FDA grants breakthrough device designation to artificial intelligence software for CTEPH pattern recognition from Bayer and MSD

[ad_1]

BayerBayer announced today that the U.S. Food and Drug Administration (FDA) granted Breakthrough Device Designation to the Artificial Intelligence Software for Chronic Thromboembolic Pulmonary Hypertension (CTEPH) Pattern Recognition, which Bayer is currently developing jointly with MSD (tradename of Merck & Co., Inc., Kenilworth, N.J., USA).


A rare form of pulmonary hypertension, CTEPH affects an estimated 8 to 40 people per million globally. CTEPH can be difficult to diagnose because its symptoms are similar to those of other lung diseases. Being a rare disease, physicians may not always recognize CTEPH due to factors including a lack of clinical awareness and complex findings involving the heart, lung and pulmonary vessels. Computed tomography pulmonary angiography (CTPA) as well as a ventilation/perfusion scan (V/Q scan) are common diagnostic modalities to detect CTEPH. Radiologists may have the first opportunity to identify CTEPH in patients; therefore it is vital that they recognize CTEPH indicators on CTPA images.


Development of the software will rely on using deep learning methodology to support radiologists by identifying signs of CTEPH in CTPA scans. The software processes image findings of cardiovascular, lung perfusion and pulmonary vessel analyses in combination with the patient’s history of pulmonary embolism. If the development is successful, the software could be deployed via Bayer’s Radimetrics™, an informatics technology platform that connects contrast medium with injector and scan information to provide important insights.


“Bayer is looking forward to leveraging our expertise in Radiology to develop a software to support radiologists and treating physicians in the complex diagnostic decision making process of this rare disease,” said Prof. Dr. Olaf Weber, Head of Radiology Research & Development of Bayer AG’s Pharmaceuticals Division. “We hope that greater awareness of CTEPH in conjunction with a decision-support tool will eventually assist in diagnosing patients earlier and more reliably, thereby allowing earlier treatment.”


The FDA Breakthrough Device Program is intended to help patients have more timely access to devices and breakthrough technologies that provide for more effective treatment or diagnosis for life-threatening or irreversibly debilitating diseases by expediting their development, assessment, and review. While the FDA Breakthrough Device Designation is expected to expedite the software’s assessment and review, its development remains complex given the nature of the disease and technology.

About Chronic Thromboembolic Pulmonary Hypertension (CTEPH)


CTEPH is a progressive type of pulmonary hypertension, in which it is believed that thromboembolic occlusion (organized blood clots) of pulmonary vessels gradually builds up and subsequently leads to an increased blood pressure in the pulmonary arteries, resulting in an overload of the right heart. CTEPH may evolve after prior episodes of acute pulmonary embolism (PE). The standard and potentially curative treatment for CTEPH is pulmonary thromboendarterectomy (PTE), a surgical procedure in which the blood vessels of the lungs are cleared of clot and scar material. However, a considerable number of patients with CTEPH (20%-40%) are not operable and in up to 35 percent of patients, the disease persists or reoccurs after PTE.


As many as 1 out of every 25 people who had a PE (even if they were treated with at least 3 months of anticoagulants) could go on to develop CTEPH. Symptoms of CTEPH include shortness of breath, edema, fatigue, and chest pain and are therefore similar to other, more common diseases, resulting in an often delayed diagnosis of CTEPH.


Bayer and MSD are in a worldwide collaboration in the field of sGC modulators with the goal to fully evaluate this therapeutic class in areas of unmet medical need.

Lilly submits New Drug Application to the FDA for lasmiditan for acute treatment of migraine, receives Breakthrough Therapy Designation for Emgality™ (galcanezumab-gnlm) for prevention of episodic cluster headache

[ad_1]

Eli Lilly and CompanyEli Lilly and Company (NYSE: LLY) has announced the submission of a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for lasmiditan for the acute treatment of migraine with or without aura in adults. Lasmiditan is an investigational, oral, centrally-penetrant, selective serotonin 5-HT1F agonist that is structurally and mechanistically distinct from other approved migraine therapies and lacks vasoconstrictive activity. It is the first and only molecule in the “-ditan” class under evaluation for the acute treatment of migraine in adults. If approved, it could represent the first significant innovation for the acute treatment of migraine in more than two decades.


