Phase 1b Study of the Immunocytokine Simlukafusp alfa (FAP-IL2v), in Combination with Cetuximab in Patients with Head and Neck Squamous Cell Carcinoma.

PURPOSE: This phase 1b trial evaluated FAP-IL2v, a novel immune-cytokine engineered to minimize CD25-mediated toxicities, in combination with cetuximab, in patients with recurrent, unresectable, or metastatic head and neck squamous cell carcinoma (HNSCC). PATIENTS AND METHODS: Patients received FAP-IL2v either on a continuous weekly (QW) schedule, or QW for 4 weeks and then every 2 weeks (Q2W). Cetuximab was dosed at QW or Q2W schedules. The primary objectives were to evaluate the safety and tolerability, maximum tolerated dose (MTD), pharmacokinetics, and clinical activity for the combination of FAP-IL2v with cetuximab. Exploratory objectives included pharmacodynamic analyses. RESULTS: A total of 58 patients were enrolled, 19 patients into the dose-escalation, and 39 patients into the expansion part. The MTD of FAP-IL2v was defined as 10 mg (QW/Q2W) in combination with cetuximab (500 mg/m2, Q2W), which was further tested in the expansion part. The most common FAP-IL2v-related adverse events with a grade 3 or 4 severity were hypophosphatemia (19%), lymphopenia (16%), and infusion-related reaction (14%). The pharmacokinetics of FAP-IL2v in combination with cetuximab was similar to that after administration as monotherapy. Consistent with the proposed mode-of-action, FAP-IL2v preferentially expanded intratumoral NK and CD8 T cells. Four patients achieved a partial response, the objective response rate was 7% (95% CI: 3.2, 14.7). CONCLUSIONS: The safety profile of FAP-IL2v in combination with cetuximab was acceptable and pharmacodynamic markers support the proposed mode-of-action of this combination, but the overall low antitumor activity does not warrant further clinical exploration in HNSCC.

Phase 2 study of the antitumour activity and safety of simlukafusp alfa (FAP-IL2v) combined with atezolizumab in patients with recurrent and/or metastatic cervical squamous cell carcinoma.

BACKGROUND: Simlukafusp alfa (FAP-IL2v) is an immune cytokine engineered to selectively promote immune responses in the tumour microenvironment. We evaluated the antitumour activity and safety of FAP-IL2v plus atezolizumab in recurrent and/or metastatic cervical squamous cell carcinoma (SCC) in a phase 2 basket study (NCT03386721). METHODS: Patients with confirmed metastatic, persistent or recurrent cervical SCC who had progressed on ≥1 anti-cancer therapy and had measurable disease were enrolled. FAP-IL2v 10 mg was administered once every 3 weeks (Q3W) or once weekly (QW) for 4 weeks then once every 2 weeks (Q2W) with the corresponding Q3W or Q2W atezolizumab regimens. The primary endpoint was objective response rate by investigator assessment. FINDINGS: Forty-eight patients were enrolled (Q3W: n = 47; QW/Q2W: n = 1). Among 45 response evaluable patients, objective responses occurred in 12 patients (27%; CI 16.0-41.0), including 3 complete and 9 partial responses. Responses occurred in 6/19 PD-L1 positive patients (32%; 95% CI 15.4-54.0) and 5/24 PD-L1 negative patients (21%; 95% CI 9.2-35.6). Median duration of response was 13.3 months (95% CI 7.6-NE). Median progression-free survival was 3.7 months (95% CI 3.3-9.0). Adverse events (AEs) were consistent with the known safety profile of each drug. AEs leading to withdrawal of either agent occurred in 6 patients (13%). Pronounced expansion and activation of natural killer and CD8 T cells in peripheral blood and increased tumour infiltration and inflammation were observed. INTERPRETATION: FAP-IL2v plus atezolizumab is clinically active and has manageable safety in patients with recurrent and/or metastatic cervical SCC. FUNDING: F. Hoffmann-La Roche Ltd.

