Brain atrophy measurement can provide an estimate of the amount of tissue destruction due to the pathologic processes in multiple sclerosis. The potential usefulness of atrophy as a marker of disease progression depends upon the concurrent and predictive relationships between atrophy and disability. A follow-up study was performed to measure atrophy and disability scores in patients from the Multiple Sclerosis Collaborative Research Group's phase III trial of IFNb-1a (Avonex) in relapsing-remitting multiple sclerosis. New data were obtained on 160 out of 172 eligible patients from the original trial were enrolled in the follow-up study approximately 8 years after randomization. The follow-up visit consisted of several tests and questionnaires including a clinical exam to determine Expanded Disability Status Score (EDSS) and Multiple Sclerosis Functional Composite (MSFC), and a magnetic resonance imaging exam to calculate the brain parenchymal fraction. Brain parenchymal fraction was correlated with both EDSS and MSFC at each of the four time points for which data were available (baseline 1, 2 and 8 years). Furthermore, the change in BPF was correlated with the changes in disability scores from the end of the phase III trial to the follow-up exam. These data suggest that brain atrophy may be a useful and clinically relevant marker of disease progression in relapsing-remitting MS.

Using MRI, we measured disease activity and brain atrophy in nine multiple sclerosis patients treated with autologous hematopoietic stem cell transplantation (AHSCT) for a mean follow up of 63 months. We show that AHSCT is associated to a longlasting suppression of inflammation and to a marked decrease of the rate of brain atrophy after the second year following treatment.

Background To investigate in a large cohort of patients with multiple sclerosis (MS), lesion load and atrophy evolution, and the relationship between clinical and magnetic resonance imaging (MRI) correlates of disease progression. Methods Two hundred and sixty-seven patients with MS were studied at baseline and two years later using the same MRI protocol. Abnormal white matter fraction, normal appearing white matter fraction, global white matter fraction, gray matter fraction and whole brain fraction, T2-hyperintense, and T1-hypointense lesions were measured at both time points. Results The majority of patients were clinically stable, whereas MRI-derived brain tissue fractions were significantly different after 2 years. The correlation between MRI data at baseline and their variation during the follow-up showed that lower basal gray matter atrophy was significantly related with higher progression of gray matter atrophy during follow-up. The correlation between MRI parameters and disease duration showed that gray matter atrophy rate decreased with increasing disease duration, whereas the rate of white matter atrophy had a constant pattern. Lower basal gray matter atrophy was associated with increased probability of developing gray matter atrophy at follow-up, whereas gray matter atrophy progression over 2 years and new T2 lesion load were risk factors for whole brain atrophy progression. Conclusions In MS, brain atrophy occurs even after a relatively short period of time and in patients with limited progression of disability. Short-term brain atrophy progression rates differ across tissue compartments, as gray matter atrophy results more pronounced than white matter atrophy and appears to be a early phenomenon in the MS-related disease progression.

Background: Oxidative stress plays an important role in multiple sclerosis (MS). Isoprostanes are biomarkers for oxidative stress and have been related to neurological disease progression. Objective: To study whether plasma isoprostane levels were related to disease progression in MS. Methods: Plasma levels of 8,12-iso-iPF2alpha-VI were determined in 17 patients with clinically isolated syndrome (CIS), 41 relapsing–remitting MS (RRMS) patients and 5 primary progressive MS (PPMS) patients and related to MRI and clinical disease parameters. Results: Isoprostane levels were similar in CIS (60.9, interquartile range (IQR): 47.7–77.7 pg/ml) and RRMS patients (65.3, IQR: 51.9–82.8 pg/ml). The plasma levels were lower in PPMS patients (42.5, IQR: 37.1–49.9) pg/ml, p<0.05) compared to CIS and RRMS patients in this cohort, which was not confirmed in a second cohort. Baseline isoprostane levels were not related to clinical progression defined by conversion form CIS to RRMS or change in Expanded Disability Status Scale (EDSS) or MS Functional Composite (MSFC) scores during six years of follow-up (CIS + RRMS), nor to change in volume of gadolinium enhancing lesions, T2 lesion load or T1 hypointense lesion load during 2.8 years of follow-up (CIS + RRMS). Conclusion: These results do not support a strong role of 8,12-iso-iPF2alpha-VI in the prediction of disease progression in MS.

578 Background: SB3 was approved in the US and EU as a biosimilar of reference trastuzumab (TRZ). Here, we report 4-year cardiac safety and survival outcomes. Methods: After completing neoadjuvant-adjuvant therapy in patients with HER2 positive early breast cancer, patients from selected countries participated in a 5-year follow-up study of a phase III trial (Pivot et al. Eur J Cancer 2019). The aim was to observe long-term cardiac safety and survival. EFS and OS were analyzed in subgroups by ADCC status within TRZ in ad-hoc analyses. Results: Of 875 patients randomized in the phase III trial, 367 patients (SB3, N=186; TRZ, N=181) were enrolled in the follow-up study. The median follow-up was 53 months. During the follow-up, the incidence of asymptomatic significant left ventricular ejection fraction (LVEF) decrease was low (SB3, n=1; TRZ, n=2), with all patients recovering with LVEF ≥ 50%. No cases of symptomatic congestive heart failure, cardiac death, or other significant cardiac condition were reported. 4-year EFS rates were 83.4% for SB3 and 80.7% for TRZ with a HR of 0.77 [95% CI 0.47, 1.27]. 4-year OS rates were 94.3% for SB3 and 89.6% for TRZ with a HR of 0.53 [95% CI 0.24, 1.16]. From ad-hoc analysis, a difference in EFS and OS was seen between Non-drifted TRZ and Drifted TRZ; Difference between SB3 and Non-drifted TRZ was not statistically significant. Conclusions: In a subset of patients from the phase III trial, comparable long-term cardiac safety and survival at 4-year supports biosimilarity between SB3 and TRZ. Ad-hoc analysis results by ADCC status suggest a possible correlation between ADCC and clinical efficacy. Further follow-up is needed. Clinical trial information: NCT02771795 . [Table: see text]
