BrainStorm Announces Presentations at June 2022 Scientific Conferences
Analyses accounting for ALSFRS-R floor effect in ALS yields new results to be presented at the ENCALS meeting in Edinburgh, Scotland
Clinical, biomarker and preclinical data from NurOwn® Phase 2 clinical trial in MS to be presented at CMSC meeting in National Harbor, MD, USA
NEW YORK, May 31, 2022 /PRNewswire/ -- BrainStorm Cell Therapeutics Inc. (NASDAQ: BCLI), a leading developer of cellular therapies for neurodegenerative diseases, today announces presentations at forthcoming ALS and MS scientific conferences in June 2022. Insights into the ALS Phase 3 primary endpoint leveraging ENCALS model patient prognosis trajectories will be presented as a scientific poster at the European Network to Cure ALS (ENCALS) meeting in Edinburgh, Scotland June 1-3, 2022. At the Consortium of Multiple Sclerosis Centers (CMSC) meeting in National Harbor, Maryland, June 1-4, 2022, Brainstorm will present three scientific posters describing NurOwn's effect on visual outcomes, and inflammatory CSF biomarkers from a Phase 2 trial, as well as data from an in vitro preclinical study evaluating the impact of concomitant use of Siponimod, an approved treatment for secondary progressive multiple sclerosis, on NurOwn neuroprotection.
ENCALS Meeting, Edinburgh Scotland:
Presentation Details: ALS Phase 3 NurOwn Trial: Insight into the primary outcome through ENCALS modeled trajectories
Presenter: Jonathan Katz MD, California Pacific Medical Center, San Francisco, CA USA
Date/Time: Thurs June 2, 17.00-18.30 BST
Conference Link: ENCALS
NurOwn's Phase 3 trial (BCT-002-US) included participants with advanced and rapidly declining ALS, making this trial subject to floor effects and reduced sensitivity of the clinical endpoint, the Revised ALS Functional Rating scale (ALSFRS-R). This presentation will summarize the clinical response on the primary endpoint this trial after applying two methods, ENCALS model and ALSFRS-R baseline value, to identify and minimize the impact of participant data most impacted by floor effects of the ALSFRS-R scale . Key findings:
- In participants predicted by the ENCALS model to have intermediate to very long survival, a treatment effect was observed.
- ENCALS model categories intermediate, long and very long, were less likely to be influenced by ALSFRS-R scale floor effect challenges.
- Clinical response on the primary endpoint in participants with either a high rate of decline (ALSFRS-R slope) and low baseline ALSFRS-R values, and with ENCALS model categories very short and short survival, may have been a misclassification due to the ALSFRS-R scale floor effect, which favored the placebo group in BCT-002.
In summary, the results confirm the importance of accounting for the floor effect in more advanced and rapidly declining ALS participants to potentially avoid misclassifying treatment responses.
CMSC 2022 Meeting, National Harbor MD, USA:
Presentation Details: NurOwn (MSC-NTF Cells) Phase 2 Clinical Trial in Progressive MS:
Effects on Monocular and Binocular Low Contrast Letter Acuity (LCLA) Outcomes
Presenter: Ralph Kern MD, MHSc, President and Chief Medical Officer, Brainstorm Cell Therapeutics.
Date/Time: Thursday June 2, 2022, 17:00- 19:00 ET
Conference Link: CMSC
This presentation evaluated the impact of NurOwn therapy on visual outcomes (monocular and binocular LCLA) in progressive MS study participants in an open-label Phase 2 clinical trial in progressive MS (NCT 03799718). The key findings were:
- We observed improvements in monocular and binocular LCLA (1.25% and 2.5% thresholds) at week 28 that were consistent with corresponding pre-specified responder outcomes (≥8 letter improvement)
- Matched patients from the long term CLIMB study and participants from the placebo arm of the SPRINT study showed worsening in LCLA over a similar time period
- Numerically larger LCLA improvements were seen at 1.25% threshold vs. 2.5% threshold and in monocular LCLA compared to binocular LCLA
In summary, this Phase 2 study of NurOwn therapy in progressive MS demonstrated encouraging results in monocular and binocular LCLA that should be further evaluated in a placebo-controlled clinical trial. This poster was nominated for an award at the CMSC meeting.
Presentation Details: NurOwn (MSC-NTF) Phase 2 Clinical Trial in Progressive MS: Effects on CSF Inflammatory Biomarkers
Presenter: Christopher Lock, MD PhD, Stanford School of Medicine.
Date/Time: Thursday June 2, 2022, 17:00- 19:00 ET
Conference Link: CMSC
In this scientific presentation, the effect of NurOwn treatment on CSF biomarkers in the Phase 2 clinical trial in progressive MS (NCT 03799718) is described. The key findings were:
- NurOwn treatment resulted in consistent reductions in CSF inflammatory biomarkers (OPN, sCD27, MCP-1and SDF-1a) that may be relevant to disease progression and treatment response in progressive MS.
- Associated with these positive inflammatory biomarker effects of NurOwn were improvements in a variety of functional outcomes.
In summary, these observations may guide future efforts to optimize this innovative autologous mesenchymal cellular therapy in progressive MS. This poster was nominated for an award at the CMSC meeting.
Presentation Details: NurOwn (MSC-NTF) Cells Maintain Neurotrophic and Immunomodulatory Effects with S1P Modulator Siponimod
Presenter: Sidney Spector MD PhD, Senior Vice President, Medical Affairs and Global Strategy, Brainstorm cell Therapeutics
Date/Time: Thursday June 2, 2022, 17:00- 19:00 ET
Conference Link: CMSC
This presentation describes the results of an invitro preclinical experiment evaluating the interaction of the S1P modulator Siponimod with MSC-NTF cell-induced neurite outgrowth in a human neuroblastoma cell line, and on the immunomodulatory effect on human activated peripheral blood mononuclear cells (PBMC).
MSC-NTF cells were able to induce neurite extension and inhibit inflammatory cytokine secretion, a finding that was not modified by co-culture with Siponimod, an S1P modulator recently approved for the treatment of secondary progressive MS (SPMS).
In summary, this suggests that co-administration of Siponimod does not interfere with known measures of MSC-NTF cell neuroprotection and immunomodulation and may guide future efforts to optimize this innovative autologous mesenchymal cellular therapy in progressive MS.
