Sew Chaotically! ~ On the Kalle band wagon...


I've liked so many versions of the Kalle Shirt and Shirt dress by Closet Case Patterns floating around on sewing blogs and IG that I finally made my own!  It's a straight size 10 with the back lengthened by 1 inch and the front by 2 inches, side seams blended to match, and finished with bias binding.

I rounded the collar inspired by and using Lauren's tips from her blog at Guthrie and Ghani
As is true with most patterns, the appearance of the Kalle is much influenced by the material used.  I knew this stiffer cotton would lend the garment a boxy shape, which was the goal for this one.  However, I plan to make up another in a more fluid crepe for a completely different look!
I like it with my newly altered white jeans for now...but it should layer nicely in cooler weather!


Definitely fun to make and wear!  Happy Tuesday, Y'all!!! - les

Antibiotics, gut microbiome and heavier is better in relation to melanoma?????


I've been writing about the cooties in our guts - our microbiome - since 2015.  This post from 2018 includes lots of links to prior articles and reports:  Microbes again...and how they may be associated with improved response to anti-PD-1 for melanoma patients...and you might even laugh!!!

In June of this year, out of ASCO, the mircobiome was also addressed. I included a report on a couple of their articles here:  The first installment of this year's ASCO review.  That post included:

#6:  The "microbiome" craze is not exactly 'new' as it has taken over the universe! BUT!!!  How much is hype?  How much is real?  How can we drill down on the details?  How can we harness what we know to impact treatments such that patients benefit?  The next 3 posts address this topic.  Now, there's this:

A phase I/II study of live biotherapeutic MRx0518 in combination with pembrolizumab in patients who have progressed on prior anti-PD-1 therapy.  2019 ASCO.  Shubham, Imke, Amishi, et al. J Clin Oncol 37, 2019 (suppl; abstr TPS2670) 

Background: The gut microbiome has emerged as a new therapeutic target to augment the efficacy of immune checkpoint blockade. MRx0518 is a novel, gut microbiome-derived, oral live biotherapeutic, designed to induce a broad immunostimulatory response to re-engage PD-1 inhibitor activity. Preclinical studies showed that MRx0518 reduced tumour growth in models of kidney, lung and breast cancer. MRx0518 increased CD4 and CD8 T cell and NK cell infiltration into the tumour and decreased Tregs. Upregulation of tumour TLR5 was observed and linked to the bacterial flagellin moiety, which was shown to strongly induce NFκB, cytokine responses and IFNγ+ CD4 and CD8 T cells. The study, one of the first oncology trials conducted with live biotherapeutics, is a single center, open label, safety and preliminary efficacy study of MRx0518 in combination with pembrolizumab in patients with solid tumors who have progressed on PD-1 inhibitors. Methods: Trial consists of 2 parts. In Part A, 12 patients receive pembrolizumab 200 mg every 3 weeks plus 1 capsule (bid) of MRx0518 with a DLT period of 1 cycle (21 days). In Part B, up to 30 patients per cohort (NSCLC, Urothelial, Renal and Melanoma) will receive pembrolizumab 200 mg every 3 weeks plus 1 capsule (bid) of MRx0518 for up to 35 cycles or until disease progression per RECIST 1.1. The primary end points are safety and tolerability of MRx0518 in combination with pembrolizumab (Parts A and B) and clinical benefit of MRx0518 in combination with pembrolizumab (Part B). Secondary end points are objective response rate, duration of response, disease control rate, and progression-free survival. Exploratory end points include biomarkers of treatment effect, effect on microbiota and overall survival. Recruitment is ongoing. Clinical trial information: NCT03637803

Here, researchers are going to give the first 12 patients with solid tumors who have progressed on anti-PD-1, Pembro every 3 weeks along with a capsule of MRx0518, a "live biotherapeutic", taken by mouth, twice a day for one 21 day cycle.  In part b, the plan is that 30 patients could be given the same for up to 35 cycles or until disease progression.  My only concern here would be the fact that we've found that folks who took probiotics from a bottle did not do so well, while those that got their cooties from foods like Kefir, kimchi, yogurt, sauerkraut, etc. - did better.  If I were to consider participation in this study, I'd be asking my doc about that.

