LMP744 treats gliomas, readily crossing the blood brain barrier (BBB) at 10 times the concentration required to kill cancer cells and sustains a high concentration for over 24 hours per dose.

"For decades glioblastoma brain cancer patients have not seen appreciable increases in overall survival rates with Temodar, the current standard of care treatment," said Mr. Randall Riggs, President & CEO of Gibson Oncology. "Our goal is to advance both LMP400 and LMP744 to market via the shortest and quickest path, thus benefiting cancer patients in need."

Obtaining ODD for LMP744 for all gliomas underscores the promising and novel treatment of the drug to inhibit two cancer targets: TOPO 1 and downregulate cMyc overexpression through the drug’s potent binding of the G4 quadruplex of cMyc.

"This crucial designation could not come at a more critical time for the families who are fighting this disease," said Dr. Kush Dhody, President, Amarex. "Reaching this milestone sets the company up for future success and, most importantly, poises Gibson Oncology to continue its path to commercialization of this life-saving treatment."

Through a multi-year collaboration with cMyc expert, Dr. Danzhou Yang of Purdue University, Gibson Oncology discovered that LMP400, which received ODD earlier in the year, and LMP744 are potent nM inhibitors of both TOPO 1 and cMyc oncogene. Together, the teams determined that LMP744, a small molecule, selectively targets two well-known drivers of human cancers, cMyc oncogene and TOPO 1.

The discovery of this compound’s unique anti-cancer mechanism of action (MOA) allowed Gibson Oncology to better position LMP744 and LMP400 to cancer targets with high unmet medical needs.

Presently, LMP744 and LMP400 is positioned to enter a Phase 2 human clinical trial in recurrent gliomas in collaboration with the National Institutes of Health (NIH).

Gibson Oncology believes it is important to leverage the Orphan Drug Designation both drugs have received from the FDA for all gliomas, not just glioblastomas, which includes children with gliomas. Rapid regulatory advancement empowers LMP400 and LMP744 to the shortest and quickest path to market, thus benefiting cancer patients in need.

On September 24, 2024 Duke Street Bio Ltd, a precision medicine biotech developing next generation small molecule cancer therapies, reported that the European Medicines Agency (EMA) has granted approval to commence a clinical trial for its highly-selective PARP1 inhibitor, DSB2455 (Press release, Duke Street Bio, SEP 24, 2024, View Source [SID1234646835]). This potentially best-in-class, potent, highly selective and CNS-penetrant agent targets cancers that harbour homologous recombination deficiencies (HRD) including BRCA mutations. The safety profile of first generation non-selective PARP1/2 inhibitors has restricted their application, particularly in combination with chemotherapy and radiotherapy. By selectively inhibiting PARP1, we believe that DSB2455 has the potential to achieve a significantly enhanced therapeutic index, representing a significant advancement in precision medicine cancer treatment. Preliminary data indicate a strong safety profile and compelling efficacy in preclinical studies, paving the way to open our trial in the clinic.

Alan Wise, CEO of Duke Street Bio, commented, "The approval of the DSB2455 First-in-Human clinical trial by the EMA is a testament to the therapeutic potential of our innovative approach in the DDR space. Duke Street Bio’s mission is to improve patient outcomes and bring new hope to individuals battling cancer. We believe that DSB2455 has the potential for improved efficacy and tolerability versus first-generation PARP inhibitors in patient populations where there is still significant unmet medical need."

Indication and Important Safety Information About POSLUMA

INDICATION

POSLUMA (flotufolastat F 18) injection is indicated for positron emission tomography (PET) of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer

with suspected metastasis who are candidates for initial definitive therapy
with suspected recurrence based on elevated serum prostate-specific antigen (PSA) level
IMPORTANT SAFETY INFORMATION

