Immutep s Partner, EOC Pharma,
Reports Completion of Recruitment of Phase I Study of Efti
SYDNEY, AUSTRALIA March 20, 2020 Immutep Limited (ASX: IMM; NASDAQ: IMMP) ( Immutep or the
Company ), is pleased to report that it has been informed its Chinese partner, EOC Pharma, has completed patient recruitment for the ongoing EOC202A1101 study being conducted in China. EOC Pharma is an oncology focused specialty pharmaceutical
company headquartered in Shanghai, China, and is the exclusive licensee of eftilagimod alpha ( efti or IMP321 ) from Immutep for the Chinese market. The last patient was enrolled and safely dosed in February 2020, bringing the
total number of participating patients to 12.
The EOC202A1101 study is taking place at the Fudan University Shanghai Cancer Center in China and is a
single-center, open label, fixed dose-escalation phase I study in MBC patients. Under the license, EOC Pharma is evaluating Immutep s lead product candidate, efti, in combination with chemotherapy agent, paclitaxel, in Chinese patients.
Participants are receiving either 6 mg or 30 mg doses of efti over the six-month treatment period to determine the safety, tolerability and efficacy of the combination treatment, along with the appropriate
dose for a potential phase II study.
Efti continues to have a good safety profile supported by the interim safety data from the trial. No serious adverse
events were reported from the combination therapy and no dose limiting toxicity events were observed in either dose group. Based on interim data and Immutep s published MBC data from Caucasian patients, the 30 mg dose of efti has already been
recommended for a registration clinical trial in Europe (Immutep s AIPAC trial).
EOC Pharma CEO, Xiaoming Zou, said: Our EOC202A1101
study is progressing well. The safety data so far is supportive of the 30 mg dose of efti for a potential registration trial in China. We look forward to seeing the readout of Immutep s phase IIb AIPAC trial in MBC patients in March. If the
AIPAC results are also positive, we will have confidence to move forward with our plans for the registration trial, deepening our partnership with Immutep.
EOC202A1101 Principle Investigator, Prof. Xichun HU, Director of Medical Oncology at Fudan University, said: It is encouraging to see the
combination therapy continues to demonstrate a good safety profile, consistent with other trials. As the study continues and more patients complete their treatment courses, we will be able to report efficacy data.

Immutep CEO, Marc Voigt stated: EOC Pharma are our partner for efti in China and we are excited
to see such strong progress being reported from their trial in MBC, particularly as we prepare to report results from our own late-stage breast cancer trial, AIPAC, this month.
Data is expected to be reported from EOC202A1101 during 2020, with study completion in Q4 CY2020. EOC Pharma holds the exclusive development and
commercialisation rights for efti in China, including Hong Kong, Macau, and Taiwan via a licensing agreement with Immutep. EOC Pharma will make further milestone payments to Immutep if efti achieves specific development milestones as well as
undisclosed royalties on sales. EOC Pharma refers to efti as EOC202 .
About the EOC202A1101 Trial
The EOC202A1101 study is taking place at the Fudan University Shanghai Cancer Center in China and is a single-center, open label, fixed dose-escalation phase I
study in 12 metastatic breast carcinoma patients. The study is evaluating Immutep s lead product candidate, eftilagimod alpha ( efti or IMP321 ), in combination with chemotherapy agent, paclitaxel, in Chinese patients.
Participants are receiving either 6 mg or 30 mg doses of efti over the six-month treatment period to determine the safety, tolerability and efficacy of the combination treatment, along with the appropriate
dose for a potential phase II study. The Chinese IND application for EOC202 (efti) was approved by the Chinese National Medical Products Administration (NMPA) in December 2017.
EOC Pharma is patient centric
organisation, combining products, capabilities and healthcare industry partners to support an integrated structure focused on the manufacturing, development and commercialisation of innovative oncology products. EOC strives to be the preferred
oncology partner of global biopharma and pharmaceutical companies, taking full advantage of the improving regulatory environment and strengthening clinical infrastructure in China in order to benefit the millions of patients who currently have
limited access to high quality oncology treatments.
