Recent Highlights

Lomecel-B™ for Hypoplastic Left Heart Syndrome (HLHS):

Announced achievement of exceeding 50% enrollment threshold for Phase 2 ELPIS II trial of Lomecel-B™ in HLHS.
Announced new long-term survival data from ELPIS I Trial of Lomecel-B™ for HLHS.
- Children in the ELPIS I trial had 100% survival up to five years of age after receiving Lomecel-B™ compared to approximate 20% mortality rate observed from historical control data.

Lomecel-B™ for Alzheimer's Disease:

In November 2022, Longeveron announced it had completed enrollment in its Phase 2a trial of Lomecel-B™ for the treatment of Alzheimer's disease (AD). The Phase 2a trial, called the CLEAR MIND trial, is a 48 patient, 4-arm, parallel design, randomized (1:1:1:1) clinical trial of Lomecel-B™ and is intended to evaluate the safety of a single and multiple infusions of two different dose levels compared to placebo in patients with mild AD. The primary endpoint is safety as measured by the occurrence of serious adverse events (SAEs) within the first 30 days after administration of Lomecel-B™. The secondary and exploratory endpoints include brain volumetry by magnetic resonance imaging (MRI), biomarkers relevant to inflammation and endothelial/vascular systems, and measures of cognitive function.
The Company expects to share top line results from CLEAR MIND by October 2023.

Lomecel-B™ for Aging-Related Frailty:

Enrollment continues in the Company's Phase 2 study evaluating Lomecel-B™ in patients with Aging-Related Frailty in Japan.
The Phase 2 clinical trial is a 3-arm, parallel design, randomized (1:1:1), placebo-controlled, double-blind infusion study of two different dose levels of Lomecel-B™. The trial is expected to enroll 45 patients and has a primary objective of evaluating the safety of Lomecel-B™ as a treatment for Aging-related Frailty.
The Phase 2 trial is being conducted in partnership with the National Center for Geriatrics & Gerontology (NCGG; Nagoya) and Juntendo University Hospital (Tokyo).
