Abstract
Risdiplam is a once-daily oral, survival of motor neuron 2 (SMN2) splicing modifier approved for the treatment of spinal muscular atrophy (SMA). JEWELFISH (NCT03032172) investigated the safety, tolerability, pharmacokinetics (PK), and PK/pharmacodynamic (PD) relationship of risdiplam in non-treatment-naïve patients with SMA. JEWELFISH enrolled adult and pediatric patients (N = 174) with confirmed diagnosis of 5q-autosomal recessive SMA who had previously received treatment with nusinersen (n = 76), onasemnogene abeparvovec (n = 14), olesoxime (n = 71), or were enrolled in the MOONFISH study (NCT02240355) of the splicing modifier RG7800 (n = 13). JEWELFISH was an open-label study with all participants scheduled to receive risdiplam. The most common adverse event (AE) was pyrexia (42 patients, 24%) and the most common serious AE (SAE) was pneumonia (5 patients, 3%). The rate of AEs and SAEs decreased by > 50% from the first to the second year of treatment, and there were no treatment-related AEs that led to withdrawal from treatment. An increase in SMN protein in blood was observed following risdiplam treatment and sustained over 24 months of treatment irrespective of previous treatment. Exploratory efficacy assessments of motor function showed an overall stabilization in mean total scores as assessed by the 32-item Motor Function Measure, Hammersmith Functional Motor Scale-Expanded, and Revised Upper Limb Module. The safety profile of risdiplam in JEWELFISH was consistent with previous clinical trials of risdiplam in treatment-naïve patients. Exploratory efficacy outcomes are reported but it should be noted that the main aim of JEWELFISH was to assess safety and PK/PD, and the study was not designed for efficacy analysis. TRIAL REGISTRATION: The study was registered (NCT03032172) on ClinicalTrials.gov on January 24, 2017; First patient enrolled: March 3, 2017.

Abstract
INTRODUCTION Risdiplam is a survival of motor neuron 2 (SMN2) splicing modifier for the treatment of patients with spinal muscular atrophy (SMA). The JEWELFISH study (NCT03032172) was designed to assess the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of risdiplam in previously treated pediatric and adult patients with types 1-3 SMA. Here, an analysis was performed after all patients had received at least 1 year of treatment with risdiplam. METHODS Patients with a confirmed diagnosis of 5q-autosomal recessive SMA between the ages of 6 months and 60 years were eligible for enrollment. Patients were previously enrolled in the MOONFISH study (NCT02240355) with splicing modifier RG7800 or treated with olesoxime, nusinersen, or onasemnogene abeparvovec. The primary objectives of the JEWELFISH study were to evaluate the safety and tolerability of risdiplam and investigate the PK after 2 years of treatment. RESULTS A total of 174 patients enrolled: MOONFISH study (n = 13), olesoxime (n = 71 patients), nusinersen (n = 76), onasemnogene abeparvovec (n = 14). Most patients (78%) had three SMN2 copies. The median age and weight of patients at enrollment was 14.0 years (1-60 years) and 39.1 kg (9.2-108.9 kg), respectively. About 63% of patients aged 2-60 years had a baseline total score of less than 10 on the Hammersmith Functional Motor Scale-Expanded and 83% had scoliosis. The most common adverse event (AE) was upper respiratory tract infection and pyrexia (30 patients each; 17%). Pneumonia (four patients; 2%) was the most frequently reported serious AE (SAE). The rates of AEs and SAEs per 100 patient-years were lower in the second 6-month period compared with the first. An increase in SMN protein was observed in blood after risdiplam treatment and was comparable across all ages and body weight quartiles. CONCLUSIONS The safety and PD of risdiplam in patients who were previously treated were consistent with those of treatment-naïve patients.

Abstract
Risdiplam (EVRYSDI®) is a centrally and peripherally distributed, oral survival of motor neuron 2 (SMN2) premRNA splicing modifier approved by the EMA and MHRA for the treatment of patients aged ≥2 months, with a clinical diagnosis of Type 1, 2 or 3 spinal muscular atrophy (SMA) or 1–4 copies of SMN2.Safety data were pooled from three studies within the risdiplam clinical development programme:FIREFISH (NCT02913482) assesses safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of risdiplam in infants with Type 1 SMASUNFISH (NCT02908685) assesses safety, tolerability, PK, PD and efficacy of risdiplam in patients with Types 2/3 SMAJEWELFISH (NCT03032172) assesses safety, tolerability, PK and PD of risdiplam in patients who previously received RG7800 (RO6885247), nusinersen (SPINRAZA®), olesoxime or onasemnogene abeparvovec (ZOLGENSMA®).Pooled analyses from FIREFISH, SUNFISH and JEWELFISH showed no treatment-related safety findings leading to withdrawal from risdiplam in 465 patients treated for up to 38.9 months (data-cut-offs: 14 November 2019, 15 January 2020 and 31 January 2020, respectively). The differences in adverse event profiles between Type 1 and Types 2/3 SMA populations appeared to be driven by the severity of the underlying disease. Here we will present updated pooled safety analyses for the risdiplam studies.