Lilly also plans to submit an sBLA to the FDA for Emgality for the preventive treatment of episodic cluster headache in adults by the end of the year. The FDA has granted Breakthrough Therapy Designation to Emgality for episodic cluster headache. Breakthrough Therapy Designation is a process that is intended to expedite the development and review of drugs that treat serious or life-threatening diseases and, based on preliminary clinical evidence, may demonstrate substantial improvement over available therapies. Currently, there are no approved preventive treatments for episodic cluster headache in the U.S.


“Headache disorders like migraine and cluster headache affect each person differently, and many patients spend years cycling through different medications to effectively diagnose and treat their symptoms,” said Gudarz Davar, M.D., vice president, Neurology Development, Lilly Bio-Medicines. “Lilly has spent the last 25 years researching innovative therapies to treat headache disorders, and we are thrilled to be one step closer to potentially providing new and different options with lasmiditan for the acute treatment of migraine and Emgality for the preventive treatment of episodic cluster headache.”


The NDA for lasmiditan includes data from two Phase 3 single-attack studies (SAMURAI and SPARTAN), which evaluated the safety and efficacy of lasmiditan for the acute treatment of migraine. In both studies, at two hours following the first dose of lasmiditan, the percentage of patients who were migraine pain-free was significantly greater compared to placebo. These results were significant across all studied doses. Lasmiditan also met the key secondary endpoint, with a significantly greater percentage of patients free of their most bothersome symptom (MBS) compared with placebo at two hours following the first dose. In these studies, patients chose their MBS from sensitivity to light, sensitivity to sound or nausea. The most commonly reported adverse events after lasmiditan dosing were dizziness, paresthesia, somnolence, fatigue, nausea, muscle weakness and numbness. Data from these studies were presented at the American Headache Society (AHS) annual meeting and the American Academy of Neurology (AAN) annual meeting.


“As a caregiver for someone living with chronic migraine, I know firsthand how disabling headache diseases can be,” said Kevin Lenaburg, executive director of the Coalition For Headache And Migraine Patients (CHAMP). “We’re excited about the new innovations in the acute treatment of migraine and the preventive treatment of migraine and episodic cluster headache, and we’re thankful for Lilly’s commitment to continue to investigate and hopefully bring these important new therapeutic options to market.”


Lasmiditan and Emgality represent two of three treatments in Lilly’s pain portfolio. Emgality was approved by the FDA in September 2018 for the preventive treatment of migraine in adults. The portfolio also includes tanezumab, developed in partnership with Pfizer, which is currently being investigated for the treatment of osteoarthritis pain, chronic low back pain and cancer pain.


Please see Full Prescribing Information, including Patient Information, for Emgality. See Instructions for Use included with the pen and prefilled syringe.

About Migraine


Migraine is a disabling, neurologic disease characterized by recurrent episodes of severe headache accompanied by other symptoms including nausea, vomiting, sensitivity to light and sound, and changes in vision.(1,2) More than 30 million American adults have migraine, with three times more women affected by migraine compared to men.(3,4,5,6) According to the Medical Expenditures Panel Survey, the total unadjusted cost associated with migraine in the U.S. is estimated to be as high as $56 billion annually, yet migraine remains under-recognized and under-treated.(3,7,8)

About Cluster Headache


Cluster headache is a disabling primary headache disorder composed of recurrent “attacks” of intense headaches on one side of the head, frequently associated with pain behind or around one eye, restlessness and agitation.(9,10) Cluster headache attacks typically last between 15 to 180 minutes, occurring near daily to multiple times daily during a cluster period.(9) It is estimated that 85 to 90 percent of cluster headache cases are classified as “episodic,” while the remaining 10 to 15 percent are classified as “chronic.” Diagnostically, episodic cluster headache and chronic cluster headache are differentiated based on the duration of remission periods.(9)

About Lasmiditan


Lasmiditan is an investigational, first-in-class molecule under evaluation for the acute treatment of migraine. Lasmiditan uses a novel mechanism of action which selectively targets 5-HT1F receptors, including those expressed in the trigeminal pathway, and has been designed for the acute treatment of migraine without the vasoconstrictor activity associated with some migraine therapies. Data from two Phase 3 single-attack studies (SAMURAI and SPARTAN) have been presented at the American Headache Society (AHS) annual meeting and the American Academy of Neurology (AAN) annual meeting. In March 2017, Lilly completed the acquisition of CoLucid Pharmaceuticals, including lasmiditan, which was originally discovered at Lilly.

