From Weight Gain To Diabetes

Cushing’s syndrome happens when the body has too much cortisol, the stress hormone. It can cause weight gain, high blood pressure, and diabetes. So how to keep your health in check and what are the treatment options available? In an exclusive interview with Times Now, an Endocrinologist explains its symptoms, causes, and treatments.
We often blame stress for everything—from sleepless nights to stubborn weight gain. But did you know your body’s stress hormone, cortisol, could be at the root of more serious health issues like high blood pressure and diabetes? Yes, you read that right! But how? We got in touch with Dr Pranav A Ghody, Endocrinologist at Wockhardt Hospital, Mumbai Central, who explains how excessive cortisol levels can lead to a condition known as Cushing’s Syndrome.
What Exactly is Cortisol, and Why is it Important?
Hormones are the body’s chemical messengers, travelling through the bloodstream to regulate essential functions. Among them, cortisol, produced by the adrenal glands (tiny glands sitting above the kidneys), plays a crucial role in controlling blood pressure, blood sugar, energy metabolism, and inflammation. The pituitary gland, located at the base of the brain, regulates cortisol through another hormone called Adrenocorticotropic Hormone (ACTH).
Often referred to as the “stress hormone,” cortisol spikes when we’re under stress. However, when levels remain high for too long, it can lead to Cushing’s Syndrome, a disorder first identified in 1912 by Dr Harvey Cushing.

What Causes Cushing’s Syndrome?

Dr Ghody explains that Cushing’s Syndrome occurs when the body is exposed to excessive cortisol, which can happen in two ways:

1. Exogenous (External) Cushing’s Syndrome
This is the most common form and results from prolonged use of steroid medications (such as prednisone) to treat conditions like asthma, rheumatoid arthritis, and lupus, or to prevent transplant rejection. Since steroids mimic cortisol, long-term use can disrupt the body’s hormone balance.
2. Endogenous (Internal) Cushing’s Syndrome
This occurs when the body produces too much cortisol due to a tumour in the pituitary gland, adrenal glands, or other organs (lungs, pancreas, thymus). While rare—affecting about 10 to 15 people per million annually—it’s more common in women between 20 and 50 years old. When caused by a pituitary tumour, it’s specifically called Cushing’s Disease.

Symptoms: How To Recognize Signs Of Cushing’s Syndrome

Excess cortisol affects multiple organs, leading to a variety of symptoms. This includes:

– Weight gain around the belly (central obesity)
– Rounded, puffy face (moon face)
– Excess facial and body hair (hirsutism)
– Fat accumulation on the upper back (buffalo hump)
– Thin arms and legs
– Dark red-purple stretch marks on the chest and abdomen
– Extreme fatigue and muscle weakness
– Depression or anxiety
– Easily bruising with minimal trauma
– Irregular menstrual cycles in women
– Reduced fertility or low sex drive
– Difficulty sleeping
High blood pressure and newly diagnosed or worsening diabetes are also common red flags.

Why is Cushing’s Syndrome Often Misdiagnosed?

Dr Ghody explains that while severe cases of Cushing’s Syndrome are easier to identify, milder forms can often be missed or mistaken for conditions like obesity, diabetes, or polycystic ovary syndrome (PCOS).

Diagnosing Cushing’s Syndrome involves:
1. Measuring cortisol levels in the blood, urine, or saliva.
2. Identifying the source through ACTH hormone testing, MRI/CT scans, and advanced techniques like Inferior Petrosal Sinus Sampling (IPSS) or nuclear medicine scans
Treatment Options: How is Cushing’s Syndrome Managed?
Once diagnosed, the treatment depends on the cause:
– If due to steroid medication, the dosage is gradually reduced under medical supervision.
– If caused by a tumour, surgery is the primary treatment. Some patients, especially those with pituitary tumours, may require repeat surgery, gamma knife radiosurgery, or medications to control cortisol levels.

Can You Prevent Cushing’s Syndrome?

