Dragonfly Therapeutics has entered a clinical collaboration with Gilead Sciences to assess the potential of its investigational drug candidate DF1001 with the latter’s Trodelvy for two cancer indications. The study of the combination regimen will focus on metastatic breast cancer (mBC) and non-small cell lung cancer (NSCLC). DF1001 is designed to act on natural killer (NK) cells and T-cell activation signals, leveraging co-stimulation of NK receptor NKG2D and CD16 for NK cell activation. Trodelvy is a Trophoblast cell-surface antigen 2-directed antibody-drug conjugate. Dragonfly will maintain operational control of the trial, with the first patients receiving the combination treatment in the second quarter of 2024. Study sites are already operational in the US, Belgium, France, Denmark and the Netherlands. The study is set to expand, with additional sites in Europe, North America and Asia Pacific. Developed using Dragonfly’s TriNKET platform, DF1001 is being evaluated in adult patients for the treatment of ...
Pfizer announced a partnership with the American Cancer Society aimed at reducing disparities in cancer treatment. As part of the initiative, Pfizer is providing $15 million in funding. This money will go towards improving the health outcomes of cancer patients from underrepresented communities in the United States. This will include working to improve access to cancer screenings, clinical trial opportunities, and patient care. In a press release, Pfizer’s chief oncology officer and executive vice president Chris Boshoff said, “Cancer doesn’t discriminate–and neither should cancer care. Everyone should have the same opportunity to access the latest advances in care, regardless of their background or where they live. We’re proud to partner with the American Cancer Society on a broad, community-focused initiative to reach people living with cancer where they are, with urgency, and connect them to resources to receive the care they deserve.” The partnership will work under the banner of ...
This study was led by Professor Jin Li of Dongfang Hospital, Tongji University, with the participation of a total of 17 centers across China. Previously, four other indications of SHR-A1811 have been included in the list of breakthrough therapeutic varieties by the Drug Evaluation Center of the State Drug Administration, and the indications are: recurrent or metastatic breast cancer with low expression of HER2, HER2-positive recurrent or metastatic breast cancer, HER2-mutated advanced non-small-cell lung cancer that has failed previous platinum-containing chemotherapy, and advanced non-small-cell lung cancer that has failed previous treatments of oxaliplatin, fluorouracil, and irinotecan, and has failed previous treatments of oxaliplatin, fluorouracil, and irinotecan. irinotecan treatment failure, and HER2-positive colorectal cancer. In 2020, gastric cancer ranks 5th in global cancer incidence and 4th in mortality. HER2-positive gastric cancer is a unique disease subtype that requires different treatment strategies from HER2-negative gastric cancer. The global HER2-positive rate of gastric ...
When cells die, they disintegrate, releasing part of their DNA material into the bloodstream. This cell-free DNA (cfDNA) contains cancer signals. The cfDNA from healthy cells breaks down into standard-sized fragments, whereas cancerous cfDNA fragments disintegrate at different locations, often in the genome’s repetitive regions. Instead of searching for specific DNA mutations, which is like finding a single misarranged letter in billions of letters, researchers have developed a novel machine-learning method. This method detects variations in fragmentation patterns between cancerous and normal cfDNA in these repetitive regions of cancer. This groundbreaking technique could potentially allow for earlier cancer detection in patients through smaller blood samples, as it requires approximately eight times less blood than what is needed for whole genome sequencing. The algorithm called Alu Profile Learning Using Sequencing (A-Plus) was developed by researchers at City of Hope (Duarte, CA, USA) and Translational Genomics Research Institute (TGen, Phoenix, AZ, USA). ...
Gilead Sciences said even though Trodelvy missed the main goal of its Phase 3 test in non-small cell lung cancer, the drug’s preliminary results show numerical improvement in patients whose disease did not respond to prior treatment with immunotherapy. The company plans to discuss with regulators a possible path forward in these patients. By FRANK VINLUAN Sales for Gilead Sciences cancer drug Trodelvy are growing, but the company is counting on additional approvals to boost the product to blockbuster status and justify the premium price it paid to acquire the therapy. The drug’s failure in a pivotal lung cancer study is a setback to that strategy. Treatment with Trodelvy, an antibody drug conjugate (ADC), fell short of a Phase 3 study’s main goal of showing statistically significant improvement in overall survival in patients with advanced cases of non-small cell lung cancer (NSCLC), Gilead announced Monday. Nevertheless, the company pointed to numerical ...
