3075 Background: L-BLP25 is an innovative cancer vaccine that incorporates a synthetic MUC1 lipopeptide in a liposomal delivery system. L-BLP25 is expected to elicit an immune response to cancer cells that express MUC1. Previous clinical studies have demonstrated that L-BLP25 has the potential to extend survival of pts with stage IIIB locoregional NSCLC (Butts C et al., JCO 2005; 23:6674–6681). The present ph I-II study was designed to assess the safety of the current formulation of L-BLP25 using a monophosphoryl lipid A in pts with unresectable stage IIIA and stage IIIB NSCLC. Methods: Pts with stable disease or an objective response to upfront radical therapy with chemoradiation for unresectable stage III NSCLC, plus ECOG 0–1 were eligible. All pts were vaccinated according to a previously described schedule (1). Maintenance immunizations were administered every 6-wks until disease progression. Primary and secondary endpoints were safety and survival respectively. Results: Twenty-two pts were recruited at 7 sites in Canada. 16 pts were evaluated for this interim safety analysis (8 stage IIIA, 8 stage IIIB, median age; 57, ECOG 0 56%, concurrent chemotherapy; 93.8%). Thirteen pts had a partial response and 3 had stable disease following chemoradiation. Thirteen pts experienced an adverse event (AE) during the first 4 vaccinations of which 7 pts had a L-BLP25 related adverse event. Grade 1/2 AEs related to L-BLP25 ≥10% included fatigue, dyspnea, insomnia, anorexia, headache, diarrhea, paresthesia, abdominal pain, influenza-like illness, urinary tract infection and peripheral neuropathy. No pts discontinued L-BLP25 due to an AE and no grade 3/4 AEs related to L-BLP25 were reported. Six pts (37.5%) had an injection site reaction. As of September 2006, 10 pts were still on study treatment. Conclusions: This formulation of L-BLP25 was well tolerated and the side effect profile was similar to that seen in previous studies (1). A controlled global multi-center phase III trial is underway to further evaluate L-BLP25 in this patient population. No significant financial relationships to disclose.

7527 Background: Æ-941 is a shark cartilage extract with antiangiogenic properties. We conducted a placebo-controlled trial testing Æ-941, with IC and CRT, in unresectable stage III NSCLC. Methods: Eligibility criteria included performance status (PS) < 2, weight loss < 10%. Subjects received one of two treatment regimens depending on site of enrollment: carboplatin (C) (AUC 6) and paclitaxel (P) (200 mg/m2) × 2 cycles followed by CRT (60 Gy/30 fractions) with weekly C (AUC 2) and P (45 mg/m2) × 6 doses or cisplatin (CDDP) (75 mg/m2, d1) and vinorelbine (V) (30 mg/m2, d1 and 8) × 2 cycles followed by CRT (60 Gy/30 fractions) with CDDP (75 mg/m2, day 1) and V (15 mg/m2, d1 and 8) × 2 cycles. Subjects were randomized to receive Æ-941 (Arm A) or placebo (Arm B), 120 mL orally twice daily, at the start of IC and continuing after CRT as maintenance therapy. Randomization was stratified for stage, gender, and type of chemotherapy. The primary endpoint was overall survival (OS), with a planned sample size of 756 subjects providing 80% power to detect a 25% difference in OS, assuming a control arm median survival time (MST) of 13 months, type I error 0.05. Results: Between 6/00 and 2/06, 384 subjects were enrolled onto the trial and randomized. In 2/06 the trial was closed to new patient entry due to insufficient accrual. This final analysis is based on 379 randomized and eligible subjects (188 arm A, 191 arm B). Subject characteristics: 60% male, median age 63 years (range 37–84), 56% stage IIIB, 58% C-based chemotherapy, median follow-up 3.7 years. There was no significant difference in OS between arms A and B, with MSTs of 14.4 (95% CI 12.6–17.9) and 15.6 (95% CI 13.8–18.1) months, respectively (log-rank p=0.73). OS by pre-specified stratification factors: stage IIIB vs IIIA (MST 13.9 vs. 17.4 months, p=0.25), C vs. CDDP chemotherapy (MST 14.4 vs. 16.7 months, p=0.13), and male vs. female (MST 15.7 vs. 15.1 months, p=0.74). The study drug was well tolerated. Fewer subjects in arm A experienced grade 3 or higher adverse events (66% vs. 77%, p=0.018). Conclusions: The addition of Æ−941 to IC and CRT does not improve OS in patients with unresectable stage III NSCLC. No significant financial relationships to disclose.

