Combination of Optune® with Temozolomide Demonstrates Unprecedented Five-Year Survival for Newly Diagnosed Glioblastoma Patients

Excerpt:

“Novocure (NVCR) announced today results from its phase 3 pivotal EF-14 trial adding Optune to temozolomide for the treatment of newly diagnosed glioblastoma (GBM), including results from health-related quality of life analyses, were presented at the American Society for Radiation Oncology’s (ASTRO) 2017 Annual Meeting in San Diego. This marks the first presentation of EF-14 five-year survival and quality of life data at a radiation oncology conference.

“A late-breaking oral presentation focused on Novocure’s EF-14 phase 3 pivotal trial, which demonstrated unprecedented five-year survival results in newly diagnosed GBM. Patients treated with Optune in combination with temozolomide experienced a significant extension of overall survival without added toxicity compared to patients treated with temozolomide alone. The data also showed that Optune-treated patients were able to maintain quality of life for longer compared to patients treated with temozolomide alone.”

In Breast Cancer, a Victory for Common Sense

Excerpt:

“New 10-year results from a major clinical trial in breast cancer confirm that it does not compromise overall survival to leave behind minimal amounts of cancer that have spread to the underarm lymph nodes in certain patients, according to the investigators.

“The long-term data are from the American College of Surgeons Oncology Group Z0011 trial and were published online September 12 in JAMA.

“The study participants were women with clinical T1 or T2 invasive breast cancer, no palpable axillary nodes, and 1 or 2 sentinel lymph nodes containing metastases. In addition to lymph node management, all patients were treated with lumpectomy, tangential whole-breast irradiation, and adjuvant systemic therapy.”

Three-Drug Regimen Active in BRAF-Mutant Melanoma

Excerpt:

“Triplet therapy for advanced, BRAF V600-mutant melanoma led to objective responses in 73% of a small group of patients enrolled in a phase I trial, according to updated results reported at the 2017 ESMO Annual Congress in Madrid.

“Ongoing follow-up in the trial showed that 11 of 15 patients responded to the combination of pembrolizumab (Keytruda), dabrafenib (Tafinlar), and trametinib (Mekinist). Seven of the 11 responding patients had not progressed after a median follow-up of 20 months. ‘Updated results of the phase I portion of the KEYNOTE-022 trial confirmed previously reported efficacy of this triplet combination,’ said Antoni Ribas, MD, PhD, a professor of medicine, surgery, and molecular and medical pharmacology at the University of California at Los Angeles. ‘The results demonstrated durability of responses. No late or unexpected toxicities occurred with longer follow-up. The randomized phase II portion of KEYNOTE-022 is ongoing.’ ”

Radiation-Immunotherapy Combination Can Slow Tumor Growth for Some Patients With Metastatic Late-Stage Cancer

Excerpt:

“A new study involving patients with stage IV cancer finds that treatment with radiation therapy and immunotherapy can halt the growth of tumors by stimulating the body’s immune system to attack the cancer. In the phase II trial, patients with end-stage cancer that had spread to the lungs or liver demonstrated a favorable response to the combined treatment. Between 30 and 60 percent of the patients, depending on the treatment arm, found that their cancer stopped spreading. Findings will be presented today at the 59th Annual Meeting of the American Society for Radiation Oncology (ASTRO).”

Long-Term Survival Rates More Than Double Previous Estimates for Locally Advanced Lung Cancer

Excerpt:

“Long-term results of a phase III clinical trial indicate that survival rates for patients receiving chemoradiation for unresectable, locally advanced non-small cell lung cancer (NSCLC) may be more than twice as high as previous estimates. At five years following treatment with a standard dose of 60 Gray (Gy) radiation delivered in 30 fractions, the overall survival rate was 32 percent, setting a new benchmark of survival for patients with inoperable stage III NSCLC. The trial, RTOG 0617, also confirms that a standard dose of radiation therapy is preferable to a higher dose and that cetuximab offers no additional survival benefit for these patients. Findings will be presented today at the 59th Annual Meeting of the American Society for Radiation Oncology (ASTRO) in San Diego.”