While complete prevention isn’t always possible, Dr Ghody shares some key strategies to reduce risk:

– Use steroids cautiously – If prescribed, take the lowest effective dose for the shortest time. Never stop abruptly without consulting a doctor.
– Genetic screening for people at risk – If you have a family history of pituitary or adrenal tumours, regular monitoring can help with early detection.
– Maintain a healthy lifestyle – A diet rich in fresh vegetables, and fruits, low sodium intake, adequate calcium, and vitamin D can help manage the metabolic effects of excess cortisol.
– Avoid alcohol and tobacco – These can further disrupt hormone balance and overall health.
“Cushing’s Syndrome can be life-threatening if left untreated, but early diagnosis and proper management can significantly improve quality of life. So if you experience unexplained weight gain, blood pressure spikes, or other symptoms, consult an endocrinologist to manage hormonal imbalances,” he said.

Sterotherapeutics begins Phase II trial for ST-002 targeting Cushing’s Syndrome

US-based clinical-stage company Sterotherapeutics has announced the commencement of a Phase II clinical trial for its drug candidate, ST-002, for treating Cushing’s Syndrome, a rare endocrine disorder.

The trial will assess the drug’s efficacy, tolerability, and safety in individuals with this condition. It is set to be conducted in several European clinical sites.

Sterotherapeutics CEO Manohar Katakam said: “After extensive preparations and based on a large body of scientific data, we are excited to convene this important Investigator Meeting as we progress to the next stage of our clinical development programme.

“This trial represents a significant step forward in our mission to develop transformative therapies for unmet medical needs. Collaboration with our expert investigators is essential to ensuring the highest standards of scientific rigour and patient safety.”

An orphan drug designation was granted by the US Food and Drug Administration (FDA) to the drug underscoring the requirement for new treatments alternatives for this rare condition.

Through this designation, Sterotherapeutics is eligible for various development incentives. These include assistance in the drug development process, certain FDA fee exemptions, post-approval marketing exclusivity of seven years, and tax credits for clinical expenses.

Characterised by longer exposure to high cortisol levels, Cushing’s Syndrome is stated to result in serious health complications like diabetes, osteoporosis, and hypertension.

Sterotherapeutics concentrates on the orphan diseases therapy development. The company stated that its leading programmes, ST-002 for Cushing’s Syndrome and ST-003 for primary sclerosing cholangitis, have shown promise in prior animal and human studies. ST-003 has also been granted an orphan drug designation by the US regulator.

Oncocytic Pituicytoma in a Patient with Cushing’s Disease

The final, formatted version of the article will be published soon.

1) Background: Posterior pituitary tumors (PPTs) are extremely rare, with fewer than 400 cases reported to date. In 2022, the WHO classified four types of tumors originating from the posterior pituitary: traditional pituicytoma, oncocytic pituicytoma, granular pituicytoma, and ependymal pituicytoma. To our knowledge, only one subject with coexistence of Cushing’s disease and oncocytic pituicytoma (spindle cell oncocytoma) has been reported, but the clinical features of this patient were not described in detail.

2) Case presentation: We presented a case of a patient with Cushing’s syndrome and a pituitary mass. Transsphenoidal surgery was performed, and pathologic examination revealed two distinct tumors: a corticotroph adenoma with a diameter of less than 2mm and a larger oncocytic pituicytoma. Post-surgery serum cortisol was 51 nmol/L, indicating complete remission. Corticotroph adenoma or corticotroph hyperplasia were identified after surgery in less than half of the subjects with Cushing’s disease and PPT. (3)

Conclusions: Our study indicates that Cushing’s disease in patients with PPT may be caused by the existence of collision lesions, with corticotroph adenoma or hyperplasia being difficult to detect due to their small dimensions.

Ectopic Adrenocorticotrophic Hormone Syndrome in a 10-Year-Old Girl With a Thymic Neuroendocrine Tumor

Abstract

Background

Thymic neuroendocrine tumor as a cause of Cushing syndrome is extremely rare in children.

Case presentation

We report a case of a 10-year-old girl who presented with typical symptoms and signs of hypercortisolemia, including bone fractures, growth retardation, and kidney stones. The patient was managed with oral ketoconazole, during which she experienced adrenal insufficiency, possibly due to either cyclic adrenocorticotropic hormone (ACTH) secretion or concurrent COVID-19 infection. The patient underwent a diagnostic work-up which indicated the possibility of an ACTH-secreting pituitary neuroendocrine tumor. However, after a transsphenoidal surgery, the diagnosis was not confirmed on histopathological examination. Subsequent bilateral inferior petrosal sinus sampling showed strong indications of the presence of ectopic ACTH syndrome. Detailed rereading of functional imaging studies, including 18F-FDG PET/MRI and 68Ga DOTATOC PET/CT, ultimately identified a small lesion in the thymus. The patient underwent videothoracoscopic thymectomy that confirmed a neuroendocrine tumor with ACTH positivity on histopathological examination.