Abstract
Risdiplam is a centrally and peripherally distributed oral survival of motor neuron 2 (SMN2) pre mRNA splicing modifier that increases the levels of functional SMN protein. Risdiplam (EVRYSDI™) has been approved by the US Food and Drug Administration for the treatment of patients with spinal muscular atrophy (SMA), aged 2 months and older. The risdiplam clinical development programme consists of four studies in a broad population of individuals with SMA.FIREFISH (NCT02913482) and SUNFISH (NCT02908685) are two-part studies assessing safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy in infants with Type 1 SMA and patients with Type 2/3 SMA, respectively. JEWELFISH (NCT0302172) assesses safety, tolerability, PK and PD in patients with SMA who previously received RG7800 (R06885247), nusinersen (SPINRAZA®), olesoxime or onasemno- gene abeparvovec-xioi (ZOLGENSMA®). RAINBOWFISH (NCT03779334) assesses efficacy, safety, PK and PD in infants with genetically diagnosed and presymptomatic SMA.Pooled analyses of FIREFISH and SUNFISH Parts 1 and 2 and JEWELFISH were conducted to determine the long-term safety profile of risdiplam. At the data-cut (15th January 2020) no treatment-related safety findings led to withdrawal from up to 39 months’ risdiplam treatment in 465 patients. Here we will present updated pooled safety analyses for the risdiplam studies.g.baranello@ucl.ac.uk

Abstract
AIM This Phase I, multicentre, open-label, non-randomised, parallel-group, two-part study aimed to evaluate the effect of mild to moderate hepatic impairment on the pharmacokinetics (PK), safety and tolerability of a single oral dose of risdiplam. METHODS Adult subjects (aged 18-70 years) with mild (Child-Pugh Class A; Part 1) or moderate (Child-Pugh Class B; Part 2) hepatic impairment were matched with subjects with normal hepatic function on sex, age, body mass index and smoking status. Each subject received a single oral dose of 5 mg risdiplam. Plasma concentrations of risdiplam and its metabolite M1 were measured, and PK parameters were compared. Adverse events, laboratory abnormalities, vital signs and electrocardiogram measurements were assessed. RESULTS After a single dose (5 mg) risdiplam, the risdiplam PK parameters area under the plasma concentration-time curve from time zero to infinity and maximum observed plasma concentration were approximately 20% and 5% lower, respectively, in subjects with mild hepatic impairment and approximately 8% and 20% higher, respectively, in subjects with moderate hepatic impairment compared with subjects with normal hepatic function. These differences were not statistically significant; all 90% confidence intervals for geometric least squares-means ratios spanned unity. No new risdiplam-related safety findings were observed in subjects with mild or moderate hepatic impairment. CONCLUSION Mild or moderate hepatic impairment did not have a clinically relevant impact on the PK of risdiplam. Therefore, no dose adjustment is required in patients with mild or moderate hepatic impairment when receiving risdiplam.

Abstract
OBJECTIVE Evaluation of ophthalmologic safety with focus on retinal safety in patients with spinal muscular atrophy (SMA) treated with risdiplam (EVRYSDI®), a survival of motor neuron 2 splicing modifier associated with retinal toxicity in monkeys. Risdiplam was approved recently for the treatment of patients with SMA, aged ≥ 2 months in the United States, and is currently under Health Authority review in the EU. METHODS Subjects included patients with SMA aged 2 months-60 years enrolled in the FIREFISH, SUNFISH, and JEWELFISH clinical trials for risdiplam. Ophthalmologic assessments, including functional assessments (age-appropriate visual acuity and visual field) and imaging (spectral domain optical coherence tomography [SD-OCT], fundus photography, and fundus autofluorescence [FAF]), were conducted at baseline and every 2-6 months depending on study and assessment. SD-OCT, FAF, fundus photography, and threshold perimetry were evaluated by an independent, masked reading center. Adverse events (AEs) were reported throughout the study. RESULTS A total of 245 patients receiving risdiplam were assessed. Comprehensive, high-quality, ophthalmologic monitoring assessing retinal structure and visual function showed no retinal structural or functional changes. In the youngest patients, SD-OCT findings of normal retinal maturation were observed. AEs involving eye disorders were not suggestive of risdiplam-induced toxicity and resolved with ongoing treatment. INTERPRETATION Extensive ophthalmologic monitoring conducted in studies in patients with SMA confirmed that risdiplam does not induce ophthalmologic toxicity in pediatric or adult patients with SMA at the therapeutic dose. These results suggest that safety ophthalmologic monitoring is not needed in patients receiving risdiplam, as also reflected in the United States Prescribing Information for risdiplam.

