Trastuzumab imbotolimod [Phase 2 (discontinued)]
Identified from the Human Clinical Data
| Experiment 1 Reporting the Activity Date of This ADC | [1] | ||||
| Efficacy Data | Partial Response (PR) |
27%
|
|||
| Patients Enrolled |
Eligible patients must have HER2-positive advanced solid tumors with exhausted treatment options, measurable disease (RECIST 1.1), ECOG 0-1, and available tumor tissue. Exclusions include hypersensitivity to study drugs, prior TLR7/8 agonist treatment, cardiac dysfunction, active infections (HIV, HBV, HCV, SARS-CoV-2), and untreated CNS metastases. Other protocol-specific criteria may apply.

| Administration Dosage |
Pts with HER2+ (protein or gene) or HER2-low solid tumors progressing after standard therapies (Txs) were enrolled. BDC-1001 was given IV q3w, q2w, or q1w as monotherapy (mono; n=94) and q2w or q1w with nivolumab 240mg q2w (combo; n=37).

| NCT Number | NCT04278144 | Clinical Status | PHASE1|||PHASE2 | ||
| Clinical Description |
Phase 1/2 Study of BDC-1001 As a Single Agent and in Combination with Nivolumab in Patients with Advanced HER2-Expressing Solid Tumors
|
||||
| Primary Endpoint |
The study evaluates safety (AEs, SAEs, DLTs, and immune-related toxicities) and determines the maximum tolerated dose (MTD) during the escalation phase, alongside assessing ORR of complete/partial responses (CR/PR) in the expansion phase over a 2-year timeframe.
|
||||
| Other Endpoint |
Pharmacokinetic parameters (Cmax, Cmin, AUC, CL, Vz, t1/2) of BDC-1001 are measured during both escalation and expansion periods, alongside efficacy outcomes (ORR, DOR, DCR, PFS per RECIST 1.1) and immunogenicity (anti-BDC-1001 antibodies) over 2 years.
|
||||
| Experiment 2 Reporting the Activity Date of This ADC | [2] | ||||
| Patients Enrolled |
Eligible participants must have confirmed HER2+ breast adenocarcinoma (IHC 3+/ISH+/NGS+) with ≥2 prior anti-HER2 therapies (including trastuzumab deruxtecan), measurable disease, ECOG 0-1, and biopsy/archival tissue. Key exclusions cover hypersensitivity to BDC-1001/pertuzumab, prior TLR7/8 agonist treatment, significant cardiac disease, active viral infections, and unstable CNS metastases.

| Related Clinical Trial | |||||
| NCT Number | NCT05954143 | Clinical Status | PHASE2 | ||
| Clinical Description |
Phase 2, Multi-Center, Randomized, Open-Label Trial of BDC-1001 As a Single Agent and in Combination with Pertuzumab in Subjects with HER2-Positive Metastatic Breast Cancer Previously Treated with Trastuzumab Deruxtecan
|
||||
| Primary Endpoint |
The efficacy of BDC-1001 alone and combined with pertuzumab is evaluated through Objective Response Rate (ORR) per RECIST v1.1 at 12 weeks.
|
||||
| Other Endpoint |
Additional endpoints include long-term efficacy (DOR, DCR, PFS, OS up to 24 months), safety (TEAEs/TESAEs), pharmacokinetics (Cmin, Cmax), and immunogenicity (anti-BDC-1001 ADAs) during the 24-month period for both single-agent and combination therapy.
|
||||
| Experiment 3 Reporting the Activity Date of This ADC | [3] | ||||
| Patients Enrolled |
Patients with advanced metastatic HER2-expressing (IHC2/3+) or amplified solid tumors. Patients had received a median of 4 prior therapies.
|
||||
| Administration Dosage |
4 dose levels (0.15-5.00 mg/kg) every 3 weeks.
