First quarter of 2020 and recent pipeline highlights:

COVID-19 Impact:

As we navigate the COVID-19 pandemic, we are dedicated to supporting our patients, our employees and their families, and the communities where we live and work.

Currently, there is varying impact to our pipeline assets in relation to COVID-19, as outlined below. The COVID-19 pandemic could impair our ability to achieve our product development or commercialization objectives in the timeframes we had expected.

We are closely monitoring the rapidly evolving environment and will continue to provide relevant information on our COVID-19 web page as the situation evolves.

ⁱIncluding short term investments (€16.3 million) and non-current financial instruments (€33.9 million).

Lumoxiti, a first-in-Class marketed product in-licensed from AstraZeneca for the treatment of relapsed or refractory hairy cell leukemia:

• In January, we announced that the European Medicines Agency (EMA) validated the Marketing Authorization Application (MAA) for Lumoxiti.
• In March 2020, the Biologics License Application for Lumoxiti was transitioned from AstraZeneca (LSE/STO/NYSE: AZN) to Innate. The transition is on track to be completed in 2020.
• Due to the COVID-19 pandemic, widespread restrictions and social distancing measures have limited opportunities for in-person marketing of Lumoxiti to oncology healthcare professionals and access to physicians causing interruptions of treatments for patients. As a result, the rate of new Lumoxiti patients has slowed which is expected to impact 2020 sales.

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

• At the ASCO20 Virtual Scientific Conference, new efficacy data will be presented from a Phase II expansion cohort of IO-pretreated patients.
  • ASCO abstract (Abstract #6516, Poster#177), entitled “Combination of Monalizumab and Cetuximab in Patients with Recurrent or Metastatic Head and Neck Squamous Cell Cancer Previously Treated with Platinum-based Chemotherapy and PD-(L)1 Inhibitors.”
• The advancement of monalizumab in combination with cetuximab to a Phase III trial in IO-pretreated patients suffering from recurrent or metastatic (R/M) squamous cell carcinoma of the head and neck (SCCHN) is expected in 2020.
• A controlled, randomized, study will explore monalizumab, amongst other treatment arms, to investigate the potential efficacy versus standard of care against COVID-19 in cancer patients with mild symptoms. This study is sponsored by Centre Léon Bérard, Lyon.

Lacutamab (IPH4102, anti-KIR3DL2 antibody):

• In January, the French and UK regulatory agencies agreed the lacutamab TELLOMAK trial could resume recruitment in Sézary syndrome and mycosis fungoides patients. In all other geographies, no new patients may be enrolled in the trial until a new Good Manufacturing Practice (GMP)-certified batch is available. Currently enrolled patients can continue treatment in the trial except in Italy.
  • New batches of drug product have been successfully manufactured. A new clinical GMP-certified batch is on track to be available in the second half of 2020.
  • The Company is progressing PTCL in alternative clinical development pathways and therefore, has taken the decision to stop the PTCL cohort in the TELLOMAK study.
• Due to slower clinical trial recruitment as a result of the regulatory status of TELLOMAK, compounded by the COVID-19 pandemic, potential delays in clinical development timelines may occur. The Company will provide an update in due time.

Avdoralimab (IPH5401, anti-C5aR antibody):

• The first patient was dosed in a randomized, double-blind, placebo-controlled, FORCE clinical trial, evaluating the safety and efficacy of its anti-C5aR antibody, avdoralimab, in COVID-19 patients with severe pneumonia.
  • The Phase II trial is supported by an exploratory translational study, EXPLORE, which suggests that patients who progress towards severe COVID-19 disease exhibit an increase of the C5a/C5aR pathway.
• A controlled, randomized, study will explore avdoralimab, amongst other treatment arms, to investigate the potential efficacy versus standard of care against COVID-19 in cancer patients with pneumonia. This study is sponsored by Centre Léon Bérard, Lyon.

IPH5201 (anti-CD39 antibody), partnered with AstraZeneca:

• In February 2020, the multicenter, open-label, dose-escalation Phase I trial started, which is evaluating IPH5201 as monotherapy or in combination with durvalumab (anti-PD-L1) with or without oleclumab (anti-CD73) in advanced solid tumors.
  • The Phase I clinical trial evaluating IPH5201 in adult patients with advanced solid tumors has reactivated, following a temporary pause due to the COVID-19 pandemic.

Post-period events:

• Following the dosing of the first patient on March 9, 2020 in the IPH5201 Phase I clinical trial, AstraZeneca made a $5.0 million milestone payment in April to Innate Pharma. In May, Innate made a €2.7 million milestone payment to Orega Biotech SAS pursuant to Innate’s exclusive licensing agreement.

Financial results:

Cash, cash equivalents and financial assets of the Company amounted to €206.9 million as of March 31, 2020. At the same date, financial liabilities amounted to €19.3 million.

During the first quarter of the year 2020 notably:

• A $15.0m (€13.4m) milestone payment was made to AstraZeneca in January 2020 following the submission by AstraZeneca of the Marketing Authorization Access relating to the commercialization of Lumoxiti in Europe.
• A €5.8m adverse variance in the fair value of our financial instruments was booked, resulting from the impact of the COVID-19 crisis on the financial markets.

Revenues for the first three-months of 2020 amounted to €19.3 million (€13.9 million for the same period in 2019). For the three-month period ended March 31, 2020, revenue from collaboration and licensing agreements mainly results from the spreading of the initial payments received under our agreements with AstraZeneca.
