AMRA Medical Research Reveals New MRI-based Data Connected to Risk for Coronary Heart Disease at The Liver Meeting Digital Experience – PRNewswire

The researchers measured the visceral adipose tissue (VAT) and liver fat (LF) from magnetic resonance images of 12,276 participants from the UK Biobank, the researchers assessed and divided individuals into four groups defined by sex-specific median values of VAT and LF: low VAT-low LF, low VAT-high LF, high VAT-low LF, and high VAT-high LF. Participants were followed for 1.3 years (on average) to detect VAT-LF groups' associations with CHD incidence.

In total, 176 CHD events were recorded, revealing that high visceral adiposity increased risk for CHD; this effect was exacerbated in those who also had low liver fat elevating the risk for CHD greater than two-fold compared with low VAT-low LF. High liver fat in combination with low visceral adiposity (low VAT-high LF), did not increase the risk for CHD. After adjusting for age and body mass index, high VAT-high LF association with CHD diminished, but the increased risk of CHD among those with high VAT-low LF persisted.

"We believe knowledge of patient risk for disease is limited when assessment is restricted to single, isolated fat depots. When developing NAFLD treatments, a decrease in liver fat alone may not be sufficient to lower patients' cardiometabolic risk. In fact, the research shows that decreasing liver fat without resolving visceral obesity may put the patient at greater risk of heart disease. This is what we want to investigate further,"stated Jennifer Linge, Lead Scientist, Personalized Medicine at AMRA Medical.

The results suggest that heterogeneity of body fat distribution affects CHD risk. Specifically, risk for CHD increased among those with high visceral adiposity, which intensifies in the presence of low liver fat indicating that liver triglyceride regulation plays a vital role in cardiovascular health in the context of visceral obesity.

Learn more about these findings by viewing the recorded presentation. The corresponding abstract "Can Low Liver Fat Be Bad for Your Heart? The High Visceral Fat, Low Liver Fat Phenotype: A Risk Factor for Coronary Heart Disease" (number 89) can be found in the journal HEPATOLOGY.

A rare disease almost killed him but this Phoenix rocker’s friends are helping him survive – The Arizona Republic

Ryan Butler was 19 and playing guitarin two touring bands on the heavier end of the musical spectrum Wellington and Unruh when he lost his mother to Wilson's disease, agenetic disorderin which excesscopperbuilds up in the body and eats through the liver.

He had just turned 43, the age at which his motherdied, when a doctor confirmed what Butler had already long suspected.

He, too, had contracted a disease so rare a liver doctor told him he would more than likely be the only Wilson's patient the doctor'sstaff would ever see.

This was in August 2019, after six years of regular visitstoa hematologist for what hesays were "really low platelets," a sign of a liver disorder.

As the guitarist recalls, "I told him over and over 'My mom passed from Wilson's and I know it can be passed down genetically, even though it's rare. Please check me.' 'Oh, no, you don't have Wilson's.' Over and over with this guy. And he could never figure out what was wrong with me."

Then, the eye problems started.

"I got acute angle glaucoma, out of nowhere, and lost the vision in one eye," Butler says. "I was getting all kinds of weird sicknesses and fevers. And the eye doctor was like 'There's something wrong with you. You need to figure out what's going on.'"

That's when a trip to thegastroenterologist confirmed his worst fears.

As Butler recalls, "That doctorwas like, 'You have Wilson's disease. I'm gonna send you to a liver specialist right away."

It's been a month since Butler's liver transplant.

"I feel pretty lucky to have gotten this far through it," he says of life with Wilson's.

"The month before I got the transplant, theystopped having me take medicine. None of it was working anymore because my liver couldn't metabolize it. It was just so shot. So it's pretty intense. You degrade slowly over time. And then it just hits you."

Normal platelet levels are about 200, Butler says. Before the transplant, his were in the 50s. Now they're back in the 170s and 180s.

"I'm pretty much couchbound," he says. "In my head, I feel so much better but then I try to move around and it's like, 'Oh yeah, I'm not feeling good.'"

