A "certain percentage" of participants in Zhejiang Wolwo Bio-Pharmaceutical's (SHE:300357) phase 1 clinical trial for its Aspergillus fumigatus prick solution showed a delayed reaction to the drug, according to a Thursday disclosure to the Shenzhen bourse.
Participants' delayed reaction to the drug suggests a "potential association with the fungal nature of Aspergillus fumigatus," the filing said.
Researchers are suggesting more optimal strategies to reduced the delayed reactions to the drug, the drug company said.
The drug showed a favorable safety profile within the established dose range of between 55 dosage units per milliliter and 495,000 dosage units per milliliter, the filing said.
