Sangamo shares collapse. Sangamo shares fell sharply today by 27%. This decline comes as a result of the termination of the cooperation agreement with the American company Pfizer. This is scheduled to start implementing the termination on April 21, 2025. This comes as a result of Pfizer's decision not to continue submitting requests for biological products and not to continue submitting the marketing license for the drug Gyroctocogene Vetylparvovic.