As he continues to recover, Butler will be facing major medical expenses.

"I haven't worked in months because I've been so sick," he says.

"I've given almost everything I've made these last two years to doctors and a dentist to get ready for the transplant. And my wife hasn't worked in months because she's been taking care of me. And the bills just keep coming when you go through something like this."

He was told that the cost ofthe medication alone will be enough for him to meet his $7,000 deductible every January.

"I don't exactly have that just sitting around for fun," he says. "So I'm gonna have to figure that out every year from now on."

In the meantime, his friends in the music community have come to Butler's aid with a virtual benefit concert they've called Butler Fest at 3 p.m. Saturday, Nov. 21, to help him cover medical expenses.

Among the artists who came forward with exclusive filmed performances are Jim Adkins of Jimmy Eat World, Exhumed, Dropdead, Fall Silent, Papa M, Austin Lunn of Panopticon, Bobb Bruno of Best Coast, Goya, Lago, Sorrower and Broloaf.

Broloaf is the last band Butler did a show with, playing Cro Mags covers at the Yucca Tap Room as part of their Halloween weekend festivities in 2019.

"And I had had my biopsy on my liver a few days before that," Butler recalls. "And I was puking in the trash can before our set. I was actually talking with one of the guitarists from Broloaf about starting a new band. And after that, I was like, yeah, I'm not gonna be playing for a while."

Another former bandmate,Danny Marianino of North Side Kings, is contributing a set of standup comedy.

And it was yet another former bandmate, Matt Martinez of Landmine Marathon, whoapproached him about the idea of putting a benefit show together. He enlisted the aid and technical support ofMichelle Donovan at the Nile Theatre in Mesa, where many of the sets are being filmed.

"Matt kind of just surprised me with the lineup," Butler says. "He was like, I'm gonna do a benefit to stream online. And I was like, 'OK.'"

Then he showed him the lineup.

"And I was like, 'Are you kidding me?,' Butler recalls with a laugh. "So it was a real shocker. And it really kind of reflects my musical tastes, honestly. It's all over the map."

It's been an overwhelming experience for Butler to see these people come together in his hour of need.

"A guy like Jim Adkins or Papa M, it's hard to believe they would taketime out of their day to film a set for me," he says.

"Exhumed is a big death metal band. They had to fly their drummer out to do it. It's just pretty amazing that they're coming together just to help me out. It really feels special. I'm just glad I'm well enough that I'll be able to kind of enjoy it."

Martinez figures he's known Butler almost 30 years.

"Just through punk rock and playing in bands when we were in high school, crossing paths," he says. "Our previous bands in the '90s played together a lot. And even before he was in Landmine, he recorded Landmine in his studio."

Getting a benefit together for his friend was pretty much a given for Martinez, who also started a GoFundMe for Butler in late August.

"I've experienced extreme life-changing medical events, and I know how our healthcare system works," he says.

"I knew there was gonna be a huge financial burden associated with not only the procedure itself but the aftereffects, the healing process, not being able to go to work immediately. So I networked with Michelle and we brainstormed ways to make a virtual benefit happen."

A lot of the filming was done at the Nile.

"Michelle has a crew that's really adept and in tune with the technology side of it and making that happen," Martinez says. "We've definitely faced a lot of challenges going through the process and adapted to them. So it's been a fun learning experience"

Martinez was beyond impressed by the willingness of the artists he approached about sharing their talent and time to help his friend.

"Especially with the national artists, you ask with theideathat they'll probably say no," he says.

"They're either not gonna be available or it's just not gonna be their thing. But 95% of this lineup we envisioned said yes immediatelywithout question. It was pretty humbling and kind of a testament to Ryan's friendships that he forms."

These are friendships Butler started forming while still in his formative years at Arcadia High School, having hit the road hisjunior year with Lyburnum, a screamo band.

From there, he started Wellington, a doom-metal trio that released one album and a handful of EPs.

His next group, Unruh, toured the hardcore circuit in the States and Europe and released two albums and some EPs before breaking up.