Image interpretation errors can occur with POSLUMA PET. A negative image does not rule out the presence of prostate cancer and a positive image does not confirm the presence of prostate cancer. The performance of POSLUMA for imaging metastatic pelvic lymph nodes in patients prior to initial definitive therapy seems to be affected by serum PSA levels and risk grouping. The performance of POSLUMA for imaging patients with biochemical evidence of recurrence of prostate cancer seems to be affected by serum PSA levels. Flotufolastat F 18 uptake is not specific for prostate cancer and may occur in other types of cancer, in non-malignant processes, and in normal tissues. Clinical correlation, which may include histopathological evaluation, is recommended.
Risk of Image Misinterpretation in Patients with Suspected Prostate Cancer Recurrence: The interpretation of POSLUMA PET may differ depending on imaging readers, particularly in the prostate/prostate bed region. Because of the associated risk of false positive interpretation, consider multidisciplinary consultation and histopathological confirmation when clinical decision-making hinges on flotufolastat F 18 uptake only in the prostate/prostate bed region or only on uptake interpreted as borderline.
POSLUMA use contributes to a patient’s overall long-term cumulative radiation exposure. Long-term cumulative radiation exposure is associated with an increased risk for cancer. Advise patients to hydrate before and after administration and to void frequently after administration. Ensure safe handling to minimize radiation exposure to the patient and health care providers.
The adverse reactions reported in ≥0.4% of patients in clinical studies were diarrhea, blood pressure increase and injection site pain.
Drug Interactions: androgen deprivation therapy (ADT) and other therapies targeting the androgen pathway, such as androgen receptor antagonists, may result in changes in uptake of flotufolastat F 18 in prostate cancer. The effect of these therapies on performance of POSLUMA PET has not been established.
To report suspected adverse reactions to POSLUMA, call 1-844-POSLUMA (1-844-767-5862) or contact FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

This approval is based on data such as the results of a multicenter, open-label, single-arm clinical phase II trial (Study 201) conducted by Eisai in Japan and China. Study 201 enrolled 63 patients with unresectable advanced or metastatic cholangiocarcinoma with FGFR2 gene fusions or rearrangements previously treated with gemcitabine-based combination chemotherapy. The primary endpoint of this study was objective response rate (ORR), and secondary endpoints included safety.1 This study achieved its primary endpoint and exceeded a prespecified tumor response threshold (15%) with statistical significance: ORR of patients treated with TASFYGO was 30.2% (90% confidence interval (CI): 20.7-41.0) as assessed by independent imaging review. Treatment-emergent adverse events (incidence of 25% or more) observed in this study were hyperphosphataemia (81.0%), palmar-plantar erythrodysaesthesia syndrome (44.4%), diarrhoea (36.5%), aspartate aminotransferase increase (31.7%), alanine aminotransferase increase (28.6%) and stomatitis (25.4%).

The estimated number of patients in Japan with biliary tract cancer is approximately 22,0002,3 with approximately 25% of the five-year relative survival rate,2 making it an intractable cancer with the second worst prognosis following pancreatic cancer. Since drug therapy options are limited in comparison with other cancers, it is a disease with significant unmet medical needs. FGFR2 gene fusions or rearrangements are observed in approximately 14% of intrahepatic cholangiocarcinoma, which accounts for 15-30% of biliary tract cancers.4 FGFR genetic aberrations such as the gene fusions are known to be deeply involved in the proliferation, survival and migration of cancer cells as well as tumor angiogenesis and drug resistance. As these genetic aberrations in FGFRs have been observed in various other types of cancers as well as biliary tract cancer, there is growing interest in FGFRs as a promising target for cancer therapy. TASFYGO is thought to show tumor growth inhibition by selectively inhibiting FGFR1, 2 and 3, and blocking those signals.5,6 In non-clinical studies, the antitumor activity of TASFYGO was confirmed in cells expressing the FGFR2-fusion genes, which were identified by the National Cancer Center Japan (Headquarters: Tokyo) through large-scale genomic analysis of Japanese biliary tract cancer. The companion diagnostic test to detect FGFR2 gene fusions or rearrangements for the use of TASFYGO in biliary tract cancer, "AmoyDx FGFR2 Break-apart FISH Probe Kit" by Nihon Stery, Inc. (Headquarters: Tokyo) was approved in August 2024.7

Eisai aims to make continuous efforts to meet the diversified needs of and increase the benefits provided to patients with cancer, their families, and healthcare professionals, by delivering TASFYGO as a new treatment option for biliary tract cancer with FGFR2 gene fusions or rearrangements.
