Plain English
This study evaluated the combination of two drugs, vorinostat (VOR) and hydroxychloroquine (HCQ), in patients with advanced colorectal cancer that hasn't responded to other treatments. In a group of 20 patients, the average time without cancer progression was about 2.8 months, and the average overall survival time was 6.7 months. The treatment showed signs of enhancing the immune response to tumors while also inhibiting a cell process called autophagy, which might contribute to cancer growth. Who this helps: This benefits patients with advanced colorectal cancer who have not responded to existing therapies.

Tan AR, Sarantopoulos J, Lee L, Reyderman L, He Y +2 more

Plain English
This study looked at how well the cancer drug eribulin mesylate is processed in the bodies of patients with different levels of kidney function. It found that patients with moderate renal impairment needed lower doses (1.1 mg/m²) to have similar drug exposure as those with normal kidney function who received the standard dose of 1.4 mg/m². This matters because it helps ensure that patients with kidney issues can still receive effective treatment without experiencing unnecessary side effects. Who this helps: Patients with moderate to severe kidney impairment undergoing cancer treatment.

Journal of gastrointestinal oncology

Patel SR, Karnad AB, Ketchum NS, Pollock BH, Sarantopoulos J +2 more

Plain English
This study looked at how effective treatments that inhibit VEGF (a protein that helps tumors grow) are for patients with metastatic colorectal cancer (mCRC). Researchers found that while VEGF inhibitors like bevacizumab can delay the progression of the disease (with improvements seen in 3-4 months of progression-free survival), they do not significantly extend overall survival compared to other types of treatments. This is important because it raises questions about whether these treatments should still be used in later stages of cancer when better options may exist. Who this helps: This information is useful for doctors treating patients with metastatic colorectal cancer.

Phase II study evaluating the efficacy, safety, and pharmacodynamic correlative study of dual antiangiogenic inhibition using bevacizumab in combination with sorafenib in patients with advanced malignant melanoma.

2014

Cancer chemotherapy and pharmacology

Mahalingam D, Malik L, Beeram M, Rodon J, Sankhala K +7 more

Plain English
This study looked at a treatment for advanced melanoma using two drugs: sorafenib and bevacizumab, which aim to block tumor growth by stopping blood vessel formation. Out of 14 patients treated, none showed tumor reduction, but 57% had stable disease for at least 16 weeks, with three patients maintaining stability for over a year, and the average time before their condition worsened was 32 weeks. Some patients experienced side effects, like high blood pressure and fatigue, but those with lower levels of a protein related to blood vessel growth had better outcomes, staying stable for about 50 weeks compared to only 15 weeks in those with higher levels. Who this helps: This research benefits patients with advanced melanoma by potentially guiding future treatment options based on their VEGF levels.

Malik L, Mejia A, Parsons H, Ehler B, Mahalingam D +3 more

Plain English
This study looked at early-stage clinical trials (Phase I) of cancer drugs to see which factors might predict if a drug would eventually gain approval from the FDA. The researchers analyzed data from 88 cancer drugs tested between 2000 and 2013, finding that drugs showing a better response rate — with 423 people having complete responses and 342 showing partial responses — were more likely to be approved. The findings suggest that how well a drug performs in these early trials can indicate its chances of later approval, which is important because it could help streamline the drug development process. Who this helps: This benefits patients and doctors by potentially speeding up access to effective cancer treatments.

Phase I study of cabazitaxel plus cisplatin in patients with advanced solid tumors: study to evaluate the impact of cytochrome P450 3A inhibitors (aprepitant, ketoconazole) or inducers (rifampin) on the pharmacokinetics of cabazitaxel.

2014

Cancer chemotherapy and pharmacology

Sarantopoulos J, Mita AC, Wade JL, Morris JC, Rixe O +5 more

Plain English
This study looked at how different medications affect the levels of cabazitaxel, a cancer treatment drug, in patients with advanced solid tumors. Researchers found that taking the drug ketoconazole decreased cabazitaxel clearance by 20%, while rifampin increased it by 21%. This matters because using drugs that strongly influence how cabazitaxel is processed in the body can alter its effectiveness and safety, so these combinations should be avoided. Who this helps: This benefits cancer patients who may be prescribed cabazitaxel as part of their treatment.
