25 Outubro 2023 - 9:15AM
Panbela Therapeutics, Inc. (Nasdaq: PBLA), a clinical stage company
developing disruptive therapeutics for the treatment of patients
with urgent unmet medical needs, today announced that an abstract
about SBP-101 and CPP-1X (also known as DFMO or Eflornithine)
research in multiple myeloma (cell lines), has been accepted for an
online publication on the American Society of Hematology (ASH)
meeting site in the November supplemental issue of the journal
Blood.
The work reflects the company’s on-going collaboration with
researchers from The University of Texas MD Anderson Cancer Center
and will become part of the permanent ASH and Blood abstracts
archive.
- Additional meeting information can be found on the ASH website:
https://www.hematology.org/meetings/annual-meeting/abstracts
- The abstract will
also be available on the company's website
at https://panbela.com/events-presentations/
once the information has been released by ASH.
About Panbela’s PipelineThe pipeline
consists of assets currently in clinical trials with an initial
focus on familial adenomatous polyposis (FAP), first-line
metastatic pancreatic cancer, neoadjuvant pancreatic cancer,
colorectal cancer prevention and ovarian cancer. The combined
development programs have a steady cadence of anticipated catalysts
with programs ranging from pre-clinical to registration
studies.
Ivospemin (SBP-101)Ivospemin is a
proprietary polyamine analogue designed to induce polyamine
metabolic inhibition (PMI) by exploiting an observed high affinity
of the compound for pancreatic ductal adenocarcinoma and other
tumors. It has shown signals of tumor growth inhibition in clinical
studies of metastatic pancreatic cancer patients, demonstrating a
median overall survival (OS) of 14.6 months and an objective
response rate (ORR) of 48%, both exceeding what is typical for the
standard of care of gemcitabine + nab-paclitaxel suggesting
potential complementary activity with the existing FDA-approved
standard chemotherapy regimen. In data evaluated from clinical
studies to date, ivospemin has not shown exacerbation of bone
marrow suppression and peripheral neuropathy, which can be
chemotherapy-related adverse events. Serious visual adverse events
have been evaluated and patients with a history of retinopathy or
at risk of retinal detachment will be excluded from future SBP-101
studies. The safety data and PMI profile observed in the previous
Panbela-sponsored clinical trials provide support for continued
evaluation of ivospemin in the ASPIRE trial.
Flynpovi ™Flynpovi is a combination of
CPP-1X (eflornithine) and sulindac with a dual mechanism inhibiting
polyamine synthesis and increasing polyamine export and catabolism.
In a Phase 3 clinical trial in patients with sporadic large bowel
polyps, the combination prevented > 90% subsequent pre-cancerous
sporadic adenomas versus placebo. Focusing on FAP patients with
lower gastrointestinal tract anatomy in the recent Phase 3 trial
comparing Flynpovi to single agent eflornithine and single agent
sulindac, FAP patients with lower GI anatomy (patients with an
intact colon, retained rectum or surgical pouch), showed
statistically significant benefit compared to both single agents
(p≤0.02) in delaying surgical events in the lower GI for up to four
years. The safety profile for Flynpovi did not significantly differ
from the single agents and supports the continued evaluation of
Flynpovi for FAP.
CPP-1XCPP-1X (eflornithine) is being developed
as a single agent tablet or high dose powder sachet for several
indications including prevention of gastric cancer, treatment of
neuroblastoma and recent onset Type 1 diabetes. Preclinical studies
as well as Phase 1 or Phase 2 investigator-initiated trials suggest
that CPP-1X treatment may be well-tolerated and has potential
activity.
