Increased intracellular or extracellular fluid in brain tissue. Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

Restoration of blood supply to tissue which is ischemic due to decrease in normal blood supply. The decrease may result from any source including atherosclerotic obstruction, narrowing of the artery, or surgical clamping. It is primarily a procedure for treating infarction or other ischemia, by enabling viable ischemic tissue to recover, thus limiting further necrosis. However, it is thought that reperfusion can itself further damage the ischemic tissue, causing REPERFUSION INJURY.

Transforming growth factor-alpha acting at the epidermal growth factor receptor reduces infarct volume after permanent middle cerebral artery occlusion in rats. (1/1215)

Transforming growth factor-alpha (TGF-alpha) is a ligand for the epidermal growth factor (EGF) receptor (EGFR), and is more abundant than EGF in the brain. The authors studied whether administration of exogenous TGF-alpha into the brain can protect neurons against ischemia in a model of permanent middle cerebral artery (MCA) occlusion in the rat, and whether any effect of TGF-alpha was mediated by EGFR by administering 4,5-dianilinophthalimide (DAPH), a protein-tyrosine kinase inhibitor with high selectivity for EGFR. Rats received either TGF-alpha (10 or 25 ng), DAPH (100 ng), DAPH plus TGF-alpha (25 ng), or vehicle in the ipsilateral first ventricle. Drugs were administered twice: 30 minutes before and 30 minutes after MCA occlusion, and infarct volume was evaluated 24 hours later. Transforming growth factor-alpha at the dose of 25 ng caused a statistically significant reduction of infarct volume (60%) in relation to ischemic rats administered vehicle. This reduction was no longer seen when TGF-alpha was administered in combination with DAPH. The present results show that TGF-alpha can protect neurons from ischemic damage, and that this effect is mediated by EGFR. It is suggested that activation of EGFR-mediated intracellular signalling pathways contributes to the survival of neural cells susceptible to ischemic injury.  (+info)

Computerised axial tomography in patients with severe migraine: a preliminary report. (2/1215)

Patients suffering from severe migraine, usually for many years, have been examined by the EMI scanner between attacks. Judged by criteria validated originally by comparison with pneumoencephalography, about half of the patients showed evidence of cerebral atrophy. Perhaps of more significance than generalised atrophy was the frequency of areas of focal atrophy and of evidence of infarction.  (+info)

Two similar cases of encephalopathy, possibly a reversible posterior leukoencephalopathy syndrome: serial findings of magnetic resonance imaging, SPECT and angiography. (3/1215)

Two young women who had encephalopathy that resembled reversible posterior leukoencephalopathy syndrome are presented. The brain magnetic resonance imaging (MRI) of these patients exhibited similar T2-high signal lesions, mostly in the white matter of the posterior hemispheres. Xe-SPECT during the patients' symptomatic period showed hypoperfusion in the corresponding areas, and angiography demonstrated irregular narrowing of the posterior cerebral artery. Clinical manifestations subsided soon after treatment, and the abnormal radiological findings also were almost completely resolved. Thus, we concluded that transient hypoperfusion followed by ischemia and cytotoxic edema might have had a pivotal role in these cases.  (+info)

Significance of acute cerebral swelling in patients with sylvian hematoma due to ruptured middle cerebral artery aneurysm, and its management. (4/1215)

A retrospective study of 75 patients treated surgically for ruptured middle cerebral artery (MCA) aneurysm within 48 hours evaluated clinical grade at admission, secondary development and management of cerebral swelling associated with space-occupying hematoma, cerebral infarction caused by vasospasm, development of hydrocephalus, and clinical outcome. Clinical grade at admission was significantly better in patients without than in those with hematoma (p < 0.01). Twenty-seven patients with sylvian hematoma caused by ruptured MCA aneurysm often developed ipsilateral cerebral swelling in the early period after subarachnoid hemorrhage. Seventeen of these patients developed serious cerebral swelling and received barbiturate therapy. Nine of these 17 patients had good outcome, but six patients died of cerebral swelling. The incidence of hydrocephalus was significantly higher in patients with than in those without hematoma (p < 0.01). The incidence of infarction was more pronounced in patients with sylvian hematoma. Clinical outcome was significantly better in patients without than in those with sylvian hematoma (p < 0.01). Development of cerebral swelling in patients with sylvian hematoma due to ruptured MCA aneurysm has a significant effect on outcome, and improvements in management are required.  (+info)