Abstract
AIMS Risdiplam (RG7916, RO7034067) is an orally administered, centrally and peripherally distributed, survival of motor neuron 2 (SMN2) mRNA splicing modifier for the treatment of spinal muscular atrophy (SMA). The objectives of this entry-into-human study were to assess the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics of risdiplam, and the effect of the strong CYP3A inhibitor itraconazole on the PK of risdiplam in healthy male volunteers. METHODS Part 1 had a randomized, double-blind, adaptive design with 25 subjects receiving single ascending oral doses of risdiplam (ranging from 0.6-18.0 mg, n = 18) or placebo (n = 7). A Bayesian framework was applied to estimate risdiplam's effect on SMN2 mRNA. The effect of multiple doses of itraconazole on the PK of risdiplam was also assessed using a two-period cross-over design (n = 8). RESULTS Risdiplam in the fasted or fed state was well tolerated. Risdiplam exhibited linear PK over the dose range with a multi-phasic decline with a mean terminal half-life of 40-69 h. Food had no relevant effect, and itraconazole had only a minor effect on plasma PK indicating a low fraction of risdiplam metabolized by CYP3A. The highest tested dose of 18.0 mg risdiplam led to approximately 41% (95% confidence interval 27-55%) of the estimated maximum increase in SMN2 mRNA. CONCLUSIONS Risdiplam was well tolerated and proof of mechanism was demonstrated by the intended shift in SMN2 splicing towards full-length SMN2 mRNA. Based on these data, Phase 2/3 studies of risdiplam in patients with SMA are now ongoing.

Abstract
BACKGROUND As recommended in the current prescribing information, rituximab infusions in patients with rheumatoid arthritis (RA) take 4.25 hours for the first infusion and 3.25 hours for subsequent infusions, which is a burden on patients and the health care system. We therefore evaluated the safety of infusing rituximab at a faster rate for an infusion period of 2 hours in patients with RA. METHODS Patients with an inadequate response to anti-TNF who were rituximab-naive or -experienced received 2 courses of rituximab: Infusion 1 (Day 1) was administered over the standard 4.25 hours, and Infusions 2 (Day 15), 3 (Day 168) and 4 (Day 182) were administered over a faster 2-hour period. The primary endpoint was incidence of infusion-related reactions (IRRs) associated with Infusion 2. RESULTS Of the 351 patients enrolled, 87% and 13% were rituximab-naive and -experienced, respectively. The incidence (95% CI) of IRRs associated with Infusion 1 was 16.2% (12.5%, 20.5%) and consistent with weighted historical incidence of 20.7% (19.4%, 22.1%). The incidence (95% CI) of IRRs associated with Infusions 2, 3, and 4 compared with respective weighted historical incidences at the standard infusion rate was 6.5% (4.1%, 9.7%) vs 8.1% (7.2%, 9.1%); 5.9% (3.5%, 9.3%) vs 11.5% (10.3%, 12.8%); and 0.7 (0.1%, 2.6%) vs 5.0% (4.2%, 6.0%), respectively. All IRRs were grade 1 or 2, except for 3 grade 3 IRRs associated with Infusion 1 and 2 grade 3 IRRs associated with Infusion 2. Four patients experienced a total of 5 grade 3 IRRs; 3 of these patients continued on to received subsequent infusions at the faster rate. There were no serious IRRs. CONCLUSION This study demonstrated that rituximab can be administered at the faster infusion rate at the second and subsequent infusions without increasing the rate or severity of IRRs.

Abstract
Blastomyces dermatitidis, a pathogenic fungal organism, is able to exist in two different morphologies, a multicellular mycelium or a unicellular yeast, according to temperature, 25 degrees C and 37 degrees C respectively. The switching between morphologies must be accompanied by a cascade of signaling events in which expression of genes responsible for the change of morphology is increased or decreased. bys1, a gene from B. dermatitidis isolate #58, is expressed at high levels in the unicellular yeast, but gradually diminishes as the temperature is lowered and the organism converts to the mycelial phase where there is no transcription of bys1. We explored if bys1 homologs are found in other B. dermatitidis isolates and if the transcription of the homologs were regulated by temperature. bys1 was identified in all B. dermatitidis isolates tested and could be grouped into two classes by Southern blot, PCR, and DNA sequence. Although the bys1 transcripts of both classes were regulated by temperature, transcription rates varied between the three isolates tested.

