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.

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.
