DURHAM, N.C., Nov. 09, 2023 (GLOBE NEWSWIRE) -- Humacyte, Inc. (NASDAQ:HUMA), a clinical-stage biotechnology platform company developing universally implantable, bioengineered human tissue at commercial scale, today announced financial results for the third quarter ended September 30, 2023 and highlighted recent corporate accomplishments advancing the investigational, universally implantable Human Acellular Vessel (HAV) closer to planned U.S. market launch.

"The major milestones reached during the third quarter of 2023 set the stage for our planned Biologics License Application (BLA) filing of the HAV for the vascular trauma indication with the U.S. Food and Drug Administration (FDA) in the fourth quarter of 2023," said Laura Niklason, M.D., Ph.D., Chief Executive Officer of Humacyte. "A key event supporting the planned BLA filing was our announcement of positive top line results from the V005 trial in vascular trauma repair. We are also proud that our humanitarian efforts in Ukraine, which will supplement the V005 results in our BLA filing, have resulted in successful outcomes including saving lives and limbs in a wartime setting. Finally, we are pleased that the potential of the HAV pipeline has also been observed in other clinical studies this quarter, including the presentation of Phase 2 results in severe peripheral arterial disease (PAD). In addition, we recently published preclinical results of our small caliber HAV in a juvenile heart disease model. The remainder of 2023 will be exciting, and we thank the medical professionals, patients, researchers and employees for their contribution to the advancement of the HAV."

Third Quarter 2023 Corporate Highlights

Clinical and Regulatory Updates

Positive Phase 2/3 Trauma Results – In September 2023, Humacyte announced positive top line results from its V005 Phase 2/3 trial of the HAV in vascular trauma repair. In this single-arm clinical trial, the HAV had higher rates of patency, and lower rates of amputation and infection, compared to historic synthetic graft benchmarks. A total of 69 patients were enrolled in the V005 trial, of which 51 had vascular injury of the extremities and comprised the primary evaluation group for the study. The 30-day patency (presence of blood flow) for the HAV in the clinical trial was 90.2% for the extremity patients compared to approximately 81% historically reported for synthetic grafts. The HAV demonstrated lower amputation rates, with a rate of 9.8% compared to over 20% historically reported for synthetic grafts. The HAV also demonstrated lower rates of infection, with a rate of 2.0% compared to over 8% historically reported for synthetic grafts.
Planned BLA Filing this Quarter – Humacyte plans to file a BLA for the HAV for the treatment of vascular trauma with the FDA during the current quarter.

Presentations and Publications

Upcoming Presentations at a Major Vascular Surgery Symposium – Multiple presentations are expected to be made at the VEITH Symposium, a major vascular surgery meeting, in New York City on November 15-18, 2023. These include an expanded presentation of the results of the V005 vascular trauma trial, and the outcome of research which seeks to identify which dialysis patients experience the most difficulties with their dialysis access, and which patients may most benefit from an access that is durable and resists infection.
Publication of Preclinical Results in Juvenile Heart Disease Study – In October 2023, a publication in the Journal of Thoracic and Cardiovascular Surgery described a preclinical study showing the potential for the investigational small-diameter HAV to treat tetralogy of Fallot, a heart condition that affects one in every 2,000 babies born each year. In the preclinical study, researchers from Nationwide Children's Hospital (Columbus, OH) and Humacyte implanted 3.5mm diameter HAVs into a juvenile large-animal model of pediatric heart disease. The 3.5mm HAVs remained patent for up to six months, and evidence of HAV repopulation by host cells was observed, similar to what has been observed in human patients. This study also demonstrates the extension of Humacyte's manufacturing platform, adding production of the 3.5mm vessels in the same manufacturing platform used to produce Humacyte's 6 mm HAVs that are in current clinical use.
Presentation of Results from Phase 2 Study in PAD – In September 2023, results were presented from an FDA-regulated, investigator-sponsored clinical study conducted at the Mayo Clinic of the HAV in patients with chronic limb-threatening ischemia, the end stage of peripheral artery disease (PAD). In the presentation at the Midwestern Vascular Conference in Minneapolis, MN, researchers observed that in the clinical study the HAV was a safe, resilient, and effective conduit for arterial bypass and limb salvage. This is an important result since approximately 40% of patients requiring lower extremity bypass do not have saphenous vein available, which is the standard of care for treating this challenging disease state.
Presentation of Success in Treating Wartime Injured in Ukraine – Results of the real-world use of the HAV under the humanitarian aid program to treat war-induced vascular trauma injuries in Ukraine were presented in August at the 2023 Military Health System Research Symposium (MHSRS) in Kissimmee, Florida. The 19 patients treated under the program suffered from a range of traumatic injuries, including gunshots, shrapnel, blast injuries and accidents. Clinicians reported that the rate of success in treating patients with the HAV was high, with an observed 30-day HAV patency of 95%, 30-day limb salvage of 100%, 30-day survival of 100%, and zero cases of infection of the HAV. Ukrainian clinicians concluded that the HAV has the potential to offer combat surgical teams an off-the-shelf and universally implantable therapy that is resistant to infection, potentially offering durable performance to military personnel and helping with limb salvage. Results from the Ukraine program will be included in Humacyte's planned BLA filing with the FDA.
Publication Supporting Infection Resistance of HAV – In July 2023, a preclinical study demonstrated a possible scientific basis for the low rates of infection that have been observed in clinical trials of the HAV. The report was published in the Journal of Vascular Surgery – Vascular Science. This work compared the infection resistance of the HAV to synthetic polytetrafluorethylene (ePTFE) grafts, which are made of plastic. The laboratory results suggest that the bioengineered human tissue of the HAV may have superior compatibility with the body's own white blood cells as compared to ePTFE. While human white blood cells die when they come in contact with ePTFE, the cells survive and function in contact with the HAV material, which may improve the ability of the HAV to fight dangerous infections once implanted in the body.

