The Israel Innovation Authority will fund Pluri and BIRAD's collaboration to advance MAIT Cell Therapy, led by Professor Cyrille Cohen, Head of the laboratory of tumor immunology and immunotherapy at Bar-Ilan UniversityMAIT cells hold immense potential for immunotherapy and the treatment of solid tumors compared to conventional T-cells, but their expansion has been a challenge until Pluri announced its proprietary MAIT immunotherapy platform in May 2024Global cancer immunotherapy market is expected to reach $312 billion by 2033 HAIFA, Israel, Oct. 28, 2024 (GLOBE NEWSWIRE) -- Pluri Inc. (Nasdaq:PLUR) (TASE:PLUR) (“Pluri” or the “Company”), a leading biotechnology company that transforms cells into solutions, today announced that the Israel Innovation Authority (“IIA”) will fund Pluri’s collaboration with the Bar-Ilan University Research and Development Company Ltd., (“BIRAD”), the commercial arm of Bar-Ilan University, to support the continued development of Placental Mucosal Associated Invariant T (“MAIT”) cells for solid tumors. MAIT cells are known to have unique advantages compared to conventional T-cells but have previously been difficult to expand and scale for clinical investigation and potential commercialization. MAIT cells are believed to be particularly suitable for the treatment of solid tumors, a significant unmet medical need. Under this collaboration, Prof. Cohen’s novel Siglec-based Chimeric Switch Receptors (“CCR”) will be integrated into Pluri’s CAR-MAIT cell therapy platform to significantly enhance CAR-MAIT’s efficacy and tumor specificity. By leveraging the complementary strengths of both parties, Pluri’s expertise in the MAIT cell platform and the experience of Prof. Cohen’s group in developing clinically relevant and optimized T-cell genetic modification vectors, this collaboration is poised to advance innovative allogeneic cell therapies targeting solid tumors. The IIA will fund Pluri and BIRAD’s collaboration over the next year, with an option of funding an additional year. The goal of this collaboration is to effectively integrate both innovative technologies and advance to preclinical studies. As announced in May 2024, Pluri leveraged two decades of cell expansion expertise and its proprietary technology to create a novel, patented method for expansion of immune cells. Pluri’s MAIT cells are isolated from healthy human placentas, a source rich in highly potent immune cells. Notable characteristics of Pluri’s placental MAIT cells include their potency as effector cells, their potential ability to target tumors through multiple mechanisms, and their expression of high levels of various chemokine receptors, which facilitate their migration to tumor sites. MAIT cells hold unique properties that minimize their likelihood of inducing Graft versus Host Disease (GvHD), a serious complication associated with other potential allogeneic products. “I’m thrilled to collaborate with Pluri on this innovative project to be supported by the Israel Innovation Authority,” said Prof. Cyrille Cohen. “By combining our patent pending Siglec-based receptor technology and our expertise in designing potent CAR vectors for clinical applications, together with Pluri’s advanced capabilities in cultivating MAIT cells, we aim to harness the unique biological properties of these cells. While immunotherapy has shown great success in treating blood cancers, an equivalent success has yet to be duplicated in solid tumor malignancies. This collaboration offers the potential to overcome that challenge by creating powerful, off-the-shelf CAR T-cell therapies that specifically target solid tumors.” “For over two decades, our team has been at the forefront of cell therapy research. We are excited to partner with BIRAD to combine our MAIT platform with Prof. Cohen's innovative CCR technology,” said Yaky Yanay, Chief Executive Officer and President of Pluri. “This promising collaboration, recognized by the Israel Innovation Authority for its innovative potential, will help us create more effective immunotherapies for patients with solid cancer. We appreciate the IIA's support in making this possible.” Total Addressable MarketThe global cancer immunotherapy market was valued at $111 billion in 2023 and is expected to surpass $312 billion by 2033, poised to grow at a compound annual growth rate of 10.9%.

