As biomarker testing and the demand for tumor-agnostic therapies rise, ROZLYTREK can potentially target a specialized yet valuable market segment. While competition from other TRK inhibitors, such as larotrectinib (VITRAKVI), may influence growth, its ability to penetrate the CNS provides a distinct advantage. LAS VEGAS, March 12, 2025 /PRNewswire/ -- DelveInsight's " ROZLYTREK Market Size, Forecast, and Market Insight Report" highlights the details around ROZLYTREK, an inhibitor of the tropomyosin receptor tyrosine kinases (TRK) TRKA, TRKB, and TRKC (encoded by the neurotrophic tyrosine receptor kinase [NTRK] genes NTRK1, NTRK2, and NTRK3, respectively), proto-oncogene tyrosine-protein kinase ROS1, and ALK with IC50 values of 0.1 to 2 nM. The report provides product descriptions, patent details, and competitor products (marketed and emerging therapies) of ROZLYTREK. 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]. Roche's ROZLYTREK (entrectinib) Overview ROZLYTREK is a tumor-agnostic therapy that introduces a novel approach to cancer treatment. Its active ingredient, entrectinib, inhibits tropomyosin receptor tyrosine kinases (TRKA, TRKB, and TRKC), which are encoded by the NTRK1, NTRK2, and NTRK3 genes. It also targets ROS1 and ALK, with IC50 values ranging from 0.1 to 2 nM, while showing weaker inhibition of JAK2 and TNK2 (IC50 > 5 nM). The primary active metabolite, M5, exhibits similar inhibitory activity against TRK, ROS1, and ALK. Fusion proteins involving TRK, ROS1, or ALK kinase domains can promote tumor growth by excessively activating downstream signaling pathways, leading to uncontrolled cell proliferation. Entrectinib has demonstrated both in vitro and in vivo efficacy in inhibiting cancer cell lines across multiple tumor types carrying NTRK, ROS1, or ALK fusions. Additionally, it achieves steady-state brain-to-plasma concentration ratios between 0.4 and 2.2 in animal studies (mice, rats, and dogs) and has shown anti-tumor effects in mice with intracranial tumors driven by TRKA and ALK. ROZLYTREK is an orally administered, once-daily treatment approved for NTRK fusion-positive solid tumors and ROS1-positive NSCLC in several countries, including Australia, Canada, the EU, Israel, Japan, New Zealand, South Korea, Taiwan, and the US, with additional regulatory reviews ongoing worldwide. The recommended ROZLYTREK dosage for ROS1-positive NSCLC is 600 mg once daily, with or without food, until disease progression or unacceptable toxicity. For NTRK fusion-positive solid tumors, the ROZLYTREK dosage guidelines are as follows: Adults and pediatric patients with a body surface area (BSA) of ≥1.51 m²: 600 mg once daily Pediatric patients older than 6 months: 300 mg/m² to a maximum of 600 mg Pediatric patients between 1 month and 6 months: 250 mg/m² once daily Learn more about ROZLYTREK projected market size for ROS1 NSCLC @ ROZLYTREK Market Potential Receptor Tyrosine Kinase (ROS1) is an essential transmembrane receptor protein that regulates key cellular functions such as apoptosis, survival, differentiation, proliferation, migration, and transformation. It plays a pivotal role in various cancers, including glioblastoma, colorectal cancer, gastric adenocarcinoma, inflammatory myofibroblastic tumor, ovarian cancer, angiosarcoma, and NSCLC. A ROS1 inhibitor is a drug designed to block the activity of abnormal ROS1 fusion proteins present in certain cancer cells. By inhibiting this protein, these inhibitors help restrict cancer cell growth and metastasis. As a type of targeted therapy, ROS1 inhibitors also act on multiple kinases, including Anaplastic Lymphoma Kinase (ALK) and Mesenchymal Epithelial Transition (MET), alongside ROS1. These inhibitors specifically target the kinase domain of ROS1, with conventional kinases classified into DFG-in (active, type I) and DFG-out (inactive, type II) based on their domain structure. For patients with stage IV ROS1-positive NSCLC, treatment with a ROS1 tyrosine kinase inhibitor (TKI) is recommended. ROS1 inhibitors have demonstrated remarkable efficacy in treating NSCLC, encompassing both approved therapies and emerging treatments under development. They have significantly advanced NSCLC management, establishing themselves as a crucial therapeutic approach. The current market for ROS1-positive NSCLC is largely dominated by TKIs such as XALKORI. According to DelveInsight's analysis, the market size for ROS1 inhibitors in NSCLC across the 7MM was valued at approximately USD 290 million in 2023, with the United States contributing the largest share. The market for ROS1 inhibitors is projected to experience substantial growth in the coming years. This expansion is driven by rising biomarker testing rates, a growing number of cancer diagnoses, increased awareness of ROS1 mutations, and the introduction of next-generation ROS1 TKIs. These advanced therapies offer improved CNS penetration and a broader range of coverage against ROS1 resistance mutations compared to first-generation TKIs.

