Det er en stor gåte og antagelig en av hovedgrunnene til Nanos kursfall. En hver aksjonær ville jo gitt full gass med å få ferdig kohort 2.
Det vi vel vet er at 2 pasienter var behandlet ferdig i februar i år. Men en ble regnet som eligible.
Det er gitt noen kommentarer fra Nano underveis i 1Q20 faktisk. Men som man ser har Nano ikke klart å holde dette, skyldes nok korona. Men svar bør nok snart komme.
"The Archer-1 study is an important study for us. The primary objective of the Archer-1 study is to evaluate the safety and tolerability of Betalutin® in combination with Rituximab. The secondary objective is to evaluate the preliminary anti-tumor activity of combination treatment.
In September 2019, at the latest R&D day, we communicated the preliminary results of the first safety cohort (10 MBq/kg Betalutin®): no dose-limiting toxicity and an ORR of 100% (3 CRs). We are currently enrolling patients in the 2nd safety cohort, where the dose has increased to 15 MBq/kg Betalutin® and we need to enrol 3-6 patients. We still expect the patients in the 2nd cohort to be enrolled in 1H 2020.
We will communicate when we have finalised the enrolment of the 2nd cohort. Once we have reviewed the data generated in the dose escalation part, we will communicate the next steps of the study, including size and timing of the extension phase."
