Focused Ultrasound Therapy

Early Stage squareFocused ultrasound is an early-stage, noninvasive, therapeutic technology with the potential to improve the quality of life and decrease the cost of care for patients with liver fibrosis. This novel technology focuses beams of ultrasound energy precisely and accurately on targets deep in the body without damaging surrounding normal tissue. The ultrasound enables the enhanced delivery of genetic therapy to treat liver fibrosis. This technique was successful in preclinical studies, but has not yet been translated to the clinic.

The primary options for treatment of liver fibrosis include medication and may eventually include liver transplantation.

For certain patients, focused ultrasound could provide a noninvasive alternative to surgery with less risk of complications and lower cost.

Advantages:

  • Focused ultrasound is noninvasive, so it does not carry added concerns like surgical wound healing or infection.
  • Focused ultrasound can reach the desired target without damaging surrounding tissue.
  • It can be repeated, if necessary.

Clinical Trials

At the present time, there are no clinical trials recruiting patients for focused ultrasound treatment of liver fibrosis.

Regulatory Approval and Reimbursement

Focused ultrasound treatment for liver fibrosis is not yet approved by regulatory bodies or covered by medical insurance companies.