Addition of nitrous oxide and oxygen to carbon dioxide pneumoperitoneum during laparoscopic surgery for pain reduction: A double-blinded randomized controlled trial.

OBJECTIVE: To examine if peritoneal conditioning with an altered insufflation gas mixture is associated with reduced postoperative pain intensity compared to the standard insufflation gas (i.e., 100% CO2). DESIGN: A prospective, single-centre, randomized, double-blind, superiority trial was performed. SETTING: This study was conducted between 4 April 2019 and 10 February 2022 at the Jessa Hospital, Hasselt, Belgium. POPULATION: Patients scheduled for elective gynaecologic laparoscopic surgery. METHODS: Seventy-four patients scheduled for elective gynaecologic laparoscopic surgery were randomised to receive either the standard insufflation gas with 100 CO2 (n = 37; control group) or the altered gas mixture of 86% CO2, 10% N2O and 4% O2 (n = 37; experimental group). MAIN OUTCOME MEASURES: Postoperative pain was assessed at 4, 8 and 24 hours after surgery and on postoperative day (POD) 7 by an 11-point Numeric Rating Scale, with 0 indicating no pain and 10 indicating worst imaginable pain. RESULTS: No significant differences were found between the control and experimental groups regarding postoperative pain at 4, 8 and 24 h after surgery, as well as on POD7. In addition, the median (25% and 75%) total amount of IV piritramide consumption during the first 24 h after surgery was not significantly different between groups (control group: 18.0 [10.0, 27.0] mg vs. experimental group: 17.0 [10.0, 34.0] mg, p = 0.62). CONCLUSION: The alternative insufflation gas mixture comprising 86% CO2, 10% N2O and 4% O2 used for the pneumoperitoneum during gynaecologic laparoscopic surgery does not appear to reduce postoperative pain compared to the standard insufflation gas of 100% CO2.

The Impact of Music Perception on Quantitative Sensory Testing (QST).

Objective: The impact of listening to music on pain perception has been evaluated using questionnaires and numeric/visual analogue scales. In this study, the impact of music perception on sensory pain functions was measured by means of quantitative sensory testing. Methods: We enrolled 10 female and 10 male healthy subjects (10 of them were professional musicians). All subjects underwent, in total, four quantitative sensory testing measures (first: baseline; second: after pleasant music [Johannes Brahms, 3rd symphony, 3rd movement]; third: after unpleasant music [Krzysztof Penderecki, Threnos]; fourth: after a longer break). The pleasantness of music was evaluated using the Ertel differential scale. Results: After the participants listened to pleasant music, an increased sensitivity to cold stimuli (both threshold and pain), to mechanical stimuli (only for threshold), and to repeated stimuli (wind-up reaction) was noted. Listening to unpleasant music was not associated with changes in sensitivity. We did not observe any significant differences between male and female subjects or between musicians and non-musicians. There was no significant correlation between the rating of the music as pleasant/unpleasant and the different quantitative sensory testing measures. Conclusions: Our data show that listening to music inducing a pleasant feeling can increase the sensitivity to stimuli applied during a quantitative sensory testing session. This should be considered when performing or interpreting quantitative sensory testing examinations. Interestingly, this finding is in contrast to the observation that listening to music can decrease pain perception during painful procedures.

Phase II Study to Determine the Antitumor Activity and Safety of Simlukafusp Alfa (FAP-IL2v) Combined with Atezolizumab in Esophageal Cancer.

