Study Details
Study Description
Brief Summary
The primary objectives of the Phase 1b part of the study are to evaluate the safety, as assessed by incidence of dose limiting toxicity (DLT), of talimogene laherparepvec in combination with pembrolizumab in adults with previously untreated, unresectable, stage IIIB to IVM1c melanoma.
The primary objective of Phase 3 are to evaluate the efficacy of talimogene laherparepvec with pembrolizumab versus placebo with pembrolizumab, as assessed by progression-free survival (PFS) (response evaluation by blinded independent central review using modified Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) and overall survival (OS).

A DLT was defined as any toxicity related to study drug which met any of the following criteria based on Common Terminology Criteria for Adverse Events (CTCAE) version 4.0: Grade 4 non-hematologic toxicity. Grade 3 or higher pneumonitis. Grade 3 non-hematologic toxicity lasting > 3 days despite optimal supportive care, excluding grade 3 fatigue. Any grade 3 or higher non-hematologic laboratory value if medical intervention was required, or the abnormality lead to hospitalization, or the abnormality persisted for > 1 week. Febrile neutropenia grade 3 or grade 4. Thrombocytopenia < 25 x 10^9/L if associated with a bleeding event which does not result in hemodynamic instability but required an elective platelet infusion, or a life-threatening bleeding event which resulted in urgent intervention and admission to intensive care unit. Grade 5 toxicity (ie, death). Any other intolerable toxicity leading to permanent discontinuation of talimogene laherparepvec or pembrolizumab.

The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) is a 30-question tool used to assess the overall quality of life in cancer patients. It consists of 15 domains: 1 global health status/quality of life scale, 5 functional scales, and 9 symptom scales/items. The global health/QoL scale consists of 2 questions that ask participants to rate their overall health and overall quality of life during the past week on a scale from 1 (very poor) to 7 (excellent). The GHS/QoL subscale score was derived as the mean of each score then transformed to a scale from 0 to 100 where higher scores represent a better health status and a positive change from baseline indicates improvement. The overall change from baseline (calculated from all on-treatment visits) was calculated using a restricted maximum likelihood-based mixed model for repeated measures (MMRM) (see model details in statistical analysis section).
- Number of Participants With Treatment-emergent Adverse Events (TEAEs) [From first dose to 30 days after last dose (90 days for SAEs); median (range) duration was 48 (5.1, 110.1) weeks in Phase 1b, 39 (0.1, 107.3) weeks in Placebo + Pembrolizumab and 56 (0.1, 109.6) weeks in Phase 3 Talimogene Laherparepvec + Pembrolizumab.]
An adverse event (AE) is any untoward medical occurrence in a clinical trial subject, including worsening of a pre-existing medical condition. The event does not necessarily have a causal relationship with study treatment. TEAEs include AEs from the first dose of study drug to 30 days after the last dose. A serious adverse event (SAE) is an AE that met at least 1 of the following criteria: fatal life threatening required in-patient hospitalization or prolongation of existing hospitalization resulted in persistent or significant disability/incapacity congenital anomaly/birth defect other medically important serious event. Treatment-emergent SAEs are any SAE occurring from first dose of study drug through 90 days after the last dose or 30 days after the last dose if new anticancer therapy was started, whichever was earlier. AEs were graded for severity using CTCAE version 4.0, where Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Life-threatening; Grade 5 = Fatal.

