Adverse Events Associated with Encorafenib Plus Cetuximab in Patients with BRAFV600E-mutant Metastatic Colorectal Cancer: An in-depth Analysis of the BEACON CRC Study.

BACKGROUND: The BRAF inhibitor encorafenib in combination with cetuximab was recently approved for patients with BRAFV600E-mutated (BRAFV600Emut) metastatic colorectal cancer (mCRC). Approval was based on positive results from the phase 3 BEACON CRC study in BRAFV600Emut mCRC patients who had progressed after 1-2 previous regimens. This analysis provides a detailed examination of the adverse events (AEs) of interest (AEIs) with encorafenib+cetuximab in the BEACON study to aid gastrointestinal oncologists, given the limited experience with this combination. MATERIALS AND METHODS: AEIs, including dermatological AEs, arthralgia/myalgia, nausea/vomiting, diarrhea, abdominal pain, fatigue/asthenia and nephrotoxicity, were examined in the doublet therapy group. Clinical characteristics associated with these AEs, AE grade, time to onset and time to resolution were also studied. RESULTS: Safety analysis included 216/220 patients randomized to doublet therapy. The most commonly occurring AEI was dermatological toxicity (75.5%), followed by arthralgia/myalgia (56.0%) and fatigue/asthenia (56.0%). Other than nephrotoxicity (7 patients; 5/7 with Grade 3 or 4), most AEs were Grade 1 or 2. Most AEs were more common in women than men (nausea/vomiting, diarrhea, abdominal pain, dermatological AEs, and arthralgia/myalgia). Nausea/vomiting, abdominal pain and fatigue/asthenia were more common in patients aged ≥70 years. Most AEs developed early, within the first 1-2 months of treatment, and resolved within 1-2 weeks. In addition, survival outcomes were better in patients experiencing arthralgia/myalgia or dermatological toxicities. CONCLUSION: This analysis indicated that, except for rare cases of nephrotoxicity, encorafenib+cetuximab is well tolerated in most patients, with most AEIs being mild-to-moderate in severity, occurring early and resolving rapidly. CLINICAL TRIAL REGISTRATION: the BEACON study (ClinicalTrials.gov, NCT02928224; EudraCT, 2015-005805-35).

A Phase I Study of Capivasertib in Combination With Abiraterone Acetate in Patients With Metastatic Castration-Resistant Prostate Cancer.

BACKGROUND: Although androgen receptor-targeted agents prolong the lives of patients with metastatic prostate cancer, patients develop therapy resistance and most ultimately succumb to the disease. The PI3K/AKT/PTEN pathway has been associated with the development of resistance, raising the possibility that pathway inhibitors may produce a clinical benefit. This open-label phase Ib study examined the safety, tolerability, pharmacokinetics (PK) and preliminary clinical activity of adding capivasertib - a potent, selective inhibitor of AKT1/2/3 - to approved abiraterone acetate therapy. METHODS: Twenty-seven patients with metastatic castration-resistant prostate cancer who had undergone at least 1 prior line of systemic therapy received abiraterone acetate 1000 mg (orally administered once daily), plus oral prednisone 5 mg (twice daily) with capivasertib 400 mg (orally, twice daily, with an intermittent schedule of 4 days on, 3 days off). RESULTS: No dose-limiting toxicity was observed. The most frequent adverse events (all grade) were diarrhea (30%), anemia (26%), asthenia (22%), and nausea (22%). The most frequent grade 3 or higher adverse events were acute kidney injury (19%), hyperglycemia (7%), rash (7%), abdominal pain (7%), and asthenia (7%). Capivasertib and abiraterone PK were consistent with previously reported results from monotherapy dosing. Nine participants (33%) showed a 20% or greater decrease in prostate-specific antigen during study treatment. CONCLUSION: The combination of capivasertib and abiraterone acetate had an acceptable tolerability profile consistent with the known profile of each agent. These data support further evaluation of capivasertib and abiraterone acetate in patients with advanced prostate cancer.

FOLFOXIRI and bevacizumab in patients with early-onset metastatic colorectal cancer. A pooled analysis of TRIBE and TRIBE2 studies.