After a brief stint in Structure of Lies, he was invited to joinNorth Side Kings as they were gearing up to tour with H2O and Madball, joining Landmine Marathon, whose debut album he'd recorded in his studio, Arcane Digital Recording, in 2006.

He spent the next 10 years in Landmine Marathon, which did more touring and recording than those other groups, while still playing in North Side Kings.

Butler hasn't done much playing since Landmine ended in late 2015. There's been a North Side Kings reunion show and that ill-fated Broloaf show with the trash can.

This past spring, he says, "Mobility was becoming an issue. By summer I was completely on a cane and not really getting around much at all. Plus the coronavirus. I couldn't be around that at all with my immunocompromised condition."

Playing in bands isa side of his life he's missed these past few years.

"When Landmine stopped, I had been touring and playing in multiple bands for so long, I was like, 'I need a break,'" he recalls.

"So I didn't pick up anything. And North Side Kings talked about playing more after that reunion. But my dad passed away and I had to deal with all kinds of stuff. So we never ended up playing any more shows. AndI got really sick shortly after that."

Being laid up in the hospital and even now that he's back home recovering has given Butler lots of time to think.

"The second I came out of the transplant a month ago, I felt awful because of the surgery, but Iknew instantly that my symptoms were gone," he says.

"So to be sitting there with nothing but time on your hands, you just start thinking about the future. And I'm definitely gonna be tuning up those guitars soon."

Here's a look at which companies are raking in cash this week in the biopharma industry.

Apollomics, Inc.

Committed tocombatting cancer with precision,Apollomics plans to use the$124.2 million Series Cfinancing to focusclinicalefforts on its lead programs: APL-101 and APL-106. APL-101 is an oral c-MET inhibitorcurrently involved in several ongoing clinical trials. TheSPARTA trialis in Phase II, targeting non-small cell lung cancer,glioblastomamultiforme and solid tumors with MET amplifications.APL-106 is a first-in-class targeted inhibitordesignedtoblockE-selectin, an adhesion molecule on cells in bone marrow,from binding with blood cancer cells.It has received Breakthrough Therapy Designation from the FDA in relapsed and refractory acute myeloid leukemia.In 2019,Apollomicsraised$100 million in a Series B round.

Decibel Therapeutics

Decibel Therapeutics made some noise this week with an oversubscribed Series D financing, raking in$82.2 million. The company will use the funds to advance DB-OTO, a gene therapy to restore hearing in children with congenital deafness due to a deficiency in the otoferlin gene.Clinical testing is expected to initiate in2022.DB-020 is already in a phase Ib study with cancer patients as apreventative treatment for the ototoxicityassociated with cisplatin-based chemotherapy.Hearing and balance disorders have historically been overlooked by the biopharma industry, even though they exact a devastating toll on the lives of hundreds of millions of people around the globe. At Decibel, we are dedicated to restoring hearing and balance with precision therapeutics designed to deliver the right genetic medicine specifically to the right cells in the ear, said Laurence Reid, Ph.D., Chief Executive Officer of Decibel.

Adagio Therapeutics

After launchingin Junewith $50 million, Adagio has pocketed another$80 million in a Series Bfinancing round to take its COVID-19 antibody into the clinic next year. Adagios neutralizing monoclonal antibodies are expected to provide broad protection against not onlyagainst SARS-CoV-2 and SARS-CoV-1, but also additional bat coronaviruses that have yet to cross the species barrier. Adagio got the green light from the FDA to proceed with their first-in-human study in early 2021.We were impressed by the thoughtful approach that Adagio took. By dealing with the broader coronavirus problem, we expect ADG20 to be more resistant to escape mutations and potentially cover future coronavirus pandemics, said Krishna Yeshwant, Managing Partner at GV. As a preventative agent, ADG20 holds the promise of providing the efficacy necessary to deliver greater protection against COVID-19. Given its unique combination of attributes, ADG20 could complement and supplement vaccines by providing rapid, durable antibody protection against current and future coronaviruses.

