Botensilimab

HealthScout AI summary: Adults with metastatic, microsatellite-stable pancreatic ductal adenocarcinoma that has progressed on at least one prior systemic therapy receive SBRT to selected lesion(s) followed by dual checkpoint blockade with botensilimab (Fc‑enhanced anti–CTLA‑4) plus balstilimab (anti–PD‑1). Eligible patients require ECOG 0–1, measurable disease, adequate organ function, ≤25% liver tumor burden, and no active CNS metastases or significant autoimmune/immunosuppression.

ClinicalTrials.gov ID: NCT06843551

HealthScout AI summary: This trial enrolls adults with microsatellite stable, KRAS-mutant metastatic colorectal cancer who have progressed on or are intolerant of standard chemotherapy, and excludes those with diabetes or prior anti-PD1/CTLA-4 therapy. Patients receive combination therapy with botensilimab (Fc-engineered anti-CTLA-4 antibody), balstilimab (anti-PD-1 antibody), a fasting-mimicking diet, and high-dose intravenous vitamin C.

ClinicalTrials.gov ID: NCT06336902

HealthScout AI summary: Previously untreated, metastatic pancreatic ductal adenocarcinoma (ECOG 0–1) receiving triplet chemotherapy (nab-paclitaxel/gemcitabine/cisplatin) plus chloroquine and celecoxib, combined with dual checkpoint blockade: botensilimab (Fc‑engineered anti–CTLA‑4 designed to enhance T-cell priming/Treg depletion) and balstilimab (anti–PD‑1). Key exclusions include prior metastatic therapy, CNS mets, active autoimmune disease or prior checkpoint inhibitors, significant CV/GI disease, uncontrolled infections, retinal disease/G6PD deficiency, and warfarin/digoxin use.

ClinicalTrials.gov ID: NCT06076837

HealthScout AI summary: This trial enrolls adults with newly diagnosed, metastatic or unresectable, microsatellite stable colorectal cancer (no liver, bone, or brain metastases, ECOG 0-1, and no prior systemic therapy for metastatic disease), testing combination immunotherapy with botensilimab (Fc-enhanced anti-CTLA-4) and balstilimab (PD-1 inhibitor), with mFOLFOX6 plus bevacizumab or panitumumab added if disease progresses.

ClinicalTrials.gov ID: NCT06268015

HealthScout AI summary: This trial enrolls adults with unresectable or metastatic, mismatch repair-proficient colorectal cancer or pancreatic ductal adenocarcinoma harboring vaccine-covered KRAS mutations who have progressed after first-line chemotherapy, and treats them with a mutant KRAS-targeted peptide vaccine plus balstilimab (anti-PD-1) and botensilimab (Fc-enhanced anti-CTLA-4). Immunotherapy-naive patients with measurable disease and good performance status are eligible.

ClinicalTrials.gov ID: NCT06411691

HealthScout AI summary: Adults with unresectable/metastatic esophageal, gastric, or GEJ adenocarcinoma after one prior line (or relapse ≤6 months after perioperative therapy), ECOG 0–1, receive ramucirumab plus paclitaxel combined with investigational immunotherapies: agenT‑797 (allogeneic invariant NKT cell therapy targeting CD1d-presented glycolipids), botensilimab (Fc‑enhanced CTLA‑4 inhibitor), and balstilimab (PD‑1 inhibitor). Excludes prior ramucirumab, recent taxane, severe prior irAEs from PD‑(L)1/CTLA‑4, active CNS mets, significant neuropathy, or active viral infections.

ClinicalTrials.gov ID: NCT06251973

HealthScout AI summary: Adults with newly diagnosed, IDH-wild type, MGMT-unmethylated GBM post-radiotherapy (ECOG 0–2) receive Sonocloud-9–mediated blood–brain barrier opening every 3 weeks synchronized with liposomal doxorubicin plus balstilimab (anti–PD-1) and botensilimab (Fc‑enhanced anti–CTLA‑4). Excludes prior immunotherapy, multifocal/not-coverable or posterior fossa disease, active autoimmune disease, and other major comorbidities.

ClinicalTrials.gov ID: NCT05864534

HealthScout AI summary: Previously untreated adults with unresectable/metastatic clear cell RCC (all IMDC risk groups; ECOG 0–2; treated/stable brain mets allowed) are randomized to botensilimab (Fc‑enhanced anti‑CTLA‑4) plus balstilimab (anti‑PD‑1) versus standard ipilimumab/nivolumab. The trial compares objective response and durability/safety, with early efficacy focus on intermediate/poor risk disease.

ClinicalTrials.gov ID: NCT05928806

HealthScout AI summary: Adults with advanced or metastatic soft tissue sarcoma (multiple histologies; ECOG 0–1) eligible for doxorubicin and without prior anthracycline or checkpoint inhibitor receive doxorubicin plus dual checkpoint blockade. Part 1 uses balstilimab (anti–PD‑1) with zalifrelimab (anti–CTLA‑4); Part 2 explores botensilimab (Fc‑enhanced anti–CTLA‑4) ± balstilimab with doxorubicin.
