RESUMO

BACKGROUND: Psoriasis vulgaris is commonly treated with topical corticosteroids and vitamin D analogues. Although potent and super-potent topical corticosteroids are very effective at clearing psoriasis, with short-term reactive treatment durations, symptoms usually recur after treatment discontinuation, necessitating long-term disease management strategies. A foam formulation of calcipotriol and betamethasone dipropionate (Cal/BD foam), consisting of calcipotriol 50 µg/g and betamethasone dipropionate 0.5 mg/g, is approved for the daily treatment of psoriasis for up to 4 weeks. Here, we describe a clinical trial protocol for evaluating the long-term safety and efficacy of twice-weekly Cal/BD foam as a proactive topical maintenance therapy for plaque psoriasis for up to 52 weeks. OBJECTIVE: The aim of this trial was to evaluate the safety and efficacy of Cal/BD foam when applied twice weekly for up to 52 weeks as proactive maintenance therapy, with the goal of preventing or delaying disease relapse as long as possible while minimizing adverse effects. METHODS: Once-daily Cal/BD foam treatment responders from an initial 4-week open-label period were randomized to receive Cal/BD foam or foam vehicle applied to previously cleared plaques twice weekly for up to 52 weeks. In case of relapse, affected subjects in either group received rescue therapy with once-daily Cal/BD foam for 4 weeks on active areas. Thus, the trial (NCT02899962) compared the long-term use of Cal/BD foam in a proactive approach with a conventional, reactive approach. PLANNED OUTCOMES: Efficacy endpoints included the time to first relapse, the number of relapse-free days, and the number of relapses during the maintenance phase. Safety assessments included adverse events, incidence of rebound, local safety and tolerability scores, and effects on calcium metabolism and hypothalamic-pituitary-adrenal axis function. TRIAL REGISTRATION: ClinicalTrials.gov identifier, NCT02899962.

RESUMO

BACKGROUND: Topical psoriasis treatment relies on a reactive, rather than long-term proactive, approach to disease relapse. OBJECTIVE: Assess long-term efficacy and safety of proactive psoriasis management with twice-weekly calcipotriene 0.005%/betamethasone dipropionate 0.064% (Cal/BD) foam. METHODS: Phase III trial (NCT02899962) included a 4-week open-label lead-in phase (Cal/BD foam once-daily) and 52-week, randomized, double-blind, maintenance phase. 545 patients achieved treatment success PGA 'clear'/'almost clear', ≥2-grade improvement from baseline) and were randomized to 'proactive' management (Cal/BD foam; n = 272) or 'reactive' management (vehicle foam; n = 273) twice-weekly, with rescue treatment of Cal/BD foam once-daily for 4 weeks upon relapse. Primary endpoint: time to first relapse (PGA ≥'mild'). RESULTS: 251 (46.1%) randomized patients completed the trial. Median time to first relapse: 56 days (proactive), 30 days (reactive). Patients in the proactive group had an additional 41 days in remission compared with the reactive group over 1 year (P < 0.001). Number of relapses per year of exposure: 3.1 (proactive), 4.8 (reactive). Cal/BD foam was well tolerated. LIMITATIONS: Maintenance phase dropout rate (53.9%) was within the expected range but provides challenges in statistical analysis. CONCLUSION: Long-term proactive management with Cal/BD foam demonstrated superior efficacy versus reactive management.