Study Results
Participant Flow
Recruitment Details | This study was conducted at 134 centers in Australia, Canada, Europe, South Africa, South Korea, and the United States. Phase 1b was an open-label, single-arm study and Phase 3 was a randomized, double-blind, placebo-controlled study. |
---|---|
Pre-assignment Detail | In Phase 3 participants were randomized equally to 1 of 2 arms. Randomization was stratified by stage of disease: less advanced stages (IIIB, IIIC, and IVM1a) versus more advanced stages (IVM1b and IVM1c) and by prior serine/threonine protein kinase B-Raf (BRAF) inhibitor therapy (no prior BRAF inhibitor versus BRAF inhibitor with or without mitogen-activated extracellular signal-regulated kinase [MEK] inhibitor). |

---|---|---|---|
Arm/Group Description | Participants received talimogene laherparepvec at an initial dose of up to 4 mL 10⁶ plaque-forming units (PFU)/mL by intralesional injection on day 1 of week 1. Subsequent doses of talimogene laherparepvec at up to 4 mL of 10⁸ PFU/mL began 3 weeks after the first dose and were administered every 2 weeks until disappearance of injectable lesions, complete response (CR), confirmed disease progression (PD) per modified Immune-related Response Criteria (irRC), intolerance of study treatment, 24 months from the date of the first dose of pembrolizumab, or end of study, whichever occurred first. Participants also received 200 mg pembrolizumab administered intravenously every 2 weeks starting at the time of the third dose of talimogene laherparepvec (week 6) until confirmed PD per modified irRC, treatment intolerance, 24 months from the first dose, or end of study, whichever occurred first. | Participants received up to 4 mL placebo to talimogene laherparepvec by intralesional injection on day 1 of week 0. Subsequent doses of placebo (up to 4 mL) began 3 weeks after the first dose and were administered every 2 weeks until the fifth injection (week 9), and then synchronously with pembrolizumab thereafter every 3 weeks until disappearance of injectable lesions, complete response per modified Immune-related Response Criteria simulating Response Evaluation Criteria in Solid Tumors (irRC-RECIST) (iCR), confirmed iPD per modified irRC-RECIST, intolerance of study treatment, 24 months from the date of the first dose of placebo, or end of study, whichever occurred first.

Outcome Measures
Title | Phase 1b: Number of Participants With Dose-limiting Toxicities (DLTs) |
---|---|
Description | A DLT was defined as any toxicity related to study drug which met any of the following criteria based on Common Terminology Criteria for Adverse Events (CTCAE) version 4.0: Grade 4 non-hematologic toxicity. Grade 3 or higher pneumonitis. Grade 3 non-hematologic toxicity lasting > 3 days despite optimal supportive care, excluding grade 3 fatigue. Any grade 3 or higher non-hematologic laboratory value if medical intervention was required, or the abnormality lead to hospitalization, or the abnormality persisted for > 1 week. Febrile neutropenia grade 3 or grade 4. Thrombocytopenia < 25 x 10^9/L if associated with a bleeding event which does not result in hemodynamic instability but required an elective platelet infusion, or a life-threatening bleeding event which resulted in urgent intervention and admission to intensive care unit. Grade 5 toxicity (ie, death). Any other intolerable toxicity leading to permanent discontinuation of talimogene laherparepvec or pembrolizumab. |
Time Frame | The DLT evaluation period was 6 weeks from the initial administration of pembrolizumab (week 6 to 12). |
Outcome Measure Data
Analysis Population Description |
---|
The DLT analysis set included DLT-evaluable participants enrolled in Phase 1b who had the opportunity to be on treatment for at least 6 weeks from the initial dose of pembrolizumab and received at least 2 doses of talimogene laherparepvec and 2 doses of pembrolizumab in combination (ie, on the same day), or those who otherwise experienced a DLT within 6 weeks after starting the combination therapy. |
Arm/Group Title | Phase 1b: Talimogene Laherparepvec + Pembrolizumab |
---|---|
Arm/Group Description | Participants received talimogene laherparepvec at an initial dose of up to 4 mL 10⁶ plaque-forming units (PFU)/mL by intralesional injection on day 1 of week 1. Subsequent doses of talimogene laherparepvec at up to 4 mL of 10⁸ PFU/mL began 3 weeks after the first dose and were administered every 2 weeks until disappearance of injectable lesions, complete response (CR), confirmed disease progression (PD) per modified Immune-related Response Criteria (irRC), intolerance of study treatment, 24 months from the date of the first dose of pembrolizumab, or end of study, whichever occurred first. Participants also received 200 mg pembrolizumab administered intravenously every 2 weeks starting at the time of the third dose of talimogene laherparepvec (week 6) until confirmed PD per modified irRC, treatment intolerance, 24 months from the first dose, or end of study, whichever occurred first. |

