 130…i could not work a full day without needing a full day of sleep and my body was aching beyond description. I was crying all the time…in my room…and was becoming more and more of a recluse…i would only hang out with my boyfriend in our houses. I looked my symptoms up on the internet and saw cushings…that was it! I went to the endo and told him..i think it is cushings….he said he had only saw it one other time and that he wanted to do more tests. I got CAT scans, x-rays, MRI’s….my adrenals my pituitary my lungs….he did a CRH stimulation test which was getting blood work done every fifteen minutes for 90minutes….it took weeks to get that test scheduled..no one had ever heard of it and therefore did not know how to do it…..finally after 3 months of tests my dr. felt he had enough evidence to diagnos me with cushings disease (tumor on my pituitary) I was diagnosed in March of 2004. By this time i was about 137 lbs i had to work part time (i am an occupational therapist for children..i do home visits….i could not make it thru a whole day)

In April i had to change to office work…i could not lift the children and i could barely get up off the floor. I have to say i was one of the lucky people who worked for people who were very supportive and accomidating…my boss was very willing to work with me and willing to hold my job for me.

July 30th 2004 i finally had transphenodial surgery to remove my tumor (they went thru my lip and nose because they felt my nose was too small). It is now over 1 year later….i am down to 108 lbs, i have so much energy…no depression….and i dont mind looking at myself in the mirror…i am enjoying my friends and my boyfriend…(who stayed with me thru it all) And my family. I feel healthy mentally, emptionally, and physically. And i just got back into my size 2 jeans!!!

It was a crappy time…(as i am sure you all can atest to) but i learned a lot…..most importantly i was bombarded by good wishes and prayers….friends requested masses for me…a nun in brazil prayed for me…people who i never thought i touched their lives…took the time to wish me well…send an email..or call….I got to experience the wonderful loving nature of human beings and i was lucky to be supported by my family (my mom, dad, and two younger brothers) and my boyfriend throughout this entire tough journey.

This experience taught me to realize the strength i have as well as to appreciate the good and the bad in life. I was on hydrocortizone for about 8 months…i was lucky that my tumor was in its own little sack so my pituitary gland was not touched. In the end in took about 7 years to diagnose me..i think that if the dr. at 16 would have pursued the cushings idea nothing would have been found because it took so long for my symptoms to really peak…needless to say i love my PCP and my endo ..and that i changed gyno’s…

I just want to let anyone out there going thru this disease to know..you are not alone….and to take each day is stride…when you need help ask for it….and that this road can lead to a happy ending. God Bless!

ps- it is ok to feel bad about what you are going thru…it is a tough thing to endure…and when the docotors tell you there is noting wrong…..follow your gut…and you keep searching for the doctor that will listen… If there is anyone in the philadelphis of south jersey area who needs someone to talk to please feel free to email me…fapadula@hotmail.com…i will help you out the best i can!

Update November 6, 2011

Well- here is an update, after seven years of being Cushings free it has returned.

With in those seven years I married my college boyfriend and we now have a son- Nicholas who will be 2 in Decemeber. It has been a blessed and wonderful seven years. However right around when my son was turning 1 I started to notice symptoms again. Increase facial hair, the whole “roundness” of my body, buffalo hump. I decided I was going to work out hard, eat right, and see – I didnt just want to jump to any conclusions. I stuck to it- and nothing…..my hair started thinning again and the acne was coming back and then the missed periods…..so I went to my PCP- told them i needed the 24hr urine and wouldnt you know…..427 cortisol level (on that 0-50 scale)……here we go again.

So back to endo- now at Penn Pituitary Center…..it was another journey b/c the tumor wasnt definative on MRI, and it seems to be cycling…..but I was diagnosed with Cushings again- with the option of 2nd pit surgery or BLA…….after some months of trying to make a decision I went with the 50/50 chance of the second pituitary surgery on 10/26/2011.

It didnt work- my levels never came down in the hospital and I went home w/ out of range cortisol levels and no need for medication……BLURG……Sooooo on to the next step…..after I recover from this surgery I will most likely have the BLA- with the hopes of not having to deal with Cushings ever again. This time around has been a little more difficult just with being a mom and feeling sick- but I still continue to be amazingly blessed with a supportive family and husband and we are surrounded by love and support and for that I am beyond greatful.

I keep all of you in my prayers for relief and health- as I ( we all) know this no easy journey.

Many Blessings!

Fabiana

Update September 12, 2015

So to bring this up to date. My second pituitary surgery in 2011 was unsuccessful. January of 2012 I had both of my adrenal glands removed. Going to adrenal insufficiency was a very difficult transition for me. It took me nearly 2 years before I felt functional. As time went on I felt more human, but I haven’t felt healthy since that day. I can and do function, but at a lower expectation of what I used to be capable of….my “new normal”.

My husband and I decided to try for a second child…my pituitary was damaged from the second surgery and we needed fertility…after 8 months of fertility I got pregnant and we had our second son January of 2015.

In April of 2015 we discovered that my ACTH was increasing exponentially. MRI revealed a macroadenoma invading my cavernous sinus. The tumor is sitting on my carotid artery and milimeterrs away from my optic chasim. I was not a candidate for another surgery due to the tumors proximity to.both of those vital structures.

So September 1st of this year I started daily radiation treatments. I spent my 34th birthday getting my brain zapped. I am receiving proton beam therapy at the Hospital of the University of Pennsylvania. I am so lucky to live so close to an institute that has some of the rarest treatment options.

Again Cushing’s is disrupting our life, my husband goes with me every night to radiation while family takes turns watching the kids….I am now on my 18th year of fighting this disease. I never imagined it would get to this point.

But here we all are making the best of each day, fighting each day and trying to keep things as “normal” as possible. Blessings to all of you fighting this disease…my new go to saying is” ‘effing Cushing’s”! For you newbies…Fight, Advocate for yourselves, and find a doc who doesn’t dismiss you and hang on to them for dear life.