RESUMO

INTRODUCTION: Clinical trials have shown that psoriasis patients who achieve complete skin clearance are more likely to report no impairment in health-related quality of life (HRQoL) and no psoriasis symptoms versus patients who achieve almost complete skin clearance. However, real-world data are lacking. The objective of this study was to estimate the real-world proportion of moderate-to-severe psoriasis patients on biologic treatment who achieved a Psoriasis Symptom Inventory (PSI) total score of 0 (PSI 0; no symptoms) and a Dermatology Life Quality Index (DLQI) score of 0/1 (DLQI 0/1; no impact on HRQoL), and to study the relationship between patient-reported symptoms and HRQoL versus physician-reported psoriasis severity (Psoriasis Area and Severity Index [PASI]). METHODS: The PSO-BIO-REAL study was a multinational, prospective, real-world, non-interventional study that included patients aged ≥ 18 years with moderate-to-severe plaque psoriasis who had initiated biologic therapy (either biologic-naïve or had switched biologics [biologic-experienced]). Psoriasis symptoms were evaluated using the PSI, and HRQoL was assessed using the DLQI. Assessments were conducted at baseline and at 6 and 12 months after initiating biologic treatment. Associations between PSI and DLQI with PASI were evaluated using Spearman correlation coefficients. Post-hoc analyses evaluated individual PSI items and the association to PASI response, DLQI and PSI by index biologic. RESULTS: At 12 months, 25.5% of patients achieved PSI 0, and 51.2% achieved DLQI 0/1, with greater proportions achieving these scores among biologic-naïve than among biologic-experienced patients. There was a moderate-to-strong correlation between PSI and DLQI scores and PASI scores, with 64.8% of patients with absolute PASI 0 and 19.4% with absolute PASI > 0 ≤ 2 achieving PSI 0 (6 and 12 months pooled). Achievement of response varied by index biologic. CONCLUSION: This study demonstrates that in a real-world setting patients' QoL improves with skin clearance. The results also demonstrate that the correlation between skin clearance and improvements in HRQoL (DLQI) and psoriasis symptoms (PSI) is not complete, which highlights the importance of considering both patient- and physician-reported outcomes in the assessment of psoriasis treatment outcomes.

RESUMO

INTRODUCTION: Patients with plaque psoriasis often have nail psoriasis, which is difficult to treat. Ixekizumab (IXE) and ustekinumab (UST) are biologics with established efficacy in nail psoriasis. We present post hoc data from a head-to-head trial of IXE and UST (IXORA-S) to examine the efficacy in nail psoriasis in patients with moderate-to-severe plaque psoriasis over 52 weeks. METHODS: In IXORA-S, randomised patients received IXE (N = 136) or UST (N = 166) per label for 52 weeks. Eighty-four (61.8%) and 105 (63.3%) of the patients treated with IXE or UST, respectively, had baseline fingernail psoriasis (Nail Psoriasis Severity Index [NAPSI] > 0); of these, 54 (64.3%) and 63 (60.0%) patients, respectively, had significant baseline fingernail psoriasis (defined as NAPSI ≥ 16 with ≥ 4 fingernails involved). The proportion of patients achieving NAPSI = 0, a NAPSI score change from baseline and correlations in Psoriasis Area of Severity Index (PASI) and NAPSI improvement over 52 weeks were examined. RESULTS: Progressive improvement occurred in both treatment groups over 52 weeks. Statistically significantly more patients achieved NAPSI = 0 with IXE versus UST by week 16-20, and the proportions continued to increase through week 52 among patients with baseline nail psoriasis (61.9 vs. 28.6%, respectively; P < 0.001), including those with significant nail psoriasis (57.4 vs. 17.5%, respectively; P < 0.001). Similar results were observed for NAPSI score improvement from baseline to week 52. Interestingly, the presence of nail psoriasis was associated with lower skin response with UST but not with IXE. CONCLUSIONS: Ixekizumab was superior to UST in the clearance of nail psoriasis, with earlier improvement continued through 52 weeks regardless of baseline nail severity.

RESUMO

BACKGROUND: Prurigo nodularis is a chronic pruritic skin disease with multiple nodular skin lesions. Nemolizumab is a monoclonal antibody targeting the interleukin-31 receptor, which is involved in the pathogenesis of prurigo nodularis. METHODS: We conducted a 12-week, randomized, double-blind, phase 2 trial of nemolizumab (at a dose of 0.5 mg per kilogram of body weight) administered subcutaneously at baseline, week 4, and week 8, as compared with placebo, in patients with moderate-to-severe prurigo nodularis and severe pruritus. Moderate-to-severe prurigo nodularis was defined as 20 or more nodules, and severe pruritus was defined as a mean score of at least 7 for the worst daily intensity of pruritus on the numerical rating scale (scores range from 0 [no itch] to 10 [worst itch imaginable]). The primary outcome was the percent change from baseline in the mean peak score for pruritus on the numerical rating scale at week 4. Secondary outcomes included additional measures of itching and disease severity. Safety assessments were performed through week 18. RESULTS: A total of 70 patients were randomly assigned in a 1:1 ratio to receive nemolizumab (34 patients) or placebo (36). The initial pruritus score on the numerical rating scale was 8.4 in each group. At week 4, the peak pruritus score on the numerical rating scale was reduced from baseline by 4.5 points (change, -53.0%) in the nemolizumab group, as compared with a reduction of 1.7 points (change, -20.2%) in the placebo group (difference, -32.8 percentage points; 95% confidence interval, -46.8 to -18.8; P<0.001). Results for secondary outcomes were in the same direction as for the primary outcome. Nemolizumab was associated with gastrointestinal symptoms (abdominal pain and diarrhea) and musculoskeletal symptoms. CONCLUSIONS: Nemolizumab resulted in a greater reduction in pruritus and severity of skin lesions than placebo in patients with prurigo nodularis but was associated with adverse events. Larger and longer trials are needed to determine the durability and safety of nemolizumab for the treatment of prurigo nodularis. (Funded by Galderma; ClinicalTrials.gov number, NCT03181503.).

