Exhibit 99.1
Purple Biotech to Present Data for its Tri-Specific
Antibody Platform—CAPTN-3—at the EORTC-NCI-AACR Symposium on Molecular Targets and Cancer Therapeutics
CAPTN-3 is a conditionally activated tri-specific
antibody platform that features novel dual engagement of T cells and NK cells to mount an optimal anti-tumoral immune response against
cancer
REHOVOT, Israel, Oct. 10, 2024 (GLOBE NEWSWIRE) -- Purple Biotech
Ltd. (“Purple Biotech” or “the Company”) (NASDAQ/TASE: PPBT), a clinical-stage company developing first-in-class therapies
that overcome tumor immune evasion and drug resistance, today announced it has been selected for a poster presentation at the 36th
European Organization for Research and Treatment of Cancer, National Cancer Institute, American Association for Cancer Research (EORTC-NCI-AACR)
Symposium on Molecular Targets and Cancer Therapeutics (the “Triple Meeting”) held October 23-25, 2024 in Barcelona, Spain.
Purple Biotech’s poster titled “CAPTN-3:
A novel platform of conditionally activated T cell and NK cell engagers” (Abstract # 450, poster board number: PB438) will be presented
by Dr. Hadas Reuveni, VP R&D of Purple Biotech, during a ‘New therapies in immuno oncology’ poster session on Friday,
25 October 2024.
CAPTN-3 is a First-in-class platform of conditionally
activated tri-specific antibodies engaging both T cells and NK cells with the tumor to create an immune synapse with enhanced anti-tumor
efficacy. The NK engager arm (aNKG2A) of our lead compound also acts as a checkpoint inhibitor
for both NK cells and highly cytotoxic T cell subsets, unleashing both innate and adaptive immune subsets against the tumor.
Purple Biotech’s lead CAPTN-3 platform candidate,
IM1240, targets 5T4 as a tumor associated antigen (TAA), which is overexpressed in a variety of solid tumors and is correlated with advanced
disease, increased invasiveness, and poor clinical outcome. 5T4, also known as trophoblast glycoprotein (TPBG), is an oncofetal surface
protein that is not found on adult healthy tissues but is abnormally expressed in several cancer types. This specific expression pattern
as well as the correlation with poor prognosis in different cancer diseases such as lung, gastric, head and neck and other cancers makes
it an ideal TAA for various therapeutic approaches.
About Purple Biotech
Purple Biotech Ltd. (NASDAQ/TASE: PPBT) is a clinical-stage
company developing first-in-class therapies that seek to overcome tumor immune evasion and drug resistance. The Company’s oncology pipeline
includes CM24, NT219 and IM1240. CM24 is a humanized monoclonal antibody that blocks CEACAM1, that supports tumor immune evasion and survival
through multiple pathways. CEACAM1 on tumor cells, immune cells and neutrophils extracellular traps is a novel target for the treatment
of multiple cancer indications. As a proof of concept of these novel pathways, the Company is advancing CM24 as a combination therapy
with anti-PD-1 checkpoint inhibitors in a Phase 2 study for the treatment of pancreatic ductal adenocarcinoma (PDAC). The Company has
entered into a clinical collaboration agreement with Bristol Myers Squibb for the Phase 2 clinical trials to evaluate the combination
of CM24 with the PD-1 inhibitor nivolumab in addition to chemotherapy. NT219 is a dual inhibitor, novel small molecule that simultaneously
targets IRS1/2 and STAT3. A Phase 1 dose escalation study was concluded as a monotherapy and in combination with cetuximab in which NT219
demonstrated anti-tumor activity in combination with cetuximab in second line patients with recurrent and/or metastatic SCCHN (R/N SCCHN).
The Company is advancing CAPTN-3, a preclinical platform of conditionally-activated tri-specific antibody that engages both T cells and
NK cells to induce a strong, localized immune response within the tumor microenvironment. The cleavable capping technology confines the
compound’s therapeutic activity to the local tumor microenvironment, and thereby potentially increases the anticipated therapeutic window
in patients. The third arm specifically targets the Tumor Associated Antigen (TAA). The technology presents a novel mechanism of action
by unleashing both innate and adaptive immune systems to mount an optimal anti-tumoral immune response. IM1240 is the first tri-specific
antibody in development that targets 5T4 expressed in a variety of solid tumors and is correlated with advanced disease, increased invasiveness
and poor clinical outcomes. The Company’s corporate headquarters are located in Rehovot, Israel. For more information, please visit https://purple-biotech.com/.

or achievements to be significantly different from any future results, performance or achievements expressed or implied by the forward-looking
statements. Important factors that could cause or contribute to such differences include, among others, risks relating to: the plans,
strategies and objectives of management for future operations; product development for NT219, CM24 and IM1240; the process by which such
early stage therapeutic candidates could potentially lead to an approved drug product is long and subject to highly significant risks,
particularly with respect to a joint development collaboration; the fact that drug development and commercialization involves a lengthy
and expensive process with uncertain outcomes; our ability to successfully develop and commercialize our pharmaceutical products; the
expense, length, progress and results of any clinical trials; the impact of any changes in regulation and legislation that could affect
the pharmaceutical industry; the difficulty in receiving the regulatory approvals necessary in order to commercialize our products; the

the regulatory environment and changes in the health policies and regimes in the countries in which we operate; the uncertainty surrounding
the actual market reception to our pharmaceutical products once cleared for marketing in a particular market; the introduction of competing
products; patents obtained by competitors; dependence on the effectiveness of our patents and other protections for innovative products;
our ability to obtain, maintain and defend issued patents; the commencement of any patent interference or infringement action against
our patents, and our ability to prevail, obtain a favorable decision or recover damages in any such action; and the exposure to litigation,
