US agency nixes Seagen patent, handing Daiichi Sankyo a win in long-running Enhertu entanglement

After years of patent litigation between cancer drug developers Daiichi Sankyo and Seagen, the U.S. Patent and Trademark Office (U.S. PTO) has handed Daiichi the latest win in the saga. For years, the companies have clashed over Seagen’s so-called “‘039 patent,” which covers certain peptides conjugated to an antibody through various linkers. After a 2008 antibody-drug conjugate (ADC) partnership between the drugmakers ended in 2015, Daiichi Sankyo entered into a lucrative agreement with AstraZeneca to work on what became the cancer blockbuster Enhertu. Seagen staked a claim on the AZ contract in a 2020 lawsuit, arguing that the technology used for the med was created under its previous Daiichi ADC partnership. In 2022, a Texas jury found that Daiichi Sankyo stepped on Seagen’s patent willfully, awarding the latter company $41.8 million in royalties. The now Pfizer-owned company took its case a step further by asking for royalties from future U.S. ...

Blood Test to Track Gene Expression in the Brain Could Help Prevent Neurological Diseases

Encased within a complex network of specialized blood vessels, the brain remains the body’s most protected organ. This intricate structure, while protective against external threats, poses significant challenges for researchers seeking to understand gene expression dynamics and their link to diseases. Addressing this challenge, scientists have now introduced a noninvasive method to track gene expression in the brain, potentially transforming research in brain development, cognitive function, and neurological disorders. The team of scientists at Rice University (Houston, TX, USA) has developed a groundbreaking class of molecules named released markers of activity (RMAs). These RMAs offer a noninvasive solution to measure gene expression in the brain via a simple blood test. Traditionally, assessing gene expression in the brain has been limited to post-mortem analysis or less sensitive and specific modern neuroimaging techniques. The RMA platform, however, introduces a synthetic gene expression reporter into the brain, which synthesizes a protein capable of ...

Four-Biomarker Panel Could Enable Early Ovarian Cancer Detection

Ovarian cancer remains a significant cause of mortality globally. While advancements in cytoreductive surgery and chemotherapy have improved survival for those with epithelial ovarian cancer, prognosis heavily depends on the stage at diagnosis. Early detection, particularly at stage I, offers a five-year survival rate exceeding 90%. However, this rate drops to around 70% for stage II, where cancer is confined to the pelvis, and declines further for later stages, plummeting to a mere 20% at stage IV. Computational models suggest that detecting ovarian cancer in stages I or II could increase the cure rate by 10-30%. Currently, Cancer Antigen 125 (CA125), a protein found in various cells, including those of ovarian cancer, is the only tumor marker recommended for clinical use in diagnosing and managing ovarian cancer. Now, a new study has shown that a panel of four biomarkers is more sensitive than CA125 alone for early ovarian cancer detection, ...

Allakos Skin Drug Fails 2 Mid-Stage Tests, Sparks Restructuring to Cut 50% of Staff

Allakos’s lirentelimab did not beat a placebo in separate Phase 2 tests in atopic dermatitis and spontaneous chronic urticaria. A restructuring now turns the biotech’s focus to an early-stage drug candidate also designed to treat inflammation. By FRANK VINLUAN The lead therapeutic candidate of Allakos has failed in two mid-stage clinical trials for inflammatory skin disorders, leading the biotech to halt work on the drug. Allakos is shifting its focus to an earlier-stage program in its pipeline but will do so with fewer staff. A corporate shakeup is shaving about half of the company’s workforce. San Carlos, California-based Allakos aims to treat allergic, inflammatory, and proliferative diseases with antibodies that target receptors on cells that create immune responses in the body. By activating inhibitory receptors, these drugs are intended to stop inflammation. Its most advanced drug candidate was lirentelimab, which was designed to target an inhibitory receptor on mast cells ...

Gilead calls off Oceanside manufacturing expansion, uproots biologics development team

Gilead Sciences is halting the expansion of its biologics site in Oceanside, California, and is moving the existing team’s responsibilities to its Foster City campus in the same state, a spokesperson confirmed. The move is based on Gilead’s desire to bring members of the biologics development and manufacturing team closer to the company’s R&D unit, which is based in the Bay Area in Foster City, the spokesperson said. “Over the next few years, the majority of our Gilead Biologics teams in our Pharmaceutical Development & Manufacturing organization, most of whom are currently in Oceanside, CA, will transition to Foster City,” the spokesperson said. The move will begin this year and conclude by 2027 “at the latest,” according to Gilead, with business operations continuing “as usual” for the time being. Oceanside and Foster City are about an 8-hour drive apart. The company did not specify how many employees, if any, would ...