RESUMO

BACKGROUND: Scientific rationale and encouraging first clinical results suggest the interest of using apremilast for treating vitiligo. OBJECTIVE: This study aimed to compare the efficacy of apremilast in combination therapy with narrowband (NB)-UVB versus placebo and NB-UVB treatment for repigmentation in patients with nonsegmental vitiligo. DESIGN: This was a 52-week prospective randomized placebo-controlled study. PARTICIPANTS: Adult patients with vitiligo participated. INTERVENTIONS: Group A received, in addition to phototherapy, apremilast at the label dosage, and group B received placebo. After 24 weeks, patients who responded (decreased Vitiligo Area Scoring Index >30%) were rerandomized to receive apremilast or placebo, combined with twice-weekly NB-UVB for 24 additional weeks. Main outcome and measure: The primary outcome measure was the comparison between the two groups of the Vitiligo Area Scoring Index score at 24 weeks. RESULTS: Eighty patients were randomized (40 in each group). After 24 weeks, the mean Vitiligo Area Scoring Index score decreased from 23.63 to 19.49 (P = 0.011) in the apremilast + UVB group and from 21.57 to 15.25 (P < 0.0001) in the placebo + UVB group. The difference between the two groups was not statistically significant (P = 0.18). No statistically significant differences were observed between the two groups after an additional 24 weeks of treatment. CONCLUSIONS AND RELEVANCE: Apremilast does not bring any benefit to NB-UVB for treating vitiligo.

RESUMO

Importance: The dupilumab regimen of 300 mg every 2 weeks is approved for uncontrolled, moderate to severe atopic dermatitis (AD). Objective: To assess the efficacy and safety of different dupilumab regimens in maintaining response after 16 weeks of initial treatment. Design, Setting, and Participants: The Study to Confirm the Efficacy and Safety of Different Dupilumab Dose Regimens in Adults With Atopic Dermatitis (LIBERTY AD SOLO-CONTINUE) was a randomized, double-blind, phase 3 clinical trial conducted from March 25, 2015, to October 18, 2016, at 185 sites in North America, Europe, Asia, and Japan. Patients with moderate to severe AD who received dupilumab treatment and achieved an Investigator's Global Assessment score of 0 or 1 or 75% improvement in Eczema Area and Severity Index scores (EASI-75) at week 16 in 2 previous dupilumab monotherapy trials (LIBERTY AD SOLO 1 and 2) were rerandomized in SOLO-CONTINUE. After completing SOLO-CONTINUE, patients were followed up for up to 12 weeks or enrolled in an open-label extension. Data were analyzed from December 5 to 12, 2016. Interventions: High-responding patients treated with dupilumab in SOLO were rerandomized 2:1:1:1 to continue their original regimen of dupilumab, 300 mg, weekly or every 2 weeks or to receive dupilumab, 300 mg, every 4 or 8 weeks or placebo for 36 weeks. Main Outcomes and Measures: Percentage change in EASI score from baseline during the SOLO-CONTINUE trial, percentage of patients with EASI-75 at week 36, and safety. Results: Among the 422 patients (mean [SD] age, 38.2 [14.5] years; 227 [53.8%] male), continuing dupilumab treatment once weekly or every 2 weeks maintained optimal efficacy, with negligible change in percent EASI improvement from SOLO 1 and 2 baseline during the SOLO-CONTINUE trial (-0.06%; P < .001 vs placebo); percent change with the other regimens dose-dependently worsened (dupilumab every 4 weeks, -3.84%; dupilumab every 8 weeks, -6.84%; placebo, -21.67%). More patients taking dupilumab weekly or every 2 weeks (116 of 162 [71.6%]; P < .001 vs placebo) maintained EASI-75 response than those taking dupilumab every 4 weeks (49 of 84 [58.3%]) or every 8 weeks (45 of 82 [54.9%]) or those taking placebo (24 of 79 [30.4%]). Overall adverse event incidences were 70.7% in the weekly or every 2 weeks group, 73.6% in the every 4 weeks group, 75.0% in the every 8 weeks group, and 81.7% in the placebo group. Treatment groups had similar conjunctivitis rates. Treatment-emergent antidrug antibody incidence was lower with more frequent dupilumab dose regimens (11.3% in the placebo group and 11.7%, 6.0%, 4.3%, and 1.2% in the dupilumab every 8 weeks, every 4 weeks, every 2 weeks, and weekly groups, respectively). Conclusions and Relevance: In this trial, continued response over time was most consistently maintained with dupilumab administered weekly or every 2 weeks. Longer dosage intervals and placebo resulted in a diminution of response for both continuous and categorical end points. No new safety signals were observed. The approved regimen of 300 mg of dupilumab every 2 weeks is recommended for long-term treatment. Trial Registration: ClinicalTrials.gov identifier: NCT02395133.

