June Announcements Drive Optimism For Subcutaneous Briumvi

Earlier this month, TG Therapeutics reported positive early results for a new under-the-skin version of BRIUMVI in patients with myasthenia gravis, a disease that causes muscle weakness. In a small early study involving 11 patients, most saw clear improvements in their daily symptoms after six months, the company said.

The treatment was generally safe and well-tolerated, with a profile similar to the current IV version already used for multiple sclerosis. The company has now started a new mid-stage trial to test combining BRIUMVI with another drug for faster initial relief followed by longer-term control.

Prior to that, the company also released encouraging early data showing that the under-the-skin shot is well absorbed by the body and works similarly to the IV version. The results supported dosing every two or three months instead of more frequent clinic visits and raised the possibility of convenient at-home self-injections in the future.