#7:  As I noted above, these last two reports are more along the lines of ~ "What once was old is new again!" I've been talking about the Cooties in our Gut since 2015, putting it all together in this post from 2018:  Microbes again...and how they may be associated with improved response to anti-PD-1 for melanoma patients...and you might even laugh!!!  Still, there is much we don't understand about how all this works.  Now, there's this:

Gut microbiota dependent anti-tumor immunity restricts melanoma growth in Rnf5-/- mice.  Li, Tinoco, Elmen, et al.  Nat Commun. 2019 Apr 2.

Accumulating evidence points to an important role for the gut microbiome in anti-tumor immunity. Here, we show that altered intestinal microbiota contributes to anti-tumor immunity, limiting tumor expansion. Mice lacking the ubiquitin ligase RNF5 exhibit attenuated activation of the unfolded protein response (UPR) components, which coincides with increased expression of inflammasome components, recruitment and activation of dendritic cells and reduced expression of antimicrobial peptides in intestinal epithelial cells. Reduced UPR expression is also seen in murine and human melanoma tumor specimens that responded to immune checkpoint therapy. Co-housing of Rnf5-/- and WT mice abolishes the anti-tumor immunity and tumor inhibition phenotype, whereas transfer of 11 bacterial strains, including B. rodentium, enriched in Rnf5-/- mice, establishes anti-tumor immunity and restricts melanoma growth in germ-free WT mice. Altered UPR signaling, exemplified in Rnf5-/- mice, coincides with altered gut microbiota composition and anti-tumor immunity to control melanoma growth.

So, a lot of fancy words to say that mice with a certain microbiome component (less UPR expression) responded better to immunotherapy.  Further, when those mice lived with mice whose gut initially did not possess those properties, researchers found that they too developed an altered gut flora and a greater ability to restrict the growth of melanoma.  Bottom line:  Live with somebody who has the right cooties!  (If you can figure out who exactly that is!!!)

#8:  Given the fact that a certain "microbiome" aids our responses to immunotherapy while a different one does not, it makes sense that antibiotics, which kill off bacteria that are trying to do us harm as well as those who may do a body good, could be problematic when trying to foster cooties that improve our response to immunotherapy.  Here are some earlier articles and explanations:

This from 2017:  Antibiotic use MAY decrease effectiveness of immunotherapy?????

And this from April of this year:  DECREASED progression free survival in melanoma patients treated with antibiotics prior to or at start of immunotherapy!!!!  In that study it was noted that, despite - "Small numbers. ..the 10 folks, from the 74 advanced melanoma peeps examined, who were given antibiotics within 30 days of their immunotherapy, had more resistance to treatment, a shorter length of progression free survival (2.4 vs 7.3 months) and overall survival was shorter at 10.7 months vs 18.3 months." 

Now, there's this:

Effect of antibiotic exposure in patients with metastatic melanoma treated with PD-1 inhibitor or CTLA-4 inhibitor or a combination of both.  2019 ASCO. Kapoor, Runnels, Boyce, et al.  J Clin Oncol 37, 2019 (suppl; abstr e14141)

