The first-in-human Phase 1 trial is a dose escalation study of BI-1607 combined with trastuzumab in HER2+ advanced or metastatic solid tumors. The selected dose of BI-1607 will be studied in a subsequent Phase 2a part of the trial along with trastuzumab in advanced breast, metastatic gastric and gastroesophageal junction HER2+ cancers.

The first patient has been recruited to the Phase 1 part of the study which is expected to recruit between 12 and 26 subjects. The Phase 2a aims to recruit 30 patients in two cohorts of 15 subjects each (one cohort in breast and one in gastric and gastroesophageal cancers). The study will be carried out at 7-12 sites in Spain, the UK, Germany, and in the U.S.

"This new study with our exciting anti-FcyRIIB antibody BI-1607 marks BioInvent’s fifth clinical trial, with four distinct drug candidates, and it is a further demonstration of the productivity of our technology platform. Preclinical data have shown that a BI-1607 surrogate antibody enhances the therapeutic efficacy of anti-HER2 antibodies, and we look forward to further investigating this effect in human subjects," said Martin Welschof, CEO of BioInvent.

Like BI-1206, BioInvent’s lead FcyRIIB antibody, BI-1607 is intended to enhance the efficacy and overcome resistance to existing cancer treatments such as trastuzumab. Trastuzumab alone or in combination with chemotherapy significantly improves overall survival of HER2+ breast cancer patients. However, many patients remain uncured and develop resistance to trastuzumab resulting in relapse or progression of the disease. BI-1607 differs from BI-1206 in that BI-1607 has been engineered for reduced Fc-binding to FcyRs. This alteration generates a major differentiating factor between the two antibodies, and specifically with respect to the best combination partners.

Preclinical data presented at this year’s AACR (Free AACR Whitepaper), indicate that treatment with BI-1607 enhances the efficacy of current anti-HER2 regimens such as trastuzumab. HER2 is a driver of tumor formation and growth in approximately 20% of breast cancers, the most common cancer worldwide in women, and in gastric and gastroesophageal junction adenocarcinoma.

Immutep Reports New Positive Interim Data from its Phase II Study of LAG-3 Candidate, Eftilagimod Alpha, in 2nd line PD-X refractory NSCLC

On August 1, 2022 Immutep Limited (ASX: IMM; NASDAQ: IMMP) ("Immutep" or "the Company"), a biotechnology company developing novel LAG-3-related immunotherapy treatments for cancer and autoimmune disease, reported that new interim data from 2nd line NSCLC patients (Part B) in the Phase II TACTI-002 trial (Press release, Immutep, AUG 1, 2022, View Source [SID1234617244]). The data was presented as part of the electronic poster presentation at the IASLC 2022 World Conference on Lung Cancer (WCLC 2022) being held in Vienna, Austria and is also available on the Company’s website.

This part of TACTI-002 (Part B), evaluates Immutep’s lead product candidate, eftilagimod alpha ("efti" or "IMP321") in combination with MSD’s KEYTRUDA (pembrolizumab) in a total of 36 patients with 2nd line PD-X refractory metastatic NSCLC who were not pre-selected for their PD-L1 status. The data cut-off date is 1 July 2022.

In this 2nd line setting, patients were treated with pembrolizumab, which is an anti-PD-1 therapy, in combination with efti despite having confirmed disease progression on PD-X based therapy in the 1st line setting.3 This was to evaluate whether efti with its unique mechanism of action in combination with pembrolizumab might provide a benefit for these patients that would otherwise move on to chemotherapy in 2nd line. Typically this standard of care 2nd line chemotherapy would be just single agent taxane chemotherapy, as the majority of patients received platinum based doublet chemotherapy plus PD-X therapy in the 1st line setting.

Thus, the enrolled patients were advanced in their disease with limited treatment options.

Immutep CSO and CMO, Dr Frederic Triebel, said: "It is encouraging to see efti in combination with pembrolizumab continues to report promising antitumour and safety results in 2nd line NSCLC. In particular, efti in combination with pembrolizumab is demonstrating sustained survival compared with standard of care chemotherapy regimens, and favourable safety and tolerability. Of course, for patients with such advanced disease, having a chemo-free alternative could mean a very real difference to their quality of life."

"Furthermore, these results provide promising insights into how efti may provide a meaningful patient benefit in other PD-X refractory indications in the future," he said.

