FDA approves Israel's IceCure tumor-treating tech for liver, kidney cancer
IceCure uses probes to freeze tumors, killing the tissue. The tumor then disperses naturally.

IceCure, a Tel Aviv-based medical device company has received additional US Food and Drug Administration approval for its tumor-treating cryoablation technology.In an interview with The Jerusalem Post on Thursday, Tlalit Bussi Tel Tzure, IceCure’s vice president of business development and global marketing, said the company received its first approval by the FDA in 2010 following clinical trials and evaluations. The company was founded in 2006.“The cryoablation system only became commercial in 2014,” she explained. “We had already general FDA approval to treat benign and cancerous tissues, but we didn’t have a specific application, meaning which organ we are treating with the cryoablation system.”Tel Tzure explained the new FDA approval “allows us to expand our capabilities in the US, meaning we can now treat liver and kidney tumors that are cancerous with our system.”IceCure also received approval for ear, nose and throat application, “but we are not active in that application yet.”Asked how the system works, Tel Tzure explained that cryoablation is the destruction of the cancerous or benign tumor tissue by applying to it a very cold temperature.“We use liquid nitrogen in order to decrease the temperature at the tip of a probe, and we insert the probe into the body – into the tumor – under imaging,” she explained. “For example if done for a breast tumor, it will be done with an ultrasound, so that the doctor will be able to see the tumor and know where to insert the probe.”An illustrative image of IceCure's cryoablation probe being inserted into the body during a procedure.

During 2020, IceCure hopes to extend its activity in the US now that the company has this new FDA clearance and can offer its treatment to a larger population, especially as the number of cancer cases continues to rise.“We can expand our activity by offering better care for more patients around the globe as well.”IceCure, Tel Tzure said, is also being used in Europe and Asia.“In Europe we have the CE mark, which means we can treat breast cancer patients and treat cancerous breast tumors, while in the US we still don’t have FDA approval for this,” she added. “In Japan, we are treating lung cancer and bone cancer patients as well.”In Israel, the use of cryoablation technology is just beginning.“We have a system available in two hospitals in Haifa,” Tel Tzure highlighted. “At Bnai Zion Medical Center, we are doing a clinical trial on kidney cancer patients, we have treated more than 100 with very good results.”The system is also available in Elisha Hospital in Haifa, as well as in Hillel Yaffe Medical Center in Hadera and Ziv Medical Center in the North.“We are looking to extend our activity in Israel as well,” she added.
