Matinas BioPharma Successfully Reaches Agreement with FDA for a Single Phase 3 Registration Trial to Support an NDA for MAT2203 for the Treatment of Invasive Aspergillosis
- None.
- None.
The announcement of Matinas BioPharma's alignment with the FDA on the ORALTO Phase 3 trial design for MAT2203 represents a pivotal step in the drug's development pathway. MAT2203's potential as an all-oral therapy for invasive aspergillosis, a serious infection caused by Aspergillus fungi, could address a significant unmet medical need, particularly for patients with limited treatment options. The focus on a non-inferiority trial comparing MAT2203 to AmBisome® sets a clear benchmark for efficacy, with the primary endpoint of all-cause mortality at day 42 providing a quantifiable and clinically meaningful measure of success.
From a research perspective, the key secondary endpoint assessing treatment-related toxicities is also noteworthy. Superiority in reducing toxicities could imply that MAT2203 offers a safer profile compared to existing treatments, which can be crucial for patient compliance and quality of life. Additionally, the previous success in the Phase 2 EnACT trial and the Compassionate/Expanded Use Access Program may lend credence to the anticipated efficacy and safety of MAT2203 in a broader patient population.
Matinas BioPharma's progress in the clinical development of MAT2203 is likely to be closely monitored by investors and potential partners. The therapeutic market for invasive fungal infections, while niche, is characterized by high-need and often high-cost treatments. The company's emphasis on a lipid nanocrystal (LNC) platform delivery technology could differentiate MAT2203 from other treatments and potentially offer a competitive advantage in terms of efficacy, safety and patient adherence.
Moreover, the CEO's mention of advancing partnership discussions indicates strategic movement towards commercialization, which could have significant implications for the company's financial health and stock performance. The market's response to this news will hinge on perceived clinical success probability, the attractiveness of MAT2203's market potential and the strength of Matinas' partnership strategy.
Entering a Phase 3 trial is a capital-intensive phase for any biopharmaceutical company and this step by Matinas BioPharma could impact its financial position. The company's alignment with the FDA suggests a streamlined regulatory pathway, potentially reducing the risk and uncertainty typically associated with drug development. This could be positively reflected in the company's valuation.
Investors should consider the implications of trial costs, cash burn rate and the need for additional funding, which might lead to dilution if the company opts to raise capital through equity. The potential for securing a partnership could alleviate some financial pressures and provide non-dilutive funding, but it also introduces dependencies on the terms and success of such agreements. The outcome of the ORALTO trial will be critical in determining the long-term financial impact on Matinas BioPharma, including the potential for milestone payments, royalty structures and market share in the antifungal space.
ORALTO Phase 3 trial focused on desired initial target indication of early oral step-down treatment of invasive aspergillosis infections in adults who have limited or no treatment options
Non-inferiority trial will enroll approximately 216 patients with primary endpoint of all-cause mortality at day 42
Key secondary endpoint includes superiority of oral step-down treatment with MAT2203 vs. AmBisome® (liposomal amphotericin B) for treatment-related toxicities leading to changes in treatment
BEDMINSTER, N.J., Feb. 20, 2024 (GLOBE NEWSWIRE) -- Matinas BioPharma (NYSE American: MTNB), a clinical-stage biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology, announces alignment with the U.S. Food and Drug Administration (FDA) on the design of a single Phase 3 registration trial of MAT2203 in patients with invasive aspergillosis who have limited treatment options (the “ORALTO” trial).
The ORALTO trial design is built upon the successful Phase 2 EnACT trial that confirmed MAT2203’s efficacy and safety as a step-down and all-oral therapy in HIV patients with cryptococcal meningitis, as well as the Company’s ongoing Compassionate/Expanded Use Access Program in individuals suffering from severe invasive fungal infections with no other treatment options.
“We are pleased to achieve alignment with the FDA on the design of a single Phase 3 trial to support the registration of MAT2203 for the treatment of invasive aspergillosis in patients with limited treatment options,” commented Dr. Theresa Matkovits, Chief Development Officer at Matinas. “We greatly appreciate the opportunity to work collaboratively with the FDA, which was essential for reaching consensus on all critical elements of the registrational path for MAT2203. Importantly, we view ORALTO as a registration trial with a high probability of clinical success given the ongoing positive patient clinical experience in our Compassionate/Expanded Use Access Program, which mirrors the patients to be enrolled in our upcoming Phase 3 registration trial.”
“Reaching this agreement with the FDA is a major milestone for Matinas and a testament to the dedication and expertise of our collective team,” added Jerome D. Jabbour, Chief Executive Officer of Matinas. “We are energized by the support and guidance from the FDA, and believe this alignment provides the requisite certainty to advance our partnership discussions for this important product. We are pursuing every opportunity to secure a partner and to advance MAT2203 into this Phase 3 registration trial as quickly as possible.”
