Matinas BioPharma Reports Second Quarter 2023 Financial Results and Provides a Business Update

FDA indicated that approval of MAT2203 as a first-line treatment for invasive aspergillosis will require an adequately powered study with an active control group and an all-cause mortality non-inferiority margin of 10%

FDA provided alternative trial designs which include the highest-need patients, aligning with growing positive treatment success in Matinas' Compassionate/Expanded Use Program as highlighted by a recent case update from Nationwide Children's Hospital

Internal RNAi programs demonstrate compelling in vitro activity; in vivo studies evaluating biological activity of LNC oral formulations of small oligonucleotides expected in second half of 2023

Conference call begins at 4:30 p.m. Eastern time today

BEDMINSTER, N.J., Aug. 09, 2023 (GLOBE NEWSWIRE) --  Matinas BioPharma (NYSE:MTNB), a clinical-stage biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology, reports financial results for the three and six months ended June 30, 2023 and provides a business update.

"Feedback we recently received from the U.S. Food and Drug Administration (FDA) underscores the challenges in developing novel antifungal therapies, with a high bar for efficacy, rigorously defined comparator groups and significant patient numbers for a first-line indication. Nevertheless, we are pleased that during our meeting earlier this year, the FDA recognized the need for a therapy like MAT2203, which is designed for patients with limited or no treatment options who require longer-term treatment," said Jerome D. Jabbour, Chief Executive Officer of Matinas. "Compassionate use cases both ongoing and completed represent powerful examples of the life-saving potential of MAT2203, and we remain committed to positioning this important drug for approval as quickly and efficiently as possible.

"We continue to refine the clinical development pathway to support registration of MAT2203, including the Limited Population Pathway for Antifungals (LPAD) Pathway, which we believe could require fewer patients. We plan to engage with the Biomedical Research and Development Authority (BARDA) as soon as possible to discuss next steps to fund MAT2203 through registration based on this feedback," he added.

Key Program Updates

MAT2203 (Oral Amphotericin B) Program 

FDA Feedback

• For a first-line treatment indication for invasive aspergillosis, the FDA recommended a 10% non-inferiority margin for an all-cause mortality endpoint, which would require approximately 700 patients in a 1:1 randomization against standard of care.
  
  
  
  
• The Company believes that MAT2203 could be an attractive option for those patients who are intolerant of azole therapy or have azole-resistant infections, which represents an important unmet medical need. The FDA provided alternative study designs for consideration, which include these highest need patients and which we believe could ultimately position MAT2203 for registration under the LPAD Pathway. This approach could require significantly fewer patients than required for first-line, unrestricted use.
  
  

Compassionate Use Program

• Eight patients have been enrolled in the Company's Compassionate/Expanded Use Access Program, with an additional case pending. In these eight enrolled patients, MAT2203 has successfully treated numerous types of invasive fungal infections at various locations in the body.   In addition to the compelling case presented earlier in 2023 at the European Congress of Clinical Microbiology and Infectious Disease (ECCMID), the following update was made available to the Company by the investigating physician: 
  
  
  
  Nationwide Children's Hospital
  
  
  
  
  • MAT2203 was used to treat a critically ill 15-year-old female patient with acute myeloid leukemia and diabetes who suffered from invasive fungal infections in sinus, lung, and brain due to multiple, extremely resistant mucor species, as well as aspergillus species. The patient was initially treated with IV liposomal amphotericin B but developed treatment-limiting electrolyte abnormalities and renal toxicity as well as significant feeding intolerance that required hospitalization for intravenous hydration and electrolyte supplementation. Upon enrolling in the Expanded Access Program, IV-amphotericin B was discontinued, and the patient began treatment with MAT2203 and was discharged from the hospital to continue the remainder of her treatment at home.
    
