Navigating The FDA Advisory Committee Road To Success … Or Not

On the eve of FDA’s Antiviral Drugs Advisory Committee reviews of the first protease inhibitors for hepatitis C, the drugs’ sponsors – Merck (boceprevir) and Vertex Pharmaceuticals (telaprevir) – are no doubt scrambling to make sure everything is in order.

Presumably, the companies have already locked down their slide decks, put the finishing touches on their presentations, researched the backgrounds of the committee’s standing members and shipped their AdComm teams off to hotels near FDA’s White Oak headquarters, where the meetings will take place.

Boceprevir and telaprevir are viewed as therapeutic breakthroughs in the treatment of HCV, both having shown improved cure rates when added to the current standard of care. However, the drugs have complicated and differing dosing regimens, which are likely to be an area of AdComm discussion.

Merck, which will present its case on April 27, is an old hand at the AdComm process, having most recently gone before a panel in December when it unsuccessfully sought to add prostate cancer risk reduction language to the label of its BPH drug Proscar. Vertex, on the other hand, is making its maiden voyage on the USS AdComm. The company will present its case on April 28 and should benefit from hearing panelists’ questions and concerns in their review of boceprevir the day before.

No matter how well prepared the sponsors think they might be, the AdComm road is littered with landmines. That, in a nutshell, was the message conveyed by AdComm meeting veterans at the Center for Business Intelligence’s Second Annual Forum on Effective Preparation for FDA Advisory Committees in Washington, D.C. last month.

At the two-day conference, battle-hardened veterans of the AdComm process – including pharma employees and consultants who make their living preparing drug companies for meetings – shared experiences from the trenches and offered some best practices to consider when tackling what has become a significant hurdle in drug development.

Some suggestions fall in the common sense category. It's imperative not only to have good communications with FDA leading up to an AdComm, but also to begin the meeting planning process early. Practicing presentations and Q&A is not surprisingly also considered good AdComm hygiene. But the CBI speakers voiced some additional pearls of wisdom that sponsors appearing before FDA committees might want to keep in mind, starting with…

Know Your AdComm
Pete Taft, founder and CEO of PharmApprove, a company that provides AdComm meeting preparation services, said sponsors should be ready to deal with four general types of personalities on FDA panels:

the expert – someone who knows a lot about your field and possibly your product, and is going to be well prepared for the meeting;

the judge – an individual who is swift to make judgments about your product or argument;

the thoughtful one – a quiet panel member; and,

the naysayer – the “Simon Cowell of AdComs” who you can either fight or forget about securing their vote.

PharmApprove has interviewed former AdComm members to find out how they prepare and what they expect from sponsors. At the top of their list is this nugget of wisdom...

Keep It Simple, And Don’t Be Irritating
The importance of clarity and simplicity in a sponsor’s presentation was echoed by FDA Director of Advisory Committee Oversight Michael Ortwerth, the lone agency presenter at the CBI conference. “That’s a really important thing, that the message is clear … and slides are very well put together,” Ortwerth said. “When you have slides that are so busy and so ladened and heavy, then you can’t focus on what the actual issue is.”

If AdComm members don’t like busy slides, they’re also not thrilled with sponsors or presenters who come off as cocky or overconfident. “I’ve always had this intuitive sense that if we press the committee or cause them to feel irritated, that some of that emotion will be transferred to their rational thinking,” said Taft, whose suspicion has now been confirmed. He noted the comments of a former AdComm chairman, who said: “You don’t want to make me angry about you, because then I transfer that from you onto the data and onto the drug.”

AdComm prep needs to be heavy on practice, planning and contingency planning, the speakers said. In the course of advance planning, it’s important that sponsors …

Don’t Let Belly Dancers Get In The Way
Don Cilla, vice president and product development team lead at AstraZeneca’s MedImmune division, led the company’s AdComm team for the June 2010 review of motavizumab for prophylaxis of respiratory syncytial virus. He recommends conducting AdComm team practice sessions and holding pre-meeting preparations in the same hotel ballroom that FDA will use for the meeting (when they’re not being held at White Oak). At the time of the motavizumab meeting “there was a convention of belly dancers that had that room booked for the three days leading up to it, so we couldn’t get in there to practice.”

If the company's AdComm team is all staying, and eating, together as a group for two or three days before a meeting, they should …

Avoid Eating The Mayonnaise
One of the speakers at the CBI conference recounted how a consultant, upon seeing open mayonnaise sitting at a buffet, banned all condiments at future meals so as to avoid the risk that team members would come down with a debilitating case of food poisoning on the day of the big meeting. “We had backups for everybody,” Cilla said of his team for the motavizumab meeting. “We didn’t know if they were going to get the bad mayonnaise or the Mexican food the night before or if they just couldn’t get there.”

