MIAMI BEACH, Fla., Dec. 06, 2022 (GLOBE NEWSWIRE) -- Pasithea Therapeutics Corp. (NASDAQ: KTTA) (“Pasithea” or the “Company”), a biotechnology company focused on the discovery, research and development of innovative treatments for Central Nervous System (CNS) disorders, today announced that Lawrence Steinman, Pasithea’s Chairman and a member of the National Academy of Sciences , will present preclinical data for PAS-003 in a discussion entitled “Targeting alpha5 Integrin in ALS.” The presentation is included in the Novel Targets for Antibody Therapeutics track on December 7th at the Antibody Engineering & Therapeutics Conference held in San Diego. Pasithea’s discovery candidate, PAS-003, has a novel mechanism of action with the potential to improve clinical outcomes in patients with ALS. The target, Alpha 5 Beta 1 integrin, and its potential role in ALS is supported by post-mortem human tissue studies and pre-clinical studies which show a reproducible significant improvement in behavior and survival in the SOD1 mouse model. “We’re pleased to present our data at such a prestigious annual conference that includes a keynote address by this year’s Nobel Laureate for chemistry,” commented Dr. Steinman. About Pasithea Therapeutics Corp. Pasithea Therapeutics is a biotechnology company primarily focused on the discovery, research and development of innovative treatments for central nervous system (CNS) disorders. With an experienced team of experts in the fields of neuroscience and psychopharmacology, Pasithea is developing new molecular entities for the treatment of neurological disorders, including Amyotrophic Lateral Sclerosis (ALS) and Multiple Sclerosis, Neurofibromatosis type 1 and Noonan syndrome. ABOUT PAS-003 PAS-003 is monoclonal antibody targeting alpha5/beta1 integrin for the treatment of Amyotrophic Lateral Sclerosis (ALS) and other neurological diseases. About Amyotrophic Lateral Sclerosis ALS is a progressive neurodegenerative disease that affects nerve cells in the brain and spinal cord, causing loss of muscle control. It most commonly affects people between the ages of 40 and 70, with an average age of 55 at the time of diagnosis. It affects as many as 30,000 patients in the United States, with 5,000 new cases diagnosed each year. The average life expectancy after diagnosis is two to five years, but some patients may live for years or even decades. While 5-10% of cases are hereditary (familial ALS), the large majority of cases (90-95%) are not hereditary (Sporadic ALS). The cause of ALS is not completely understood and multiple complex factors may contribute to the death of motor neurons. Currently there is no known cure or treatment that halts or reverses the progression of ALS, and FDA only approved 2 medications so far for the treatment of this disorder, both shown to modestly slow the progression of ALS.

(Nasdaq: LSTA) (“Lisata” or the “Company”), a clinical-stage pharmaceutical company developing innovative therapies for the treatment of advanced solid tumors and other serious diseases, today announced its financial results for the three and nine months ended September 30, 2022 and provided a business update. "We are excited to report our first quarter as Lisata Therapeutics following the merger of Caladrius Biosciences and Cend Therapeutics,” stated David J. Mazzo, Ph.D., Chief Executive Officer of Lisata. “The team has made tremendous progress over the past few months and now, as Lisata, we are building an enduring pharmaceutical company for the treatment of diseases with significant unmet medical needs. As such, our primary focus is the advancement of our clinical development pipeline of candidates targeting oncology and ischemic disease indications. LSTA1, our lead investigational product candidate from the CendR Platform™, is the subject of multiple planned and ongoing clinical trials being conducted globally in a variety of solid tumor types and in combination with several chemotherapy and immunotherapy anti-cancer regimens. We believe that LSTA1 has the potential to become an integral part of a revised standard-of-care therapy for many difficult to treat cancers. Recent guidance from the U.S. Food and Drug Administration has given us further direction on what would be required for registration. We have discussed this guidance with our development partners and we are planning adjustments to protocols, including the modification and expansion of ongoing studies. Dr. Mazzo continued, “Overall, we’re invigorated by the promise of our platform technologies and pipeline of product and partnering opportunities and look forward to providing updates on our progress in the coming months.” Development Portfolio Update LSTA1 as a treatment for solid tumor cancers in combination with other anti-cancer agents LSTA1, formerly known as CEND-1, is an investigational drug that actuates the CendR active transport mechanism while also having the potential to modify the tumor microenvironment (“TME”) and make is less immunosuppressive. It is targeted to tumor vasculature by its affinity for alpha-v, beta-3 and beta-5 integrins that are selectively expressed in tumor vasculature, but not healthy tissue. LSTA1 is a specific cyclic internalizing RGD (“iRGD”) peptide that, once bound to these integrins, is cleaved by proteases expressed in tumors to release a peptide fragment, called a CendR fragment, which binds to a second receptor, called neuropilin-1, to activate a novel uptake pathway that allows anticancer drugs to more selectively penetrate solid tumors. The ability of LSTA1 and iRGD