A Pilot Study (SWOG S0429) of Weekly Cetuximab and Chest Radiotherapy for Poor-Risk Stage III Non-Small Cell Lung Cancer

PURPOSE: Stage III non-small cell lung cancer (NSCLC) patients with poor performance status (PS) or co-morbidities are often not candidates for standard chemoradiotherapy (chemoRT) due to poor tolerance to treatments. A pilot study for poor-risk stage III NSCLC patients was conducted combining cetuximab, a chimeric monoclonal antibody targeting epidermal growth factor receptor (EGFR), with chest radiation (RT). METHODS: Stage III NSCLC patients with Zubrod PS 2, or Zubrod PS 0-1 with poor pulmonary function and co-morbidities prohibiting chemoRT were eligible. A loading dose of cetuximab (400 mg/m(2)) was delivered week 1, followed by weekly cetuximab (250 mg/m(2))/RT to 64.8 Gy in 1.8 Gy daily fractions, and maintenance weekly cetuximab (250 mg/m(2)) for 2 years or until disease progression. H-score for EGFR protein expression was conducted in available tumors. RESULTS: Twenty-four patients were enrolled. Twenty-two were assessed for outcome and toxicity. Median survival was 14 months and median progression-free survival was 8 months. The response rate was 47% and disease control rate was 74%. Toxicity assessment revealed 22.7% overall \u3e /=Grade 3 non-hematologic toxicities. Grade 3 esophagitis was observed in one patient (5%). The skin reactions were mostly Grade 1 or 2 except two of 22 (9%) had Grade 3 acne and one of 22 (5%) had Grade 3 radiation skin burn. Grade 3-4 hypomagnesemia was seen in four (18%) patients. One patient (5%) had elevated cardiac troponin and pulmonary emboli. H-score did not reveal prognostic significance. An initially planned second cohort of the study did not commence due to slow accrual, which would have added weekly docetaxel to cetuximab/RT after completion of the first cohort of patients. CONCLUSION: Concurrent weekly cetuximab/chest RT followed by maintenance cetuximab for poor-risk stage III NSCLC was well tolerated. Further studies with larger sample sizes will be useful to establish the optimal therapeutic ratio of this regimen

Toxicity Profile and Pharmacokinetic Study of A Phase I Low-Dose Schedule–Dependent Radiosensitizing Paclitaxel Chemoradiation Regimen for Inoperable Non–Small-Cell Lung Cancer

We report the toxicity profile and pharmacokinetic data of a schedule-dependent chemoradiation regimen using pulsed low-dose paclitaxel for radiosensitization in a phase I study for inoperable non-small cell lung cancer (NSCLC)

Preclinical and Pilot Clinical Studies of Docetaxel Chemoradiation for Stage III Non–Small-Cell Lung Cancer

Local and distant failure rates remain high despite aggressive chemoradiation (CRT) treatment for stage III non-small cell lung cancer (NSCLC). We conducted preclinical studies of docetaxel cytotoxic and radiosensitizing effects on lung cancer cell lines and designed a pilot study to target distant micrometastasis upfront with one-cycle induction chemotherapy, followed by low-dose radiosensitizing docetaxel CRT

Phase 1/2 Dose Escalating Study of Twice-Monthly Pemetrexed and Gemcitabine in Patients with Advanced Cancer and Non-small Cell Lung Cancer

IntroductionPemetrexed is synergistic with gemcitabine in preclinical models of non-small cell lung cancer (NSCLC). The optimal dose and utility of gemcitabine and pemetrexed was evaluated in a dose-escalating study.MethodsThe phase 1 study included patients with advanced tumors, whereas the phase 2 study included patients with locally advanced or metastatic NSCLC. Gemcitabine was infused over 30 minutes, followed by pemetrexed administered over 10 minutes on day 1 of a 14-day cycle. Treatment continued for 12 cycles or until disease progression. All patients received folic acid, Vitamin B12, and steroid prophylaxis.ResultsMaximum tolerated dose was gemcitabine 1500 mg/m2, followed by pemetrexed 500 mg/m2. Fifty-three patients (29 male, 24 female) were enrolled in the phase 2 study. Response rate was 20.8% (95% CI: 0.108–0.341), and the clinical benefit rate (CR + PR + SD) was 64.2%. Median time to disease progression was 4.6 months (95% CI: 2.79–6.18), median survival was 10.1 month (95% CI: 5.95–14.09, censorship = 20.75%), and 1-year survival was 41.0%. Common grade 3 or 4 adverse events (% of patients) were neutropenia (28.3%), fatigue (22.6%), and febrile neutropenia (9.4%).ConclusionsTwice-monthly gemcitabine and pemetrexed was well tolerated, with overall survival and clinical benefit indicating disease activity in NSCLC patients

A Pilot Trial of Cisplatin/Etoposide/Radiotherapy Followed by Consolidation Docetaxel and the Combination of Bevacizumab (NSC-704865) in Patients With Inoperable Locally Advanced Stage III Non-Small-Cell Lung Cancer: SWOG S0533

BACKGROUND: The aim of this trial was to determine feasibility of incorporating bevacizumab (B) into concurrent chemoradiotherapy (CRT) for locally advanced non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS: Patients with unresectable stage III NSCLC, performance status of 0 to 1, and adequate organ function were accrued in 2 strata, low- and high-risk (squamous histology, hemoptysis, tumor with cavitation and/or adjacent to a major vessel). Cohort 1 patients received cisplatin 50 mg/m(2) days (d) 1 and 8, etoposide 50 mg/m(2) (d 1-5) for 2 cycles concurrent with radiotherapy (64.8 Gy) followed by docetaxel (D) 75 mg/m(2) and B 15 mg/kg for 3 cycles. If safety was established, then accrual would continue to cohort 2 (B, d 15, 36, 57) and then subsequently to cohort 3 (B, d 1, 22, 43). RESULTS: Twenty-nine patients (17 low- and 12 high-risk) registered to cohort 1. Twenty-six patients (including 4 squamous, 1 adenosquamous) were assessable. Twenty-five completed CRT. Grade 3/4 toxicities during CRT included acceptable rates of hematologic toxicity, esophagitis, and pneumonitis. Of 21 assessable for safety with D/B consolidation, major adverse events were pneumonitis (2 Grade 3) and 2 episodes of fatal hemoptysis in the high-risk group, resulting in closure of this stratum. The low-risk stratum subsequently closed because of slow accrual. Median overall survival was 46 months for low-risk and 17 months for high-risk strata. CONCLUSION: Bevacizumab was not safely integrated into CRT for stage III NSCLC in patients considered at high risk for hemoptysis. In lower risk patients, data are insufficient to determine safety or efficacy
