PNA Highlights March 2023

PNA Spotlight: Dr. Yuval Eisenberg

This month the PNA Spotlight shines on Dr. Yuval Eisenberg. Dr. Eisenberg graduated from the Rush Medical College of Rush University Medical Center in 2009. He works in Chicago, IL and 2 other locations and specializes in Endocrinology, Diabetes & Metabolism and Internal Medicine. Dr. Eisenberg is affiliated with University Of Illinois Hospital Health & Science Center. He was kind enough to answer some of our questions:

PNA Medical Corner: The Size of Pituitary Microadenomas .

This month the PNA Medical Corner showcases a study co-authored by Drs. Edward Laws and Ursula Kaiser, both longtime members of the PNA. The study looks at the size of microadenomas over time. It concludes that two-thirds of microadenomas studied either stayed the same or shrank over time, and therefore that “less frequent pituitary MRI surveillance for patients with incidental pituitary microadenomas may be safe.”

New acromegaly drug on the horizon

A new drug for treatment and long-term maintenance therapy for acromegaly is now on the horizon. Crinetics Pharmaceuticals recently submitted its first new drug application (NDA) to the U.S. Food and Drug Administration for paltusotine, which is a once-daily oral selectively-targeted somatostatin receptor type 2 nonpeptide agonist.

Crinetics says researchers used data from from 18 clinical trials in the application, including two Phase 3 trials that evaluated paltusotine for acromegaly in medically untreated and treated patients. Patients tolerated the treatment well, the medication achieved biochemical control by maintaining IGF-1 levels and improved patients’ symptoms compared to placebo. The company says it expects to hear back from the FDA by December.

Paltusotine, is the first drug of its type to complete Phase 3 clinical development for acromegaly and is now in Phase 2 clinical development for carcinoid syndrome associated with neuroendocrine tumors. Read the company’s press release here.