Conclusion

This case presents some unique challenges related to the diagnosis, management, and treatment of thymic neuroendocrine tumor in a child. We can conclude that ketoconazole treatment was effective in managing hypercortisolemia in our patient. Further, a combination of functional imaging studies can be a useful tool in locating the source of ectopic ACTH secretion. Lastly, in cases of discrepancy in the results of stimulation tests, bilateral inferior petrosal sinus sampling is highly recommended to differentiate between Cushing disease and ectopic ACTH syndrome.

Peer Review reports

Background

In children above seven years of age, the majority of pediatric Cushing syndrome (CS) cases are caused by a pituitary neuroendocrine tumors (PitNET). However, a differential diagnosis of hypercortisolemia in children is often challenging concerning the interpretation of stimulation tests and the fact that up to 50% of PitNET may not be detected on magnetic resonance imaging (MRI) [1]. An ectopic adrenocorticotropic hormone (ACTH) syndrome (EAS) is extremely rare in children. Its diagnosis is often missed or confused with Cushing disease (CD) [2]. Most ACTH-secreting tumors originate from bronchial or thymic neuroendocrine tumors (NETs), or less commonly, from NETs in other locations. To diagnose EAS, specific functional imaging studies are often indicated to elucidate the source of ACTH production.

Pharmacotherapy may be used before surgery to control hypercortisolemia and its symptoms/signs, or in patients in whom the source of hypercortisolism has not been found (e.g., EAS), or surgery failed. Ketoconazole or metyrapone, as adrenal steroidogenesis blockers, were found to be very efficient, although they exhibit side effects [3].

Furthermore, cyclic secretion of ACTH followed by fluctuating plasma cortisol levels is extremely rare in children, including those with EAS [45]. Therefore, in cyclic EAS, the use of steroid inhibitors or acute illness or trauma can be associated with adrenal insufficiency, which can be life-threatening. Here we describe the clinical features, laboratory and radiological investigations, results, management, and clinical outcome of a 10-year-old girl with a thymic NET presenting with ACTH secretion.

Case presentation

A 10-year-old girl was acutely admitted to our university hospital for evaluation of facial edema and macroscopic hematuria in May 2021. A day before admission, she presented to the emergency room for dysuria, pollakiuria, nausea, and pain in her right lower back. Over the past year she had experienced excessive weight gain with increased appetite and growth retardation (Fig. 1). Her height over three years had shifted from the 34th to the 13th centile (Fig. 1). Her parents noticed facial changes, pubic hair development, increased irritability, and moodiness.

At admission, she was found to have a moon face with a plethora, few acne spots on forehead, as well as facial puffiness. In contrast to slim extremities, an abnormal fat accumulation was observed in the abdomen. Purple striae were present on abdomen and thighs. She did not present with any bruising, proximal myopathy, or edema. On physical examination, she was prepubertal, height was 135 cm (13th centile), and weight was 37 kg (69th centile) with a BMI of 20.4 kg/m2 (90th centile). She developed persistent hypertension. Her past medical history was uneventful except for two fractures of her upper left extremity after minimal trips one and three years ago, both treated with a caste. Apart from hypothyroidism on the maternal side, there was no history of endocrine abnormalities or tumors in the family.

In the emergency room, the patient was started on sulfonamide, pain medication, and intravenous (IV) fluids. Her hypertensive crises were treated orally with angiotensin-converting enzyme inhibitor or with a combination of adrenergic antagonists and serotonin agonists administered IV. Hypokalemia had initially been treated with IV infusion and then with oral potassium supplements. A low serum phosphate concentration required IV management. The initial investigation carried out in the emergency room found hematuria with trace proteinuria. Kidney ultrasound showed a 5 mm stone in her right ureter with a 20 mm hydronephrosis. She did not pass any kidney stones, however, fine white sand urine analysis reported 100% brushite stone.