Background: Pre clinical studies have demonstrated the effect of gut microbiome in the efficacy of immune check point inhibitors. The effect of antibiotic exposure to patients receiving PD-1/CTLA-4 inhibitor therapy has not been extensively studied, especially in metastatic melanoma. In this study, we demonstrate the effect of antibiotic exposure to metastatic melanoma patients receiving PD-1/CTLA-4 inhibitor therapy. Methods: We performed aretrospective analysis of 108 patients with stage 4 metastatic melanoma who received immunotherapy with PD-1 inhibitors or CTLA-4 inhibitors or combination of both between Nov 2010 and Oct 2017. Patients were divided into Abx(+) and Abx(-) groups that were defined as patients exposed or not exposed to antibiotics respectively. The time frame for antibiotic exposure was taken from 6 months prior to 1 month after initiation of immunotherapy. We compared progression free survival (PFS), overall survival (OS) and response rate (RR) between the two groups. RR was calculated based on the entire length of follow-up.  Results: Out of 108 patients, 66 were men, with a mean age 64.6 ± 15.1 years. 46 patients were exposed to antibiotics of varied classes. Median PFS in abx(+) group [88 days] was shorter as compared to abx(-) group [322 days].Patients in abx(-) group had a 68% reduced risk of progression within 200 days of immunotherapy initiation adjusting for sex, age and number of immunotherapy cycles . Median OS in ab(+) group [294 days] was shorter as compared to abx(-) group [573 days]. Response rate defined as percentage of patients whose cancer was stable or entered remission was 12.9% in abx(-) group as compared to 8.7% ab(+) group. Patients in abx(-) group had a 52% reduced risk of death adjusting for sex, age and number of immunotherapy cycles. Conclusions: Antibiotic exposure is associated with poorer outcomes in patients with advanced metastatic melanoma being treated with PD-1/CTLA-4 inhibitors which is likely related to alteration of gut microbiome. Antibiotics should be prescribed with caution in patients undergoing treatment with immune check point inhibitors. These data should be validated in a larger patient population.

In this retrospective study of 108 melanoma patients treated with immunotherapy, it was noted that 46 were given antibiotics at some point between 6 months prior and 1 month after starting their immunotherapy treatment.  PFS was 88 days in those who took antibiotics and 322 days in the group who didn't.  OS was 294 days in the antibiotic group - 573 days in the non-antibiotic group.  Response rate was 8.7% in the group that had taken antibiotics vs 12.9% in the group that had not been exposed to antibiotics.  As I wrote in the post I put up in April:  "So...if you really NEED antibiotics, they may save your life and will certainly decrease misery. BUT, if you DON'T really NEED them...they can cause harm, in lots of ways."

Now, there's this:

Cumulative Antibiotic Use Significantly Decreases Efficacy of Checkpoint Inhibitors in Patients with Advanced Cancer.  Tinsley, Zhou, Tan, et al.  Oncologist. 2019 Jul 10. 

With the advent of immunotherapy, substantial progress has been made in improving outcomes for patients with advanced cancer. However, not all patients benefit equally from treatment, and confounding immune-related issues may have an impact. Several studies suggest that antibiotic use (which alters the gut microbiome) may result in poorer outcomes for patients treated with immune checkpoint inhibitors (ICI).

This is a large, single-site retrospective review of n = 291 patients with advanced cancer treated with ICI (n = 179 melanoma, n = 64 non-small cell lung cancer, and n = 48 renal cell carcinoma). Antibiotic use (both single and multiple courses/prolonged use) during the periods 2 weeks before and 6 weeks after ICI treatment was investigated.

Within this cohort, 92 patients (32%) received antibiotics. Patients who did not require antibiotics had the longest median progression-free survival (PFS), of 6.3 months, and longest median overall survival (OS), of 21.7 months. With other clinically relevant factors controlled, patients who received a single course of antibiotics had a shorter median OS (median OS, 17.7 months), and patients who received multiple courses or prolonged antibiotic treatment had the worst outcomes overall (median OS, 6.3 months). Progression-free survival times were similarly affected.

This large, multivariate analysis demonstrated that antibiotic use is an independent negative predictor of PFS and OS in patients with advanced cancer treated with ICIs. This study highlighted worse treatment outcomes from patients with cumulative (multiple or prolonged courses) antibiotic use, which warrants further investigation and may subsequently inform clinical practice guidelines advocating careful use of antibiotics.

Antibiotic use is negatively associated with treatment outcomes of immune checkpoint inhibitors (ICI) in advanced cancer. Cumulative antibiotic use is associated with a marked negative survival outcome. Judicious antibiotic prescribing is warranted in patients receiving treatment with ICI for treatment of advanced malignancy.

Granted none of the patients in this study had melanoma.  And, as I noted above, if you need antibiotics, they can be essential and life saving.  But - if they are not required - they may cause us more harm than good.

And, finally - this:

Modifiable Host Factors in Melanoma: Emerging Evidence for Obesity, Diet, Exercise, and the Microbiome.  Warner and McQuade. Curr Oncol Rep. 2019 Jul 1.

