Immutep Limited (IMM-AU)

Data highlights ei efficacy and potenal central role in cancer therapy

KEY TAKEAWAY

Data presented SITC (Society for Immunotherapy of Cancer) not only further supports eilagimod alpha ("ei") efficacy in metastac breast ("mBC") and head and neck ("HNSCC") cancers, but also highlights a potenal central role for ei across cancer therapy. Interim overall survival ("OS") from the AIPAC was already posive, this final data is slightly improved with a clear 2.9 month increase in OS with ei+ paclitaxel. While this was not stascally significant, there was a significant increase in quality of life ("QoL") across the populaon and in OS in large paent subgroups amounng to 60% of the populaon. This included paents <65 years, those pre-treated with CDK 46 treatment, with luminal B or parcularly with a low starng monocyte count where there was an impressive 19.6-month OS increase. Further data from Phase IIa TACTI-002 supported the efficacy of ei-pembrolizumab("ei-pembro") combinaon in HNSCC. These data not only support the connued development of ei in mBC in the AIPAC-03 Phase III and HNSCC in TACTI-003 Phase 2b, but also the broad potenal of ei combinaons in cancer therapy. Safe and well tolerated ei is already showing synergy with an-PD-L1 and chemo, we believe analysis of the mBC subgroups could lead to addional combinaons; parcularly with agents that impact monocyte acvity. We reiterate and maintain our OUTPERFORM recommendaon and AUD$ 1.350 target price.

Firm basis to move to Phase 3 in mBC: There is now a strong basis for movement into Phase 3, with significant increases in final OS of 7.5, 5.3, 4.2, and 19.6 months in paents <65years, CDK 46 pre-treated, with luminal B or with low starng monocytes respecvely. Although management is cauous in providing guidance on design with regulatory discussions ongoing, given that CDK 46 treatment is now standard and the impact of ei on QoL across the populaon, a standard of care ("SoC") all comers trial seems likely with close monitoring of the responsive paent groups. While AIPAC failed to achieve significance across the paent populaon, the AIPAC-03 Phase 3 will extend paclitaxel dosing beyond the six cycles used in Phase 2. This could boost the overall response. Given the strength of the AIPAC Phase 2 data and adopon of CDK 46 as SoC, we are opmisc for a posive outcome.

Strong results from TACTI-002 support Phase 2b entry: Encouraging results from their TACTI-002phase IIa trial has been reported HNSCC paents, with overall Response Rate (ORR) in 29.7% of 2nd line HNSCC paents responding to the combinaon therapy of ei and pembrolizumab, with 13.5% having a complete response. All responses were durable, with no paents with a response progressing within 9 months. Also encouraging is the strong ORR (40.7%) in the paent subgroup tradionally considered poorly responsive to an-PD-1/PD-L1therapy (PD-L1≥1 group), highlighng potenal of ei to expand ulity of an-PD-1/PD-L1therapy in indicaons that poorly respond to monotherapy. The Phase IIb TACTI-003received fast-trackdesignaon from the US FDA. Recruitment is now open in the US and Ukraine, with further sites expected to open in coming months; primary compleon ancipated H1/2023E.

Expanding clinical development in the Chinese market: Immutep's Chinese partner EOC Pharma, announced plans to iniate a clinical study of ei in combinaon with an an- PD-1therapy in H1/2022E. This new trial builds on EOC's Phase II trial combining ei with chemotherapy in mBC. This is supported by the recent award of a patent in China for use of ei and an-PD-1 an-PD-L1combinaons unl 2036.

Potenal for broad effecve combinaons drives long term value Although immediate focus is on AIPAC mBC and TACTI HNSCC  NSCLC programmes, we see real potenal value from a broad range of ei combinaons across mulple indicaons. Safe and well tolerated, data indicates the drug may find synergy with a broad range of drugs with different MoAs such as CCL2 inhibitors which modulate monocytes.

COMPANY DESCRIPTION

Immutep (known as Prima BioMed unl November 2017) is an Australian clinical-stage biotechnology company that develops immunotherapies for cancer and autoimmune diseases. Immutep is the global leader in the understanding of and in developing therapeucs that modulate Lymphocyte Acvaon Gene-3("LAG-3").LAG-3 was discovered in 1990 at the Instut Gustave Roussy by Dr Frédéric Triebel, Immutep's Chief Scienfic Officer and Chief Medical Officer. The company has three assets in clinical and one asset in preclinical development. The lead product candidate is eilagimod alpha ("ei"), a first-in- class angen presenng cell ("APC") acvator being invesgated in combinaon with chemotherapy or immune therapy for advanced breast cancer and melanoma. Immutep is dual-listed on the Australian Stock Exchange ("IMM") and on the NASDAQ Global Market ("IMMP") in the US (American Depository Receipts), and has operaons in Europe, Australia, and the US. The company has licensing deals with Novars, GSK and EOC (China only), and clinical trial collaboraon and supply agreements with Merck & Co. and Merck KGaA  Pfizer, the laer for lead asset ei.

product candidates; many acve clinical trials with readouts expected 2022E; strong performance of ei alongside many FDA-approved therapies; established collaboraons with big players (Merck (MSD), Merck KGaA  Pfizer, Novars and GSK).

Weaknesses: Sales growth in China dependent on EOC Pharma collaboraon; single asset (ei) accounts for most of value and does not have strong efficacy data as a monotherapy; expired composion of maer patent means ei is only protected by use and formulaon patents.

Opportunies: Provide a novel class of immunotherapy for use alongside many exisng approved therapies across many cancer and auto-immune indicaons; ei may become the first immunotherapy licensed for use in MBC; M&A acvity in the immune-oncology space.

Threats: Market entry by competors and alternave therapies may erode sales; EMA and FDA approval for immune-oncology drugs subject to stringent criteria

Immutep is developing immunotherapies for cancer, with a focus on the immune checkpoint LAG-3. The immune checkpoint inhibitor ("ICI") class has experienced rapid adopon since the launch of BMS's Yervoy (ipilimumab) in 2011, owing to their ability to elicit durable responses in 20 - 50% of paents for up to 10 years. The global ICI market was worth $16.8bn in 2018 and is expected to nearly triple by 2022E, driven largely by expanding use of exisng therapies both in approved and new indicaons. The race is on to develop novel compounds with complementary mechanisms of acon for combinaon therapy able to augment response rate without increasing toxicity, which, if successful, are expected to enjoy rapid uptake.
