  • Phase I/II clinical and pharmacokinetic study evaluating a fully human monoclonal antibody against EGFr (HuMax-EGFr) in patients with advanced squamous cell carcinoma of the head and neck
  • 2007
  • Ingår i: Radiotherapy and Oncology. - : Elsevier BV. - 1879-0887 .- 0167-8140. ; 85:1, s. 24-28
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose: To assess safety, tolerability, pharmacokinetics and clinical activity of HuMax-EGFr in patients with SCCHN. Patients and methods: Twenty-eight patients with SCCHN were enrolled. The study comprised a single-dose escalation part for assessment of safety issues followed by a repeat dose extension including 4 weekly infusions at the same doses. Efficacy and metabolic response were evaluated according to RECIST by CT and FDG-PET. Results: Most frequently reported adverse event was rash. All but one event were CTC grade 1 or 2 and a dose-dependent relationship was indicated. Duration of skin reactions varied from few days to 2 months. No DLTs were observed and MTD was not reached. In the two highest dose groups, 7 of 11 patients obtained a PR or SD and 9 patients obtained metabolic PR or SD. Conclusions: HuMax-EGFr can be safety administered in doses up to 8 mg/kg, and preliminary data on tumour response are encouraging. (c) 2007 Elsevier Ireland Ltd.

  • Autoimmune antibodies and recurrence-free interval in melanoma patients treated with adjuvant interferon.
  • 2009
  • Ingår i: Journal of the National Cancer Institute. - : Oxford University Press (OUP). - 1460-2105 .- 0027-8874. ; 101:12, s. 869-77

    • BACKGROUND: Appearance of autoantibodies and clinical manifestations of autoimmunity in melanoma patients treated with adjuvant interferon (IFN)-alpha2b was reported to be associated with improved prognosis. We assessed the association of the appearance of autoantibodies after initiation of treatment with recurrence-free interval in two randomized trials that compared intermediate doses of IFN with observation for the treatment of melanoma patients. METHODS: Serum levels of anticardiolipin, antithyroglobulin, and antinuclear antibodies were determined using enzyme-linked immunosorbent assays in 187 and 356 patients in the European Organization for Research and Treatment of Cancer (EORTC) 18952 and Nordic IFN trials, respectively, immediately before and up to 3 years after random assignment. The association of the presence of at least one of the three autoantibodies with risk of recurrence was assessed by three Cox models in patients negative for all three autoantibodies at baseline (125 from the EORTC 18952 trial and 230 from the Nordic IFN trial): 1) a model that considered appearance of autoantibodies as a time-independent variable, 2) one that considered a patient autoantibody positive once a positive test for an autoantibody was obtained, and 3) a model in which the status of the patient was defined by the most recent autoantibody test. All statistical tests were two-sided. RESULTS: When treated as a time-independent variable (model 1), appearance of autoantibodies was associated with improved relapse-free interval in both trials (EORTC 18952, hazard ratio [HR] = 0.41, 95% confidence interval [CI] = 0.25 to 0.68, P < .001; and Nordic IFN, HR = 0.51, 95% CI = 0.34 to 0.76, P < .001). However, on correction for guarantee-time bias, the association was weaker and not statistically significant (model 2: EORTC 18952, HR = 0.81, 95% CI = 0.46 to 1.40, P = .44; and Nordic IFN, HR = 0.85, 95% CI = 0.55 to 1.30, P = .45; model 3: EORTC 18952, HR = 1.05, 95% CI = 0.59 to 1.87, P = .88; and Nordic IFN, HR = 0.78, 95% CI = 0.49 to 1.24, P = .30). CONCLUSIONS: In two randomized trials of IFN for the treatment of melanoma patients, appearance of autoantibodies was not strongly associated with improved relapse-free interval when correction was made for guarantee-time bias.