Cerebral blood flow in the monkey after focal cryogenic injury. (5/1215)

A focal cryogenic lesion was made in the left superior frontal gyrus of the anesthetized macaque brain. Cerebral blood flow (CBF) was determined by the hydrogen clearance technique before and during the 4 hours following trauma. Local CBF in tissue adjacent to the lesion increased in the first half hour after the lesion was made and then decreased during the ensuing 3 1/2 hours. Local CBF in the contralateral superior frontal gyrus, as well as total CBF and oxygen consumption, were unchanged by cryogenic trauma. The spread of vasogenic edema into uninjured tissue probably accounts for the observed decrease in local CBF. This experimental model may assist in discovering therapy to alter favorably the spatial and temporal profile of pathologic CBF changes in tissue surrounding an acute lesion of the brain.  (+info)

Abrupt exacerbation of acute subdural hematoma mimicking benign acute epidural hematoma on computed tomography--case report. (6/1215)

A 75-year-old male was hit by a car, when riding a bicycle. The diagnosis of acute epidural hematoma was made based on computed tomography (CT) findings of lentiform hematoma in the left temporal region. On admission he had only moderate occipitalgia and amnesia of the accident, so conservative therapy was administered. Thirty-three hours later, he suddenly developed severe headache, vomiting, and anisocoria just after a positional change. CT revealed typical acute subdural hematoma (ASDH), which was confirmed by emergent decompressive craniectomy. He was vegetative postoperatively and died of pneumonia one month later. Emergent surgical exploration is recommended for this type of ASDH even if the symptoms are mild due to aged atrophic brain.  (+info)

Epilepsy after two different neurosurgical approaches to the treatment of ruptured intracranial aneurysm. (7/1215)

One-hundred-and-fifty-two patients who underwent surgery for intracranial aneurysm were studied to determine the incidence of postoperative epilepsy in relation to the site of the aneurysm and the type of surgical approach. The overall incidence of epilepsy was 22%. Of the 116 patients treated by the intracranial approach 27.5% developed epilepsy, in contrast with only 5% of the 36 patients who had carotid artery ligation in the neck. Epilepsy occurred most frequently (35%) with middle cerebral artery aneurysms, especially if moderate or severe operative trauma was sustained and there was postoperative dysphasia.  (+info)

Glial and capillary density of the pontine white matter in swelling and atrophy. (8/1215)

A total of 48 autopsied brains were morphometrically examined for the relation between pontine geometry and structural parameters. In each case, the numerical density of neuroglial cells Nv(G) and the linear density of capillary network Lv(C) of the pontine white matter were determined stereologically from the counts of glial nuclear profiles and capillary transections per constant area of a histological section with a constant thickness. It was revealed that in general the glial numerical density increased with advancing atrophy and decreased with increasing swelling, whereas the capillary linear density remained fairly constant especially in the advanced stage of brain swelling. Further analysis of this relation using a model of pontine geometry has made it clear that the total capillary length in the swollen white matter increases probably at the expense of the capillary caliber as swelling advances. The changes in the ratio Lv(C)/Nv(G) under pathological conditions are emphasized and possible utility of classifying stages of acute brain swelling from a viewpoint of microvascular dimension is suggested.  (+info)

Aquaporin 4 (AQP4), the most abundant water channel protein in the brain, is involved in brain edema induced by ischemic insults. To evaluate whether the neuroprotective effects of estrogen are associated with AQP4 expression and edema formation, changes in AQP levels and ischemic edema were examined in the brains of male and female mice subjected to transient middle cerebral artery occlusion. Infarct volume and edema formation were markedly less in females than in males. AQP4 expression in the ischemic cortex of females was relatively well preserved, whereas it was significantly decreased in males. These effects disappeared in ovariectomized females but were reversed by estrogen replacement. Furthermore, AQP4 expression was decreased with increased brain edema in females treated with ICI182,780, an estrogen receptor antagonist. These findings suggest that the estrogen effect on the reduction of ischemic brain edema is associated with the preserved level of AQP4 that is partly mediated by ...
Bradykinin as the major product of the contact-kinin system triggers inflammation and brain edema formation (for a comprehensive overview, see [2]). In this study, we aimed at targeting FXIIa, the very first step required for activation of this pathway in the plasma to alleviate pathological events leading to secondary injury after brain trauma.. Following brain trauma, bradykinin levels in the cerebrospinal fluid of patients are markedly elevated up to 48 h and decrease thereafter, reaching levels of the control group within 72 h after injury [19]. Similar to the human situation, bradykinin levels maximally increase within 2 h in the brain tissue of mice after experimentally induced focal brain trauma and then subsequently decline [7]. In accordance, we observed that plasma bradykinin levels increased twofold to threefold within 2 h after focal cortical injury in mice. As FXIIa activates plasma kallikrein, it is plausible to assume that posttraumatic bradykinin release is dependent on the ...

