The FDA today voted to expand the approved use of rivaroxaban (Xarelto, Janssen Pharmaceuticals) to include the treatment of deep vein thrombosis or pulmonary embolism.<br />
<div class="related-links" id="SeeAlso" jquery17101883288525991917="10" style="display: block;">
The drug also now is approved to reduce the risk of recurrence of those two conditions after initial therapy, according to an FDA press release.</div>
“Xarelto is the first oral anti-clotting drug approved to treat and reduce the recurrence of blood clots since the approval of warfarin nearly 60 years ago,” <strong>Richard Pazdur, MD</strong>, director of the Office of Hematology and Oncology Products in the FDA’s Center for Drug Evaluation and Research, said in the release.<br />
The FDA approved the expanded use under its priority review program, which allows for an expedited 6-month review for drugs that offer major advances in treatment or offer a treatment where none exist.<br />
The approval comes after encouraging results from the three EINSTEIN studies, which involved more than 9,000 patients with thromboembolic events. <br />
In July 2011, the FDA approved rivaroxaban to reduce the risk of DVT and PE after knee or hip replacement surgery. In November 2011, the agency approved the drug to reduce stroke risk individuals with non-valvular atrial fibrillation.<br />

CHICAGO — The anti-psychotic medication olanzapine helps to control breakthrough chemotherapy-induced nausea and vomiting that develops when patients do not respond to conventional prophylactic antiemetic treatments, according to results of a phase 3 trial.</div>
<div class="Bodytext">
Chemotherapy-induced nausea and vomiting (CINV) affects up to 90% of patients who undergo certain types of chemotherapy, according to background information provided by researchers. About one-third of those patients experience breakthrough CINV.</div>
<div class="Bodytext">
Olanzapine (Zyprexa, Eli Lily) has been shown to be safe and effective for the prevention of CINV. Researchers hypothesized that olanzapine also may be an effective rescue medication for patients who receive guideline-directed CINV prophylaxis but still experience nausea and vomiting.</div>
<div class="Bodytext">
<strong>Rudolph M. Navari, MD, PhD</strong>, clinical director of the Harper Cancer Institute at Indiana University School of Medicine-South Bend, and colleagues conducted a double-blind, randomized controlled trial to compare olanzapine to metoclopramide, which often is prescribed as a treatment for breakthrough CINV despite a lack of research proving its efficacy for that purpose.</div>
<div class="Bodytext">
Researchers enrolled 205 patients with a median age of 56 years who received guideline-recommended drugs to prevent CINV prior to undergoing their first round of chemotherapy. Eighty of those patients developed breakthrough CINV. Those patients then were randomly assigned to olanzapine 10 mg orally daily for 3 days (n=42) or metoclopramide 10 mg three times a day (n=28) for 3 days. Researchers followed the patients for 72 hours through phone calls from study nurses, and the patients also were asked to keep diaries of their experiences.</div>
<div class="Bodytext">
Thirty (71%) of the patients assigned to olanzapine experienced no vomiting, compared with 12 (32%) of the patients assigned to metoclopramide, a statistically significant difference. Sixty-seven percent of patients assigned to olanzapine reported experiencing no nausea, compared with 24% of patients assigned to metoclopramide, also a statistically significant difference.</div>
<div class="Bodytext">
Both treatments were well tolerated, researchers said.</div>
<div class="Bodytext">
Olanzapine, an FDA-approved treatment for psychosis, causes a variety of side effects when taken daily for 6 months or longer. However, no patients assigned to short-term treatment in this study reported grade-3/grade-4 toxicities, the researchers said.</div>
<div class="Bodytext">
Because breakthrough CINV typically develops between the second and fourth days after the start of chemotherapy, patients would not have to take olanzapine for longer than 3 days, Navari said in a press release.</div>
<div class="Bodytext">
“This is the first time that breakthrough CINV has been studied in a systematic way,” Navari said. “This study suggests that olanzapine will be very useful in these patients who feel very sick and sometimes come to the clinic, hospital or emergency room.”</div>

S. Food and Drug Administration approved enzalutamide (XTANDI® Capsules, Medivation, Inc. and Astellas Pharma US, Inc.), for the treatment of patients with metastatic castration-resistant prostate cancer who have previously received docetaxel. <br />
