Innate Pharma SA (NASDAQ: IPHA) stock soared 108% higher after AstraZeneca announced a joint clinical study’s positive phase 2 clinical trial data.


AstraZeneca revealed that the study, which combined Innate Pharma’s monalizumab and AZN’s durvalumab, had positive interim results when used as a combined dosage.

The interim trial results were presented at the European Society for Medical Oncology Congress 2021 earlier today, triggering a wave of buying pressure on Innate Pharma’s stock.

The two drugs improved progression-free survival and objective response rate compared to AZN’s durvalumab alone in patients with unresectable, Stage III non-small cell lung cancer.

Monalizumab, Innate's lead partnered asset, is a potentially first-in-class immune checkpoint inhibitor targeting NKG2A receptors expressed on tumour infiltrating cytotoxic CD8+ T cells and NK cells.

Based on the positive interim results, AstraZeneca informed Innate Pharma that it plans to start a registrational study with monalizumab in combination with durvalumab in patients with unresectable Stage III non-small-cell lung cancer.