TACTI-002 Investigator, Dr Martin Forster of the UCL Cancer Institute and University College London Hospital NHS Foundation, London, UK, said: "The TACTI-002 trial is showing 36.5% of patients have survived for at least 18 months when receiving efti in combination with pembrolizumab. The median overall survival is 9.7 months which is a meaningful survival benefit, plus disease control and durability have also continued favourably as the trial has advanced. All these results support further clinical investigation of efti in combination with pembrolizumab in PD-X resistant NSCLC patients."

Condition of Patients
All enrolled patients had confirmed progressive disease on or after standard of care 1st line therapy with PD-X monotherapy (33%) or a combination of PD-X therapy and platinum-based doublet chemotherapy (67%). These patients are therefore resistant to PD-X based therapy and are referred to as "PD-X refractory". Per standard clinical practice, they would otherwise usually go on to single agent chemotherapy if they received combination PD-X therapy and platinum based doublet chemotherapy in 1st line or, alternatively, go on to doublet chemotherapy if they received PD-X monotherapy in 1st line. A vast majority (75%) of enrolled patients had a PD-L1 tumour proportion score (TPS) of < 50%.

Accordingly, the enrolled patients represent a challenging to treat patient population with limited current treatment options.

Key Findings – data cut-off 1 July 2022

Median OS of 9.7 months for those who received chemo-free therapy of efti in combination with pembrolizumab, which is comparable with current standard of care chemotherapy options in this 2nd line setting4
Favourable sustained survival with 36.5% of patients alive at 18 months5
36.1% (13/36) Disease Control Rate (DCR) and disease control (progression free) in 25% of patients at 6 months
Durable responses of 10+ months in 5.6% (2/36) of patients, with both patients continuing in the trial for over 11 months and 24+ months

Safety
Efti in combination with pembrolizumab continues to be safe and well-tolerated, with no new safety signals. Efti’s good safety profile to date compares favourably to standard of care chemotherapy options.

Conclusion
Efti in combination with pembrolizumab is continuing to demonstrate encouraging early signs of antitumour activity in 2nd line confirmed PD-X refractory, NSCLC patients.

About the TACTI-002 Trial
TACTI-002 (Two ACTive Immunotherapies) is being conducted in collaboration with Merck & Co., Inc., Rahway, NJ, USA (known as "MSD" outside the United States and Canada). The study is evaluating the combination of eftilagimod alpha (efti) with MSD’s KEYTRUDA (pembrolizumab) in patients with second line head and neck squamous cell carcinoma or non-small cell lung cancer in first and second line.

The trial is a Phase II, Simon’s two-stage, non-comparative, open-label, single-arm, multicentre clinical study that is taking place in study centres across Australia, Europe, and the US.

Patients participate in one of the following:

• Part A – first line non-small cell lung cancer (NSCLC), PD-X naïve – given the promising results of the first two stages of Part A, an expansion stage with 74 additional patients was commenced in November 2020 to assist with trial design in subsequent late-stage settings
• Part B – second line NSCLC, PD-X refractory
• Part C – second line head and neck squamous cell carcinoma (HNSCC), PD-X naïve

TACTI-002 is an all-comer study in terms of PD-L1 status, a well-known predictive marker for response to pembrolizumab monotherapy especially in NSCLC and HNSCC.

More information about the trial can be found on Immutep’s website or on ClinicalTrials.gov (Identifier: NCT03625323).