The approval was based on a single randomized, placebo-controlled, multicenter trial enrolling 1199 patients with metastatic castration-resistant prostate cancer who had received prior docetaxel. Patients were randomly allocated to receive enzalutamide 160 mg orally once daily (N = 800) or placebo (N = 399). Study treatment continued until disease progression, initiation of new systemic antineoplastic treatment, unacceptable toxicity, or withdrawal. Patients were required to continue androgen deprivation therapy and were allowed, but not required, to continue or initiate glucocorticoids during the study period. Forty-eight percent (48%) of patients on enzalutamide and 46% on placebo received glucocorticoids. <br />
The primary efficacy endpoint was overall survival (OS). At the pre-specified interim analysis after 520 events, a statistically significant improvement in OS [HR 0.63 (95% CI: 0.53, 0.75), p < 0.0001, log rank test] was observed. The median OS was 18.4 and 13.6 months in the enzalutamide and placebo arms, respectively. <br />
The most common (≥5%) grade 1-4 adverse reactions included asthenia or fatigue, back pain, diarrhea, arthralgia, hot flush, peripheral edema, musculoskeletal pain, headache, upper respiratory infection, muscular weakness, dizziness, insomnia, lower respiratory infection, spinal cord compression and cauda equina syndrome, hematuria, paresthesia, anxiety, and hypertension. Grade 3-4 adverse reactions were reported in 47% of patients treated with enzalutamide and in 53% of those on placebo. <br />
Seizures occurred in 0.9% of patients on enzalutamide. No patients on the placebo arm experienced seizures. In the clinical trial, patients experiencing a seizure were permanently discontinued from therapy. All seizures resolved. Patients with a history of seizure, taking medications known to decrease the seizure threshold, or with other risk factors for seizures were excluded from the clinical trial. The safety of enzalutamide in patients with predisposing factors for seizures is unknown. <br />
The recommended dose and schedule for enzalutamide is 160 mg orally once daily.HemOnc101http://www.blogger.com/profile/09438681402596018738noreply@blogger.com1tag:blogger.com,1999:blog-2361217360051123887.post-49321871187999188752012-08-06T23:00:00.001-07:002012-08-06T23:00:55.425-07:00New Treatment for Colon Cancer : ziv-aflibercept<br />
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">On August 3, 2012, the U. S. Food and Drug Administration approved ziv-aflibercept injection (ZALTRAP®, Sanofi U.S., Inc.) for use in combination with 5-fluorouracil, leucovorin, irinotecan (FOLFIRI) for the treatment of patients with metastatic colorectal cancer (mCRC) that is resistant to or has progressed following an oxaliplatin containing regimen. Ziv-aflibercept (previously known as aflibercept) is a recombinant fusion protein consisting of vascular endothelial growth factor (VEGF)-binding portions from the extracellular domains of human VEGF receptors 1 and 2 that are fused to the Fc portion of the human IgG1 immunoglobulin. </span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">This approval is based on the results of a randomized, double-blind, placebo-controlled, global, multicenter trial enrolling patients with mCRC that progressed during or within 6 months of receiving oxaliplatin-based combination chemotherapy, with or without prior bevacizumab.</span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">The Phase 3 trial accrued 1226 patients who were randomly allocated (1:1) to receive FOLFIRI (irinotecan 180 mg/m2 IV infusion over 90 minutes, leucovorin 400 mg/m² IV infusion over 2 hours, followed by 5-FU 400 mg/m² IV bolus, followed by 5-FU 2400 mg/m² continuous IV infusion over 46-hours) with either ziv-aflibercept (N=612) or placebo (N=614). Ziv-aflibercept was administered at a dose of 4 mg/kg IV infusion over 1 hour prior to FOLFIRI. The treatment cycles on both arms were repeated every 2 weeks. Patients were treated until disease progression or unacceptable toxicity. The primary efficacy endpoint was overall survival (OS). Treatment assignment was stratified by the ECOG performance status and prior exposure to bevacizumab.</span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">Median age of randomized patients was 61 years, 59% were men, and 98% had an ECOG performance status of 0 or 1. All patients had received prior oxaliplatin treatment. A statistically significant improvement in OS was observed in patients receiving FOLFIRI plus ziv-aflibercept compared to those receiving FOLFIRI plus placebo [HR 0.82 (95% CI: 0.71, 0.94), p=0.0032, stratified log-rank test]. The median OS was 13.5 and 12.06 months for patients on the ziv-aflibercept and placebo arms, respectively. Median progression-free survival in the ziv-aflibercept arm was 6.9 compared to 4.7 months in the placebo arm [HR 0.76 (95% CI: 0.66, 0.87), p=0.00007]. </span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">The most common adverse reactions, (all grades), occurring in greater than or equal to 20% of patients in the ziv-aflibercept plus FOLFIRI arm (with greater than or equal to 