MTNB Matinas Biopharma Holdings Inc

Matinas BioPharma Holdings, Inc. (NYSE American: 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, 2024 and provides a business update.

“We continue to engage in constructive partnership dialogues for MAT2203 and are pleased to announce that we have signed a non-binding term sheet for global licensing rights to this oral formulation of the potent, yet toxic antifungal amphotericin B,” said Jerome D. Jabbour, Chief Executive Officer of Matinas. “Since June, seven additional patients have gained access to oral MAT2203 in our Compassionate/Expanded Use Access Program with an additional six patients under evaluation. We are experiencing a dramatic increase in requests by physicians seeking access for their patients who have limited or no treatment options, which we attribute to the consistently positive clinical impact of MAT2203 in successfully treating a variety of deadly invasive fungal infections.

“Recent studies have increased our understanding of the potential for our LNC platform in delivering both small oligonucleotides and small molecule oncology drugs, including LNC cellular uptake and cargo delivery,” he added. “We continue to expand our knowledge base and are evaluating the next best steps for this technology as we determine how to maximize return to shareholders. We expect to be in a better position to provide additional guidance following the consummation of a MAT2203 partnership.”

Key Program Updates

MAT2203 (Oral Amphotericin B)

• Matinas signed a non-binding term sheet with a single partner for global licensing rights to develop, manufacture and commercialize MAT2203 for all future treatment indications, including the intended initial indication of treatment for patients with invasive aspergillosis with limited or no other treatment options. Preparations are ongoing to enable the initiation of the ORALTO Phase 3 registration trial of MAT2203 to commence as soon as possible following a successful partnership announcement.

• Under the Compassionate/Expanded Use Access Program, 31 patients with a variety of serious and even life-threatening invasive fungal infections with limited or no other treatment options have been provided access to oral MAT2203, and 6 additional requests are under evaluation. Importantly, 7 patients have been or are being treated for invasive aspergillosis, each with positive results.

• Of the 15 patients in the Compassionate/Expanded Use Access Program who have completed treatment with MAT2203 (median treatment of 16 weeks with a range of 2 to 49 weeks), 8 had a complete response and 7 were improved. Response to treatment was assessed by the treating physician. Nine additional patients are continuing to receive longer-term treatment with positive ongoing effects and 5 have just recently initiated treatment. To date, only 2 patients have discontinued MAT2203 in this program, both occurring during the first week of treatment, with one due to an intolerance and the other due to a terminal condition not otherwise related to the underlying fungal infection.

LNC Platform

• Following early success in melanoma, recent additional in vivo studies in animal breast, prostate and lung cancer models have demonstrated varying degrees of tumor growth inhibition with daily oral dosing of LNC-docetaxel. Additionally, daily oral LNC-docetaxel in combination with intravenous docetaxel demonstrated greater degrees of tumor inhibition, but also resulted in additional weight loss. Additional studies are evaluating several strategies to potentially improve the therapeutic index of docetaxel.

• An LNC formulation of an additional chemotherapeutic agent, miriplatin, a highly toxic agent only approved outside the U.S. for intra-arterial use, demonstrated strong cellular uptake and tumor cell-killing capabilities in vitro in testing conducted during the second quarter. More recent in vivo testing showed the oral LNC formulation of miriplatin as very effective in reducing tumor sizes with significant weight loss also observed.

• A series of in vitro studies was recently completed investigating potential relationships between the amount of surface phosphatidylserine (PS) and the extent of LNC uptake into certain tumor cells. Based upon these studies, surface PS expression appears to be one, but not the only, driving factor for cellular uptake. Additional work is ongoing to better understand and predict the efficacy of LNC-delivered chemotherapeutics.

• Following early encouraging in vivo data demonstrating the successful oral delivery, biological activity, and potential therapeutic efficacy of two different LNC-formulated small oligonucleotides targeting inflammatory cytokines IL-17A and TNFα, more recent follow-up in vivo studies of orally administered LNC-formulated small oligonucleotides have been less consistent in showing therapeutic efficacy in certain inflammatory conditions. Additional optimization is required prior to identifying a potential product candidate.

Second Quarter Financial Results

The Company reported no revenue for the second quarters of 2024 and 2023.

Total costs and expenses for the second quarter of 2024 were $5.8 million, compared with $6.2 million for the second quarter of 2023. The decrease was primarily due to lower clinical development expenses, personnel costs and administrative expenses.

The net loss for the second quarter of 2024 was $5.7 million, or $0.02 per share, compared with a net loss for the second quarter of 2023 of $6.1 million, or $0.03 per share.

Six Month Financial Results

The Company reported no revenue for the six months ended June 30, 2024, compared with $1.1 million for the six months ended June 30, 2023, which was generated from research collaborations with BioNTech SE and Genentech Inc.

Total costs and expenses for the first six months of 2024 were $11.7 million, compared with $12.8 million for the first six months of 2023.

The net loss for the first six months of 2024 was $11.5 million, or $0.05 per share, compared with a net loss for the first six months of 2023 of $11.6 million, or $0.05 per share.

Cash, cash equivalents and marketable securities as of June 30, 2024, were $14.3 million, compared with $13.8 million as of December 31, 2023. In April 2024, the Company raised gross proceeds of $10.0 million through a registered direct offering.

About Matinas BioPharmaMatinas 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. Combining comparable fungicidal activity with targeted delivery results in a lower risk of toxicity and potentially creates the ideal antifungal agent for the treatment of invasive fungal infections. MAT2203 was successfully evaluated in the completed Phase 2 EnACT study in HIV patients suffering from cryptococcal meningitis, meeting its primary endpoint and achieving robust survival. MAT2203 will be further evaluated in a single Phase 3 registration trial (the “ORALTO” trial) as an oral step-down monotherapy following treatment with AmBisome® (liposomal amphotericin B) compared with the standard of care in patients with invasive aspergillosis who have limited treatment options.

In addition to MAT2203, preclinical and clinical data have demonstrated that this novel technology can potentially provide solutions to many challenges of achieving safe and effective intracellular delivery of both small molecules and larger, more complex molecular cargos including small oligonucleotides such as ASOs and siRNA. 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 orally available intracellular drug delivery platform.