After crowning Keytruda as the first immunotherapy for advanced cervical cancer back in 2021, the FDA has awarded the drug another industry-first designation in an earlier stage of the tumor type. But again, the achievement was not perfect for Merck. Thanks to a new FDA nod, Merck’s Keytruda is the first PD-1 drug to be approved in combination with chemoradiotherapy to treat patients with stage 3 to 4a cervical cancer, the New Jersey pharma giant said Friday. This marks Keytruda’s 39th indication in the U.S. The approval, however, was narrower than expected. It came on the back of results from the Keynote-A18 trial, which showed a tumor progression benefit for the Keytruda-chemoradiation regimen in a broader patient population with earlier-stage cervical cancer. Keynote-A18 tested the Keytruda combo in patients whose cancer was as early as stage 1b2. Among the entire trial population, adding Keytruda to chemoradiotherapy slashed the risk of ...
Pharmaceutical Executive Editorial Staff Rinatabart sesutecan (Rina-S; PRO1184) is under evaluation for the treatment of patients with FRα-expressing high-grade serous or endometrioid platinum-resistant ovarian cancer. The FDA has granted Fast Track designation to ProfoundBio’s rinatabart sesutecan (Rina-S; PRO1184) to treat patients with FRα-expressing high-grade serous or endometrioid platinum-resistant ovarian cancer.1 The novel folate receptor alpha (FRα)–targeted antibody-drug conjugate (ADC) is comprised of an FRα-directed antibody linked to sesutecan, which is an investigational, cleavable hydrophilic linker, and the topoisomerase 1 inhibitor payload exatecan. “Our receipt of Fast Track designation from the FDA underscores our belief in the tremendous promise of Rina-S as a potential best-in-class FRα ADC to address the significant need for improved treatment options for advanced ovarian cancer,” said Naomi Hunder, chief medical officer of ProfoundBio, in a press release.1 “FRα is a highly prevalent antigen in ovarian cancer and Rina-S has shown encouraging antitumor activity and tolerability in ...
Johnson & Johnson’s acquisition of antibody drug conjugate developer Ambrx Biopharma comes as Novartis and Merck also unveiled M&A deals on the first day of the J.P. Morgan Healthcare conference. In a report, the investment bank said big pharmas are looking for deals involving de-risked assets. By FRANK VINLUAN Big pharmaceutical companies splashed out big bucks in 2023 to acquire or license antibody drug conjugates, or ADCs. The trend is continuing into the new year with Johnson & Johnson reaching a $2 billion deal to acquire clinical-stage Ambrx Biopharma. According to deal terms announced Monday, J&J will pay $28 cash for each Ambrx share, which is a 105% premium to the biotech’s closing stock price on Friday. In other biopharma deal announcements, Merck is paying $680 million to acquire Harpoon Therapeutics, a developer of targeted cancer therapies, and Novartis is buying autoimmune disease drug developer Calypso Biotech for $250 ...
A novel artificial intelligence (AI) tool, designed to interpret medical images with exceptional clarity, is set to revolutionize the way clinicians approach disease diagnosis and image analysis. This advanced tool, named iStar (Inferring Super-Resolution Tissue Architecture), was developed by researchers at the Perelman School of Medicine at the University of Pennsylvania (Philadelphia, PA, USA). It can assist healthcare professionals in diagnosing and treating cancers that might otherwise remain undetected. iStar offers an in-depth view of individual cells and a broader look at the full range of human gene activity, potentially revealing cancer cells that were nearly invisible earlier. This tool could play a crucial role in confirming whether cancer surgeries have fully removed malignancies and provide automatic annotations for microscopic images, marking a significant leap toward molecular-level disease diagnosis. One of the standout capabilities of iStar is its automatic identification of crucial anti-tumor immune formations known as “tertiary lymphoid structures,” ...
GSK gains rights to a Hansoh Pharma antibody drug conjugate that targets a protein abundant on lung cancer cells and other types of solid tumors.