2% difference between arms) were leukopenia, diarrhea, neutropenia, proteinuria, increased AST and ALT, stomatitis, fatigue, thrombocytopenia, hypertension, decreased weight, decreased appetite, epistaxis, abdominal pain, dysphonia, increased serum creatinine, and headache. The most common grade 3-4 adverse reactions (greater than or equal to 5%) reported at a higher incidence in the ziv-aflibercept plus FOLFIRI arm (greater than or equal to 2% difference between arms) were neutropenia, diarrhea, hypertension, leukopenia, stomatitis, fatigue, proteinuria, and asthenia. </span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">Severe and sometimes fatal hemorrhages, including gastrointestinal hemorrhages, have been reported in patients receiving ziv-aflibercept. Grade 3-4 hemorrhagic events occurred in 2.9% of patients receiving FOLFIRI plus ziv-aflibercept compared with 1.7% of those receiving FOLFIRI plus placebo. In addition to hemorrhage, the ziv-aflibercept label contains a Boxed Warning for the serious adverse reactions gastrointestinal perforation and compromised wound healing. </span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">Arterial thromboembolic events were observed in 1.7% and 2.6% of patients in the placebo and ziv-aflibercept containing arms, respectively. Venous thromboembolic events were also observed more frequently with ziv-aflibercept: 9% patients in the ziv-aflibercept-containing arm compared to 7% in the placebo-containing arm. Fistula formation and reversible posterior leukoencephalopathy syndrome have also been reported in patients who received ziv-aflibercept.</span></div>
<div style="color: #222222; font-family: Arial; font-size: 13px;">
<span style="font-family: Verdana; font-size: x-small;">The recommended ziv-aflibercept dose and schedule is 4 mg/kg administered as a 60-minute IV infusion every 2 weeks in combination with the FOLFIRI regimen.</span></div>HemOnc101http://www.blogger.com/profile/09438681402596018738noreply@blogger.com1tag:blogger.com,1999:blog-2361217360051123887.post-57527675317665030522012-04-27T05:59:00.001-07:002012-04-27T05:59:18.630-07:00FDA Approves GSK Cancer Drug Votrient For Soft-Tissue Sarcoma<span class="Apple-style-span" style="font-family: Arial, Helvetica, sans-serif; font-size: 11px; line-height: 10px;"></span><br />
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
WASHINGTON (Dow Jones)--The Food and Drug Administration on Thursday approved GlaxoSmithKline PLC's (GSK, GSK.LN) cancer drug Votrient for use in patients with soft-tissue sarcoma, making it the first new treatment for the rare type of cancer in decades.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
Votrient, a tablet taken orally, is already on the U.S. market to treat advanced kidney cancer. It was approved to treat several subtypes of advanced soft-tissue sarcoma, after prior chemotherapy. The disease starts in muscle or other connective tissues in the body.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
The National Cancer Institute estimates there are about 11,000 cases of soft-tissue sarcomas diagnosed in the U.S. each year.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
Votrient's approval follows the March recommendation of an agency advisory panel, which voted, 11-2, that the drug's benefits outweighed the risks. Clinical data involving 369 patients showed the drug temporarily slowed tumor growth.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
Specifically, the study showed patients being treated with Votrient had a median progression-free survival of 4.6 months compared with 1.6 months on the placebo, or a difference of three months in the time before the cancer starts to worsen.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
The FDA noted that Votrient carries the agency's toughest boxed warning, telling patients and health-care professionals about the potential risk of liver damage, which can be fatal. Patients should be monitored for liver function and treatment should be discontinued if liver function declines, the agency said.</div>
<div style="display: block; font-size: 1.3em; line-height: 1.5em; margin-bottom: 1em; margin-left: 0px; margin-right: 0px; margin-top: 0px; padding-bottom: 0px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">
The most common side effects seen in Votrient-treated patients were fatigue, diarrhea, nausea, weight loss, high blood pressure, decreased appetite, vomiting, tumor and muscle pain, hair color changes, headache, a distorted sense of taste, shortness of breath, and skin discoloration, the FDA said.</div>