  • Role functioning before start of adjuvant treatment was an independent prognostic factor for survival and time to failure. A report from the Nordic adjuvant interferon trial for patients with high-risk melanoma.
  • 2013
  • Ingår i: Acta oncologica (Stockholm, Sweden). - 1651-226X. ; 52:6, s. 1086-1093
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose. To investigate the role of health-related quality of life (HRQoL) at randomization as independent prognostic factors for survival and time to failure, and to explore associations between HRQoL and treatment effects. Material and methods. In the Nordic adjuvant interferon trial, a randomized trial evaluating if adjuvant therapy with intermediate-dose IFN had the same beneficial effects on overall and disease-free survival in high-risk melanoma as high-dose IFN, 855 patients in Denmark, Finland, Norway, and Sweden were included. The EORTC QLQ-C30 questionnaire was used to assess HRQoL before randomization. Results. A total of 785 (92%) agreed to participate in the HRQoL-study and provided baseline HRQoL data. Prognostic variables included in the multivariate model were age, sex, performance status, tumor thickness, stage, and number of positive lymph nodes. Univariate analyses revealed an association between prolonged survival and age, stage/ number of metastatic lymph nodes and the HRQoL variable role functioning (p ≤ 0.01). After controlling for other prognostic factors, these variables remained independently statistically significant for survival. The univariate analyses of time to failure showed significant associations with the clinical variable stage/nodes and with the HRQoL variables physical functioning and role functioning. Adjusted multivariate analyses including the same clinical conditions as above showed statistically significant relationships between time to failure and global quality of life, physical functioning, role functioning, social functioning and fatigue (p ≤ 0.01). No interactions between HRQoL variables and treatment were found, with the exception for cognitive functioning. Conclusion. Role functioning was found to be an independent prognostic factor for time to failure and survival in patients with high-risk melanoma. Thus, also in this early stage of melanoma, HRQoL variables might be useful as important prognostic factors for time to failure and overall survival.

  • Tertiary lymphoid structures improve immunotherapy and survival in melanoma

    • Checkpoint blockade therapies that reactivate tumour-associated T cells can induce durable tumour control and result in the long-term survival of patients with advanced cancers1. Current predictive biomarkers for therapy response include high levels of intratumour immunological activity, a high tumour mutational burden and specific characteristics of the gut microbiota2,3. Although the role of T cells in antitumour responses has thoroughly been studied, other immune cells remain insufficiently explored. Here we use clinical samples of metastatic melanomas to investigate the role of B cells in antitumour responses, and find that the co-occurrence of tumour-associated CD8+ T cells and CD20+ B cells is associated with improved survival, independently of other clinical variables. Immunofluorescence staining of CXCR5 and CXCL13 in combination with CD20 reveals the formation of tertiary lymphoid structures in these CD8+CD20+ tumours. We derived a gene signature associated with tertiary lymphoid structures, which predicted clinical outcomes in cohorts of patients treated with immune checkpoint blockade. Furthermore, B-cell-rich tumours were accompanied by increased levels of TCF7+ naive and/or memory T cells. This was corroborated by digital spatial-profiling data, in which T cells in tumours without tertiary lymphoid structures had a dysfunctional molecular phenotype. Our results indicate that tertiary lymphoid structures have a key role in the immune microenvironment in melanoma, by conferring distinct T cell phenotypes. Therapeutic strategies to induce the formation of tertiary lymphoid structures should be explored to improve responses to cancer immunotherapy.

  • The prognostic role of blood lymphocyte subset distribution in patients with resected high-risk primary or regionally metastatic melanoma.
  • 2007
  • Ingår i: Journal of immunotherapy (Hagerstown, Md. : 1997). - 1524-9557. ; 30:7, s. 773-9