peptides to modify the TME to enhance delivery and efficacy of co-administered drugs has been demonstrated in models of a range of solid tumors with the results from Lisata, collaborators and research groups around the world having been the subject of over 200 scientific publications. Lisata and its collaborators have also amassed significant non-clinical data demonstrating enhanced delivery of a range of emerging anti-cancer therapies, including immunotherapies and RNA-based therapeutics. Clinically, LSTA1 has demonstrated favorable safety, tolerability, and activity in clinical trials to enhance delivery of standard-of-care chemotherapy for pancreatic cancer. Lisata is exploring the potential of LSTA1 to enable a variety of treatment modalities to treat a range of solid tumors more effectively. Currently, LSTA1 is the subject of Phase 1b/2a and 2b clinical studies being conducted globally in various solid tumors, including metastatic pancreatic ductal adenocarcinoma, in combination with a variety of anti-cancer regimens. The combination of LSTA1 with corresponding standards-of-care in other solid tumor indications is planned for clinical study in the first half of 2023. HONEDRA® (LSTA12, aka CLBS12) for the treatment of critical limb ischemia (“CLI”) HONEDRA® is the Company’s SAKIGAKE-designated product candidate for the treatment of CLI and Buerger’s disease in Japan, which is now in the pre-consultation phase of the registration process with the Pharmaceuticals and Medical Devices Agency (“PMDA”) in Japan. Data from the follow-up of all patients completed in the registration-eligible clinical trial in Japan have been compiled and are being reviewed by the PMDA, after which the PMDA is expected to provide important perspective to be considered in preparation for the formal consultation meetings which precede the Japanese new drug application. If successful in the pre-consultation process, Lisata expects formal clinical consultation to occur by mid-year 2023. Concomitantly, the Company is focusing its efforts to secure a Japanese partner to complete the remaining steps to produce registration in Japan. XOWNA® (LSTA16, aka CLBS16) for the treatment of coronary microvascular dysfunction (“CMD”) XOWNA® is an experimental regenerative therapy for the treatment of CMD. It was the subject of a positive Phase 2a study (the “ESCaPE-CMD trial”) reported in 2020 and is currently being evaluated in a U.S. Phase 2b study (the “FREEDOM Trial”). The FREEDOM Trial was originally designed as a 105-patient double-blind, randomized, placebo-controlled trial to further evaluate the efficacy and safety of intracoronary delivery of autologous CD34+ cells (XOWNA®) in subjects with CMD and without obstructive coronary artery disease and was expected to complete enrollment in approximately 12 months. As previously disclosed, enrollment in the FREEDOM Trial initially proceeded as planned with the first patient treated in January 2021; however, the impact of the COVID-19 pandemic in the U.S., coupled with supply chain issues associated with the catheters used for diagnosis of CMD and/or administration of XOWNA®, as well as with a contrast agent typically used in many catheter laboratories, have made and continue to make enrollment much slower than originally predicted and challenging to accelerate. As a result, the Company announced that enrollment in the FREEDOM Trial had been suspended and that it intended to conduct an interim analysis of the data from not less than the first 20 patients enrolled using the 6-month follow-up data to evaluate the efficacy and safety of XOWNA® in subjects with CMD. Following the analysis of results of the FREEDOM Trial subjects completing 6-month follow-up along with Key Opinion Leaders’ input, the Company’s board of directors determined that execution of a redesigned FREEDOM-like trial would be the appropriate next step, but the cost of such a trial would be prohibitively expensive to undergo alone and without a strategic partner. Accordingly, the Company’s board of directors concluded that XOWNA® development will only be continued if a strategic partner that can contribute the necessary capital for a redesigned trial is identified and secured. LSTA201 (aka CLBS201) for the treatment of diabetic kidney disease (“DKD”) Progressive kidney failure is associated with attrition of the microcirculation of the kidney. Preclinical studies in kidney disease and injury models have demonstrated that protection or replenishment of the microcirculation results in improved kidney function. Based on these observations, the Company initiated a Phase 1b, open-label, proof-of-concept trial evaluating LSTA201, a CD34+ regenerative cell therapy investigational product for intra-renal artery administration in patients with DKD. Patients selected for the study are in the pre-dialysis stage of kidney disease and exhibit rapidly progressing stage 3b disease. The protocol provides for a cohort of six patients overseen by an independent Data Safety Monitoring Board with the objective of determining the tolerance of intra-renal cell therapy injection in DKD patients as well as the ability of LSTA201 to regenerate kidney function. A key read-out of data will occur at the 6-month follow-up visit for all patients. The Company treated the first patient in April 2022 and completed treatment for all six subjects during the third quarter of 2022. Top-line data is anticipated from all subjects by the first quarter of 2023. Third Quarter 2022 Financial Highlights Research and development expenses were approximately $3.4 