<div class="headingAnchor2" id="H4"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h2">Continuum of care concept</span> — With most types of incurable cancer (other than metastatic colorectal cancer), individual chemotherapy drugs or regimens are given continuously until the cancer stops responding to that drug or regimen, and then an entirely new regimen (termed "second-line therapy") may be tried.</span></span></div><span style="font-family: Times, "Times New Roman", serif; font-size: large;">The situation is different with metastatic colorectal cancer because there are many active drugs that can be combined in a number of ways. In addition, treatment-related side effects may be lessened by limiting the number of doses of certain drugs. Thus, instead of giving the first-line regimen until the tumor progresses, treatment is often individualized.</span><br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<ul class="bullet-block"><li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Specific chemotherapy drugs may be given, stopped, and then restarted at a later time, sometimes in combination with other chemotherapy drugs. </span></li>
<li><span style="font-family: Times; font-size: large;"></span></li>
<li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Periods of aggressive chemotherapy may be interspersed with periods of "maintenance" chemotherapy, allowing the patient to have the greatest possible quality of life while minimizing side effects.</span></li>
</ul><span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;">This has been referred to as the "continuum of care" approach to treatment of metastatic colorectal cancer.</span><br />
<br />
<div class="headingAnchor2" id="H5"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h2">Conventional chemotherapy</span> — The conventional chemotherapy drugs used to treat metastatic colorectal cancer include:</span></span></div><span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<ul class="bulletCompact-block"><li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">5-fluorouracil (abbreviated FU), which is usually given into the vein with a second drug called leucovorin, which enhances its activity </span></li>
<li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Orally active FU-like drugs, such as capecitabine (Xeloda®) </span></li>
<li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Oxaliplatin (Eloxatin®), which is given intravenously </span></li>
<li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Irinotecan (Camptosar®), also given intravenously</span></li>
</ul><span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;">These drugs work by interfering with the ability of rapidly growing cells (like cancer cells) to divide or reproduce themselves. Because most of an adult's normal cells are not actively growing, they are less affected by chemotherapy, with the exception of bone marrow (where the blood cells are produced), the hair, and the lining of the gastrointestinal tract. Effects of chemotherapy on these and other normal tissues cause side effects during treatment. </span><br />
<br />
<span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h2">Targeted chemotherapy</span> — Three other drugs that are active against metastatic colorectal cancer work by a different mechanism. These are referred to as "targeted chemotherapy agents" since they are antibodies (a type of protein) that work to inhibit a specific protein that is important for the growth and/or survival of colon cancer cells.</span></span><br />
<br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;">Because targeted chemotherapy does not directly interfere with rapidly dividing cells, they do not have the usual side effects of conventional chemotherapy. However, targeted chemotherapy has other unique side effects, which are described in detail below.</span><br />
<br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;">Currently available targeted chemotherapy includes:</span><br />
<br />
<div class="headingAnchor2" id="H7"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h3"><strong>Bevacizumab (Avastin®)</strong></span> — Bevacizumab binds to a protein called vascular endothelial growth factor (VEGF). VEGF is involved in the development of a blood supply within a growing cancer; this blood supply is essential for the tumor to grow and spread. Bevacizumab enhances the antitumor effect of other chemotherapy drugs. Bevacizumab is not effective when given by itself, but is generally given in combination with other drugs, such as oxaliplatin and irinotecan </span></span></div><div class="headingAnchor2"><br />
</div><div class="headingAnchor2" id="H8"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h3"><strong>Cetuximab (Erbitux®)</strong></span> — Cetuximab targets a different protein, the epidermal growth factor receptor (EGFR), which is found in about 80 percent of colorectal cancers. Erbitux® is effective even if EGFR is not found in an individual tumor.</span></span></div><span style="font-family: Times, "Times New Roman", serif; font-size: large;">Cetuximab does not work for all patients. It depends on whether or not the tumor has a specific abnormality (a mutation in a gene called K-ras).</span><br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<ul class="bullet-block"><li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">If the tumor has a K-ras mutation, cetuximab does not work. </span></li>