While sponsors should plan for anything and everything to go wrong logistically, there are some factors they may have no control over. This includes the possibility that committee members will be suffering from …

An Avandia Hangover
Back-to-back scrutiny of different drugs on consecutive days can have a detrimental effect on those coming at the end of a multi-day meeting, suggested Alexander Fleming, president and CEO of the consulting firm Kinexum.

Case in point is Vivus’ obesity drug Qnexa. At a July 15 meeting, FDA's Endocrinologic and Metabolic Drugs Advisory Committee voted 10-6 against approval due to safety concerns. The negative vote took some FDA officials by surprise, but Fleming believes timing was a crucial factor. The Qnexa review marked the third consecutive day of work for the committee, its two previous days having been spent on an extensive and intensive review of the cardiovascular safety of GlaxoSmithKline’s diabetes drug Avandia.

“If nothing else, the advisors had to be exhausted” by the time they got to Qnexa, Fleming said. Calling the AdComm timing “pure bad luck” for Vivus, Fleming said the company knew “this was going to be a real disadvantage to them ... and only in retrospect do you see how it really had a major effect.”

Sponsors also may have no control over an AdComm’s walk down the path of …

Comparative Effectiveness And Cost
Disease background presentations by the sponsor are a hallmark of any product-specific AdComm. A good presentation will include a comparison of products that are on the market, including mechanism of action and limitations, said Mary Rofael, COO of scientific and regulatory communications at ProEd Communications, a firm that provides AdCom prep services.

“Many of you will say we’re here at an advisory committee, the committee should focus on evaluating the benefit/risk of a particular product,” Rofael said. “In this day and age you can’t stop people from thinking about comparing it to what they’re using currently or what’s on the market. It’s just a discussion that’s going to take place. Whether or not you engage in it, that’s a different story, but it’s important to anticipate it because these kinds of questions are being asked more and more today.

“It’s almost like the question of cost,” Rofael continued, venturing down a road that almost no sponsor wants to travel during an AdComm. “The advisory committee room is the only room where cost is not discussed … but eventually I think it’s going to make its way in. People are starting to ask about the cost of products and what the burden of cost is on the health care system.”

Aside from the detour down the cost path, what’s a sponsor to do when an AdComm’s discussion of the data starts …

Spiraling Out Of Control?
If the panel’s conversation has gone awry at some point after the sponsor’s presentation, the best a company can hope for is that the meeting agenda includes an upcoming break, said PharmApprove principal Martha Arnold. “If there’s a situation where things just are spiraling out of control, and … you think perhaps the committee is dealing with information that is just plain wrong, that there’s been a misinterpretation either of your data or FDA’s data, if there’s a break you have an opportunity to at least approach the chair” and express concern, she said.

If there are no further scheduled breaks, the sponsor could pass a note to the panel’s industry representative “or tap them on the shoulder and say, ‘Hey, can you help us out here,’” said Bruce Burlington of DB Burlington Consulting, who often serves as the industry rep on AdComms. “Alternatively, if it’s really outrageous, just stand up and say, ‘Mr. Chairman, I request your permission to insert a correction in the discussion at this point.’”
It may be more problematic, however, for sponsors to insert themselves into the process of …

Question-Morphing
Anyone who has sat through at least a handful of AdComms can confirm that panelist confusion over the wording of FDA’s questions is a fact of life, often leading to discussions as to whether and how the questions should be re-written on the fly. While these question-writing “audibles” can be disconcerting for sponsors, so can the initial questions themselves.

CBI conference attendees cited tremendous variability among review divisions in the types of questions posed at AdComs, ranging from straightforward questions on risk/benefit to queries that run multiple pages and “in essence make the FDA case in the form of a question,” one conference attendee said.

FDA’s Ortwerth acknowledged room for improvement in how review divisions ask questions. “It is important that there be consistency in the way we try to communicate. … There needs to be the right way to communicate something and a clear way to communicate something and not to drive the direction of the answer.”

Even if sponsors are able to navigate all the trouble spots outlined above, they need to keep in mind that they can …

Spend Big Money, But Still Lose Big
Preparing for an AdComm involves shelling out big bucks, all of which can be for naught if a drug is decimated when it comes to the panel’s vote. MedImmune’s Cilla said his company spent approximately $900,000 on AdCom preparations for motavazimub, which included the cost of consultants, meeting space and four mock panel meetings at approximately $60,000 each. The investment resulted in a 14-3 AdComm vote against approval, which was followed by an FDA “complete response” letter and the company’s decision to withdraw the BLA.

