IMLYGIC is First Oncolytic Immunotherapy to Demonstrate Therapeutic Benefit for Patients With Advanced Melanoma
IMLYGIC, administered via intralesional injection, is designed to cause the death of tumor cells and to initiate an anti-tumor immune response.
"We are pleased that IMLYGIC has received a positive opinion from the CHMP, and if approved by the
The positive CHMP opinion was based on a global, randomized, open-label Phase 3 trial evaluating the safety and efficacy of IMLYGIC in patients with Stage IIIB, IIIC or IV melanoma when resection was not recommended compared to granulocyte-macrophage colony-stimulating factor (GM-CSF). In the 436-patient study, IMLYGIC significantly improved durable response rate (DRR), the primary endpoint of the trial, in the intent-to-treat population. DRR is defined as the percent of patients with complete response (CR) or partial response (PR) maintained continuously for a minimum of six months. A key secondary endpoint was overall survival (OS). The positive CHMP opinion reflects subgroup analyses where the effect on OS was largest in patients with unresectable melanoma that has not spread beyond the skin or lymph nodes.
The most commonly reported treatment-related adverse events were fatigue, chills, pyrexia, nausea, influenza-like illness and injection-site pain. Overall, 98 percent of these adverse reactions reported were mild or moderate in severity. The most common grade 3 or higher adverse reaction was cellulitis.
Melanoma is a type of skin cancer that is characterized by the uncontrolled growth of melanocytes, which are the cells responsible for providing the pigment to skin.1 Melanoma is the most aggressive and serious form of skin cancer, and remains a significant public health concern in the
Following this CHMP opinion,
About IMLYGIC (talimogene laherparepvec) in the EU
IMLYGIC is an oncolytic immunotherapy that is derived from HSV-1, which is commonly called the cold sore virus. IMLYGIC has been modified to replicate within tumors and to produce the immune stimulatory protein human GM-CSF. IMLYGIC causes the death of tumor cells and the release of tumor-derived antigens. It is thought that, together with GM-CSF, it will promote a systemic anti-tumor immune response and an effector T cell response.
About IMLYGIC (talimogene laherparepvec) in the U.S.
IMLYGIC is a genetically modified herpes simplex type 1 virus that is injected directly into tumors. IMLYGIC replicates inside tumor cells and produces GM-CSF, an immunostimulatory protein. IMLYGIC then causes the cell to rupture and die in a process called lysis. The rupture of the cancer cells causes the release of tumor-derived antigens, which together with virally derived GM-CSF may help to promote an anti-tumor immune response. However, the exact mechanism of action is unknown.

This news release contains forward-looking statements that are based on the current expectations and beliefs of
No forward-looking statement can be guaranteed and actual results may differ materially from those we project. Discovery or identification of new product candidates or development of new indications for existing products cannot be guaranteed and movement from concept to product is uncertain; consequently, there can be no guarantee that any particular product candidate or development of a new indication for an existing product will be successful and become a commercial product. Further, preclinical results do not guarantee safe and effective performance of product candidates in humans. The complexity of the human body cannot be perfectly, or sometimes, even adequately modeled by computer or cell culture systems or animal models. The length of time that it takes for us and our partners to complete clinical trials and obtain regulatory approval for product marketing has in the past varied and we expect similar variability in the future. We develop product candidates internally and through licensing collaborations, partnerships and joint ventures. Product candidates that are derived from relationships may be subject to disputes between the parties or may prove to be not as effective or as safe as we may have believed at the time of entering into such relationship. Also, we or others could identify safety, side effects or manufacturing problems with our products after they are on the market. Our business may be impacted by government investigations, litigation and product liability claims. If we fail to meet the compliance obligations in the corporate integrity agreement between us and the U.S. government, we could become subject to significant sanctions. We depend on third parties for a significant portion of our manufacturing capacity for the supply of certain of our current and future products and limits on supply may constrain sales of certain of our current products and product candidate development.
In addition, sales of our products (including products of our wholly-owned subsidiaries) are affected by the reimbursement policies imposed by third-party payers, including governments, private insurance plans and managed care providers and may be affected by regulatory, clinical and guideline developments and domestic and international trends toward managed care and healthcare cost containment as well as U.S. legislation affecting pharmaceutical pricing and reimbursement. Government and others' regulations and reimbursement policies may affect the development, usage and pricing of our products. In addition, we compete with other companies with respect to some of our marketed products as well as for the discovery and development of new products. We believe that some of our newer products, product candidates or new indications for existing products, may face competition when and as they are approved and marketed. Our products may compete against products that have lower prices, established reimbursement, superior performance, are easier to administer, or that are otherwise competitive with our products. In addition, while
