SQZ Biotechnologies Co. shares advanced 44% to 87 cents in aftermarket trading Wednesday on news that its Phase 1 SQZ-AAC-HPV-101 clinical trial would continue.
Shares, which closed up 1.1% to 60 cents, are down nearly 89% over the last 12 months.
The clinical-stage biotechnology company said its trial would continue following an observation of a confirmed complete response in the first patient in its lowest-dose cohort.
"We remain focused on optimizing the potential of our eAPC and AAC platforms to meet the significant unmet medical needs of patients with HPV16+ tumors," said interim Chief Executive Howard Bernstein. Data from both of these programs will come later in the year, he said.
The trial is testing SQZ's activating antigen carriers, derived from red blood cells, to treat HPV16+ advanced or metastatic solid tumors.