BACKGROUND: We performed a pooled analysis of TRIBE and TRIBE2 studies to assess the efficacy and safety of the intensification of upfront chemotherapy backbone - from doublets to the triplet FOLFOXIRI - in combination with bevacizumab (bev) in patients with early-onset metastatic colorectal cancer (EO-mCRC; aged <50 years) and to explore whether EO-mCRCs have a peculiar tumour genomic profiling. MATERIALS AND METHODS: Subgroup analyses according to age (<50 versus ≥50 years) and treatment (FOLFOXIRI/bev versus doublets/bev) were carried out for rates of any grade and grade ≥3 (≥G3) overall and singular adverse events, progression-free survival (PFS), overall survival (OS) and objective response rate (ORR). Tumour genomic profiling was obtained using a DNA-based next-generation sequencing platform. RESULTS: Of 1187 patients included, 194 (16%) patients were aged <50 years. Females were more frequently diagnosed with EO-mCRC (P = 0.04). Patients aged <50 years showed a lower risk of ≥G3 neutropenia (P = 0.07), diarrhoea (P = 0.04), asthenia (P = 0.008) and a higher risk of any grade nausea (P < 0.01) and vomiting (P < 0.01). Patients receiving FOLFOXIRI/bev more frequently experienced ≥G3 chemotherapy-related adverse events respect to doublets/bev, regardless of age (Pinteraction = 0.60). FOLFOXIRI/bev was associated to a lower incidence of neutropenia (P = 0.04) and asthenia (P = 0.01) in patients <50 years old, than those aged ≥50 years. PFS, OS and ORR did not differ according to age (PFS P = 0.81, OS P = 0.44, ORR P = 0.50) and no interaction between age and the benefit from the intensification of upfront chemotherapy was observed (PFS Pinteraction = 0.72, OS Pinteraction = 0.54, ORR Pinteraction = 0.65). Genomic profiling was assessed in 296 patients, showing an enrichment of FBXW7 and POLE mutations in EO-mCRC. CONCLUSIONS: Upfront FOLFOXIRI/bev shows a favourable efficacy/safety balance in EO-mCRC. TRIAL REGISTRATION: Clinicaltrials.gov Identifiers NCT00719797, NCT0233-9116.

Real-world burden of adverse events for apalutamide- or enzalutamide-treated non-metastatic castration-resistant prostate cancer patients in the United States.

BACKGROUND: Second-generation androgen receptor inhibitors (ARIs) have been associated with adverse events (AEs) such as fatigue, falls, fractures, and rash in non-metastatic castration-resistant prostate cancer (nmCRPC) patients as identified in clinical trials. The objectives of this study were to describe the incidence and management of AEs in patients receiving apalutamide and enzalutamide. METHODS: This retrospective chart review study was conducted in nmCRPC-treating sites in the United States. Patients starting apalutamide or enzalutamide between February 1, 2018 and December 31, 2018 were included and any AEs they experienced were recorded. AEs, including those considered to be of special interest as defined in the pivotal clinical trials of the second-generation ARIs, were analyzed and grouped retrospectively in this study. Detailed chart data (patient demographics, clinical characteristics, treatment history, type of AE, outcomes, and resource utilization) were then collected for a randomly selected subset among patients with ≥1 AE to characterize AEs and their management. Descriptive results were summarized. RESULTS: Forty-three sites participated in the study. A total of 699 patients were included, of whom 525 (75.1%) experienced ≥1 AE. The most common AEs were fatigue/asthenia (34.3%), hot flush (13.9%), and arthralgia (13.6%). In the subset of 250 patients randomly selected from those who experienced ≥1 AE, patients were primarily White (72.0%), the mean age was 71 years, 86.0% had an Eastern Cooperative Oncology Group score of 0-1 at nmCRPC diagnosis, and the average prostate specific antigen (PSA) value at diagnosis was 23.2 ng/mL. PSA-doubling time < 10 months was chosen as reason to initiate treatment in 40% of patients. The median duration of follow-up was 1.1 years, with 14.4% of patients progressing to metastasis by end of study period. Grade 3-4 and Grade 5 AEs occurred in 14.4 and 0.4% of patients, respectively. Actions taken to manage AEs included AE-directed treatment (38.0%), ARI discontinuation (10.4%), dose reduction (7.6%), and AE-related hospitalization (4.8%). CONCLUSIONS: This study highlights the burden of AEs among nmCRPC patients treated with apalutamide or enzalutamide, providing a relevant real-world benchmark as clinical trial evidence and the treatment landcape for nmCRPC continues to evolve.

Real-world safety and effectiveness of regorafenib in metastatic colorectal cancer: the French CORRELATE cohort.