FLORHAM PARK, N.J., Oct. 27, 2024 (GLOBE NEWSWIRE) -- Phathom Pharmaceuticals, Inc. (Nasdaq: PHAT), a biopharmaceutical company focused on developing and commercializing novel treatments for gastrointestinal (GI) diseases, today announced that the company will present data from multiple investigational studies for its first-in-class treatment VOQUEZNA® (vonoprazan) tablets at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting, being held October 25-30 in Philadelphia, PA. VOQUEZNA is approved for the relief of heartburn associated with Non-Erosive Gastroesophageal Reflux Disease (Non-Erosive GERD), for the treatment of all severities of Erosive Esophagitis, commonly referred to as Erosive GERD, and relief of related heartburn, and in combination with antibiotics for the eradication of Helicobacter pylori (H. pylori) infection.1 VOQUEZNA is the first and only U.S. Food and Drug Administration (FDA)-approved potassium-competitive acid blocker (PCAB).2 Evaluating On-Demand VOQUEZNA Treatment from the PHALCON-NERD-201 Trial3In an oral presentation being presented Monday, October 28 at ACG, Ronnie Fass, M.D., director of the Division of Gastroenterology and Hepatology and medical director of the Digestive Health Center at MetroHealth in Cleveland, Ohio, and lead investigator of the PHALCON-NERD-201 trial, will provide results from a post-hoc analysis of the Phase 2 study. This research, recognized with the ACG Outstanding Research Award in the ‘Esophagus’ category, evaluated the efficacy of As Needed (On-Demand) dosing of VOQUEZNA, compared to placebo, for relief of episodic heartburn in participants with Non-Erosive GERD following a 4-week VOQUEZNA daily dosing “run-in” period. As previously reported, the primary analysis of the study demonstrated that all three VOQUEZNA doses tested (10 mg, 20 mg and 40 mg) had higher percentages of heartburn completely relieved within three hours of dosing and sustained for 24 hours, with significant differences reported as early as one hour. Use of As Needed dosing in this population is investigational as VOQUEZNA has been neither evaluated nor approved by the FDA as an As Needed treatment for Non-Erosive GERD. To understand the practical application of As Needed dosing for VOQUEZNA, the new analysis examined daily heartburn symptom burden at baseline, during daily VOQUEZNA treatment, and upon switching to As Needed treatment after achieving symptom control during the run-in period. It also further evaluated the rate of symptom improvement upon treating new onset heartburn episodes during the As Needed dosing period.3 “As a healthcare provider, the concept of a novel As Needed dosing option for Non-Erosive GERD is highly compelling. I am pleased that ACG has recognized this data as a recipient of the ACG Outstanding Research Award, further reinforcing its importance to the GI community,” said Ronnie Fass, M.D. “The low frequency of heartburn after discontinuing daily VOQUEZNA treatment, coupled with the rapid onset of improvement following As Needed dosing, suggests that transitioning from daily dosing to As Needed treatment is a viable option for patients who previously respond well to daily therapy of VOQUEZNA. These promising results warrant further investigation in a larger and extended As Needed study period.” The double-blind, placebo-controlled PHALCON-NERD Phase 2 study randomized 207 patients who were eligible for On-Demand (“As Needed”) treatment following a 4-week daily dosing run-in period in which patients received VOQUEZNA 20 mg once-daily. Patients without heartburn in the last seven days of the run-in period were evenly randomized to receive 10 mg, 20 mg or 40 mg of VOQUEZNA, or placebo, for six weeks. Results of the study were published in Alimentary Pharmacology & Therapeutics in September 2023.4 Results:3 Patients eligible for the On-Demand period (n=207) were highly symptomatic with a reported mean of 16.1% [95% CI: (13.5%, 18.7%)] heartburn-free days during screening. Heartburn-free days increased during the run-in period to a mean of 82.9% [95% CI: (80.4%, 85.4%)] and remained well above pre-treatment levels (means 71% to 75%) throughout the six-week On-Demand period.The difference in the improvement of treated heartburn episodes between the active and placebo groups became evident within the first hour of dosing (10 mg [75.5%, p<0.0001], 20 mg [69.1%, p = 0.0010], 40 mg [75.5%, p<0.0001], placebo [57.0%]).Over 90% of heartburn episodes treated with VOQUEZNA improved within two hours. Non-Erosive GERD is the largest category of GERD and is characterized by reflux-related symptoms in the absence of