January 24, 2024 Don Tracy, Associate Editor New FDA guidelines require manufacturers to add boxed warnings to CAR T-cell therapy products. On January 19, 2024, the FDA issued multiple notifications to drugmakers requiring boxed warnings to be added to all chimeric antigen receptor (CAR) T-cell therapy products, citing additional cancer risks associated with the treatment. The agency states that the letters “notify manufacturers of each such licensed product to update the package insert to include available information related to the risks and to update the Medication Guide for these products to identify the possibility of the increased risk of getting cancers, including certain types of cancers of the immune system.” Treatments required to have updated warnings include all FDA-approved CAR T-cell therapies and licensed BCMA-directed and CD19-directed genetically modified autologous CAR T-cell immunotherapies. The letter stating these requirements has been sent to the manufacturers of Abecma, Breyanzi, Carvykti, Kymriah, Tecartus, ...
Eli Lilly said its experimental gene therapy restored hearing in a boy born with profound hearing loss. The results for this experimental treatment come three months after Regeneron Pharmaceuticals reported early but encouraging data for its hearing loss gene therapy. By FRANK VINLUAN Gene therapy made its first breakthroughs slowing vision loss from inherited eye disorders. Eli Lilly is making the ear this therapeutic modality’s next proving ground, and the pharmaceutical giant now has some encouraging early clinical trial results showing it can work. An 11-year-old boy with profound hearing loss experienced restored hearing within 30 days of receiving the gene therapy, AK-OTOF, Lilly announced Tuesday. These are results for just one patient—the first in a clinical trial that could enroll up to 150 participants. But this early result is a promising sign for the therapy, which Lilly gained in 2022 through the $487 million acquisition of its developer, Akouos. ...
Understanding tumor responses to drugs becomes challenging due to the complex nature of DNA replication, a critical target for many cancer treatments. All cells, including cancer ones, depend on a sophisticated system for DNA replication during cell division. Most chemotherapies aim to disrupt this replication process in rapidly multiplying tumor cells. Given the diverse genetic mutations in tumors, predicting drug resistance remains a formidable challenge. Now, scientists have developed a machine learning algorithm capable of predicting when cancer will resist chemotherapy. This model was specifically tested on cervical cancer, accurately predicting responses to cisplatin, a widely used chemotherapy drug. It efficiently identified tumors likely to resist treatment and shed light on the molecular mechanisms driving this resistance. Developed by the University of California San Diego School of Medicine (La Jolla, CA, USA; ), the algorithm assesses how various genetic mutations collectively impact a tumor’s response to DNA replication-inhibiting drugs. The ...
Opdivo plus Yervoy shows promise in treating patients with microsatellite instability-high or mismatch repair deficient metastatic colorectal cancer. Image Credit: Adobe Stock Images/Crystal light The combination of Bristol Myers Squibb’s Opdivo (nivolumab) with Yervoy (ipilimumab) showed significant improvements in progression-free survival (PFS) as a first-line treatment for patients with microsatellite instability-high (MSI-H) or mismatch repair deficient (dMMR) metastatic colorectal cancer (mCRC)in the Phase III CheckMate -8HW trial. The combination produced a 79% reduction in the risk of disease progression or death compared to chemotherapy, according to the trial. “Patients with MSI-H/dMMR metastatic colorectal cancer are less likely to benefit from chemotherapy,” said Thierry Andre, MD, head of the medical oncology department, Sorbonne University, Hospital Saint-Antoine, Paris, France, in a press release. “An impressive improvement in PFS and sustained benefit beginning at three months was observed with nivolumab plus ipilimumab versus chemotherapy in this trial. These results demonstrate ...
