Palsonify’s Global Expansion: A New Era for Acromegaly Treatment
Crinetics Pharmaceuticals is rapidly expanding the reach of Palsonify (paltusotine), the first and only once-daily oral treatment for acromegaly in adults who haven’t responded adequately to surgery or aren’t candidates for it. A recent Marketing Authorization Application (MAA) submission in Brazil signals the company’s commitment to making this innovative therapy available worldwide. This follows FDA approval in the United States and a positive opinion from the European Committee for Medicinal Products for Human Use (CHMP).
The Unmet Need in Acromegaly Management
Acromegaly, a rare hormonal disorder caused by the pituitary gland producing too much growth hormone, traditionally requires monthly injections of somatostatin receptor ligands (SRLs). These injections can cause injection site reactions in up to 77% of patients, and symptoms can worsen before the next dose. Palsonify offers a significant improvement in convenience and symptom control, addressing a substantial unmet need in the acromegaly market.
How Palsonify Works: Targeting SST2 Receptors
Paltusotine is a selectively-targeted somatostatin receptor type 2 (SST2) nonpeptide agonist. It’s designed for oral administration and boasts over 4,000-fold selectivity for SST2 compared to other SST receptor subtypes, potentially minimizing off-target effects. Clinical trials, including PATHFNDR-1 and PATHFNDR-2, have demonstrated Palsonify’s ability to maintain IGF-1 levels and symptom control in patients switching from injections, and rapidly decrease IGF-1 levels in previously untreated patients. IGF-1 is a key biomarker used by endocrinologists to monitor acromegaly.
Beyond Acromegaly: Expanding Applications for Paltusotine
Crinetics isn’t limiting paltusotine’s potential to acromegaly. The drug is as well in Phase 3 clinical development for carcinoid syndrome associated with neuroendocrine tumors (NETs). Early results from a Phase 2 study show promising reductions in flushing episodes and bowel movement frequency – common and debilitating symptoms of carcinoid syndrome.
Crinetics’ Broader Pipeline: A Focus on Endocrine Disorders
Palsonify is just one component of Crinetics’ extensive pipeline. The company is also developing atumelnant for congenital adrenal hyperplasia and ACTH-dependent Cushing’s syndrome, and CRN09682, a drug conjugate for SST2-expressing neuroendocrine tumors. Further research programs target conditions like Graves’ disease, polycystic kidney disease, hyperparathyroidism, diabetes, obesity, and GPCR-targeted oncology.
Future Trends in Acromegaly and NET Treatment
The approval and global rollout of Palsonify represent a shift towards more patient-centric treatments for acromegaly and related endocrine disorders. We can anticipate several key trends:
- Oral Therapies Becoming the Standard: The convenience of oral medications is a major driver of patient adherence and quality of life. Expect to see continued development of oral therapies for conditions traditionally managed with injections.
- Targeted Therapies with Reduced Side Effects: Paltusotine’s high selectivity for SST2 exemplifies the trend towards therapies designed to minimize off-target effects and improve the safety profile.
- Personalized Medicine Approaches: As our understanding of the genetic and molecular basis of these diseases grows, we may see more personalized treatment strategies tailored to individual patient characteristics.
- Expansion of NET Treatments: The promising results of paltusotine in carcinoid syndrome suggest a growing focus on developing effective therapies for these challenging tumors.

Acromegaly can cause a variety of physical changes, including enlarged hands and feet, a coarsening of facial features, and excessive sweating. Early diagnosis and treatment are crucial to prevent long-term complications.
Frequently Asked Questions (FAQ)
Q: What is acromegaly?
A: Acromegaly is a hormonal disorder that develops when the pituitary gland produces too much growth hormone.

A: Palsonify is the first and only once-daily oral treatment for acromegaly, offering a more convenient alternative to monthly injections.
Q: Is Palsonify available worldwide?
A: Palsonify is currently approved in the United States and under review in Europe and Brazil.
Q: What other conditions is paltusotine being investigated for?
A: Paltusotine is also in Phase 3 clinical development for carcinoid syndrome associated with neuroendocrine tumors.
Pro Tip: If you or someone you know is experiencing symptoms of acromegaly, consult with an endocrinologist for diagnosis and treatment options.
