SYDNEY, AUSTRALIA – 30 January 2023 – Immutep Limited (ASX: IMM; NASDAQ: IMMP) (“Immutep” or “the Company”), a biotechnology company developing novel LAG-3 related immunotherapy treatments for cancer and autoimmune diseases, provides an update on the ongoing development of its product candidates, efti and IMP761, for the quarter ended 31 December 2022 (Q2 Fiscal Year 2023).

EFTI DEVELOPMENT PROGRAM FOR CANCER

Planned late-stage trial in 1L NSCLC

The United States Food and Drug Administration (US FDA) granted Fast Track designation to efti in combination with pembrolizumab in October 2022 for the treatment of 1L NSCLC, which will be evaluated in the Company’s planned late-stage registrational trial. The designation was granted based on the encouraging Phase II clinical data in 1L NSCLC from the TACTI-002 all-comer trial in terms of PD-L1 status, presented at American Society of Clinical Oncology’s (ASCO) Annual Meeting in June 2022. It is the second Fast Track designation issued by the FDA for efti (the first is for 1L HNSCC) and offers the potential for expedited development and review.

TACTI-002 (also designated KEYNOTE-PN798) Phase II clinical trial

Immutep reported compelling new clinical data from the TACTI-002 trial evaluating efti in combination with MSD’s (Merck & Co., Inc., Rahway, NJ., USA) anti-PD-1 therapy KEYTRUDA^®^ (pembrolizumab) in 1L NSCLC via a late-breaking abstract oral presentation at the Society of Immunotherapy of Cancer (SITC) Meeting in November 2022. Immutep’s abstract was one of just nine to be showcased at the SITC 2022 press briefing, out of more than 1,500 abstract submissions.

The results showed an ORR of 40.4% in the all-comer PD-L1 trial, meeting the primary endpoint of the 1L NSCLC part of the trial. The ORR improved across all PD-L1 status groups by central assessment compared with data reported at ASC0 2022. Additionally, the interim median Duration of Response (DoR) of 21.6 months, compares favourably to historical controls. Promising results were also achieved in the secondary endpoint of interim median Progression Free Survival (PFS) with overall PFS of 6.6 months and 9.3 months in patients with a PD-L1 TPS (Tumour Proportion Score) >1% for which efti in combination with pembrolizumab has Fast Track designation.

TACTI-003 – Phase IIb clinical trial

In October 2022, the IDMC for Immutep’s Phase IIb TACTI-003 trial reviewed the initial safety data from the study and recommended the trial continue with no modifications. The IDMC also reviewed initial efficacy data, although this was not the primary focus of the analysis. The recommendation validates Immutep’s decision to evaluate efti in the 1st line HNSCC setting following an encouraging ORR of 29.7% regardless of PD-L1 expression and five complete responses (CR) reported in the 2nd line HNSCC setting in TACTI-002.

The Company also presented a Trial in Progress poster on the TACTI-003 study at the SITC 2022 meeting in November 2022. Recruitment is ongoing for the TACTI-003 trial, with more than 50% of the planned 154

patients enrolled till quarter end.

Planned Phase II/III trial in Metastatic Breast Cancer

Immutep reported the positive outcome of its follow-up Type C meeting with the US FDA regarding its late-stage clinical development plans for efti in conjunction with standard-of-care chemotherapy for the treatment of MBC in December 2022. The Company and the FDA have agreed to an integrated Phase II/III trial design to help inform a Biologics License Application (BLA).

Based on the encouraging efficacy, favourable safety and learnings from the randomised AIPAC Phase IIb trial (which administered efti and chemotherapy on different days and ceased chemotherapy at six months), patients will receive efti and paclitaxel on the same day and treatment will continue until disease progression. In addition to HER2–/HR+ metastatic breast cancer, the patient population has also been expanded to include triple-negative breast cancer (TNBC), an aggressive form of breast cancer with limited treatment options.

Subject to regulatory and ethics committee feedback, the Phase II portion of the trial is expected to begin in Q3 FY23 with a safety lead in of 6 to 12 patients who will be given a higher 90mg dose of efti (compared to the completed AIPAC trial). This will be followed by 58 patients for the randomised Phase II portion of the trial. Depending on the Phase II results and Immutep’s resources, the Phase III portion will commence.

Phase II trial in Soft Tissue Sarcoma

Trial preparations continued during the quarter for a new investigator-initiated Phase II clinical trial which was announced in September 2022. The trial will be conducted in collaboration with the Maria Skłodowska-Curie National Research Institute in Poland and will evaluate efti in combination with pembrolizumab and radiotherapy, prior to surgery, in up to 40 patients with select soft tissue sarcoma. The trial is expected to commence in H1 of calendar year 2023.