    • The aim of this study was to investigate whether the profile of peripheral blood lymphocyte subsets of patients with high-risk malignant melanoma is associated with prognosis. Blood samples were systematically obtained from 31 patients with high-risk melanoma eligible for the Nordic Melanoma Cooperative Group adjuvant interferon study. The frequencies of peripheral blood lymphocyte subsets were monitored by flow cytometry using CD3, CD4, CD8, CD56, and CD69 monoclonal antibodies. Patients with low proportions of CD3+CD4+CD69+ cells and of CD3+CD56+ cells before treatment had an improved disease-free survival compared to those with high proportions [77.7 vs. 16.8 mo, hazard ratio (HR) 0.25, confidence interval (CI) 0.09-0.71, P=0.005 and 77.2 vs. 16.0 mo, HR: 0.25, CI 0.086-0.73, P=0.001, respectively]. Low pretreatment levels of these cell populations also correlated with a better overall survival (79.2 vs. 22.6 mo, HR: 0.17, CI 0.05-0.52, P=0.0005 and 78.2 vs. 21.4 mo, HR: 0.2, CI 0.07-0.59, P=0.001, respectively). In the multivariate analysis both the pretreatment proportion of CD3+CD4+CD69+ cells (P=0.01, HR: 0.21, CI 0.07-0.67) and CD3+CD56+ cells (P=0.01, HR: 0.22, CI 0.062-0.65) were independent prognostic factors for overall survival. Our data show that both the proportions of CD3+CD4+CD69+ cells and of CD3+CD56+ cells seem to have a prognostic potential in the natural course of melanoma. These results need to be confirmed in larger studies.

  • Selumetinib Plus Adjuvant Radioactive Iodine in Patients with High-Risk Differentiated Thyroid Cancer : A Phase III, Randomized, Placebo-Controlled Trial (ASTRA)
  • 2022
  • Ingår i: Journal of Clinical Oncology. - 0732-183X. ; 40:17, s. 1870-1878
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSESelumetinib can increase radioactive iodine (RAI) avidity in RAI-refractory tumors. We investigated whether selumetinib plus adjuvant RAI improves complete remission (CR) rates in patients with differentiated thyroid cancer (DTC) at high risk of primary treatment failure versus RAI alone.METHODSASTRA (ClinicalTrials.gov identifier: NCT01843062) is an international, phase III, randomized, placebo-controlled, double-blind trial. Patients with DTC at high risk of primary treatment failure (primary tumor > 4 cm; gross extrathyroidal extension outside the thyroid gland [T4 disease]; or N1a/N1b disease with ≥ 1 metastatic lymph node(s) ≥ 1 cm or ≥ 5 lymph nodes [any size]) were randomly assigned 2:1 to selumetinib 75 mg orally twice daily or placebo for approximately 5 weeks (no stratification). On treatment days 29-31, recombinant human thyroid-stimulating hormone (0.9 mg)-stimulated RAI (131I; 100 mCi/3.7 GBq) was administered, followed by 5 days of selumetinib/placebo. The primary end point (CR rate 18 months after RAI) was assessed in the intention-to-treat population.RESULTSFour hundred patients were enrolled (August 27, 2013-March 23, 2016) and 233 randomly assigned (selumetinib, n = 155 [67%]; placebo, n = 78 [33%]). No statistically significant difference in CR rate 18 months after RAI was observed (selumetinib n = 62 [40%]; placebo n = 30 [38%]; odds ratio 1.07 [95% CI, 0.61 to 1.87]; P =.8205). Treatment-related grade ≥ 3 adverse events were reported in 25/154 patients (16%) with selumetinib and none with placebo. The most common adverse event with selumetinib was dermatitis acneiform (n = 11 [7%]). No treatment-related deaths were reported.CONCLUSIONPostoperative pathologic risk stratification identified patients with DTC at high risk of primary treatment failure, although the addition of selumetinib to adjuvant RAI failed to improve the CR rate for these patients. Future strategies should focus on tumor genotype-tailored drug selection and maintaining drug dosing to optimize RAI efficacy.

