What is BOLD-100?
BOLD-100 is an investigational drug being studied for the treatment of advanced solid tumors[1]. Its active ingredient is a chemical compound called sodium trans-[tetrachlorobis(1H-indazole)ruthenate(III) dihydrate. This complex name refers to the drug’s chemical structure, which contains the metal ruthenium along with other elements[1].
BOLD-100 is also known by several other names, including:
- NKP-1339 dihydrate
- KP-1339 dihydrate
- IT-139 dihydrate
These alternative names may be used in scientific literature or discussions about the drug[1].
Medical Conditions Treated
BOLD-100 is being investigated for the treatment of several types of advanced solid tumors, including[1]:
- Colorectal Cancer: Cancer that starts in the colon or rectum
- Advanced Solid Gastrointestinal Tumors: Cancers that affect the digestive system
- Pancreatic Cancer: Cancer that begins in the pancreas
- Cholangiocarcinoma: A type of cancer that forms in the bile ducts
These conditions are all considered advanced solid tumors, meaning they are cancers that form solid masses and have progressed to later stages[1].
How BOLD-100 Works
While the exact mechanism of action is not fully described in the provided information, BOLD-100 is being studied in combination with a standard chemotherapy regimen called FOLFOX[1]. FOLFOX is a combination of drugs commonly used to treat various types of cancer, especially colorectal cancer.
The goal of combining BOLD-100 with FOLFOX is to potentially enhance the effectiveness of treatment for patients with advanced solid tumors[1].
Clinical Trial Information
BOLD-100 is currently being studied in a clinical trial called “A Phase 1b/2a Dose Escalation Study of BOLD-100 in Combination with FOLFOX Chemotherapy in Patients with Advanced Solid Tumours”[1]. This trial has two main parts:
- Part A (Dose Escalation): This part aims to assess the safety, tolerability, and determine the Maximum Tolerated Dose (MTD) of BOLD-100 when combined with FOLFOX chemotherapy[1].
- Part B (Dose Expansion): This part will evaluate how well patients respond to the combination of BOLD-100 and FOLFOX chemotherapy[1].
Eligibility Criteria
To participate in this clinical trial, patients must meet certain criteria. Some key eligibility requirements include[1]:
- Being 18 years or older
- Having a confirmed diagnosis of one of the specified advanced solid tumors
- Having received at least one prior line of chemotherapy (for most cancer types)
- Having measurable disease according to specific criteria (RECIST v1.1)
- Being in relatively good overall health, with an ECOG performance score of 0 or 1
There are also several exclusion criteria, such as certain medical conditions or prior treatments that would prevent a patient from participating in the trial[1].
Potential Side Effects
As BOLD-100 is still being studied, all potential side effects may not be known. The clinical trial is designed to monitor for adverse events (side effects) closely. Some areas being watched include[1]:
- Changes in blood tests (chemistry, hematology, coagulation)
- Changes in heart rhythm (monitored by electrocardiograms)
- Changes in vital signs
- Changes in overall physical condition
The severity of side effects will be graded according to standardized criteria (NCI CTCAE Version 5.0)[1].
Important Considerations
If you’re considering participating in this clinical trial or learning more about BOLD-100, keep in mind:
- BOLD-100 is an investigational drug, meaning it’s not yet approved for general use[1].
- The trial combines BOLD-100 with standard chemotherapy (FOLFOX), so participants will receive both treatments[1].
- Participation in clinical trials is voluntary and requires informed consent[1].
- The trial has specific eligibility criteria, and not all patients with the specified cancers will qualify[1].
Always consult with your healthcare provider to determine if participating in a clinical trial is appropriate for your specific situation.