esophageal mucosal erosions. An estimated 45 million U.S. adults are living with Non-Erosive GERD, and approximately 15 million are treated with a prescription medicine annually. Despite longstanding treatment options, many patients continue to suffer from heartburn symptoms. As Needed dosing is a unique and differentiated dosing regimen for which proton pump inhibitors (PPIs), a mainstay of GERD treatment, are not approved in the U.S.5 In July 2024, VOQUEZNA was approved by the FDA as a daily dosing treatment for the relief of heartburn associated with Non-Erosive GERD in adults.1 Nocturnal GERD Symptoms in Non-Erosive GERD6 In a poster presentation on Monday, October 28 at ACG, which has received ACG’s Presidential Poster Award, Dr. Catiele Antunes, M.D., Yale New Haven Hospital, will present data looking at the common, yet infrequently evaluated, nocturnal symptoms among patients with Non-Erosive GERD. The study included an exploratory analysis of a validated patient-reported outcomes scale, the Nocturnal Gastro-esophageal reflux disease Symptom Severity and Impact Questionnaire (N-GSSIQ), to determine the severity, morning impact, and concern about nocturnal GERD. “We are very pleased to continue to add to the body of clinical research evaluating the potential benefits of VOQUEZNA for GERD patients,” said Eckhard Leifke, M.D., Chief Medical Officer at Phathom. “In our study, patients who experienced nocturnal GERD symptoms prior to VOQUEZNA treatment found effective and meaningful relief with daily dosing, reinforcing its potent and durable acid suppression profile in helping to address both daytime and nighttime heartburn. While these findings are exploratory, they show promise for the many individuals suffering from nocturnal GERD symptoms.” Results:6 Among 772 subjects, the mean percentage of heartburn-free nights during the screening period was 29.6%, 25.8% and 31.1%, for patients randomized to placebo, VOQUEZNA 10 mg and 20 mg, respectively.After 4 weeks, the least-square (LS) mean percentage of heartburn-free nights was significantly better with 59.9% for VOQUEZNA 10 mg (LS mean difference=16.5%, p<0.0001 vs. placebo), and 56.4% for VOQUEZNA 20 mg (LS mean difference=13.1%, p<0.0001 vs. placebo), compared to 43.3% for placebo. The median percentage of heartburn-free nights was 70.4% for VOQUEZNA 10 mg and 71.0% for VOQUEZNA 20 mg, compared to 45.5% for placebo.N-GSSIQ scores showed significant improvement with VOQUEZNA compared to placebo in total score (LS mean difference vs. placebo of -2.9 and -1.8 for VOQUEZNA 10 mg and 20 mg, respectively; p<0.005 for both comparisons), nocturnal symptom severity (LS mean difference vs. placebo of -5.4 and -3.5 for VOQUEZNA 10 mg and 20 mg; p<0.001 for both comparisons), and concern about nocturnal GERD (LS mean difference vs. placebo of -2.0 for both VOQUEZNA 10 mg and 20 mg; p<0.0001). In addition to these data presentations, Phathom will sponsor a product theater highlighting VOQUEZNA as an approved treatment for GERD and will also have a presence on the exhibit floor at booth #757 throughout the conference. Following the conclusion of ACG 2024, the abstracts will be posted to the publications and scientific section of the Phathom company website. VOQUEZNA is marketed exclusively by Phathom Pharmaceuticals, Inc. and is currently available via prescription. Please visit voqueznapro.com to learn more about VOQUEZNA. About Non-Erosive Gastroesophageal Reflux DiseaseNon-Erosive GERD is the largest category of GERD and is characterized by reflux-related symptoms in the absence of esophageal mucosal erosions. There are over 65 million U.S. patients living with GERD, and it is estimated that approximately 70% of this population have Non-Erosive GERD. Symptoms of Non-Erosive GERD may impact overall quality of life and can include episodic heartburn, especially at night, regurgitation, problems swallowing, and chest pain.7,8 About VOQUEZNA®VOQUEZNA® (vonoprazan) tablets contain vonoprazan, an oral small molecule potassium-competitive acid blocker (PCAB). PCABs are a novel class of medicines that block acid secretion in the stomach. VOQUEZNA is approved in the U.S. for the treatment of adults with Erosive Esophagitis, also known as Erosive GERD, the relief of heartburn associated with Erosive GERD, the relief of heartburn associated with Non-Erosive GERD, and for the treatment of H. pylori infection in combination with either amoxicillin or amoxicillin and clarithromycin. Phathom in-licensed the U.S. rights to vonoprazan from Takeda, which markets the product in Japan and numerous other countries in Asia and Latin America.

