Advanced PEComa

About Advanced PEComa

PEComas are a rare subset of soft tissue sarcomas recently recognized as a distinct entity by the World Health Organization in 2002 and are composed of histologically and immunohistochemically distinctive epithelioid cells.

PEComas appear to arise most commonly at visceral (especially gastrointestinal and uterine), retroperitoneal, and abdominopelvic sites.

Most PEComas are benign, but there is a subset of PEComas, i.e., advanced malignant PEComas [1], for which there are currently no approved therapies and for which there are only a few case reports in the literature.

The prognosis for this patient subset is poor, with a median survival estimated to be 12-17 months following diagnosis of advanced disease [2].

Overactivation of the mTOR pathway has been reported in malignant PEComa, and mTOR inhibitors have shown anecdotal efficacy in this indication in case reports or retrospective studies [1].

AADi’s phase 2 registrational trial for ABI-009 in patients with advanced PEComa (Perivascular Epithelioid Cell tumors) will be completed in 2019 followed by the NDA submission (NCT02494570).

ABI-009 has received Orphan Designation for PEComa and Fast Track Designation for advanced (metastatic or locally advanced) malignant PEComa.

AADi is also a recipient of FDA’s Orphan Product Development Grant for this indication.

Advanced PEComa

March, 7 2019, Aadi Bioscience, Inc. (Aadi), For the first time in his life, Shanahan “Shanny” Dameral, 19, has a girlfriend. Soon, he’ll be graduating with a high school diploma and looking for his first job on the Kitsap Peninsula. What seems routine for many is a big deal for Dameral and other children living with treatment-resistant or intractable epilepsy. For reasons largely unknown, seizures in this subset of children persist long past their discovery in early childhood despite being treated with multiple medications and undergoing surgery to remove the affected parts of their brain. Diagnosed with epilepsy at age 5, life for Dameral has always come with seizures attached. When his seizures returned after a second brain surgery shortly after his 16th birthday, his mom Linley Allen, hoped for a medical breakthrough. “We needed to find something else since another surgery was out of the question,” Allen said. “We had heard about a drug being studied for a more severe seizure condition. I kept holding onto hope that it might be expanded to treat Shanny’s type of seizures because it was all we had at the time.”   See all and the original News article here: New Drug Trial Gives Hope for Treatment-Resistant Epilepsy
