A <a href=\"https:\/\/www.wsj.com\/opinion\/replimune-melanoma-rp1-fda-vinay-prasad-marty-makary-a45fa5bf\" target=\"_blank\" rel=\"noopener\">Wall Street Journal editorial<\/a> assailed the ruling, noting that it \u201cwill have a chilling effect on drug development.\u201d<\/p>\n<p>Despite the benefit to some patients, oncologists and pharmaceutical industry analysts say there were legitimate concerns about the treatment, called RP1, that may have led the FDA to reject it in any event. The company, they noted, had ignored repeated FDA suggestions that it change the design of the trial used to seek approval for the medication.<\/p>\n<p>The FDA\u2019s decision would have raised few eyebrows before the current administration took power. But Marty Makary, who took charge as commissioner 13 months ago, altered the agency\u2019s culture and damaged the trust it had built over decades while regulating 20% of U.S. consumer spending, said Steven Grossman, a regulatory consultant and former Health and Human Services official.<\/p>\n<p>\u201cPeople have to speculate about the standards and processes by which the agency makes decisions,\u201d he said. \u201cAnd that uncertainty is bad for everybody \u2014 patients and sponsors and investors.\u201d<\/p>\n<p>Under Makary \u2014 who resigned this week \u2014 senior officials have <a href=\"https:\/\/www.statnews.com\/2026\/02\/11\/moderna-flu-vaccine-application-rejected-by-prasad-overruling-fda-staff\/\" target=\"_blank\" rel=\"noopener\">either suppressed<\/a> or <a href=\"https:\/\/www.npr.org\/sections\/shots-health-news\/2026\/01\/22\/nx-s1-5684294\/leucovorin-autism-folic-folinic-acid-origins-vitamin-b\" target=\"_blank\" rel=\"noopener\">pushed forward<\/a> some <a href=\"https:\/\/www.fda.gov\/news-events\/press-announcements\/fda-approves-first-treatment-patients-cerebral-folate-transport-deficiency\" target=\"_blank\" rel=\"noopener\">drug approvals<\/a> <a href=\"https:\/\/www.whitehouse.gov\/presidential-actions\/2026\/04\/accelerating-medical-treatments-for-serious-mental-illness\/\" target=\"_blank\" rel=\"noopener\">and policies<\/a> at the behest <a href=\"https:\/\/www.fda.gov\/news-events\/press-announcements\/fda-approves-first-treatment-patients-cerebral-folate-transport-deficiency\" target=\"_blank\" rel=\"noopener\">of President Donald Trump or HHS Secretary Robert F. Kennedy Jr., ignoring the advice of agency professionals. In defending his actions, Makary often eschewed the agency\u2019s traditionally measured language about its decisions.<\/p>\n<p>In response to criticism for rejecting the melanoma treatment, for example, Makary accused its manufacturer, Replimune, of \u201ccorruption,\u201d saying it was \u201cengaging in corporate spin\u201d to make the FDA look bad.<\/p>\n<p>\u201cI don\u2019t work for Replimune. I work for the American people,\u201d Makary said in a May 5 interview on CNBC. Kennedy backed him up during a congressional budget hearing in which Kennedy mistakenly claimed that patients in Replimune\u2019s clinical trial had also received chemotherapy.<\/p>\n<p>Makary did not respond to requests for comment.<\/p>\n<p>\u201cAll the norms have been thrown out the window, so we don\u2019t know what underlines an agency decision,\u201d said <a href=\"https:\/\/thehill.com\/business-a-lobbying\/2578-from-kennedys-foot-soldier-to-lobbyist-kim-tells-his-story\/\" target=\"_blank\" rel=\"noopener\">Paul Kim<\/a>, a former FDA staffer and Senate aide to Sen. Edward Kennedy who\u2019s now a pharmaceutical industry consultant in Boston. \u201cEven when there are legitimate scientific and regulatory reasons why a drug will not be approved, we\u2019re left guessing whether it\u2019s legitimate grounds or just a political play.\u201d<\/p>\n<div class=\"wp-block wp-block-kff-shared-newsletter  wp-block-kff-shared-newsletter--background-white\" data-type=\"kff-shared\/newsletter\" data-align=\"center\">\n<div class=\"wp-block-kff-shared-newsletter__container\">\n<div class=\"wp-block-kff-shared-newsletter__content\">\n<div class=\"wp-block-kff-shared-newsletter__text\">\n<h4 class=\"newsletter__title\">\n\t\t\t\t\tEmail Sign-Up\t\t\t\t<\/h4>\n<p class=\"newsletter__description\">\n\t\t\t\t\tSubscribe to KFF Health News&#8217; free weekly newsletter, &#8220;The Week in Brief.&#8221;\t\t\t\t<\/p>\n<\/p><\/div>\n<\/p><\/div>\n<\/p><\/div>\n<\/div>\n<p><strong>A Doomed Cancer Drug<\/strong><\/p>\n<p>Melanoma is the fifth most commonly diagnosed cancer in the United States, with about 112,000 new cases each year. The American Cancer Society projects that <a href=\"https:\/\/www.cancer.org\/cancer\/types\/melanoma-skin-cancer\/about\/key-statistics.html\" target=\"_blank\" rel=\"noopener\">about 8,500 people will die<\/a> from melanoma this year in the U.S. If Replimune\u2019s treatment, RP1, worked as well as it did in the clinical trial, Whitman said, as many as 2,500 of those patients could be saved.<\/p>\n<p>RP1 is a genetically engineered virus designed to destroy tumor cells and alert the immune system to swing into action against them. Replimune sought accelerated approval \u2014 a sort of shortcut that allows a product to enter the market while a larger confirmatory trial takes place \u2014 by presenting data that showed a third of 140 people in the trial had their tumors shrink or disappear. But the agency had warned Replimune in July that it risked denial unless it changed its development plans. In particular, the FDA noted that the trial had no control arm to compare RP1 to an approved melanoma treatment. Instead, all patients were given RP1 along with Opdivo, a type of immunotherapy.