Aim: We report real-world evidence with regorafenib in previously treated metastatic colorectal cancer from the French cohort of the international, prospective, observational CORRELATE study. Patients & methods: Patients receiving regorafenib according to French health authority approval were included. The primary end point was treatment-emergent adverse events. Overall survival and progression-free survival were secondary end points. Results: Two hundred and forty-two patients (61% male, median age: 66 years) were enrolled. The most common grade ≥3 drug-related treatment-emergent adverse events were hand-foot skin reaction (10.3%), asthenia/fatigue (9.9/1.2%) and hypertension (6.2%). Median overall survival and progression-free survival were 6.8 (95% CI: 6.3-7.6) and 2.8 months (95% CI: 2.6-3.0), respectively. Conclusion: The real-world safety and effectiveness data of regorafenib in metastatic colorectal cancer in France align with findings from Phase III clinical trials and the global CORRELATE population.

Experience with Omalizumab for the treatment of chronic spontaneous urticaria in a tertiary center: real life experience.

PURPOSE: Chronic spontaneous urticaria (CSU) is defined as urticaria and/or angioedema that appears spontaneously due to known or unknown causes and lasts for at least 6 weeks. Omalizumab, an anti-IgE antibody that binds circulating free IgE, has recently emerged as a promising treatment for CSU, a condition which impairs patients' quality of life. We aimed to contribute real life data by reporting our experience with omalizumab in the treatment of intractable CSU. METHODS: Of 140 patients treated with omalizumab in our clinic between September 2013 and January 2018, 86 CSU patients with available current data were retrospectively evaluated in terms of sex, age, urticaria duration, urticaria activity score over 7 days (UAS7) before and after omalizumab, relapses and time to relapse, length of remission after omalizumab cessation, adverse events, and comorbidities. RESULTS: The mean age of the patients was 45.5 ± 14.3 years and 73.3% were women. Mean duration of urticaria before initiation of omalizumab therapy was 54.5 ± 67 months. All patients had used antihistamines before starting omalizumab treatment. The mean number of omalizumab doses was 11.9 ± 9.3. The mean duration of omalizumab treatment was 13.3 ± 10.4 months. Mean UAS7 score was 38.9 ± 4.1 before the start of omalizumab treatment, and 7.9 ± 10.5 after treatment. Treatment was discontinued in 10 patients (11.6%) due to nonresponse or loss of effect. Four patients (4.65%) experienced adverse events. Treatment was discontinued in 1 patient (1.16%) due to side effects. Of the 55 patients whose treatment was discontinued after their symptoms resolved, 31 (56.3%) relapsed after omalizumab cessation. Twenty-four patients (43.6%) did not relapse after omalizumab cessation. CONCLUSIONS: Our results show that omalizumab was an effective treatment for intractable CSU and did not cause any serious adverse effects other than asthenia, vertigo, and injection site reaction in four patients. These findings are relevant because they reflect real-life data.

[A rare cause of impaired general condition: Muscular and cardiac toxicity of antimalarials]. / Une cause rare d'altération de l'état général : cardiopathie et myopathie aux antipaludéens de synthèse.

INTRODUCTION: This case report signifies the need to systemically assess antimalarial toxicity in those undergoing long-term treatment. CASE REPORT: A 59-year-old man with a history of ischemic-labeled heart disease revealed by conduction disorders and cutaneous lupus treated initially with hydroxychloroquine followed by chloroquine consulted for asthenia and weight loss. Clinically, he had a muscular atrophy, a motor deficit, and an abolition of the osteo-tendinous reflexes in the lower limbs. Adverse drug effects of the antimalarial therapy were suspected-specifically, muscular and cardiac toxicity. The diagnosis was confirmed with a muscle biopsy, which showed typical and florid vacuolar myopathy. Cessation of the drug resulted in a slow regression of symptoms. CONCLUSION: Cardiac and muscular toxicity related to antimalarials are rare and sometimes fatal; thus, they must be systematically assessed in a patient with several years of exposure. A muscle biopsy could be sufficient to allow for the diagnosis.

Pharmacokinetic/Pharmacodynamic Relationship of Enzalutamide and Its Active Metabolite N-Desmethyl Enzalutamide in Metastatic Castration-Resistant Prostate Cancer Patients.

