CIS Biopharma AG recently presented an antibody-drug conjugate (ADC) targeting the L1 cell adhesion molecule (L1CAM/CD171) as a potential candidate for the treatment of advanced tumors.
Deoxyhypusine synthase (DHPS), which activates the eukaryotic translation initiation factor 5A, shows potential as a therapeutic target against melanoma, which is quite aggressive and prone to metastasize. It is highly expressed in tumors but not in healthy tissues.
Convalife Pharmaceuticals Co. Ltd. has presented data for their bispecific antibody CVL-006, which targets both PD-1 and VEGF-A. CVL-006 blocks both the PD-1-driven immune pathway plus VEGF-A-driven angiogenesis, thus conferring a dual mechanism for superior antitumoral activity.
While immunotherapy targeting PD-1 or its ligand PD-L1 has transformed cancer treatment by overcoming T-cell exhaustion, only a minority of patients achieves durable responses after treatment.
Oncolytic viruses are being actively explored as cancer therapies because they preferentially infect tumor cells and cause their lysis. At the same time, the viruses can accommodate transgenes that can stimulate anti-cancer responses in the local tumor microenvironment.
Researchers continue to search for how they can inhibit cancer metastasis as it can severely worsen prognosis, even if the primary tumor responded well to therapy. Researchers at Università degli Studi di Torino and collaborators previously showed that injecting an RNA aptamer targeting the miRNA miR-214, called anti-miR-214 sponge, reduced metastasis of tumors to lungs and liver. One drawback of this potential therapeutic approach was that the inhibitor oligo could enter all cells, not only tumors.
IO Biotech ApS will discuss this fall with the U.S. FDA the data package related to Cylembio (imsapepimut and etimupepimut, adjuvanted) after the off-the-shelf therapeutic cancer vaccine prospect missed “by a hair” the primary endpoint in a pivotal phase III melanoma trial, said CEO Mai-Britt Zocca.
Melanoma is one of the most mutation-prone cancers, with 90% of cases involving the V600E mutation in BRAF kinase. Several therapies are available against melanoma, but each one is associated with substantial drawbacks. Researchers at Shanghai Institute of Materia Medica of the Chinese Academy of Sciences and collaborators reasoned that it might be effective to simultaneously inhibit both angiogenesis and immunosuppression in the tumor microenvironment.
Researchers at Servizo Galego de Saude and Universidade de Santiago de Compostela have described senolytic compounds reported to be useful for the treatment of cancer, metabolic diseases, and neurological, dermatological, cardiovascular, eye, renal and inflammatory disorders.
A newly developed oncolytic virus, SKV-012, has demonstrated promising results in preclinical studies and a phase I clinical trial for the treatment of advanced solid tumors.