Title | Phase 3: Progression Free Survival (PFS) by Blinded Independent Central Review (BICR) Assessed Using Modified RECIST 1.1 |
---|---|
Description | PFS per modified Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 is defined as the interval from randomization to the earlier event of progressive disease (PD) per modified RECIST 1.1 or death from any cause. PD: Increase in size of target lesions from nadir by ≥ 20% and ≥ 5 mm absolute increase above nadir, or the appearance of a new lesion. Median PFS was calculated using the Kaplan-Meier method.

Title | Phase 3: Change From Baseline in European Organisation for Research and Treatment of Cancer Quality of Life Core Module (EORTC QLQ-C30) Global Health Status (GHS)/Quality of Life (QOL) Score |
---|---|
Description | The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-C30 (EORTC QLQ-C30) is a 30-question tool used to assess the overall quality of life in cancer patients. It consists of 15 domains: 1 global health status/quality of life scale, 5 functional scales, and 9 symptom scales/items. The global health/QoL scale consists of 2 questions that ask participants to rate their overall health and overall quality of life during the past week on a scale from 1 (very poor) to 7 (excellent). The GHS/QoL subscale score was derived as the mean of each score then transformed to a scale from 0 to 100 where higher scores represent a better health status and a positive change from baseline indicates improvement. The overall change from baseline (calculated from all on-treatment visits) was calculated using a restricted maximum likelihood-based mixed model for repeated measures (MMRM) (see model details in statistical analysis section). |
Time Frame | Baseline and day 1 of weeks 3, 6, 9, 12, then every 6 weeks until end of study treatment; median (range) duration of treatment was 39.0 (0.1, 107.3) weeks in Placebo + Pembrolizumab and 54.1 (0.1, 109.6) weeks in Talimogene Laherparepvec + Pembrolizumab. |

Title | Number of Participants With Treatment-emergent Adverse Events (TEAEs) |
---|---|
Description | An adverse event (AE) is any untoward medical occurrence in a clinical trial subject, including worsening of a pre-existing medical condition. The event does not necessarily have a causal relationship with study treatment. TEAEs include AEs from the first dose of study drug to 30 days after the last dose. A serious adverse event (SAE) is an AE that met at least 1 of the following criteria: fatal life threatening required in-patient hospitalization or prolongation of existing hospitalization resulted in persistent or significant disability/incapacity congenital anomaly/birth defect other medically important serious event. Treatment-emergent SAEs are any SAE occurring from first dose of study drug through 90 days after the last dose or 30 days after the last dose if new anticancer therapy was started, whichever was earlier. AEs were graded for severity using CTCAE version 4.0, where Grade 1 = Mild; Grade 2 = Moderate; Grade 3 = Severe; Grade 4 = Life-threatening; Grade 5 = Fatal. |
Time Frame | From first dose to 30 days after last dose (90 days for SAEs); median (range) duration was 48 (5.1, 110.1) weeks in Phase 1b, 39 (0.1, 107.3) weeks in Placebo + Pembrolizumab and 56 (0.1, 109.6) weeks in Phase 3 Talimogene Laherparepvec + Pembrolizumab. |

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
The Clinical Trial Agreement generally does not restrict an investigator's discussion of trial results after completion. The Agreement permits Amgen a limited period of time to review material discussing trial results (typically up to 45 days and possible extension). Amgen may remove confidential information, but authors have final control and approval of publication content. For multicenter studies, the investigator agrees not to publish any results before the first multi-center publication.