To evaluate the location and early time course for development of cerebral edema following therapy for diabetes, streptozotocin-diabetic rats were subjected to constant i.v. infusion with saline and regular insulin. At the end of 1, 2, and 5 h of therapy, these rats were killed and tested for density of the cerebral cortex, subcortical white matter, caudate-putamen, thalamus, and medulla. Density data from treated animals were compared with those from control animals. From these data, change in brain tissue volume as water was calculated.. Diabetic animals killed after 1 h of fluid and insulin therapy demonstrated a modest increase in brain water content of all areas tested except white matter. Following 2 h of therapy, all regions tested were edematous, with a magnitude of edema that was similar to that seen at 1 h. After 5 h of therapy, there was further increase in water content of the cerebral cortex, but not the other regions examined. Treatment with saline alone did not result in central ...
The selection of an inversion recovery pulse sequence as well as particular values of the parameters for measurement of brain water have been derived after extensive studies with calibration standards of known relaxation times and in vivo infusion edema animal models. Most importantly, the technique has been validated in man.

Aquaporins are a family of water channel proteins that provide a major pathway for osmotically driven water transport through cell membranes. So far, 13 aquaporin isoforms (AQP0-AQP12) have been identified in mammalian species (Verkman, 2005). AQP4, the predominant isoform in adult brain, is primarily expressed at the border between brain parenchyma and major fluid compartments, including astrocyte foot processes and glia limitans, as well as ependymal cells and subependymal astrocytes (Venero et al., 2001). The bidirectional water channel AQP4 has an important role in water homeostasis in the brain. It probably helps in the redistribution and absorption of edema fluid, because disruption of AQP4 is found to contribute to the pathophysiology of brain edema (Zador et al., 2007). AQP4 knockout markedly reduced brain swelling in mouse models of cytotoxic brain edema, whereas it significantly worsened outcome in mouse models of vasogenic brain edema (Papadopoulos and Verkman, 2007). Thus, AQP4 ...
In the present study, we evaluated early brain injury: BBB disruption, brain edema, brain tissue death, as well as mortality and neurological deficits. Cell death, especially apoptosis, occurred in neuronal tissues, particularly in the hippocampus and basal cortex adjacent to the blood deposits. Neuronal cell death contributes to cytotoxic edema, which usually develops early after brain injury.20 In the meantime, BBB permeability was enhanced as shown by extravasations of Evans blue dye, probably because of endothelial apoptosis. BBB breakdown leads to vasogenic brain edema after SAH.4 z-VAD-FMK abolished caspase-3 and TUNEL staining in cerebral endothelial cells and reduced IgG leaking after SAH. Apoptotic death of cerebral endothelial cells might have important impact on neurological functions because z-VAD-FMK improved neurological outcome at 24 hours.. After initial bleeding, apoptosis of brain tissues may be caused by elevated intracranial pressure (ICP), toxicity of blood components,5 ...
We develop novel neuroimaging tools to better quantify brain edema and blood-brain barrier integrity in the setting of cerebral ischemia. By creating high specificity methods using non-invasive imaging, we have advanced our understanding of the role brain edema plays in modulating neurological recovery after stroke. These studies have revealed that brain edema may impact recovery in up to 25% of all stroke patients. Our imaging tools not only provide insight into the pathophysiology of secondary brain injury, but can also serve as intermediate endpoints in clinical trials as part of proof of concept studies for anti-edema treatments.. ...
Treatments to improve the neurological outcome of edema and cerebral ischemic stroke are severely limited. Here, we present the first in vivo single cell images of cortical mouse astrocytes documenting the impact of single vessel photothrombosis on cytotoxic edema and cerebral infarcts. The volume of astrocytes expressing green fluorescent protein (GFP) increased by over 600% within 3 hours of ischemia. The subsequent growth of cerebral infarcts was easily followed as the loss of GFP fluorescence as astrocytes lysed. Cytotoxic edema and the magnitude of ischemic lesions were significantly reduced by treatment with the purinergic ligand 2-methylthioladenosine 5′ diphosphate (2-MeSADP), an agonist with high specificity for the purinergic receptor type 1 isoform (P2Y1R). At 24 hours, cytotoxic edema in astrocytes was still apparent at the penumbra and preceded the cell lysis that defined the infarct. Delayed 2MeSADP treatment, 24 hours after the initial thrombosis, also significantly reduced cytotoxic