About ORALTO
ORALTO is a Phase 3, randomized, multicenter, open-label, adjudicator-blinded study to evaluate the efficacy and safety of MAT2203 as an oral step-down treatment following treatment with AmBisome (liposomal IV-amphotericin B) compared with the standard of care in patients with invasive aspergillosis who have limited treatment options. The primary efficacy endpoint is all-cause mortality at study day 42. Key secondary objectives include:
(a) demonstration of superiority of oral-step down treatment with MAT2203 compared with AmBisome for treatment-related toxicities leading to changes in treatment (i.e., dose adjustment/discontinuations or changes to treatment regimens);
(b) long-term survival benefit of MAT2203 using all-cause mortality at study day 84;
(c) evaluation of the impact of MAT2203 on healthcare resource utilization and quality of life impact.
Enrollment is expected to include approximately 216 adults with recently diagnosed probable or proven invasive aspergillosis who are being treated with AmBisome due to their inability to receive an IV mold-active azole and with limited alternative treatment options. Following up to two days of initial treatment with AmBisome, eligible study participants will be entered into the study and randomized in a 2:1 ratio to receive either oral MAT2203 or continued AmBisome treatment followed by standard of care.
All study participants will receive up to 12 weeks of treatment starting from the first day of treatment with AmBisome. It is anticipated that all study participants will be hospitalized during the initial AmBisome treatment period. After step-down to oral MAT2203, study participants may be discharged from the hospital to continue treatment on an outpatient basis, as clinically appropriate.
An independent Data Review Committee, who will be blinded to treatment, will adjudicate primary and secondary endpoints, including clinical, radiological, and mycological responses. Once approximately
ORALTO will be a global trial conducted at approximately 65 investigator sites in the U.S., Europe, South America, Middle East, and Asia Pacific. Enrollment is expected to commence in the second half of 2024 and is expected to require approximately 24 months.
About Invasive Aspergillosis in Patients with Limited Treatment Options
Invasive aspergillosis (IA) is a serious and life-threatening invasive fungal infection that occurs primarily in severely immunocompromised patients with hematological malignancies and in transplant recipients. IA has been increasing globally due to advancements in the medical management of these patients and has recently been recognized as a global public health concern. In 2022, the World Health Organization released their Fungal Priority Pathogen List that designated Aspergillus fumigatus, the most common cause of IA, to be in the Critical Priority group (i.e., the highest perceived public health threat). Aspergillus is also included in the FDA qualified designation list of pathogens that pose a serious and life-threatening risk.
The one-year mortality for patients with IA has been reported to be
The Infectious Diseases Society of America (IDSA) Treatment Guidelines recommend that patients with IA receive treatment with a mold-active azole for a minimum of 6 to 12 weeks, largely dependent on the degree and duration of immunosuppression, site of disease, and evidence of disease. Although the mold-active azoles are generally effective, their use requires a considerable degree of expertise to manage toxicities and drug-drug interactions which often limit duration of treatment.
IA caused by Aspergillus species that are resistant to mold-active azoles has been increasing globally due to the chronic use of azoles and the widespread use of azole fungicides in agriculture. This emerging resistance is particularly concerning because IA due to azole-resistant Aspergillus is a life-threatening disease with a high mortality rate.
Patients with hematological malignancies and transplant recipients often receive antifungal prophylaxis with a mold-active azole to prevent infection during high-risk periods. Recently, cases of breakthrough IA have been reported in patients receiving antifungal prophylaxis. The reason for these apparent failures of prophylaxis may be non-compliance, poor absorption, drug-drug interactions, or infection with a drug-resistant Aspergillus species.
The IDSA Treatment Guidelines recommend an intravenously administered amphotericin B, such as AmBisome, as an alternative for patients with IA who are unable to receive treatment with a mold-active azole. However, IV amphotericin B can cause nephrotoxicity and electrolyte abnormalities which usually requires hospitalization for close monitoring and electrolyte supplementation. Other complications of IV amphotericin B include acute infusion reactions with dyspnea, hypoxia, chest and back pain, IV-site phlebitis, anemia, and hepatotoxicity. As such, treatment with IV amphotericin B for more than a few weeks is generally not safe or practical. There are no oral antifungals available that will enable these patients to complete the recommended 6 to 12 weeks of treatment. Accordingly, there is a critical unmet medical need for effective and well-tolerated oral antifungal agents to treat these patients with IA.
MAT2203 is not yet licensed or approved anywhere globally.
About MAT2203
Matinas BioPharma is developing MAT2203 as a potential oral broad-spectrum treatment for invasive deadly fungal infections. Although amphotericin B is a fungicidal agent, it is currently only available through an intravenous route of administration, which is known to be associated with several significant safety issues such as renal toxicity and anemia due to very high circulating levels of amphotericin B. MAT2203 has the potential to overcome the significant limitations of the currently available amphotericin B products due to its targeted oral delivery, combining comparable fungicidal activity with targeted delivery resulting in a lower risk of toxicity and potentially creating the ideal antifungal agent for the treatment of invasive fungal infections. MAT2203 was successfully evaluated in the completed Phase 2 EnACT study in cryptococcal meningitis, meeting its primary endpoint and achieving robust survival.
