New insights into antiviral gene could help combat many diseases including Zika

A gene called RSAD2 is well-known among scientists who study virology, because it codes for an enzyme that stops several viruses from replicating. Now, researchers at Albert Einstein College of Medicine and Pennsylvania State University have gained new insight into RSAD2 that they believe could be used to create new antiviral therapies.The enzyme that RSAD2 makes is called viperin, and it naturally creates a compound that stops a range of viruses from replicating. That compound, called ddhCTP, inhibits a virus’s ability to copy its genetic material, the researchers reported in the journal Nature. They believe their discoveries could help in the design of new antiviral treatments inspired by ddhCTP, and they generated early evidence that such a molecule could be effective against three strains of Zika.

Heron Therapeutics Announces FDA Approval of ZYNRELEF® Indication Expansion to Include Additional Orthopedic and Soft Tissue Procedures

Heron Therapeutics, Inc. | January 29, 2024

Heron Therapeutics, Inc. a commercial-stage biotechnology company announced that the U.S. Food and Drug Administration (the "FDA") has approved its supplemental New Drug Application ("NDA") for ZYNRELEF® extended-release solution to expand the indication for soft tissue and orthopedic surgical procedures including foot and ankle, and other procedures in which direct exposure to articular cartilage is avoided. ZYNRELEF was previously approved for foot and ankle, small-to-medium open abdominal, and lower extremity total joint arthroplasty surgical procedures in adults. This expanded indication for ZYNRELEF will now cover an estimated 13 million procedures annually, an estimated increase of 86% over prior indicated procedures. To obtain this labeling expansion, Heron successfully conducted studies for cesarean section, spinal surgery, augmentation mammoplasty, and total shoulder arthroplasty. No unique safety issues were identified from the new clinical trials, and the bupivacaine and meloxicam blood concentrations were consistent with previous experience following ZYNRELEF administration. "The expanded indication is poised to have a transformative impact on patient care, providing healthcare professionals with a versatile and effective solution for managing postoperative pain across an even wider range of surgical procedures. The new label expansion and recent partnership with CrossLink, combined with the potential approval of the Vial Access Needle ("VAN") later this year, are expected to have a significant positive impact for ZYNRELEF and the Company," said Craig Collard, Chief Executive Officer of Heron. "We're excited for the opportunity to give even more healthcare providers and patients a new, safe and effective option for achieving long-lasting non-opioid pain control after painful surgical procedures," said Bill Forbes, Executive Vice President, Chief Development Officer at Heron. "This new approval further reinforces our commitment to providing meaningful solutions to address unmet medical needs in the acute care and oncology settings." ZYNRELEF is the first and only therapy for postoperative pain management to be rigorously tested in Phase 3 studies and demonstrate superiority to bupivacaine solution, the current standard-of-care. ZYNRELEF demonstrated superiority compared to bupivacaine with lower pain scores, fewer patients experiencing severe pain, and lower opioid consumption. ZYNRELEF was initially approved by the FDA in May 2021 and received approval of the first supplemental NDA for an expanded label in December 2021. "Patients undergoing orthopedic procedures often experience severe pain, slowing down their recovery time and potentially leading to other complications. Reducing patients' pain within the first three days is critical for patient satisfaction, and having a product like ZYNRELEF now available for additional orthopedic procedures is a great benefit to have in my practice," said Alexander Sah, M.D., orthopedic surgeon at Sah Orthopaedic Associates. "ZYNRELEF helps my patients recover fully, be discharged sooner, and have significantly less pain, with little to no opioid use." Important Safety Information for Patients ZYNRELEF contains an NSAID (non-steroidal anti-inflammatory drug), a type of medicine which Can increase the risk of a heart attack or stroke that can lead to death. This risk increases with higher doses and longer use of an NSAID. Cannot be used during heart bypass surgery. Can increase the risk of gastrointestinal bleeding, ulcers, and tears. ZYNRELEF should also not be used if you are allergic to any component of ZYNRELEF, similar local anesthetics, aspirin or other NSAIDs (such as ibuprofen or naproxen), or have had an asthma attack, hives, or other allergic reaction after taking any of these medicines. as a paracervical block, during childbirth. The most common side effects of ZYNRELEF are soft tissue procedures: vomiting and orthopedic procedures: constipation and headache. The medicines in ZYNRELEF (a local anesthetic and an NSAID) may affect the nervous and cardiovascular system; may cause liver or kidney problems; may reduce the effects of some blood pressure medicines; should be avoided if you have severe heart failure; may cause adverse effects on cartilage; may cause a rare blood disorder, or life-threatening skin or allergic reactions; may harm your unborn baby if received at 20 weeks of pregnancy or later; and may cause low red blood cells (anemia). Tell your healthcare provider about all your medical conditions and about all the medicines you take including prescription or over-the-counter medicines, vitamins, or herbal supplements to discuss if ZYNRELEF is right for you.