INSIGHT-003 – Phase I triplecombination with standard-of-care anti-PD-1 therapy and chemotherapy

Initial clinical data was reported from the investigator-initiated INSIGHT-003 trial in November at the SITC 2022 conference. The poster provided initial efficacy details on 11 of the 14 patients with metastatic NSCLC adenocarcinomas that had been enrolled as of the 14 October 2022 cut-off date, plus safety data on all 14 patients. The data shows the triple-combination approach is well-tolerated and provides promising early signals of therapeutic activity with an ORR of 72.7% (8/11) and a Disease Control Rate (DCR) of 90.9% (10/11).

INSIGHT-005 – New Phase I trial with Merck KGaA, Darmstadt, Germany, and Pfizer

Immutep signed a Clinical Trial Collaboration and Supply Agreement with Merck KGaA, Darmstadt, Germany and Pfizer in November 2022 for a new Phase I clinical study in patients with urothelial cancer, called INSIGHT-005. It is the second agreement entered into by Immutep with Merck KGaA and Pfizer and builds on the encouraging clinical data reported from the completed INSIGHT-004 study in multiple solid tumour indications from efti and avelumab (BAVENCIO^®^). Under the Agreement, Immutep and Merck KGaA will jointly fund the study, which is expected to start in mid-calendar year 2023.

Efti Manufacturing Scale-Up

Immutep successfully scaled-up the manufacturing process for efti with the completion of its first 2,000L manufacturing run by the Company’s manufacturing partner, WuXi Biologics. This large-scale manufacturing capability is a significant achievement. Immutep plans to introduce the material manufactured into ongoing and future Phase II/III clinical trials.

IMP761 DEVELOPMENT PROGRAM FOR AUTOIMMUNE DISEASES

During the quarter, Immutep established a GMP-compliant manufacturing process for IMP761, its proprietary preclinical candidate for autoimmune diseases. The 200L scale manufacturing process was developed by the Company’s manufacturing partner, Northway Biotech and will provide supply of IMP761 for Investigational New Drug (IND)-enabling studies and clinical trials.

INTELLECTUAL PROPERTY

Immutep was granted four new patents during the quarter. The first two patents were filed as divisional applications and were granted by the Japanese and South Korean Patent Offices. These patents protect Immutep’s intellectual property relating to combination preparations comprising efti and a chemotherapy agent which is oxaliplatin, carboplatin, or topotecan. They follow the grant of the Japanese parent patent and corresponding patents in the United States, Europe, China and Australia, as announced in 2019 through 2021.

The Company was granted another patent by the South Korean Patent Office, which relates to a potency assay for release testing of efti. The assay is used in Immutep’s commercial-scale (2,000L) manufacturing process.

Immutep was also granted a new patent by the Chinese Patent Office. The patent protects IMP731 in the territory of mainland China. The patent is co-owned with the French Institute of Health and Medical Research (INSERM) and exclusively licensed to GSK, Immutep’s development partner for IMP731.

FINANCIAL SUMMARY

Immutep’s financial performance over the quarter (Q2 FY23) continues to reflect prudent cash management. The Company’s cash runway was expanded to the end of FY24 (previously early H2 FY24).

Cash receipts from customers Q2 FY23 were $8k, compared to $33k in Q1 FY23. The Company received a A$986,286 cash rebate from the Australian Federal Government’s R&D tax incentive program in relation to expenditure incurred on eligible R&D activities conducted in Australia in the 2021 fiscal year.

The net cash used in G&A activities in the quarter was $734k compared to $595k in Q1 FY23.

Payments to Related Parties, detailed in Item 6 of the Appendix 4C cash flow report for the quarter, includes $402k in payment of Non-Executive Director’s fees and Executive Director’s remuneration.

The net cash used in R&D activities in the quarter was $5.87 million, compared to $7.17 million in Q1 FY23. The decrease was mainly due to a reduction in manufacturing activities during the quarter.

Total net cash outflows used in operating activities in the quarter were $7.02 million compared to $6.35 million in Q1 FY23.

Immutep’s cash and cash equivalent balance at 31 December 2022 was approximately $68.38 million, giving the Company an expected cash reach based on current estimates to the end of FY24. Immutep will continue to manage its strong cash balance carefully as it pursues its overall clinical development strategy.
