January 25th, 2011. Thymidylate synthase and excision repair cross-complementing group-1 as predictors of responsiveness in mesothelioma patients treated with pemetrexed/carboplatin
Conclusions: In our series of carboplatin-/pemetrexed-treated MPM patients, low TS protein and mRNA levels were significantly associated to DC, improved PFS, and OS. Prospective trials for the validation of the prognostic/predictive role of TS in MPM patients treated with pemetrexed-based regimens are warranted.
January 12th, 2011. Retreatment with pemetrexed-based chemotherapy in patients with malignant pleural mesothelioma
In conclusion, re-treatment with PBC should be considered as second-line therapy in MPM patients achieving a durable (>12 months) disease control with first-line PBC. Further prospective evaluation of this therapeutic option is warranted.
January 2nd, 2009. Phase I and Pharmacokinetic Study of Pemetrexed plus Cisplatin in Chemonaive Patients with Locally Advanced or Metastatic Malignant Pleural Mesothelioma or Non–Small Cell Lung Cancer
Conclusions: Pemetrexed with vitamin supplementation was safe and well tolerated at higher doses than the currently established 500 mg/m2 + 75 mg/m2 cisplatin. Based on this study, the recommended dose would be 800 mg/m2 pemetrexed + 75 mg/m2 cisplatin. However, recent studies showed a lack of improved efficacy for 900 or 1,000 mg/m2 single-agent pemetrexed versus 500 mg/m2 and a lack of PK/pharmacodynamic exposure-response relationship for the pemetrexed/cisplatin combination across pemetrexed exposures corresponding to this dose range. Based on currently available evidence, we recommend retaining the established dose.
December 19th, 2008. Gemcitabine combined with oxaliplatin in pretreated patients with malignant pleural mesothelioma: an observational study
Conclusion: Pemetrexed-pretreated patients with progressive MPM may benefit from a consecutive chemotherapy with oxaliplatin and gemcitabine without significant toxicity.
December 2nd, 2008. Malignant peritoneal mesothelioma-Results from the International Expanded Access Program using pemetrexed alone or in combination with a platinum agent
Results: Response rates (95% CI) for PEM, PEM/CIS, and PEM/CARBO were 12.5% (3.5, 29.0), 20.0% (7.7, 38.6), and 24.1% (10.3, 43.5), respectively. Median survival for PEM was 10.3 months. One-year survival rates for PEM/CIS and PEM were 57.4% (95% CI: 10.3, 100) and 41.5% (95% CI: 4.6, 78.4), respectively, and were not available for PEM/CARBO. Anemia was the most common serious adverse event (6.4%). Neutropenia (34.6%) was the most frequent CTC grade 3 or 4 toxicity reported. Concluding statement: PEM with or without a platinum agent was both active and well tolerated in patients with peritoneal mesothelioma.
November 26th, 2008. Mesothelioma: treatment
There are few active cytotoxic drugs in this disease. Currently, based on two randomised trials, the most efficacious chemotherapy regimen consists in a combination of cisplatin and an antifolate agent, pemetrexed or raltitrexed.

November 26th, 2008. Comparison of semiquantitative fluorescence imaging and PET tracer uptake in mesothelioma models as a monitoring system for growth and therapeutic effects
Conclusion: Fluorescence imaging could be used to semiquantitatively monitor tumor size, whereas PET could be used to monitor tumor response to therapeutic treatments, and especially, FLT might be a good marker of the response to anti-folate chemotherapeutics.
November 14th, 2008. Outcomes with first-line platinum-based combination chemotherapy for malignant pleural mesothelioma: a review of practice in British Columbia
No difference is seen combining platinum analogs with gemcitabine or pemetrexed. Platinum-based doublets might represent a therapeutic ceiling for cytotoxic chemotherapy in MPM.

October 9th, 2008. Peritoneal Mesothelioma
To date there have been no universally accepted treatments for MPM. Unless referred to a specialty center, patients are routinely treated with pemetrexed and cisplatin which has been shown to increase survival in pleural mesothelioma.

