- First patient in Cohort four has been treated with
TTX-MC138
- Ten patients have been treated with TTX-MC138 at escalating
dose levels
- Additional patients being evaluated for eligibility for
expanded enrollment
- No significant safety or dose limiting toxicities have been
reported
BOSTON, March 27,
2025 /PRNewswire/ -- TransCode Therapeutics, Inc.
(NASDAQ: RNAZ), the RNA oncology company committed to more
effectively treating cancer using RNA therapeutics, today announced
that the first patient in Cohort 4 of its Phase I clinical trial
has received their initial dose. TransCode also reported that
two additional patients in Cohort 4 are scheduled to receive
TTX-MC138. The therapeutic candidate being evaluated, TTX-MC138, is
TransCode's lead candidate designed to inhibit microRNA-10b, a
microRNA critical to the emergence and progression of metastatic
cancer. No significant safety or dose limiting
toxicities have been reported. The dose administered to the
fourth cohort, as originally planned in the clinical protocol, is
approximately fifty percent higher than the dose administered in
the third cohort.
Under the clinical protocol, patients may remain on study absent
safety events or disease progression. Of the ten patients treated
with TTX-MC138 in the first four cohorts, seven remain on study for
continued treatment as there have been no dose limiting toxicities
or disease progression in these patients. In addition to approving
opening the fourth cohort, the Safety Review Committee approved
enrollment of additional patients in Cohort 3 to build upon the
safety profile of TTX-MC138. Further, data analysis of both
pharmacokinetic (PK) and pharmacodynamic (PD) activity from Cohorts
1, 2 and 3 is ongoing and suggests that TTX-MC138 demonstrates a
PK/PD profile consistent with preclinical results and results from
TransCode's Phase 0 clinical trial.
"Commencement of treatment in Cohort 4 has been our vision for
evaluating the potential of TTX-MC138 at multiple dose levels.
Cohort 4 builds upon our safety, PK/PD and exploratory data and is
an important element of our clinical development strategy. We
believe this milestone will inform the dose expansion stage of the
clinical trial and may allow us to obtain initial evidence of
clinical activity as the program continues to advance," commented
Sue Duggan, TransCode's Senior Vice President of Operations.
Duggan added, "Enrollment into the study continues based on the
cumulative safety data review. Additional Cohort 4 patients are
scheduled for treatment in Cohort 4 for treatment with TTX-MC138
while preliminary data analysis
continues."
About TTX-MC138
TTX-MC138 is a first-in-class therapeutic candidate that targets
microRNA-10b, a micro-RNA widely believed to be a driver of
metastatic disease. TransCode's 2023 Phase 0 clinical trial
produced evidence of delivery of a radiolabeled version of
TTX-MC138 to metastatic lesions and pharmacodynamic activity, even
at a microdose of the drug candidate, suggesting a broad
therapeutic window for TTX-MC138.
About the Trial
TransCode's Phase 1 clinical trial is a multicenter, open-label,
dose-escalation and dose-expansion study, designed to generate
critical data to support evaluation of the safety and tolerability
of TTX-MC138 in patients with a variety of metastatic solid
cancers. While not an endpoint, the trial may provide early
evidence of clinical activity of TTX-MC138. The trial comprises an
initial dose-escalation phase followed by a dose-expansion phase.
The primary objective of the dose-escalation phase is to evaluate
the safety and tolerability of escalating dose levels of TTX-MC138.
In the dose-expansion phase, the safety, tolerability and
anti-tumor activity of TTX-MC138 will be further evaluated in
certain tumor types selected based on preliminary results from the
dose-escalation phase.