INTRODUCTION: Enzalutamide (ENZA) is an oral androgen receptor inhibitor approved by the Food and Drug Administration and the European Medicines Agency for the treatment of metastatic and nonmetastatic castration-resistant prostate cancer (CRPC). ENZA is extensively metabolized by cytochrome P450 3A4 into N-desmethyl ENZA (NDE), an active metabolite. We aimed to explore the pharmacokinetic/pharmacodynamic relationship for ENZA and NDE in metastatic CRPC patients from a real-world setting. PATIENTS AND METHODS: Trough plasma concentration (Ctrough) of ENZA and NDE were assayed using liquid chromatography coupled with UV detection. The relationship between ENZA, NDE, and composite (ENZA with NDE) plasma concentration and requirement of ENZA dose reduction was investigated using the Mann-Whitney test. A survival univariate analysis was conducted to explore association between progression-free survival (PFS), overall survival (OS), and plasma Ctrough (ENZA, NDE, and composite). RESULTS: Twenty-two metastatic CRPC patients treated with ENZA (median age, 75.5 years; 13 patients (59%) with Eastern Cooperative Oncology Group status 0-1) were prospectively included. Mean plasma Ctrough of ENZA and NDE were 12.4 ± 3.0 µg/mL and 8.8 ± 2.1 µg/mL, respectively. Neither PFS nor OS were statistically associated with ENZA, NDE, or composite plasma Ctrough. In 4 patients (18%) who required ENZA dose reduction because of severe clinical toxicity, an increased ENZA plasma Ctrough was observed compared with 18 remaining patients (16.1 ± 2.4 µg/mL vs. 11.6 ± 2.6 µg/mL, respectively; P = .027). CONCLUSION: The low interindividual variability in ENZA and NDE Ctrough and the lack of relationship with survival do not support the need for plasma drug monitoring. Severe asthenia might be related to higher exposure and could be improved by decreasing ENZA dosing.

Olmesartan Associated Enteropathy: Usefulness of Video Capsule Endoscopy in a Case With Doubtful Upper Endoscopic/Histological Picture.

BACKGROUND: Olmesartan, an antihypertensive drug, may be associated with a severe "sprue-like enteropathy". OBJECTIVES: To report a case of Olmesartan enteropathy demonstrated by video capsule endoscopy distally from the second duodenum along with the whole small bowel before and after drug withdrawal. CASE PRESENTATION: A 81-years-old man was referred for asthenia, chronic watery diarrhea and anasarca (ascites, pleural effusion and edemas of superior and inferior limb). The only comorbidity was hypertension treated with Olmesartan. All causes of infective and inflammatory chronic diarrhea were investigated and excluded. Upper endoscopy was normal; histological examination of the second portion of the duodenum showed moderate and patchy infiltration of lymphocytes at mucosal and intra-epithelial level with intermittent partial villous atrophy. The possibility of adverse drug reaction, estimated by Naranjo scale, showed a score of 7, indicating a strong probability. Olmesartan was then withdrawn. However, because of severe clinical general condition, we preferred to corroborate our diagnostic work-up by a non-invasive investigation, i.e. video capsule endoscopy, which showed jejunal and ileal mucosal alterations (mosaic pattern, diffuse hyperemia, severe edema, consequent apparent reduced lumen, diffuse thickening of intestinal folds, multiple erosions, patchy lymphangectasia). After 14 days, the resolution of anasarcatic state and hydroelectrolytic imbalances was observed. Nine months later, small-bowel video-capsule demonstrated mild mucosal hyperaemia and mosaic pattern. CONCLUSION: Our case could give new insights in the field of Olmesartan associated enteropathy by highlighting the possibility of distally main lesion location and, therefore, the usefulness of video capsule endoscopy in the presence of doubtful diagnostic features.

A phase 2 study of panitumumab with irinotecan as salvage therapy in chemorefractory KRAS exon 2 wild-type metastatic colorectal cancer patients.

BACKGROUND: Targeted agents are standard treatment for RAS wild-type metastatic colorectal cancer in the first- and second-line settings. This phase 2 study determined the benefit of targeting the epidermal growth factor receptor (EGFR) with panitumumab plus irinotecan in irinotecan-refractory patients. METHODS: KRAS exon-2 wild-type patients failing prior irinotecan received panitumumab (6 mg/kg) and irinotecan (180 mg/m²) every 2 weeks. The primary endpoint was the overall response rate (ORR). Secondary endpoints included safety, progression-free survival (PFS) and overall survival (OS). KRAS exon-2 status was evaluated centrally, along with NRAS, BRAF mutations, epiregulin, amphiregulin, PTEN and EGFR copy number status, and correlated with efficacy. RESULTS: Sixty-one patients were treated. Among the 46 wild-type RAS patients, the ORR was 15.2% (seven partial responses), with median PFS of 3.8 months (95% CI 2.7-4.3) and median OS of 12.5 months (95% CI 6.7-15.9). Wild-type BRAF patients showed a 13.0% response rate. No significant correlations between response and baseline biomarker expression were identified. Common grade 3-4 adverse events were diarrhoea and rash (18.0% each), hypomagnesaemia and asthenia (8.2% each). CONCLUSIONS: The addition of panitumumab to irinotecan as salvage therapy is feasible but has limited activity in irinotecan-refractory metastatic colorectal cancer. No biomarkers predictive of response were identified.

