Tumor Lysis Syndrome – what is it and why is it important in cancer research?

After the hullabaloo on Friday regarding AbbVie’s suspension of the ABT-199 trials following not one, but two, unexpected deaths from tumor lysis syndrome (TLS), a few people asked what is this condition and what causes it?

In simple terms, lysis is a medical word used to describe the break up or breakdown of cells – whether through decomposition, destruction, or dissolving. Thus, we have hemolysis, which is the destruction of red blood cells with the release of hemoglobin.

Effectively targeting KRAS in lung cancer with a MEK inhibitor

Today is the 1000th blog post here on PSB, a milestone I never imagined actually reaching while writing the inaugural and rather boring post way back in 2006. At that time, 10 posts seemed a lot, never mind 100 or 1000! Anyway here we are, thus the facing the new dilemma of what to write about to celebrate the event.

Time to rethink cancer clinical trials strategy?

Recently, I’ve been pondering clinical trial design and wondering whether there is better way to do things, since much of the current concepts were based on cytotoxics that often had a very narrow therapeutic window.  With the advent of oral tyrosine kinase inhibitors (TKIs), the model seems, well, a bit old and tired and doesn’t always help us develop the optimum outcome.

In phase I oncology clinical trials, for example, we seek to find the MTD, as explained by Drs Rubenstein and Simon (PDF download) at the NCI:

ASCO 2012 Update 2: Overcoming resistance in metastatic melanoma

ASCO 2012 Posters 300x225 ASCO 2012 Update 2: Overcoming resistance in metastatic melanomaFollowing on from my preview of the 2012 American Society of Clinical Oncology (ASCO) meeting, I am now working through updates on some of the hot topics.

I’m delighted to announce The Chemical & Engineering News blog ‘The Haystack’, have published my second guest post on advances in metastatic melanoma.

This is a devastating disease that has seen very few advances over the last decade since the approval of dacarbazine (DTIC) until last year when the FDA approved two new therapies in vemurafenib (Zelboraf) for patients with the BRAFV600E mutation and ipilumumab (Yervoy), an immunotherapy that targets CTLA4.

Aggregating the 2012 ASCO tweets

It’s that time of the year – the annual American Society of Clinical Oncology (ASCO) conference in Chicago begins in earnest with Friday being the main travel day for many people before they hit the ground running for the poster sessions this afternoon.

This year, in addition to insights and analysis here on PSB, I’m delighted to announce that I’ll be writing some posts for the Chemical and Engineering News (C&EN) blog, The Haystack after the meeting (links to follow).

Stunning data with dabrafenib (BRAFV600E) in metastatic melanoma and brain metastases

Sometimes following the progress of cancer drugs can be very depressing given the failure rate, but every now and then something comes along that really brightens the landscape considerably. This week was one of those times.

Eighteen months ago, I posted a note from the 2010 ESMO meeting regarding GSK’s GSK208436 (now known as dabrafenib) in an early phase I/II trial in brain metastases associated with melanoma that was presented by Dr Georgina Long on behalf of an Australian group.

Do check out that original post – it’s well worth reading for some background context in the light of the new data.

ASCO 2012 Preview – Highlights of key data emerging from Chicago

It’s that time of the year again where we cogitate and contemplate on what might be hot at the annual meeting of the American Society of Clinical Oncology (ASCO) before the abstracts are available (they’re released online tomorrow at 6pm ET).

This year, while interesting early data from up and coming small biotechs is likely to be eagerly presented in poster sessions, the focus is more likely going to be on big Pharma with various phase III and also late phase II trials that are due to report data.  Unfortunately, not all of these will produce overwhelmingly positive results though!

ASCO 2012 Acronym Mania!

Many of you will remember PSB reader Dr Al Lalani of Regeneron’s guest blog post around this time last year with a quick summary of the key clinical trials at the American Society of Clinical Oncology (ASCO) meeting based on the study acronyms, which turned out to be highly popular.

Fortunately, Al has kindly sent in a review of this year’s trials in a very creative fashion, as you can see below (PSB: Thanks, Al!).

Ribonucleases (RNase) – clinical applications for cancer therapy

This is the second post of a two-part mini series on RNases with Dr Laura Strong of Quintessence Biosciences.  If you haven’t yet read it, check out yesterday’s post, which focused on Ribonucleases (RNase) – what are they and why are they relevant to cancer?

Yesterday, we learned that RNases kill cancer cells by a novel mechanism – destruction of RNA – and may be synergistic with some chemotherapy agents.

Ribonucleases (RNase) what are they and why are they relevant to cancer?

At the recent American Association for Cancer Research (AACR) meeting, I had the pleasure of meeting several interesting young scientists and physicians either in the poster halls or in various scientific sessions.  It seemed a great idea to encourage some of them to contribute some guess blog posts here on PSB.
