Some discouraging news for the SMA community, as, according to the results of the CARNIVAL clinical trial, Valproic acid, also known as VPA, combined with L-carnitine does not improve the survival of SMA type I patients Previous studies suggested that VPA is a potential therapeutic candidate for SMA. In the CARNIVAL Type I trial, researchers led by Boston's Massachusetts General Hospital set out to investigate the safety and therapeutic potential of VPA, combined with L-carnitine, in infants with SMA. L-carnitine is a compound involved in cellular energy production. The Phase 2 study enrolled 37 infants with SMA type I aged two weeks to 12 months from seven clinics in the United States and Canada, and one in Germany. Cure SMA and Cure SMA Canada funded the study for the North American sites. Patients completed two screening visits within a two-week period to establish disease parameters at baseline. The babies then received two daily doses of L-carnitine and VPA. Researchers measured treatment effects at three and six months and compared them to an untreated, matched disease group of 57 type I infants. They chose controls retrospectively from a larger cohort of 151 SMA type I infants enrolled in the  University of Utah's Project Cure SMA database. The study's primary endpoint was to determine the treatment's safety and adverse effects. Secondary endpoints included survival, time to death or ventilator dependence, defined as more than 16 hours of ventilator support per day. Researchers detected 245 adverse effects, mostly related to respiratory problems, in 95 percent of patients. These resulted in 14 deaths. Overall, the CARNIVAL Type I trial proves no survival benefit for infants with SMA type I treated with L-carnitine/VPA.

Spotlight Innovation has entered into a sponsored research agreement with Indiana University to develop safe and effective therapeutic options for the treatment of spinal muscular atrophy. The partnership will seek to continue development of STL-182, the company’s lead product candidate for treating SMA. STL-182 is an orally-available small molecule that has been shown to have potential therapeutic effect in the treatment of SMA. Spotlight has previously reported that STL-182 has shown the potential in SMA mouse models to restore neuromuscular function by stabilizing such SMN protein levels. Dr. Elliot Androphy, inventor of the therapy, is also the chair of the Department of Dermatology of Indiana University School of Medicine. At Indiana, Androphy has used a novel, cell-based high throughput screen for compounds that increase SMN protein levels – work that has led to the identification of pre-clinical drug candidates for SMA.

According to a new study, a molecule known as A15/283 being developed to treat SMA , has shown significant efficacy in male mouse models of the disease. A15/283 is a DNA sequence that binds to mRNAs, which are the intermediary molecules between the DNA and the protein. Since mRNAs must be single-stranded in order to become “translated” into proteins, the binding of this DNA sequence to mRNA molecules renders the mRNA unable to be turned into a protein, as the molecule is now double-stranded. Using this technique against a degradation protein that would otherwise degrade SMN will likely boost SMN levels. Researchers gave A15/283 to mouse models of SMA lacking the SMN protein once and again three days after birth. Results showed gender-specific improvement of tail necrosis in male mice. Researchers also observed a modest increase in SMN protein levels, leading to significant improvement in certain symptoms specific to SMA in mice. Researchers also concluded that early administration of A15/283 led to a near-total correction in expression levels due to increases in the SMN protein. “These results in the mouse model are very promising for the possible treatment of mild spinal muscular atrophy cases in children,” Dr. Ravindra Singh, a professor of biomedical sciences at Iowa State's College of Veterinary Medicine, said in a press release. “We’re hoping this line of research could someday lead to clinical trials, but more work remains before that can happen.”

At nine months of age, Brianna Albers was diagnosed with spinal muscular atrophy (SMA) type 2. As a 22-year-old college senior from Rosemount, Minnesota, she also struggles with social anxiety, dysthymia (mild depression), and disordered sleep. In society’s view, she says, that makes her a bit of a monster. “Disabled…

Alyssa Silva was 8 years old when she set up a lemonade stand one summer day and saved the proceeds to benefit spinal muscular atrophy, which she had been diagnosed with at 5 months old. Although modest, her lemonade sales set the tone for years to come – she had been bitten by the fundraising bug. Now, at age 26, Silva’s nonprofit business WOW (Working on Walking) is holding a major fundraiser on Saturday, Aug. 26, in Providence, Rhode Island. This gala is different than the others and especially dear to Silva. It celebrates the first year that Biogen’s Spinraza, the first approved treatment for SMA, has been on the market. Spinraza was authorized in December 2016, which is when Silva began treatment. At the time she was in the middle of a clinical trial and the commercialization of the new drug. Biogen is the major sponsor of Saturday’s gala. “It’s a brand-new event this year. It’s both terrifying and exciting at the same time,” said Silva, who lives in nearby Cumberland with her parents. She said 100 percent of the proceeds will benefit SMA. They will be split between Cure SMA and Boston Children’s Hospital, which has an SMA clinic that distributes Spinraza. “The SMA clinic at Boston Children’s needs the money for research – they don’t get a lot from the hospital, so we give money to them,” Silva said. Tickets to the gala are $85, more than for any event WOW has held before. There will be food stations, a band, dancing, silent auctions and raffles. The wheelchair-bound young woman writes a blog called AlyssaKSilva.com, a column for SMA News Today called “Life, One Cup at a Time,” and graduated from college in 2013 with a business degree in marketing. She hopes to be a writer some day, though she doubts she’ll ever stop raising money for SMA. “It’s my joy, my passion project, but I don’t see it as the main component of my future,” she said. One year, 500 people attended the golf and dinner fundraiser. The annual WOW event generated $37,000 one year. In 2014 Silva decided to obtain nonprofit certification for WOW. Regarding the breakthrough SMA drug, Silva said Spinraza has improved her speech, respiratory function, and stamina. Although she classifies the changes as less than sweeping, the therapy "has made a big difference in my life,” she said. Her family has been her strength through the difficulties she's endured with SMA, Silva said. Her parents and big brother Adam, who is married and lives down the street, have been instrumental in helping her stay optimistic about her future, she said.

Spinal muscular atrophy (SMA) experts and patient representatives concede they have a long way to go in updating a consensus document on SMA standards of care. Their report, “218th ENMC International Workshop: Revisiting the consensus on standards of care in SMA, Naarden, The Netherlands, 19-21 February 2016,” recently appeared in the…

As potentially lifesaving, but costly, therapies become available for rare genetic diseases — such as Spinraza (nusinersen) for spinal muscular atrophy (SMA) — neurologists are finding themselves in the increasingly uncomfortable position of deciding which patients are most likely to benefit, and how they can help families pay for…
