If, in the performance of this Agreement, one of the Parties is prevented, hindered or delayed by reason of any cause beyond such Party’s
reasonable control (e.g., war, riots, fire, strike, acts of terror, governmental laws), such Party shall be excused from performance to the extent that it is necessarily prevented, hindered or delayed (“Force Majeure”).

duration, and any action being taken to avoid or minimize its effect. The suspension of performance will be of no greater scope and no longer duration than is necessary and the non- performing Party shall use
commercially reasonable efforts to remedy its inability to perform. 
  

	17.	 Entire Agreement; Amendment; Waiver. 

This Agreement, together with the Appendices and Schedules hereto and the Related Agreements, constitutes the sole, full and complete agreement
by and between the Parties with respect to the subject matter of this Agreement, and all prior agreements, understandings, promises and representations, whether written or oral, with respect thereto are superseded by this Agreement. In the event of

Parties hereto. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of
the Party waiving such term or condition. The waiver by either Party of any right hereunder or of the failure to perform or of a breach by the other Party shall not be deemed a waiver of any other right hereunder or of any other breach or failure by
said other Party whether of a similar nature or otherwise. 

  
 Confidential material

INITIAL PRESS RELEASE 
  

 
 MSD FINAL 

20180306 Immutep - 

 

 
 ASX/Media Release (Code: ASX: IMM; NASDAQ: IMMP) 

[ ] March 2018 
 IMMUTEP ENTERS
INTO CLINICAL TRIAL COLLABORATION AND SUPPLY AGREEMENT WITH MSD 
 SYDNEY, AUSTRALIA - Immutep Limited (ASX: IMM; NASDAQ: IMMP)
(“Immutep” or the “Company”) has announced that it has entered into a clinical trial collaboration and supply agreement with Merck & Co., Inc., Kenilworth, NJ, USA (known as MSD outside the United States and Canada),
through a subsidiary, to evaluate the combination of Immutep’s lead immunotherapy product candidate eftilagimod alpha (“efti” or “IMP321”) with MSD’s anti-PD-1 therapy KEYTRUDA® (pembrolizumab) in a new clinical trial that will evaluate the combination in several different solid tumours. 

The planned Phase II clinical trial, referred to as TACTI-002 (Two ACTive Immunotherapies), will evaluate the safety and efficacy
of this novel immunotherapy combination in patients with non-small cell lung cancer (“NSCLC”), head and neck cancer, or ovarian cancer. The TACTI-002 clinical trial will be a Phase II, Simon two-stage, non-comparative, open-label,
single-arm, multicentre clinical study. Up to 120 patients across the three indications are planned to be treated in medical centres in Europe and the United States with the trial expected to commence in the second half of 2018. 

“We are extremely pleased to be collaborating with MSD, one of the world’s leading immuno-oncology companies” said Marc Voigt,
CEO of Immutep. “This clinical trial will evaluate a novel combination of two complementary immuno-oncology treatments in three cancer indications simultaneously, which could lead to more rapid drug development subject to successful outcomes.
The data generated thus far from our ongoing TACTI-mel clinical trial has supported our hypothesis that there is a compelling therapeutic synergy in administering efti in combination with another immuno-oncology treatment. This new Phase II clinical
trial significantly builds on the momentum we are delivering in the evaluation of efti in cancer, with two Phase I clinical trials and now two Phase II clinical trials in our program for 2018.” 

The trial combines two immuno-oncology treatments with complementary mechanisms of action, analogous to releasing the brakes and pushing the
accelerator of the body’s immune system at two different positions in the cancer immunity cycle. Immutep’s efti is a first-in-class antigen presenting cell (“APC”) activator which stimulates
cancer-fighting T cells, while KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the body’s immune system to help detect and fight tumor cells. 

About Immutep 
 Immutep is a
globally active biotechnology company that is a leader in the development of immunotherapeutic products for the treatment of cancer and autoimmune disease. Immutep is dedicated to leveraging its technology and expertise to bring innovative treatment
options to market for patients and to maximise value to shareholders. 
 Immutep’s current lead product is eftilagimod alpha
(“efti” or “IMP321”), a soluble LAG-3Ig fusion protein based on the LAG-3 immune control mechanism. This mechanism plays a vital role in the regulation of the T cell immune response. Eftilagimod alpha, alone or in combination
with other therapeutics, has completed early Phase II trials as an APC activator boosting T cell responses for cancer chemo-immunotherapy. Additional LAG-3 products, including antibodies, for immune response modulation in autoimmunity and cancer are
being developed by Immutep’s large pharmaceutical partners.