The HAV is an investigational product and has not been approved for sale by the FDA or any other regulatory agency.

Third Quarter 2023 Financial Highlights

The Company reported cash and cash equivalents of $100.0 million as of September 30, 2023. In May 2023, Humacyte reported the completion of a funding arrangement of up to $160 million with Oberland Capital Management, $40 million of which has been received. Total net cash used was $49.4 million for the first nine months of 2023, compared to $53.8 million for the first nine months of 2022. Humacyte believes that its cash and cash equivalents and expected funding from the Oberland arrangement are adequate to finance operations past the currently anticipated timelines for FDA approval and commercialization of the HAV in the vascular trauma indication.
There was no revenue for the third quarter of 2023 and nine months ended September 30, 2023. Revenue was $31 thousand for the third quarter of 2022 and $1.6 million for the nine months ended September 30, 2022. Revenue for 2022 was related to a grant supporting the development of the HAV.
Research and development expenses were $18.6 million for the third quarter of 2023, compared to $17.3 million for the third quarter of 2022, and were $56.4 million for the nine months ended September 30, 2023, compared to $48.3 million for the nine months ended September 30, 2022. The current-period increases resulted primarily from increased personnel and external services expenses to support expanded research and development initiatives and our clinical trials, including preparation for the HAV vascular trauma trial completion and planned BLA filing for the vascular trauma indication, and expansion of clinical development of the HAV in AV access for hemodialysis.
General and administrative expenses were $6.1 million for the third quarter of 2023, compared to $6.2 million for the third quarter of 2022, and were $17.5 million for the nine months ended September 30, 2023, compared to $17.1 million for the nine months ended September 30, 2022. The increase during the nine months ended September 30, 2023 compared to the prior-year period resulted primarily from increased personnel costs, primarily driven by preparation for the planned commercial launch of the HAV in the vascular trauma indication. The slight decrease during the third quarter of 2023 compared to 2022 resulted primarily from a decrease in external services and professional fees, partially offset by an increase in personnel expenses.
Other net income (expense) was net expense of $1.4 million for the third quarter of 2023, compared to net expense of $1.8 million for the third quarter of 2022, and other net expense of $11.8 million for the nine months ended September 30, 2023, compared to other net income of $55.5 million for the nine months ended September 30, 2022. The decrease in other net expense for the third quarter of 2023 compared to 2022 resulted primarily from an increase in interest income due to rate increases. The increase in other net expense for the nine months ended September 30, 2023 compared to 2022, resulted primarily from the non-cash remeasurement of the contingent earnout liability associated with the August 2021 merger with Alpha Healthcare Acquisition Corp.
Net loss was $26.0 million for the third quarter of 2023, compared to $25.3 million for the third quarter of 2022, and net loss was $85.7 million for the nine months ended September 30, 2023, compared to $8.2 million for the nine months ended September 30, 2022. The current-period increases in net loss resulted from the non-cash remeasurement of the contingent earnout liability, and increased operating expenses, described above.
