This is a summary of a research study (known as a clinical trial) called CROWN. The study tested two medicines called lorlatinib and crizotinib in participants with untreated non-small cell lung cancer that had spread to other parts of their body. All those who took part had changes in a gene called ALK, which is involved in cell growth. In total, 296 participants from 23 countries took part. Half the participants took lorlatinib and half took crizotinib. After participants started taking lorlatinib or crizotinib, they were checked regularly to see if their tumors had grown or spread to other parts of their body (known as tumor progression) and to monitor any side effects. After 1 year of treatment, the participants who took lorlatinib were twice as likely to be alive with no tumor growth as the participants who took crizotinib. More participants who took lorlatinib had cancer that shrank (76%) compared with the participants who took crizotinib (58%). This was also true of the participants whose cancer had spread to their brain. The most common side effects in participants who took lorlatinib were increases in the amount of cholesterol and triglycerides (a type of fat) in their blood, swelling, weight gain, nerve damage, unclear thoughts, and diarrhea. Among the participants who took crizotinib, the most common side effects were diarrhea, feeling like you want to throw up, sight problems, swelling, vomiting, changes in liver function, and feeling tired. Overall, the CROWN study showed that fewer participants with advanced ALK+ non-small cell lung cancer died or had tumor growth with lorlatinib compared with crizotinib treatment.

Treatment Benefits

Abstract Purpose To describe symptoms and side effects experienced by patients with advanced non-small cell lung cancer (NSCLC), assess how patients allocate sensations (i.e. symptoms or side effects) to either the disease or its treatment, and evaluate how patients balance side effects with treatment benefits. Methods Qualitative sub-studies were conducted as part of two clinical trials in patients treated for advanced NSCLC (AURA [NCT01802632]; ARCTIC [NCT02352948]). Results Interviews were conducted with 23 patients and 19 patients in the AURA and ARCTIC sub-studies, respectively. The most commonly experienced symptoms/side effects were respiratory (81% of patients), digestive (76%), pain and discomfort (76%), energy-related (71%), and sensory (62%). Patients identified a sensation as a treatment side effect if they had not experienced it before, if there was a temporal link between the sensation and receipt of treatment, and/or if their doctors consistently told or asked them about it in relation to side effects. Themes that emerged when patients talked about their cancer treatment and its side effects related to the serious nature of their advanced disease and their treatment expectations. Patients focused on treatment benefits, wanting a better quality of life, being hopeful, not really having a choice, and not thinking about side effects. Conclusions In these two qualitative sub-studies, patients with advanced NSCLC valued the benefits of their treatment regardless of side effects that they experienced. Patients weighed their options against the seriousness of their disease and expressed their willingness to tolerate their side effects in return for receiving continued treatment benefits.

Background Advanced non-small-cell lung cancer (nsclc) represents a major health issue globally. Systemic treatment decisions are informed by clinical trials, which, over years, have improved the survival of patients with advanced nsclc. The applicability of clinical trial results to the broad lung cancer population is unclear because strict eligibility criteria in trials generally select for optimal patients.Methods We performed a retrospective chart review of all consecutive patients with advanced nsclc seen in outpatient consultation at our academic institution between September 2009 and September 2012, collecting data about patient demographics and cancer characteristics, treatment, and survival from hospital and pharmacy records. Two sets of arbitrary trial eligibility criteria were applied to the cohort. Scenario A stipulated Eastern Cooperative Oncology Group performance status (ecog ps) 0–1, no brain metastasis, creatinine less than 120 μmol/L, and no second malignancy. Less-strict scenario B stipulated ecog ps 0–2 and creatinine less than 120 μmol/L. We then used the two scenarios to analyze treatment and survival of patients by trial eligibility status.Results The 528 included patients had a median age of 67 years, with 55% being men and 58% having adenocarcinoma. Of those 528 patients, 291 received at least 1 line of palliative systemic therapy. Using the scenario A eligibility criteria, 73% were trial-ineligible. However, 46% of “ineligible” patients actually received therapy and experienced survival similar to that of the “eligible” treated patients (10.2 months vs. 11.6 months, p = 0.10). Using the scenario B criteria, only 35% were ineligible, but again, the survival of treated patients was similar in the ineligible and eligible groups (10.1 months vs. 10.9 months, p = 0.57).Conclusions Current trial eligibility criteria are often strict and limit the enrolment of patients in clinical trials. Our results suggest that, depending on the chosen drug, its toxicities and tolerability, eligibility criteria could be carefully reviewed and relaxed.

Abstract In order to optimize patient-tailored chemotherapy, a non-small-cell lung cancer (NSCLC)-liver metastasis patient-derived tumor xenograft (PDTX) model is developed. Computed tomography (CT)-guided NSCLC percutaneous biopsy was subcutaneously inoculated into the flank of non-obese diabetic/severe combined immunodeficiency (NOD/SCID) female mice (PDTX F1) and allowed to reach 500 mm3 volume. Then, the tumors were re-transplanted into Balb/c nude mice and liver metastasis was confirmed (PDTX F2), which were further assigned into doxorubicin (DOX), docetaxel (DTX), and non-treatment control group. H&E staining and Keratin 20 (CK20) staining were applied to determine the consistency of PDTX models and primary tumors. Tumor growth curve, body weight, and the expression of p65 nuclear factor (NF)-κB and the secretion of interferon (IFN)-γ were investigated. The successive transplant procedure can induce the NSCLC-liver metastasis PDTX model, and morphological and structural characteristics of PDTX models (F2) were in accordance with primary tumors. DOX and DTX could delay tumor growth, activate the NF-κB pathway, and promote IFN-γ secretion in the PDTX models. The NSCLC-liver metastasis PDTX model is established and provides a powerful mean to assess chemotherapeutic efficacy.