IMPORTANT SAFETY INFORMATION CONTRAINDICATIONS VOQUEZNA is contraindicated in patients with a known hypersensitivity to vonoprazan or any component of VOQUEZNA, or in patients receiving rilpivirine-containing products. For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with VOQUEZNA, refer to the Contraindications section of the corresponding prescribing information. WARNINGS AND PRECAUTIONS Presence of Gastric Malignancy: In adults, symptomatic response to therapy with VOQUEZNA does not preclude the presence of gastric malignancy. Consider additional follow-up and diagnostic testing in patients who have a suboptimal response or an early symptomatic relapse after completing treatment with VOQUEZNA. In older patients, also consider endoscopy. Acute Tubulointerstitial Nephritis: Acute tubulointerstitial nephritis (TIN) has been reported with VOQUEZNA. If suspected, discontinue VOQUEZNA and evaluate patients with suspected acute TIN. Clostridioides difficile-Associated Diarrhea: Published observational studies suggest that proton pump inhibitors (PPIs) may be associated with an increased risk of Clostridioides difficile-associated diarrhea (CDAD), especially in hospitalized patients. VOQUEZNA may also increase the risk of CDAD. Consider CDAD in patients with diarrhea that does not improve. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. CDAD has been reported with use of nearly all antibacterial agents. For more information specific to antibacterial agents (clarithromycin and amoxicillin) indicated for use in combination with VOQUEZNA, refer to Warnings and Precautions section of the corresponding prescribing information. Bone Fracture: Several published observational studies suggest that PPI therapy may be associated with an increased risk for osteoporosis-related fractures of the hip, wrist, or spine, especially in patients receiving high dose (multiple daily doses) and long-term therapy (a year or longer). Bone fracture, including osteoporosis-related fracture, has also been reported with vonoprazan. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. Patients at risk for osteoporosis-related fractures should be managed according to the established treatment guidelines. Severe Cutaneous Adverse Reactions (SCAR): Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) have been reported with VOQUEZNA. Discontinue VOQUEZNA at the first signs or symptoms of SCAR or other signs of hypersensitivity and consider further evaluation. Vitamin B12 (Cobalamin) Deficiency: Long-term use of acid-suppressing drugs can lead to malabsorption of Vitamin B12 caused by hypo- or achlorhydria. Vitamin B12 deficiency has been reported postmarketing with vonoprazan. If clinical symptoms consistent with vitamin B12 deficiency are observed in patients treated with VOQUEZNA, consider further workup. Hypomagnesemia and Mineral Metabolism: Hypomagnesemia has been reported postmarketing with vonoprazan. Hypomagnesemia may lead to hypocalcemia and/or hypokalemia and may exacerbate underlying hypocalcemia in at-risk patients. Consider monitoring magnesium levels prior to initiation of VOQUEZNA and periodically in patients expected to be on prolonged treatment, in patients taking drugs that may have increased toxicity in the presence of hypomagnesemia or drugs that may cause hypomagnesemia. Treatment of hypomagnesemia may require magnesium replacement and discontinuation of VOQUEZNA. Consider monitoring magnesium and calcium levels prior to initiation of VOQUEZNA and periodically while on treatment in patients with a preexisting risk of hypocalcemia. Supplement with magnesium and/or calcium, as necessary. If hypocalcemia is refractory to treatment, consider discontinuing VOQUEZNA. Interactions with Diagnostic Investigations for Neuroendocrine Tumors: Serum chromogranin A (CgA) levels increase secondary to drug-induced decreases in gastric acidity. The increased CgA level may cause false positive results in diagnostic investigations for neuroendocrine tumors. Temporarily discontinue VOQUEZNA treatment at least 4 weeks before assessing CgA levels and consider repeating the test if initial CgA levels are high. Fundic Gland Polyps: Use of VOQUEZNA is associated with a risk of fundic gland polyps that increases with long-term use, especially beyond one year. Fundic gland polyps have been reported with vonoprazan in clinical trials and during postmarketing use with PPIs. Most patients who developed fundic gland polyps were asymptomatic and fundic gland polyps were identified incidentally on endoscopy. Use the shortest duration of VOQUEZNA appropriate to the condition being treated. ADVERSE REACTIONS: Healing of Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include gastritis (3%), diarrhea (2%), abdominal distention (2%), abdominal pain (2%), and nausea (2%). Maintenance of Healed Erosive GERD: The most common adverse reactions (≥3% of patients in the VOQUEZNA arm) include gastritis (6%), abdominal pain (4%), dyspepsia (4%), hypertension (3%), and urinary tract infection (3%). Relief of Heartburn Associated with Non-Erosive GERD: The most common adverse reactions (≥2% of patients in the VOQUEZNA