    
  • The patient began to show clinical improvement following only three weeks of therapy on MAT2203, renal function returned to normal and repeated sinus/brain MRI showed no evidence of active mucormycosis infection. Similarly, repeated chest CT showed a reduction in pulmonary nodules with no new lesions. The patient continued MAT2203 therapy for a total of 17 weeks with no evidence of nephrotoxicity.
  • "Our decision to switch this patient to MAT2203 proved to be a turning point in our patient's journey," commented Eunkyung Song, MD, Infectious Disease/Host defense program, Nationwide Children's Hospital. "Rapidly, her gastrointestinal intolerance and renal dysfunction resolved, enabling her to continue MAT2203 therapy for an additional three months. Throughout this period, the patient displayed excellent tolerance to MAT2203, and subsequent imaging revealed radiologic improvement in the invasive fungal infections. We are delighted with the remarkable outcome achieved with MAT2203, which addressed this patient's very challenging condition effectively."
    
    

LNC Platform Updates

Internal Small Oligonucleotide Program

• In vitro studies of LNC formulations of small oligonucleotides (including an RNAi therapy) conducted during the second and third quarters of 2023 demonstrated efficient intracellular delivery with measurable knockdown of certain inflammatory markers. Based on these results, Matinas is working with its partners to generate in vivo data evaluating biological activity with LNC oral formulations and expects initial data later in 2023. Successful demonstration of in vivo efficacy would represent a first for the oral delivery of small oligonucleotides.
  
  

National Resilience

• Matinas' collaboration with National Resilience continues to focus on in vitro and in vivo delivery of mRNA and expects initial data later in 2023.
  
  

Second Quarter Financial Results

The Company reported no revenue for the second quarter of 2023 compared with $1.1 million of revenue for the second quarter of 2022, which was generated from the Company's research collaborations with BioNTech SE.

Total costs and expenses for the second quarter of 2023 were $6.2 million compared with $7.0 million for the second quarter of 2022. The decrease was primarily attributable to lower manufacturing costs of clinical trial materials and a decrease in clinical trial consulting fees, partially offset by higher headcount.

The net loss for the second quarter of 2023 was $6.1 million, or $0.03 per share, compared with a net loss for the second quarter of 2022 of $5.9 million, or $0.03 per share.

Six Month Financial Results

Revenue for the first six months of 2023 and 2022 was $1.1 million. Total costs and expenses for the first half of 2023 was $12.8 million versus $14.7 million for the first half of 2022.

The net loss for the first six months of 2023 was $11.6 million, or $0.05 per share, compared with a net loss for the first six months of 2022 of $11.9 million, or $0.06 per share.

Cash, cash equivalents and marketable securities as of June 30, 2023 were $22.5 million compared with $28.8 million as of December 31, 2022. Based on current projections, the Company believes its cash position is sufficient to fund planned operations into the third quarter of 2024. The Company is seeking to extend its cash runway by securing non-dilutive funding from potential third-party development partners and government grant programs through agencies such as BARDA, as well as from proceeds from potential public or private equity offerings.

About Matinas BioPharma

Matinas BioPharma is a biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology.

Matinas' lead LNC-based therapy is MAT2203, an oral formulation of the broad-spectrum antifungal drug amphotericin B, which although highly potent, can be associated with significant toxicity. Matinas' LNC platform provides oral delivery of amphotericin B without the significant nephrotoxicity otherwise associated with IV-delivered formulations. MAT2203 also allows for safe, longer-term use outside of a hospital setting, which could have substantial favorable pharmacoeconomic impact. MAT2203 successfully completed the Phase 2 EnACT program in cryptococcal meningitis, meeting its primary endpoint and achieving robust survival. MAT2203 is being positioned for a single pivotal Phase 3 study in the treatment of aspergillosis and other invasive fungal infections, including mucormycosis, c. auris and other candidiasis, and certain endemic mycoses in patients with limited treatment options who are unable to be treated with azoles or echinocandins for reasons related to drug-drug interactions, resistance or for whom these antifungal agents are unable to be used for other clinical reasons.

In addition to MAT2203, preclinical and clinical data have demonstrated that this novel technology can provide solutions to many of the challenges standing in the way of achieving safe and effective intracellular delivery of both small molecules and larger, more complex molecular cargos such as RNAi, antisense oligonucleotides and vaccines. The combination of its unique mechanism of action and flexibility with routes of administration (including oral) positions Matinas' LNC technology to potentially become a preferred next-generation intracellular drug delivery platform.
