Thursday....October 14th..2010

Linda has "perked" up significantly with the acceptance in a clinical trial.....all doctor visits and tests are in place with the first infusion to begin next Thursday....

For more information on the clinical trial....

Other things...good weather today....final stretch of fencing about done....got to see game 3 of the seaon for the Tampa Bay Lightning tonight..which they won..they have won the first three games of the season...Mrs. Wood cooked dinner tonight...tasty calzone....good for her....


If you can understand below..Linda is the "wild wild" they talk about...70% with 70% success rate.......she is in the Phase 2 clinical trial....


Synta expands STA-9090 Phase 2 clinical trial in NSCLC
13. September 2010 09:24


Synta Pharmaceuticals Corp. (NASDAQ: SNTA), a biopharmaceutical company focused on discovering, developing, and commercializing small molecule drugs to treat severe medical conditions, today announced that it was expanding its Phase 2 clinical trial of STA-9090 in patients with Stage IIIB and Stage IV non-small cell lung cancer (NSCLC) from up to 69 patients to up to 146 patients based on encouraging activity observed in the first stage of the two stage clinical trial. STA-9090 is a potent, second-generation, small-molecule Hsp90 inhibitor, with a chemical structure unrelated to the first-generation, ansamycin family of Hsp90 inhibitors (e.g., 17-AAG or IPI-504).

"This NSCLC trial is enrolling patients into cohorts defined by the mutational status of key genes in order to identify cancer types especially responsive to STA-9090," said Vojo Vukovic, M.D., Ph.D., Senior Vice President and Chief Medical Officer, Synta Pharmaceuticals. "In the first stage of this trial we have seen exactly that; patients with EGFR and KRAS wild type, representing over 70% of all NSCLC, have shown a high disease control rate, over 70%. This early signal, combined with the objective responses seen following treatment with STA-9090, is very encouraging, particularly as the patients have been heavily pretreated and are refractory to many standard of care drugs. Also encouraging is that STA-9090 continues to be well tolerated at the 200mg/m2 once-weekly schedule, without the serious hepatic or ocular toxicities observed with other Hsp90 inhibitors. Based on these findings, we worked closely with investigators, modified the protocol, and expanded the trial in order to confirm and further characterize the observed activity in this group of patients. We expect to report on additional results from this trial, as well as plans for future trials in lung cancer, later this year or early next year."

Synta also announced that the Phase 2 trial will allow for the first focused evaluation of STA-9090 combination therapy in NSCLC. An additional cohort was created to allow certain patients to receive treatment with both STA-9090 and docetaxel. Clinical and preclinical results provide a strong rationale for combining taxanes and Hsp90 inhibitors, with the potential for synergistic activity.




STA-9090
Hsp90 Inhibitor


Program Overview
About STA-9090
STA-9090 is a potent, second-generation, small-molecule heat shock protein 90 (Hsp90) inhibitor, being developed for treating multiple solid tumor and hematologic cancers.

STA-9090 was discovered and developed internally at Synta and has a chemical structure unrelated to the first-generation, ansamycin family of Hsp90 inhibitors such as 17-AAG or IPI-504. In preclinical studies, STA-9090 has shown potency up to 100 times greater than the first-generation Hsp90 inhibitors as well as activity against a wider range of kinases. In in vitro and in vivo models, STA-9090 has shown potent activity against a wide range of cancer types, including lung, prostate, colon, breast, gastric, pancreatic, gastrointestinal stromal tumors (GIST), melanoma, AML, chronic myeloid leukemia, Burkitt's lymphoma, diffuse large B-cell lymphoma, and multiple myeloma - as well as potent activity against cancers resistant to imatinib (Gleevec®), sunitinib (Sutent®), erlotinib (Tarceva®), and dasatinib (Sprycel®).

Mechanism of Action
STA-9090 potently inhibits Hsp90, a chaperone protein required for the proper folding and activation of other cellular proteins, particularly kinases. Many of these "client proteins" of Hsp90—such as AKT, BCR-ABL, BRAF, KIT, MET, EGFR, FLT3, HER2, PDGFRA, VEGFR—have been shown to be critical to cancer cell growth, proliferation, and survival and are the targets of clinically validated and approved cancer drugs such as Gleevec, Avastin, Herceptin, Sutent, Nexavar, Tarceva, and Erbitux. In preclinical studies, inhibiting Hsp90 causes the degradation of multiple client proteins and leads to cancer cell death. Because mutated kinases which no longer respond to treatment with kinase inhibitors remain dependent on Hsp90 for their activity, inhibiting Hsp90 offers the potential for treating cancers that have become resistant to targeted therapies such as kinase inhibitors. We believe that inhibiting kinases indirectly, by disrupting the chaperone activities of Hsp90, provides two advantages: first, a means to simultaneously attack multiple cancer-promoting kinases; and second, an ability to kill tumor cells with mutated kinases that have lost responsiveness to a direct kinase inhibitor.

So pleased for you, Linda, that you are finally able to participate in the clinical trial. It sounds very promising! We are rooting for you and Dave, too. We still want to get over to see you, but are still dealing with health issues -- certainly nothing like yours! Love and all the best to you both. Shari & John

Hi you two. Just droped in for a catch-up. Good news about the clinical trial. I always am impressed by you both.
Much love from us.

This is great news. So glad you are moving forward with a plan. Isn't it great when a plan comes together.
