Arthritis associated with anti-PD1

Here's a bit from a post I made in September regarding my check-up at Moffitt, then 15 months after my last dose of Nivo and 45 months after starting my trial:

    'Sadly, as it has been for some time, the questions I have, have no absolute answers. I, and my fellow ratties, ARE the answer.  But, I asked a few none-the-less.  The one of most importance:
"Having completed anti-PD1, is my immune system permanently changed, or was the change temporary?"
After some discussion and recognition that no one really knows the answer to this...the answer was:
"Yes, it is most likely that your immune system has been altered permanently via your central memory T cells."
     The good news, if this is indeed the case, is that, theoretically, my memory T cells will be around for a good while and continue to kill off any horrid little melanoma cells fluttering about. On the down side, a forever changed immune system could continue to put me at greater risk for immune stimulated disease processes...but what's a girl to do?  And mostly...time will tell all.'

My answer is, "Soooo very changed indeed!"  Given the way immunotherapy works, that is the hope.  But, it is not without issues.  Personally, my difficulties have been minimal compared to what folks have dealt with on and post ipi, and even mild compared to what some ratties have experienced on anti-PD1.   However, events that I am certain are side effects of the treatment I received continue to this day.  The weird thing about them...or more likely, about me!!! that I never see them for what they are at the start.  It's kind of like living with an unstable person.  You're just kind-of rolling along, thinking, "Whew, we're doing pretty well here.  Everything seems cool."  When apropos of nothing, the request, "Pass the potatoes, please." has a certain tenor, a tenseness, a harsh screech, hanging, just under the surface.  And you know...  Shit!  Here we go again.

For instance, my last/current tadah~  Got a bit of a cold, nothing terrible, from one of my critters at work.  As per my usual, such a thing flared up my asthma a bit, that's a norm for me for my whole life.  So, no worries.  The nurses ask why I am limping at work.  I reply, "I don't know.  I think I must have twisted my hip funny putting down some mulch for a friend."  An activity that I had participated in just a few days before. Then, I realize,"Man, this cold weather sure has my skin dry and itchy!"  Ok, then, wow, "Did I bite my tongue?  I don't remember doing that.  Wait a minute!!!"  And, sure enough...a peek in the mirror shows lesions all along the side of my tongue, red and angry.  By the next day they are along the other side as well.  The itchy skin is full blown welts in places and all the residual granulomas from my vaccine injections are red, warm and swollen.  The fact that my wheezing has continued, and even worsened, over the past four weeks despite aggressive nebulizations for my asthma...makes me pretty confident that I am dealing with a mild pneumonitis, much like what would happen with some regularity after my anti-PD1 infusions.  Add to that the fact that my joint aches have roamed like the Greek humors from right hip to left ankle, right knee, left wrist and any mixture of the above.  There has been no putting down of mulch.  No strain.  Just me.  Post anti-PD1 with my weird T cells.  My personal theory is that whenever I get a mild viral process, and perhaps sometimes even when I don't, my T cells go a bit nuts and cause various autoimmune problems.  Here is what  more important folks have to say:

Arthritis and Tenosynovitis Associated with the Anti-PD1 Antibody Pembrolizumab in Metastatic Melanoma.  Chan, Kefford, Carlino, et al.  J Immunother.  2014 November 20.

"We report the acute onset of polyarticular inflammatory arthritis in 2 patients receiving the immune check-point inhibitor, pembrolizumab....after 14 and 11 months of therapy, respectively....Good symptomatic control was obtained with bisphosphonates (drugs to prevent bone loss like Boniva and Fosamax) and salazopyrin (Sulphasalazine - an anti-inflammatory), avoiding use of T cell immunosuppressants.  These cases raise important questions on whether anti-PD1 therapy allows preexisting autoimmune  T cell clones to escape tolerance by suppressing regulatory T cells or whether they allow autoimmunity to develop de novo.  These conditions heighten our awareness of complications associate with the use of these agents..."  