Sanofi-Aventis Associate Vice President of Global Regulatory Affairs Kevin Malobisky said his company spent about $1.3 million preparing for one meeting that resulted in a 14-0 vote against approval – an apparent reference to the unsuccessful June 2007 AdComm for the obesity drug Zimulti (rimonabant).

Were IN VIVO Blog writing an AdComms for Dummies manual, we might put it this way: it's expensive and a lot of work to prep for an AdComm, but you have to do it. Even so, there's no money-back guarantee.

Maybe we should start consulting--at least we've got a sense of humor.

Today’s FDA Advisory Committee Meeting, Brought To You By …

… FedFinancial Federal Credit Union, serving federal employees and their families in the Washington and Baltimore areas since 1935.

OK, so maybe the credit union was not the “sponsor” of Arcapta Neohaler, the chronic obstructive pulmonary drug reviewed by FDA’s Pulmonary-Allergy Drugs Advisory Committee on March 8 (the NDA sponsor is Novartis).

Nevertheless, the bottled water provided to committee members and FDA staff was courtesy of FedFinancial. The bottle’s label bore the credit union’s name and the slogan “Member Benefits Set Us Apart.” Also, included were the credit union’s toll-free phone number, website and the location of a branch office at FDA’s White Oak headquarters (Building 2, Room 1041).

As jaded attendees of FDA advisory committee meetings, the seemingly innocuous, though incongruous, presence of a promotional item struck us as odd, so we investigated further with the assistance of fellow colleagues from “The Pink Sheet."

(Full Disclosure: This reporter took a warm, unopened bottle of FedFinancial water following the Arcapta meeting because agency staff removed her personal bottle of water during their aggressive clean-up efforts of the White Oak Conference Center.)

Similarly labeled FedFinancial water was provided to the head table two days later at the Anesthetic and Life Support Drugs Advisory Committee’s March 10 meeting on pediatric use of sedative/anesthetic agents. Both the Pulmonary-Allergy and Anesthetic-Life Support committee meetings were held at FDA’s White Oak campus.

In contrast, the Peripheral and Central Nervous System Drugs Advisory Committee convened at the Hilton in Silver Spring, Md., on March 10 to discuss a monotherapy indication for GlaxoSmithKline’s anti-seizure drug Lamictal XR. No FedFinancial water for that meeting, however, as committee members and FDA staff had to make do with pitchers of water provided by the hotel.

So, what gives? In these desperate fiscal times, is FDA so tight on funding that it has turned to financial institutions to help defray costs of holding advisory committee meetings?

Not so, the agency says. In response to a question from “The Pink Sheet,” the CDER trade press office had this explanation:

“The water bottles just happened to be left over from a function within CDER in which the credit union, which has a branch on campus for employees, supplied water. The credit union did not (at least not intentionally) provide water to staff and panel members for last week’s meetings.”

So, that’s that. And yet, we can’t seem to let this go, because seeing high-level staff in FDA’s Office of Drug Evaluation II and the Division of Pulmonary, Allergy and Rheumatology Products swilling FedFinancial water gave us an idea.

What if FDA were to offer promotional opportunities during the course of its advisory committee meetings? Oh, we’re not talking about allowing Boehringer Ingelheim and Pfizer to advertise their COPD drug Spiriva during the committee’s review of Arcapta, as that would be an obvious conflict.

Instead, why not offer non-pharma companies, such as vendors or service providers, an opportunity to sponsor ads or “commercial breaks” in the meetings? We can see it now:

A full-page ad, attached to the meeting agenda, highlighting the Silver Spring Hilton’s banquet facilities as the perfect place for that Fall 2011 wedding reception.

The panel chairman’s announcement of the mid-morning meeting break: “The morning break is sponsored by Roto Rooter Plumbing and Drain Service, where their motto is ‘And away go troubles down the drain.’”

Or, “The voting results on Arcapta’s efficacy and safety are brought to you by the international accounting firm Ernst & Young. Ernst & Young – Quality in Everything We Do.”

Then again, the text of voting questions and the electronic voting process itself tend to cause so much confusion among advisory committee members that no reputable accounting firm might want its name attached to the process.

We’ll keep working on this one while we sip our FedFinancial water.

Wolfe vs. Rappaport: A Standoff Between FDA and One of Its Advisory Committee Members

There was some disharmony at Jazz Pharmaceuticals’ FDA panel review of its drug Rekinla for fibromyalgia.