  • Vandetanib in locally advanced or metastatic differentiated thyroid cancer: a randomised, double-blind, phase 2 trial
  • 2012
  • Ingår i: The Lancet Oncology. - 1474-5488. ; 13:9, s. 897-905
  • Tidskriftsartikel (refereegranskat)abstract
    • Background No effective standard treatment exists for patients with radioiodine-refractory, advanced differentiated thyroid carcinoma. We aimed to assess efficacy and safety of vandetanib, a tyrosine kinase inhibitor of RET, VEGFR and EGFR signalling, in this setting. Methods In this randomised, double-blind, phase 2 trial, we enrolled adults (aged >= 18 years) with locally advanced or metastatic differentiated thyroid carcinoma (papillary, follicular, or poorly differentiated) at 16 European medical centres. Eligible patients were sequentially randomised in a 1: 1 ratio with a standard computerised scheme to receive either vandetanib 300 mg per day (vandetanib group) or matched placebo (placebo group), balanced by centre. The primary endpoint was progression-free survival (PFS) in the intention-to-treat population based on investigator assessment. This study is registered with ClinicalTrials.gov, number NCT00537095. Findings Between Sept 28, 2007, and Oct 16, 2008, we randomly allocated 72 patients to the vandetanib group and 73 patients to the placebo group. By data cutoff (Dec 2, 2009), 113 (78%) patients had progressed (52 [72%] patients in the vandetanib group and 61 [84%] in the placebo group) and 40 (28%) had died (19 [26%] patients in the vandetanib group and 21 [29%] in the placebo group). Patients who received vandetanib had longer PFS than did those who received placebo (hazard ratio [HR] 0.63, 60% CI 0.54-0.74; one-sided p=0.008): median PFS was 11.1 months (95% CI 7.7-14.0) for patients in the vandetanib group and 5.9 months (4.0-8.9) for patients in the placebo group. The most common grade 3 or worse adverse events were QTc prolongation (ten [14%] of 73 patients in the vandetanib group vs none in the placebo group), diarrhoea (seven [10%] vs none), asthenia (five [7%] vs three [4%]), and fatigue (four [5%] vs none). Two patients in the vandetanib group and one in the placebo group died from treatment-related serious adverse events (haemorrhage from skin metastases and pneumonia in the vandetanib group and pneumonia in the placebo group). Interpretation Vandetanib is the first targeted drug to show evidence of efficacy in a randomised phase 2 trial in patients with locally advanced or metastatic differentiated thyroid carcinoma. Further investigation of tyrosine-kinase inhibitors in this setting is warranted.

    • Matrix metalloproteinases (MMPs) are important enzymes in tissue turnover and various inflammatory processes. In this study, it was evaluated whether serum MMP-8 can predict the response to adjuvant interferon alfa-2b (IFN-α) therapy in patients with operated high-risk cutaneous melanoma. Pre-treatment sera from 460 patients with stage IIB-IIIC melanoma were analyzed for MMP-8. The patients were randomized after surgery to adjuvant IFN-α for 12 or 24 months (n = 313) or observation only (n = 147). The median serum MMP-8 level was used to classify the patients into a low MMP-8 (n = 232) and a high MMP-8 (n = 228) group. In the high MMP-8 subgroup, IFN-α therapy significantly improved relapse-free survival (RFS). RFS was 36.8 months in patients with high MMP-8 levels receiving IFN-α therapy, whereas RFS for those with high MMP-8 levels with observation only was 10.6 months (P = 0.027). Median overall survival for patients with high MMP-8 and observation only was 36.7 versus 71.7 months in those receiving IFN-α (P = 0.13). In a multivariate model, IFN-α therapy was a significant predictor of favorable RFS (HR 0.74; 95 % CI 0.55-0.99; P = 0.048), after adjustment for pre-treatment MMP-8 (HR 1.17; 95 % CI 0.88-1.55; P = 0.28), gender (HR 1.16; 95 % CI 0.86-1.56; P = 0.32), age (HR 1.00; 95 % CI 1.00-1.02; P = 0.12), ulceration (HR 1.09; 95 % CI 0.81-1.46; P = 0.58), and the presence of node metastases (HR 1.36; 95 % CI 1.17-1.58; P