million for the three months ended September 30, 2022, compared to $4.1 million for the three months ended September 30, 2021, representing a decrease of $0.7 million or 18.1%. This was primarily due to a decrease in expenses associated with our XOWNA® Phase 2b study (the FREEDOM Trial) as a result of the suspension in enrollment which commenced in the second quarter of 2022 and study close out activities in the third quarter of 2022, a decrease in expenses associated with HONEDRA® in Japan related to study close out costs partially offset by the addition of Chemistry, Manufacturing, and Controls (“CMC”) activities for LSTA1, and enrollment activities for Australasian Gastrointestinal Trials Group (“AGITG”) ASCEND study. Research and development in both periods related to: expenses associated with our XOWNA® Phase 2b study (the FREEDOM Trial);expenses associated with our registration-eligible study for HONEDRA® in CLI in Japan as well as corresponding regulatory discussions and support expenses;expenses associated with the preparation of our filing of an Investigational New Drug Application, as well as study execution expenses for the clinical study of LSTA201 for treatment of DKD, a Phase 1b, open-label, proof-of-concept trial which includes six subjects in total;expenses associated with the addition of CMC activities for LSTA1, enrollment activities for the LSTA1 Phase 2b ASCEND study and preparatory activities associated with the design of a planned LSTA1 proof-of-concept basket trial in various solid tumors and in combination with the corresponding standards of care. General and administrative expenses, which focus on general corporate related activities, were $3.9 million for the three months ended September 30, 2022, compared to $2.8 million for the three months ended September 30, 2021, representing an increase of 39%. This increase was primarily due to an increase in equity expense as a result of performance stock unit vesting, a one-time merger option assumption expense and departing board member restricted stock unit vesting in addition to an increase in expenses associated with our annual stockholder meeting and the merger. Net losses were $37.4 million for the three months ended September 30, 2022, compared to $6.9 million for the three months ended September 30, 2021. Balance Sheet Highlights As of September 30, 2022, the Company had cash, cash equivalents and marketable securities of approximately $75.5 million.

Researchers found that particles which are secreted by tumor cells, extracellular vesicles (EVs), displayed a high level of protein integrins alpha-v and beta-1, in patients with locally advanced and metastatic breast cancer. One woman is diagnosed with breast cancer every fourteen seconds somewhere across the globe -- based on data showing that an approximate 2.3 million women worldwide were newly diagnosed with breast cancer in 2020. In Singapore, it is the most common cancer among women, and will likely affect one in thirteen women in their lifespan. Although advances in medicine today allow for treatments for early-stage and non-metastatic breast cancer, advanced stage and metastatic breast cancer is considered incurable with current treatment options, with very poor prognosis. The early detection of breast cancer metastasis is therefore paramount in the treatment of the condition, and a team of researchers discovered a non-invasive biomarker that could aid with earlier diagnosis. Led by Assistant Professor Minh Le from the Institute for Digital Medicine (WisDM) and Department of Pharmacology at the National University of Singapore's Yong Loo Lin School of Medicine (NUS Medicine), and Associate Professor Andrew Grimson from the Department of Molecular Biology and Genetics at Cornell University, the researchers found that particles which are secreted by tumour cells, extracellular vesicles (EVs), displayed a high level of protein integrins αv and β1, in patients with locally advanced and metastatic breast cancer. Asst Prof Le said, "Metastasis is the chief concern for breast cancer patients. The study highlights the potential of integrins αv and β1 as a promising prognostic and therapeutic target for patients with metastatic breast cancer. Our research has opened several doors, and we hope that future work will help develop new ways to assess, monitor and suppress this hallmark of cancer." Published in the Journal of Extracellular Vesicles, the team used an ultra-sensitive protein identification tool to obtain a set of protein expression profiles from the EVs of different metastatic breast cancer cell lines. They discovered that, among many candidate proteins, integrins αv and β1 were consistently overexpressed in EVs of high metastatic background. In addition, the team collaborated with Associate Professor Victor Lee, Senior Consultant, Department of Pathology, National University Hospital, and found a high level of integrin αv in samples from patients with stage III or IV breast cancer. He said, "Through the study, we discovered the potential of integrin αv as a new non-invasive biomarker for the early diagnosis of breast cancer metastasis." Assoc Prof Grimson added, "The study has led to fundamental insights in the underlying mechanisms of breast cancer metastasis. In addition to its clinical relevance, the research contributes to recent advances in the EV field, in that there are functionally distinct subsets of EVs, which can now be more readily identified and studied to understand their functions and potential as therapeutic targets in the tumour environment."