Ipilimumab Shows Promise in Mutated NSCLC, but Toxicities May Limit Use

Excerpt:

“The addition of ipilimumab to targeted therapy for the treatment of EGFR- and ALK-mutated non-small cell lung cancer demonstrated improved survival despite dose-dependent toxicities, according to results from a phase 1b trial presented at the International Association for the Study of Lung Cancer Multidisciplinary Symposium in Thoracic Oncology.

“Ipilimumab (Yervoy, Bristol-Myers Squibb), a CTLA-4 inhibitor, has demonstrated long-term responses in patients with melanoma; however, the drug is associated with a high rate of grade 3 and grade 4 immune-related adverse events.”

Pivotal Role Remains With Bone-Targeting Agents in mCRPC

Excerpt:

“Prostate cancer researchers are continuing to explore strategies to optimally integrate bone-targeted agents into patient care.

“For example, an ongoing trial is assessing the combination of a radiopharmaceutical, radium-223 dichloride (Xofigo), with an androgen receptor-directed therapy, either abiraterone acetate (Zytiga) or enzalutamide (Xtandi). The open-label, phase IIa study is accruing patients with metastatic castration-resistant prostate cancer (mCRPC). The primary endpoint of the trial, which hopes to enroll 68 patients, is patient bone scan response rate (NCT02034552).”

New Trends in Pre-Surgery Treatments for Breast Cancer


Non-metastatic breast cancers are most often treated with surgery, but if the tumors are fairly large, or involve nearby lymph nodes, neoadjuvant (pre-operative) treatments with chemotherapy (NAC) are done first. NAC often reduces the tumor size and kills cancer cells in lymph nodes, if present, prior to surgery, improving the outcome. The best possible result of neoadjuvant treatment is pCR (pathologic compete response), when the tumor is no longer visible in imaging studies. Here, I review the new directions in which neoadjuvant treatments are evolving.

Today, treatments for metastatic breast cancers are tailored for specific subtypes. Starting with the introduction of the drug trastuzumab (Herceptin) for HER2-positive cancers, new, more specific treatment options were eventually developed and approved for other types as well. Estrogen deprivation endocrine therapies, lately prescribed in combination with CDK4/6 inhibitors, are used in estrogen receptor (ER)-positive cancers. Triple negative cancers (TNBC) are still treated mostly with chemotherapy, but immune checkpoint drugs and PARP inhibitors are explored in clinical trials, with some successes reported.

However, neoadjuvant treatments (except for HER2+ cancers) remain largely limited to chemotherapy regimens. This is starting to change now, with new approaches tailored to the cancer type being investigated in clinical trials.

In this regard, it is important to mention the I-SPY2 trial, NCT01042379, which started in 2010 and is for women with stage II-III breast cancer. It offers about a dozen drugs that are chosen based on particular features of the newly diagnosed cancers. This trial has a unique design and has produced some important results. Additional treatments and trials for various types of breast cancer are discussed below. Continue reading…


Neoadjuvant Dabrafenib/Trametinib Leads to High pCR Rates in Bulky Resectable Melanoma, But Recurrences Are Common

Excerpt:

“Phase II results demonstrated that nearly half of patients with resectable stage IIIB/C BRAF V600-mutant melanoma achieved pathologic complete response (pCR) with neoadjuvant combination therapy consisting of dabrafenib (Tafinlar) and trametinib (Mekinist). Additionally, no patients experienced disease progression during the neoadjuvant treatment, said Alexander M. Menzies, MD, who presented the data at the 2017 ESMO Congress in Madrid.

” ‘Nearly 50% of our patients had a complete eradication of their melanoma at the time of surgery. Fifty percent had some remaining melanoma in the surgical specimen, but every patient had some degree of tumor shrinkage on therapy,’ said Menzies, a medical oncologist and senior research fellow at Melanoma Institute Australia in Sydney, Australia. ‘These are patients who otherwise would just have surgery and then have observation. And, these are patients who are at very high risk, probably the highest risk of recurrence without further therapy.’ ”
