Moffitt Cancer Center Melanoma Expert Reviews Unique Adverse Events with Newly Approved Drug

22.08.2012
An internationally recognized melanoma researcher at Moffitt Cancer Center and colleagues at the University of Kiel in Germany, including Axel Hauschild, M.D. and Katharina C. Kähler, M.D., have published an article in the current issue of The Journal of Clinical Oncology that describes immune-related adverse events for patients receiving either tremelimumab or ipilimumab, the latter a drug approved last year by the U.S. Food and Drug Administration for treating metastatic melanoma and other cancers.
Both drugs are anti-CTLA-antibodies with similar mechanisms of action, but manufactured by different companies. Ipilimumab is an immunoglobulin G1 with a plasma half-life of 12-14 days. Tremelimumab is an immunoglobulin G2 with a plasma half-life of 22 days. Both have been extensively tested in metastatic melanoma and ipilimumab has been approved for use in patients with metastatic melanoma.

“During treatment with ipilimumab and tremelimumab, a unique set of adverse events may occur called ‘immune-related adverse events,’ or irAEs,” said study lead author Jeffery S. Weber, M.D., Ph.D., director of Moffitt’s Donald A. Adam Comprehensive Melanoma Research Center of Excellence. “These irAEs may include colitis, hepatitis, pancreatitis, lymphadenopathy, neuropathies and nephritis.”

According to Weber, appropriate management of these side effects requires the cooperation of a multidisciplinary physician-led team that includes nurse practitioners and infusion nurses. Additionally, he recommends that specialists, including gastroenterologists, endocrinologists, hepatologists, dermatologists and surgeons, need education on managing these symptoms. Early recognition of irAEs and initiation of treatment are crucial, said Weber and his colleagues.

In their review of studies on the drugs’ adverse effects, the researchers also found that irAEs correlated with treatment response in some studies. The reduction in tumor burden came in four different patterns after week 12 of treatment.

“Anti-CTLA-4 antibodies have shown patterns of anti-tumor response that are different from responses to conventional chemotherapy,” explained Weber. “Because responses can occur slowly, or be mixed, 12 weeks has been the time to first evaluation with ipilimumab.”

Weber and his colleagues also reviewed the new set of response criteria that have been created – immune related response criteria or irRC – to evaluate disease progression and benefit with immune checkpoint inhibitors like ipilimumab. The irRC criteria have been compared with modified World Health Organization criteria in studies of patients receiving ipilimumab and can provide valuable information to oncologists as to when to stop treatment with ipilimumab, and when to continue.

“In this study, we provide a detailed description of irAEs and recommendations for practicing oncologists who are managing them along with the unusual kinetics of response associated with ipilimumab therapy,” said Weber.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
