Tumor Location of Uveal Melanoma and Impact on Metastasis-Free Survival in 1001 Cases. (PubMed, Semin Ophthalmol) - "Uveal melanoma in the central region was smaller in thickness and base and demonstrated more favorable MFS compared to other quadrants, clock hours, and anteroposterior zones. Analysis of the 49 zones showed no benefit of tumor location alone after adjusting for tumor size and proximity to foveola and optic disc."

Subgroup and Subdomain Analysis of Patients with Long Term Follow-Up In a Phase III, Randomized, Placebo-Controlled Crossover Trial with Levacetylleucine (IB1001) for Niemann-Pick Disease Type C (AAN 2025) - "Levacetylleucine demonstrated a significant improvement over placebo in pediatric and adult patients on the SARA and consistent improvement across mDRS subdomains. Treatment with levacetylleucine after 18 months was associated with a clinically significant reduction in disease progression consistent with a neuroprotective and disease-modifying effect."

SARA Eight-Item Subgroup Analysis of N-acetyl-L-leucine for Niemann-Pick Disease Type C (AAN 2025) - "The IB1001-301 clinical trial was a Phase III, double-blind, randomized, placebo-controlled cross-over trial comparing NALL with placebo for treating neurological signs and symptoms in NPC.SARA is a validated eight-item clinical rating scale that incorporates assessments of gait, stance, sitting, speech disturbance, finger-chase, nose-to-finger, fast-alternating-hand movements, and heel-along-shin slide.Design/Patients received treatment with orally administered NALL 2-3 times per day as weight-based dosing...Analysis of the SARA subdomains demonstrated consistent improvement across each domain and the associated functional area—including ambulation, postural balance, speech, fine motor skills, and upper and lower extremity function. There was a consistent improvement with NALL versus placebo demonstrating the positive effects of NALL across a broad range of neurological functions."

Medexus Announces Strong Fiscal Q2 2025 Results (Medexus Pharma Press Release) - "IXINITY (US): Unit demand in the United States decreased by 4% over the trailing 12-month period ended September 30, 2024. (Source: customer-reported dispensing data.) Demand continues to reflect the effects of lower observed average quantities of IXINITY consumed by newer patients and a greater than expected impact of other developments in the broader hemophilia B treatment solutions market specifically relating to greater availability and use of extended half-life products that compete with IXINITY. Medexus will continue seeking to maintain existing demand, and to improve management of product supply to the market primarily by means of an August 2024 agreement with a national operator of specialty pharmacies. Medexus's investments in its IXINITY manufacturing process improvement initiative have had a positive impact on batch yield and manufacturing costs over fiscal year 2024 and now extending into fiscal year 2025."

Long-Term Effects of Empagliflozin in CKD (KIDNEY WEEK 2024) - "Over the entirety of follow-up a primary outcome occurred in 865/3304 participants (26.2%) in the empagliflozin group and in 1001/3305 (30.3%) in the placebo group (HR=0.79, 95%CI 0.72-0.87). EMPA-KIDNEY PTFU quantifies more completely the total effects of the short period of 2 years of empagliflozin. Study empagliflozin continued to exert benefit on cardiorenal outcomes for a period after its discontinuation. The post-trial benefit was smaller than the benefit when taking study treatment and appeared to be temporary."

Metastasis-free survival of uveal melanoma by tumour size category based on The Cancer Genome Atlas (TCGA) classification in 1001 cases. (PubMed, Clin Exp Ophthalmol) - "By tumour size category, favourable cytogenetics (Groups A or B) is found in 86% of small tumours, 60% of medium tumours, and 58% of large tumours. The MFS at 10 years for favourable cytogenetics was 98% for small tumours, 92% for medium tumours, and 54% for large tumours. Tumour size category can serve as a surrogate for TCGA."

Assessment of the reliability, responsiveness, and meaningfulness of the scale for the assessment and rating of ataxia (SARA) for lysosomal storage disorders. (PubMed, J Neurol) - "Qualitative and quantitative data demonstrate the reliability and responsiveness of the SARA score as a valid measure of neurological signs and symptoms in LSDs with CNS involvement, such as NPC and GM2 Gangliosidoses. A 1-point change represents a clinically meaningful transition reflecting the gain or loss of complex function."

Results of a Phase III, Randomized, Placebo-controlled Crossover Trial with N-acetyl-L-leucine for Niemann-Pick Disease Type C (AAN 2024) - P3 | "The secondary endpoints (CGI, SCAFI, mDRS) were also improved with IB1001 as compared to placebo (p<0.001)...NALL demonstrated a statistically significant improvement over placebo with a clinically meaningful benefit in symptoms (motor and cognitive), functioning, cognition, and quality of life. NALL was safe and well-tolerated, providing a favorable benefit-risk profile for the treatment of NPC."