e18503 Background: Concurrent chemoradiation is standard of care for most patients with unresectable stage III A/B NSCLC but no standard chemotherapy regimen/schedule has been established. We conducted an experience to evaluate the efficacy and toxicity of a combination consisting of weekly docetaxel/cisplatin and radiotherapy in patients with unresectable stage III A/B NSCLC. Methods: Unresectable stage III A/B NSCLC pts with a good performance status (ECOG PS 0–1) were eligible. Patients with stage IIIB were chemonaive, while patients with stage IIIA were inoperable after a first line platinum-based chemotherapy. Treatment consisted of docetaxel 25 mg/m2 IV infusion followed by cisplatin 25 mg/m2 IV infusion was administered weekly during concurrent thoracic radiotherapy. Concurrent 3D-conformal RT thoracic radiation consisted of 45 Gy (1.8 Gy fractions 5 days/wk for first five weeks. Results: From 2006/01 to 2008/04, 16 pts were enrolled and all were evaluable for toxicity and response. Pt. characteristics: median age- 68 years (54–77), 80% males. Nine pts had stage IIIA (56%) and 7 patients had stage IIIB (44%).Histology subtypes included epidermoid (25%) and adenocarcinoma (75%). Radiologic response was seen in 11 patients (68%). Four patients had a stable disease (25%). Disease progression has occurred in 1 pt. Six patients undergone surgery after chemo-radiotherapy (37%). Four patients (25%) underwent a radical resection without residual mediastinal malignant disease. Toxicity was mild. Conclusions: Weekly docetaxel/cisplatin with concurrent 3D-conformal RT thoracic radiation plus is a well-tolerated out-patient regimen. and is feasible by multi-physicians collaboration group.

TPS8572 Background: In China, the standard of care for patients with unresectable Stage III NSCLC is platinum-based doublet chemotherapy given concurrently or sequentially with radiotherapy. However, the median progression-free survival (PFS) of those patients is poor (approximately 8-10 months) and 5-year overall survival (OS) rate is only 15%. Recently, treatment with durvalumab resulted in significantly longer PFS and OS than placebo for patients with locally advanced/unresectable NSCLC whose disease did not progress after definitive concurrent chemoradiotherapy (cCRT) in PACIFC trial. CS1001 is the first full-length, fully human programmed death ligand-1 (PD-L1) targeted immunoglobin G4 (IgG4, s228p) monoclonal antibody (mAb) developed by the OMT transgenic rat platform. The Phase Ia/Ib study (GEMSTONE-101, NCT03312842) demonstrated that CS1001 was well tolerated and had promising anti-tumor activities across a range of tumors including NSCLC. GEMSTONE-301 is a randomized, double-blind, Phase III study to compare the efficacy and safety of CS1001 versus placebo as consolidation therapy in Stage III unresectable NSCLC patients. This is the first Phase III trial on an anti-PD-(L)1 mAb initiated in China for this indication. Methods: In this trial, eligible patients with locally advanced/unresectable (Stage III) NSCLC who have not progressed after prior concurrent/sequential CRT are 2:1 randomized to receive CS1001 1200 mg, every 3 weeks or placebo, every 3 weeks. Stratification factors for randomization include ECOG status (0 versus 1), chemoradiotherapy (concurrent versus sequential) and total radiotherapy dose ( < 60 Gy versus ≥ 60 Gy). Study treatment will be given for up to 24 months or until disease progression, intolerable toxicity, consent withdrawal, or discontinuation for other reason. Tumor assessments will be performed every 9 weeks in the first year and every 12 weeks thereafter by RECIST v1.1. AEs will be monitored throughout the study and graded according to NCI-CTCAE v4.03. Primary endpoint is PFS evaluated by investigators according to RECIST v1.1. Secondary endpoints are PFS evaluated by Blinded Independent Center Review (BICR), objective response rate, OS, time to death/distant metastasis (TTDM), safety and pharmacokinetics (PK) profile. Enrollment is ongoing across sites in China and will continue until 402 patients are randomized. Clinical trial information: NCT03728556.

