NuCana Presents Encouraging Data on NUC-7738 in Combination with Pembrolizumab in PD-1 Inhibitor Refractory and Resistant Melanoma Patients at the ESMO Congress 2024
Source: GlobeNewswire Inc.
NuCana plc (NASDAQ: NCNA) presented final data from the Phase 2 NuTide:701 study at the ESMO Congress on NUC-7738 in combination with pembrolizumab for patients with metastatic melanoma who were refractory to or had relapsed on prior PD-1 inhibitor therapy.
In this cohort of 12 patients, most of whom had received at least two prior lines of PD-1 inhibitor therapy, nine (75%) achieved disease control, including two patients who achieved Partial Responses. One of these patients, who had received two prior lines of PD-1 inhibitor-based therapy and had progressed on their latest treatment of ipilimumab plus nivolumab within two months, achieved a 55% reduction in tumor volume. Seven of the 12 patients had a progression free survival time of greater than five months, which is highly atypical in this patient population. In addition to achieving these encouraging efficacy signals, the combination of NUC-7738 and pembrolizumab had a favorable safety profile.
NUC-7738βs ability to sensitize PD-1 resistant tumors to rechallenge with PD-1 inhibitors is believed to be due to its ability to target multiple aspects of the tumor microenvironment (TME) via the disruption of RNA polyadenylation and subsequent changes to gene expression in cancer cells. In support of this hypothesis, data presented from tumor biopsies obtained before and after NUC-7738 based treatment demonstrated increases in genes related to antigen presentation and T-cell activation.
Hugh S. Griffith, NuCanaβs Founder and Chief Executive Officer said: βWe are very excited to share these data on NUC-7738 in combination with pembrolizumab in PD-1 inhibitor refractory and resistant patients with melanoma. Outcomes in this patient population are very poor, with median progression free survival of 2-3 months with the current standard of care, so we are very encouraged that the majority of patients who received this combination achieved a progression free survival of more than five months.β
Mr. Griffith continued: βThe translational data that has been generated in this study and in previous non-clinical studies give us confidence that the effects we are seeing are a result of NUC-7738 making previously resistant tumors sensitive to rechallenge with PD-1 inhibitors by targeting multiple aspects of the tumor microenvironment. Our data on NUC-7738 obtained in other tumor types indicate that this phenomenon is not restricted to melanoma and that NUC-7738 may have the ability to sensitize other PD-1 inhibitor resistant tumor types. We look forward to sharing our development plans for NUC-7738 in the near future.β
About NuCana
NuCana is a clinical-stage biopharmaceutical company focused on significantly improving treatment outcomes for patients with cancer by applying our ProTide technology to transform some of the most widely prescribed chemotherapy agents, nucleoside analogs, into more effective and safer medicines. While these conventional agents remain part of the standard of care for the treatment of many solid and hematological tumors, they have significant shortcomings that limit their efficacy and they are often poorly tolerated. Utilizing our proprietary technology, we are developing new medicines, ProTides, designed to overcome the key limitations of nucleoside analogs and generate much higher concentrations of anti-cancer metabolites in cancer cells. NuCanaβs pipeline includes NUC-3373 and NUC-7738. NUC-3373 is a new chemical entity derived from the nucleoside analog 5-fluorouracil, a widely used chemotherapy agent. NUC-3373 is currently being evaluated in two ongoing clinical studies: a Phase 1b/2 study (NuTide:302) in combination with leucovorin, irinotecan or oxaliplatin, and bevacizumab in patients with metastatic colorectal cancer; and a Phase 1b/2 modular study (NuTide:303) of NUC-3373 in combination with the PD-1 inhibitor pembrolizumab for patients with advanced solid tumors and in combination with docetaxel for patients with lung cancer. NUC-7738 is a novel anti-cancer agent that disrupts RNA polyadenylation, profoundly impacts gene expression in cancer cells and targets multiple aspects of the tumor microenvironment. NUC-7738 is in the Phase 2 part of a Phase 1/2 study (NuTide:701) which is evaluating NUC-7738 as a monotherapy in patients with advanced solid tumors and in combination with pembrolizumab in patients with melanoma.

NCNA: Great DD, too!!! Boy, I got SUCKERED!! (But, I'll only cry just a few more hours --- see me, live, below!!)
"Yeah, sure!!! And I myself just got a Patent to kill CANCER too!!! I grow the Cancer cells in a Petri Dish, then toss ARCO-PREMIUM-TOP-TIER-GASOLINE on it, and hit it with my Bic CIGARETTE LIGHTER!!! Works every time!!!"

NCNA: CONGRATS, Dude!!! You worked it as a PRO would!!! (I worked it like a FOOL!!! Dumped all awhile back, at a LOSS!! Good thing I did NOT 'toss-the-farm' at it!!) And indeed, just like you too emphasized, any OTHER firm would have HYPED-the-fluck out of any kind of Cancer-related Patent, but this firm did NOTHING.)
CONGRATS again!!!

NCNA: Most worrisome here --- via my own stupid, belated hindsight --- was that there was NO Company PR, nor otherwise "NEWS", about their own new PATENT. THAT is really, really, really, WORRISOME!!!!
