What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests a new drug, AVB-S6-500, combined with existing cancer treatment in patients with ovarian cancer that hasn't improved with other treatments. The goal is to see if this new combination works better than the existing treatments alone.

Will I have to stop taking my current medications?

The trial protocol does not specify if you need to stop taking your current medications, but you must wait at least 28 days after your last anti-cancer or hormonal therapy before starting the study drug.

Is the treatment generally safe for humans?

The treatment, which includes pegylated liposomal doxorubicin (PLD) and paclitaxel, has been studied in patients with breast cancer and is generally considered safe with manageable side effects. Common side effects include hand-foot syndrome (skin reaction on palms and soles), mouth sores, and low white blood cell counts, but no serious heart-related issues were observed. ^{1 2 3 4 5}

What makes the drug AVB-S6-500 combined with Paclitaxel and Pegylated liposomal doxorubicin unique?

This drug combination is unique because it uses pegylated liposomal doxorubicin, which delivers the active ingredient directly to the tumor, reducing side effects compared to traditional doxorubicin. Additionally, the combination with paclitaxel has shown effectiveness in treating metastatic breast cancer with manageable side effects, especially in patients at high risk of heart-related issues. ^{1 3 6 7 8}

What data supports the effectiveness of the drug AVB-S6-500, Paclitaxel, Taxol, Onxol, Abraxane, Paclitaxel, Pegylated liposomal doxorubicin (PLD), Placebo, Control, Dummy Treatment?

Research shows that Abraxane, a form of paclitaxel, is effective in treating metastatic breast cancer with less toxicity compared to traditional paclitaxel. Additionally, combining pegylated liposomal doxorubicin (PLD) with paclitaxel has shown a high response rate and manageable side effects in patients with metastatic breast cancer. ^{1 8 9 10 11}

Published Research Related to This Trial

Nab-paclitaxel (Abraxane(®)) has been approved by the FDA for treating breast cancer after chemotherapy failure, showing superior efficacy compared to traditional paclitaxel (Taxol(®)).

This new formulation not only demonstrates better effectiveness but also has less toxicity, which enhances its safety profile and therapeutic index, making it a promising option for combination therapies.

Nab-paclitaxel in the treatment of metastatic breast cancer: a comprehensive review. Montero, AJ., Adams, B., Diaz-Montero, CM., et al.[2021]

In a pilot study involving 17 patients with advanced hepatocellular carcinoma, pegylated liposomal doxorubicin (PLD) demonstrated a clinical benefit response in 50% of participants, including a 7% rate of complete remission.

The treatment was associated with moderate toxicities, suggesting it is relatively safe, and the positive results indicate that further research on PLD for this condition is justified.

Pilot study with pegylated liposomal doxorubicin for advanced or unresectable hepatocellular carcinoma. Schmidinger, M., Wenzel, C., Locker, GJ., et al.[2018]

The maximum tolerated doses (MTD) for pegylated liposomal doxorubicin (PLD) and paclitaxel (PTX) in patients with metastatic breast cancer were determined to be 35 mg/m2 and 160 mg/m2, respectively, indicating a safe dosing strategy for further studies.

In this phase-I study involving 23 patients, the combination of PLD and PTX showed promising efficacy, with 52.6% of evaluable patients achieving an objective response, suggesting that this regimen is active and has manageable toxicity.

A phase-I study evaluating the combination of pegylated liposomal doxorubicin and paclitaxel as salvage chemotherapy in metastatic breast cancer previously treated with anthracycline. Hong, RL., Lin, CH., Chao, TY., et al.[2018]

In a study of 42 patients receiving cumulative doses of pegylated liposomal doxorubicin (doxil) exceeding 500 mg/m2, none developed clinical congestive heart failure, indicating a favorable safety profile for higher doses compared to traditional doxorubicin.

While five patients experienced a drop in left ventricular ejection fraction (LVEF), the overall risk of cardiomyopathy appears significantly lower with doxil, even in patients previously treated with doxorubicin, suggesting that doxil may be a safer option for patients with solid tumors.
