Oncolytic Immunotherapy

Purpose Talimogene laherparepvec (T-VEC) is a herpes simplex virus type 1–derived oncolytic immunotherapy designed to selectively replicate within tumors and produce granulocyte macrophage colony-stimulating factor (GM-CSF) to enhance systemic antitumor immune responses. T-VEC was compared with GM-CSF in patients with unresected stage IIIB to IV melanoma in a randomized open-label phase III trial. Patients and Methods Patients with injectable melanoma that was not surgically resectable were randomly assigned at a two-to-one ratio to intralesional T-VEC or subcutaneous GM-CSF. The primary end point was durable response rate (DRR; objective response lasting continuously ≥ 6 months) per independent assessment. Key secondary end points included overall survival (OS) and overall response rate. Results Among 436 patients randomly assigned, DRR was significantly higher with T-VEC (16.3%; 95% CI, 12.1% to 20.5%) than GM-CSF (2.1%; 95% CI, 0% to 4.5%]; odds ratio, 8.9; P < .001). Overall response rate was also higher in the T-VEC arm (26.4%; 95% CI, 21.4% to 31.5% v 5.7%; 95% CI, 1.9% to 9.5%). Median OS was 23.3 months (95% CI, 19.5 to 29.6 months) with T-VEC and 18.9 months (95% CI, 16.0 to 23.7 months) with GM-CSF (hazard ratio, 0.79; 95% CI, 0.62 to 1.00; P = .051). T-VEC efficacy was most pronounced in patients with stage IIIB, IIIC, or IVM1a disease and in patients with treatment-naive disease. The most common adverse events (AEs) with T-VEC were fatigue, chills, and pyrexia. The only grade 3 or 4 AE occurring in ≥ 2% of T-VEC–treated patients was cellulitis (2.1%). No fatal treatment-related AEs occurred. Conclusion T-VEC is the first oncolytic immunotherapy to demonstrate therapeutic benefit against melanoma in a phase III clinical trial. T-VEC was well tolerated and resulted in a higher DRR (P < .001) and longer median OS (P = .051), particularly in untreated patients or those with stage IIIB, IIIC, or IVM1a disease. T-VEC represents a novel potential therapy for patients with metastatic melanoma.

7033 Background: Carboplatin/vinorelbine (CV) and carboplatin/gemcitabine (CG) are novel 2-drug combinations in the treatment of NSCLC. In a randomized national multicenter phase III study in stage IIIB and IV patients (pts), we compared these regimens with respect to efficacy, toxicity and quality of life (QoL). Methods: Chemonaive pts with histologically or cytologically proven NSCLC, stage IIIB or IV and ECOG performance status (PS) 0–2 were eligible. There was no upper age limit. Pts received vinorelbine 25 mg/m2 or gemcitabine 1000 mg/m2, both administered on day 1 and 8, in combination with carboplatin (Chatelut AUC 4) at day 1. Three courses were administered in 3-week cycles. QoL questionnaires were completed at baseline, before each cycle and then every 8 weeks up to one year. Primary endpoints were survival and QoL and secondary endpoints toxicity and time to progression (TTP). Stratification was done for age, stage and PS, and the planned sample size per arm was minimum 200. The analyses were performed on an intention-to-treat basis Results: From Oct 2003 through Dec 2004, 433 pts from 33 institutions were randomized to CV (n=218) or CG (n=215). Follow-up was minimum one year. There was no difference in overall survival between the two arms (p=0.89). Median survival was 7.3 vs. 6.5 months and 1-year survival 28% and 31% in the CV and CG arm respectively. TTP was significantly longer in the CG arm (p=0.006) with median TTP 4.2 vs. 3.9 months. There was significantly more grade 3–4 anemia and thrombocytopenia in the CG arm (p<0.001) and more grade 3–4 leucopenia in the CV arm (p= 0.001). More pts in the CG arm needed transfusions of blood (p=0.003) or platelets (p=0.001). There was no difference between the arms with respect to neutropenic infections (p=0.87). QoL data are still being analyzed and will be presented at ASCO. Conclusions: Overall survival was similar in the two treatment arms. In the CG arm, the median TTP was longer, but grade 3–4 toxicity requiring interventions, was more frequent when compared to the VC arm. No significant financial relationships to disclose.