Nilotinib efficacy, safety, adherence and impact on quality of life in newly diagnosed patients with chronic myeloid leukaemia in chronic phase: a prospective observational study in daily clinical practice.

This observational, prospective study assessed, in a daily clinical practice, the molecular response, safety, quality of life (QoL) and treatment adherence in 183 patients with chronic myeloid leukaemia in chronic phase (CML-CP), receiving nilotinib as first-line treatment. Premature study termination before 24 months of follow-up occurred in 61 patients (33·3%), and was essentially due to nilotinib treatment discontinuation (n = 53; 29%), motivated by treatment intolerance (n = 29; 15·8%) and inefficacy (n = 19; 10·4%). After 24 months of treatment, 112/122 patients (91·8%) had a molecular assessment, 95·5% of whom achieved a major molecular response (MMR), 32·1% achieved uMR4 , defined as an undetectable molecular disease with 4-log molecular response sensitivity (≥10 000 ABL1 transcripts). The Morisky Green Levine Medication Adherence Scale was completed by 94/122 patients (77·0%), and 89·4% of these patients obtained a satisfactory level of treatment adherence, defined as a score ≥3. Patients' QoL was good at baseline and stable during the follow-up period. The two most common nilotinib-related adverse events (AEs) were pruritus (14·8%) and asthenia (13·7%). Seven patients (3·8%) experienced at least one cardiovascular ischaemic AE. This French nationwide cohort study provides relevant information in daily clinical practice indicating that nilotinib is a valuable first-line treatment option for CML-CP patients.

Long-Term Outcome of Ustekinumab Therapy for Behçet's Disease.

OBJECTIVE: Oral ulcers, the hallmark lesion of Behçet's disease (BD), can be disabling and resistant to conventional treatment, and there is a need for safe and effective treatment. We undertook this study to investigate the long-term safety and efficacy of ustekinumab therapy for BD-related oral ulcers that are resistant to colchicine. METHODS: This multicenter, prospective, open-label study included 30 patients who fulfilled the criteria of the International Study Group for BD and who were diagnosed as having active oral ulcers resistant to colchicine. Patients were treated subcutaneously with ustekinumab 90 mg at inclusion, at week 4, and then once every 12 weeks. Each patient was assessed longitudinally for the presence and number of oral ulcers, and median numbers of oral ulcers (with interquartile range [IQR]) were calculated. The primary efficacy end point was the proportion of patients at week 12 who experienced complete response, defined as having no oral ulcers. RESULTS: The median number of oral ulcers per patient during ustekinumab therapy was significantly lower at week 12 compared to baseline (0 [IQR 0-1] versus 2 [IQR 2-3]; P < 0.0001). Complete response was achieved in 60.0% and 88.9% of patients at weeks 12 and 24, respectively. The median Behçet's Syndrome Activity Score (in which higher scores indicate more active disease) was significantly lower at weeks 12 and 24 (17.5 [IQR 10-42.5] and 10 [IQR 8-11], respectively) versus baseline (70 [IQR 50-70]; P < 0.0001). After a median follow-up of 12 months (IQR 6-16 months), 26 patients (86.7%) were still receiving ustekinumab treatment. Reasons for ustekinumab discontinuation included BD flare (n = 3) and side effects (n = 1). Seven patients (23.3%) experienced adverse events, including headaches (n = 4) and asthenia (n = 2), with no serious side effects. CONCLUSION: Ustekinumab seems to be effective in treating BD-related oral ulcers that are resistant to treatment with colchicine.

Primary Results from SAUL, a Multinational Single-arm Safety Study of Atezolizumab Therapy for Locally Advanced or Metastatic Urothelial or Nonurothelial Carcinoma of the Urinary Tract.