Hypercortisolemia was confirmed by repeatedly increased 24-hour urinary free cortisol (UFC), (5011.9 nmol/day, normal range 79.0-590.0 nmol/day). Her midnight cortisol levels were elevated (961 nmol/l, normal range 68.2–537 nmol/l). There was no suppression of serum cortisol after 1 mg overnight dexamethasone suppression test (DST) or after low-dose DST (LDDST). An increased morning plasma ACTH (30.9 pmol/l, normal range 1.6–13.9 pmol/) suggested ACTH-dependent hypercortisolemia. There was no evidence of a PitNET on a 1T contrast-enhanced MRI. The high-dose DST (HDDST) did not induce cortisol suppression (cortisol 1112 nmol/l at 23:00, cortisol 1338 nmol/l at 8:00). Apart from the kidney stone, a contrast-enhanced computed tomography (CT) of her neck, chest, and abdomen/pelvis did not detect any lesion. Various tumor markers were negative and the concentration of chromogranin A was also normal.

A corticotropin-releasing hormone (CRH) stimulation test induced an increase in serum cortisol by 32% at 30 min and ACTH concentration by 67% at 15 min (Table 1). A 3T contrast-enhanced MRI scan of the brain identified a 3 × 2 mm lesion in the lateral right side of the pituitary gland (Fig. 2). An investigation of other pituitary hormones was unremarkable. Apart from low serum potassium (minimal level of 2.8 mmol/l; normal range 3.3–4.7 mmol/l) and phosphate (0.94 mmol/l; normal range 1.28–1.82 mmol/l) concentrations, electrolytes were normal. The bone mineral density assessed by whole dual-energy X-ray absorptiometry was normal.

The patient was presented at the multidisciplinary tumor board and it was decided that she undergoes transsphenoidal surgery for the pituitary lesion. No PitNET was detected on histopathological examination and no favorable biochemical changes were noted after surgery. After the patient recovered from surgery, subsequent bilateral inferior petrosal sinus sampling (BIPSS) confirmed EAS as the maximum ratio of central to peripheral ACTH concentrations was only 1.7. During the investigation for tumor localization, she was started on ketoconazole treatment (300 mg/day) to alleviate symptoms and signs of hypercortisolism. Treatment with ketoconazole had a beneficial effect on patient health (Fig. 1). There was a weight loss of 2 kg in a month, a disappearance of facial plethora, and a decrease in vigorous appetite. Her liver function tests remained within the normal range.

Table 1 Result of corticotropin-releasing hormone stimulation test

The 24-hour UFC excretion normalized three weeks after ketoconazole initiation. However, six weeks after continuing ketoconazole therapy (400 mg/day), the patient complained of nausea, vomiting, and diarrhea. She was found to have adrenal insufficiency with a low morning serum cortisol of 10.70 nmol/l (normal range 68.2–537 nmol/l) and salivary cortisol concentrations < 1.5 nmol/l (normal range 1.7–29 nmol/l). She was also found to be positive for COVID-19 infection. Ketoconazole treatment was stopped and our patient was educated to take stress steroids in case of persisting or worsening symptoms. Her clinical status gradually improved and steroids were not required.

Meanwhile, whole-body fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET)/MRI was performed with no obvious hypermetabolic lesion suspicious of a tumor. No obvious accumulation was detected on 68Ga-DOTATOC PET/CT images (Fig. 3). However, a subsequent careful and detailed re-review of the images detected a discrete lesion on 18F-FDG PET/MRI and 68Ga-DOTATOC PET/CT scans in the left anterior mediastinum, in the thymus (Fig. 4).

Three weeks after the episode of adrenal insufficiency and being off ketoconazole treatment, our patient´s pre-surgery laboratory tests showed slightly low morning cortisol 132 nmol/l with surprisingly normal ACTH 2.96 pmol/l (normal range 1.6–13.9 pmol/). Given the upcoming surgery, she was initiated on a maintenance dose of hydrocortisone (15 mg daily = 12.5 mg/m2/day). Further improvement of cushingoid characteristics (improvement of facial plethora and moon face, weight loss) was noticed. Our patient underwent videothoracoscopic surgery, and a hyperplastic thymus of 80 × 70 × 15 mm with a 4 mm nodule was successfully removed. Tumor immunohistochemistry was positive for ACTH, chromogranin A, CD56, and synaptophysin. Histopathological findings were consistent with a well-differentiated NET grade 1. A subsequent genetic screening did not detect any pathogenic variant in the MEN1 gene.