PURPOSE: In this study, we report the results from the esophageal squamous cell carcinoma (SCC) cohort of a phase II, noncomparative, basket study evaluating the antitumor activity and safety of fibroblast activation protein-IL2 variant (FAP-IL2v) plus atezolizumab in patients with advanced/metastatic solid tumors (NCT03386721). PATIENTS AND METHODS: Eligible patients had an Eastern Cooperative Oncology Group performance status of 0 to 1; measurable metastatic, persistent, or recurrent esophageal SCC; progression on ≥1 prior therapy; and were checkpoint inhibitor-naïve. Patients received FAP-IL2v 10 mg plus atezolizumab 1,200 mg intravenously every 3 weeks, or FAP-IL2v weekly for 4 weeks and then every 2 weeks plus atezolizumab 840 mg intravenously every 2 weeks. The primary endpoint was investigator-assessed objective response rate (ORR). RESULTS: In the response-evaluable population (N = 34), the best confirmed ORR was 20.6% [95% confidence interval (CI), 10.4-36.8], with a complete response seen in 1 patient and partial responses in 6 patients. The disease control rate was 44.1% (complete response = 2.9%; partial response = 17.6%; stable disease = 23.5%), and the median duration of response was 10.1 mon/ths (95% CI, 5.6-26.7). The median progression-free survival was 1.9 months (95% CI, 1.8-3.7). Analysis of response by PDL1 expression (Ventana SP263) resulted in an ORR of 26.7% for patients with PDL1-positive tumors (tumor area positivity cutoff ≥1%; n = 15) and 7.1% for patients with PDL1-negative tumors (tumor area positivity cutoff <1%; n = 14). Overall, the treatment combination was tolerable, and adverse events were consistent with the known safety profiles of each drug. CONCLUSIONS: FAP-IL2v plus atezolizumab demonstrated clinical activity and was tolerable in patients with previously treated esophageal SCC.

Safety, Pharmacokinetics, Pharmacodynamics, and Antitumor Activity from a Phase I Study of Simlukafusp Alfa (FAP-IL2v) in Advanced/Metastatic Solid Tumors.

PURPOSE: Simlukafusp alfa [fibroblast activation protein α-targeted IL2 variant (FAP-IL2v)], a tumor-targeted immunocytokine, comprising an IL2 variant moiety with abolished CD25 binding fused to human IgG1, is directed against fibroblast activation protein α. This phase I, open-label, multicenter, dose-escalation, and extension study (NCT02627274) evaluated the safety, pharmacokinetics, pharmacodynamics, and antitumor activity of FAP-IL2v in patients with advanced/metastatic solid tumors. PATIENTS AND METHODS: Participants received FAP-IL2v intravenously once weekly. Dose escalation started at 5 mg; flat dosing (≤25 mg) and intraparticipant uptitration regimens (15/20, 20/25, 20/20/35, and 20/35/35 mg) were evaluated. Primary objectives were dose-limiting toxicities, maximum tolerated dose, recommended expansion dose, and pharmacokinetics. RESULTS: Sixty-one participants were enrolled. Dose-limiting toxicities included fatigue (flat dose 20 mg: n = 1), asthenia (25 mg: n = 1), drug-induced liver injury (uptitration regimen 20/25 mg: n = 1), transaminase increase (20/25 mg: n = 1), and pneumonia (20/35/35 mg: n = 1). The uptitration regimen 15/20 mg was determined as the maximum tolerated dose and was selected as the recommended expansion dose. Increases in peripheral blood absolute immune cell counts were seen for all tested doses [NK cells, 13-fold; CD4+ T cells (including regulatory T cells), 2-fold; CD8+ T cells, 3.5-fold] but without any percentage change in regulatory T cells. Clinical activity was observed from 5 mg [objective response rate, 5.1% (n = 3); disease control rate, 27.1% (n = 16)]. Responses were durable [n = 3, 2.8 (censored), 6.3, and 43.4 months]. CONCLUSIONS: FAP-IL2v had a manageable safety profile and showed initial signs of antitumor activity in advanced/metastatic solid tumors.

Acute Treatment Patterns, Migraine Burden, and Healthcare Resource Use in People With Migraine: Results From the OVERCOME (EU) Observational Study.