BACKGROUND: Atezolizumab, a humanised monoclonal antibody targeting PD-L1, is approved for locally advanced/metastatic urothelial carcinoma. SAUL evaluated atezolizumab in a broader, pretreated population, including patients ineligible for the pivotal IMvigor211 phase 3 trial of atezolizumab. OBJECTIVE: To determine the safety and efficacy of atezolizumab in an international real-world setting. DESIGN, SETTING, AND PARTICIPANTS: Between November 2016 and March 2018 (median follow-up 12.7mo), 1004 patients with locally advanced or metastatic urothelial or nonurothelial urinary tract carcinoma who experienced progression during or after one to three prior therapies for inoperable, locally advanced, or metastatic disease were enrolled. Patients with renal impairment, treated central nervous system metastases, or stable controlled autoimmune disease were eligible; 10% had Eastern Cooperative Oncology Group performance status (ECOG PS) 2 and 98% were platinum pretreated (Clinicaltrials.gov: NCT02928406). INTERVENTION: Atezolizumab 1200mg every 3wk until progression or unacceptable toxicity. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was safety. Secondary efficacy endpoints included overall survival (OS), progression-free survival (PFS), and overall response rate (ORR). RESULTS AND LIMITATIONS: The median treatment duration was 2.8mo (range 0-19); 22% remained on treatment and 8% discontinued because of toxicity. Grade ≥3 adverse events occurred in 45% of patients. The most common grade ≥3 treatment-related adverse events were fatigue, asthenia, colitis, and hypertension (each in 1%). Median OS was 8.7mo (95% confidence interval [CI] 7.8-9.9). The 6-mo OS rate was 60% (95% CI 57-63%), median PFS was 2.2mo (95% CI 2.1-2.4), and the ORR was 13% (95% CI 11-16%; 3% complete responses). Among IMvigor211-like patients (excluding ECOG PS 2 and other IMvigor211 exclusion criteria), median OS was 10.0mo (95% CI 8.8-11.9) and 6-mo OS was 65% (95% CI 61-69%). CONCLUSIONS: SAUL confirms the tolerability of atezolizumab in a real-world pretreated population with urinary tract carcinoma. Efficacy overall and in the IMvigor211-like subgroup is consistent with previous pivotal anti-PD-L1/PD-1 urothelial carcinoma trials. These results support the use of atezolizumab in urinary tract carcinoma, including patients with limited treatment options. PATIENT SUMMARY: In this international study we investigated the efficacy and safety of atezolizumab treatment for advanced urinary tract cancer in a large population of pretreated patients, including those who would not normally be candidates for clinical trials. Patients tolerated the treatment well, even if they had autoimmune disease, were being treated with corticosteroids, or had disease that had spread to their brain. Life expectancy in this study for patients typical of everyday clinical practice was similar to that seen in trials that enrolled only selected fitter patients.

The impact of chronic myeloid leukemia on employment: the French prospective study.

Patients with chronic myeloid leukemia treated with breakpoint cluster region-Abelson tyrosine kinase inhibitors are likely to survive in excess of 20 years after diagnosis. New challenges appear as we consider life after the disease, including professional challenges and the social reintegration of patients. The purpose of this study was to determine the impact of chronic myeloid leukemia on employment within 2 years after diagnosis. This prospective, observational study included patients diagnosed with chronic myeloid leukemia and treated with a tyrosine kinase inhibitor. Two populations were defined as patients who reported modifications in their professional activity during the study (Acti-Pro+) and patients who did not report a modification (Acti-Pro-). Cancer survivors received a self-assessment questionnaire. The primary endpoint was to determine the professional status of patients. One hundred patients completed the questionnaire. Sixty-six patients out of 100 reported professional activity within 2 years after their diagnosis. During the 2 years after the diagnosis, 65.2% (95% confidence interval (CI), 53.7-76.7) of patients faced modifications in their professional activity due to chronic myeloid leukemia or adverse effects of drug treatments (group Acti-Pro+); in contrast, 34.8% of patients did not report any impact on their occupational activity (group Acti-Pro-). Among modifications to work organization, a change in the number of working hours was the most represented. Other modifications comprised changes in status or work pace. A majority of chronic myeloid leukemia patients face professional consequences of their disease and treatments. Our findings suggest that adverse drug reactions are a major factor affecting the occurrence of work modifications in this context.