RESUMO

A 49-year-old patient with metastatic melanoma was treated with nivolumab (Opdivo). An early F-FDG PET/CT after 2 cycles showed a progressive metabolic disease. A 4-month optimal follow-up F-FDG PET/CT showed a complete metabolic response. The treatment was stopped after 22 cycles because of immunotherapy-related pneumonitis. After discontinuation of treatment, PET/CT examinations demonstrated a metabolic complete remission during 2 years. The metabolic pattern on early PET was suggestive of pseudoprogression, which is a rare phenomenon reflecting an activation of inflammatory cells within the tumor microenvironment causing lesions to increase in size and to accumulate FDG until a sufficient immune response is developed.

RESUMO

BACKGROUND: Phase III clinical trials of biotherapies for childhood psoriasis are designed for a selected population, which can differ from real-life patients. OBJECTIVE: Our objective was to assess the proportion of children with psoriasis that received biotherapy in the biological treatments for pediatric psoriasis (BiPe) cohort that would be excluded from phase III clinical trials of these treatments. METHODS: Data concerning initiation of the first biotherapy from all patients included in the BiPe cohort were analyzed. Ineligibility was assessed after applying the exclusion criteria used in the principal phase III trials of etanercept, adalimumab, and ustekinumab for childhood psoriasis. RESULTS: Of the 134 patients included, 73 (54.5%) were ineligible for at least one randomized controlled trial based on one or more exclusion criteria. Amongst the 63 children treated with etanercept, 35 (55.5%) were ineligible: 22 because of the type of psoriasis, 12 because of concomitant treatment, and six because of psoriasis severity based on psoriasis assessment severity index (PASI) and physician global assessment (PGA) scores (PASI < 12 and PGA < 3). Amongst the 44 children treated with adalimumab, 32 (72.7%) were ineligible: 17 because of the clinical type of psoriasis, 12 because of psoriasis severity (PASI < 20 and PGA < 4), and seven because of concomitant treatment. Amongst the 27 children patients treated with ustekinumab, 12 (44.4%) were ineligible: eight because of psoriasis severity (PASI < 12 and PGA < 3), five because of the clinical type of psoriasis, and one because of concomitant treatment. Drug survival and the frequency of serious adverse events did not differ between eligible and ineligible patients. CONCLUSION: The majority of children treated with biotherapies in real-life practice differ from those in phase III trials, most commonly because of the clinical type of their psoriasis, the disease severity being lower than required and the use of prior or concomitant psoriasis treatment. Efficacy and safety results from phase III clinical trials in selected populations may not sufficiently reflect what is seen in real life, thus results from real-life cohort studies are necessary.