So...basically...these folks are noting other patients who have developed joint problems much as I have. Their question is.... Did I (and these peeps) have the propensity, though unrevealed prior to anti-PD1 therapy, for an arthritic process?  OR...did anti-PD1 cause the arthritic process on its own?  As more folks take these drugs, I think more examples of autoimmune problems not only while on anti-PD1, but in the months and years(!!!) afterwards - arthralgias as well as issues related to derm (itching), gastro (mouth ulcers, colitis), pulmonary (wheezing, pneumonitis, strange spots on CXR) - will be noted.  Of course, to be able to sit here kvetching about my little aches and itches 55 months out from Stage IV melanoma and 17 months post a 2 1/2 year trial of Nivo makes me incredibly lucky indeed.

Oh, on a lighter note!!  I'm a good 12 hours into my post-Thanksgiving/pre-New Year's CLEANSE!!!!  Yep!  Decided good ol' Gwennie and other celebs who like to publish the contents of their intestinal tracks (or absence of contents in that area) had the scoop on health and beauty!  Why should I pass up such a good thing?!  NOT!!!!  In an episode of what I am certain was an event similar to those noted above, several months ago, I got a gastro bug that was going around the critters in the office.  A little headache ( did last two weeks), some vomiting and a little diarrhea....turned into 12 hours of profusely bloody diarrhea.  So, B, Tammy B, Weber, and now my gastroenterologist (Yes, Virginia....I am rapidly acquiring EVERY sort of doctor now!!!) have gone into complete panic and melt-down mode (all at different times, thank goodness....SHEW, you people wear a girl out!!!!) and tomorrow at the ever lovin' BUTT CRACK of dawn (6:40am!  W.T.H. people??!!)...and BOY!!!! will be BUTT CRACK fo sho!!!...I will be having a colonoscopy.

I'll be lettin' y'all know how that all comes out!!!  I know you can't wait to hear!!!

#Throwback Thurday/Thanksgiving!!!!

When I say I've been cooking forever, I'm not kidding!!!  I was three in this pic and I still love me some pie!!!
If you want to make your own pie dough, be my guest...but unless I'm making a tart that is savory or one that needs to stand up to special flavors, I just roll with the store bought version...though I am partial to this style.
Roll it out a little more after a sprinkle of flour.... 
And place it in your dish...
For any berry pie...the basic recipe is:  3 cups berries, 4 tablespoons flour, 2/3-1 cup sugar depending on taste and sweetness of your berries, butter to dot over the top of the fruit...and your pastry.  I do like to add some lemon zest to blueberries or blackberries as you see here.  Nutmeg and cinnamon are nice additions with peaches and apples.
Mix.  Then place fruit mixture in your pastry lined dish.  Use a brush or your finger to dampen your pastry edge with water...that will be your 'glue' when you put on either a solid pastry "lid" or the lattice top shown below....
For a lattice top, roll out the other half of your dough as you did for the bottom, but afterwards, cut into strips.
Choose strips of appropriate lengths and smish their top edge into your water dampened edge of the bottom pastry. 
You could just lay pieces across one way and then across in the other, but I think it is fun to actually layer mine in an alternating fashion!!! 
After you have finished creating the lattice with your strips, make sure all ends are pressed into the sides of the bottom layer of pastry.  Trim off excess by running a knife around the edge of your dish and crimp it all together using your fingers or mash with the tines of a fork. AND....if you're like me and tend to forget to dot your top with can always squich it in the spaces between your lattice!  Handy, right?
You can then bake in a 400 degree oven for about 40-50 minutes, until the filling is bubbling and the pastry nicely browned, as is.  But it does protect the crust on the outer edge from getting too browned if you place a little foil collar around the edge.  You can remove it, oh around the last 10 minutes of cooking.  And using a brush to apply a little milk or egg wash to the pastry edges makes them shiny and a bit more tasty, especially if you add a sprinkle of sugar or cinnamon sugar like a special glitter topping! If you want a solid top to your pie - just lay that pastry piece on top and attach and finish the edges per previous instructions.  Do remember to add some slits (as simple or as fancy as you like) to provide vents for the steam...else-wise your pie might suffer a blow out!
No matter the style pie you choose, there will always be a little remnant of dough.  Ball it all back together, roll it out and make a tart!!! 
Fill with raisins and cinnamon sugar, blueberries and lemon curd, or any preserves you have on hand, dot with butter, fold over! 
Press edges together after they are dampened with water, crimp, and make your poke holes. 
After baking with the big pie for oh, about 15-20 minutes, depending on how big, thick or the sort of filling you put now have a snack to enjoy ahead of time or a little tart for breakfast! 
Ta dah!!!!  
Enjoy!!!  Happy Thanksgiving.  May there always be pie!!!  Love - c

For Kim...

