Roche Holding AG has started an experimental immunotherapy trial that has reached his mid-stage with very good results among lung cancer patients. With the new treatment that is still in the research and development stage, lung cancer patients with highest level of certain biomarkers have 50% more chances of survival.
The drug called MPFL2380A is a small part of new class designed to adjust the body’s immune system to fight off cancer by blocking a protein also known as Programmed Death Receptor ( PD-1), used by tumors to evade the body’s defense system.
Studies have experimented the treatment on 287 patients with previously treated non-small cell lung cancer. The Roche therapy reduced the risk by 53% in those with the highest levels of a certain biomarker, compared to those treated with classical chemotherapy methods.
An optimistic report was released for patients who had low levels of PD-L1, another protein that allows tumors to escape our body’s immune system. Patients with low levels of PD-L1 have increased chances of survival thanks to the new therapy that will soon be available on the market for larger masses of people.
“The greater the expression of PD-L1, the greater the benefit”, commented Sandra Holding, chief medical officer at Roche’s Genentech unit.
This is great news appearing before the annual meeting of the American Society of Clinical Oncology, where further details on the treatment and its effects will be unveiled. The present update was provided in a scientific summary, to probably prepare members for intense debate during the meeting.
Beyond its beneficial effects, the new treatment in lung cancer was also described as highly tolerated by patients. Few respiratory events were reported, with no other violent outbursts of side effects. Compared to the effects of chemotherapy, the MPFL2380A is better assimilated by cancer patients.
The medicine allows for tumors to shrink and eventually disappear and cease development in human bodies.
Tumors in people whose cancer had spread to the central nervous system were shrunk thanks to the new therapies envisioned by the pharmaceutical giants. Alectinib is the active substance that reacts with the components of a benign tumor and shrinks it considerably. More than 69% of patients with cancer spread to the brain or other parts of the central nervous system benefitted from a substantial health improvement after the Alectinib therapy.
Alectinib is addressed to patients with a genetic mutation under the name of ALK, responsible for more than 5% of lung cancers. From a financial standpoint, this is a Jackpot for Roche. New sales estimates raise to 183 million Swiss francs profit gained by 2020. The drug was already approved in Japan in July.
U.S Food and Drug Administration Company will analyze all data coming from Roche reports, as soon as the pharma organization submits consistent data from both trials: Alectinib and MPFL2380A therapy.
Roche isn’t the only company that performs tests on patients suffering from cancer. Opdivo works in a similar way to find new treatments and won US approval in March for a new release. Merck had a medicine under the name of Keytruda approved in September. It is very efficient in skin cancer therapies and it is also being tested in lung cancer.