Clinical Highlights from FY 2022 and Recent Weeks

Presented early data from Phase 1/2 study of PORT-2 (IMM60) for patients with melanoma and non-small cell lung cancer at the 2022 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting; encouraging preliminary safety profile of PORT-2 was observed. PORT-2 was well tolerated when administered intravenously as a monotherapy at all doses tested, including demonstrating single agent activity in one of the two heavily pre-treated patients treated at the mid dose level. Translational analysis confirms that PORT-2 activates iNKT cells, NK cells and dendritic cells, supporting the mechanism of action to stimulate both the adaptive and innate immune system.
Announced a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI) and Stimunity, S.A.S, an affiliate of Portage, with experience in the preclinical development of Stimulator of Interferon Genes (STING) agonists for cancer immunotherapy and infectious diseases; agreement supports preclinical and potential clinical development of STING agonists and anti-Receptor for Advanced Glycation End products (RAGE) agents, for possible synergy individually or together to enhance the efficacy of cancer vaccines developed in the NCI CCR Vaccine Branch. This CRADA was subsequently amended to include Portage’s newly acquired adenosine assets.
Promising data was presented by Stimunity on STING-activating therapy, PORT-5 (STI-001) at the AACR (Free AACR Whitepaper) 2022 annual meeting; preclinical data shows that PORT-5, a STING agonist, cyclic guanosine monophosphate–adenosine monophosphate (cGAMP) packaged in a virus-like particle (VLP) developed with Stimunity, can be delivered systemically and achieve potent activation of the STING pathway preferentially in dendritic cells.
Announced new collaborations with Stanford University and University of Birmingham; new collaborations include Dr. Carmela De Santo (University of Birmingham) on iNKTs, and Dr. Robert Negrin (Stanford University) to evaluate the use of PORT-2 with iNKT cell therapies in animals.
FY 2022 Financial Results

The Company generated a net loss and comprehensive loss of approximately $19.2 million during the year ended March 31, 2022 ("Fiscal 2022"), compared to a net loss and comprehensive loss of approximately $17.2 million during the year ended March 31, 2021 ("Fiscal 2021"), an increase in loss of $2.0 million year over year.

Operating expenses, which include research and development and general and administrative expenses, were $15.6 million in Fiscal 2022, compared to $12.4 million in Fiscal 2021, an increase of $3.2 million, which is discussed more fully below. Operating expenses included $9.1 million of non-cash share-based compensation expense in Fiscal 2022, compared to $8.8 million in Fiscal 2021.

Research & development ("R&D") costs decreased by approximately $0.5 million, or approximately 7%, from approximately $7.3 million in Fiscal 2021, to approximately $6.8 million in Fiscal 2022. Fiscal 2021 R&D costs were reduced by the receipt of a $0.6 million legal settlement in respect of some product development costs; accordingly, normalized expenses decreased $1.1 million year over year. The decrease was primarily attributable to non-cash share-based compensation expense associated with grants made under the Amended and Restated 2021 Equity Incentive Plan of $0.7 million, a decrease in other non-cash expense of $0.5 million, a decrease of $0.5 million in other R&D costs relating to outside services and a decrease of $0.4 million in other R&D costs relating to services and storage, partially offset by a year over year increase in compensation of $1.0 million for employees/consultants involved in research and development activities.

General and administrative ("G&A") expenses increased by approximately $3.7 million, or approximately 73%, from approximately $5.1 million in Fiscal 2021, to approximately $8.8 million in Fiscal 2022. The principal reason for the increase was the $1.6 million of non-cash share-based compensation expense associated with the Company’s Amended and Restated 2021 Equity Incentive Plan, of which $2.4 million is associated with Directors’ compensation and $0.8 million is associated with the new grants issued in January and February 2022, which was partially offset by a decrease of $1.6 million associated with management compensation and a $0.1 million year over year decrease in other non-cash expense. Additionally, the Company incurred an increase of $1.0 million in professional fees relating to initiatives associated with a corporate restructuring and public relations / business development. Finally, D&O insurance premiums increased $1.4 million in the current year period due to market rate increases in the cost of coverage, partially offset by a decrease in office and general expenses of $0.2 million, attributable to investor related expense.

Additionally, the Company reflected a net deferred income tax expense of $4.4 million in Fiscal 2022, compared to a net deferred income tax expense of $2.3 million in Fiscal 2021. The principal reason for the change was a $7.0 million increase attributable to an increase in the U.K. income tax rate, net of the recognition of $0.7 million of current year losses and $0.8 million of prior year losses and a $1.1 million benefit due to the foreign currency effect on the deferred tax liability balance settleable in Great British pounds. The Fiscal 2021 net deferred income tax expense was attributable to the foreign currency effect on the deferred tax liability balance settleable in Great British pounds, which was partially offset by recoverable research and development tax credits.

As of March 31, 2022, the Company had cash and cash equivalents of approximately $23.4 million and total current liabilities of approximately $0.8 million (inclusive of approximately $0.03 million warrant liability settleable on a non-cash basis). For the year ended March 31, 2022, the Company is reporting a net loss of approximately $19.2 million and cash used in operating activities of approximately $6.8 million.

As of June 30, 2022, the Company had approximately $21.0 million of cash and cash equivalents on hand.