Abstract
Epitaxial lead titanate (PbTiO(3)) thin films on SrTiO(3) (100) substrate were grown in situ by radio-frequency sputtering for optical waveguiding applications. The crystalline quality of the PbTiO(3) films deposited at 550 degrees C has been investigated through x-ray diffraction analysis. It indicates that thin films are completely c-axis oriented (rocking curve FWHM of 0.2 degrees for the 001 reflection). The transmission spectrum method has been used to measure the dispersion of the refractive index. At 632.8 nm, the PbTiO(3) film with an (001) orientation exhibits a refractive index of 2.61, which represents 98% of the bulk material. The prism-coupling technique has been also employed to determine the optical attenuation in the planar waveguide. In this study, we report a low propagation loss of 2.2 ? 0.2 dB/cm obtained in a PbTiO(3) optical waveguide.

Abstract
Moclobemide is a reversible and selective inhibitor of monoamine oxidase subtype A with a wide spectrum of antidepressant activity. To fully evaluate product safety, Roche Drug Safety has collected data on adverse events (AEs), regardless of causality, from all sources worldwide through the product development phase and after launch. This effort has included analyses of reports from clinical trials, regulatory authorities, the literature, observational studies, and the marketplace. Roche Drug Safety has also carefully examined all cases where moclobemide was taken in overdose, whether with or without other substances. This article presents the safety profile of the product after 3 years on world markets. In clinical trials, moclobemide appeared only slightly less well tolerated than placebo. In comparative trials, moclobemide was largely devoid of the anticholinergic effects associated with tricyclic antidepressants. To the end of June 1993, with an estimated 780,000 subjects exposed, AEs had been reported by less than 0.2% of users. The most frequently reported AEs were psychiatric, neurologic, and gastrointestinal disorders. Hepatobiliary AEs were rare, suggesting that moclobemide is largely devoid of hepatotoxic potential. Cardiovascular AEs reflected the prevalence of cardiovascular disease in the population treated. This safety profile is largely unchanged from those observed at 1 and 2 years postlaunch, when the estimated exposed populations were 168,000 and 328,000, respectively. It is of great significance that the fatal toxicity index of moclobemide is zero. A review of single-drug intoxications with moclobemide at doses of up to 20.55 g revealed no deaths due solely to moclobemide overdose. All patients recovered fully within 1 to 7 days without residual hepatic or cardiovascular toxicity.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Tuberculosis (TB) is the most common opportunistic infection worldwide in human immunodeficiency virus (HIV)-infected patients. Intraabdominal TB includes lymphadenopathy and focal lesions of solid viscera. Symptomatic expression of tuberculous invasion of the pancreas (supplemented by demonstration of a mass on imaging) is rare among HIV-infected patients. We report the case of an HIV-infected patient with a tuberculous pancreatic abscess and review nine similar cases. All patients presented with persistent fever and abdominal pain. The diagnosis was made on the basis of detection of pancreatic mass lesions on computed tomographic (CT) scans and the results of cultures and/or acid-fast stains of peripancreatic abscess material and/or other body fluids. Despite an excellent response to antituberculous therapy, three patients died of unrelated causes. In the setting of a febrile illness with abdominal symptoms, tuberculous pancreatic abscess should be considered in the differential diagnosis for HIV-infected patients with a CT-identified mass lesion.

Abstract
The objectives of this study were to determine: 1) if the skin of mink might be a target organ for prolactin (PRL) by establishing if PRL binding sites (receptors) exist in the cell membranes of skin, and 2) if PRL receptor concentrations change during the onset and progression of the winter fur growth cycle. Skin was collected on October 6, 1992 for characterization of PRL receptors and from July through December 1992 (N = 3 mink/month) to evaluate possible changes in PRL receptor concentrations during the fur growth cycle. PRL receptors were quantified using 125I-oPRL in a validated radioreceptor assay. Scatchard analysis of saturation data revealed a single class of high-affinity (Kd = 5.21 x 10(-11) +/- .84 M), low capacity (Bmax = 27.03 +/- 3.37 fmoles/mg) binding sites. Only oPRL (40% displacement) and to a lesser extent oGH (3% displacement) inhibited the binding of 125I-oPRL to mink skin cell membranes. No inhibition of 125I-oPRL binding to membranes occurred in the presence of a 500-fold excess of bTSH or oLH, indicating that the receptors were hormone specific. Concentrations of 125I-oPRL receptors during the onset and development of winter fur growth (July through November) exhibited no significant change. However, following completion of the winter fur growth cycle (December 1) PRL receptor concentration was significantly higher than all preceding months. The greater binding observed at that time may reflect a change in tissue sensitivity, in preparation for growth of the summer pelage.(ABSTRACT TRUNCATED AT 250 WORDS)