About Emgality


Emgality is a humanized monoclonal antibody that binds to calcitonin gene-related peptide (CGRP) and blocks its binding to the receptor. Emgality offers a once-monthly, self-administered, subcutaneous injection.

Breakthrough neurotechnology for treating paralysis

[ad_1]

Three paraplegics who sustained cervical spinal cord injuries many years ago are now able to walk with the aid of crutches or a walker thanks to new rehabilitation protocols that combine targeted electrical stimulation of the lumbar spinal cord and weight-assisted therapy. This latest study, called STIMO (STImulation Movement Overground), establishes a new therapeutic framework to improve recovery from spinal cord injury. All patients involved in the study recovered voluntary control of leg muscles that had been paralyzed for many years. Unlike the findings of two independent studies published recently in the United States on a similar concept, neurological function was shown to persist beyond training sessions even when the electrical stimulation was turned off. The STIMO study, led by the Ecole Polytechnique Fédérale de Lausanne (EPFL) and the Lausanne University Hospital (CHUV) in Switzerland, is published in the 1 November 2018 issues of Nature and Nature Neuroscience.


“Our findings are based on a deep understanding of the underlying mechanisms which we gained through years of research on animal models. We were thus able to mimic in real time how the brain naturally activates the spinal cord,” says EPFL neuroscientist Grégoire Courtine.


“All the patients could walk using body weight support within one week. I knew immediately that we were on the right path,” adds CHUV neurosurgeon Jocelyne Bloch, who surgically placed the implants in the patients.


“The exact timing and location of the electrical stimulation are crucial to a patient’s ability to produce an intended movement. It is also this spatiotemporal coincidence that triggers the growth of new nerve connections,” says Courtine.


This study achieves an unprecedented level of precision in electrically stimulating spinal cords. “The targeted stimulation must be as precise as a Swiss watch. In our method, we implant an array of electrodes over the spinal cord which allows us to target individual muscle groups in the legs,” explains Bloch. “Selected configurations of electrodes are activating specific regions of the spinal cord, mimicking the signals that the brain would deliver to produce walking.”


The challenge for the patients was to learn how to coordinate their brains’ intention to walk with the targeted electrical stimulation. But that did not take long. “All three study participants were able to walk with body-weight support after only one week of calibration, and voluntary muscle control improved tremendously within five months of training”, says Courtine. “The human nervous system responded even more profoundly to the treatment than we expected.”

Helping the brain help itself


The new rehabilitation protocols based on this targeted neurotechnology lead to improved neurological function by allowing the participants to actively train natural overground walking capabilities in the lab for extensive periods of time, as opposed to passive training like exoskeleton-assisted stepping.


During rehabilitation sessions, the three participants were able to walk hands-free over more than one kilometer with the help of targeted electrical stimulation and an intelligent bodyweight-support system. Moreover, they exhibited no leg-muscle fatigue, and so there was no deterioration in stepping quality. These longer, high-intensity training sessions proved crucial for triggering activity-dependent plasticity – the nervous system’s intrinsic ability to reorganize nerve fibers – which leads to improved motor function even when the electrical stimulation is turned off.


Previous studies using more empirical approaches, such as continuous electrical stimulation protocols, have shown that a select few paraplegics can indeed take steps with the help of walking aids and electrical stimulation, but only over short distances and as long as the stimulation is on. As soon as the stimulation is turned off, the patients immediately return to their previous state of paralysis and are no longer able to activate leg movements.

Next steps


The startup GTX medical, co-founded by Courtine and Bloch, will use these findings to develop tailored neurotechnology with the aim to turn this rehabilitation paradigm into a treatment available at hospitals and clinics everywhere. “We are building next-generation neurotechnology that will also be tested very early post-injury, when the potential for recovery is high and the neuromuscular system has not yet undergone the atrophy that follows chronic paralysis. Our goal is to develop a widely accessible treatment,” adds Courtine.
