MINI37.06 - Randomized Phase II Trial of CODE or Amrubicin Plus Cisplatin Chemotherapy after Chemoradiotherapy for Limited-Disease Small Cell Lung Cancer (ID 1033)
19:00 - 19:05 | Author(s): N. Nogami
- Abstract
- Presentation
Background:
Four cycles of etoposide plus cisplatin (EP) concurrently with accelerated hyperfractionation thoracic radiotherapy (AHTRT) is the standard treatment for limited-disease small cell lung cancer (LD-SCLC). The objectives of this study were to evaluate efficacy and toxicities of CODE or amrubicin plus cisplatin (AP) chemotherapy following one cycle of EP and AHTRT in patients with LD-SCLC, and to select the promising arm for subsequent phase III trials.
Methods:
Eligibility criteria included patients with previously untreated LD-SCLC with measurable lesion, ECOG PS of 0-1, and 20-70 years of age. Eligible patients received one cycle of EP (etoposide 100 mg/m[2] on days 1-3 and cisplatin 80mg/m[2] on day 1) plus AHTRT (45Gy/ 30 fractions in 3 weeks). Patients who achieved CR, PR or SD were secondarily registered and randomized to receive either 3 cycles of CODE (cisplatin 25 mg/m[2] on days 1 and 8, doxorubicin 40 mg/m[2] on day 1, etoposide 80 mg/m[2] on days 1-3, and vincristine 1 mg/m[2] on 8 every 2 weeks) or 3 cycles of AP (amrubicin 40 mg/m[2] on days 1-3 and cisplatin 60 mg/m[2] on day 1 every 3 weeks). G-CSF was administered on the days when chemotherapy was not administered in CODE, or on day 5 to the day when a neutrophil count exceeded 5,000/µL in AP. Patients with CR after CODE or AP received prophylactic cranial irradiation. The primary endpoint was the one-year progression-free survival (PFS) after the second registration. Tumor responses were assessed with RECIST version 1.1 by the central review committee. A better regimen for phase III trial is determined with a randomized phase II selection design. The sample size was 72 randomized patients to detect >= 10% difference in one-year PFS with a probability of 80%.
Results:
From May 2011 to Jan 2014, 85 patients from 28 institutions were registered. After the induction EP plus AHTRT, 75 patients were randomized to CODE (n=39) or AP (n=36). Patient demographics were well balanced between the arms. One patient did not receive CODE and 34 (89%) of the 38 patients received 3 cycles of CODE, whereas 33 (92%) of the 36 patients received 3 cycles of AP. Grade 4 neutropenia, anemia and thrombocytopenia were observed in 47%, 21% and 16% of patients in CODE, and in 78%, 6% and 17% of patients in AP, respectively. Grade 3 non-hematological toxicities with the incidence of 5% or higher included febrile neutropenia (16%), hyponatremia (8%), hypokalemia (5%), fatigue (5%), and anorexia (5%) in CODE, and febrile neutropenia (42%), nausea (11%), anorexia (11%), fatigue (8%), esophagitis (6%) in AP. CR and PR were noted in 13 and 25 patients in CODE, and in 10 and 24 patients in AP, respectively. The median overall survival in the 74 patients was 42.8 months. The one-year PFS (95% CI) was 41.0 (25.7 - 55.8) % in CODE and 54.3 (36.6 - 69.0) % in AP.
Conclusion:
The one-year PFS seemed better in AP than in CODE. AP arm is considered to be the test regimen for the subsequent phase III trial.

