MA14.07 - Real Life Experience with Immunotherapy in the Netherlands (ID 4689)
16:42 - 16:48 | Author(s): M. Van Den Heuvel
- Abstract
- Presentation
Background:
Randomized phase III trials have shown that the PD-1 blocking monoclonal antibody Nivolumab is effective in advanced NSCLC. Nivolumab is registered by the FDA and EMA for treatment of NSCLC. However, approval in The Netherlands was put on hold because of Nivolumab's high price per quality adjusted life year (QALY). From August 2015, Nivolumab was provided through a compassionate use program. Here we present our experience in treating NSCLC patients with Nivolumab in real life.
Methods:
Efficacy and safety of Nivolumab was assessed in patients with advanced NSCLC, previously treated with at least one line of platinum-based chemotherapy and an ECOG-PS of ≤2. Nivolumab was administered 2-weekly at a dose of 3 mg/kg intravenously. Response evaluation took place according to RECIST 1.1 at 12 and 24 weeks after start of treatment.
Results:
In the 10-month period in a single center 189 patients started treatment with Nivolumab, with a mean follow up time of 106 days after start of treatment. Mean age was 62 years (range 29–83), 57% male, 18,5% never smoked, 68% had adenocarcinoma, 20% had squamous histology and 12% were other, mixed or unspecified types. Figure 1 Twenty-four percent of patients experience immunotherapy related toxicity, most toxicities were short-term or easily manageable. No grade 5 toxicities, one grade 4 hepatitis and one grade 3 hypophysitis were observed. Hypothyroidism was most frequently observed (gr.1-2; 9,5%), followed by skin-reactions (gr.1-3; 3,8%) and colitis (gr.1-2; 3,2%). Other immune related toxicities were hepatitis (gr.1-4; 2,5%), infusion reactions (gr.1; 2,5%), pneumonitis (gr.2; 1,9%), hyperthyroidism (gr.1; 1,3%), arthritis (gr.2; 0,6%), hypophysitis (gr.3; 0,6%) and diabetes mellitus type 1 (gr.3, 0,6%).
Conclusion:
Although follow up is short and response data not yet mature, real-life efficacy and safety data from Nivolumab are comparable to phase III trial data.

MA16.03 - Global RET Registry (GLORY): Activity of RET-Directed Targeted Therapies in RET-Rearranged Lung Cancers (ID 4325)
14:26 - 14:32 | Author(s): M. Van Den Heuvel
- Abstract
- Presentation
Background:
GLORY is a global registry of patients with RET-rearranged non-small cell lung cancer (NSCLC). In order to complement ongoing prospective studies, the registry’s goal is to provide data on the efficacy of RET-directed targeted therapies administered outside the context of a clinical trial. We previously reported results from our first interim analysis (Gautschi, ASCO 2016). Following additional accrual into the registry, updated results are presented here, with a focus on an expanded efficacy analysis of various RET inhibitors.
Methods:
A global, multicenter network of thoracic oncologists identified patients with pathologically-confirmed NSCLC harboring a RET rearrangement. Molecular profiling was performed locally via RT-PCR, FISH, or next-generation sequencing. Anonymized data including clinical, pathologic, and molecular features were collected centrally and analyzed by an independent statistician. Response to RET tyrosine kinase inhibition (TKI) administered off-protocol was determined by RECIST1.1 (data cutoff date: April 15, 2016). In the subgroup of patients who received RET TKI therapy, the objectives were to determine overall response rate (ORR, primary objective), progression-free survival (PFS), and overall survival (OS).
Results:
165 patients with RET-rearranged NSCLC from 29 centers in Europe, Asia, and the USA were accrued. The median age was 61 years (range 28-89 years). The majority of patients were female (52%), never smokers (63%), with lung adenocarcinomas (98%) and advanced disease (91%). The most frequent metastasic sites were lymph nodes (82%), bone (51%) and lung (32%). KIF5B-RET was the most commonly identified fusion (70%). 53 patients received at least one RET-TKI outside of a clinical protocol, including cabozantinib (21), vandetanib (11), sunitinib (10), sorafenib (2), alectinib (2), lenvatinib (2), nintedanib (2), ponatinib (2) and regorafenib (1). In patients who were evaluable for response (n=50), the ORR was 37% for cabozantinib, 18% for vandetanib, and 22% for sunitinib. Median PFS was 3.6, 2.9, and 2.2 months and median OS was 4.9, 10.2, and 6.8 months for cabozantinib, vandetanib, and sunitinib, respectively. Responses were also observed with nintedanib and lenvatinib. Among patients who received more than one TKI (n=10), 3 partial responses were achieved after prior treatment with a different TKI.
Conclusion:
RET inhibitors are active in individual patients with RET-rearranged NSCLC, however, novel therapeutic approaches are warranted with the hope of improving current clinical outcomes. GLORY remains the largest dataset of patients with RET-rearranged NSCLC, and continues to accrue patients.

P3.02c-052 - Electronic Nose: An Early Response Biomarker for Anti-PD1 Therapy in Patients with NSCLC (ID 4528)
14:30 - 14:30 | Author(s): M. Van Den Heuvel
- Abstract
Background:
Multiple studies have shown the activity of the anti-PD(L)-1 agents in patients with advanced non-small-cell lung cancer (NSCLC). There is an urgent need to explore biomarkers that predict outcome to anti-PD-1 therapy. The electronic (e) Nose is used to analyse the exhaled gasses and is under development as a diagnostic tool for lung cancer. We aimed to determine the diagnostic accuracy of exhaled breath analysis for responders vs. non-responders to anti-PD-1 treatment in NSCLC patients.
Methods:
Patients with NSCLC who were about to receive Nivolumab, were asked to participate. At baseline and after 6 weeks of treatment exhaled breath analysis took place. Breathprints were collected in duplicate by an e-Nose positioned at the rear end of a pneumotachograph (SpiroNose) (de Vries J Breath Res 2015). RECIST 1.1 criteria were used for response evaluation at three months and six months and reported accordingly: Complete response (CR), Partial response (PR), stable disease (SD), and progressive disease (PD). Data-analysis involved signal processing, environment correction and statistics based on principal component analysis (PCA), followed by discriminant analysis (Matlab2014/SPSS20).
Results:
From August 2015 until April 2016, 56 patients participated in this trial. Forty-two patients had a response evaluation. Principal component 3 and 4 showed a significant difference (p=0.005 and p=0.001) between responders (PR and SD) and non-responders (PD) [Figure A]. Twenty-five patients had a second exhaled breath analysis after 6 weeks. Analysis showed significant differences in PC3 and PC4 between both SD vs. PR (p<0.001) and PD vs. PR (p=0.002) [Figure B].Figure 1
Conclusion:
E-Nose is able to discriminate between responders and non-responders to anti-PD-1 treatment at baseline and 6 weeks follow-up and may therefor be of great value to predict outcome.
