Reassessing vascular endothelial growth factor (VEGF) in anti-angiogenic cancer therapy

Review

作者: Ojo, Oluwafemi Adeleke ; Iyobhebhe, Matthew ; Maimako, Rotdelmwa Filibus ; Elebiyo, Tobiloba C ; Evbuomwan, Ikponmwosa O ; Adeyemi, Oluyomi S ; Oluba, Olarewaju M ; Rotimi, Damilare

Vascularization is fundamental to the growth and spread of tumor cells to distant sites. As a consequence, angiogenesis, the sprouting of new blood vessels from existing ones, is a characteristic trait of cancer. In 1971, Judah Folkman postulated that tumour growth is angiogenesis dependent and that by cutting off blood supply, a neoplastic lesion could be potentially starved into remission. Decades of research have been devoted to understanding the role that vascular endothelial growth factor (VEGF) plays in tumor angiogenesis, and it has been identified as a significant pro-angiogenic factor that is frequently overexpressed within a tumor mass. Today, anti-VEGF drugs such as Sunitinib, Sorafenib, Axitinib, Tanibirumab, and Ramucirumab have been approved for the treatment of advanced and metastatic cancers. However, anti-angiogenic therapy has turned out to be more complex than originally thought. The failure of this therapeutic option calls for a reevaluation of VEGF as the major target in anti-angiogenic cancer therapy. The call for reassessment is based on two rationales: first, tumour blood vessels are abnormal, disorganized, and leaky; this not only prevents optimal drug delivery but it also promotes hypoxia and metastasis; secondly, tumour growth or regrowth might be blood vessel dependent and not angiogenesis dependent as tumour cells can acquire blood vessels via non-angiogenic mechanisms. Therefore, a critical assessment of VEGF, VEGFRs, and their inhibitors could glean newer options such as repurposing anti-VEGF drugs as vascular normalizing agents to enhance drug delivery of immune checkpoint inhibitors.

Monoclonal antibody (mAb) drugs are clinically important for the treatment of various diseases. TTAC-0001 is under development as a new anti-cancer antibody drug targeting VEGFR-2. As the less severe toxicity of TTAC-0001 compared to Bevacizumab, likely due to the decreased in vivo half-life, seems to be related to its structural flexibility, it is important to map the exact flexible regions. Although the ¹³C/¹⁵N-labeled protein is required for NMR analyses, it is difficult to obtain antibody fragments (Fab and scFv) containing disulfide bonds through general cytosolic expression in Escherichia coli (E. coli). Here, we notably increased the periplasmic expression of the ¹³C/¹⁵N-labeled TTAC-0001-Fab (¹³C/¹⁵N-TTAC-Fab) through simple isopropyl β-D-1-thiogalactopyranoside (IPTG)-induction at an increased optical density (1.5 OD_600nm). Through NMR triple resonance experiments, two loop insertions (LI-1 between the V_H and C_H1; LI-2 between the V_L and C_L) were confirmed to be highly flexible. The additional LIs could be another way to engineer the antibody by changing the pharmacokinetic properties.

Summary:

Background Tanibirumab is a fully human monoclonal antibody to vascular endothelial growth factor receptor 2 (VEGFR-2). We conducted a first-in-human phase I study of tanibirumab in patients with solid tumors refractory to standard chemotherapy. Primary endpoints were evaluating safety, pharmacokinetics (PKs), estimating maximum-tolerated dose (MTD) and recommended phase II dose (RP2D). Methods We designed our study to escalate tanibirumab at 9 different dose levels with a 3 + 3 method and tanibirumab (1–28 mg/kg) was administered intravenously on D1, 8, 15 in 28-day courses. Dose limiting toxicities (DLTs) were only assessed during the first cycle of treatment and response evaluation was performed every 2 cycles. The effects of tanibirumab on several angiogenic factors were analyzed. Results From October 2011 to September 2013, a total of 26 patients with refractory solid tumors were enrolled. The median age was 58 years (range, 27–75) and 20 patients were male. The most common tumor type was colorectal cancer (N = 19) and seven patients had a history of previous bevacizumab treatment. As hemangioma continued to occur, the final dose level, 28 mg/kg, was not performed. DLTs were not found, and the MTD was confirmed to be 24 mg/kg. Hemangioma was observed in 16 patients (61.5%), but all were grade 1–2 and disappeared after discontinuation of the study drug. Among the 18 patients in the efficacy set, no objective response was observed, but 11 patients showed stable disease. PKs were characterized by dose-dependent linear exposure and the mean trough concentrations exceeded biologically relevant target levels at 12 mg/kg and above. Serum VEGF, soluble VEGFR-2, and PlGF increased at the 4 mg/kg dose level and above. Conclusions Treatment with tanibirumab showed a tolerable toxicity profile and modest clinical efficacy in patients with refractory solid tumors. A phase II trial of tanibirumab is ongoing now.