After surgery, hydrocortisone was switched to a stress dose and gradually decreased to a maintenance dose. Antihypertensive medication was stopped and further weight loss was observed after thymectomy. Within a few weeks after the thoracic surgery, the patient entered puberty, her mood improved significantly, and potassium supplements were stopped. Finally, hydrocortisone treatment was stopped ten months after thymectomy.

Discussion and conclusions

The case presented here demonstrates a particularly challenging work-up of the pediatric patient with the diagnosis of CS caused by EAS due to thymic NET. Differentiating CD and EAS can sometimes be difficult, including the use of various laboratory and stimulation tests and their interpretation, as well as proper, often challenging, reading of functional imaging modalities, especially if a discrete lesion is present at an unusual location [1]. When using established criteria for Cushing disease (for the CRH test an increase of cortisol and/or ACTH by ≥ 20% or ≥ 35%, respectively, and a ≥ 50% suppression of cortisol for the HDDST) our patient presented discordant results. The CRH stimulation test induced an increase in cortisol by 32% and ACTH by 67% and the 3T MRI pointed to the right-side pituitary lesion, both to yield false positive results. The HDDST, on the other hand, did not induce cortisol suppression and was against characteristic findings for CD. We did not proceed with desmopressin testing, which also induces an excess ACTH and cortisol response in CD patients and has rarely been used in pediatric patients, except in those with extremely difficult venous access [6]. Recently published articles investigated the reliability of CRH stimulation tests and HDDST and both concluded that the CRH test has greater specificity than HDDST [78]. Elenius et al. suggested optimal response criteria as a ≥ 40% increase of ACTH and/or cortisol (cortisol as the most specific measure of CD) during the CRH test and a ≥ 69% suppression of serum cortisol during HDDST [7]. Using these criteria, the CD would be excluded in our patient. To demonstrate that the proposed thresholds for the test interpretation widely differ, Detomas et al. proposed a ≥ 12% cortisol increase and ≥ 31% ACTH increase during the CRH test to confirm CD [8].

The fact that up to 50% of PitNET may not be detected on MRI [1] and that more than 20% of patients with EAS are reported to have pituitary incidentalomas [9] makes MRI somewhat unreliable in differentiating CD and EAS. However, finally, well-established and generally reliable BIPSS in our patient supported the diagnosis of EAS. Thus, BIPSS is considered a gold standard to differentiate between CD and EAS; however, it can still provide false negative results in cyclic CS if performed in the trough phase [10] or in vascular anomalies or false positive results as in a recent case of orbital EAS [11].

In children, the presence of thymus tissue may be misinterpreted as normal. Among other reports of thymic NET [12], Hanson et al. reported a case of a prepubertal boy in whom a small thymic NET was initially treated as normal thymus tissue on CT [13]. In our case, initially, the lesion was not detected on the 18F-FDG and 68Ga-DOTATOC PET scans. A small thymic NET was visible only after a detailed and careful re-reading of both PET scans. Although somatostatin receptor (SSR) PET imaging may be helpful in identifying ectopic CRH- or ACTH-producing tumors, there are still some limitations [13]. For example, in the study by Wannachalee et al., 68Ga-DOTATATE identified suspected primary lesions causing ECS in 65% of patients with previously occult tumors and was therefore concluded as a sensitive method for primary as well as metastatic tumors [14]. In our patient, the final correct diagnosis was based on the results of both PET scans. This is in full support of the article published by Liu et al. who concluded that 18F-FDG and SSR PET scans are complementary in determining the proper localization of ectopic ACTH production [15]. Additionally, it is worth noting that not all NETs stain positively for ACTH which may present a burden in its identification.

To control hypercortisolemia, both ketoconazole and metyrapone were considered in our patient. Due to the side effects of metyrapone on blood pressure, ketoconazole was started as a preferred option in our pediatric patient. A retrospective multicenter study concluded that ketoconazole treatment is effective with acceptable side effects, with no fatal hepatitis and adrenal insufficiency in 5.4% of patients [3]. During ketoconazole treatment, our patient developed adrenal insufficiency; however, it is impossible to conclude whether this was solely due to ketoconazole treatment or whether an ongoing COVID-19 infection contributed to the adrenal insufficiency or whether this was caused by a phase of lower or no ACTH secretion from the tumor often seen in patients with cyclic ACTH secretion. The patient’s cyclic ACTH secretion is highly probable since her morning cortisol was slightly lower and ACTH was normal, even after being off ketoconazole treatment for 3 weeks.

