Five Weeks at Eli Lilly: A Non-Traditional Experience

Posted by Unknown at Tuesday, January 24, 2017

With the majority of my clinical experiences under my belt, come October it was time to drive the four hours to Indianapolis to begin my rotation at one of the world’s largest pharmaceutical companies.

Lilly, like most large companies, specializes in a handful of therapeutic areas: oncology (gemcitabine, pemetrexed, cetuximab, among others), neuroscience (the largest Alzheimer's development program on Earth), diabetes (Humalog, Humalin), and bio-medicines. The Bio-medicines unit covers a handful of smaller focus areas, including men's health, cardiovascular, pain, and others. While they have a global presence, their headquarters in Indianapolis also houses most of their production facilities, which I will discuss more later. For more background on Lilly, here is their Wikipedia page.

I had no idea what to expect going in--my preceptor is a clinical research scientist in Early Phase Oncology Clinical Development. I would quickly discover what that means!

Day 1:

I stayed about 20 minutes from Lilly's technology campus (about a 10 minute drive from their headquarters) at a friend's house whose family generously offered to allow me to stay with them (great coincidence!). The day began with a few hours of onboarding (filling out paperwork, safety training, etc.) after which I drove to the main campus to meet my preceptor.

All of the buildings on the main campus are connected underground, including the parking garages! The campus is massive--with restaurants, dry cleaning, a bank, a gym, track, and soccer fields, and other amenities on-site. We spent most of the morning discussing my preceptor's role and where I would be fitting in. It breaks down like this:

My preceptor is a clinical research scientist. As a PharmD in this role, he is responsible for the day-to-day operations of his clinical trials. This could mean ensuring enrollment is on-track, monitoring incoming safety and efficacy data (blinded!), and importantly, answering clinical questions from the providers at the research sites regarding eligibility, enrollment, side-effects, clinical management, and anything and everything in between for any of the sites scattered around the world.

Outside of the Phase III trial he is responsible for, he is required to put on his early phase hat from time to time. This might mean working with the pre-clinical development group to identify promising leads or providing recommendations for unmet medical needs that could drive a new project, authoring study reports, protocol, or manuscripts, or designing trials. This is a role with an incredible diversity of responsibilities and work types--perfect for precepting a student!

Day 2 and Beyond:

Typical days worked like this: I could arrive anywhere between 6 and 9 AM, staying until 3 to 6 PM. I was issued a company laptop that allowed me to work from home provided I had no in-office responsibilities (though I always cleared these days with my preceptor). I opted to arrive early and leave early to avoid the minimal traffic that Indianapolis developed along my route.

The work environment is highly interdisciplinary and they use an open-office environment. With your laptop you can sit more-or-less wherever you would like, lock into a dock (with a large screen and peripherals) and work there all day or move around. Few people have permanent desks but there is tons of space to sit a group around a table, and space to work alone for a while if you need to as well. I was struck by walking down the halls and overhearing conversations by engineers, pharmacists, statisticians, physicians, PhDs of all flavors, and more!

My major projects could be summarized as follows:

Safety Monitoring or Other Reporting:

As I have a computer science background, I asked for data-centric projects where possible. I was routinely given blocks of data to crunch and provide recommendations. Usually, this was blinded adverse event data from a trial. With pivot tables and a little VBA these usually went quickly. Other reporting included analyzing concomitant medications and correlating those with outcomes, or doing demographic breakdowns for relevant groups. Notably, one project had me examine the different subtypes of cancers in these trials and examine the rates and locations of metastasis and correlate these with other relevant biomarkers--are there patterns? Are these in-line with literature, if it exists? Clinical trials are valuable sources of medical knowledge even outside the medication they are testing--we've learned a lot!

Medical Information and Writing

A major responsibility of the CRS is medical writing--whether that be trial manuscripts, clinical study reports (a data summary of a clinical trial), or communication with healthcare providers. I was tasked with authoring a manuscript for a Phase I dose-escalation trial that had not yet made it to publication. I had the opportunity to dig deep into a clinical study report, learn a disease-state inside and out, and work with the primary investigators (physicians and pharmacists) to report what they had found. When I left, the study was squarely in the hands of the medical writers who were polishing and editing the final draft!

As part of the CRS role, my preceptor received anywhere from 5-10 eligibility or clinical questions from the research sites worldwide. He passed many of them on to me, where I was responsible for evaluating their question, examining the protocol and literature where appropriate, providing a recommendation, and drafting a response.

Protocol Authorship

My final major project was built around a handful of pre-clinical compounds that Lilly had been working on for some time. They targeted a genetic mutation that is believed to drive the growth of several cancers. It was left to me to examine the literature and define where the greatest unmet medical need existed; meaning which cancers lack available treatments and have high rates of mortality (e.g. pancreatic cancer) versus a cancer that the mutation might be less common in, or the cancer has powerful existing therapies available. This was much more complicated that I initially expected, given that even identifying people with the mutation consistently was a problem. What assays should we use and how do they work? There were over a dozen methods that were not correlated with each other, and then attempting to work out how they correlated with outcomes was another hurdle.

This culminated in authoring a protocol synopsis: taking everything I had learned and transforming that into a study summary including information like: what cancers, who are we targeting, how do we identify them? What inclusion and exclusion criteria should be used to that effect? What are the treatments we'll use? What study design? What endpoints will be used and how are they measured? And much, much more!