FDA’s Arthritis Drugs Advisory Committee and Drug Safety & Risk Management Advisory Committee voted 20-2 against recommending Rekinla (sodium oxybate) for a supplemental indication for treatment of fibromyalgia on August 20; sodium oxybate is currently approved for the reduction of daytime sleepiness and cataplexy in patients with narcolepsy under the trade name Xyrem. (See our coverage in "The Pink Sheet" DAILY, here.)

Anyone that has been to an FDA panel meeting knows there are ebbs and flows that contribute to the final outcome.

One of those critical points came in the late morning during the FDA question and answer session, following the agency’s formal presentations.

Enter Drugs Safety & Risk Management committee member and outspoken drug industry critic Sidney Wolfe (director of Public Citizen’s Health Research Group). Wolfe explained that he had obtained publicly available documents that cast negative light on the trustworthiness of the sponsor to responsibly market Rekinla if the panel delivered a positive recommendation and FDA approved the drug.

To resolve parallel criminal and civil allegations of off-label marketing for Xyrem by their Orphan Medical division, Jazz entered a guilty plea and paid $20 million in monetary penalties as part of a settlement with the US Attorney’s Office for the Eastern District of New York. (To view the press release, click here).

Committee Chair Kathleen O’Neill (University of Oklahoma College of Medicine) tried to cut Wolfe off, saying the session was only for questions to FDA and could only address the material in front of the panel on that day.

Wolfe continued to read a summary of the off-label marketing settlement and said he eventually would have a question.

With Wolfe unwilling to stop reading, FDA took the seemingly unprecedented action of cutting off Wolfe’s microphone. That step has become routine during the open public hearing where there is a time limit but this was one of their own advisory committee members.

Wolfe turned the microphone back on and finally got to his question: Why, he asked, did FDA not mention the Xyrem off-label settlement in its presentations to the committee? After all, he argued, it was relevant to the decision at hand: could the sponsor be trusted to market Xyrem—also known as gamma-hydroxybutyrate (GHB)—to a much broader indication than it was already approved for?

FDA Division of Anesthesia & Analgesia Products Bob Rappaport stepped in and first instructed Wolfe to stop talking when the panel chair requests that he stop talking, explaining that it was her prerogative.

Rappaport continued that Wolfe’s reading of the documents were the first time he had ever heard of the off-label case and that it was not relevant to the Rekinla review despite the fact that both Xyrem and Rekinla are the same drug (sodium oxybate). Rappaport then admonished Wolfe for not providing the documents to FDA earlier, noting that he had called FDA's advisory committee management staff earlier in the week to raise an issue, but not provided the information he was reading at the meeting.

[UPDATE: Wolfe tells us "I had never previously told FDA officials that I had obtained these documents since I assumed, as it turned out incorrectly, that they were aware of them because FDA's Office of Criminal Investigation had been involved in the criminal prosecution. Why they were unaware, as Rappaport said, is another issue."]

The drama appeared to have come to a close with Rappaport’s comments; however, the FDA official returned after the lunch break and the open public hearing with a prepared statement:

“The issue that Dr. Wolfe raised this morning is a matter related to compliance and is not related to the topic under discussion today, unless there has been an accusation of data integrity problems with this application – and I’m not aware of any data integrity concerns. The only other way that the case referred to by Dr. Wolfe could be pertinent to this application would be if it was brought up to impugn the sponsor in the hopes that the committee would be punitive towards them in your deliberations and recommendations regarding this application. However it is important for you to recognize that that would not really be punitive to the sponsor but would really be punitive to the patients.”

At that point, Jazz Pharmaceuticals' Chief Compliance Officer Janne Wissel added a few remarks.

"We do have a corporate integrity agreement because we assumed responsibility for the acts of Orphan Medical at the time we purchased the company. The Department of Justice, as well as the OIG concluded at the end of their investigation that the behaviors of Jazz Pharmaceutical were not the same as those of Orphan Medical. However, we assumed responsibility for those actions.

"We have completed three years under our corporate integrity agreement where we have reports that are based on information and an audit conducted by an independent review organization with respect to our compliance for promoting our product within our labeling. All of those reports have concluded that we are promoting our product within labeling and that we are compliant with respect to the aspects of our corporate integrity agreement."

Wolfe was not given an opportunity to respond at the meeting, so we asked him if he would care to after the fact. He emailed us the following statement:

The previous RiskMap program and the Xyrem Success Program, that were agreed upon in 2002 by Orphan as a condition of approval of Xyrem for narcolepsy, included extremely restricted distribution through one pharmacy, education of doctors and patients and a registry of patients getting the drug.