We discuss how potentially modifiable factors including obesity, the microbiome, diet, and exercise may impact melanoma development, progression, and therapeutic response.  Obesity is unexpectedly associated with improved outcomes with immune and targeted therapy in melanoma, with early mechanistic data suggesting leptin as one mediator. The gut microbiome is both a biomarker of response to immunotherapy and a potential target. As diet is a major determinant of the gut microbiome, ongoing studies are examining the interaction between diet, the gut microbiome, and immunity. Data are emerging for a potential role of exercise in reducing hypoxia and enhancing anti-tumor immunity, though this has not yet been well-studied in the context of contemporary therapies. Recent data suggests energy balance may play a role in the outcomes of metastatic melanoma. Further studies are needed to demonstrate mechanism and causality as well as the feasibility of targeting these factors.

Sew Chaotically! ~ Metamorphic dress, sun flowers, love and ~ HAPPY BIRTHDAY, Ruthie!


After the successful Metamorphic top, I embarked on the dress!  It's made up in two luscious fabrics:  Telio Viscose Denim in dark blue and Hudson Bay Hand Dyed Rayon Challis in Blue, both from Fabric.com  I cut the size corresponding to my bust measurement (size 10), utilized a one inch side seam on the bodice, and while I shortened the top by 3 inches, here I added 9 inches in length.  Because of the 'flimpiness' of both my fabrics, the dress is fabulously light weight and hangs nicely, though hemming was a bit of a nightmare in trying to keep things even and falling as they should.  In fact, after these pics were taken, I bit the bullet, whacked the muggled-up hem OFF, and completed a baby hem on both which made me much happier!!!  Not sure about the meaning of "FLIMPY"?  This post tells the tale:  Sew Chaotically! - Cute little summer dress ~ McCall's 7242


I love BOTH sides of this dress.  The waterfall color way is incredibly pretty, but I really like having the contrast effect on the "solid" side as well.  Plus, though not completely evident in these pics, the solid fabric has an especially lovely hand and a bit of a sheen to it.  I was super excited to get to wear it on a girls get-a-way with Roo down to Ruthie's!!!  And when Ruthie tells you she has a "special thing we are gonna do!  It's a surprise!" ~ She's for realz!!!!

How cute!!!  What????
Is this not SPECIAL??????
Keep'n it shady!  Yep, that's my Metamorphic dress (Sew Liberated) and check out Ruthie's Celestial dress (Pattern Fantastique) in a fab African Wax Print B picked for her!

Beautiful Roo, unfazed by the insane antics of her auntie and mum!




Thanks so much for a lovely visit, Ruthie!  Thanks for sharing it with me, Roo!  I don't know how I would manage without you two!!!  I am so lucky!!!  Much love to you both.  Happy, happy day Ruthie!!!!! ~ Cess

Neoadjuvant ipi/nivo as well as Neoadjuvant BRAF targeted therapy for unresectable melanoma lesions


Could neoadjuvant treatment (melanoma treatment administered BEFORE a lesion is surgically removed or radiated) be the way of future melanoma treatment???  Here's the data so far: Neoadjuvant reports related to melanoma

Now, there's this~

Successful Treatment of Unresectable Advanced Melanoma by Administration of Nivolumab With Ipilimumab Before Primary Tumor Resection.  Fujimura, Kambayashi, Sato, et al.  Front Med (Lausanne). 2019 Jun 26.

Ipilimumab, in combination with nivolumab, is one of the promising drugs that enhance the anti-tumor immune response of patients with advanced melanoma. Since the co-administration of nivolumab with ipilimumab in the neoadjuvant setting expands melanoma-reactive T cells at the primary site of melanoma and has a high rate of histological complete response, the pre-surgical administration of this combination could be the optimal therapy for unresectable advanced melanoma. In this report, a case of unresectable advanced melanoma treated successfully with administration of nivolumab with ipilimumab before primary tumor resection is presented. In addition, CD8+ T cells increased among the tumor-infiltrating lymphocytes that were surrounding melanoma cells and caspase 3+ cells. The present case suggests that pre-surgical administration of nivolumab with ipilimumab could be the optimal therapy for the treatment of unresectable advanced melanoma.