<li><span style="font-family: Times, "Times New Roman", serif; font-size: large;">If the tumor does not have a K-ras mutation, cetuximab does work (ie, it is effective).</span></li>
</ul><span style="font-family: Times, "Times New Roman", serif; font-size: large;"></span><br />
<span style="font-family: Times, "Times New Roman", serif; font-size: large;">Unlike bevacizumab, cetuximab is active when given alone or in combination with other drugs, like irinotecan. </span><br />
<br />
<div class="headingAnchor2" id="H9"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h3"><strong>Panitumumab (Vectibix®)</strong></span> — Like cetuximab, panitumumab also targets the EGFR. Like cetuximab, it is effective only for tumors that do not have a specific mutation in the K-ras gene.</span></span></div><div class="headingAnchor2"><br />
</div><div class="headingAnchor2" id="H10"><span style="font-family: Times, "Times New Roman", serif;"><span style="font-size: large;"><span class="h2">Monitoring during treatment</span> — A person's response to chemotherapy is monitored with periodic X-ray studies (such as CT scans) every six to eight weeks during therapy. In addition, blood levels of a tumor marker called carcinoembryonic antigen (CEA) are generally measured every one to three months during therapy. CEA levels are typically high in people with advanced colorectal cancer; persistently rising CEA levels suggest that disease is progressing and a change in therapy is warranted.</span></span></div><div class="headingAnchor2"><br />
</div><span style="font-family: Times, "Times New Roman", serif; font-size: large;">However, a rising CEA alone is not sufficient evidence to prompt a change in treatment. Disease progression should be confirmed with radiographic testing (eg, CT scan) or a biopsy before changing treatment.</span><br />

Max Topp, MD, from the University Hospital of Wuerzburg, Germany, presented the interim results in a poster here at the 16th Congress of the European Hematology Association (EHA).<br />
Blinatumomab appears to represent a new treatment option for patients with treatment-refractory ALL, he noted. "This is the first clinical evidence that this technology might provide the fifth pillar of cancer therapy. We are testing it in the most aggressive B-cell malignancy we know," he told <em>Medscape Medical News</em> in an interview.<br />
<div sizcache="0" sizset="35">The primary end point of the single-group, multicenter, exploratory <a href="http://www.clinicaltrials.gov/ct2/show/NCT01209286?term=blinatumomab&rank=1" target="_blank"><span style="color: #004276;">phase 2 trial</span></a> was the rate of CR or CR+. Secondary end points were toxicity and duration of response.</div>"Based on the results from the first 12 patients, there is reasonable hope that this will change the way we think about this disease," said Dr. Topp.<br />
A previous phase 2 trial with blinatumomab, presented at the 2010 American Society of Hematology annual meeting, reported results from ALL patients who showed minimal residual disease (MRD) or leukemic cells in the bone marrow, despite having received chemotherapy. Results of this previous study showed that 80% (16 of 20) achieved MRD-negativity, all within the first treatment cycle. Disease-free survival was 60% after a follow-up of up to 27.5 months.<br />
<b>Dismal Prognosis for Relapsed/Refractory ALL</b> <br />
Blinatumomab is the first of a new class of agents designed to direct cytotoxic T-cells to CD19-expressing cancer cells. CD19 is a protein expressed on the surface of B-cell-derived ALLs and non-Hodgkin's lymphomas.<br />
According to Dr. Topp, patients with refractory ALL have a dismal prognosis. Complete remission rates in this subset range from 17% to 45% with intensive chemotherapy, and treatment-related mortality rates range from 12% to 23%. "Even with the best chemotherapy currently available for these patients, such as FLAG/IDA [fludarabine, cytarabine, granulocyte colony-stimulating factor, and idarubicin], only 30% of patients will go into remission. Remission is then usually only of short duration, with a median of around 6 months," he explained.<br />
In the current study, patients had difficult-to-treat B-precursor ALL, and all had relapsed after induction and consolidation therapy once or twice, or had refractory disease. The majority of patients had undergone allogeneic stem cell transplantation in addition to other chemotherapy.<br />
After receiving blinatumomab, 9 of 12 patients reached the primary end point of CR or CR+; all 9 also reached the secondary end point of becoming MRD-negative or obtained molecular remission. Both CR and MRD were reached within the first cycle in responders, so it is "a precise and quick therapy," said Dr. Topp.<br />