In the present study we first elucidated the NTN‐1-mediated signaling pathway in BBB protection following SAH in rats. Our results showed that endogenous NTN‐1 and DCC receptor were upregulated in the early stage after SAH. Exogenous NTN‐1 treatment reduced brain edema and BBB permeability and thereby alleviated neurological deficits after SAH, which were accompanied by an increase in FAK phosphorylation and a decrease in RhoA activity as well as endothelial junction protein upregulation. In contrast, silencing of endogenous NTN‐1 by special siRNA exacerbated brain edema, BBB disruption, and neurological deficits. Furthermore, knockdown DCC using DCC siRNA or inhibition of FAK by Fib‐14 abolished the neuroprotective effects of exogenous NTN‐1 on BBB integrity and brain edema formation, which were associated with the increased RhoA activity and MMP‐9 and the degraded endothelial junction proteins and basal lamina at 24 hours after SAH. Taken together, these findings support our ...

We investigated the in vivo ramifications of a book aquaporin 4 (AQP4) inhibitor 2-(nicotinamide)-1,3,4-thiadiazole, TGN-020, inside a mouse style of focal cerebral ischemia using 7. research convincingly exhibited that pretreatment using the AQP4 inhibitor TGN-020 considerably reduced the quantity of mind edema connected with ischemic damage. Ischemic edema is usually thought to be initiated by influx of Na+ connected with energy failing. Higher osmolarity circumstances create the generating force for drinking water influx into cells, leading to ionic edema [17]. This early edema stage, so-called cytotoxic edema, is certainly thought to last a long time before mass leakage of drinking water into the human brain ensues, making so-called vasogenic edema [18]. AQP4 is certainly thought to play a substantial function in the real drinking water flux in both procedures. Flux through AQP4 is certainly buy 154992-24-2 bidirectional and solely reliant on osmolarity distinctions between your two spaces ...

OBJECTIVES: A novel method of long-term telemetric monitoring of mean arterial pressure (MAP) and intracranial pressure (ICP) for the determination of current cerebral perfusion pressure (CPP) and the time course of ICP in freely moving rats under physiological conditions and with increased ICP due to the induced cerebral edema were studied. METHODS: The brain edema, that caused volume enlargement and ICP elevation was achieved in entirely experimental conditions without any parallel pathological process. Vasogenic/extracellular edema was induced by osmotic blood-brain barrier disruption (BBBd) and for induction of cytotoxic/intracellular edema the water intoxication model (WI) was used. RESULTS: The results showed significantly elevated values of ICP both in conditions of osmotic blood-brain barrier disruption (BBBd model) and cytotoxic/intracellular edema (WI model) compared to intact rats. The average values of ICP were significantly higher in WI model compared to osmotic BBBd model. Distinct ...

This is the first population based study of cerebral oedema. The overall risk of cerebral oedema was estimated to be 7 per 1000 episodes of DKA. The risk was 4 per 1000 in previously diagnosed diabetics and 12 per 1000 in those with newly diagnosed diabetes. Although there was no evidence that the risk of cerebral oedema was related to age, sex, or season of occurrence, there was a non-significant trend towards an increased risk in younger patients, who tend to be the most ill at diagnosis.15 A longer period of surveillance would be required to confirm this. Of the 126 reports to the BPSU, questionnaires were not returned on four; it is very unlikely that these would relate to any further cases of cerebral oedema as the consultants or junior staff involved could not recall any cases. Thus we are confident that we have discovered all possible cases of cerebral oedema during the period of the study.. The denominator (DKA episodes) for these calculations was determined independently of the ...