Yup!!!  Surprised you didn't I?  Just wanted to let you know that I appreciate your reading of my meanderings, laughing at my jokes, passing over things that don't mean that much to you...yet coming back for more on another day, and sharing YOUR thoughts about MY thoughts!!!  THAT is a gift my friend!  A real gift.   I appreciate it and you...everyday.

I know there are many other faithful readers out there.  Some of you come here to find the information you need about melanoma for yourself or your loved one.  Some of you read because of an interest in me.  Some people land here for rather strange google-ing "Black Silky Chicken" (Been there, done that myself...hope my recipe helped cause there ain't that much out there on that one!!!!) and recently "another form of Botox"!  I'm sure my suggestion that the 'numbing' process for the halo application was the new wave in beauty treatments didn't help!  Or, at least I hope it didn't!!!

There are those whose role in my life would imply that they SHOULD read and comment, but purposefully choose not to.  I could focus on that.  It is rather bizarre, overwhelming, and sad.  But, to focus on that would do no good.  It would also negate all the beauty that has come my way because of those who choose to share...their lives...with me...the good and the hard.  Jonathan and Francoise, Lucy and Sue, Elaine, PJ, Eric, Steven, Jeanne....and so many more.  Friends from afar, now friends in my heart.  There are friends of my dear again....Terrie, Terri, David and the rest of you...reconnected...making me whole.

And, there are those of you I will never know...almost 150,000 peeks all together....from all over the U.S., the U.K., France, Turkey, China, Russia, Ukraine, Canada, Australia, Belgium, Germany, Spain, Netherlands, Finland, Poland, India...I wish you well.  I hope I helped.  I hope you smiled.

There are my faithful soldiers.  My rocks.  My battalion.  Ready at a moment's notice.  Your love, the armor you provide....immeasurable.  There are no words.  

So, Kim.  You make my work load lighter.  You make my day brighter.

Happy Thanksgiving.  For Kim...and all of you...I am thankful.  Love - c

Data on BRAFi combo's and effects of ipi before and after

Combined Vermurafenib and Cobimetinib in BRAF-Mutated Melanoma. 
Dreno, Atkinson, et al.  N Engl J Med 2014 September

Phase 3 study.  495 patients, previously untreated with unresectable BRAF V600 mutated melanoma got either vemurafenib and cobimetinib or vermurafenib and placebo.

Vermurafenib and Cobimetinib
Vermurafenib and placebo
Progression free survival
                 9.9 months
                  6.2 months
Complete or partial response
Complete response
Overall survival at 9 months

Combined BRAF and MEK inhibition versus BRAF inhibition alone in Melanoma.
Long, Stryakoviskiy, et al.  N Engl J Med.  2014 September.

Phase 3 trial.  423 BRAF V600 of V600K mutation melanoma patients with unresectable Stage IIIC or  Stage IV disease.

Dabrafenib and Trametinib
Dabrafenib and placebo
Progression free survival
                 9.3 months
                  8.8 months
Overall response at 6 months

Combined Dabrafenib and Trametinib in patients with BRAFV600 mutant melanoma experiencing progression with single-agent BRAF inhibitor.
Johnson, Flaherty, Weber, Infante, Kim, Hamid, Sznol, Sosman, Daud, et al. J Clin Onc, 2014 Oct

Phase I/II study.   Group B = 26 patients treated with dabrafenib and trametinib after disease progression with BRAFi before study enrollment.  Group C = 45 patients treated with dabrafenib and trametinib after progression on dabrafenib monotherapy as cross over treatment.

Group B
Group C
Overall response rate
Progression free survival
Treated with Dabrafenib less than 6 months – 3.9 months
Treated with Dabrafenib more than 6 months – 1.8 months
      3.6 months
Overall survival
Tx more than 6 months – 26%
Tx less than 6 months – 0%
      11.8 months

Conclusion:  Dabrafenib plus trametinib has modest clinical efficacy in patients with BRAF i resistant melanoma.  This may be a therapeutic strategy for patients who previously benefited from BRAF inhibitor monotherapy for more than 6 months but demonstrated minimal efficacy after rapid progression with BRAFi therapy.