Real-Life Experience with Pirfenidone in Idiopathic Pulmonary Fibrosis in Argentina. A Retrospective Multicenter Study. / Experiencia de la vida real con pirfenidona en la fibrosis pulmonar idiopática en Argentina. Estudio retrospectivo multicéntrico.

INTRODUCTION: Pirfenidone was the first antifibrotic drug approved in Argentina for idiopathic pulmonary fibrosis (IPF). Outcomes in real life may differ from the results of clinical trials. The primary endpoint was to study the tolerance of pirfenidone in real life. Secondary endpoints were to analyze effectiveness and reasons for discontinuation. MATERIALS AND METHODS: Retrospective observational study conducted in 4 specialized centers in Argentina. We analyzed the medical records of patients with IPF who received pirfenidone between June 2013 and September 2016. Adverse events (AE) and the variables that could influence these results were analyzed. Forced vital capacity (FVC%) parameters were also compared between the pre-pirfenidone and post-pirfenidone periods. RESULTS: Fifty patients were included, 38 (76%) men, with mean age (SD) 67.8 (8.36) years. Mean (SD) exposure to pirfenidone was 645.68 (428.19) days, with a mean daily dose (SD) of 2,064.56mg (301.49). Nineteen AEs in 15 patients (30%) were reported: nausea (14%), asthenia (10%) and skin rash (8%). A total of 18 patients (36%) interrupted treatment, only 1 definitively. The most frequent reason for discontinuation was failure of suppliers to provide the drug (9 subjects; 18%). We compared the evolution of FVC% between the pre-pirfenidone and post-pirfenidone periods, and found a mean (SD) FVC% decline of 4.03% (7.63) pre-pirfenidone and 2.64% (7.1) post-pirfenidone (P=.534). CONCLUSIONS: In our study, pirfenidone was well tolerated and associated with a reduction in FVC decline, although without reaching statistical significance.

Clinical side effects after oral administration of palm oil and Alchornea cordifolia decoction in a child.

Alchornea cordifolia is known to be a plant with a variety of medicinal properties and is quoted by many traditional healers to treat a variety of medicinal problems in the Democratic Republic of Congo. However, very little is known about its potential toxicity. We report the case of a 9-year-old boy referred for assessment of suspected bronchial troubles without a history of atopic disease or drug allergy who developed dyspnea, dysphagia, asthenia and lingual ulcers within 30 minutes after nasal and oral administration of decoction of palm oil associated with A. cordifolia leaves in water. In the present report, adverse effects of A. cordifolia therapy may be related to the mixtures of active compounds that they contain and can cause the symptoms observed in our patient. These findings call for caution in the use of A. cordifolia especially in children.

Vismodegib: A Review in Advanced Basal Cell Carcinoma.

Vismodegib (Erivedge®) is the first-in-class, oral small molecule inhibitor of the Hedgehog (Hh) pathway, abnormal activation of which is associated with basal cell carcinoma (BCC). In the USA, vismodegib is indicated for the treatment of adults with metastatic BCC (mBCC) or with locally-advanced BCC (LaBCC) that has recurred following surgery or who are not candidates for surgery, and who are not candidates for radiation. Similarly, in the EU, vismodegib is indicated for the treatment of adult patients with symptomatic mBCC, or with laBCC inappropriate for surgery or radiotherapy. The full European approval of vismodegib was based on the results of two phase II, open-label, noncomparative, international trials (ERIVANCE BCC and STEVIE), both of which showed high rates of tumour control in the indicated patient populations, including individuals with or without Gorlin syndrome. These studies also showed that vismodegib has an acceptable and manageable tolerability profile characterized by a number of class-related treatment-emergent adverse events, including muscle spasms, taste disturbances, alopecia, weight loss and asthenia (fatigue). Primary and secondary resistance to vismodegib has been documented, albeit at a low rate compared with some other targeted therapies. Vismodegib is therefore an effective and generally well tolerated systemic therapy for patients with mBCC and laBCC that can no longer be suitably controlled with surgery and/or radiotherapy. Historically, it is the first member of a class of drugs (Hh pathway inhibitors) that are now considered to be first-line treatment options for such individuals.

Oral Metronomic Vinorelbine in Advanced Non-small Cell Lung Cancer Patients Unfit for Chemotherapy.

