Phenomix Sciences Revolutionizes Obesity Treatment with Precision Medicine Approach

5 months ago3 min read

Key Insights

  • Phenomix Sciences has developed MyPhenome™, a saliva-based genetic test that identifies specific obesity phenotypes, enabling personalized treatment approaches for better patient outcomes.

  • Research reveals three major obesity subtypes - Hungry Gut, Hungry Brain, and Emotional Hunger - each requiring different therapeutic interventions, with GLP-1 medications showing varying effectiveness across subtypes.

  • The company is partnering with pharmaceutical companies to enhance drug development and clinical trials, potentially revolutionizing obesity treatment through targeted therapies similar to oncology's precision medicine model.

Building on over a decade of Mayo Clinic research, Phenomix Sciences is transforming obesity treatment by introducing a precision medicine approach that challenges traditional one-size-fits-all methods. The company's groundbreaking work reveals that obesity is not a singular condition but rather comprises multiple distinct subtypes, each requiring tailored therapeutic interventions.

Pioneering Personalized Obesity Care

At the heart of this innovation is the MyPhenome™ test, a saliva-based genetic assessment that identifies a patient's specific obesity phenotype. This diagnostic tool provides crucial insights into treatment responsiveness, helping clinicians select the most effective interventions, whether they be medications, surgical procedures, or lifestyle modifications.
"The research demonstrated that obesity is not one disease, but many; each of which should be treated with different interventions," explains Mark Bagnall, CEO of Phenomix Sciences. The test has already gained significant adoption among obesity specialists, particularly in Chicago and Florida.

Understanding Obesity Subtypes

Phenomix's research has identified three primary obesity phenotypes:
  • Hungry Gut: Characterized by rapid stomach emptying, these patients show four times better response to GLP-1 medications
  • Hungry Brain: Patients with brain-driven hunger signals who typically respond better to alternatives like Qsymia or bariatric surgery
  • Emotional Hunger: Individuals struggling with cravings and emotional eating patterns, who may benefit more from treatments like Contrave or behavioral interventions

GLP-1 Medications and the Rule of Thirds

The effectiveness of popular GLP-1 receptor agonists like Ozempic and Wegovy varies significantly among patients. "Obesity specialists will tell you that their experience with GLP-1 medications follows the rule of 'one-thirds': one third of the patients will do really well, one third will experience good but not spectacular weight loss and one third will not benefit at all," Bagnall notes.

Advancing Drug Development Through Precision Medicine

Phenomix's approach extends beyond individual patient care to reshape pharmaceutical research and development. The company is collaborating with multiple pharmaceutical companies to enhance clinical trial design and outcomes. This partnership aims to:
  • Improve drug efficacy through targeted patient population selection
  • Reduce trial failures by identifying likely responders
  • Optimize dosing strategies for maximum effectiveness
  • Minimize side effects through personalized approaches

Future Implications and Expansion

The company's vision extends beyond current applications. "Phenotyping is still in its early stages, and we believe hundreds of additional obesity subtypes are yet to be identified," says Bagnall. The platform shows promise for predicting obesity-related conditions such as diabetes, heart disease, and certain cancers.
Phenomix is actively working with insurance providers to integrate obesity phenotyping into coverage policies, ensuring cost-effective prescription of expensive medications like GLP-1s to patients most likely to benefit.
As the field of obesity medicine evolves, Phenomix's precision medicine approach represents a significant step toward more effective, personalized treatment strategies. The company's work suggests that, like oncology, the future of obesity care lies in targeted therapies based on individual patient characteristics.
