Purple Biotech Completes Patient Enrollment in Phase 2 Pancreatic Cancer Trial
14 12월 2023 - 8:50PM
Purple Biotech Ltd. ("Purple Biotech" or "the Company")
(NASDAQ/TASE: PPBT), a clinical-stage company developing
first-in-class therapies that harness the power of the tumor
microenvironment to overcome tumor immune evasion and drug
resistance, today announced it has completed patient enrollment in
a Phase 2 study of CM24, a multi-functional immune checkpoint
inhibitor, for the treatment of pancreatic ductal adenocarcinoma
(PDAC).
The Phase 2 study (NCT04731467), in collaboration with Bristol
Myers Squibb (BMS), is evaluating CM24 in combination with BMS’s
nivolumab plus chemotherapy in PDAC patients as a 2nd line
treatment as compared to chemotherapy alone. The primary endpoint
is overall survival (OS). Approximately 60 patients have been
enrolled through 18 centers in the U.S., Spain and Israel.
The trial was fully enrolled in advance of the anticipated 2024
timeline. An interim analysis of overall survival, the primary
endpoint of the study is expected during 1H 2024 and topline
analysis is expected in 2H 2024.
“Having completed patient enrollment, we now look forward to
reporting overall survival results in 2024. We thank the patients
and their families for participating in this important and
promising study, which may advance CM24 toward a pivotal study for
a population in dire need of an effective alternative. Survival
rates in pancreatic cancer are unfortunately very low and with
CM24’s novel CEACAM1 target, we believe we may have a positive
impact on extending survival,” stated Purple Biotech CEO, Gil
Efron.
An estimated 60,000 people are diagnosed with pancreatic cancer
in the U.S. alone with a 5-year survival rate of only 12%. In
patients treated with chemotherapy as a 2nd line treatment,
the 5-year survival drops to 3%.
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 NT219, CM24 and IM1240. NT219
is a dual inhibitor, novel small molecule that simultaneously
targets IRS1/2 and STAT3. In a Phase 1/2 study of NT219, the
Company is currently advancing it in a dose escalation as a
monotherapy treatment of solid tumors, and in a dose escalation in
combination with cetuximab for the treatment of recurrent and
metastatic squamous cell carcinoma of the head and neck (SCCHN) or
colorectal adenocarcinoma (CRC). These studies will be followed by
an expansion phase of NT219 at its recommended Phase 2 level in
combination with cetuximab in patients with recurrent and
metastatic SCCHN. CM24 is a humanized monoclonal antibody that
blocks CEACAM1, an immune checkpoint protein that supports tumor
immune evasion and survival through multiple 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.
IM1240 is a preclinical, conditionally-activated tri-specific
antibody that engages both T cells and NK cells to mount a strong,
localized immune response within the tumor microenvironment. The
third arm specifically targets the Tumor Associated Antigen (TAA)
5T4 that is expressed in a variety of solid tumors and is
correlated with advanced disease, increased invasiveness and poor
clinical outcomes. IM1240 has a cleavable capping technology that
confines the compound's therapeutic activity to the local tumor
microenvironment, and thereby potentially increases the anticipated
therapeutic window in patients. The Company's corporate
headquarters are located in Rehovot, Israel. For more information,

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
difficulty of predicting actions of the U.S. Food and Drug
Administration or any other applicable regulator of pharmaceutical
products; 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
