FDA Approves Tepylute (thiotepa) Ready-to-Dilute Injectable Formulation to Treat Breast Cancer and Ovarian Cancer

Shorla Oncology (‘Shorla’), a U.S.-Ireland specialty pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has approved the company’s New Drug Application (NDA) for Tepylute, a ready-to-dilute formulation to treat breast and ovarian cancer in an easier to prepare, injectable product that enables dosing accuracy.

Shorla Oncology (‘Shorla’), a U.S.-Ireland specialty pharmaceutical company, announced today that the U.S. Food and Drug Administration (FDA) has approved the company’s New Drug Application (NDA) for Tepylute, a ready-to-dilute formulation to treat breast and ovarian cancer in an easier to prepare, injectable product that enables dosing accuracy.1

‘’This approval fulfills an unmet need by addressing the shortcomings and handling complexities of the current lyophilized powder formulation,” said Sharon Cunningham, Chief Executive Officer and Co-Founder of Shorla Oncology. “We have taken a vital oncology drug and made it easier for oncology clinics and hospitals to use, while also reducing medical personnel exposure to a hazardous drug.”

Tepylute, formerly SH-105, is the third FDA-approved drug for Shorla, and a significant milestone for the company as it seeks approval for several cancer-fighting drugs for the U.S. market.

“The approval of Tepylute represents an important milestone for Shorla as our first in-house developed NDA,” said Orlaith Ryan, Chief Technical Officer and Co-Founder of Shorla Oncology.

Tepylute is a liquid form of a well-established, standard of care oncology drug, thiotepa. The new formulation eliminates the need for complex and time-consuming reconstitution. It provides consistent dosing accuracy and allows for “just in time” preparation.2

“Among Tepylute’s many benefits, it removes the necessity to reconstitute which can introduce additional risks of drug preparation errors,” emphasized Rayna Herman, Chief Commercial Officer. “We look forward to providing an update on our launch plans for Tepylute in the near future.”

The American Cancer Society estimates that more than 300,000 women will be diagnosed with breast cancer in the U.S in 2024.3 About 19,680 women will be diagnosed with ovarian cancer in the United States.4

Shorla Oncology is currently marketing two products with a robust pipeline including SH-201, the first palatable oral liquid treatment for certain forms of leukemia and other cancers. In April, the company announced the FDA had accepted SH-201 for an NDA review with an expected action date of November 30, 2024.

Combination of heat, doxorubicin drug and nanotech system may improve ovarian cancer treatment

The combination of heat, chemotherapeutic drugs and an innovative delivery system based on nanotechnology may significantly improve the treatment of ovarian cancerwhile reducing side effects from toxic drugs, researchers at Oregon State University report in a new study.

The findings, so far done only in a laboratory setting, show that this one-two punch of mild hyperthermia and chemotherapy can kill 95 percent of ovarian cancer cells, and scientists say they expect to improve on those results in continued research.

The work is important, they say, because ovarian cancer - one of the leading causes of cancer-related deaths in women - often develops resistance to chemotherapeutic drugs if it returns after an initial remission. It kills more than 150,000 women around the world every year.

"Ovarian cancer is rarely detected early, and because of that chemotherapy is often needed in addition to surgery," said Oleh Taratula, an assistant professor in the OSU College of Pharmacy. "It's essential for the chemotherapy to be as effective as possible the first time it's used, and we believe this new approach should help with that."

It's known that elevated temperatures can help kill cancer cells, but heating just thecancer cells is problematic. The new system incorporates the use of iron oxidenanoparticles that can be coated with a cancer-killing drug and then heated once they are imbedded in the cancer cell.

Other features have also been developed to optimize the new system, in an unusual collaboration between engineers, material science experts and pharmaceutical researchers.

A peptide is used that helps guide the nanoparticle specifically to cancer cells, and the nanoparticle is just the right size - neither too big nor too small - so the immune system will not reject it. A special polyethylene glycol coating further adds to the "stealth" effect of the nanoparticles and keeps them from clumping up. And the interaction between the cancer drug and a polymer on the nanoparticles gets weaker in the acidic environment of cancer cells, aiding release of the drug at the right place.

"The hyperthermia, or heating of cells, is done by subjecting the magnetic nanoparticles to an oscillating, or alternating magnetic field," said Pallavi Dhagat, an associate professor in the OSU School of Electrical Engineering and Computer Science, and co-author on the study. "The nanoparticles absorb energy from the oscillating field and heat up."

The result, in laboratory tests with ovarian cancer cells, was that a modest dose of the chemotherapeutic drug, combined with heating the cells to about 104 degrees, killed almost all the cells and was far more effective than either the drug or heat treatment would have been by itself.

Doxorubicin (see structure), the cancer drug, by itself at the level used in these experiments would leave about 70 percent of the cancer cells alive. With the new approach, only 5 percent were still viable.

The work was published in the International Journal of Pharmaceutics, as a collaboration of researchers in the OSU College of Pharmacy, College of Engineering, and Ocean NanoTech of Springdale, Ark. It was supported by the Medical Research Foundation of Oregon, the PhRMA Foundation and the OSU College of Pharmacy.

Drug Duo of Ixabepilone and sunitinib Kills Chemotherapy-resistant Ovarian Cancer Cells......

In continuation of Sunitinib...

The use of two drugs never tried in combination before in ovarian cancer resulted in a 70 percent destruction of cancer cells already resistant to commonly used chemotherapy agents, say researchers at Mayo Clinic in Florida. Research  suggests that this combination (ixabepilone and sunitinib), might offer a much needed treatment option for women with advanced ovarian cancer. When caught at late stages, ovarian cancer is often fatal because it progressively stops responding to the chemotherapy drugs used to treat it. The finding also highlights the importance of the role of a molecule, RhoB, that the researchers say is activated by the drug duo. Neither drug is approved for use in ovarian cancer. Ixabepilone is a chemotherapy drug that, like other taxane drugs, targets the microtubules and stops dividing cells from forming a spindle. It has been approved for use in metastatic breast cancer. Sunitinib, approved for use in kidney cancer, belongs to a class of tyrosine kinase inhibitors that stops growth signals from reaching inside cancer cells.
