Talimogene laherparepvec

Antineoplastic Agents, Immunological

Talimogene laherparepvec was administered by intralesional injection into injectable cutaneous, subcutaneous, and nodal lesions at an initial dose of 10⁶ plaque-forming units (PFU) per mL on day 1 followed by a dose of 10⁸ PFU/mL 21 days after the initial dose and every 14 days thereafter. Participants were treated with talimogene laherparepvec until they achieved a complete response, all injectable tumors had disappeared, clinically significant (resulting in clinical deterioration or requiring change of therapy) disease progression beyond 6 months of treatment, per modified World Health Organization (WHO) response criteria, or intolerance of study treatment, whichever occurred first.

The initial dose of talimogene laherparepvec is up to 4.0 mL of 10\^6 PFU/mL. Subsequent doses of talimogene laherparepvec are up to 4.0 mL of 10\^8 PFU/mL.

Talimogene Laherparepvec

The study is a phase 2, multi centered, single arm study designed to evaluate the correlation between cluster of differentiation 8-positive (CD8+) cell density and objective response rate in adults with unresected stage IIIB to IVM1c melanoma. This study will also evaluate the safety and tolerability profile of talimogene laherparepvec.

The study will explore the hypothesis that intratumoral CD8+ cell density at baseline correlates with objective response rate in adults with unresected stage IIIB to IVMIc melanoma treated with talimogene laherparepvec.

A univariate logistic regression model was performed to evaluate baseline log2(CD8+ cell density) as a predictor of objective response.

Response was assessed according to the modified version of the World Health Organization (WHO) response criteria. Objective response rate (ORR) was defined as the percentage of participants with a complete response (CR) or partial response (PR) according to the modified WHO criteria.

The unadjusted odds ratio of log2(baseline intratumoral CD8+ cell density) for objective response rate is reported.

A univariate logistic regression model was performed to evaluate baseline log2(CD8+ cell density) as a predictor of durable response.

Response was assessed according to the modified version of the World Health Organization (WHO) response criteria. Durable response rate (DRR) was defined as the percentage of participants with an objective response lasting continuously for 6 months and starting any time within 12 months of initiating therapy.

The unadjusted odds ratio of log2(baseline intratumoral CD8+ cell density) for durable response rate is reported.

Primary completion is defined as PC and final analysis is defined as FA.

A Cox proportional hazards regression model was performed to evaluate baseline log2(CD8+ cell density) as a predictor of duration of response.

Response was assessed according to the modified version of the World Health Organization (WHO) response criteria. Duration of response (DOR) is defined as the longest individual period from entering an objective response (CR/PR) to the first documented evidence of the participant no longer meeting the criteria for being in the response (i.e. an overall response of either stable disease \[SD\] as compared with baseline or progressive disease \[PD\]).

The unadjusted hazard ratio of log2(baseline intratumoral CD8+ cell density) for duration of response is reported.

Pearson's correlation coefficient (r) was estimated to assess the relationship between baseline log2(CD8+ cell density) and the maximum decrease in measurable tumor burden.

Tumor burden is the sum of the products of the 2 largest perpendicular diameters (SPD) for all index lesions selected at baseline.

The Pearson's correlation coefficient (r) of log2(baseline intratumoral CD8+ cell density) and the maximum decrease in tumor burden is reported.

Primary completion is defined as PC and final analysis is defined as FA.

A univariate logistic regression model was performed to evaluate change from baseline to week 6 in log2(CD8+ cell density) in uninjected tumors as a predictor of objective response.

Response was assessed according to the modified version of the World Health Organization (WHO) response criteria. Objective response rate (ORR) was defined as the percentage of participants with a complete response or partial response according to the modified WHO criteria.

The unadjusted odds ratio of log2(change from baseline intratumoral CD8+ cell density) for objective response rate is reported.

Intratumoral CD8+ Cell density has been shortened to "CD8+ cell density" in the time frame due to character limit. Primary completion is defined as PC and final analysis is defined as FA.

Objective Response rate is defined as the percentage of participants with either a CR or PR based on Modified WHO Response Criteria.

CR: Complete disappearance of all index lesions, all non-index lesions, and any new tumors which might have appeared. Any residual cutaneous or subcutaneous index lesions must be documented by representative biopsy to not contain viable tumor.

PR: Disappearance of all index lesions with persistence of one or more non-index tumor(s), or, 50% or greater reduction in the 2 largest perpendicular diameters (SPD) of all index lesions as compared to baseline, and disappearance or persistence of non-index lesions.

Duration of response (DOR) was defined as the longest individual period from entering an objective response (CR/PR) to the first documented evidence of the participant no longer meeting the criteria for objective response (i.e. an overall response of either stable disease \[SD\] as compared with baseline or progressive disease \[PD\]).

SD: Neither sufficient tumor shrinkage of index lesion to qualify for response (PR or CR) nor sufficient tumor increase of index lesion to qualify for PD, with no increase in size of non-index lesions.

PD: A \> 25% increase in the sum of the SPD of all index tumors since baseline, or the unequivocal appearance of a new tumor since the last response assessment time point, or unequivocal progression of one or more non-index lesions.

Participants last reported to be either a CR or PR were censored at that time point.

Time to treatment failure (TTF) was calculated from first dosing until one or more of the following: (1) clinically relevant disease progression (PDr); (2) death from any cause; (3) non clinically relevant disease progression (PDn) associated with a requirement for alternative therapy as the reason for ending treatment or start of new anti-cancer therapy. Participants with no event were censored at their last evaluable tumor assessment.

Durable response rate (DRR) was defined as the percentage of participants with an objective response (CR or PR) based on modified WHO response criteria lasting continuously for 6 months and starting any time within 12 months of initiating therapy.

Overall survival (OS) was defined as the time from the date of first dose to the date of death from any cause.

OS time was censored at the last date the participant was known to be alive when the confirmation of death is absent or unknown.

Tumor burden is the sum of the products of the 2 largest perpendicular diameters (SPD) for all index lesions selected at baseline.

Change from baseline in tumor burden was assessed in participants with an objective response.

The severity of each adverse event (AE) was assessed according to the Common Terminology Criteria for Adverse Events (CTCAE), version 3.0 grading scale, where Grade 1 = Mild AE Grade 2 = Moderate AE Grade 3 = Severe AE Grade 4 = Life-threatening or disabling AE Grade 5 = Death related to AE Treatment-related adverse events (TRAE) were those assessed by the investigator as possibly related to talimogene laherparepvec.
