Breakthrough Clinical Results
Bolt Biotherapeutics announced an update on its Phase 1 dose escalation study of BDC-4182, an ISAC targeting claudin 18.2 for cancer treatment. Initial clinical data is expected in Q3 2026. The company is modifying the trial protocol to allow for step-up dosing, based on preclinical data. To conserve capital, Bolt is implementing a 50% workforce reduction, extending its cash runway into 2027. The company is focusing on the clinical advancement of BDC-4812 and supporting ISAC collaborations to increase shareholder value.

Emerging Mechanism of Action
Emerging Mechanisms of Action for Cancer Treatment
Recent publications highlight several key mechanisms of action emerging in cancer treatment:
Immune System Interactions
- Chronic infections by pathogenic microorganisms play a significant role in cancer development by disrupting the immune system and microenvironment
- Understanding the immune microenvironment offers potential for new immunotherapy targets
- Tilsotolimod, a novel investigational toll-like receptor 9 agonist, demonstrates extensive tumor microenvironment immunomodulation
- Immune checkpoint inhibitors represent a significant advancement but can cause neuro-ophthalmic adverse events
Cellular Mechanisms
- Cancer stem cells (CSCs) represent a critical mechanism in cancer biology, escaping traditional anti-oncogenic treatments and triggering metastases and relapses
- Polyploid giant cancer cells (PGCCs) are critical for tumor survival, resistance, and immortalization
- Metabolic heterogeneity in cancer cells shows some primarily depend on glycolysis, while others favor mitochondrial oxidative phosphorylation (OXPHOS)
- Multimodal cell death pathways including apoptosis, autophagy, pyroptosis and ferroptosis show unique advantages in inhibiting colorectal cancer
Signaling Pathways
- The AMPK/PGC-1α signaling pathway plays a crucial role in cancer cell metabolism via targeting energy homeostasis and mitochondria biogenesis
- Natural products target the MAPK-signaling pathway in cancer therapy
- Wnt signaling pathway aberration has been linked with various cancers, with approximately 30 phytochemicals identified to modulate this pathway
- Targeting the PI3K-Akt-mTOR pathway and enhancer of zester homolog 2 (EZH2) shows promise for treatment
- The adenosine pathway regulates inflammation, apoptosis, metastasis, and cell proliferation in breast cancer cells
Novel Therapeutic Approaches
- Photodynamic therapy (PDT) generates predominantly singlet oxygen or reactive oxygen radicals leading to cellular apoptosis and necrosis
- Poly(ADP-ribose) polymerase inhibitors (PARPi) have gained FDA approval for patients with homologous recombination repair gene mutations
- Radioligand therapy (RLT) with Lu-PSMA-617 shows promise
- Tyrosine kinase inhibitors (TKIs) target oncogenic kinases associated with advanced radioactive iodine refractory thyroid cancer
- Melatonin (MLT) has shown specific effects in reducing stomatitis rate and easing depression in cancer patients
Precision Medicine Advances
- Precision oncology is tailored to facilitate cancer diagnosis, prevention, and treatment based on patients' genetic profiles
- Advancements in "Omics" techniques and next-generation sequencing support personalized approaches
- Artificial intelligence applications enhance diagnostic and treatment capabilities
- Personalized therapeutics including immunotherapy and cancer vaccines represent the future of treatment
Emerging End Points
Key Endpoints Emerging for Cancer Treatment in Recent Research
Survival and Response Endpoints
- Overall survival has become a key endpoint in cancer treatment, particularly with immune checkpoint modulation which produces durable responses and overall survival benefits with less toxicity
- Progression-free survival is increasingly important, as demonstrated with pembrolizumab in first-line treatment of Stage IV NSCLC with 50% PD-L1 expression
- Disease-free survival is commonly used alongside OS and PFS in recent cancer research
- Response to neoadjuvant chemotherapy (NAC) is emerging as a valuable endpoint, with Ki-67 being particularly useful in predicting this response
Toxicity and Side Effect Management
- Reduced toxicity is emerging as a critical endpoint, with studies showing immune checkpoint modulation produces benefits with less toxicity compared to conventional chemotherapy
- Treatment-related adverse events are increasingly reported alongside efficacy endpoints
- Multi-component herbal products have shown effectiveness in ameliorating chemotherapy-induced neurotoxicity, gastrointestinal toxicity, hematological toxicity, cardiotoxicity, hepatotoxicity and nephrotoxicity
- Cutaneous squamous cell carcinoma (cuSCC) is being monitored as an adverse event in targeted therapies
Biomarkers and Personalized Treatment
- Proliferative markers such as Ki-67, mini chromosome maintenance (MCM) proteins, and proliferating cell nuclear antigen (PCNA) offer valuable insights into tumor growth and treatment response
- Post-chemotherapy changes in Ki-67 levels are linked to survival outcomes
- PD-L1 expression levels (particularly ≥50%) are used to determine which patients will benefit from immunotherapy treatments
Standardized Clinical Trial Endpoints
-
Primary clinical trial endpoints now commonly include:
-
Progression-free survival (PFS)
-
Overall survival (OS)
-
Duration of response (DOR)
-
Overall response rate (ORR)
-
Clinical benefit rate (CBR)
Emerging Treatment Approaches
- Photodynamic therapy (PDT) is showing potential as a therapeutic platform for head, neck, and brain diseases
- Combination therapy approaches are being investigated, including combinations of chemotherapy with cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) inhibitors
- Integration of biomarkers with digital pathology and AI-driven tools may enhance diagnostic accuracy and personalized treatment strategies
Risk Assessment and Management
- Cancer recurrence risk is being evaluated for patients with history of cancer who need treatment for inflammatory conditions
- Contralateral cervical lymph node metastasis rates are being used to determine whether patients with contralateral cN0 oropharyngeal squamous cell carcinoma need contralateral cervical lymph node dissection
- Locoregional recurrence reduction is being measured in treatments like postoperative radiotherapy (PORT) for esophageal squamous cell carcinoma
