German biopharma company CureVac (Nasdaq: CVAC) saw its shares rise 24%, to $7.94 on Friday, after it announced positive preliminary data from ongoing Phase I clinical programs in COVID-19 and seasonal flu, assessing both modified and unmodified mRNA technology.
The vaccine candidates are being developed in collaboration with UK pharma major GSK (LSE: GSK), but the partners still lag behind rivals in the race to expand use of mRNA technology. In October 2021, CureVac announced that it was withdrawing its first vaccine candidate, CVnCoV, from the current approval process with the European Medicines Agency (EMA), after trial results fell short of the level required for statistical success.
The preliminary results generated by this broad technology approach showed that vaccine candidates using a modified second-generation mRNA backbone produced promising immunogenicity and reactogenicity profiles in both indications. Based on these preliminary data, development of modified mRNA COVID-19 and flu vaccine candidates will be advanced to the next stage of clinical testing in 2023.