October 2nd, 2008. Pemetrexed as second-line therapy for advanced non-small-cell lung cancer (NSCLC)
Pemetrexed, a multitargeted antifolate agent, has shown clear activity in several tumors, including mesothelioma and NSCLC. In a phase III trial, second-line treatment with pemetrexed demonstrated overall survival comparable to docetaxel, with a more manageable toxicity profile.

September 5th, 2008. Systemic Treatments for Mesothelioma: Standard and Novel
These include drugs targeted against the epidermal growth factor, platelet-derived growth factor, vascular endothelial growth factor, src kinase, histone deacetylase, the proteasome, and mesothelin. Given the progress made in recent years, there is reason to believe that more effective treatments will continue to be developed.

September 2nd, 2008. Recent advances in the treatment of malignant pleural mesothelioma
Vorinostat, a small molecule inhibitor of HDAC, which targets select members of class I and II HDACs, has shown early evidence of activity and is currently being evaluated in a randomized study for patients who progress with standard therapy for advanced mesothelioma. It is hoped that the HDAC inhibitors and other novel targeted agents will pave the way for improved outcomes for patients with this disease.

August 30th, 2008. Link] Goudar RK. Department of Medicine, Division of Hematology, Medical Oncology and Cellular Therapy, Duke University Medical Center, Durham, NC, USA. Abstract Malignant pleural mesothelioma is a resistant form of lung cancer, and its incidence continues to rise in Europe and Australia. Until recently, chemotherapy had not been shown to be effective in the treatment of this slowly progressive disease. In 2004, the combination of pemetrexed and cisplatin was shown to induce high response rates in MPM. This article reviews the published literature describing the development and testing of this therapeutic combination in mesothelioma, and examines in detail the key phase III clinical trial that led to the approval of pemetrexed by the US FDA. Ongoing research will further define the role of pemetrexed plus cisplatin in the treatment of MPM.

August 14th, 2008. Acute generalized exanthematous pustulosis after pemetrexed, and recurrence after re-introduction
Pemetrexed is an antifolate drug, approved for treatment of metastatic non-small-cell lung cancer (NSCLC) and malignant pleural mesothelioma (MPM). We present a case of AGEP caused by pemetrexed, and a recurrence of this eruption after re-introduction of pemetrexed despite use of corticosteroids.
July 22nd, 2008. Pemetrexed plus gemcitabine as first-line chemotherapy for patients with peritoneal mesothelioma: final report of a phase II trial
Conclusion: The combination of pemetrexed plus gemcitabine was active in patients with MPeM with a notably high incidence of neutropenia. Median TTPD and OS seem promising. This regimen may provide an alternative to standard therapies, especially for patients who cannot tolerate a platinum-based regimen.
July 18th, 2008. Pemetrexed
Addition of folic acid and vitamin B12 significantly reduced the toxicity of pemetrexed, especially hematologic toxicity and gastrointestinal toxicity. Pemetrexed is the expected agent for use in high risk patients, especially elderly or poor performance status patients.
July 3rd, 2008. Pemetrexed plus cisplatin or pemetrexed plus carboplatin for chemonaïve patients with malignant pleural mesothelioma: results of the International Expanded Access Program
Conclusion: This large EAP confirmed the activity of pemetrexed plus cisplatin and pemetrexed plus carboplatin in chemonaive patients with MPM, demonstrating clinically similar time to progressive disease and 1-year survival rates.
July 3rd, 2008. Single-agent pemetrexed for chemonaïve and pretreated patients with malignant pleural mesothelioma: results of an International Expanded Access Program
Conclusions: In the present expanded access program, single-agent pemetrexed demonstrated promising activity in MPM in both chemonaïve and pretreated patients, with TTPD of 6.0 and 4.9 months, respectively, 1-year survival >or=54.7%, and mild hematologic toxicity.