INTRODUCTION: The ObserVational survey of the Epidemiology, tReatment and Care Of MigrainE (OVERCOME) European Union (EU) is part of an overarching population-based study program that also includes the United States and Japan. Here, we report data on the migraine/severe headache burden and the use of acute medication and healthcare resources in Spain and Germany. METHODS: OVERCOME (EU) was an online, non-interventional, cross-sectional survey conducted in adults in Spain and Germany between October 2020 and February 2021. A total migraine cohort was established based on health survey participants who reported headache/migraine in the last 12 months AND identified as having migraine based on modified International Classification of Headache Disorders, third edition criteria OR self-reported physician diagnosis. Data were analyzed for the total migraine cohort and the subcohort with moderate to severe headache attacks, with average pain severity ≥ 5 points, pain duration ≥ 4 h, and at least moderate disability due to migraine [Migraine Disability Assessment (MIDAS) score ≥ 11] over the past 3 months. RESULTS: Pain of moderate or severe intensity was the most frequent symptom in the total migraine cohort (n = 19,103/20,756; 92.0%). Proportions of participants reporting severe disability (MIDAS Grade IV), poorer quality of life (QoL; Migraine-Specific QoL Questionnaire), and higher interictal burden (Migraine Interictal Burden Scale-4), generally increased with number of headache days (HDs)/month. Most participants (92.5%) reported current acute migraine/severe headache medication use, although only 39.0% were using triptans. In the moderate to severe attacks subcohort (n = 5547), 48.4% were using triptans, with nonsteroidal anti-inflammatory drugs the most common acute medication. The moderate to severe attacks subcohort also reported poorer QoL and greater pain and disability with increasing HDs/month, although severe interictal burden was reported for ~ 60% of participants regardless of HDs/month. Treatment satisfaction (six-item migraine Treatment Optimization Questionnaire) in those using triptans was generally poor in both total and subcohorts. CONCLUSION: High migraine-related burden levels were reported, despite use of acute medication. Although triptans are recommended for moderate to severe migraine attacks in Spanish and German guidelines, less than half of participants were using triptans; treatment satisfaction in those using triptans was generally poor. New tailored treatment options may help address unmet needs in current acute treatment.

The description of epileptic seizures in the classical opera.

Epilepsy or epileptic seizures have only rarely been described in the classical opera. Four operas were detected, in which epileptic seizures are described also by musical means. Three of them ("Der Golem" by Eugen d'Albert; "Idiot" by Mieczyslaw Weinberg; "Otello" by Giuseppe Verdi) describe a generalized tonic-clonic epileptic seizure by a descending chromatic scale. One opera ("The turn of the screw" by Benjamin Britten) describes temporal lobe seizures by overtone music played by the instrument celesta.

A comprehensive approach for evaluating the virucidal performance of domestic laundry detergents under practical conditions.

AIMS: We aimed to develop a method to assess the virucidal performance of domestic laundry in a lab-scale washing machine (Rotawash) based on EN 17658. METHODS AND RESULTS: For method development, virus recovery was investigated after drying on cotton carriers for three test viruses murine norovirus (MNV), modified vaccinia virus Ankara (MVA), and bovine coronavirus (BCoV), followed by washing simulations in flasks and Rotawash. MNV and MVA demonstrated sufficient recovery from carriers after drying and washing (up to 40°C and 60 min). BCoV exhibited lower recovery, indicating less relevance as a test virus. Rotawash efficacy tests conducted with MNV, a resistant, non-enveloped virus, showed limited efficacy of a bleach-free detergent, aligning with results from a domestic washing machine. Rotawash washes achieved higher reductions in infectious virus titers than suspension tests, indicating the role of washing mechanics in virus removal. CONCLUSIONS: This study established a practical method to test the virucidal efficacy of laundry detergents in Rotawash, simulating domestic washing.

OnabotulinumtoxinA: Discussion of the evidence for effectiveness of OnabotulinumA and its place in chronic migraine treatment.

