TGA is very difficult to study because of the patients quick recovery. This form of amnesia, like AA, remains distinct from RA.Post-traumatic amnesia (PTA) is a state of confusion that occurs immediately following a traumatic brain injury in which the injured person is disoriented and unable to remember events that occur after the injury. Psychogenic amnesia, or dissociative amnesia, is a memory disorder characterized by sudden retrograde autobiographical memory loss, said to occur for a period of time ranging from hours to years.

The Food and Drug Administration has granted a fast track designation to sotorasib for the treatment of metastatic non-small-cell lung carcinoma with the G12C KRAS mutation. Chemistry and pharmacology
Sotorasib can exist in either of two atropisomeric forms and one is more active than the other. It selectively forms an irreversible covalent bond to the sulfur atom in the cysteine residue that is present in the mutated form of KRAS, but not in the normal form. History
Researchers evaluated the efficacy of sotorasib in a study of 124 participants with locally advanced or metastatic KRAS G12C-mutated non-small cell lung cancer with disease progression after receiving an immune checkpoint inhibitor and/or platinum-based chemotherapy. The major outcomes measured were objective response rate (proportion of participants whose tumor is destroyed or reduced) and duration of response. The objective response rate was 36% and 58% of those participants had a duration of response of six months or longer.The U.S. Food and Drug Administration (FDA) granted the application for sotorasib orphan drug, fast track, priority review, and breakthrough therapy designations. The FDA collaborated with the Australian Therapeutic Goods Administration (TGA), the Brazilian Health Regulatory Agency (ANVISA), Health Canada and the United Kingdom Medicines and Healthcare products Regulatory Agency (MHRA). The application reviews are ongoing at the other regulatory agencies.The FDA granted approval of Lumakras to Amgen Inc.