17083 Background: Monochemotherapy with gemcitabine (GEM) or vinorelbine is considered the standard treatment in elderly or poor performance (PS) patients (pts) with advanced NSCLC. Many topics report a synergic enhancement of antitumor effect of GEM if associated to Vindesine (VDS). The aim of this study is to evaluate if GEM combined to VDS produces an advantage in terms of overall survival (OS) compared to GEM alone without enhancement of toxicity. Methods: Chemonaive pts with stage IIIB/IV NSCLC, aged ≥ 70 years with PS < 2 or aged < 70 years with PS > 2 were enrolled. Pts were randomized to receive either GEM 1200 mg/m2 day 1 and 8 every 21 days for three cycles (arm 1) or GEM 1000 mg/m2 and VDS 3 mg/m2 (max dose 5 mg) both drugs infused on day 1 and 8 every 21 days for three cycles (arm 2). Pts of both arms received other three cycles in case of responsive or stable disease. Overall survival (OS) was the primary end-point, secondary end-points were time-to-progression and toxicity. First interim analysis was planned at 120 pts enrolled. Results: From May 2002 to December 2005, 107 pts from 13 Italian institutions were enrolled. Their characteristics are: 24 stage IIIB and 83 stage IV, 79 pts with ≥ 70 years (ECOG PS 0–1) and 28 pts with < 70 years (ECOG PS > 2). In arm 1 there were enrolled 55 pts while 52 pts in arm 2: both arms were well balanced with pts characteristics. Conclusions: The enrollment of this phase III trial is ongoing: we are achieving first step for an interim analysis to assess if GEM associated to VDS produces an advantage in terms of OS compared to standard treatment as GEM in monochemotherapy without toxicity enhancement.

17134 Background: Chemotherapy prolongs survival of patients with advanced non-small cell lung cancer (NSCLC). Subanalysis of a phase III trial suggests better outcome of treatment with platinum and gemcytabine containing combinations in patients with adenocarcinoma. Also docetaxel is active in NSCLC. The aim of this phase II trial was to wvaluate the efficacy and tolerability of third generation doublet (GCB and DXL) in cheminaive patients with advanced adenocarcinoma of lung. Methods: Chemonaive patients with biopsy proven stage IIIB or IV adenocarcinoma of lung not suitable for curative radical treatment witk KPS 80–100 received 2 to 6 chemotherapy cycles (DXL 80 mg/m2 day 1 plus GCB 1000 mg/m2 day 1 and 8; every 21 days). Response rate and tolerability were the primary endpionts, while the overall survival and 1-year survival were secondary objectives. Results: Twenty eigth patients (15 women, 13 men) with median age 59,04 (range 40–74) were treated. Twenty three patients was analysed. Stage IV was found in 23 (95.8%) and stage IIIB in 1 (4.2%) patients. Partial response was achiwed in 9 (37,5%), stable disease in 12 (50%) and pregressive disease in 3 (12,5%) patients. Median time to progression was 8, 37 months (range: 1.5–14 months). Median overall survival was 12,87 months (range: 4–35 months). Eleven (11) patients received second-line therapy (6-RT, 11-CTH). All patients received 94 cycles of chemotherapy (range: 2, median 3,9). Total dose of docetaxel on each patients was fro 120 to 960 mg (median 556 mg). Total dose of gemcytabine on each patients was from 2100 mg to 21000 mg (median 10475 mg). Treatment toxicicy presents on the table . Conclusions: First line gemcytabine and docetaxel containing chemotherapy is effective palliative treatment for patients with advanced AC of the lung. Toxicity was within acceptable limits.

Unresectable Stage

TPS8604 Background: T-VEC (formerly OncoVEXGM-CSF) is an oncolytic HSV1 that selectively replicates in tumors. The proposed MOA includes lytic destruction of injected tumors and induction of a systemic anti-tumor immune response enhanced by local GM-CSF expression. Intratumoral T-VEC tx in a 50-patient (pt) ph II study in advanced melanoma (Stage IIIc-IVM1c) was well tolerated and achieved a high rate and duration of response, including 20% CR (Senzer et al., JCO 2009; 27: 5763-71). As immune effects may be delayed, progressive disease (PD) often occurred before response. Based on the ph II data, a randomized ph III trial of T-VEC in unresectable melanoma (the OPTiM study; clinical trials registry NCT00769704) was designed taking into account the response patterns seen with T-VEC and other immunotherapeutic agents. T-VEC is the first "armed" oncolytic agent to enter pivotal testing worldwide. Methods: OPTiM compares the efficacy and safety of intratumoral T-VEC to sc GM-CSF in 430 pts with treated or untreated unresectable Stage IIIb-IVM1c melanoma stratified by typical prognostic factors. Pts are randomized 2:1 to T-VEC (priming dose of up to 4 x 106 pfu intratumorally then 3 wks later by up to 4 x 108 pfu Q2W) or GM-CSF 125 µg/m2 qd sc x 14 days every 28 days. Key eligibility criteria are ≥ 18 yrs old, ECOG 0-1, and at least 1 injectable cutaneous, sc, or nodal tumor. The primary endpoint is durable response rate (DRR: CR or PR continuously maintained for ≥ 6 mo initiating within 12 mo of starting tx; secondary endpoints include OS. Responses are subject to independent review. Pts are treated until wk 24, even with PD. Thereafter pts are treated until clinically significant PD, CR, or for 1 yr. The study has 90% power to show a 10% difference in DRR with 2-sided Fisher Exact Test (α = 5%). Enrollment closed in July 2011 with 439 pts randomized in the US, UK, S Africa, and Canada. Interim analysis in Dec 2010 on 75 pts on study > 9 mo concluded that the study should continue. Results are expected during 2012. Conclusions: T-VEC provides a novel potential tx for melanoma. This pivotal ph III study is expected to report during 2012.
