A phase II study of induction chemotherapy followed by thoracic radiotherapy and erlotinib in poor-risk stage III non-small-cell lung cancer: results of CALGB 30605 (Alliance)/RTOG 0972 (NRG).

ABSTRACT: Patients with stage III non-small-cell lung cancer and poor performance status and/or weight loss do not seem to benefit from standard therapy. Based on the preclinical interaction between epidermal growth factor receptor inhibitors and radiation, we designed a trial of induction chemotherapy followed by thoracic radiotherapy and concurrent erlotinib.Patients with poor-risk unresectable stage III non-small-cell lung cancer received two cycles of carboplatin at an AUC of 5 and nab-paclitaxel at 100 mg/m on days 1 and 8 every 21 days, followed by erlotinib administered concurrently with thoracic radiotherapy. Maintenance was not permitted. Molecular analysis was performed in available specimens. Seventy-two eligible patients were required to test whether the 1-year survival rate was less than 50% or greater than or equal to 65% with approximately 90% power at a significance level of 0.10.From March 2008 to October 2011, 78 patients were enrolled, three of whom were ineligible. The median age was 68 (range, 39-88) and 32% were aged greater than or equal to 75 years. Patients were evenly distributed between stages IIIA and IIIB and the majority had performance status 2. The overall response rate was 67% and the disease control rate was 93%. Treatment was well tolerated. The median PFS and OS were 11 and 17 months, respectively. The overall 12-month OS was 57%, which narrowly missed the prespecified target for significance.Patients with poor-risk stage III non-small-cell lung cancer had better than expected outcomes with a regimen of induction carboplatin/nab-paclitaxel followed by thoracic radiotherapy and erlotinib. However, as per the statistical design, the 12-month OS was not sufficiently high to warrant further studies.

Project description:BackgroundNon-small cell lung cancer is the most common cause of cancer death worldwide, highlighting the need for novel therapeutic concepts. In particular, there is still a lack of treatment strategies for the group of elderly and frail patients, who are frequently not capable of receiving standard therapy regimens. Despite comprising the majority of lung cancer patients, this group is underrepresented in clinical trials. This applies also to elderly and frail patients suffering from unresectable stage III NSCLC, who are unfit for chemotherapy, and, therefore, cannot receive the standard therapy comprising of radiochemotherapy and the recently approved subsequent durvalumab consolidation therapy. These patients often receive radiotherapy only, which raises the concern of undertreatment. The TRADE-hypo trial aims at optimizing treatment of this patient group by combining radiotherapy with concomitant durvalumab administration, thereby employing the immune-promoting effects of radiotherapy, and determining safety, feasibility, and efficacy of this treatment.Methods/ designIn this prospective phase II clinical trial, durvalumab therapy will be combined with either conventionally fractionated (CON-group) or hypofractionated (HYPO-group) thoracic radiotherapy. A safety stop-and-go lead-in phase will assess safety of hypofractionated radiotherapy with respect to severe pneumonitis in small patient cohorts before opening full enrollment. Tumor tissue, blood and stool samples will be collected before and during the study period to investigate the immunological mechanisms responsible for checkpoint inhibitor efficacy and immune-promoting effects of radiotherapy.DiscussionPreclinical data suggests that irradiation-induced immunogenicity can be further increased if applied in a hypofractionated setting, potentially boosting the expected synergistic effect with immune checkpoint inhibition in restoring the immune anti-tumor response. If proven safe and efficient, a hypofractionated radiation schedule can provide a considerably more practicable option for the patient. Taking into consideration the intend to develop a combination treatment strategy that can be made available to patients soon after proving to be efficient and the potentially elevated toxicity of a hypofractionated radiotherapy approach, this trial was designed as a two-trials-in-one design. An accompanying translational research program is planned striving to gain insights into the tumor-host biology and to identify suitable biomarkers to predict therapy response.Trial registrationClinicaltrials.gov , NCT04351256 .
