TTP607 in Refractory Solid Malignancies

The goal of this clinical research study is to find the highest tolerable dose of TTP607 that can be given to patients with a solid tumor or lymphoma. The safety of TTP607 will also be studied.

Researchers will also do pharmacokinetic (PK) testing of TTP607. PK testing measures the amount of a drug in the body at different time points.

The Study Drug:

TTP607 is designed to work by blocking the action of certain enzymes (proteins) in the blood that are responsible for abnormal growth of cancer cells. This may cause the cancer cells to eventually die.

Dose Level Assignment:

If you are found to be eligible to take part in this study, you will be enrolled in a group of 3-6 participants. The dose you receive will be based on when you join this study (on how many participants have been enrolled before you, and on the safety data that is available at that time). The first group of participants will receive the lowest dose of TTP607. Each new group of participants will receive the next highest dose of the study drug, as long as no intolerable side effects occur. This process will continue until the highest tolerable dose of TTP607 is reached. Once the highest tolerable dose is found, 12 additional participants will be enrolled and treated at that dose, so that researchers can learn more about the effects of the study drug on the tumor. Both you and your study doctor will know what dose of the study drug you are receiving.

Study Drug Administration:

Starting on Day 1 of Cycle 1, you will receive TTP607 by central venous catheter (CVC or central venous line). There are several types of central venous catheters. Each type of catheter is a flexible, long, thin tube that is inserted through a vein, under a local anesthetic, through a small cut in your chest (near your heart). Some chemotherapy drugs are not suitable to be given into the veins in your hand or arm, so these drugs must be given into a larger vein. The CVC may also be used for drawing blood samples that are needed regularly. Using the CVC for these blood draws will lower the need for repeated blood draws from your arm. TTP607 will be given over 1-4 hours depending on the dose you receive, each day for 5 days in a row, followed by a 10-day "rest period" (no study drug). This 15 days is considered 1 cycle.

Study Visits:
