    Ok, cya downstream...
    JMO, but I think you are premature.
    I'll keep future positive results off the MB...
    ...and limit my posits to misguided rumor, mindless conjecture, and purposeless innuendo.
    Just for you, I'll not quote any positive sources here again...
    Regardless of credentials, academic affiliations, or medical prestige...
    Be good...

    I believe the CoBRIM P3 poster presentation will be web-available concurrent with the oral presentation on the 29th. There are also a couple of Cabo poster presentations that have been accepted. I don't expect anything to shake it up. I think one is a Dr Andrea Apolo GU poster - probably bladder ca. She's worked with Cabo for quite some time, and her NIH inferences are worth following. In addition, she's pretty easy on the eyes...
    If Cobi is well-received at ESMO, I expect an update on the Roche/EXEL partnership...

    CoBRIM has met its primary endpoint of statsig PFS, and will present 9/29/14 at ESMO.
    OS survival data will likely be immature, but I'd expect a small preview based upon KM projections.

    RCC

    For continuity sake, here're the basics of METEOR design from the May '13 PR:
    "METEOR is an open-label trial of cabozantinib in patients with mRCC that is being conducted at up to 200 sites in up to 26 countries. The trial is expected to enroll 650 patients with clear cell RCC who have received and progressed on at least one VEGFR-TKI. Patient enrollment will be weighted toward Western Europe, North America, and Australia, and patients will be stratified based on the number of prior VEGFR-TKI therapies received and commonly applied RCC risk criteria developed by Motzer et al. Patients will be randomized 1:1 to receive 60 mg of cabozantinib daily or 10 mg of everolimus daily. No cross-over is allowed between the study arms.
    The primary endpoint is progression-free survival (PFS) and the secondary endpoint is overall survival (OS). Exploratory endpoints include patient-reported outcomes, biomarkers, safety, and pharmacokinetics. PFS is an established acceptable endpoint for RCC clinical trials and has been used to support approval of sorafenib, sunitinib, everolimus, axitinib, and pazopanib in this indication.
    Based on available clinical trial data, the primary endpoint assumes a median PFS of 5 months for the everolimus arm and 7.5 months for cabozantinib arm. This provides for a hazard ratio (HR) of 0.67 and 90% power and requires 259 PFS events among the first 375 patients randomized. The secondary endpoint assumes a median OS of 15 months for the everolimus arm and 20 months for the cabozantinib arm. This provides for a HR of 0.75 and 80% power and requires 413 events."

    "Is there anything in that data that could sway regulators?"
    This is the question that will carry us to year's end, and there is no simple answer. There is great potential for Comet-2 to deliver compelling pain response data, which - though an approvable endpoint...may not be an affordable endpoint - given the comparably cheap affordability of palliative opioid meds. I would take it at face value that the decision to close Comet-2 recruiting mirrors the lack of confidence EXEL management has in a successful sNDA regulatory filing at this time. If push comes to shove, and Comet-2 delivers statsig pain data and enough supportive hrQOL benefit data to constitute a filing, I expect it to be a hugely controversial issue - loaded with argument from every quarter of the industry.
    On the less conspicuous upside, I expect to see a future filing with the NCCN for off-label salvage Cabo prescription in CRPC, but such a filing necessarily comes with the downside of negated marketing value in that indication.

    "...does the pod cast content infer any difficulty for the METEOR...?"
    No. Different disease, different patient group, with much different pretreatment regimens. Each cancer indication must be considered based upon its own merits, and cross-referencing trial data -especially between indications- should be avoided. Here's the ASCO 2012 data mostly responsible for METEOR design:
    "Tumor Regression. Objective evidence of tumor regression was observed in 19 of 21 patients (90%) with ≥1 post-baseline assessment. Best overall response was determined per RECIST criteria with 7 of 25 patients (28%) showing a confirmed partial response (PR). Importantly, PRs were observed in heavily pretreated patients, including 3 patients with 2-4 prior systemic therapies, and 2 patients with 4 prior systemic therapies. Thirteen additional patients (52%) had stable disease (SD) as their best response, and only a single patient (4%) demonstrated evidence of primary refractoriness to cabozantinib with a best overall response of progressive disease. The rate of disease control (PR + SD) at week 16 for all 25 patients is 72%.
    Progression-Free Survival, Overall Survival, and Treatment Duration. Kaplan Meier estimate of median progression-free survival (PFS) is 14.7 months (95% CI, lower limit 7.3 months – upper limit not reached). Median overall survival (OS) has not yet been reached after median follow-up of 14.7 months. The estimated 1-year survival rate is 60%. Seven patients remain on study and progression free with treatment durations ranging up to 21.8+ months."
    In CRPC, Cabo displays dramatic efficacy (and perhaps incomparable) in the wake of prior treatment with docetaxel and AR modification in a very difficult to treat population. In mRCC, Cabo displays dramatic efficacy in the wake of prior treatment with up to 3 lines of therapy, including sorafenib, sunitinib, and everolimus - essentially, another salvage group with extremely limited treatment options. Statsig PFS looks doable.

    Of course I am paraphrasing here, but the brunt of the Antonarakis commentary is this:
    Despite cabozantinib's compelling and apparently beneficial impact on the bone micro-environment in mCRPC, the therapeutic window is likely too narrow to display a measurable impact on survival in this patient population. Follow-up has shown 4 months DOR in both 100mg and 40mg cohorts.
    You really need to find a venue to download it and listen to it in it's entirety. It's approx 9 minutes long, and I can't do it justice other than to convey that IMO it is not favorable news, though it's impact on palliative therapy (re:Comet-2) remains to be seen.

    I suspect this research is part of the initiative to explore and define anti-VEGF resistance mechanisms. Cabo's MOA is not completely understood, but it's VEGFR2 inhibitory capacity is well-documented. Fitting together all the puzzle-pieces of cell-signaling crosstalk, feedback, and synergy will create the map that will fuel biomarker-guidance of the future, and perhaps create the sequenced course of therapeutics to mitigate treatment-induced resistance.
    In addition, all the mentioned TKI's in this study have shown notable responses of progression free survival in ThyCa. Optimizing that PFS to translate directly into statsig survival benefit might be an additional study goal here. Cabo's notable fast-acting and recognizable early response signature makes it a great research tool. Extending Cabo performance in Thyca to other cancers may prove difficult as a multi-targeted TKI like Cabo plays to a great number of disease drivers, some of which may provide benefit...some of which may induce off-target toxicities, thereby reducing measurable therapeutic benefit. Quite a balancing act...