8531 Background: Concurrent chemoradiotherapy is the standard treatment for patients(pts) with unresectable stage IIIA/IIIB NSCLC. In EGFR mutant pts, tyrosine kinase inhibitor(TKI) exhibits clinical benefits over chemotherapy regimens in terms of efficacy and safety as well as specific enhancement of radiation effects. This multicenter, randomized, open-label, phase II trial aimed to compare the erlotinib and etoposide/cisplatin with concurrent radiotherapy (RT) in pts with EGFR-mutant. Methods: Histopathology/cytology confirmed stage IIIA/B unresectable NSCLC pts (age 18-75) with ECOG PS 0-1 and EGFR exon 19 or 21 mutation were included and randomized (1:1) into two arms: erlotinib (E) and etoposide/cisplatin (EP). E arm was treated with oral erlotinib (150mg/day for 2 years or till either disease progression or intolerable toxicities) and RT (200cGy/day, 5 days/week for 6 weeks from first day erlotinib). EP arm was treated with sequential etoposide (50 mg/m2 IV days 1-5, 29-33) and cisplatin (50mg/m2IV day 1,8, 29,36) and RT (from first day drug). Primary endpoint is progress free survival (PFS). Secondary endpoints are objective response rate(ORR), local control rate(LCR), overall survival(OS), quality of life(QoL) and safety. Results: 252 pts were screened, and 41 were enrolled into E(n=20) and EP(n=21) arms. Characteristics of age, sex, histologic type, N2, EGFR 19 and 21 mutation were well balanced in each arm. Comparing with EP, median PFS of E arm was significantly improved (27.86 vs 6.41 months; HR 0.053, 95% CI: 0.006-0.463; P<0.001). ORR and DCR were 60.0% vs. 38.1%( P=0.217), and 65% vs. 47.6%( P=0.350), respectively. Two arms had same incidence of adverse effects (CTCAE Grade≥1, 86.7%[13/15]), and most common sAE(Grade≥3) was rash (20%, 3/15) and hematological toxicity(26.7%, 4/15), respectively. Conclusions: In unresectable stage III EGFR mutant NSCLC pts, concurrent erlotinib/RT provides a statistically significant PFS improvement with well tolerability. These results warrant a phase III study to confirm. (RECEL, NCT01714908). Clinical trial information: NCT01714908.

BackgroundPrevious findings from the MASTERKEY-265 phase 1b study showed that the combination of T-VEC and pembrolizumab was well tolerated and produced a high complete response (CR) rate of 43% in patients with advanced melanoma.1 The 3-year progression-free survival (PFS) and overall survival (OS) rates at that time were 53.6% and 71%, respectively. Here, we report the results of the long-term follow-up efficacy analyses.MethodsThe MASTERKEY-265 phase 1b trial (NCT02263508) was an open-label, single-arm study that enrolled patients who had unresectable, stage IIIB-IVM1c melanoma with injectable, measurable lesions and no prior systemic treatment. T-VEC was administered intralesionally at the approved dosing starting day 1 of week 1. Pembrolizumab (200 mg) was administered intravenously Q2W beginning on day 1 of week 6. The maximum treatment period was 2 years. The primary endpoint was dose-limiting toxicities; key secondary endpoints included objective response rate and PFS per modified irRC, OS, and safety.ResultsAs of the data cutoff (Mar 2, 2020), all 21 patients enrolled were off treatment; 6 died and 15 are in long-term follow-up. The median follow-up time was 58.6 months (range: 1.4–61.6). The CR rate remained 43% (9/21 patients). Twelve of the 13 responders (92.3%) are still in response, including all 9 patients with a CR. Median duration of response was not reached (range: 2.8+–54.3+ months). Median PFS and OS were not reached at the data cutoff. KM estimates of 4-year PFS and OS rates were 55.9% and 71.4%, respectively, which have held stable since the 3-year analysis. Patients who achieved a CR or partial response had better OS (p=0.0056) compared to those who did not respond. Median OS for non-responders was 24.4 months and was not reached for responders. No additional safety signals were detected.ConclusionsAt almost 5 years of follow-up, median PFS and OS were not reached for patients treated with the combination of T-VEC and pembrolizumab in this phase 1b study of unresectable metastatic melanoma. 92% of responders remained in response with improved OS observed in responders compared with non-responders. The corresponding randomized phase 3 trial has completed enrollment and is currently ongoing.Trial RegistrationNCT02263508Ethics ApprovalThe study was approved by the Ethics Board of each institution involved in this study and can be produced upon request.ReferenceLong G, Dummer R, Andtbacka R, et al.