Neoadjuvant BRAF-targeted therapy in regionally advanced and oligometastatic melanoma.  Eroglu, Eatrides, Naqvi, et al. Pigment Cell Melanoma Res. 2019 Jul 22. 

Current management of locoregional and oligometastatic melanoma is typically with surgery; however, some patients are unable to undergo resection due to location/size of their tumors and/or the anticipated morbidity of the surgery. While there are currently no established guidelines for neoadjuvant therapy in melanoma, neoadjuvant BRAF-targeted therapy may make resection more feasible.

A retrospective analysis was conducted of 23 patients with BRAFV600-mutant, stage III/IV melanoma treated with BRAF-targeted therapy prior to surgery, with no adjuvant treatment. Surgical specimens, preoperative imaging and clinical outcomes were evaluated.

Ten of 23 patients (44%) attained a pathologic complete response (pCR), with no correlation between RECIST-response based on preoperative imaging and pathologic response. After a median of 43 months follow-up, only 1 patient (10%) with a pCR recurred; while 8 of 13 (62%) patients without a pCR recurred. Patients with a pCR had significantly improved relapse-free (RFS) and overall survival (OS) compared to patients with residual tumor.

Neoadjuvant BRAF-targeted therapy is associated with a high pCR rate in patients with stage III-IV melanoma, which may correlate with improved RFS and OS. 

Overall, still early days, but neoadjuvant treatment may be very good news for many melanoma patients, especially those for whom surgery is not an option.  Hang tough ratties!!  ~ c

Sew Chaotically! ~ #alteritaugust or #refashion - you choose!!!


I've been making and remaking garments for awhile. Some outcomes were more successful than others.  Here are a few highlights:

Roo's old running tees worked into a "quilt":  T-shirt quilt with Roo

Work tees also transformed into a quilt as well as exercise tops:  Refashion! (It covers a lot!)

Reworking a sweater, a project that provided lots of laughs with SAD results:  It's Sooooo bad!!!

Dresses to skirts are easy refashions!  One is a bit buried in this post:  Toaster sweater, refashion and plans!  There's this one:  Me mades - refashioned  And here, Roo's frumpy dress became a skirt AND a top, while my old knit skirt was transformed into a cute and comfy Niko top:  REFASHION!!! Skirt to Nikko and dress to useful separates

The Polly top, a fab FREE pattern from By Hand London, is a great way to use scraps or pieces from existing clothes that need an upgrade!  This post covers two!  Fabric from an old sweater comprised the center front piece on the pink one and an unused scarf found a beautiful new life as the back and contrast front piece in the version I made for Roo:  Another By Hand London, Polly Top

Sewing allows all of us to create new garments just as we wish them to be, transform old bits and bobs into something fresh, or adjust the fit of existing garments.  Sew!  Newly inspired by Mia, of Sew North's #alteritaugust sewing challenge, I FINALLY got around to adjusting a pair of rtw white jeans to fit my bootie.  Despite my slender build, I have chronically had problems with the waist band on many rtw pants standing up in the back rather than cinching in and laying flat as it should - often placing a couple darts in the band until I started making my own!!!  Not a very eloquent solution, but it was fast and did the job.  One reason I'd put off adjusting these particular pants was the fact that darts were not enough to solve the problem!!!
As you can see from this older pic, the front is terribly baggy too!!!
Forgive the plethora of bootie pics coming your way - butt... (Ha ha ha!!  I crack myself up!!!)

Pretty good, no?  To create this fix, I took off the center back belt loop and the waist band from the back of the pant for about 4-6 inches to either side of the center back seam.  Took the center back seam apart all the way down to the crotch. Fitted and stitched the seam back together.  Serged and trimmed away the excess and top stitched the seam back down.  Took a chunk out of the waist band, restitched it together, such that that seam would be hidden beneath the belt loop when it was reattached, then re-fixed the loop and waist band to the pant!  Literally a pain in the pa-toot to do, but well worth it now that I have a more wearable pair of pants!!
Look!!  The waist band actually FITS my waist!!!
And the front is now the "flat front" it should have been all along!
Thanks, Mia!  Your challenge was just the kick in the pants I needed!!!  #alteritaugust and sew chaotically! ~ les

Treating melanoma by COMBINING targeted therapy AND immunotherapy!!


