Breaking Barriers in Cancer Care: Oral Medication Shows Promise for Chemotherapy Side Effects
For patients battling gastrointestinal cancers, the journey through chemotherapy is often interrupted by a common but debilitating obstacle: chemotherapy-induced thrombocytopenia (CIT). This condition, characterized by low blood platelet counts, often forces clinicians to delay or reduce life-saving treatment doses, which can negatively impact overall patient outcomes.
However, recent results from a phase 2 clinical trial offer a glimpse of a more seamless future for cancer treatment. Researchers at the Sylvester Comprehensive Cancer Center, part of the University of Miami Miller School of Medicine, and Mass General Hospital have identified that an oral medication, avatrombopag, may provide a significant breakthrough for those struggling to maintain the platelet counts necessary to stay on schedule with their chemotherapy.
Platelets are vital blood cells that help the body form clots. When counts drop too low due to chemotherapy, patients face a heightened risk of life-threatening bleeding even from minor injuries.
The Power of Oral Treatment Options
Avatrombopag is a thrombopoietin receptor agonist already approved for use in patients with liver disease. In the recent clinical trial, the drug demonstrated remarkable efficacy in helping patients with gastrointestinal cancers recover their platelet levels. Among the trial participants, 65% of those receiving avatrombopag met key treatment goals, compared to just 17% of those in the placebo group.
Gerald A. Soff, M.D., chief of classical hematology at Sylvester, who led the trial, emphasized the importance of these findings. “These are the patients, based on our experience, who have the greatest need and will benefit the most from use of a thrombopoietin receptor agonist,” Soff noted.
One of the most significant advantages of this medication is its oral administration. Currently, many treatments for CIT require frequent trips to an infusion center for injections. For patients already dealing with the physical and emotional burden of metastatic cancer, eliminating the need for weekly travel can significantly improve their quality of life.
“You can imagine if someone is dealing with metastatic cancer and they’re not feeling great, and they’re trying to maintain a life, having to go in every single week for a shot is not ideal,” Soff said. “If there’s a good oral option, that would be very appealing for many people.”
Why Consistency in Chemotherapy Matters
The primary goal of this therapy is to avoid compromising cancer treatment. When platelet counts remain high, patients can receive their chemotherapy as originally scheduled. According to Soff, there is clear evidence that dose reductions or delays can impact cancer outcomes. By stabilizing platelet counts, clinicians hope to keep patients on their intended treatment trajectory without interruption.

If you or a loved one are experiencing treatment delays due to low blood counts, discuss the latest clinical trial developments with your oncologist. Asking about emerging oral options can be a proactive way to manage your care plan.
Looking Ahead: The Future of CIT Management
While the initial study focused on patients with gastrointestinal cancers to ensure consistent data, researchers believe the benefits could extend to many other tumor types. The trial was so effective that researchers were able to complete their analysis at 23 patients, rather than the original goal of 40. Moving forward, the team is continuing to monitor these patients to understand the long-term benefits of the medication.
As the medical community continues to explore thrombopoietin receptor agonists, the shift toward convenient, patient-friendly oral treatments represents a major step forward in supportive oncology care.
Frequently Asked Questions
What is chemotherapy-induced thrombocytopenia (CIT)?
CIT is a common side effect of chemotherapy where the body’s blood platelet count drops, making it challenging for the blood to clot properly and often requiring a delay in cancer treatment.

Why is an oral medication preferred over injections?
Oral medications allow patients to manage their condition at home, reducing the need for frequent, often difficult travel to clinics or infusion centers for injections.
Is avatrombopag currently approved for CIT?
While avatrombopag is FDA-approved for thrombocytopenia in patients with liver disease, it is not yet approved for CIT. However, recent clinical trials have shown significant promise for this use.