AIM: To explore the feasibility and activity of oral metronomic vinorelbine patients with advanced NSCLC not eligible to standard chemotherapy because of old age (≥70 years), and/or poor Eastern Cooperative Oncology Group performance status (≥2), and/or extensive brain or bone disease, and/or active comorbidities (≥2) requiring for pharmacological treatment. PATIENTS AND METHODS: In a prospective phase II not randomized study, patients with stage IV NSCLC unfit to chemotherapy were treated with oral metronomic vinorelbine at 30 mg fixed dose three times a week until disease progression. RESULTS: Fifty patients were treated, 19 (38%) in the first-line setting. Five patients (11%) experienced a grade 3 toxicity; no grade 4 toxicity occurred. Overall disease control rate was 32%, 44% and 26% in first and subsequent lines, respectively (p=0.39). Median OS and PFS were 7.3 months (95% confidence interval [CI]=4.7-10.0) and 2.7 months (95%CI=2.0-3.4), respectively. CONCLUSION: These data support the activity and safety of metronomic vinorelbine in a relevant proportion of patients usually excluded from any specific treatment.

Aflibercept Plus FOLFIRI in the Real-life Setting: Safety and Quality of Life Data From the Italian Patient Cohort of the Aflibercept Safety and Quality-of-Life Program Study.

BACKGROUND: Aflibercept combined with FOLFIRI (folinic acid, 5-fluorouracil, irinotecan) as second-line treatment of metastatic colorectal cancer (mCRC) significantly improved survival compared with FOLFIRI alone in the pivotal VELOUR (aflibercept vs. placebo in combination with irinotecan and 5-fluorouracil in the treatment of patients with metastatic colorectal cancer after failure of an oxaliplatin-based regimen) trial. No quality-of-life assessment was performed in VELOUR; therefore, the ASQoP (Aflibercept Safety and Quality-of-Life Program) trial was designed to capture the safety and health-related quality of life (HRQL). PATIENTS AND METHODS: ASQoP was an international, open-label, single-arm trial evaluating the safety and HRQL of aflibercept combined with FOLFIRI administered in a real-life setting to 781 patients with mCRC, pretreated with an oxaliplatin-based regimen with or without bevacizumab. The Italian subset of ASQoP enrolled 200 patients from 28 institutions. The primary endpoint was safety; HRQL was a secondary endpoint, assessed by validated questionnaires (European quality of life 5-dimension instrument 3-level; European Organization for Research and Treatment for Cancer Quality of Life Questionnaire Core 30, version 3; and EORTC-CR29) at baseline, during treatment, and at the end of treatment. RESULTS: The median age of the Italian ASQoP population was 63 years; the median number of aflibercept and FOLFIRI cycles was 7. Treatment-emergent adverse events were reported in 97.5% of patients. Hypertension (28.5%), neutropenia (27.5%; from laboratory data), asthenic conditions (20.0%), diarrhea (17.0%), and stomatitis (13.0%) were the most frequent (incidence, ≥ 5%) grade 3/4 toxicities. One toxic death occurred during the study period due to sepsis, without neutropenic complications. No significant worsening of HRQL was shown during treatment. CONCLUSION: Aflibercept combined with FOLFIRI was well tolerated when administered as second-line treatment for patients with mCRC in a real-life setting. It did not affect HRQL and showed similar rates of treatment-emergent adverse events as those observed in the VELOUR trial. No new safety signals were identified.

Relevance of CYP3A4*20, UGT1A1*37 and UGT1A1*28 variants in irinotecan-induced severe toxicity.

Severe irinotecan-induced toxicity is associated with UGT1A1 polymorphisms. However, some patients develop side-effects despite harbouring a normal UGT1A1 genotype. As CYP3A4 is also an irinotecan-metabolizing enzyme, our study aimed to elucidate the influence of the CYP3A4*20 loss-of-function allele in the toxicity profile of these patients. Three-hundred and eight metastatic colorectal cancer patients treated with an irinotecan-containing chemotherapy were studied. The presence of CYP3A4*20, UGT1A1*37 and UGT1A1*28 alleles was tested. Associations between these genetic variants and toxicity were evaluated. UGT1A1*28 was significantly associated with severe diarrhoea, neutropenia and asthenia (P = 0.002, P = 0.037 and P = 0.041, respectively). One patient with the UGT1A1*28/*37 genotype presented with grade IV neutropenia and lethal septic shock. One heterozygous UGT1A1 (*1/*28) patient also carried the CYP3A4*20 allele but did not develop toxicity. We confirm that UGT1A1*37 and UGT1A1*28 are associated with severe toxicity and suggest that the CYP3A4*20 allele does not play a role in irinotecan-induced toxicity.