Passage Bio Highlights University of Pennsylvania’s Gene Therapy Program’s Newly Published Research to Prevent Toxicity Associated with Gene Therapy -…

PHILADELPHIA, Nov. 11, 2020 (GLOBE NEWSWIRE) -- Passage Bio Inc. (Nasdaq: PASG), a genetic medicines company focused on developing transformative therapies for rare, monogenic central nervous system (CNS) disorders, today commends the newly published research of the University of Pennsylvanias (Penn) Gene Therapy Program (GTP) regarding a novel targeted approach to prevent a selective neurotoxicity seen in the sensory neurons of dorsal root ganglia (DRG) after gene therapy treatment. As previously published, this DRG toxicity has been observed after both systemic and central nervous system (CNS) delivery of gene therapy and across a variety of vectors in pre-clinical models, but clinical manifestations have not been observed.1

As part of its unique collaboration agreement with Penn, Passage Bio has certain rights to this novel DRG technology for the indications the company progresses with Penn.

Although our safety studies for our programs have not shown any clinical manifestations of DRG toxicity, we are excited about the promising approach developed by Penns GTP, said Bruce Goldsmith, Ph.D., president and chief executive officer of Passage Bio. As part of our mission to develop transformative therapies for patients, we remain committed to advancing the field of gene therapy. If in the future this new approach shows clinical benefit for patients, we will be in a strong position to incorporate it into our programs. Our relationship with Penns GTP is an important distinguishing characteristic of Passage Bio. Through our collaboration, we have ready access to world-class expertise and groundbreaking research that we can rapidly apply, if appropriate, to our therapeutic programs.

GTPs research on preventing DRG toxicity published online this week in Science Translational Medicine. According to the researchers, DRG toxicity is the result of over expression of an introduced gene, known as a transgene, in cells in the DRG, a cluster of neural cells on the outside of the spinal cord responsible for transmission of sensory messages. To correct this over expression, the GTP research team modified a transgene with a microRNA target designed to reduce the level of the transgene expression in DRG neurons as well as toxicity in DRG neurons, without affecting transduction elsewhere in the brain. That alteration eliminated more than 80 percent of the transgene expression in DRG neurons and reduced the related DRG toxicity in preclinical studies with primates.

James M. Wilson, M.D., Ph.D., director of Penns GTP and a chief scientific advisor at Passage Bio, served as a senior author of the published manuscript. Juliette Hordeaux, DVM, Ph.D., senior director of Translational Research in Penns GTP is first author. They reported that their microRNA target approach may be a straightforward way to potentially make AAV therapy for the central nervous system more safe.

As previously reported, results from preclinical toxicology studies for Passage Bios lead therapeutic programs, PBGM01 (GM1 gangliosidosis), PBKR03 (Krabbe disease), PBFT02 (FTD-GRN), were consistent with this overall AAV platform observation, and showed no clinical manifestations in detailed neurological examinations or daily observations. To proactively determine whether there is appearance of clinical signs of DRG toxicity in our clinical programs, Passage Bio will implement monitoring of patients, consisting of both nerve-conduction studies and neurological exams focused on sensory and peripheral nerve functions.

Passage Bio is advancing six programs, which include the lead programs for GM1 gangliosidosis (GM1), Krabbe disease, and frontotemporal dementia (FTD), as well as three additional programs for amyotrophic lateral sclerosis (ALS), metachromatic leukodystrophy (MLD) and Charcot-Marie-Tooth disease Type 2a (CMT2a). The company anticipates that the initial three clinical candidates will be in clinical trials in 2021. Through its collaboration agreement with Penn, Passage Bio has the option to license a total of 17 programs focused on rare, monogenic disorders of the CNS.

About Passage Bio

At Passage Bio (Nasdaq: PASG), we are on a mission to provide life-transforming gene therapies for patients with rare, monogenic CNS diseases that replace their suffering with boundless possibility, all while building lasting relationships with the communities we serve. Based in Philadelphia, PA, our company has established a strategic collaboration and licensing agreement with the renowned University of Pennsylvanias Gene Therapy Program to conduct our discovery and IND-enabling preclinical work.