Other

Lastly, Lilly has a structured program for visiting P4 students where you will meet dozens of practicing pharmacists from roles all over the company. There were usually 2 or 3 weekly, plus any other one-on-one meetings that you could schedule anywhere you'd like. One of the pharmacists works in the manufacturing facility, so we got a tour and saw how many of their drugs are made! Incredible to see!

I had a wonderful time at Lilly, and now there are even more opportunities to go! I hope this gives you a good idea of what I did while I was there--I definitely learned that this is where I want to end up!

Dipping my toe in the clinical pool

Posted by mariarx at Wednesday, July 18, 2012

So, my first rotation was health system administration with Dr. Brummond. I learned a TON during my 5 weeks with him - but very little of it was clinical. My interactions regarding medications maxed out at "which meds are on shortage and what do we switch to?"

For my 2nd rotation, I am at Providence Park Hospital in Novi, MI with the peds/oncology clinical pharmacist Missy. It's a pretty small hospital, around 200 beds, and has been open for 4 years now. Pharmacists at PPH take on an interesting role, with some duties falling into classic inpatient order verification; while others fall into antibiotic kinetics/anticoagulation monitoring. The great thing about it is all the pharmacists do everything. There is very little split between clinical/order verification roles.

My first week at PPH was spent mostly with technicians - messenger, IV room (where Frank threw me right in), packager, etc. I also got to spend some time with the OV pharmacists and checking orders that came through. I quickly learned to have lexicomp on stand by to look drugs up that I didn't recognize or know the dosing for.

Week 2 was half pharmacist shadowing and half reviewing kinetics. Oh boy, that was a doozy. Being handed a stack of practice cases and an equation sheet took me right back to P3 first semester therapeutics and Dr. Nagel's exam. Going through my practice problems was a test in frustration and insanity. No matter what I tried, I never seemed to get the right number, and man were my peaks and troughs all over the place. After making me suffer for a couple days, my pharmacist handed over the handheld PCs that have the nifty PK calculators on them. Although, I think I'll have to do some kinetics problems every once in a while so that I don't forget it completely. It's somewhat comforting to know that 'real pharmacists' use the same equations we got in class.

Week 3 was probably my favorite. In addition to starting 10 hour shifts (woo 3 day weekend!), I also started ICU rounding. At PPH, the OR/critical care and metabolic support pharmacists split ICU rounding duties. Each day of rounding started off with printing out a rounds summary report of all the ICU patients, and then going through their profiles and MAR compiling the big picture. The first day of rounding, it took me the full 3 hours to go through my patients. During this week I usually had lexicomp, micromedex, Dr. Carvers bug-drug list, wikipedia, google, and dosing nomograms on standby at all times. I was constantly looking things up and writing little notes down. Rounds each day varied from 1 hour to 2.5 hours depending on the intensivist, number of patients, and any unforeseen circumstances that arose. My second day, rounds started an hour late since the doctor was at a code (on a patient that soon joined us in the ICU). The 4 days of ICU rounding were great, and make me even more excited for my ED rotation in October.

This week has been all about antibiotic kinetics and anticoagulation monitoring. Pharmacists at PPH monitor drugs such as vancomycin, aminoglycosides, heparin, warfarin, rivaroxiban, and dabigatran. I got to work up initial doses for these drugs, and then do follow up monitoring for the rest of the week. This is where I really feel the pain of paper charts. PPH is half electronic and half paper. So, each day when we work up coumadin doses, or dose vancomycin or gent we have to then troll through the hospital to find our patient's charts. I haven't had too much trouble with it so far, but I can only imagine the frustration of a floating chart when all you want to do is add a quick note.

Next week (holy crap, I can't believe it's already week 4) I'll be working on TPNs with Maria, the metabolic support pharmacist, spending a day in the OR (I asked my preceptor Missy for blood and guts), and giving my final presentations. My projects for this rotation included making a formulary review document for Exparel, updating chemotherapy drug info sheets, and my journal club topic.

I have really loved my time at Providence Park. The smaller hospital setting might not have the super crazy cases, but for an institutional rotation I have gotten to do a lot of different things. This has definitely been great practice leading up to my generalist rotation which I have next at UM. I also really like the camaraderie among the staff... a lot of the techs, pharmacists, doctors, etc have been with St. John Providence for a long time before moving to the new site; and having such a small staff means you really know everyone. The only thing I won't miss about PPH is the drive - curse you one lane roads!

Institutionalized

Posted by Jim Stevenson at Wednesday, February 09, 2011

In January, I joined the pharmacists at St. Joseph Mercy in Howell for my institutional rotation. To my surprise, their central pharmacy was not in the basement, but in fact had a skylight – an unheard of addition to the usual pharmacy décor. But it was not just natural sunlight that I was exposed to on rotation – I also gained an understanding of pharmacists’ roles in a small (census ~70) community hospital.
The three pharmacists at St. Joe’s rotated through staffing and clinical roles. The clinical pharmacist attended rounds every morning and handled pharmacokinetic dosing, while the staff pharmacist verified orders, checked compounded medications, and answered drug information questions. As a student, I participated in functions from both roles.
Through this rotation, I gained experience making IVs, checking compounded medications, and checking cart fills. Additionally, I ensured that patients had proper DVT and stress ulcer prophylaxis, proper antimicrobial therapy, and renally adjusted doses. However, the most helpful aspect of this rotation was talking through complex pharmacokinetic dosing situations with the pharmacists. It is one thing to calculate a dose on a pharmacokinetics test in class, and another thing completely to dose a drug to a target steady-state concentration in a patient with fluctuating renal function.