The Role of Blood-Brain Barrier Damage in the Pathogenesis of Contrast-Induced Encephalopathy., Guilian Zhang, Heying Wang, Tao Li, Jiao Liu, Lili Zhao, Man Sun, Yating Jian
Neuromyelitis optica (NMO) is an autoimmune disorder of the central nervous system, which is characterized by autoantibodies directed against the water channel aquaporin-4 (AQP4). As one of the main water regulators in the central nervous system, APQ4 is supposed to be involved in the dynamics of brain edema. Cerebral edema seriously affects clinical outcome after ischemic stroke; we therefore aimed to investigate whether NMO-antibodies may exert the same functional effects as an AQP4-inhibitor in-vivo in acute ischemic stroke. Sixteen male Wistar rats were randomized into two groups twice receiving either purified NMO-IgG or immune globulin from healthy controls, 24 hours and 30 minutes before middle cerebral artery occlusion (MCAO) was performed. T2-weighted MRI was carried out 24 hours after MCAO. MRI-examination showed a significant increase of infarct size in relation to the cerebral hemisphere volume with NMO-IgG treated animals (27.1% ± 11.1% vs. 14.3% ± 7.2%; p < 0.05) when corrected for the
Our results identify a water channel protein as the first defined autoantigen pertinent to an inflammatory demyelinating disorder of the human CNS. AQP4 is an integral protein of astrocytic plasma membranes (15-18), and is highly concentrated in foot process domains facing microvessels where it interacts with dystrophin-associated proteins (10, 17). The AQP4 channel is mercurial-insensitive, and is the predominant water channel in the CNS. It has a pathophysiologic role in brain edema formation following water intoxication (14, 19, 20) or focal cerebral ischemia (21). Brain edema occurring in oncologic contexts is attributed to the up-regulation of AQP4 in high-grade astrocytomas and in reactive astrocytes related to cerebral adenocarcinoma metastases (21, 22).. The present study is the first to implicate AQP4 in the pathogenesis of any autoimmune disorder. NMO may represent the first example of a novel class of autoimmune channelopathies. Unlike MS, the cerebrospinal fluid in patients who have ...

Cerebral oedema (CO) is the most dreaded complication of diabetic ketoacidosis (DKA) in children. Despite advances in many areas of the management of DKA, the mortality from CO has remained fairly constant for the past six decades.1-4 Mortality estimates vary widely, but some authors suggest this disorder is lethal in about 20% to 50% of victims.5,6 Fortunately, it is a rare occurrence, complicating about 1% of cases of DKA in children.5 Since it was first described in 1936, much effort has gone into the search for a cause for this condition.7 Despite these attempts, CO in childhood DKA remains a mysterious illness. It is unpredictable, sporadic, and deadly.. Researchers have suggested that the treatment for DKA may be causally related to the development of CO.3,4,8-12 The theory suggests that overzealous insulin use or hydration with excess free water administration to children with DKA cause a dramatic dysequilibrium between the osmolality of the serum and that of the brain. A fluid shift ...

blood-brain barrier (BBB). In the normal cerebral vasculature, endothelial tight junctions associated with astrocytes create an impermeable barrier (the BBB), through which access into the brain interstitium is dependent upon specific transport mechanisms. The BBB may be compromised in ischemia, trauma, infection, and metabolic derangements. Typically, vasogenic edema develops rapidly following injury. Cytotoxic edema refers to cellular swelling and occurs in a variety of settings, including brain ischemia and trauma. Early astrocytic swelling is a hallmark of ischemia. Brain edema that is clinically significant usually represents a combination of vasogenic and cellular components. Edema can lead to increased ICP as well as tissue shifts and brain displacement from focal processes (Chap. 274). These tissue shifts can cause injury by mechanical distention and compression in addition to the ischemia of impaired perfusion consequent to the elevated ICP. ...

I know it sounds obvious. But in cerbral oedema lets say due to vasgenic cause,the problem is cerebral vessels becoming more permeable and leaking out blood to extravascular compartment. Now how does the brain get bigger due to this. I mean for brain to get bigger, the intracellular fluid volume of brain cells must increase. So when these capillaries leak blood out, do near by brain cells absorb these water, increasing their intracellular volume and as a result we get enlarged brain? or does this leaked out fluid get stuck in brain interstitium making it bigger. I hope u understand my confusion, because leaking out fluid must make brain smaller otherwise. Thanks ...

