The virus, called NV1020, is a type of herpes simplex virus modified so that it selectively replicates in virus cells, killing them in the process.
“It doesn’t replicate in normal, healthy cells, so our hope is that it will help fight cancers without causing side-effects in the rest of the body,” said Dr. Axel Mescheder, VP Clinical Research & Development, from the Munich-based biotech company MediGene. The study is conducted in seven leading US-cancer centers, with Dr. Tony Reid from the University of California in San Diego, CA as Principal Investigator. Dr. Mescheder presented preliminary safety and efficacy results and a case report from this ongoing clinical trial in patients with colorectal cancer metastatic to the liver at the meeting.
Dr. Mescheder’s poster presentation described the case of a patient whose cancer had spread to 10 different places around the liver and four in the lungs. He was given the virus treatment in four weekly infusions direct into blood stream, followed by two cycles of approved chemotherapy.
Six months after treatment, scans showed the liver masses had nearly disappeared. “The reduction in the tumor masses was really impressive in this patient,” Dr. Mescheder said. “The hepatic masses almost disappeared.”
The patient survived for 12 months after treatment.
“In the current study, the scientists are testing the treatment in patients with colorectal cancer that have not responded to chemotherapy and where the cancer has spread to the liver,” Dr. Mescheder said. “We are hoping to extend overall survival.”
So far, the findings are looking positive. The treatment seems very tolerable for patients and safe. “The results are really quite encouraging at this early stage,” he said.
Almost 40% of patients with colorectal cancer ultimately die from metastatic disease, where the cancer spreads to other parts of the body. Most of the spreading occurs to the liver and 15% of patients have liver metastases at the time of diagnosis.
The latest human results reported today follow testing in the lab and in animals where the virus was shown to be effective at killing colorectal cancer cells and liver cancers.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