Genetic Medicines Biotech Dyne Pulls In $345M for Clinical Tests of Muscle Drugs

Dyne Therapeutics recently reported encouraging Phase 1/2 clinical data in myotonic dystrophy type 1 and Duchenne muscular dystrophy. At the J.P. Morgan Healthcare Conference, CEO Joshua Brumm said Dyne’s existing cash combined with the new capital is expected to last through 2025—well beyond the next key milestones for both therapeutic candidates. By FRANK VINLUAN Dyne Therapeutics started the new year with proof-of-concept clinical data for experimental genetic medicines addressing two rare muscle diseases—one of which has no FDA-approved treatments. Now the biotech has $345 million as it looks toward key tests for both therapies. Ahead of the Martin Luther King Jr. holiday weekend, Dyne closed a stock offering of 19.7 million shares priced at $17.50 each. In the prospectus, Dyne said the net proceeds of the stock offering will be combined with its existing capital to fund ongoing clinical development of the two clinical-stage programs, DYNE-101 and DYNE-251.

Pfizer’s eye for China ADC deals; Astellas’ gastric cancer rejection

Pfizer is still hungry for ADC opportunities, including in the Far East. Astellas’ impressive phase 3 data for its gastric cancer candidate couldn’t garner an approval because of manufacturing issues. Takeda’s 2022 TYK2 buy from Nimbus was highly competitive, an exec said. And more. 1. JPM24: Even after Seagen buyout, Pfizer oncology chief still eyes ADC deals As Pfizer continues its prowl for antibody-drug conjugate (ADCs) deals, the company is keeping an eye on opportunities around the globe. In an interview, Pfizer’s new oncology chief Chris Boshoff, Ph.D., said the company is looking for opportunities in China, which he said “is important in this whole area, especially ADC development.” The company is “not currently looking for big acquisitions,” Boshoff added. 2. Astellas’ gastric cancer candidate rejected by FDA because of manufacturing issues After running two phase 3 trials, Astellas’ near-term approval ambitions for its zolbetuximab have been dashed because of ...

Manufacturing Issues Block Astellas From a First-in-Class Cancer Drug Approval

Astellas Pharma’s zolbetuximab was on track to become the first gastric cancer drug that targets claudin 18.1, a protein found on cancerous stomach cells. Others with clinical-stage programs addressing this this target include AstraZeneca and Bristol Myers Squibb. By FRANK VINLUAN Astellas Pharma’s path to winning the first drug approval for a particular promising gastrointestinal cancer target has hit a detour. The FDA turned down the drugmaker’s application, citing manufacturing issues for the therapy, zolbetuximab. Astellas announced the FDA action earlier this week. The company did not go into detail about the problems spotted by the regulator, but described them as “unresolved deficiencies following its pre-license inspection of a third-party manufacturing facility for zolbetuximab.” Astellas added that the agency did not raise any concerns about the safety or efficacy of the drug, nor is it asking for additional clinical data. Zolbetuximab was developed as a treatment for patients with locally ...

Pfizer CEO promises ‘year of execution’ after recent struggles, Seagen buyout

Pfizer knows it had a bad year in 2023. Speaking to reporters at the 2024 J.P. Morgan Healthcare Conference on Monday, the company’s CEO, Albert Bourla, spoke bluntly about the hits the company took, and he acknowledged the underperformance of certain key launches. But 2024 represents a fresh opportunity for the pharma giant, Bourla said. “In essence, you should expect 2024—after all the changes in the setup that we did in year ’23—to be a year of execution,” he told the JPM audience. Pfizer will attempt to execute, in part, by leveraging its recent $43 billion buyout of antibody-drug conjugate specialist Seagen, Bourla explained. Further, the company hopes to advance its presence in respiratory syncytial virus (RSV), where Pfizer recently launched its vaccine Abrysvo. Still, Bourla was frank about the challenges Pfizer faced in 2023. “The year for us, we missed our internal projections. And also we missed the expectations ...
