P1.01-34 - Docetaxel Plus Ramucirumab with Prophylactic PEG-G-CSF Support for Chemo-NaïVe Elderly NSCLC Patients: A Phase II Study (WJOG9416L) (ID 12400)
16:45 - 18:00 | Author(s): Kazumi Nishino
- Abstract
Background
Docetaxel monotherapy is the standard of care for chemo-naïve Japanese elderly patients with advanced non-small cell lung cancer (NSCLC), according to our results of phase III trial comparing docetaxel and vinorelbine monotherapies (WJTOG9904). In a pivotal phase III study (REVEL), docetaxel plus ramucirumab demonstrated superior response rate (RR) and progression-free survival (PFS) over docetaxel monotherapy in second-line setting for advanced NSCLC. These differences in RR and PFS were translated into overall survival (OS) benefit. This evidence prompted us to investigate docetaxel plus ramucirumab for chemo-naïve elderly patients. However, in a similarly designed Japanese randomized phase II trial (JVCG trial), febrile neutropenia (FN) was observed in 34.2% of docetaxel plus ramucirumab arm. This high incidence of FN is a clinical concern when using docetaxel plus ramucirumab for elderly patients. The ASCO practice guideline recommends primary prophylactic granulocyte-colony stimulating factor (G-CSF) when the risk of FN is 20% or higher. PEGylated-G-CSF (pegfilgrastim) administered once a cycle demonstrated reduction of FN incidence in many types of cancers. Based on the above background, we considered that primary prophylactic PEG-G-CSF would be beneficial for elderly NSCLC patients who received docetaxel plus ramucirumab.

This is a prospective multicenter, single-arm, phase II study conducted by West Japan Oncology Group (WJOG). Main inclusion criteria includes: chemo-naïve; aged ≥75; histologically or cytologically confirmed NSCLC; ECOG PS 0/1; adequate organ functions; with measurable disease; without contraindication of ramucirumab; written informed consent; and estimated life expectancy of at least 3 months. Intravenous docetaxel (60 mg/m2, day 1) plus ramucirumab (10 mg/kg, day 1) with subcutaneous PEG-G-CSF (3.6 mg, day 2) every 3 weeks is administered until progression. Continuous docetaxel or ramucirumab monotherapy is permitted when intolerable toxicities occur but clinical benefit is obtained by each drug. The primary endpoint is objective response rate (ORR). Secondary endpoints are PFS, OS, disease control rate, and safety. We assumed that the threshold and expected ORR were 20% and 35%, respectively. Based on this, the number of patients was calculated to be 59 to provide a power of 80% with probability of one-sided type I error being 0.05. Taking ineligible patients into account, the sample size was set at 65. When the study results are promising, we plan to conduct a phase III trial to compare docetaxel plus ramucirumab with PEG-G-CSF support vs. docetaxel monotherapy for chemo-naïve elderly NSCLC patients. Clinical trial information: UMIN000030598.

P1.14-03 - Phase II Trial of Amrubicin and Cisplatin Chemotherapy for Invasive Thymoma: WJOG5509L (ID 11706)
16:45 - 18:00 | Author(s): Kazumi Nishino
- Abstract
Background
Background: Platinum and anthracycline combination chemotherapy has been considered as the standard treatment for invasive thymoma for a long time. The clinical activity of amrubicin (AMR)—an anthracycline agent—has been previously reported in the treatment of small cell lung cancer (SCLC). The aim of this study was to evaluate the efficacy and safety of the combination of AMR and cisplatin (CDDP) in patients with advanced or recurrent invasive thymoma.

Methods: Patients were eligible for inclusion in the study if they met the following criteria: were chemo-naive; not amenable to curative surgery or radiotherapy; and presented with histologically confirmed invasive thymoma in each site. The patients received AMR (35 mg/m2, on days 1–3) and CDDP (60 mg/m2, on day 1) every 3 weeks, for up to 4 cycles. The primary endpoint was the objective response rate (ORR) assessed by an independent review, and the secondary endpoints were overall survival (OS) and toxicity profile of the patients. Based on the SWOG 2-stage design, the planned sample size of 40 patients was determined to reject the ORR of 60% under the expectation of 80% with a power of 0.85 and a type I error of 0.05. This trial is registered with the UMIN Clinical Trials Registry, number UMIN000003933.

Results: From August 2010 to November 2014, a total of 26 patients were enrolled at 14 institutions in Japan. During the planned interim analysis in April 2014, the ORR of the 20 patients who had been enrolled so far, was assessed via independent review and found to be 55.6% (11/20), resulting in the early termination of this study because of its futility. In the final assessment, the ORR was 54.2% (95% confidence interval, 32.8–74.4) and the disease control rate was 95.8%. The OS did not reach the median value. The major grade 3 or 4 toxicities noted were neutropenia (96.2%), anemia (26.9%), anorexia (11.5%) and febrile neutropenia (26.9%), albeit these were transient and manageable. There was one treatment-related death.

Conclusions: The combination of AMR with CDDP had minimal activity on invasive thymoma. Thus, we do not recommend further study of this regimen.