Characteristics of pyrexia in BRAFV600E/K metastatic melanoma patients treated with combined dabrafenib and trametinib in phase 1/2 clinical trial.  Menzies, Ashworth, Flaherty, Weber, Infante, Hamid, Sosman, Daud, et al.  Ann Oncol. 2014 November

Pyrexia = fever, in this case defined as a temperature at or greater than 100.4 or related symptoms.
59% of patients developed pyrexia.  24% had symptoms with recorded increased temp.  Median onset of first pyrexia was in 19 days, median duration of 9 days.  Pyrexia patients had a median of two pyrexia events, but 21% had three or more events.  No baseline features predicted pyrexia and it was not associated with clinical outcome.

Objective responses can be obtained by CTLA-4 inhibition in metastatic melanoma after BRAF inhibitor failure.  Schreuer, Chevolet, et al.  Melanoma Research.  2014 November

64 patients with unresectable Stage III/IV BRAF V600 mutant melanoma.  33 had been treated with BRAFi before ipi.  31 patients were treated with ipi first.  In BRAFi first patients:  three complete responses and 6 partial responses, with median overall survival of 10 months from start of ipi therapy.  Ipi first patients:  no complete responses and 4 partial responses, with median overall survival from start of ipi therapy was 12.3 months.  Response rate did not differ significantly between the groups.

So....not really new news.  Combo's offer better results.  Fever occurs often and can be worse in the combos, but no patient specific features can predict who develops fevers and fever has not been associated with outcome, for better or worse.  In the final study, for all their numbers, there was apparently no statistical difference in response whether you took BRAFi followed by ipi or vice versa.  Best wishes - c

Commentary - Why checkpoint inhibitors need help and a little push for SCIB1

Commentary by Richard Goodfellow, June 2014, Scancell

Despite all the advances in melanoma treatments in the past 4 years, we're still not quite there yet!  I thought this essay was interesting...though you must keep in mind that the author is the chief executive officer of the company that makes SCIB1.  However, Bent has always held that dendritic cells will prove essential in really understanding and treating melanoma.

Excerpts:  "Checkpoint inhibitors enable the host immune system to resume its ability to recognize, attack, and destroy cancer cells.  Ipilimumab was the first.  Drugs blocking PD-1 and its ligand PD-L1 are in advanced trials.  However, checkpoint inhibitors cannot work...if the patient fails to mount an adequate immune response or if the tumor evolves so that is it no longer recognized by the pre-existing immune response."

"[Anti-] PD-1 drugs are being combined with ipi, tyrosine kinase inhibitors (sunitinib and erlotinib); with anti-CD27 antibody varlilumab; and BRAFi [to try to answer the lack] though side effects are often an issue with these combos."

"Taking the brake off T cells with checkpoint inhibitors whilst simultaneously pressing the accelerator using active immunotherapies is a logical next step...  Vaccines can stimulate 'de novo' immune responses, but until recently, none of the vaccines...have been able to produce potent T cells with the power and specificity to recognize and kill tumor cells.  Peptides and MAGE vaccines failed to show any advantage.  A phase 3 study of a virus encoding GM-CSF has shown  some promising results, but the patient must have accessible tumors."

"We would argue that this advantage can be obtained by using the power of dendritic cells, the 'generals of the immune response army'.  Our first product, SCIB1, is a DNA plasmid encoding an antibody with four melanoma-specific T cell epitopes grafted into its structures.  We use eletroporation (the use of electrical fields to increase DNA drug delivery efficiency by up to 1000 fold compared to conventional injection) in conjunction with IM injection to deliver SCIB1 to patients.  This results in the direct uptake of DNA into cells and also enhances the immune response by targeting the expressed hybrid antibody to dendritic cells via the CD64 receptor."

"Data from a Phase 1/2 clinical trial of SCIB1 in patients with advanced melanoma has shown high immune response rates, evidence of prolonged survival and tumor destruction with a benign side effect profile.  Median survival time in patients with Stage III/IV disease is now 30 months since patients entered the study.  Patients with resected Stage IV disease are all still alive 19-41 months since tumor removal.  This compares favorably with published survival rates for patients with resected disease where 50% of Stage IV patients usually die within 21 months of surgery."

Hmmm...  I haven't seen any published research data for SCIB1 yet.  Most of the pr...IS pr...being put out by the company or other pharma investments firms.  But....the trial is real, though only in the UK at this's the link:

Link to clinical trial with SCIB1  

Would love for this to hold the key!  We'll see what happens! - c

Skin stuff with Anti-PD1

I have certainly had weird skin things during and after being on Nivo!!!  Of course weird skin thing numero uno was melanoma!!!  Much as we have with ipi, as more folks take the anti-PD1 drugs, we will find out even more things about their side effects and how to deal with them.

Lichenoid dermatitis in two patients with metastatic melanoma treated with anti-PD1 therapy.
Joseph, Goedjen, Gordon, et al.  Cancer Immunol Res. 2014 Oct 6.

The "two most common side effects of anti-PD1/PDL1 therapies include rash and [itching] occurring in about 20% of patients.  While the rash is generally attributed to be immune mediated, the exact mechanisms of the rash remain unclear....We report two cases of lichenoid dermatitis [A scaly, itchy rash...resembling eczema or psoriasis and can be purplish in color.]  in two patients treated with MK-3475 that were characterized with marked T-cell infiltrates with few PD-1 positive cells.  Both patients were taking lisinopril [An ACE inhibitor used to treated increased blood pressure and congestive heart failure.], an agent associated with lichenoid reactions, however, neither had a rash prior to starting MK-3475. Both rashes were relatively mild allowing treatment to continue and responded to topical steroids.

Just for fun...crazy wonderful skirts!!!

I made some rather simple summer dresses, but decided to jazz things up with some crazy skirts!!!

Loved this material so much (Though there were those who said, as I proudly displayed this material after purchase, "You would never wear that!" How wrong they were. How little they know me!) that I had the bright idea to widen the A of the a-line skirt pattern I was using!!

Turns out, I am NOT ready for drafting my own patterns!!!  I looked like a puff butt oompa-loompa!!!!  But (no pun intended) after adding a pleat on either side, per Rosie's advice, I calmed the bubble!!!  Another sad fact.  I worked REALLY hard to match these polka dots!!!  Hmmm......

Have some minor concerns about the appearance of some sort of dinosaur tail (Is it a stegosaurus???) going up the rear.....but, what's a girl to do?  On the good is stitched together beautifully (if I say so myself!!!) with completely finished insides and I am really happy with the end product.  Also on the good side...though not at the time!!!  My serger ran out of thread in one bobbin in the middle of this production...thereby FORCING ME...yes, to learn to thread the sucker...which...I YAY!

Simple A-line (the pattern I probably should have stuck with!!!) but done up in wonderful wines of the world!  And, YES!!!  The sides and rear line up perfectly on this one!!!  I told B this one was perfect for a trip to France...or a wine tasting party at the very least!!!
Sante'! -c

Sargramostim ~ aka GM-CSF or leukine

Sargramostim, GM-CSF (granulocyte-macrophage colony stimulating factor), leukine, oh my!!!
With the report in HealthDay News breaking Nov. 4 and the actual study:  Ipilimumab plus sargramostim vs ipilmumab alone for the treatment of metastatic melanoma:  a randomized clinical trial  (Hodi, Lee, McDermott, et al.)  being published in JAMA on the fifth....questions on melanoma blogs and forums have gone through the roof!!!'s my best interpretation of what it all means.  First of all, let's back up a step!  Yes, the magical "sargramostim" is the same thing as GM-CSF, leukine and used in OncoVex.  It is an immunostimulator used most often to help grow new white cells after a bone marrow transplant or when they have been depleted by conventional chemo in diseases like leukemia.'s what I noted before in a post about the intralesional therapy OncoVEX: 

  "OncoVEX is a 2nd generation herpes virus embedded with GM-CSF...a substance that causes the body to make more white cells. (GM-CSF can be given to premature babies and leukemia patients with low white cell counts to help build them back up....and reverse immune suppression.) But, in OncoVEX, it is thought to only replicate in the tumor cells.  The white cells produced in the process kill off the tumor cells.  In a phase 2 trial reported in 2012, 20% of patients achieved a complete response and 28% gained an overall response.  92% of the responses were durable to at least 6 months, and the majority were ongoing with a range of 18-40 months.  Responses were found in patients with all stages and systemic tumors were eradicated in some patients."'s where Ribas and Weber discussed T-VEC vs GM-CSF and an abstract of a study that used GM-CSF and IL-2 as an injectable therapy

  Ribas:  ...a randomized trial of an injectable virus called T-VEC compared with granulocyte-macrophage colony stimulating factor (GM-CSF).