arm) include abdominal pain (2%), constipation (2%), diarrhea (2%), nausea (2%), and urinary tract infection (2%). Treatment of H. Pylori Infection (VOQUEZNA and Amoxicillin): The most common adverse reactions (≥2% in any treatment arm) include diarrhea (5%), abdominal pain (3%), vulvovaginal candidiasis (2%), nasopharyngitis (2%), dysgeusia (1%), headache (1%), and hypertension (1%). Treatment of H. Pylori Infection (VOQUEZNA, Amoxicillin and Clarithromycin): The most common adverse reactions (≥2% in any treatment arm) include dysgeusia (5%), diarrhea (4%), vulvovaginal candidiasis (3%), headache (3%), abdominal pain (2%), hypertension (2%), and nasopharyngitis (<1%). For more information on adverse reactions and laboratory changes with amoxicillin or clarithromycin, refer to Adverse Reactions section of the corresponding prescribing information. DRUG INTERACTIONS VOQUEZNA has the potential for clinically important drug interactions, including interactions with drugs dependent on gastric pH for absorption, drugs that are substrates for certain CYP enzymes, and some diagnostic tests. Avoid concomitant use of VOQUEZNA with atazanavir or nelfinavir. See full Prescribing Information for more details about important drug interactions. Consult the labeling of concomitantly used drugs to obtain further information about interactions with vonoprazan. For information about drug interactions, contraindications, and warnings and precautions of antibacterial agents (amoxicillin or clarithromycin) indicated in combination with VOQUEZNA, refer to their corresponding prescribing information. USE IN SPECIFIC POPULATIONS Lactation: Breastfeeding is not recommended during treatment. Because of the potential risk of adverse liver effects shown in animal studies with vonoprazan, advise patients not to breastfeed during treatment with VOQUEZNA. Renal Impairment: For the healing of Erosive GERD, dosage reduction is recommended in patients with severe renal impairment (eGFR < 30 mL/min). Use of VOQUEZNA is not recommended for the treatment of H. pylori infection in patients with severe renal impairment.

Frazier Life Sciences has added more than $630 million to its evergreen public fund, the firm said Wednesday. The long-only fund, which is based in Palo Alto, CA, has been marketed to investors as a “hybrid structure to navigate volatility and liquidity in SMID-cap biotech,” according to materials posted by the New Mexico State Investment Council, which is committing up to $50 million to the public fund. “We are seeking to strategically take advantage of market volatility,” the firm said in June in its investor presentation. It now has $1.7 billion in total commitments after debuting with $830 million in 2021 and raising $243 million a year later. The biotech landscape is far different than when Frazier unwrapped its public fund in the fall of 2021. In September of that year, the number of life sciences companies with a negative enterprise value was 21. As of Sept. 20 of this year, that tally stood at 133, according to a recent Stifel report . “The number of early-stage companies going public has just exploded over the course of the last five-plus years,” general partner Jamie Brush told Endpoints News in 2021. “So the opportunity set for early-stage companies where Frazier wants to be investing has really increased on the public side.” The biotech IPO market cratered soon after that unveiling. Since then, initial public offerings have been few and far between, though there’s been a string of debuts this fall and more interest-rate cuts could be a positive signal for the market going forward. Follow-on offerings, meanwhile, have had a “ very strong year ,” according to Stifel. Frazier’s strategy Frazier has five main strategies for the fund. The first is “fallen angels,” which Frazier has described as companies that have “fallen out of favor but have promising assets,” like BridgeBio and Immunovant. Bain Capital Life Sciences, which just raised a $3 billion fourth fund, employs a similar strategy . Another bucket is “proprietary information,” in which Frazier gets data that are not publicly available, as it has done in the case of Rocket Pharmaceuticals and Mirum Pharmaceuticals. The third is “structured terms” or “creative” deals. The firm also invests in companies that are newly public like CG Oncology, which had the largest biotech IPO of the year at $380 million in January . And the final strategy is “off-the-beaten path,” or companies that are “lesser known” such as Egetis Therapeutics and Chinook Therapeutics. Novartis bought Chinook in a deal worth up to $3.5 billion last year. Frazier has said its public fund portfolio companies have secured a dozen FDA approvals, including Acadia’s Daybue, bluebird’s three gene therapies, Iovance’s Amtagvi and Phathom’s Voquezna. Some companies have been acquired, including Iveric Bio, which sold to Astellas for $5.9 billion ; Reata’s $7.3 billion exit to Biogen; Alpine Immune Sciences’ $4.9 billion sale to Vertex; and Sierra Oncology’s $1.9 billion exit to GSK. On the venture side, Frazier last disclosed a $987 million life sciences fund in March 2022.