"This is unusual in this particular patient group," he remarked.<br />
"This means there was a reduction in tumor burden of greater than 5 logs. This is very significant because the CR rate means a reduction of 1 log, but molecular remission equates to a reduction of 5 logs of tumor burden," he added.<br />
The duration of response remains unknown in this particular trial, and will be reported at a later date, Dr. Topp noted. However, he cited a study he was involved with that was published online May 16 in the <em>Journal of Clinical Oncology</em>, which investigated the effect of blinatumomab on MRD and duration of response. "We found patients who are still MRD-negative after 2.5 years. Extrapolating from those data to this trial, there may be patients who experience a very similar clinical course," said Dr. Topp.<br />
<br />
<br />
Very interesting Phase II trial for Pre B ALL which is a very difficult disease to treat.<br />

Schuchat said the number of girls receiving vaccinations has been disappointing, and there is hope that vaccinating boys will protect both young women and young men.</div><div style="padding-bottom: 10px; padding-left: 0px; padding-right: 5px; padding-top: 0px;"><br />

These results will be presented at the 2012 Gastrointestinal Cancers Symposium.</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">This test is usually used for patients with lymph node negative breast cancer.</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">Gene expression profiling explores the patterns of genes that are active in tumor cells. Studies suggest that gene expression may provide important information about prognosis or likely response to treatment in several types of cancer. For example, among selected women with early-stage breast cancer, the Oncotype DX breast cancer test has been shown to predict the likelihood of cancer recurrence and the likelihood of benefit from chemotherapy. As a result, the test has been added to medical guidelines for early-stage breast cancer.</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">A similar test became available for patients with Stage II colon cancer in 2010. Stage II colon cancer refers to cancer that extends through the wall of the colon but has not invaded lymph nodes or spread to distant parts of the body. Many patients with this stage of disease have good outcomes with surgery alone, and routine adjuvant (post-surgery) chemotherapy is not currently recommended for Stage II colon cancer. Chemotherapy may, however, be considered for Stage II patients with a higher risk of cancer recurrence.</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">Thanks cancerconnect.com</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;">This will be a great tool for patients with stage II colon cancer and will make the decision to administer adjuvant chemotherapy or not easier.</div><div style="background-color: white; color: #202020; font-family: Arial, Tahoma, Verdana; font-size: 12px; line-height: 18px; padding-bottom: 15px; padding-left: 0px; padding-right: 0px; padding-top: 0px;"><br />

<br />
In a double blind, placebo-controlled, phase 3 trial (the most accurate trials that doctors pay attention to), 1,873 patients were enrolled from 336 sites in the United States, Canada, South Korea and Japan. Researchers randomly assigned eligible patients — eligibility determined as previously untreated or incompletely resectable stage III or any stage IV ovarian cancer.<br />
<br />
At the conclusion of the study, patients who received bevacizumab with chemotherapy throughout demonstrated a longer median of progression free survival (14.1 months) compared with patients in the control group (10.3 months) and the bevacizumab/placebo group (11.2 months). <br />
<br />
This is certainly an option which may be entertained in patients with metastatic ovarian cancer.<br />

This is the result of a pre-planned interim analysis conducted by an independent Data Monitoring Committee (DMC) of the CORRECT (Patients with metastatic </span><u><span style="font-family: Arial; font-size: 1em;">co</span></u><span style="font-family: Arial; font-size: 1em;">lorectal cancer treated with </span><u><span style="font-family: Arial; font-size: 1em;">re</span></u><span style="font-family: Arial; font-size: 1em;">gorafenib or pla</span><u><span style="font-family: Arial; font-size: 1em;">c</span></u><span style="font-family: Arial; font-size: 1em;">ebo after failure of standard </span><u><span style="font-family: Arial; font-size: 1em;">t</span></u><span style="font-family: Arial; font-size: 1em;">herapy) trial. Per the recommendation of the DMC, the study has been unblinded and patients in the placebo arm will be offered treatment with regorafenib. In this trial, the safety and tolerability of regorafenib were generally as expected and did not show any new or unexpected toxicities. Data from the study are expected to be presented at a forthcoming scientific meeting. </span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">“These data are significant because they demonstrate that regorafenib increases overall survival in patients with heavily pretreated mCRC, an area of high unmet medical need,” said Kemal Malik, MD, Head of Global Development and member of the Bayer HealthCare Executive Committee. “We are extremely encouraged by the result of this analysis and we are hopeful about the potential of regorafenib to fill this unmet treatment need.”