An independent safety monitoring committee has found that patients with AD given the highest dose of an experimental monoclonal antibody, bapineuzumab, were more likely to develop cerebral vasogenic edema; the highest dose was subsequently discontinued from the clinical trial (Salloway et al., 2009). The Food and Drug Administration has also posted concerns regarding the safety of immunotherapy approaches, stating that microhemorrhage susceptibility is a risk factor for vasogenic edema. This highlights the importance of such safety assessments while developing immunotherapy strategies for the treatment of AD.. Although the diagnosis of microhemorrhages in human brain by gradient-echo sequence or T2*-weighted MRI (Offenbacher et al., 1996; Fazekas et al., 1999; Greenberg et al., 2004) has been established, the preclinical identification of cerebral microhemorrhage is challenging because microhemorrhage in a mouse brain is approximately two orders of magnitude smaller (in the range 20 to 400 μm) ...

Aquaporin-4 (AQP4) is the major water channel in the central nervous system and plays an important role in the brains water balance, including edema formation and clearance. There are 6 splice variants; the shorter ones assemble into functional, tetrameric square arrays; the longer is palmitoylated on N-terminal cysteyl residues) (Suzuki et al., 2008). The longest, Aqp4e, has a novel N-terminal domain and forms a water channel in the plasma membrane although various shorter variants dont (Moe et al., 2008). AQP4, like AQP0 (1.A.8.8.2), forms water channels but also forms adhesive junctions (Engel et al., 2008) (causes cytotoxic brain swelling in mice (Yang et al., 2008)) Mice lacking Aqp4 have impaired olfactions (Lu et al., 2008). Aqp4 is down regulated in skeletal muscle in muscular dystrophy (Au et al. 2008). The crystal structure is known to 2.8 Å resolution (Tani et al., 2009). The structure reveals 8 water molecules in each of the four channels, supporting a hydrogen-bond isolation ...

Tammy, please take heart and please, please give yourself some time to recover. It is amazing how the brain can recover from things. After my sons last chemo treatment, he was so ill. He had serious brain edema...a lot of swelling. This is how bad he was: he was in diapers. He could not talk, could not say his name, could not feed himself, could not walk. He was sitting and drooling. He would stare off into space and it seemed like he was not aware we were in the room. He would do purposeless random repetitive motions like tapping or rocking. I thought his life as it had been was over...that our David was lost to us. He was like a stranger to us.. Well, he recovered, Tammy. He came back from all of that. He is back just about 100%. He still has quite a bit of fatigue and hes pretty weak, but thats improving too. Its unbelievable. The doctors said thats what brain swelling will do to you. I dont know if you have issues with swelling but that could be part of your problem since its common ...
Background: Pioneer studies demonstrate the impact of extreme sport load on the human brain, leading to threatening conditions for athletes health such as cerebral edema. The investigation of brain water diffusivity, allowing the measurement of the intercellular water and the assessment of cerebral edema, can give a great contribution to the investigation of the effects of extreme sports on the brain. We therefore assessed the effect of supra-physiological effort (extreme distance and elevation changes) in mountain ultra-marathons (MUMs) athletes combining for the first time brain magnetic resonance imaging (MRI) and blood parameters.. Methods:This longitudinal study included 19 volunteers (44.2 ± 9.5 years) finishing a MUM (330 km, elevation + 24000 m). Quantitative measurements of brain diffusion-weighted images (DWI) were performed at 3 time-points: Before the race, upon arrival and after 48 h. Multiple blood biomarkers were simultaneously investigated. Data analyses included brain apparent ...

In March, Juno Therapeutics (NASDAQ:JUNO) announced that it was ending development of JCAR015 after five patients with acute lymphoblastic leukemia (ALL) died from cerebral edema -- brain swelling -- in its phase 2 clinical trial. The lethal side effect made it unlikely the treatment could get approved, despite extremely strong efficacy data.. After a review of the data, the company said it thought there were protocol modifications and process improvements that would hopefully make JCAR015 safer, but those changes would require Juno to go back to phase 1. Since the biotech has other drug candidates to treat ALL, Juno made a decision with its partner Celgene (NASDAQ:CELG) that it would be best to shelve JCAR015 and focus on the other ALL therapies.. All told, the biotech spent $46.4 million on the failed drug, which could end up being a little higher depending on wrap-up costs. ...
