Summary

This trial is testing a new drug called OBI-999 on its own. It focuses on patients with advanced solid tumors who need new treatment options. The goal is to find out the highest safe dose and see if the drug helps in treating the tumors.

Who is the study for?
This trial is for adults with advanced solid tumors, specifically pancreatic, esophageal, gastric, or colorectal cancer. Participants must have tried standard treatments without success or declined them and have a good performance status (able to carry out daily activities). They need functioning major organs and agree to use contraception. Those with HIV or hepatitis are eligible under certain conditions.
What is being tested?
The study tests OBI-999 as a solo treatment to find the highest dose patients can tolerate without severe side effects (MTD) and the recommended dose for future Phase 2 trials (RP2D). It also aims to understand how safe OBI-999 is and its preliminary effectiveness in shrinking or controlling tumor growth.
What are the potential side effects?
Specific side effects of OBI-999 aren't listed but typically include reactions related to the immune system's response, potential organ inflammation due to drug toxicity, general discomforts like fatigue or nausea, and possibly changes in blood counts leading to increased infection risk.

Trial Design

2Treatment groups
Experimental Treatment
Group I: OBI-999 Expansion PhaseExperimental Treatment1 Intervention
Part B: Five cohorts of patients at RP2D of OBI-999 liquid form, as determined from Part A, via IV infusion.
Group II: OBI-999 Escalation phaseExperimental Treatment1 Intervention
Part A: Five cohorts at escalating dose levels 0.4, 0.8, 1.2, 1.6 and 2.0 mg/kg (capping calculations at a maximum at 100 kg) of OBI-999 liquid form via IV infusion to establish maximum tolerated dose (MTD) and Recommended phase 2 dose (RP2D).

Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
Common treatments for solid tumors include chemotherapy, targeted therapy, and immunotherapy. Chemotherapy works by killing rapidly dividing cells, which includes cancer cells, but also affects healthy cells, leading to side effects. Targeted therapies, such as tyrosine kinase inhibitors, specifically target molecular abnormalities in cancer cells, minimizing damage to normal cells. Immunotherapy, including checkpoint inhibitors, enhances the body's immune response against cancer cells. Understanding these mechanisms is crucial for patients as it helps in selecting the most appropriate treatment, managing side effects, and improving overall outcomes. New treatments like OBI-999, though not specified, likely aim to exploit specific vulnerabilities in cancer cells, offering hope for more effective and personalized cancer care.
