This article explores the multifaceted world of health, examining a novel ovarian cancer treatment, weight loss drugs, and holistic lifestyle approaches to healthy aging. It delves into the specifics of the experimental drug Trebananib (TRINOVA 1, 2, 3) for ovarian cancer, explores the science behind GLP-1 medications like Semaglutide and Tirzepatide for weight loss, and highlights the importance of chronic care management and proactive lifestyle choices for maintaining overall well-being.
Trebananib: A Novel Approach to Ovarian Cancer Treatment
Trebananib represents a new class of anti-angiogenic agents in ovarian cancer treatment, targeting the angiopoietin 1/2 pathway instead of the more commonly targeted VEGF pathway.
Angiogenesis and its role
Angiogenesis, the formation of new blood vessels, plays a crucial role in cancer development and progression. Tumors require a blood supply to grow and spread. VEGF (Vascular Endothelial Growth Factor) has been a primary target in anti-angiogenic therapies for ovarian cancer. However, this approach is associated with side effects such as hypertension, bowel perforation, bleeding, thrombosis, wound healing problems, proteinuria, and CNS disturbances.
Trebananib mechanism
Trebananib, on the other hand, inhibits angiogenesis by targeting angiopoietin 1/2, offering a different approach to disrupting tumor blood supply. It also inhibits lymph angiogenesis. Clinical trials, including TRINOVA 1, TRINOVA 2, and TRINOVA 3, have investigated its efficacy and safety. TRINOVA 1 combined trebananib with weekly paclitaxel, while TRINOVA 2 is combining it with pegylated liposomal doxorubicin. TRINOVA 3 is adding it to frontline and combining it with anti-VEGF, especially since it works after anti-VEGF therapy failure. The patients in these trials had up to three prior lines of therapy with a platinum-free interval of less than twelve months.
Efficacy and side effects
While trebananib does not exhibit the classic VEGF-associated toxicities, it is associated with edema (generalized, localized, and pleural effusion) and weight gain, occurring at two to three times the rate seen in the placebo arm. Grade 3 or worse edema was observed in only 2-4% of patients, suggesting it is generally not a serious side effect.

The Future of Trebananib
Researchers are optimistic about trebananib's potential, especially in combination with other cytotoxics and anti-VEGF therapies, offering a new treatment option for patients who have failed prior anti-VEGF treatment.
GLP-1 Medications: A Revolution in Weight Management
GLP-1 (glucagon-like peptide-1) receptor agonists have emerged as a significant tool in managing blood sugar and weight. Drugs like Semaglutide (Ozempic, Wegovy) and Tirzepatide (Mounjaro, Zepbound) have gained popularity for their effectiveness.
How GLP-1 Medications Work
GLP-1 is a naturally occurring hormone in the gut that regulates blood sugar by stimulating insulin release after meals and slowing digestion. GLP-1 medications mimic this hormone, leading to:
- Improved Blood Sugar Control: GLP-1s stimulate the pancreas to produce more insulin when blood sugar levels rise.
- Weight Management: They influence areas of the brain that control appetite, promoting feelings of fullness and reducing calorie intake.
Tirzepatide is unique because it mimics two gut hormones: GLP-1 and GIP (gastric inhibitory polypeptide). While traditionally administered via injection, compounded Tirzepatide is available through some pharmacies.
Retatrutide: The Next Generation?
Retatrutide, an experimental drug from Eli Lilly, has shown even greater weight loss potential in clinical trials. It mimics GLP-1, GIP, and glucagon, a hormone that may reduce appetite and improve metabolism. In a mid-stage trial, participants lost an average of 24% of their body weight (approximately 58 pounds).