One of the questions our advisory committee was being asked to respond to was the adequacy of the new REMS program for the expanded use of oxybate for treating fibromyalgia .

Xyrem’s manufacturer, Orphan, violated the above mentioned restrictions on distribution by illegal, criminal off-label marketing and was successfully prosecuted for this. When I discovered this, a week before the hearing, I assumed that the reason why it was not included in the Advisory Committee’s briefing materials was that for some reason the FDA did not want us to know about it. This seemed peculiar, since the prosecution of the company seemed quite relevant to our evaluation of whether the new REMS program could be expected to be effective.

As I asked in my question to FDA, following the material I read from the US Attorney’s prosecution of Orphan, Why didn’t the agency provide the material to us?

Dr. Rappaport’s surprising answer was that they were not aware of the criminal prosecution. He later added that this was really a matter involving FDA compliance and that it was not “related” to the issues being discussed by the committee because it did not involve data integrity.

Although it is the compliance part of FDA that was involved in investigating this (the FDA Office of Criminal investigation was also involved), the idea that the details of this criminal prosecution involving violations of the agreed-upon restricted marketing of this dangerous drug were not relevant to our deliberations seems irrational.

Dr. Rappaport went on to say that since it was not relevant to our discussion, the only reason I brought it up was to “impugn the sponsor” and thereby turn the vote against them. This would, he said, “not really be punitive to the sponsor but would
really be punitive to the patients.”

Following Dr. Rappaport’s after-lunch statement, Jazz Pharmaceutical, the owner of Orphan since June, 2005—including, according to the US Attorney, for at least seven months while the illegal activities were occurring--stated to the Advisory committee that the company had been essentially exonerated by the US Attorney’s office and was under a corporate integrity agreement with the HHS Inspector General. This statement, like Dr. Rappaport’s, is also incorrect since, in its non-prosecution agreement with Jazz, the US attorney stated on July 13, 2007:

“Based on the evidence gathered during this investigation, the government maintains that it would be able to prove that JPI [Jazz Pharmaceutical Incorporated], as a consequence of the criminal conduct committed by its subsidiary Orphan ("the Unlawful Conduct"), is likewise guilty of introducing and causing the introduction of a misbranded drug into interstate commerce, in violation of 21 U.S.C. 331(a) and 333(a)(2).”

It’s unclear how much of an impact the Wolfe-Rappaport discussion had on the final 20-2 negative vote for Jazz. But it’s clear the public disagreement was a notable turning point in the panel deliberations.

The agency later said “the issue raised this morning by Dr. Sidney Wolfe related to Jazz Pharmaceuticals marketing practices and compliance activities for sodium oxybate is not related to the topic (that was) under discussion. The FDA weighs all of the comments made by committee members equally but will only be considering the safety and efficacy information discussed today as it evaluates sodium oxybate to treat patients with fibromyalgia.”

Avandia: It's All About Question 7

Today, FDA released an army of briefing documents ahead of the advisory committee re-review of GlaxoSmithKline's diabetes drug Avandia (rosiglitazone). To read all of the documents for yourself, click here.

While one could argue that any number of issues will be key in helping FDA determine what regulatory action to take on Avandia, we believe the key to the whole debate is quite simple, actually: question 7.

FDA asked the joint Endocrinologic & Metabolic and Drug Safety & Risk Management Advisory Committees a large number of questions--six of which are formal voting questions with multiple options.

Most of the headline attention will be focused on question 8: "What regulatory action does the panel recommend FDA take on Avandia? A) Allow continued marketing and revise the current label to remove the boxed warning and other warnings regarding risk of ischemic CV events, or B)Allow continued marketing and make no changes to the current label, or C) Allow continued marketing and revise the current label to add warnings, or D) Allow continued marketing, revise the current label and add additional restrictions on use, or E) Withdrawal from the US market."

But none of the questions may be more important to FDA decision makers than the preceding question, number 7:

"Rosiglitazone and other oral anti-diabetic therapies share the same indication of improving glycemic control in patients with Type-2 diabetes. Based on the available data, please discuss the benefit-to-risk profile of rosiglitazone in the context of other available anti-diabetic therapies."

In other words, does Avandia provide a unique benefit over existing therapies on the market? Our bet is that FDA decision makers will be paying particularly close attention to the answers provided by committee members to question 7.

FDA knows what its regulatory options are when it comes to Avandia. But the agency will be looking for arguments--even if they are in the minority--that make the case for a unique Avandia benefit over everything else.

It will be a difficult argument to make.