RESUMO

BACKGROUND: Patients with epidermal nevi strongly demand cosmetic improvement. Laser treatment appears appealing and is frequently used in clinical practice. Nevertheless, large series with long-term follow-up are missing, preventing definitive conclusions about its real benefit. OBJECTIVE: To evaluate the long-term effectiveness and safety of lasers for epidermal nevi. METHODS: Bicentric, retrospective, cohort study, including all patients treated with a laser for an epidermal nevus with more than a 1-year follow-up. RESULTS: Seventy patients were treated for different types of epidermal nevi, mostly with ablative lasers: 23 verrucous epidermal nevi, 16 nevi sebaceous, 26 Becker nevi, 2 inflammatory linear verrucous epidermal nevi, 1 smooth-muscle hamartoma, 1 rounded and velvety epidermal nevus, and 1 nevus lipomatosus superficialis. The follow-up period was a median of 37 months (range, 12-127 months). Better results, fewer recurrences, and higher patient satisfaction were noted in treatments for verrucous epidermal nevi than for nevi sebaceous. Q-switched lasers failed to show any degree of improvement in almost all patients with Becker nevus. LIMITATIONS: The retrospective nature of the study. CONCLUSIONS: Ablative lasers can treat verrucous epidermal nevi with good long-term esthetic results but have limited long-term efficacy for nevus sebaceous. Q-switched lasers failed to improve Becker nevi.

RESUMO

Importance: The prognosis of advanced melanoma has been greatly improved by new therapeutic agents and clinicians rely on dynamic signals to drive their therapeutic choices. Although the kinetics of metastatic disease seem to be correlated with survival, progression of the localized disease is not predictable. Objective: To assess whether progression of metastatic disease is associated with the time to the first distant recurrence of melanoma. Design, Setting, and Participants: This study was conducted from March 1, 2013, to September 1, 2017, among 638 adults with unresectable stage III or IV melanoma within the French multicentric prospective cohort MelBase. Patients treated with first-line immunotherapies, targeted therapies, or chemotherapy were included. Patients with unknown primary or de novo metastatic melanoma were not included. Data were analyzed from March 1, 2013, to December 1, 2017. Main Outcomes and Measures: The date of primary excision and time to first distant recurrence, progression-free survival, and overall survival were collected. Cox proportional hazards regression models were planned to assess the association between time to first distant recurrence and progression-free survival or overall survival, which was evaluated in terms of hazard ratio (HR). Time to recurrence was analyzed both as a continuous and categorical variable (<12 months, 12-24 months, and >24 months). Results: A total of 638 patients (272 women and 366 men; median age, 64 years [interquartile range, 52-73 years]) were included in the study. The median time from primary excision to first distant recurrence was 25 months (interquartile range, 12-55 months). There was no evidence of association of the time to recurrence with progression-free survival, both when analyzed as a continuous variable (HR, 0.99; 95% CI, 0.99-1.01) or after categorization (12-24 months: HR, 0.75; 95% CI, 0.56-1.02; >24 months: HR, 0.62; 95% CI; 0.47-1.01). There was no evidence of association of the time to recurrence with overall survival, both when analyzed as a continuous variable (HR, 0.99; 95% CI, 0.98-1.02) or after categorization (12-24 months: HR, 0.76; 95% CI, 0.54-1.07; >24 months: HR, 0.61; 95% CI, 0.54-1.03). Those results remained nonsignificant after stratification by treatment. Conclusions and Relevance: In the MelBase cohort, time to recurrence of metastatic melanoma appears not to be associated with progression-free survival or overall survival.

RESUMO

BACKGROUND: Melanoma brain metastases (MBMs) are historically associated with poor prognosis. Radiation therapy is conventionally associated with a high local control rate. Development of targeted therapy and immunotherapy has improved overall survival (OS) and intracranial response rate, but about 50% of patients failed to respond to these novel therapies. The objective of this study was to assess the impact of combined radiotherapy (cRT) on overall survival in a large multicenter real-life prospective cohort of patients with MBM treated with immunotherapy or targeted therapy. PATIENTS AND METHODS: Clinical data from 262 patients with MBM were collected via MelBase, a French multicentric biobank prospectively enrolling unresectable stage III or IV melanoma. Two groups were defined: patients receiving cRT (cRT group) or not receiving cRT (no-cRT group). Primary end-point was OS. Propensity score weighting was used to correct for indication bias. RESULTS: Among the 262 patients, 93 (35%) received cRT (cRT group). The patients were treated with immunotherapy in 69% and 60% and with targeted therapy in 31% and 40% of the cRT and no-cRT groups, respectively. With a median follow-up of 6.9 months, median OS was 16.8 months and 6.9 months in the cRT and no-cRT groups, respectively. After propensity score weighting, cRT was associated with longer OS (hazard ratio = 0.6, 95% confidence interval: 0.4-0.8; p=0.007). Median OS after ponderation was 15.3 months and 6.2 months in the cRT and no-cRT groups, respectively. CONCLUSION: This study shows that cRT may be associated with a significant decrease of 40% in the risk of death in patients with MBM treated with systemic therapy.

