PEN-866 is a Small Molecule owned by Tarveda Therapeutics, and is involved in 1 clinical trial, which is ongoing.

PEN-866 works by delivering SN-38 to tumor cells. SN-38 is an active metabolite of irinotecan which acts by blocking an enzyme, called topoisomerase I. Blocking of this enzymes leads to DNA tang which prevent cells from dividing. Hsp90 is up-regulated in a variety of tumor cells, plays a key role in the conformational maturation, stability and function of client proteins within the cell, many of which are involved in signal transduction, cell cycle regulation and apoptosis, including kinases, transcription factors and hormone receptors. By delivery of the cytotoxic payload to the cancer cells, it causes regressions of tumors.

The revenue for PEN-866 is expected to reach a total of $134m through 2038. This change impacts the valuation of this asset and is an important factor to understand the current value of the drug in a clinical process. View the complete picture with the PEN-866 NPV Report.

PEN-866 was originated by Synta Pharmaceuticals and is currently owned by Tarveda Therapeutics. SciClone Pharmaceuticals Holdings is the other company associated in development or marketing of PEN-866.

PEN-866 Overview

PEN-866 is under development for the treatment of small cell lung cancer, rhabdomyosarcoma, triple negative breast cancer, colorectal cancer, Ewing sarcoma, gastric adenocarcinoma, ovarian cancer and pancreatic adenocarcinoma and liposarcoma. The drug candidate is a Hsp90 inhibitor linked to SN-38 via a cleavable chemical linker. SN-38 acts by targeting topoisomerase I. The drug candidate is developed based on Hsp90-inhibitor drug conjugates (HDCs) platform technology. It is administered through intravenous route. It was also under development for the treatment of non-small cell lung cancer, bladder cancer and melanoma.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.

To create this model, GlobalData takes into account factors including patent law, known and projected regulatory approval processes, cash flows, potential applicable patients, drug margins, company expenses, and pricing estimates. Combining these data points with GlobalData’s world class analysis creates high value models that companies can use to help in evaluation processes for each drug or company.

The rNPV method integrates the probability of a drug reaching a clinical stage into the cash flow at that time, which provides a more accurate rNPV, as it considers the probability that the drug never makes it through the clinical pathway to commercialization. GlobalData’s rNPV model uses proprietary likelihood of approval (LoA)and phase transition success rate(PTSR) data for the indication in the highest development stage, which can be found on GlobalData’s Pharmaceutical Intelligence Center.