US-based Comanche Biopharma has raised $75m in an oversubscribed Series B financing round to develop its small interfering RNA (siRNA) therapy, CBP-4888, as a treatment for preeclampsia. The financiers included Google Ventures, F-Prime Capital, Lilly Asia Ventures, Longview Healthcare Ventures, New Enterprise Associates (NEA), and Atlas Venture. Furthermore, Scott Gottlieb from NEA and David Grayzel from Atlas will join Comanche’s board. Preeclampsia is persistent high blood pressure that develops during the second trimester of pregnancy or up to six weeks following delivery. It can be associated with high levels of proteins in the blood, decreased blood platelets, fluid in the lungs, or seizures. It occurs in 2-9% of pregnancies and the only management is premature delivery. Recent studies have found that excess circulating placental soluble fms-like tyrosine kinase 1 (sFlt1) is present in patients with preeclampsia, and can therefore, contribute to its pathogenesis. A 2023 study found that the administration ...
Pharmaceutical Executive Editorial Staff Vertex Pharmaceuticals’ and CRISPR Therapeutics’ Cas9 therapy Casgevy approved as a one-time treatment for transfusion-dependent beta thalassemia on the heels of its approval last month for sickle cell disease. The FDA has granted another approval to Vertex Pharmaceuticals’ and CRISPR Therapeutics’ gene-editing therapy Casgevy (exagamglogene autotemcel [exa-cel]) as a one-time treatment for transfusion-dependent beta thalassemia (TDT) in patients 12 years of age and older.1 Last month, Casgevy became the first FDA-approved novel genome editing technology for sickle cell disease (SCD), which was a significant advancement in gene therapy. The latest approval was months ahead of the FDA’s assigned Prescription Drug User Fee Act (PDUFA) date. “We are pleased with the approval of Casgevy in TDT well ahead of the PDUFA date,” said Samarth Kulkarni, PhD, chairman and chief executive officer of CRISPR Therapeutics.2 “The approval is a reflection of the power and versatility of the CRISPR ...
Startup TrX1 develops cell therapies that function like a particular type of regulatory T cell, or Treg, whose role includes dampening inflammation and inducing long-term tolerance. Based on research from Stanford, TrX1’s lead program is a potential therapy for preventing graft-versus-host disease. By FRANK VINLUAN Post a comment / Jan 17, 2024 at 6:04 PM When immune cells go awry and spark inflammation, a different type of immune cell stands ready to counteract that effect and return the immune system to a state of balance. Therapies based on such cells are part of an emerging area of research for the treatment of a wide range of autoimmune diseases. The work of Tr1X focuses on a particular type of these cells and the startup has emerged from stealth with $75 million and a lead program on track for the clinic later this year. The cells that tamp down excessive immune responses ...
Three years after bringing Jaguar Gene Therapy out of stealth, Deerfield Management is leading the funding of a manufacturing spinout from the Illinois company. Deerfield, with the help of ARCH Venture Partners and Nolan Capital, is backing a new company—Advanced Medicine Partners—which was formerly responsible for Jaguar’s chemistry, manufacturing and controls (CMC). The new firm seeks to provide best-in-class development of advanced medicines, including gene and cell therapies, addressing quality and scaling issues that have hindered new treatments. The management and technical teams have directed the CMC work of several approved products, including three gene therapies. In a release, CEO Andrew Knudten touted the experience of Advanced Medicine Partners’ genetic medicines team, which has manufactured roughly 350 non-GMP batches and supplied more than 20 preclinical studies. “With so many biotechnology companies being slowed or halted due to manufacturing challenges including product quality and scalability, we have the experienced people and ...
The FDA approved Vertex Pharmaceuticals’ gene therapy Casgevy for treating beta thalassemia, an inherited blood disease that leads to low levels of functioning hemoglobin. Last month, the one-time treatment won its first FDA nod for treating sickle cell disease. By FRANK VINLUAN A one-time CRISPR-based gene therapy developed by Vertex Pharmaceuticals and CRISPR Therapeutics now has an additional FDA approval as a treatment for the rare blood disease beta thalassemia. The affirmative decision announced Tuesday for the therapy, Casgevy, was widely expected following its December approval in sickle cell disease, but it comes more than two months early. The target date for an FDA decision in the beta thalassemia indication was March 30. Casgevy won its first ever regulatory approval in the United Kingdom, a November decision that covered both sickle cell disease and beta thalassemia. Beta thalassemia is an inherited disease in which genetic mutations lead to low levels ...