RESUMO

BACKGROUND: Dupilumab is the first biologic available to treat atopic dermatitis (AD). Its effectiveness and safety were demonstrated in clinical trials. OBJECTIVE: We sought to assess the effectiveness and safety of dupilumab in adults with AD in a real-life French multicenter retrospective cohort. METHODS: We included patients treated during March 2017-April 2018. Efficacy outcomes, including Scoring Atopic Dermatitis (SCORAD) and Eczema Area and Severity Index (EASI) scores, were collected at baseline and 3 months when available. Adverse events (AEs) were recorded at follow-up. RESULTS: We included 241 patients. The median ± interquartile range (IQR) follow-up time was 3.8 ± 3.7 months. A ≥75% improvement in SCORAD was achieved in 27 of 163 (16.6%) patients, and a ≥75% improvement in EASI was achieved in 40 of 82 (48.8%) patients. The median SCORAD and EASI scores at 3 months were significantly lower than those at baseline (SCORAD ± IQR, 25 ± 21 vs 56 ± 27.4, P < 10-9 and EASI ± IQR, 4.1 ± 6.8 vs 17.9 ± 15.4, P < 10-9, respectively). Conjunctivitis was reported in 84 of 241 (38.2%) patients. The proportion with eosinophilia (>500 cells/mm3) during follow-up (57%) was higher than that at baseline (33.7%) (n = 172, P < 10-6). Dupilumab was stopped in 42 cases; 27 patients stopped because of AEs. LIMITATIONS: No control group, missing data. CONCLUSION: This real-life study demonstrated a similar dupilumab effectiveness as that seen in clinical trials, but it also revealed a higher frequency of conjunctivitis and eosinophilia.

RESUMO

Inflammatory caspases, activated within the inflammasome, are responsible for the maturation and secretion of IL-1ß/IL-18. Although their expression in psoriasis was shown several years ago, little is known about the role of inflammatory caspases in the context of psoriasis. Here, we confirmed that caspases 1, 4, and 5 are activated in lesional skin from psoriasis patients. We showed in three psoriasis-like models that inflammatory caspases are activated, and accordingly, caspase 1/11 invalidation or pharmacological inhibition by Ac-YVAD-CMK (i.e., Ac-Tyr-Val-Ala-Asp-chloromethylketone) injection induced a decrease in ear thickness, erythema, scaling, inflammatory cytokine expression, and immune cell infiltration in mice. We observed that keratinocytes were primed to secrete IL-1ß when cultured in conditions mimicking psoriasis. Generation of chimeric mice by bone marrow transplantation was carried out to decipher the respective contribution of keratinocytes and/or immune cells in the activation of inflammatory caspases during psoriasis-like inflammatory response. Our data showed that the presence of caspase 1/11 in the immune system is sufficient for a fully inflammatory response, whereas the absence of caspase 1/11 in keratinocytes/fibroblasts had no impact. In summary, our study indicates that inflammatory caspases activated in immune cells are implicated in psoriasis pathogenesis.

RESUMO

The mutation status of the BRAF and NRAS genes in tumor tissue is used to select patients with metastatic melanoma for targeted therapy. Cell-free circulating DNA (cfDNA) represents an accessible, non-invasive surrogate sample that could provide a snapshot of the BRAF and NRAS genotype in these patients. We investigated the feasibility of the Idylla™ assay for detection of BRAF and NRAS mutations in cfDNA of 19 patients with metastatic melanoma at baseline and during the course of treatment. The cfDNA genotype obtained with Idylla was compared to the results obtained with matched-tumor tissue and to clinical outcome. At baseline, 47% of patients harbored a BRAFV600 mutation in their cfDNA. Two months after targeted treatment the BRAFV600 mutant cfDNA was undetectable in all patients and 3 were disease-free. Moreover, 15% of patients harbored a NRAS mutation that was detected with plasma before treatment. The sensitivity and specificity were 80% and 89% for the BRAF status, and 79% and 100% for the NRAS status in pretreatment cfDNA compared to results obtained with a tissue test. Due to the small size of the population, no significant correlation was observed between the presence of BRAF or NRAS mutations in cfDNA and the metastatic tumor load or overall survival. In conclusion, this study demonstrated that evaluation with the Idylla system of the BRAF and NRAS mutation status in cfDNA may be a surrogate for determination of the BRAF and NRAS status in tumor tissue.
