Pharmaceutical giant AstraZeneca will acquire biotechnology company Neogene Therapeutics for up to $320 million, the London-listed drugmaker said on Tuesday (November 29) as it seeks to build its pipeline of cell-based cancer treatments. Though AstraZeneca's oncology portfolio accounted for more than a third of the company's revenue last year, it does not have an approved cell-based cancer therapy and is behind rivals such as Novartis and Gilead. "Neogene's leading (T-cell receptor) discovery capabilities and extensive manufacturing experience complement the cell therapy capability we have built over the last three years," said Susan Galbraith, AstraZeneca's executive vice president of oncology research. Cell-based treatments are a relatively new approach to treating cancer, most of which involve drawing the body's own immune cells and processing them in the lab to target and kill cancer cells. Neogene's approach goes one step further in that its experimental T-cell receptor therapies seek to target DNA mutations specific to tumours, not only certain proteins on the surface of cancer cells.

Johnson & Johnson said on Wednesday (January 18) that it was pulling the plug on a late-stage global trial of an HIV vaccine after the shot was found ineffective at preventing infections. The failure of the trial marks yet another setback in the search for a vaccine against a virus known to mutate rapidly and find unique ways to evade the immune system, and comes more than a year after another of J&J's HIV vaccine failed a study. "It's not the outcome we had hoped for, unfortunately," said a spokesperson for the National Institute of Allergy and Infectious Diseases, a J&J partner in the trial. "The development of a safe and effective HIV vaccine has been a considerable scientific challenge, but we will learn from this study and continue forward." The trial involved administering two different types of a shot, which uses a cold-causing virus to deliver the genetic code of HIV, spread over four vaccination visits in a year. J&J used similar technology for its COVID-19 vaccine. The study, which began in 2019, was conducted at over 50 sites and included about 3,900 gay men and transgender people - groups that are considered vulnerable to the infection.

AstraZeneca said on Monday (June 27) two of its existing therapies were recommended for treating patients with some forms of high-risk breast cancers in the European Union, in a boost to the company's oncology portfolio. Lynparza, a cancer drug developed jointly with U.S.-based Merck, was backed for standalone use or in combination with endocrine therapy in adults with a form of genetically mutated early-stage breast cancer. The drug, which has received a similar recommendation in the United States in March, is a key asset for AstraZeneca. It was recommended in patients with low-to-normal levels of a protein known as HER2 that is the target of several new therapies. Enhertu - developed jointly with Japan's Daiichi Sankyo (4568.T) - was the other drug that was endorsed by the European Medicines Agency for treating an aggressive form of breast cancer characterised by a high rate of HER2.

The drug, alpelisib, which is the 100th cancer drug that has being fast-tracked to patients under the NHS Cancer Drugs Fund (CDF) will be used in combination with the hormone therapy, fulvestrant, to target the gene that causes fast-growing tumours. Up to 3,000 people a year with a certain type of secondary breast cancer will benefit from the treatment. The approach has contributed to people in England having access to nearly one third more cancer drugs compared to the European average. The drug which is manufactured by pharmaceutical company Novartis, is part of a growing number of precision treatments that target a tumour based on mutations in its DNA and that the NHS is rolling out. John Stewart, NHS National Director for Specialised Commissioning said, "In just over five years, more than 80,000 people have benefitted from earlier access to a range of cancer drugs, with people in England having access to nearly one third more cancer drugs compared to the European average, and this latest innovative new treatment will help up to 3,000 more to live a better quality of life.

French drugmaker Sanofi said on Monday (June 13) an upgraded version of the Covid-19 vaccine candidate it is developing with GSK showed potential in two trials to protect against the virus's main variants of concern, including the Omicron BA.1 and BA.2 strains, when used as a booster shot. While the two companies' first experimental Covid shot is undergoing review by the European Medicines Agency, Sanofi and GSK have continued work on a vaccine that is moulded on the now-supplanted Beta variant, hoping still that it will confer broad protection against future viral mutations. Sanofi said this new vaccine candidate was shown to significantly boost antibody levels against a number of variants of concern, when given to trial participants who had an initial course of mRNA vaccines, a type made by BioNTech-Pfizer and Moderna. In a separate trial conducted by a French hospitals network, Sanofi's Beta-adapted booster shot triggered a higher immune response than Sanofi's first-generation shot or Pfizer-BioNTech's established vaccine in previously vaccinated volunteers.

An oral drug combination by Novartis showed promise in treating a subgroup of patients suffering from a common childhood brain cancer in a trial. In the mid-stage trial, 47 per cent of the patients that were given the two drugs Tafinlar and Mekinist saw their tumours shrink, far above a rate of 11 per cent in a comparative group of participants on standard chemotherapy, the drugmaker said on Monday, June 6. The participants, aged one to 17 years, were suffering from low-grade gliomas (LGG), the most common childhood brain cancer. The trial only included those who were found to have a mutation known as BRAF V600, a genetic contributor in about 15 per cent to 20 per cent of paediatric LGG cases. Among further results of the trial with 110 participants, the median time without disease progression was 20.1 months for those given the Novartis drug combo, compared to 7.4 months on chemotherapy. The new oral treatment candidate also caused less severe side effects than burdensome chemotherapy.

The European Union's health regulator on Friday said it had recommended granting a conditional marketing authorisation for a gene therapy by Australian drugmaker CSL Ltd and partner uniQure N.V. , to treat haemophilia B, a rare bleeding disorder which is caused by genetic anomalies. About one in 40,000 people are affected by the inherited disorder, caused by a gene mutation that hampers the body's ability to make clotting protein factor IX. If approved, the treatment, branded Hemgenix, will be the first gene therapy in the European Union for the condition that is usually treated by regular injections of factor IX, the European Medicines Agency said. CSL had acquired exclusive global rights to Hemgenix in May last year from uniQure N.V.
