Imlygic should be administered by injection into cutaneous, subcutaneous, and/or nodal lesions that are visible, palpable, or detectable by ultrasound guidance.Imlygic is provided in single-use vials of 1 mL each in two different dose strengths: 10*6 (1 million) plaque-forming units (PFU) per mL (light green cap) – for initial dose only and 10*8 (100 million) PFU per mL (royal blue cap) – for all subsequent doses. The initial recommended dose is up to 4 mL at a concentration of 10*6 (1 million) PFU per mL. The recommended dose for subsequent administrations is up to 4 mL at a concentration of 10*8 (100 million) PFU per mL. Please see drug label for recommended dose schedule and dose volume determination.Clinical ResultsFDA ApprovalThe FDA approval of Imlygic was based on Study 005/05, referred to as OPTiM. OPTiM was a phase III, multicenter, open-label, randomized clinical trial comparing Imlygic to GM-CSF in 436 patients with advanced melanoma (Stage IIIB, IIIC, or IV) that was not surgically resectable. The subjects were randomized to receive either Imlygic (n = 295) or GM-CSF (n = 141). Imlygic was administered by intralesional injection at an initial concentration of 10*6 (1 million) PFU per mL on Day 1, followed by a concentration of 10*8 (100 million) PFU per mL on Day 21 and every 2 weeks thereafter, at a dose of up to 4 mL per visit. GM-CSF was administered subcutaneously in 28-day cycles, i.e., 125 µg/m2 daily for 14 days followed by 14 days without GM-CSF administration. The primary endpoint of the study was durable response rate (DRR), defined as the percent of patients with complete response (CR) or partial response (PR) maintained continuously for a minimum of six months. In the study, 16.3 percent of patients treated with Imlygic achieved a durable response compared to 2.1 percent of patients treated with GM-CSF (p <0.0001). Of the patients who experienced a durable response, 29.1 percent had a durable CR and 70.8 percent had a durable PR. In the study, the median time to response was 4.1 (range: 1.2 to 16.7) months in the Imlygic arm.Side EffectsAdverse effects associated with the use of Imlygic may include, but are not limited to, the following:•fatigue•chills•pyrexia•nausea•influenza-like illness•injection site painMechanism of ActionImlygic (talimogene laherparepvec) is a genetically modified oncolytic viral therapy. It was designed to replicate within tumors and to produce the immune stimulatory protein GM-CSF. Imlygic causes lysis of tumors, followed by release of tumor-derived antigens, which together with virally derived GM-CSF may promote an antitumor immune response.
