“AbbVie (ABBV) announced the initiation of a global Phase III clinical trial evaluating the safety and efficacy of its investigational compound, veliparib (ABT-888), in patients with previously untreated locally advanced or metastatic squamous non-small cell lung cancer (NSCLC). The trial will compare patients randomized to receive either the standard chemotherapies of carboplatin and paclitaxel with the addition of veliparib, versus patients receiving carboplatin and paclitaxel with the addition of placebo.”
Editor’s note: Clinical trials are used to test new cancer treatments. Enrolling in a clinical trial might give a patient access to a promising treatment he/she would otherwise not be able to receive. Learn more about lung cancer clinical trials here.
Adding the drug Imprime PGG to chemotherapy and antibody therapy may be effective for certain patients with non-small cell lung cancer (NSCLC). Imprime PGG contains a molecule called beta glucan, which can stimulate the body’s immune cells to destroy cancer cells. This process may be especially effective in patients with high levels of immune system proteins that bind to beta glucan, so-called antibeta glucan antibodies. In a recent clinical trial, patients with advanced NSCLC received the antibody drug cetuximab (Erbitux) and the chemotherapy agents carboplatin (Paraplatin) and paclitaxel (Taxol/Abraxane), and some were also given Imprime PGG. While survival across all patients was not affected by Imprime PGG treatment, it was increased in Imprime PGG-treated patients with high levels of antibeta glucan antibodies. Seventeen percent of these patients survived 3 years or more, while none of the other patient groups did.
A combination of the drugs carboplatin (Paraplatin), paclitaxel (Taxol/Abraxane), cetuximab (Erbitux), and bevacizumab (Avastin) has demonstrated effectiveness against non-small cell lung cancer (NSCLC) in a phase II clinical trial. One hundred two patients with advanced non-squamous NSCLC received the four-drug combo as a first-line treatment. Tumors shrank in 56% of patients and stopped growing in an additional 21%. Patients went an average of 7 months without their cancer progressing; the average survival time was 15 months. Four treatment-related deaths occurred, including two due to hemorrhage (heavy bleeding), which can be a rare but serious effect of Avastin treatment. This side effect profile was within the predefined safety margin. A phase III trial further investigating this drug combination for NSCLC is currently enrolling participants.
Combining cetuximab (Erbitux), bevacizumab (Avastin), and traditional chemotherapy in patients with non-small cell lung cancer (NSCLC) appeared to be safe and effective in a phase II clinical trial. Patients with advanced non-squamous NSCLC received Erbitux and Avastin in addition to carboplatin (Paraplatin) and paclitaxel (Taxol/Abraxane) as first-line treatment, followed by maintenance treatment with Erbitux and Avastin. Tumors shrank in 56% of patients and stopped growing in an additional 21%. Serious side effects were relatively rare; the rate was comparable to that of either Erbitux or Avastin alone. Both Erbitux and Avastin have shown efficacy in NSCLC by themselves, but may be more effective when given together. An ongoing phase III clinical trial will further investigate this drug combination.

Cetuximab and bevacizumab have each been demonstrated to prolong survival when added to chemotherapy in patients with advanced non-small-cell lung cancer (NSCLC). However, the potential benefit of combining cetuximab and bevacizumab together with a platinum-based doublet had not been explored. We designed this phase II trial to evaluate the safety, tolerability, and efficacy of the combination of carboplatin, paclitaxel, cetuximab, and bevacizumab in chemotherapy-naive patients with advanced, nonsquamous NSCLC.
This regimen was safe, feasible, and effective as a frontline treatment of advanced NSCLC, providing the basis for the ongoing phase III trial S0819.
The makers of lorvotuzumab mertansine (IMGN901) have halted a clinical trial investigating the use of the drug in extensive-stage small-cell lung cancer (SCLC). An independent monitoring group recommended ending the trial because patients treated with IMGN901 in addition to the chemotherapy agents etoposide (Etopophos) and carboplatin (Paraplatin) fared no better than patients treated with Etopophos and Paraplatin only. Furthermore, the patient group receiving IMGN901 appeared to have higher rates of infections and infection-related deaths, with at least one death potentially related to IMGN901.
The recent PointBreak clinical trial compared two treatment regimens for non-squamous non-small cell lung cancer (NSCLC). Previously untreated patients with advanced non-squamous NSCLC received initial treatment with carboplatin (Paraplatin), bevacizumab (Avastin), and either pemetrexed (Alimta) or paclitaxel (Taxol/Abraxane). The Alimta-treated group was then given maintenance treatment with Alimta and Avastin, while the other patients received Avastin only. Alimta treatment was associated with slightly longer times until the cancer progressed again (average 6.0 months, compared to 5.6 in the Alimta-free regimen). However, overall survival did not differ between the groups. The two regimens differed in what specific side effect were most common, but had similar overall toxicities and were generally tolerable.

PointBreak (A Study of Pemetrexed, Carboplatin and Bevacizumab in Patients With Nonsquamous Non-Small Cell Lung Cancer) compared the efficacy and safety of pemetrexed (Pem) plus carboplatin (C) plus bevacizumab (Bev) followed by pemetrexed plus bevacizumab (PemCBev) with paclitaxel (Pac) plus carboplatin (C) plus bevacizumab (Bev) followed by bevacizumab (PacCBev) in patients with advanced nonsquamous non–small-cell lung cancer (NSCLC).
Overall survival did not improve with the PemCBev regimen compared with the PacCBev regimen, although progression-free survival was significantly improved with PemCBev. Toxicity profiles differed; both regimens demonstrated tolerability.
