Innate Pharma: First Patient Dosed in Monalizumab Phase 3 Lung Cancer Clinical Trial Triggers $50M Payment From AstraZeneca

  • First patient dosed in Phase 3 trial, PACIFIC-9, evaluating durvalumab in combination with monalizumab or oleclumab in patients with unresectable, Stage III non-small cell lung cancer
  • Milestone payment further bolsters Innate’s cash position
  • Second Phase 3 monalizumab trial now initiated by AstraZeneca

MARSEILLE, France--(BUSINESS WIRE)-- Regulatory News:

Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced that AstraZeneca (LSE/STO/Nasdaq: AZN) has now dosed the first patient in its Phase 3 clinical trial, PACIFIC-9, evaluating durvalumab (PD-L1) in combination with monalizumab (NKG2A) or AstraZeneca’s oleclumab (anti-CD73) in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) who have not progressed following definitive platinum-based concurrent chemoradiation therapy (CRT).

The purpose of the study, which is sponsored by AstraZeneca, is to determine if the addition of monalizumab or oleclumab to standard-of-care durvalumab improves outcomes for patients in this setting.

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

Dosing of the first patient in this trial has triggered a $50 million milestone payment from AstraZeneca to Innate.

“We are very pleased that our key late-stage asset, monalizumab, has progressed into a second Phase 3 trial with our partner, AstraZeneca. The launch of PACIFIC-9 represents an important financial milestone for Innate, as it triggers a $50 million milestone payment that reinforces our cash position,” said Mondher Mahjoubi, Chief Executive Officer of Innate Pharma. “Based on the recent COAST clinical trial results, we are excited about the potential of extending the clinical benefit of durvalumab with the addition of monalizumab in patients with unresectable, Stage III NSCLC.”

Detailed results from the randomized COAST Phase 2 trial were published in the Journal of Clinical Oncology on April 22, 2022. AstraZeneca initially presented the results during the European Society for Medical Oncology (ESMO) Congress 2021 in September 2021 (see AstraZeneca press release). The results of the interim analysis showed monalizumab in combination with durvalumab increased objective response rate (ORR) and prolonged progression-free survival (PFS) versus durvalumab alone in patients with unresectable, Stage III NSCLC who had not progressed after CRT. The Journal of Clinical Oncology publication now includes exploratory subgroup analysis.

“Durvalumab has transformed the treatment of patients with unresectable, Stage III NSCLC, and we’re excited by the promise of extending its benefit through novel combinations with two potential first-in-class monoclonal antibodies demonstrating strong clinical activity. Based on the stand-out results from COAST, we are pleased that the Phase 3 trial is underway, which we hope will bring new treatment options to patients and further increase the potential for long-term survival benefit in this setting,” said Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca.

About PACIFIC-9:

PACIFIC-9 is a Phase 3, randomised, double-blind, multicenter global study to determine the efficacy and safety of durvalumab alone or in combination with oleclumab or monalizumab+ in patients with unresectable, Stage III NSCLC who have not progressed on definitive, platinum-based CRT.​

The first patient has been dosed in April 2022. The PACIFIC-9 Phase 3 trial is now looking to recruit patients across more than 200 centers in the coming months. ​

Stage III NSCLC:

In 2020, an estimated 2.2 million people were diagnosed with lung cancer worldwide1. Lung cancer is broadly split into NSCLC and small cell lung cancer, with 80-85% classified as NSCLC.2,3,4 Stage III NSCLC represents approximately one quarter of NSCLC incidence5.

Stage III (locally advanced) NSCLC is commonly divided into three subcategories (IIIA, IIIB and IIIC), defined by how much the cancer has spread locally. In contrast to Stage IV, when cancer has spread (metastasised), the majority of Stage III patients are currently treated with curative intent2,6.

The majority of Stage III NSCLC patients are diagnosed with unresectable tumours2,5.

About Monalizumab:

Monalizumab is a potentially first-in-class immune checkpoint inhibitor targeting NKG2A receptors expressed on tumor infiltrating cytotoxic CD8+ T cells and NK cells.

NKG2A is an inhibitory checkpoint receptor for HLA-E. By expressing HLA-E, cancer cells can protect themselves from killing by NKG2A+ immune cells. HLA-E is frequently overexpressed in the cancer cells of many solid tumors and hematological malignancies. Monalizumab may reestablish a broad anti-tumor response mediated by NK and T cells, and may enhance the cytotoxic potential of other therapeutic antibodies7.

The ongoing development for monalizumab is focused on investigating monalizumab in various combination strategies in different malignancies, including the Phase 2 NeoCOAST trial in the neoadjuvant early-stage setting.

About the Innate-AstraZeneca monalizumab agreement:

In October 2018, AstraZeneca obtained full oncology rights to monalizumab by exercising its option under the co-development and commercialization agreement initiated in 2015.

The financial terms of the agreement include potential cash payments up to $1.275 billion to Innate Pharma. Including the $50 million payment triggered by dosing the first patient in the Phase 3 PACIFIC-9 clinical trial, Innate Pharma has received $450 million to date.

For any commercialized oncology indication, AstraZeneca will book all sales revenue and will pay Innate low double-digit to mid-teen percentage royalties on net sales worldwide except in Europe where Innate Pharma will receive 50% share of the profits and losses in the territory. Innate will co-fund 30% of the costs of the Phase 3 development program of monalizumab with a pre-agreed limitation of Innate’s financial commitment.
