New lung cancer drug shows dramatic results for shrinking tumors

23.06.2010
Patients with a specific kind of lung cancer may benefit from a Phase III clinical trial offered by the Moores UCSD Cancer Center. The new drug, crizotinib, under development by Pfizer, showed dramatic results in reducing lung cancer tumors in some patients during Phase I and II clinical trials.

"The results of the first two trials have been very encouraging," said Lyudmila Bazhenova, MD, assistant clinical professor at UC San Diego School of Medicine and a member of the Moores UCSD Cancer Center. "The Phase III clinical trials will be critical in determining if this drug goes to market."

According to a preliminary study presented at the 2010 meeting of the American Society of Clinical Oncology, Phase I/II clinical trials demonstrated that 57% of patients had their tumors reduced and at eight weeks of the treatment, 87% showed disease stabilization.

In some patients with non-small cell lung cancer (NSCLC), the anaplastic lymphoma kinase (ALK) gene may move and fuse with another gene, EML4. The resultant fusion produces an enzyme that promotes lung cancer cell growth. This fusion happens in approximately four percent of NSCLC patients. The chances of a patient having the fusion gene increases if they have the adenocarcinoma subtype of lung cancer, or are non-smokers or former light smokers, among other characteristics. Those patients have an approximate 20% chance of having this mutation. Crizotinib inhibits the enzyme, allowing the cancer cells to die off.

The Phase III clinical trial will compare crizotinib with standard-of-care chemotherapy in the treatment of ALK-positive recurrent NSCLC. Through a randomized selection process, patients will either be treated with chemotherapy or crizotinib. If the patients who are given the chemotherapy do not respond to treatment, they will be given crizotinib at the end of the trial.

Candidates for the Phase III trial must have stage four NSCLC and have gone through at least one round of chemotherapy. If the patient qualifies for the study, they will be tested for the gene at the Moores UCSD Cancer Center. Potential candidates for the clinical trial should call the clinical trials hotline at (858) 822-5354.

According to the American Cancer Society, more than 220,000 new lung cancer cases will be diagnosed in the U.S. in 2010. Only four percent of those cases will qualify for this clinical trial, which equals approximately 9,000 patients for whom this drug may help stop the growth of cancer.

The Moores UCSD Cancer Center is one of the nation's 40 National Cancer Institute-designated Comprehensive Cancer Centers, combining research, clinical care and community outreach to advance the prevention, treatment and cure of cancer. For more information, visit http://health.ucsd.edu/cancer/

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
