Merck’s Mavenclad (cladribine tablets) is now a recommended treatment for British adults with highly active multiple sclerosis (MS), following the issuance of a final appraisal determination by the country’s National Institute for Health and Clinical Excellence (NICE). The therapy — given at a dosage of 10 mg — received the…

Sanofi Genzyme and Principia Biopharma have entered into a license agreement to advance the clinical development of PRN2246, an oral drug candidate for the treatment of multiple sclerosis and other diseases of the central nervous system. PRN2246 is an inhibitor of the Bruton’s tyrosine kinase, an enzyme encoded by the BTK gene that plays a crucial role in B-cell development and the B-cell signaling pathway. B-cells are known to be involved in the development of autoimmune diseases that affect the nervous system, including multiple sclerosis. PRN2246 is an orally available therapy designed to easily access the central nervous system (brain and spinal cord) by crossing the blood-brain barrier, and impact the signaling of immune cells and brain cells involved in autoimmunity and inflammatory processes. The drug is designed to safely and effectively modulate B-cell function without depleting these cells. A Phase 1 clinical trial is now testing the drug's safety in healthy volunteers. Under the agreement, which is expected to close shortly, Principia will grant Sanofi an exclusive, worldwide license to develop and commercialize PRN2246. Principia, in return, will receive $40 million in upfront payments from Sanofi, and future milestone payments could reach $765 million. Principia will retain the option to co-fund the treatment's Phase 3 development in exchange for other royalties in the United States. Principia has developed a novel way to design and develop better and safer therapies based on oral small molecules. The company uses its proprietary Tailored Covalency technology to develop its drug candidates, which are, according to the company's website, safer, and more selective, potent and durable than other available treatments. The terms of this licensing agreement are still subject to customary regulatory approval.

Do you have pain? Although prone to subjectivity, I am certain the majority of you silently said yes. I did. I hesitated to write this, as pain, from the definition of it to the management of it, is idiosyncratic. Rather than draw hard and fast lines, I prefer to…

Editor’s note: This is the second of a two-part series on readers’ comments about Ocrevus (ocrelizumab). Read part one here. Last week, I responded to a few comments on columns regarding my personal experience with Ocrevus (ocrelizumab). Here are more reader comments and my answers.

Have you ever thought about stopping whatever MS treatment you’re using? I have. So has John Corboy. Corboy’s not an MS patient. Rather, he’s a researcher at the University of Colorado’s medical school. And he’s studying whether older patients, if they haven’t had a relapse for several…

The National Multiple Sclerosis Society (NMSS) has officially announced its collaboration with Corrona on the launch of the Corrona Multiple Sclerosis Registry to compare the safety and effectiveness of approved therapies in multiple sclerosis (MS). Corrona, based in Cambridge, Massachusetts, conducts observational cohort studies, offering analytic expertise…

RedHill Biopharma has received a Notice of Allowance for a new patent on RHB-104 its potential therapy for patients with relapsing-remitting multiple sclerosis (RRMS). Once granted by the United States Patent and Trademark Office (USPTO), this patent will be valid until 2032. RHB-104 is a proprietary, orally-administered antibiotic combination with potentially potent intracellular, antimycobacterial…

Editor’s Note: First in a two-part series on readers’ comments about Ocrevus (ocrelizumab). I switched disease-modifying therapies and began treatment with Ocrevus (ocrelizumab) in June. I previously wrote about my reasons for switching, my experiences with the first two doses, and more recently, about any…

Researchers, using two different kinds of stem cells in rats, were able to regenerate oligodendrocytes — myelin-producing brain cells that are defective in multiple sclerosis (MS). They were also able to grow adult neural stem cells in laboratory cultures and prod them to develop into oligodendrocytes. The exact cause of MS is unknown — including what triggers attacks on myelin — but the loss of oligodendrocytes seen in the disease is known to play a role in its progression. Nerve cells in the brain send their signals through their axons, long arm-like structures that extend out from the centers of the nerve cells. The signals are electrical pulses transmitted along the length of an axon. Oligodendrocytes provide the insulation — called myelin — that wraps around axons, speeding up the transmission of electrical signals through the nerve cells. Loss or malfunction of oligodendrocytes means that signaling in the brain is impaired. It is this slowing of signaling that is thought to cause MS symptoms. Researchers from the Heinrich-Heine-University, Germany, with support from British and Chilean colleagues, designed a novel approach to regenerate oligodendrocytes, according to a press release. Stem cells are immature cells that give rise to differentiated cells — cells with a specific function, such as oligodendrocytes. Adult neural stem cells can divide and produce nerve cells and other brain cells, including oligodendrocytes. However, in normal circumstances, the regeneration of cells that take place in the human brain is not enough to repair the damage seen in MS. The researchers set out to find conditions that would promote the differentiation of adult human NSCs into oligodendrocytes. They discovered that another type of stem cell, mesenchymal stem cells (MSCs), could provide the signals required. First they tested their system in rats, and found that by using factors produced by human MSCs, they could induce the growth of new oligodendrocytes in the animals. Then they grew adult NSCs in the laboratory, and using the same factors from human MSCs were able to promote the establishment of oligodendrocytes in the cultured cells.

Preliminary data from the Phase 3 EVOLVE-MS-1 trial shows that ALKS 8700 — an investigative therapy developed by Alkermes to treat relapsing forms of multiple sclerosis — has a good safety and tolerability profile. ALKS 8700 is an oral compound. Once inside the body, it is rapidly transformed into the therapeutic compound monomethyl fumarate (MMF). Although similar, this drug candidate was designed to offer features different than those achieved with the commercially available Tecfidera (dimethyl fumarate). Alkermes is currently assessing the safety and efficacy of ALKS 8700 in the EVOLVE-MS program, which includes two Phase 3 clinical trials in patients with relapsing-remitting MS. The EVOLVE-MS-1 is a two-year study being conducted in 107 U.S. and European research sites. It will evaluate the long-term safety of ALKS 8700 in some 930 RRMS patients. Interim data collected during the first month of treating 580 participants showed low incidence of GI adverse events, with no reports of serious events. The most common adverse side effects associated with the treatment were flushing, pruritus and diarrhea. Alkermes, which is based in Ireland, said additional results from the initial three months of treatment further supported the positive safety data of ALKS 8700, with only 2.3 percent of patients reporting serious adverse events and 3.7 percent having to stop treatment. The EVOLVE-MS-2 trial, being conducted at 48 U.S. sites, will compare the safety and efficacy of ALKS 8700 versus Tecfidera in RRMS patients. The study is still recruiting participants. Recent data of EVOLVE-MS-2 was also subject of a poster presentation at the ECTRIMS-ACTRIMS Meeting.

Gilenya (fingolimod) was seen to significantly reduce relapses in children and teenagers with multiple sclerosis (MS), according to data from a Phase 3 study — the first successfully conducted in pediatric patients. Novartis, the therapy’s developer, is preparing to file requests for Gilenya to be approved to…