ORAL17.03 - Biomarkers for Efficacy in JO25567 Study Evaluating Erlotinib plus Bevacizumab versus Erlotinib in Advanced NSCLC with EGFR Mutation (ID 306)
11:07 - 11:18 | Author(s): N. Nogami
- Abstract
- Presentation
Background:
Bevacizumab (B), an anti-vascular endothelial growth factor (VEGF) monoclonal antibody has been proven to provide additional efficacy benefit in combination with platinum-based chemotherapy for 1[st] line therapy of non-squamous non-small cell lung cancer (NSCLC). In JO25567 study, we observed that bevacizumab in combination with epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, erlotinib (E) also provided additional 6.3 months median progression free survival (PFS) in advanced EGFR mutation-positive non-squamous NSCLC. To try to understand this additional effect of bevacizumab, we investigated the predictive biomarkers related to angiogenesis comprehensively in JO25567 study. Clnical trials registry number: JapicCTI-111390
Methods:
We evaluated the biomarkers in blood and tissue samples. All samples were collected before E+B or E treatment in JO25567 study. Angiogenesis related ligands and soluble receptors in serum were analyzed by multiplex, bead-based suspension array. Single nucleotide polymorphisms (SNPs) or variable number of tandem repeats (VNTR) of angiogenesis related genes were analyzed by direct sequencing or electrophoresis after PCR for blood sample. VEGF-A concentration in plasma were analyzed by Immunological Multi-Parametric Chip Technique (IMPACT) assay. Messenger RNA of genes related to angiogenesis in tumor tissue were quantitated by multiplex TOF-mass spectrometry (MassARRAY). Immunohistochemistry of neuropilin and exploratory proteomics analysis were planned for surgically resected tumor tissues. PFS were used as an efficacy variable of prediction. Multivariate Fractional Polynomial (MFP) and Subpopulation Treatment Effect Pattern Plot (STEPP) were used for biomarker screening.
Results:
One hundred fifty-two patients were treated with E+B or E in JO25567 study. We analyzed 26 ligands or soluble receptors in 134 serum samples. Follistatin and leptin were identified as potential biomarkers by MFP. The interaction p-value with adjustment of covariates for biomarker and efficacy was 0.0168 for follistatin and 0.0049 for leptin. STEPP suggested that high follistatin related to limited bevacizumab efficacy and low leptin related to higher bevacizumab efficacy. SNPs could be analyzed in 135 blood samples. In 12 SNPs and 1 VNTR of 8 genes, no gene related to bevacizumab efficacy. Plasma samples were collected from 105 patients. Median VEGF-A concentration of E+B group and E group were 18.0 pg/mL and 18.8 pg/mL respectively and was one sixth or more lower than previously reported breast and gastric cancers. Hazard ratio of E+B comparing with E for was 0.23 (95% CI: 0.09-0.60) for low plasma VEGF and was 0.56 (95% CI: 0.26-1.25) for high plasma VEGF. This trend was not consistent with previously reported studies. We analyzed mRNA expression from 24 surgical resected tumors and no predictive value was observed. Because of limited number of surgically resected tumors obtained, we couldn’t proceed exploratory proteomics analysis nor evaluate predictive value of neuropilin expression.
Conclusion:
In this comprehensive predictive biomarker analysis, follistatin and leptin in blood were identified as potential biomarker candidates for E+B therapy.

P1.01-010 - Development of Skin Rash within the First Week Is a Potential Surrogate Marker of Effect in Afatinib for EGFR Mutant NSCLC (ID 1184)
09:30 - 09:30 | Author(s): N. Nogami
- Abstract
Background:
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are now key agents in EGFR-mutant non-small-cell lung cancer (NSCLC). In gefitinib or erlotinib monotherapy, its efficacy could be predicted by development of skin rash, however, it has not been fully evaluated if this is similarly the case with afatinib monotherapy.
Methods:
We retrospectively studied consecutive 49 patients with EGFR-mutant NSCLC who received afatinib therapy between 2009 and 2015. Relationship with several toxicities and tumor response was examined.
Results:
Figure 1Figure 2The Grade 2 or worse common adverse events (AEs) included skin rash in 17 patients (35%), diarrhea in 19 (39%) and mucositis in 15 (31%). Of these, number of patients who developed ≥ Grade 2 AEs within the first week was 5 (10%; skin rash), 12 (25%; diarrhea) and 4 (8%; mucositis). As for objective response, 21 (43%) of the 49 had partial response. In association with AEs and antitumor effect, those who had Grade 2 or worse skin rash within the first week tended to have better tumor response as compared with those who did not have (80% vs. 39%; p = 0.077).
Conclusion:
Our small study demonstrated that early development of skin rash might predict the response to afatinib monotherapy.

P2.03-013 - A Phase II Study of S-1 and Thoracic Irradiation for Elderly Pts with Locally Advanced Non-Small Cell Lung Cancer: Okayama Lung Cancer Study Group (ID 224)
09:30 - 09:30 | Author(s): N. Nogami
- Abstract
Background:
Although thoracic irradiation (TRT) is one of the standarad therapies in elderly pts with locally advanced non-small cell lung cancer (LA-NSCLC), its treatment outcome is still poor. We previously reported safety profiles of S-1, an oral fluoropyrimidine possesing a radio-sensitizing effect, and concurrent TRT in such population [Lung Cancer 2011]. Here, we investigated the efficacy and safety of S-1 with concurrent TRT for elderly pts with LA-NSCLC.
Methods:
Pts with stage III, aged >75 years and PS 0-1, and without any prior chemotherapy were eligible for this study. Pts were treated with S-1 (40 mg/m2/dose b.i.d on days 1-14 and 29-42) and TRT (60 Gy/30 fr over 6 weeks starting on day 1). Primary endpoint was response rate (RR), and required sample siza was 30 pts.
Results:
Between 2007 and 2012, 30 pts were enrolled (24 men; median age, 79 years; PS 1, 15; IIIa, 20; Sq, 12). Median Charlson score was 1 (range; 0-3). The proportion of actual dose schedule relative to the planned one of S-1 and TRT was 95 and 98%, respectively. Partial response was observed in 19 pts (63%; 95% confidence interval: 45-82%), which did not meet the endpoint. At the time of the analysis, 24 (80%) of the 30 had experienced recurrences; 13 (43%) were locoregional, 6(20%) distant, and 5 (17%) both locoregional and distant. At a median follow-up of 23.7 months, median progression-free survival and MST were 13.0 months and 27.9 months, respectively. Toxicities were generally mild, including G3/4 neutropenia (17%), G3 febrile neutropenia (7%) and G3 pneumonitis (10%). No toxic deaths occurred.
Conclusion:
This study did not meet the primary endpoint. However, concurrent S-1 and TRT yielded favorable survival data. Also, it was well-tolerated in elderly pts with LA-NSCLC