OnabotulinumtoxinA is a potent inhibitor of muscle contraction that acts by preventing the release of acetylcholine at the neuromuscular junction. In pain states such as migraine, its mechanism of action is not yet fully elucidated and probably relates to the phenomena of central and peripheral sensitization within the trigeminal system. Migraine is a prevalent and disabling disorder and, especially in its variant of chronic migraine (CM), is associated with relevant symptomatic and socioeconomic burden, the objective of preventive treatment being to reduce the frequency, duration, or severity of migraine attacks. OnabotulinumtoxinA, administered by intramuscular injection, is approved for the prevention of CM and is among the most utilized preventive treatments in CM and fundamental to clinical practice. The efficacy and safety of OnabotulinumtoxinA in the treatment of CM have been verified by the PREEMPT 1 and 2 studies and confirmed by the real-world studies that followed, including the COMPEL, REPOSE, and CM PASS. OnabotulinumtoxinA not only reduces headache days but also leads to improvement in functioning and quality of life, thereby reducing migraine impact. Data about its pathophysiology, efficacy, and its place in CM treatment in the era of CGRP monoclonal antibodies are reviewed and discussed here.

Obinutuzumab Pretreatment as a Novel Approach to Mitigate Formation of Anti-Drug Antibodies Against Cergutuzumab Amunaleukin in Patients with Solid Tumors.

PURPOSE: The immunocytokine cergutuzumab amunaleukin (CEA-IL2v) showed manageable safety and favorable pharmacodynamics in phase I/Ib trials in patients with advanced/metastatic carcinoembryonic antigen-positive (CEA+) solid tumors, but this was accompanied by a high incidence of anti-drug antibodies (ADA). We examined B-cell depletion with obinutuzumab as a potential mitigation strategy. EXPERIMENTAL DESIGN: Preclinical data comparing B-cell depletion with rituximab versus obinutuzumab are summarized. Substudies of phase I/Ib trials investigated the effect of obinutuzumab pretreatment on ADA development, safety, pharmacodynamics, and antitumor activity of CEA-IL2v ± atezolizumab in patients with advanced/metastatic or unresectable CEA+ solid tumors who had progressed on standard of care. RESULTS: Preclinical data showed superior B-cell depletion with obinutuzumab versus rituximab. In clinical studies, patients received CEA-IL2v monotherapy with (n = 16) or without (n = 6) obinutuzumab pretreatment (monotherapy study), or CEA-IL2v + atezolizumab + obinutuzumab pretreatment (n = 5; combination study). In the monotherapy study, after four cycles (every 2 weeks treatment), 0/15 evaluable patients administered obinutuzumab pretreatment had ADAs versus 4/6 patients without obinutuzumab. Obinutuzumab pretreatment with CEA-IL2v monotherapy showed no new safety signals and pharmacodynamic data suggested minimal impact on T cells and natural killer cells. Conversely, increased liver toxicity was observed in the combination study (CEA-IL2v + atezolizumab + obinutuzumab pretreatment). CONCLUSIONS: These preliminary findings suggest that obinutuzumab pretreatment before CEA-IL2v administration in patients with CEA+ solid tumors may be a feasible and potent ADA mitigation strategy, with an acceptable safety profile, supporting broader investigation of obinutuzumab pretreatment for ADA mitigation in other settings.

Migraine with aura.

This chapter describes the different types of aura including rare aura subtypes such as retinal aura. In addition, aura manifestations not classified in the International Classification of Headache Disorders and auras in headache disorders others than migraine are also described. The differential diagnosis of migraine aura comprises several neurological disorders which should be known to specialists. Migraine aura also has impact on the choice of migraine treatment; recommendations for the treatment of the migraine aura itself are also presented in this chapter.

Did Martin Luther suffer from vestibular migraine?

Martin Luther (1483-1546) reported attacks of headache and of vertigo in his letters and in his lectures. The symptomatology of his headache attacks fulfilled, at least in part, the diagnostic semiological criteria of migraine. However, because we cannot be sure about the time pattern and the exclusion of other disorders that might explain the headache, the diagnosis of migraine is not final. The vertigo attacks sometimes fulfilled the criteria of Ménière's disease. Vertigo also occurred together with headache attacks fulfilling the International Classification of Headache Disorders, 3rd edition criteria for vestibular migraine; however, we do not know exactly the pattern of attack frequency and duration. In summary, it is possible that Martin Luther suffered from attacks of vestibular migraine and had in addition a comorbidity of migraine and Ménière's disease.

The Cerebellum in Musicology: a Narrative Review.