When retrospectively and carefully reviewing all approaches to the diagnostic and management care of our pediatric patient, it would be essential to proceed to BIPSS before any pituitary surgery, especially when obtaining discrepant results from stimulation tests, as well as detecting a discrete pituitary lesion ( 6 mm) as recommended by the current guidelines [16]. This was our first experience using ketoconazole in a young child, and although this treatment was associated with very good outcomes in treating hypercortisolemia, close monitoring, and family education on signs and symptoms of adrenal insufficiency are essential to recognizing adrenal insufficiency promptly in any patient with EAS, especially those presenting also with some other comorbidities or stress, here COVID-19 infection.

In conclusion, the pediatric patient here presenting with EAS caused by thymic NET needs very careful assessment including whether cyclic CS is present, the outline of a good management plan to use all tests appropriately and in the correct sequence, monitoring carefully for any signs or symptoms of adrenal insufficiency, and apply appropriate imaging studies, with experienced radiologists providing accurate readings. Furthermore, ketoconazole treatment was found to be effective in reducing the symptoms and signs of CS in this pediatric patient. Finally, due to the rarity of this disease and the challenging work-up, we suggest that a multidisciplinary team of experienced physicians in CS management is highly recommended.

Corcept’s relacorilant GRADIENT trial misses primary endpoint

Corcept Therapeutics has shared some results from its Phase III GRADIENT trial for relacorilant – its experimental treatment for Cushing’s syndrome caused by adrenal gland pathology.

The trial will be used alongside data from the earlier GRACE trial to support the company’s new drug application (NDA) submission this quarter. However, it missed its primary endpoint.

The complete results of the company’s GRADIENT trial will be presented at a medical conference next year, but current results – released on 30 October – demonstrate that there was no statistically significant difference in hypertension in relacorilant and placebo patients.

The randomised double-blind trial included 137 patients across sites in the US, Europe and Israel. Over 22 weeks, half of the patients received relacorilant while the other half received a placebo.

The trial’s primary endpoint was the improvement in systolic blood pressure (SBP) compared to placebo. Its secondary endpoints were concerned with hyperglycemia, weight and body composition.

Mean SBP saw a reduction of 6.6 mm Hg in relacorilant patients compared to baseline. This is in contrast to a reduction of 2.1 mm Hg in placebo patients. The difference between these results was not statistically significant.

However, Corcept’s GRADIENT trial did meet some secondary endpoints and was well-tolerated. Patients taking relacorilant exhibited clinically meaningful and statistically significant improvements in hypertension, hyperglycemia, weight and body composition compared to baseline. In contrast, placebo patients did not.

Cushing’s syndrome is caused by an excess of cortisol and primarily affects those using steroid medications, which contain a synthetic version of the hormone. The condition is characterised by an increase of fat (particularly on the neck and shoulders), a change in face shape, stretch marks and skin which bruises easily. Cushing’s syndrome can also cause hypertension.

Corcept Therapeutics also shared that relacorilant was well-tolerated in the GRADIENT trial. It reported that there were no cases of relacorilant-induced hypokalemia, endometrial hypertrophy or related vaginal bleeding, adrenal insufficiency or QT prolongation.

The NDA submission for relacorilant for Cushing’s syndrome is expected this quarter. The GRADIENT trial will support results from the company’s GRACE trial, which were shared in June. The GRACE trial included 152 patients and met its primary endpoint of loss of hypertension control in the randomised-withdrawal phase.

Considering the results of the GRADIENT trial, Corcept Therapeutics’ chief development officer Bill Guyer said: “GRADIENT’s positive results in patients with Cushing’s syndrome confirm relacorilant’s promise as a significant medical advancement for the treatment of this deadly disease. As was true in the GRACE study, patients in GRADIENT who received relacorilant experienced clinically meaningful improvements in a broad range of hypercortisolism signs and symptoms, without suffering some of the serious adverse effects that can arise in patients taking currently approved treatments.

“These data will be a powerful addition to relacorilant’s NDA, which we plan to submit by year-end.”