P3.01-085 - Randomized Phase II Study of Docetaxel plus Bevacizumab or Pemetrexed plus Bevacizumab for Elderly Non-Squamous NSCLC (TORG1323) (ID 1742)
09:30 - 09:30 | Author(s): N. Nogami
- Abstract
Background:
A randomized study comparing carboplatin plus weekly paclitaxel versus single-agent chemotherapy in elderly patients with non-small cell lung cancer (NSCLC) demonstrated a survival advantage for combination therapy, however, increased toxicity and treatment-related deaths were also observed. Thus, single agent approaches remain the standard of care and the improvement of treatment remains a challenge in elderly patients. The combination of bevacizumab and other platinum-based chemotherapies is the standard of care in non-elderly patients with non-squamous NSCLC. Additionally, a randomized phase II study suggested the improvement of efficacy for the combination of B plus single-agent pemetrexed or docetaxel compared with single-agent alone. Even in elderly patients, two prospective studies which we conducted demonstrated the feasibility of the combination of bevacizumab and single agent pemetrexed or docetaxel. Thus we plan this randomized phase II study (TORG1323) to select the optimal regimen for experimental arm of the future phase III study in elderly patients.
Methods:
TORG1323 is an open label multicenter randomized phase II study to compare docetaxel plus bevacizumab (DB) with pemetrexed plus bevacizumab (PB). The primary endpoint is progression free survival (PFS, assessed by independent review committee). The secondary endpoints are safety, PFS (assessed by investigators), objective response rate, overall survival, time to treatment failure and quality of life. Eligible patients are 75 years or older, have histologically or cytologically documented stage IIIb, IV or recurrent non-squamous NSCLC for which they had no received chemotherapy, ECOG performance status 0 or 1, and adequate organ function. Patients are randomly assigned to PB and DB arm (1:1). Bevacizumab is administered 15 mg/kg, pemetrexed is 500 mg/m[2] and docetaxel is 50 mg/m[2] every 3 weeks until disease progression or unacceptable toxicity. Selection design is adopted for this study. The planned sample size is 120 patients to yield 80 % power to select an optimal regimen correctly. Enrollment time is 2 years 8 months and follow-up time is 1 year. The first patient on this clinical trial was enrolled in April 2014. Further details can be found on UMIN Clinical Trials Registry (UMIN000012786). Figure 1

P3.07-005 - Maintenance Irinotecan Therapy in Extensive Disease Small Cell Lung Cancer: A Feasibility Study (ID 607)
09:30 - 09:30 | Author(s): N. Nogami
- Abstract
Background:
We performed a feasibility study of maintenance irinotecan therapy in patients with extensive disease small cell lung cancer (ED-SCLC) who responded to the induction irinotecan plus cisplatin (IP) therapy.
Methods:
The eligibility criteria included pts with ED-SCLC who responded to four cycles of induction IP therapy, ECOG performance status (PS) of 0 to 1, age of 20 to 70 years and adequate organ functions. Pts received irinotecan monotherapy at 60 mg/m2 on days 1, 8 and 15 of a 28-day cycles until disease progression. The primary endpoint was the proportion of treatment success (TS) at 6 months. Using a binomial design, a lower activity level (p0) of 0.25 and a target activity level (p1) of 0.50, the preplanned accrual of 28 patients was sufficient (alpha, 0.10 and power, 0.90).
Results:
Between August 2012 and August 2013, 22 pts were enrolled. However, accrual was discontinued because of the three grade 3 pneumonitis events (3 of 22 patients, 13.6%). Patient characteristics of the 22 eligible pts were as follows; the median age was 65 (54-70) years; 12 pts had a PS of 0, and 16 pts were male. The median number of cycles delivered was four (range, 1–31). Four of 22 (18.2%) patients achieved TS at 6 months. Median progression free survival and overall survival from the start of the maintenance irinotecan therapy were 3.2 months and 15.9 months, respectively. Grade ≥3 toxicities included neutropenia (4.5%), hyponatremia (4.5%), pneumonitis (13.6%) and cholangitis (4.5%). No treatment-related deaths occurred. Figure 1
Conclusion:
This trial was early terminated due to the unexpected toxicity, but maintenance irinotecan therapy was still active for a subset of ED-SCLC.
