Adding Paraplatin to Alimta Increases Survival in Lung Cancer Study

Results from a phase III clinical trial suggest that adding carboplatin (Paraplatin) to pemetrexed (Alimta) can improve outcomes in non-small cell lung cancer (NSCLC). Over 200 patients with advanced NSCLC received first-line treatment with Alimta either by itself or in combination with Paraplatin. The combination of the two chemotherapy agents extended the time before the cancer started growing again, and prolonged survival compared to Alimta alone. However, the combination treatment group had a higher incidence of serious side effects and four treatment-associated deaths.


Comparison of Combination Chemotherapy Regimens Shows No Significant Differences

Both pemetrexed (Alimta) plus carboplatin (Paraplatin) and Paraplatin plus paclitaxel (Taxol/Abraxane) plus bevacizumab (Avastin) are effective chemotherapy regimens against non-small cell lung cancer (NSCLC). However, until recently, the safety and efficacy of the two regimens had not been directly compared. To evaluate whether one regimen was superior, a phase III clinical trial determined how long patients with advanced non-squamous NSCLC remained free of either cancer progression or severe toxic side effects when treated with either of the two regimens. While patients receiving the Alimta plus Paraplatin regimen tended to have slightly longer relapse- and toxicity-free periods than those given Paraplatin plus Taxol/Abraxane plus Avastin, the difference was not very pronounced and could have happened by chance. The two regimens also did not differ regarding overall time until cancer progression, response rate and overall survival time.


Oncolytics Cancer Drug Meets Mid-Stage Trial Goal, Shares Rise

“Oncolytics Biotech Inc said preliminary data from a mid-stage trial showed that its cancer drug, Reolysin, met the main goal of reducing the size of tumors in patients with metastatic melanoma, a type of skin cancer.”


Randomized Phase II Study of Ixabepilone or Paclitaxel Plus Carboplatin in Patients With Non–Small-Cell Lung Cancer Prospectively Stratified by Beta-3 Tubulin Status

This randomized phase II study evaluated ixabepilone-based chemotherapy in stage IIIb/IV NSCLC, compared with paclitaxel-based chemotherapy. Tumor specimens were prospectively evaluated for beta-3 tubulin (β3T) expression.

There was no predictive value of β3T in differentiating clinical activity of ixabepilone– or paclitaxel-containing regimens. β3T expression seems to be a negative prognostic factor, but not a predictive factor, in advanced NSCLC treated with either ixabepilone or paclitaxel platinum-based doublets.


New Clinical Trial of Drug OGX-427 Aims to Help Patients Ineligible for Targeted Therapies

OncoGenex Pharmaceuticals announced that it will begin the Spruce clinical trial, a phase II study investigating the use of their cancer drug OGX-427 in non-small cell lung cancer (NSCLC). Patients with advanced non-squamous NSCLC will receive first-line treatment with chemotherapy using carboplatin (Paraplatin) and pemetrexed (Alimta), either with or without the addition of OGX-427. OGX-427 inhibits a protein called Hsp27, which is elevated in many cancers. The study investigators suggest that OGX-427 may be especially helpful for patients whose cancers lack certain mutations that would make them eligible for currently available targeted therapies.


Oncolytics lung cancer drug effective in mid-stage trial, shares up

Oncolytics Biotech Inc said its experimental lung cancer drug was found to be more effective in a mid-stage trial study, sending its shares up more than 10 percent.”


The addition of amifostine to carboplatin and paclitaxel based chemoradiation in locally advanced non-small cell lung cancer

We report the long-term results of RTOG 9801, a randomized trial investigating the ability of amifostine, a radioprotector, to reduce chemoradiation-induced esophagitis.

The chemoradiation regimen of carboplatin and paclitaxel produced long-term results in the multi-institutional setting comparable to other regimens. Amifostine did not appear to compromise survival. As done in RTOG 9801, more consistent reporting of long term toxicity is needed for comparison of different chemoradiation regimens.


Alimta-Paraplatin Combination Appears to Be Effective Treatment for Elderly Lung Cancer Patients

Most elderly patients with advanced non-small cell lung cancer (NSCLC) do not receive chemotherapy and no age-specific guidelines for choosing chemotherapy agents exist. A phase II clinical trial investigated treatment with pemetrexed (Alimta) and carboplatin (Paraplatin) for elderly (age 70+ years) patients with advanced NSCLC and little functional impairment. The combination treatment was as effective in these patients as it had been in younger populations in previous studies and it was more effective than either pemetrexed or carboplatin alone. While some patients experienced serious side effects, especially blood-related complications, overall toxicity was acceptable, suggesting that combined Alimta and Paraplatin may be a viable treatment option for similar patients.


Pemetrexed and carboplatin, an active option in first-line treatment of elderly patients with advanced non-small cell lung cancer (NSCLC): A phase II trial

The combination pemetrexedcarboplatin could be a valuable treatment option in elderly patients, as indicated by this phase II trial. Neutropenia was the most common toxicity. The objective tumor response rate is within the range of data reported for pemetrexedcarboplatin in the general NSCLC population.