Comparing Weight Loss Drugs
Clinical trials have shown the following average weight loss results:
- Semaglutide: Around 15% (34 pounds) after 68 weeks.
- Tirzepatide: Around 22.5% (52 pounds) after 72 weeks.
- Retatrutide: 24.2% (57.8 pounds) after 48 weeks (and weight loss was still increasing).
It's important to note that these results are from separate trials and not direct comparisons.
Potential Side Effects
Common side effects of GLP-1 medications include nausea, vomiting, diarrhea, and constipation. Rapid weight loss, as seen with retatrutide, can increase the risk of gallstones. It is also important to monitor lean body mass, as losing too much can slow down metabolism.
Considerations for Use
Doctors emphasize that obesity is a chronic condition requiring long-term management. While GLP-1 medications can be highly effective, they are not a "quick fix." Some patients may seek to discontinue use due to side effects or having reached their weight goals. However, discontinuing the medication can lead to a return of weight and obesity symptoms, as the drugs suppress the body's natural signals related to energy processing and storage.
GLP-1 Rapid Dissolve Tablets
Trinova Health offers compounded Semaglutide in rapid dissolve tablets (RDTs) as a needle-free alternative to injections. The tablets dissolve under the tongue, allowing the medication to be absorbed directly into the bloodstream, bypassing the stomach.

The Future of GLP-1s
Ongoing research and development promise a range of options for managing weight and related health conditions. As Dr. Skovronsky notes, different medicines will be needed for different patients, and retatrutide could be a valuable option for those who don't respond well to other weight loss medications or need to lose a substantial amount of weight.
Chronic Care Management: A Proactive Approach to Health
Chronic Care Management (CCM) is a comprehensive approach to healthcare for individuals managing two or more chronic conditions, such as diabetes, high blood pressure, heart disease, or arthritis.
What is CCM?
CCM involves ongoing support from a care team between regular office visits, including:
- Medication review and interaction checks
- Prescription refills
- Follow-up on lab results
- Care plan updates
- Communication with specialists
- Post-hospital visit check-ins
Benefits of CCM
CCM provides a healthcare safety net, ensuring that health needs are addressed even when patients are at home. It enables early detection of potential problems and facilitates effective coordination among healthcare providers.
Medicare Coverage
Medicare Part B covers CCM services at 100% for participating practices like Trinova Medical, with no copayment or out-of-pocket costs for patients.
Holistic Health: Lifestyle Choices for Healthy Aging
Healthy aging involves making informed choices to preserve strength, sharpen the mind, and nurture vital connections. Research consistently points to four key pillars:
Pillar 1: Stay Physically Strong
Regular movement reduces the risk of heart disease, diabetes, and certain cancers, while also lowering overall mortality. Strength and balance training are crucial for reducing fall risk and maintaining bone density. The CDC recommends 150 minutes of moderate activity per week.
Pillar 2: Prioritize Preventive Care
Regular screenings for blood pressure, cholesterol, diabetes, certain cancers, and mental health conditions are essential. Medicare covers an annual wellness visit and vaccinations for flu, shingles, pneumonia, and COVID-19.
Pillar 3: Protect Cognitive Sharpness
Regular aerobic activity, blood pressure management, cognitive stimulation, and social engagement can slow cognitive decline. Medicare's annual wellness visit includes an optional cognitive assessment.
Pillar 4: Stay Socially Connected
Social connection is a critical medical risk factor, with loneliness and isolation linked to increased risk of heart disease, stroke, and premature death. Community programs, volunteer groups, exercise classes, and digital tools can help build meaningful connections.
Medication Management: Supporting Independence and Safety
Medication management becomes increasingly complex as people age, due to physiological changes and the number of medications taken.
Common Challenges
- Decreased kidney and liver function
- Vision impairment
- Changes in sense of time
- Cognitive changes affecting memory and attention
Strategies for Success
- Use weekly pill organizers with clear labels.
- Create a simple medication list with drug names, dosages, and timing.
- Consult with a pharmacist to identify potential drug interactions.
- Improve lighting and organization in medication storage areas.
When to Seek Professional Help
Seek immediate medical attention for sudden confusion, dizziness, or falls related to medication errors. Consult a healthcare provider for ongoing concerns about medication management or if the individual feels overwhelmed by their routine.
