iStock, tomozina Pfizer was studying PF-07820435, an orally available agonist of the STING protein, for solid tumors. Pfizer has terminated a Phase I trial of its investigational STING therapy in advanced solid tumors, according to an update to the study’s clinicaltrials.gov page on Thursday. The move to discontinue the trial of PF-07820435 was based on “strategic business reasons,” according to the webpage. “The decision was not based on any safety and/or efficacy concerns.” BioSpace has reached out to Pfizer to confirm the discontinuation and will update this space accordingly. The Phase I trial was testing PF-07820435, with or without the PD-1 inhibitor sasanlimab, in nine patients with confirmed diagnoses of solid tumors. The main objective of the study was to establish the safety of PF-07820435 and detect early signals of efficacy, as well as determine the drug’s recommended dose for further studies. The study was initiated in February last year. STING, which stands for “stimulator interferon genes,” is a protein that plays a central role in a patient’s anti-cancer immune response by activating type I interferons and other inflammatory players. An orally available drug, PF-07820435 belongs to a class of drugs called STING agonists, which work by triggering the STING pathway and promoting immune activity against cancer cells. As of this writing, PF-07820435 remains on the pharma’s pipeline page . If Pfizer does eventually decide to completely drop PF-07820435, it will be the latest casualty in the pharma’s push to trim its pipeline and refine its business strategy. In December 2024, Pfizer turned its back on Sangamo Therapeutics and its gene therapy candidate giroctocogene fitelparvovec, which the companies were previously developing for hemophilia A. Phase III data released in July 2024 showed that 84% of patients treated with giroctocogene fitelparvovec maintained factor VIII activity above 5%, and majority achieved factor VIII levels greater than 15% of normal. Pfizer and Sangamo were supposed to Biologics License Application for giroctocogene fitelparvovec this year. The termination of the companies’ partnership will take effect on April 21, after which the pharma will transition the hemophilia A program back to Sangamo. Last month, Pfizer announced it was pulling its hemophilia B gene therapy Beqvez from markets worldwide—a decision the company pinned on “the limited interest patients and their doctors have demonstrated in hemophilia gene therapies.” Pfizer, in September 2024, likewise withdrew Oxbryta, an oral hemoglobin S polymerization inhibitor that won the FDA’s approval in 2019 for sickle cell disease. The drug has since been linked to a higher occurrence of complications and death.

TAGRISSO has become a standard treatment due to its strong efficacy in both first-line and adjuvant settings. The growing prevalence of EGFR mutations, a rise in lung cancer diagnoses, and broader approvals for early-stage treatment all contribute to its promising growth potential. LAS VEGAS , March 11, 2025 /PRNewswire/ -- DelveInsight's " TAGRISSO Market Size, Forecast, and Market Insight Report" highlights the details around TAGRISSO, a kinase inhibitor of the EGFR, which binds irreversibly to certain mutant forms of EGFR (T790M, L858R, and exon 19 deletions) at approximately nine-fold lower concentrations than wild-type. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of TAGRISSO. The report also highlights the historical and forecasted sales from 2020 to 2034 segmented into 7MM [the United States, the EU4 (Germany, France, Italy, and Spain), the United Kingdom, and Japan]. AstraZeneca's TAGRISSO (osimertinib) Overview TAGRISSO is a prescription medication for adults with non-small cell lung cancer (NSCLC) that carries specific EGFR gene mutations. It is used to help prevent cancer recurrence after surgical tumor removal, as a first-line treatment for metastatic NSCLC, or for patients whose cancer has spread and no longer responds to prior EGFR TKI therapy. As a kinase inhibitor, TAGRISSO irreversibly targets specific mutant forms of EGFR (T790M, L858R, and exon 19 deletions) with significantly higher selectivity than the wild-type EGFR. After oral administration, two active metabolites (AZ7550 and AZ5104) circulate at around 10% of the parent drug and exhibit similar inhibitory effects as osimertinib. In vitro studies also show that osimertinib inhibits HER2, HER3, HER4, ACK1, and BLK at clinically relevant levels. The recommended TAGRISSO dosage is 80 mg once daily, taken with or without food, and continued until disease progression or unacceptable toxicity occurs. Learn more about TAGRISSO projected market size for EGFR mNSCLC @ TAGRISSO Market Potential EGFR is a protein that plays a crucial role in cell growth. When mutations occur in the EGFR gene, they can lead to excessive cell growth, potentially causing cancer. These mutations can take various forms, including deletions, insertions, and point mutations. Among the most common EGFR mutations detected in test results are the EGFR exon 19 deletion and the EGFR L858R point mutation. In non-small cell lung cancer, targeted therapies primarily focus on EGFR-sensitizing mutations and EGFR exon 20 insertions. The most frequently observed EGFR mutations include exon 19 deletions and exon 21 L858R mutations. To address these, the FDA has approved several tyrosine kinase inhibitors (TKIs). In 2023, the EGFR-mutated NSCLC market across the 7MM was valued at approximately USD 4 billion. The NSCLC treatment landscape is becoming increasingly biomarker-driven, with EGFR emerging as one of the most lucrative targets. TAGRISSO remains the leading therapy in this segment, maintaining a strong market presence. However, resistance to EGFR TKIs, particularly after TAGRISSO treatment, is a growing challenge. Developing treatments for patients who experience resistance remains one of the most pressing unmet needs in this space.

Discover how TAGRISSO is shaping the EGFR NSCLC treatment landscape @ TAGRISSO NSCLC TAGRISSO Market Dynamics TAGRISSO, developed by AstraZeneca, is a third-generation EGFR TKI that has become a key player in the treatment of NSCLC with EGFR mutations. Since its approval, TAGRISSO has gained significant traction due to its efficacy in treating both first-line and post-resistance settings, particularly in patients with the T790M resistance mutation. The drug's ability to penetrate the blood-brain barrier and show strong efficacy against brain metastases has further strengthened its market positioning, leading to widespread adoption among oncologists. A major driver of TAGRISSO's market dynamics is its dominance as the preferred first-line treatment for EGFR-mutated NSCLC. This shift from earlier-generation TKIs has been supported by clinical data demonstrating superior progression-free survival (PFS) and overall survival (OS) benefits. The expansion of TAGRISSO's indications, including its approval in the adjuvant setting for early-stage EGFR-mutated NSCLC, has further broadened its market reach. Additionally, AstraZeneca has aggressively pursued global regulatory approvals, ensuring market access across multiple geographies, particularly in high-prevalence regions such as East Asia, where EGFR mutations are more common. However, TAGRISSO faces growing challenges, including the emergence of resistance mechanisms such as MET amplification and C797S mutations, which limit long-term efficacy. To counteract this, AstraZeneca is exploring combination strategies with MET inhibitors and other targeted therapies. Furthermore, increasing competition from next-generation EGFR TKIs, such as those under development by companies like Takeda and Johnson & Johnson, poses a potential threat. Pricing and reimbursement pressures, particularly in cost-sensitive markets, also impact its commercial strategy, necessitating a balance between pricing optimization and maintaining accessibility. Despite these challenges, TAGRISSO remains a blockbuster drug with robust revenue growth, driven by strong clinical performance and strategic lifecycle management. Ongoing clinical trials evaluating its use in earlier disease stages and in combination therapies could further extend its market leadership. With its strong foothold in the EGFR-mutated NSCLC landscape, TAGRISSO is expected to remain a key driver of AstraZeneca's oncology portfolio in the foreseeable future.