PharmAbcine Announces Safety Approval for 4mg Single-dose Cohort in Phase 1 Clinical Trial of PMC-403 for Neovascular Age-related Macular Degeneration

Safety Review Committee (SRC) approves single ascending dose 4mg cohort in Phase 1 trial of PMC-403, preparing for multiple ascending dose 4 mg cohort. PMC-403 is being explored in broader therapeutic areas, including rare vascular disease systemic capillary leak syndrome (SCLS) and kidney diseases. DAEJEON, South Korea, Oct. 14, 2024 /PRNewswire/ -- PharmAbcine, Inc. (KOSDAQ: 208340), a clinical-stage public company developing next-generation therapeutics to address unmet medical needs, today announced that its TIE2-activating antibody candidate, PMC-403, has received unanimous safety approval from the Safety Review Committee (SRC) for the 4mg single ascending dose (SAD) cohort in its Phase 1 clinical trial for neovascular age-related macular degeneration (nAMD). The Company is now preparing to begin enrollment for the 4mg multiple ascending dose (MAD) cohort. PMC-403 is a novel TIE2-activating antibody with a unique mechanism that stabilizes pathological, leaky blood vessels. TIE2 receptors, expressed on endothelial cells, play a critical role in vessel normalization processes such as angiogenesis and intercellular adhesion, thereby inhibiting the progression of AMD. This Phase 1 trial targets patients with neovascular AMD who no longer respond to anti-VEGF standard therapies. The safety and tolerability of the 4mg single dose were successfully confirmed, laying the groundwork for advancing to the multiple-dosing phase. Dr. Weon Sup Lee, Head of R&D and Chief Technology Officer at PharmAbcine, stated, "The successful completion of the 4mg single-dose study is a significant milestone, highlighting the potential of PMC-403 as a breakthrough treatment for AMD. As we move forward with the multiple-dose study, we aim to gather additional safety and efficacy data to establish a robust foundation for Phase 2 trials." Macular degeneration, a leading cause of blindness, results from aging-related damage to the retina, particularly due to the development of abnormal blood vessels in the macula. The global aging population has led to a rapid increase in cases, and current treatments with anti-VEGF inhibitors are often insufficient for complete treatment. Consequently, there is a growing demand for therapies with novel mechanisms of action. PharmAbcine plans to continue its research with the goal of initiating a Phase 2 trial after confirming the safety and efficacy of the 4mg multiple-dose cohort. The Company expects PMC-403 to play a pivotal role in the global market for AMD treatments. Beyond ophthalmology, PMC-403 is being explored in therapeutic areas, including vascular-related rare diseases, Acute Respiratory Distress Syndrome, Inflammatory Bowel Disease, Duchenne Muscular Dystrophy, Traumatic Spinal Cord Injury, oncology and kidney diseases. The Company has collaborated with Dr. Kirk Druey, former Chief of the NIH's Lung and Vascular Inflammation Section, to explore PMC-403's efficacy in animal models for Systemic Capillary Leak Syndrome (SCLS, also known as Clarkson disease). In a recent interview, Dr. Druey expressed excitement about PMC-403's potential in treating SCLS patients. While there is currently no approved treatment for SCLS, PMC-403 received Orphan Drug Designation (ODD) from the U.S. FDA for the treatment of SCLS on February 21, 2023.