8511 Background: In the placebo-controlled Phase III PACIFIC trial of patients with unresectable Stage III NSCLC whose disease had not progressed after platinum-based concurrent chemoradiotherapy (cCRT), durvalumab improved overall survival (OS) (stratified hazard ratio [HR] 0.68; 95% confidence interval [CI] 0.53–0.87; p=0.0025; data cutoff [DCO] Mar 22, 2018) and progression-free survival (PFS) (stratified HR 0.52, 95% CI 0.42–0.65; p<0.0001; DCO Feb 13, 2017) based on the DCOs used for the primary analyses, and the degree of benefit remained consistent in subsequent updates. Durvalumab was associated with a manageable safety profile, and did not detrimentally affect patient-reported outcomes, compared with placebo. These findings established consolidation durvalumab after CRT (the ‘PACIFIC regimen’) as the standard of care in this setting. We report updated, exploratory analyses of OS and PFS, assessed approximately 5 years after the last patient was randomized. Methods: Patients with WHO PS 0/1 (and any tumor PD-L1 status) whose disease did not progress after cCRT (≥2 overlapping cycles) were randomized (2:1) 1–42 days following cCRT (total prescription radiotherapy dose typically 60–66 Gy in 30–33 fractions) to receive 12 months’ durvalumab (10 mg/kg IV every 2 weeks) or placebo, stratified by age (<65 vs ≥65 years), sex, and smoking history (current/former smoker vs never smoked). The primary endpoints were OS and PFS (blinded independent central review; RECIST v1.1) in the intent-to-treat (ITT) population. HRs and 95% CIs were estimated using stratified log-rank tests in the ITT population. Medians and OS/PFS rates at 60 months were estimated with the Kaplan–Meier method. Results: Overall, 709/713 randomized patients received treatment in either the durvalumab (n/N=473/476) or placebo (n/N=236/237) arms. The last patient had completed study treatment in May 2017. As of Jan 11, 2021 (median follow-up duration of 34.2 months in all patients; range, 0.2–74.7 months), updated OS (stratified HR 0.72, 95% CI 0.59–0.89; median 47.5 vs 29.1 months) and PFS (stratified HR 0.55, 95% CI 0.45–0.68; median 16.9 vs 5.6 months) remained consistent with the results from the primary analyses. The 60-month OS rates were 42.9% and 33.4% with durvalumab and placebo, respectively, and 60-month PFS rates were 33.1% and 19.0%, respectively. Updated treatment effect estimates for patient subgroups will be presented. Conclusions: These updated survival analyses, based on 5-year data from PACIFIC, demonstrate robust and sustained OS plus durable PFS benefit with the PACIFIC regimen. An estimated 42.9% of patients randomized to durvalumab remain alive at 5 years and approximately a third remain both alive and free of disease progression. Clinical trial information: NCT02125461.

TPS8585 Background: Non-small cell lung cancer (NSCLC) is the most common cause of cancer death worldwide highlighting the importance of improving current therapeutic options. In particular, elderly and frail patients are not only underrepresented in clinical trials, but also frequently do not receive standard treatment regimens due to comorbidities. For example, patients with unresectable stage III NSCLC who are unfit for chemotherapy (CHT) do not benefit from the recent seminal therapy algorithm change for this disease, i.e. consolidation therapy with the immune checkpoint inhibitor (ICI) durvalumab after combined radiochemotherapy (RChT). Instead, these patients are treated with radiotherapy only, raising the serious concern of undertreatment. This issue is addressed by the TRADE-hypo clinical trial that investigates a novel therapy option for NSCLC stage III patients not capable of receiving CHT. To this end, thoracic radiotherapy (TRT) is administered together with durvalumab, employing the synergism created by the combination of restoring anti-tumor immune response by the ICI with the induction of immunogenicity by irradiation. The latter effect has been suggested to be further boosted by hypofractionated radiotherapy, which could also be more practicable for the patient. Taken these considerations into account, the TRADE-hypo trial addresses safety and efficacy of durvalumab therapy combined with either conventional or hypofractionated TRT. Methods: The TRADE-hypo trial is a prospective, randomized, open-label, multicentric phase II trial. Eligible patients are diagnosed with unresectable stage III NSCLC and not capable of receiving sequential RChT due to high vulnerability as reflected by a poor performance status (ECOG 2 or ECOG1 and CCI≥ 1) and/or high age (≥ 70)]. Two treatment groups are evaluated: Both receive durvalumab (1,5000 mg, Q4W) for up to 12 months. In the CON-group this is combined with conventionally fractionated TRT (30 x 2 Gy), while in the HYPO-group patients are treated with hypofractionated TRT (20 x 2.75 Gy). In the HYPO-arm, a safety stop-and-go lead-in phase precedes full enrollment. Here, patients are closely monitored with regard to toxicity (i.e., pneumonitis grade ≥ 3 within 8 weeks after TRT) in small cohorts of 6. The primary objective of the trial is safety and tolerability. As a primary efficacy endpoint, the objective response rate after 3 months will be evaluated. Further endpoints are additional parameters of safety and efficacy, as well as the comprehensive collection of biomaterials to be analyzed regarding treatment-induced changes and potential novel biomarkers. As of February 10, 2021, 9 patients of planned 88 patients have been enrolled in the TRADE-hypo trial. Clinical trial information: NCT04351256.
