Article Synopsis
  • The PROPEL study compared a new therapy, cipaglucosidase alfa + miglustat (cipa + mig), to the standard treatment, alglucosidase alfa + placebo (alg + pbo), for adults with late-onset Pompe disease (LOPD).
  • An ongoing open-label extension study is assessing the long-term safety and effectiveness of cipa + mig, focusing on various outcome measures like walking distance and lung function.
  • After 104 weeks, patients on cipa + mig showed maintained improvements in walking distance and biomarkers with minimal safety concerns, indicating potential long-term benefits for those with LOPD.

Article Synopsis
  • Cipaglucosidase alfa plus miglustat (cipa + mig) is a new two-part treatment for Pompe disease, assessed in the Phase I/II ATB200-02 study over 48 months.
  • The study involved four adult groups, including both ambulating and non-ambulating patients, who received specific doses of cipa and mig biweekly.
  • Results showed improvements in walking distances and respiratory capacity, especially in ERT-naïve patients, with the treatment generally well tolerated and a safety profile similar to existing therapies.

Article Synopsis
  • This study investigates the genetic factors contributing to sarcoidosis susceptibility by examining novel alleles and the role of HLA (human leukocyte antigen) alleles in both European and African American populations.* -
  • A genome-wide analysis of 1335 sarcoidosis cases and 1264 controls from European descent, along with findings from an African American cohort, identified 49 significant SNPs (single nucleotide polymorphisms) linked to the disease.* -
  • The research highlights the importance of specific HLA alleles in the disease's development, noting significant associations between these genetic elements and sarcoidosis, reinforcing the idea that HLA class II genes play a critical role in the disease's pathogenesis.*

Psoriasis is a common inflammatory skin disorder that requires chronic treatment and is associated with multiple comorbidities. Guselkumab, a human immunoglobulin-G1-lambda monoclonal antibody, binds to interleukin-23 with high specificity and affinity and is effective in treating moderate to severe plaque psoriasis. As part of the guselkumab psoriasis clinical trial program, using a confirmatory approach, a population pharmacokinetics (PopPK) model was established using 13 014 PK samples from 1454 guselkumab-treated patients across 3 phase 2/3 trials.

Background: Significant advances have been made in the treatment of moderate-to-severe plaque psoriasis with biological therapies; however, these agents may not work equally in all populations.

Objectives: To evaluate the efficacy of guselkumab in patient subgroups with moderate-to-severe psoriasis from the pooled guselkumab VOYAGE 1 and VOYAGE 2 phase III studies.

Methods: Using data from the pooled VOYAGE 1 and VOYAGE 2 psoriasis studies, analyses were performed to evaluate the consistency of efficacy [Investigator's Global Assessment (IGA) 0/1 (cleared or minimal psoriasis) and IGA 0 (cleared)] across subpopulations defined by demographics, baseline disease characteristics and previous psoriasis treatment.

Purpose: The Psoriasis Symptoms and Signs Diary (PSSD) is a patient-reported instrument that assesses severity of six symptoms (itch, skin tightness, burning, stinging, and pain) and five signs (dryness, cracking, scaling, shedding/flaking, redness, and bleeding) of psoriasis.

Materials And Methods: PSSD symptoms and signs summary scores (range, 0-100) were derived based on individual item scores (0-10 [absent-worst imaginable]). Using Psoriasis Area and Severity Index [PASI], Investigator's Global Assessment [IGA] and Dermatology Life Quality Index [DLQI]) data from the NAVIGATE trial of patients with moderate-to-severe psoriasis, analyses were conducted to further validate the PSSD (7-day recall version) and establish criteria for clinically meaningful improvements (CMIs).

Ustekinumab, a human immunoglobulin G1 kappa (IgG1κ) monoclonal antibody that binds with high affinity to human interleukin (IL)-12 and IL-23, has been approved to treat patients with psoriasis. Guselkumab is a related human IgG1 monoclonal antibody in clinical development which specifically blocks IL-23. The objective of this study was to study the exposure-response relationship of guselkumab to guide dose selection for a Phase 2 study in patients with moderate-to-severe psoriasis.