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.

A single drug compound simultaneously attacks hard-to-treat prostate cancer on several fronts, according to a new study in mice and human cells. It triggers immune cells to attack, helps the immune cells penetrate the tumor, and cuts off the tumor's ability to burn testosterone as fuel, according to new research. A single drug compound simultaneously attacks hard-to-treat prostate cancer on several fronts, according to a new study in mice and human cells. It triggers immune cells to attack, helps the immune cells penetrate the tumor, and cuts off the tumor's ability to burn testosterone as fuel, according to new research from Washington University School of Medicine in St. Louis. The drug may offer a promising new strategy for treating patients whose tumors don't respond to standard therapy. The study appears online in the journal Nature Communications. Prostate cancer is notorious for eventually developing resistance to standard treatments that block or reduce testosterone, which fuels growth of these tumors. And like many solid tumors, prostate cancer also has proven stubbornly resistant to newer immunotherapies, which are intended to take the brakes off the immune system's T cells to get them fighting cancerous invaders. Immunotherapies -- most commonly, immune checkpoint inhibitors -- can be extremely effective but only in certain cancers, such as melanoma. "We need to develop better therapies for prostate cancer patients, because most of these tumors develop resistance to hormone-based therapies doctors rely on to treat these cancers," said senior author Nupam P. Mahajan, PhD, a professor of surgery. "Immunotherapy is the newest and most promising type of therapeutic for cancer right now, but even so, immune checkpoint inhibitors have failed to do much against most solid tumors, including prostate cancer. This study was surprising because we found that this drug activates anti-cancer T cells in a novel way, and it also increases the T cells' ability to penetrate the tumor. This could lead to a more effective strategy for patients whose cancers are hard to treat." The drug, called (R)-9b, is a small molecule that blocks an oncogene, a gene that drives cancer. The researchers initially attributed the drug's success in mouse studies to its ability to reduce or eliminate androgen receptors in the prostate cancer cells. These receptors bind to testosterone and use the hormone to fuel tumor growth. The drug's ability to eliminate the androgen receptor differs from standard drugs that reduce the amount of testosterone in the body, and other drugs that block the androgen receptor's function as a transcription regulator. But because the new drug was so effective, Mahajan and his colleagues suspected something more was going on. The drug blocks a gene called ACK1. The researchers developed a strain of mice that totally lacked this gene in order to study what happens when it's missing. At first, the researchers were baffled by these mice. Mice missing an entire gene often have obvious problems. But these mice seemed fine. And when the researchers looked for tumor growth, they found very little. It was difficult to model cancer in these animals. "In most of these mice, when we introduced cancer cells as we typically do, there was no trace of a tumor," said Mahajan, also a research member of Siteman Cancer Center at Barnes-Jewish Hospital and Washington University School of Medicine. "In the few that did develop tumors, the tumors were small compared to those of wild-type mice. This was the first clue that something important was happening in mice missing this gene. We found that they were able to mount a robust immune response against the cancer cells." When different mice -- mice with this gene -- were implanted with human prostate tumors and given the drug that blocks this gene, it had the same effect: taking the brakes off the immune system and producing increased levels of certain types of T cells known to attack cancer. The drug also increased signaling molecules that allow the T cells to penetrate the tumor and kill cancer cells more effectively. The tumors in these (R)-9b treated mice were much smaller than those of mice in control groups. Given the drug's success in tumor penetration, the researchers investigated whether adding immune checkpoint inhibitors to treatment with the drug would be even more effective, taking the brakes off T cells in more than one way at the same time -- but there was no such improvement. "Surprisingly, we found that the immune checkpoint inhibitor is activating ACK1, the very pathway we are shutting down with this drug compound," Mahajan said. "It's possible immune checkpoint inhibitors don't work well in these tumors because they are turning on ACK1, which suppresses the immune response. Similar to prostate cancer, the ACK1 pathway activation also could be employed by other cancers that do not respond to checkpoint inhibitors. However, these cancers could respond to (R)-9b, so we would like to investigate this drug in other solid tumors as well." Mahajan said the drug spurs multiple responses because of the nature of the gene it blocks. Many genes have several roles in the body, and ACK1's roles in expression of the androgen receptor and in reigning in the immune system make it an appealing target for cancer therapy, especially against solid tumors with a hormonal growth component, such as prostate and breast cancers. Mahajan has worked with Washington University's Office of Technology Management/Tech Transfer to on the use of this drug in cancer treatment. His team is gathering data to apply for permission from the Food and Drug Administration to test the drug in a clinical trial for patients with prostate cancer.