Weber:  ...the responses were 16% vs 2%.  Obviously you don't expect any responses with GM-CSF, so 2% would be essentially zero.  A 16% response rate overall in a patient with injectable local-regional disease plus systemic disease is pretty modest....

Tumor response and patient survival after intralesional therapy with low-dose GM-CSF and IL-2 in metastatic and primary cutaneous melanoma:  An exploratory study.  Elisas & Sharma

Patients with dermal and subdermal mets, no matter the extent of their disease or previous therapy, were given intralesional GM-CSF once a week for 4-6 weeks. If no complete clinical response was noted at the injection sites, they were then given intralesional IL-2 for the same length of time. Results:  4 patients with more than 126 small in-transit mets, each lesion measured a few mm to up to 1 cm.  All had a complete response confirmed pathologically 6-8 weeks after cessation of therapy, with disease free survival of 37-54 months.  Another 3 patients with large sclerotic skin lesions failed to respond to either cytokine.  One of 2 patients with distant mets who also had palpable subdermal tumors had complete response of all mets. This patient is alive and disease free for over 48 months.  Conclusion:  [After examination of the tissues resected after treatment...] Intralesional therapy seemed to utilize the tumor site as a source for tumor-specific antigens giving rise to autoimmunization with strong antitumor response...

Clearly, this drug is not unknown to oncology or even melanoma has been used as a control, combined with IL-2 and with a viral vector as an injectable therapy.  The story now is that Hodi et al., wanted to see if, when given systemically WITH ipi, would the immune stimulating effects of GM-CSF boost the patient's response to ipi???  A randomized clinical trial with 245 stage III or IV unresectable melanoma patients (12/2010 - 7/2011) were given either ipi at 10mg/kg plus sargramostim 250ug subcutaneously or ipi alone.  RESULTS:  Median OS for combo was 17.5 months vs 12.7 months for ipi alone.  1 year survival for combo was 68.9% vs 52.9% for ipi. PFS was only 3.1 months for both groups.  Grade 3/5 adverse events occurred in 44.9% of the combo group but even more frequently in the ipi only group at 58.3%.
So....GM-CSF decreased side effects when combined with ipi and resulted in longer overall survival, but provided no additional benefit in progression free survival.

In Reinberg's report in HealthDay, he indicated that Dr. Doris Day (I know!!!  Her parents didn't like her!!!) had a rather positive view of the results while Hodi (lead researcher in the study) didn't "know whether starting combination therapy before melanoma spread will improve survival."  Reinberg concluded his report with a quote from Dr. Mario Sznol, "Overall, these are interesting results..., but the field has moved so quickly, that it may be difficult to follow up..." Noting also that pembro and nivo alone will probably be more effective and less toxic.  Finally, Sznol stated, "So these results, even if confirmed, are not as important as they would have been several years ago."

My Take:
  • Yes, I think here, as with all immunotherapies, we've learned enough to know that starting them sooner, rather than later, with the least tumor burden possible, is better.  How much better would this turn out to be?  We don't know.
  • Nobody is giving ipi at 10mg/kg least not in anything other than a clinical trial.  And even there, we've learned that when using ipi combinations...ipi is the bad boy in terms of adverse effects.  That is why many of the ipi/nivo combo trials have 'flipped' their a smaller dose of ipi and a larger one of nivo...creating a much better side effect profile and as good or better results. What would the results of this study have been if ipi had been dosed at the now FDA approved 3mg/kg? 
  • As I've noted in several prior posts...there are many ongoing/developing studies looking at immunotherapy combinations:  ipi and nivo, ipi and TVEC, ipi and INCBO24360 (an IDO inhibitor)....not to mention...Pembro and TVEC, Pembro and an IDO inhibitor, Pembro and BRAFi, Nivo and antiCD137, Nivo and anti-LAG-3...etc.  I fear Sznol may be right.  While these results would have looked incredibly good to me when I needed treatment in 2010, thankfully, with the current anti-PD1 drugs and other immunotherapy combinations....ipi and Sargramostim may not work as well as some of the options currently available or rapidly on their way.
Hang in there, ratties.  It's a brave new world. - c
