Innate Pharma Third Quarter 2021 Report

  • Monalizumab in combination with durvalumab significantly delayed disease progression in AstraZeneca’s randomized Phase 2 COAST study in unresectable, Stage III NSCLC, advancing to Phase 3

  • Pre-clinical data presented at SITC with Sanofi from the lead next-generation NK cell engager platform, ANKET™ targeting CD123 in acute myeloid leukemia 

  • Cash position of €141.8 million  as of September 30, 2021

  • Conference call to be held today at 2:00 p.m. CET / 8:00 a.m. ET

Innate Pharma SA (Euronext Paris: IPH; Nasdaq: IPHA) (“Innate” or the “Company”) today announced its revenues and cash position for the first nine months of 2021.

In the period, we continued to execute against our strategic priorities as we reported readouts from two of our partnered portfolio programs. This included randomized Phase 2 data for monalizumab in combination with durvalumab in unresectable, Stage III NSCLC as well as pre-clinical data from our lead ANKET molecule targeting CD123 in acute myeloid leukemia. These readouts continue to set the stage for delivering both near and long-term value, while also highlighting the strength and depth of our core R&D efforts,” said Mondher Mahjoubi, Chief Executive Officer of Innate Pharma.  “Looking ahead, we will continue to advance our lacutamab development program and move our early-stage R&D activities towards the clinic with our next generation ANKET platform. We also look forward to seeing AstraZeneca’s upcoming plans for monalizumab’s registrational study in unresectable, Stage III NSCLC, which further reinforces our strategy of building a sustainable business with a robust R&D engine.


Webcast and conference call was held on November 16 at 2:00 p.m. CET (8:00 a.m. ET)

Pipeline highlights:

Monalizumab (anti-NKG2A antibody), partnered with AstraZeneca:

  • In September, AstraZeneca presented a late-breaker abstract on the randomized COAST Phase 2 trial in patients with unresectable, Stage III non-small cell lung cancer (NSCLC) at the European Society for Medical Oncology (ESMO) Congress. The presentation highlighted progression-free survival (PFS) and overall response rate (ORR) results for durvalumab in combination with monalizumab, Innate’s lead partnered asset, and oleclumab, AstraZeneca’s anti-CD73 monoclonal antibody. After a median follow-up of 11.5 months, the results of an interim analysis showed a 10-month PFS rate of 72.7% for durvalumab plus monalizumab, versus 39.2% with durvalumab alone in unresectable, Stage III NSCLC patients following chemoradiation therapy. The results also showed an increase in the primary endpoint of confirmed ORR for durvalumab plus monalizumab over durvalumab alone (36% vs. 18%).
  • Based on the data, AstraZeneca announced plans to initiate a Phase 3 trial for both combinations of monalizumab or oleclumab plus durvalumab in the unresectable, Stage III NSCLC setting for patients who had not progressed after concurrent chemoradiation therapy.
  • Separately, AstraZeneca also announced that it is starting a Phase 2 clinical trial, NeoCOAST-2, that includes a treatment arm with durvalumab in combination with chemotherapy and monalizumab in resectable, early-stage NSCLC.
  • Innate will present data from the Phase 2 expansion cohort (‘cohort 3’), exploring the combination of monalizumab, cetuximab and durvalumab in first-line IO naïve patients with recurrent/metastatic squamous cell carcinoma of the head and neck, which was accepted as a mini oral presentation at the ESMO Immuno-Oncology (ESMO-IO) conference in December 2021.

Lacutamab (anti-KIR3DL2 antibody): 

  • Two parallel clinical trials to study lacutamab in patients with KIR3DL2-expressing, relapsed/refractory peripheral T-cell lymphoma (PTCL) are initiating: 

◦    Phase 1b trial: a Company-sponsored Phase 1b clinical trial to evaluate lacutamab as a monotherapy in patients with KIR3DL2-expressing relapsed PTCL.  

◦    Phase 2 KILT (anti-KIR in T Cell Lymphoma) trial: The Lymphoma Study Association (LYSA) plans to initiate an investigator-sponsored, randomized trial to evaluate lacutamab in combination with chemotherapy GEMOX (gemcitabine in combination with oxaliplatin) versus GEMOX alone in patients with KIR3DL2-expressing relapsed/refractory PTCL. 

ANKET™ (Antibody-based NK cell Engager Therapeutics):


  • In November Innate and Sanofi shared new data on IPH6101/SAR443579 at the Society for Immunotherapy of Cancer (SITC) conference. IPH6101/SAR443579 is the first NKp46/CD16-based NK cell engager using Innate’s proprietary ANKETTM multispecific antibody format that targets CD123 on acute myeloid leukemia (AML) cells and co-engages NKp46 and CD16a on NK cells. 
  • IPH6101/SAR443579 demonstrated potent antitumor activity against AML cell lines and primary AML blasts, including those resistant to ADCC by a comparator anti-CD123 antibody. IPH6101/SAR443579 also promoted strong and specific NK-cell activation and induced cytokine secretion only in the presence of AML target cells. In addition, IPH6101/SAR443579 had sustained pharmacodynamic effects in non-human primates, combining efficient depletion of CD123-expressing cells with minor cytokine release and a favorable safety profile in comparison to T-cell engagers.

Tetra-specific ANKET

  • In September and November 2021, Innate also presented at the ESMO 2021 and SITC conferences respectively. Innate shared data from its tetra-specific ANKET molecule, which is the first NK cell engager technology to engage two NK cell activating receptors (NKp46 and CD16), a cytokine receptor (IL-2Rb) and a tumor antigen via a single molecule. In preclinical studies, the tetra-specific ANKET demonstrated in vitro the ability to induce human NK cell proliferation, cytokine production and cytolytic activity against cancer cells expressing the targeted antigen. 
  • The tetra-specific ANKET also demonstrated in vivo anti-tumor efficacy in several tumor models, allowing regression of established tumors as well as control of metastasis, associated with increased NK cell infiltration, cytokine and chemokine production at the tumor site. ANKET also showed a pharmacodynamic effect, low systemic cytokine release and a manageable safety profile in non-human primates. 

IPH5201 (anti-CD39):

  • AstraZeneca is conducting a Phase 1 trial in solid tumors with IPH5201 alone or in combination with durvalumab. The data is expected to be presented in 2022.  

IPH5301 (anti-CD73):

  • The Company is initiating an investigator-sponsored Phase 1 trial of IPH5301 in collaboration with the Institut Paoli-Calmettes. 

Financial Results:

Cash, cash equivalents and financial assets of the Company amounted to €141.8 million as of September 30, 2021. At the same date, financial liabilities amounted to €16.1 million.

Revenues for the first nine months of 2021 amounted to €10.3 million (€33.6 million for the same period in 2020). For the nine-month period, ended September 30, 2021, revenue from collaboration and licensing agreements mainly results from the spreading of the payments received under our agreements with AstraZeneca and Sanofi.