As usual, I've written on this topic previously:

As long ago as 2015, there was this:  BRAFi better when combined with or after immunotherapy and surgery!!!

And this in 2016:  BRAF/MEK combined with immunotherapy!!!

This from 2017:  The whole she-bang - immunotherapy WITH BRAF/MEK for melanoma...

This from ASCO 2017:  ASCO 2017: Atezo (anti-PDL1) with Cobimetinib (MEKi) and Vemurafenib (BRAFi) for BRAF V-600 melanoma

Now there are these reports (highlights = my own):


Combined BRAF and MEK inhibition with PD-1 blockade immunotherapy in BRAF-mutant melanoma.  Ribas, Lawrence, Atkinson, Agarwal, ..., Hodi, ..., Hamid.  Nat Med. 2019 Jun;25.

Oncogene-targeted therapy with B-Raf proto-oncogene (BRAF) and mitogen-activated protein kinase kinase (MEK) inhibitors induces a high initial response rate in patients with BRAFV600-mutated melanoma, with a median duration of response of approximately 1 year. Immunotherapy with antibodies to programmed death 1 (PD-1) produces lower response rates but with long response duration. Preclinical models suggest that combining BRAF and MEK inhibitors with PD-1 blockade therapy improves antitumor activity, which may provide additional treatment options for patients unlikely to have long-lasting responses to either mode of therapy alone. We enrolled 15 patients with BRAFV600-mutated metastatic melanoma in a first-in-human clinical trial of dabrafenib, trametinib and pembrolizumabNCT02130466 ). Eleven patients (73%) experienced grade 3/4 treatment-related adverse events, the most common being elevation of liver function tests and pyrexia, most of which resolved with drug interruption or discontinuation of either the anti-PD-1 antibody or the targeted therapy combination. Eleven patients (73%) had an objective response, and six (40%) continued with a response at a median follow-up of 27 months (range = 10.3-38.4+ months) for all patients. This study suggests that this triple-combined therapy may benefit a subset of patients with BRAFV600-mutated metastatic melanoma by increasing the frequency of long-lasting antitumor responses.

Atezolizumab plus cobimetinib and vemurafenib in BRAF-mutated melanoma patients.  Sullivan, Hamid, Gonzalez, et al.  Nat Med. 2019 Jun;25.


Melanoma treatment has progressed in the past decade with the development and approval of immune checkpoint inhibitors targeting programmed death 1 (PD-1) or its ligand (PD-L1) and cytotoxic T lymphocyte-associated antigen 4, as well as small molecule inhibitors of BRAF and/or MEK for the subgroup of patients with BRAFV600 mutations. BRAF/MEK-targeted therapies have effects on the tumor microenvironment that support their combination with PD-1/PD-L1 inhibitors. This phase Ib study (ClinicalTrials.gov, number NCT01656642 ) evaluated the safety and anti-tumor activity of combining atezolizumab (anti-PD-L1) with vemurafenib (BRAF inhibitor), or cobimetinib (MEK inhibitor) + vemurafenib, in patients with BRAFV600-mutated metastatic melanoma. Triple combination therapy with atezolizumab + cobimetinib + vemurafenib, after a 28-d run-in period with cobimetinib + vemurafenib, had substantial but manageable toxicity. Exploratory biomarker data show that the cobimetinib + vemurafenib run-in was associated with an increase in proliferating CD4+ T-helper cells but not with an increase in T-regulatory cells, as observed in the vemurafenib-only run-in period. The confirmed objective response rate was 71.8%. The estimated median duration of response was 17.4 months with ongoing response in 39.3% of patients after 29.9 months of follow-up. Further investigation in a phase III trial is underway.

Phase Ib study of atezolizumab combined with cobimetinib in patients with solid tumors.  Hellmann, Kim, Lee, et al.  Ann Oncol. 2019 Mar 27.