</span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Bayer will continue discussions with health authorities worldwide, including the European Medicines Agency (EMA) and the U.S. Food and Drug Administration (FDA) regarding next steps in filing for approval of regorafenib in the treatment of mCRC.</span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Bayer recently entered into an agreement with Onyx Pharmaceuticals, Inc. under which Onyx will receive a royalty on any future global net sales of regorafenib in oncology.</span><br />
<br />
<b><span style="font-family: Arial; font-size: 1em;">About the CORRECT Study </span></b><br />
<span style="font-family: Arial; font-size: 1em;">The CORRECT trial is an international, multicenter, randomized, double-blind, placebo-controlled study that enrolled 760 patients with mCRC whose disease has progressed after approved standard therapies. The study was conducted in North America, Europe, China, Japan and Australia.</span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Patients were randomized to receive either regorafenib plus best supportive care (BSC) or placebo plus BSC. Treatment cycles consisted of 160 mg of regorafenib (or matching placebo) once daily for three weeks on / one week off plus BSC. The primary endpoint of this trial was overall survival. Secondary endpoints included progression-free survival, objective tumor response rate and disease control rate. The safety and tolerability of the two treatment groups were also compared.</span><br />
<br />
<b><span style="font-family: Arial; font-size: 1em;">About Colorectal Cancer</span></b><br />
<span style="font-family: Arial; font-size: 1em;">Colorectal cancer (CRC) is a disease in which malignant (cancer) cells form in the tissues of the colon or rectum. The majority of cancers occurring in the colon and rectum are adenocarcinomas, which account for more than 90 percent of all large bowel tumors. </span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">CRC is the fourth most common cancer worldwide, with over one million cases occurring every year. The mortality rate from CRC is approximately half of its global incidence. The five-year survival estimate for CRC on average is 55 percent, but varies very much dependent on the stage of the disease (from 74 percent for patients with Stage I disease to only 6 percent for Stage IV patients). </span><br />
<br />
<b><span style="font-family: Arial; font-size: 1em;">About Regorafenib </span></b><br />
<span style="font-family: Arial; font-size: 1em;">Regorafenib is an investigational oral multi-kinase inhibitor of angiogenic, stromal and oncogenic receptor tyrosine kinases (TK). Regorafenib inhibits angiogenic kinases like receptors for VEGF which play central roles in angiogenesis. It also inhibits various oncogenic kinases including RAF, RET as well as stromal kinases such as KIT and PDGFR, thereby helping to stop the proliferation of cancer cells. Regorafenib has shown antitumor activity in preclinical studies by inhibiting tumor growth in multiple xenograft models via antiangiogenic and antiproliferative mechanisms. Based on these results, regorafenib is currently being investigated in clinical trials for its potential to treat patients with various tumor types. </span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Regorafenib is an investigational agent and is not approved by the United States Food and Drug Administration (FDA), the European Medicines Agency (EMA) or other health authorities.</span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Regorafenib was granted orphan drug designation by the FDA for the treatment of patients with gastrointestinal stromal tumors (GIST). Orphan drug designation aims to encourage the development of drugs involved in the diagnosis, prevention or treatment of a medical condition affecting fewer than 200,000 people in the country. </span><br />
<br />
<span style="font-family: Arial; font-size: 1em;">Regorafenib was granted Fast Track designation by the U.S. FDA for the treatment of patients with metastatic and/or unresectable GIST whose disease has progressed despite at least imatinib and sunitinib as prior treatments, as well as for the treatment of patients with mCRC who have progressed after approved standard therapies. Fast Track is a process designed to facilitate the development, and expedite the review of drugs to treat serious diseases and fill an unmet medical need.</span><br />