The cerebellum is involved in cognitive procressing including music perception and music production. This narrative review aims to summarize the current knowledge on the activation of the cerebellum by different musical stimuli, on the involvement of the cerebellum in cognitive loops underlying the analysis of music, and on the role of the cerebellum in the motor network underlying music production. A possible role of the cerebellum in therapeutic settings is also briefly discussed. In a second part, the cerebellum as object of musicology (i.e., in classical music, in contemporary music, cerebellar disorders of musicians) is described.

Preventive treatment patterns and treatment satisfaction in migraine: results of the OVERCOME (EU) study.

BACKGROUND: Insights into the burden, needs and treatment of migraine from internet-based surveys in diverse real-world migraine populations are needed, especially at a time when novel preventive migraine medications are becoming part of the therapeutic armamentarium. The objectives of this analysis are to describe traditional preventive (orals and onabotulinum toxin A) treatment patterns in the OVERCOME (EU) study migraine cohort, as well as treatment patterns and patient satisfaction with current treatment in a subgroup of respondents eligible for migraine preventive medication. METHODS: The cross-sectional non-interventional OVERCOME (EU) study was conducted (October 2020-February 2021) via an online survey among adults (aged ≥ 18 years) resident in Germany or Spain. Participants, registered in existing online panels, who were willing to provide consent were considered. The migraine cohort included participants reporting headache/migraine in the past year, identified based on a validated migraine diagnostic questionnaire and/or self-reported physician diagnosis. A subgroup of survey respondents defined as eligible for migraine preventive medication at the point in time the cross-sectional survey was taken was also analysed. Variables assessed included sociodemographic and migraine-related clinical characteristics, preventive (traditional and calcitonin gene-related peptide monoclonal antibodies) treatment patterns and patient satisfaction with current treatment. Results are descriptive only. RESULTS: Of the 20,756 participants in the migraine cohort, 78.5% sought professional medical care, 50.8% received a migraine diagnosis and only 17.7% had ever used preventive medication. Half (53.3%) of participants currently using preventives took their most recent medication for six months or less. Most patients (73.9%) classified as eligible for preventive medication (based on headache frequency and/or at least moderate disability due to migraine) reported not using traditional preventives and many of those who did (66.8%) were not satisfied with their current standard of care. CONCLUSIONS: Our findings highlight the low proportion of people diagnosed with migraine despite a higher rate of consultation and suggest the need for better access to treatment for people with migraine and new preventive therapies with improved efficacy and safety profiles to improve adherence and patient satisfaction.

European Academy of Neurology guidelines on the treatment of cluster headache.

BACKGROUND AND PURPOSE: Cluster headache is a relatively rare, disabling primary headache disorder with a major impact on patients' quality of life. This work presents evidence-based recommendations for the treatment of cluster headache derived from a systematic review of the literature and consensus among a panel of experts. METHODS: The databases PubMed (Medline), Science Citation Index, and Cochrane Library were screened for studies on the efficacy of interventions (last access July 2022). The findings in these studies were evaluated according to the recommendations of the European Academy of Neurology, and the level of evidence was established using GRADE (Grading of Recommendations Assessment, Development, and Evaluation). RECOMMENDATIONS: For the acute treatment of cluster headache attacks, there is a strong recommendation for oxygen (100%) with a flow of at least 12 L/min over 15 min and 6 mg subcutaneous sumatriptan. Prophylaxis of cluster headache attacks with verapamil at a daily dose of at least 240 mg (maximum dose depends on efficacy and tolerability) is recommended. Corticosteroids are efficacious in cluster headache. To reach an effect, the use of at least 100 mg prednisone (or equivalent corticosteroid) given orally or at up to 500 mg iv per day over 5 days is recommended. Lithium, topiramate, and galcanezumab (only for episodic cluster headache) are recommended as alternative treatments. Noninvasive vagus nerve stimulation is efficacious in episodic but not chronic cluster headache. Greater occipital nerve block is recommended, but electrical stimulation of the greater occipital nerve is not recommended due to the side effect profile.