Preclinical evidence suggests that MEK inhibition promotes accumulation and survival of intratumoral tumor-specific T cells and can synergize with immune checkpoint inhibition. We investigated the safety and clinical activity of combining a MEK inhibitor, cobimetinib, and a PD-L1 inhibitor, atezolizumab, in patients with solid tumors.

This phase I/Ib study treated PD-L1/PD-1-naive patients with solid tumors in a dose-escalation stage and then in multiple, indication-specific dose-expansion cohorts. In most patients, cobimetinib was dosed once daily orally for 21 days on, 7 days off. Atezolizumab was dosed at 800 mg intravenously every 2 weeks. The primary objectives were safety and tolerability. Secondary endpoints included ORR, PFS and OS.

Between 27 December 2013 and 9 May 2016, 152 patients were enrolled. As of 4 September 2017, 150 patients received greater than/= to 1 dose of atezolizumab, including 14 in the dose-escalation cohorts and 136 in the dose-expansion cohorts. Patients had mCRC (n = 84), melanoma (n = 22), NSCLC (n = 28), and other solid tumors (n = 16). The most common all-grade treatment-related adverse events (AEs) were diarrhea (67%), rash (48%) and fatigue (40%), similar to those with single-agent cobimetinib and atezolizumab. One (1%) treatment-related grade 5 AE occurred (sepsis). Forty-five (30%) and 23 patients (15%) had AEs that led to discontinuation of cobimetinib and atezolizumab, respectively. Confirmed responses were observed in 7 of 84 patients (8%) with mCRC (6 responders were microsatellite low/stable, 1 was microsatellite instable), 9 of 22 patients (41%) with melanoma, and 5 of 28 patients (18%) with NSCLC. Clinical activity was independent of KRAS/BRAF status across diseases.

Atezolizumab plus cobimetinib had manageable safety and clinical activity irrespective of KRAS/BRAF status. Although potential synergistic activity was seen in mCRC, this was not confirmed in a subsequent phase III study.

So - small numbers.  Pretty significant toxicity.  Only effective in the roughly 1/2 of melanoma patients who are BRAF positive.  Looks like BRAF/MEK with anti-PD-1/PD-L1 is demonstrating a 70% objective response rate while anti-PD-L1 with a MEK inhibitor alone attained a 40% response rate (ie = no better than the ipi/nivo combo).  Again, no matter the result...small numbers treated (only 37 melanoma patients total were in the first and last studies reported here - and Hamid et al ain't sharing their #'s unless you buy the paper - FYI).  Still, throwing the "kitchen sink" at melanoma may be a worthwhile treatment for some.

Hang tough ratties!!! - c

Sew Chaotically! ~ Metamorphic Dress by Sew Liberated as a top!


Once I finally decided to bite the bullet and pick up Sew Liberated's Metamorphic Dress, an ingenious reversible pattern, after admiring it for over a year, I went all in and got the most fabulous fabric for my dream dress!  Since, my LOVE of the fabric gave me pause, I decided to test the pattern as a top before cutting into it.  I had just enough yardage to make a shortened version of the "top" layer of the dress from the last bit of shirting in the 3 yard pack I purchased from Fab Scrap.  I figured the somewhat staid plaid would be neat juxtaposed against the hippy dippy vibe of this top!!!

I think it worked!!!  As I am very behind in posting some of my makes and have already made the dress version, I can tell you that making this up in a slightly stiffer fabric emphasizes the peplum appearance of the design, while a drappier fabric does not.  Additionally, when you add length and weight of the additional fabric required for a full length dress plus factor in the two layers for the dress your fabric will behave accordingly.  Nothing surprising about that really, but didn't want to mislead sewing peeps about how the dress vs this top from the same pattern will hang!


So happy with how this top turned out!!
It is quite twirlable!!!


Who says twirling stops at 55????

Having used my last cut in this make, I remain very happy with my Fab Scrap fabric purchases!  In addition to the yardage utilized in this top, you can see how I stitched up two other cuts here and another here!
Keep twirling and sew chaotically!!! ~ les