<\/p>\n<p>Replimune\u2019s scientists don\u2019t entirely understand how the drug works, but research indicates that, in addition to destroying cancer cells, it releases chemicals that revive Opdivo\u2019s capacity to stimulate the immune system. The company argued it would be unethical to give Opdivo alone as a control arm, because all the patients entered in the trial had already stopped getting better while taking only Opdivo or other drugs in its class.<\/p>\n<p>\u201cHaving a control arm would have been unethical,\u201d Wise-Draper said. Some of her patients responded extremely well to RP1 and no longer have evidence of melanoma, she said.<\/p>\n<p>Replimune currently has a larger trial that includes a control arm, but \u201cthe bigger question is whether the company will survive,\u201d Whitman said. The FDA-accelerated approval would have persuaded investors to provide enough cash to finish the larger trial, he said.<\/p>\n<p>Replimune did not respond to repeated requests for comment. But <a href=\"https:\/\/www.fiercebiotech.com\/biotech\/replimune-sheds-60-staff-after-fda-rejection-vows-continue-operations\" target=\"_blank\" rel=\"noopener\">the company told reporters<\/a> it is firing more than half its staff and closing some operations in the wake of the FDA ruling.<\/p>\n<p>RP1 wouldn\u2019t have been the first melanoma drug approved based on a single-arm trial. Keytruda, the best-selling Merck cancer drug, was approved to treat melanoma some 12 years ago based on such a trial design. But in its denial statement, the FDA said it wasn\u2019t convinced that the positive effects of the combination regimen were all due to RP1 and not partly to Opdivo.<\/p>\n<p>Replimune arguably could have found an ethical way to set up a control arm for its treatment, Kim said. On the other hand, the FDA could have \u201cgiven them a provisional yes\u201d with accelerated approval, he said. The whole point of the three-decade-old accelerated approval program is to \u201ctake a gamble,\u201d Kim said. The agency\u2019s statement, stressing the company\u2019s methodology over the result, \u201cis a recalibration of how confident sponsors can be with similar studies,\u201d he said.<\/p>\n<p><strong>Vinay Prasad\u2019s Final Days at FDA<\/strong><\/p>\n<p>Much of the criticism of the FDA under Trump has focused on Vinay Prasad, who was fired then rehired last summer and held various leadership roles at the agency. Prasad, an oncologist known for critiquing the statistical bases of studies, repeatedly intervened in approval processes for drugs and vaccines normally decided by lower-ranking FDA professionals.<\/p>\n<p>Prasad, who did not respond to requests for comment, resigned for good May 1, three weeks after the Replimune decision. \u201cThere\u2019s this lingering question of whether this was Vinay\u2019s last stand, or an objective decision made by careful scientists,\u201d Kim said.<\/p>\n<p>Makary ran afoul of Trump administration officials over various decisions, the last being his reluctance to approve flavored vapes for smoking cessation. Trump\u2019s anti-abortion supporters wanted him ousted for allowing a generic form of mifepristone on the market, and for failing to speed up studies they hoped would lead to the abortion drug\u2019s withdrawal from the market.<\/p>\n<p>But in the industries regulated by the FDA, ranging from gene therapy to vaccines and cancer, officials are frustrated by the agency\u2019s uncertain direction. In past administrations, the agency generally swung on a narrow arc between loosening and tightening requirements for drug approvals. Under Makary, \u201cit\u2019s been swinging in every conceivable direction,\u201d Grossman said.<\/p>\n<p>\u201cIt\u2019s very inconsistent; it\u2019s all over the place,\u201d Whitman said. \u201cThe inconsistency is part of the concern.\u201d<\/p>\n<p>During his tenure, Makary made a series of categorical statements that either claim credit for progress made during earlier administrations or exaggerate the agency\u2019s ability to move forward on goals.<\/p>\n<p>For example, he set a goal of <a href=\"https:\/\/www.fda.gov\/news-events\/press-announcements\/fda-announces-plan-phase-out-animal-testing-requirement-monoclonal-antibodies-and-other-drugs\" target=\"_blank\" rel=\"noopener\">ending animal testing<\/a>, which is considered impractical at the moment, Kim said, and moved to <a href=\"https:\/\/www.fda.gov\/news-events\/press-announcements\/fda-announces-completion-first-ai-assisted-scientific-review-pilot-and-aggressive-agency-wide-ai\" target=\"_blank\" rel=\"noopener\">aggressively implement<\/a> artificial intelligence at the FDA \u2014 prematurely, critics say. Makary and Prasad also promised to reduce the <a href=\"https:\/\/www.nejm.org\/doi\/abs\/10.1056\/NEJMsb2517623\" target=\"_blank\" rel=\"noopener\">standard number of required clinical trials<\/a> from two to one. FDA statutes require two well-controlled clinical trials for drug approvals, but exceptions to that rule are already frequent.<\/p>\n<p>\u201cThe FDA is sending signals that it wants to even further reduce the evidence needed to support drug approval,\u201d said Aaron Kesselheim, a Harvard Medical School professor and an expert on the drug industry. \u201cOf course, if we\u2019re talking about vaccines, the total opposite is the case. FDA has been taking real steps to make it harder to get vaccines approved.\u201d<\/p>\n<p>The FDA fired about 4,000 staffers at the start of the Trump administration. Makary promised to hire thousands back, but considering the upheavals at HHS and the FDA, these positions may be hard to fill. \u201cWhat magic trick will get that done?\u201d Grossman asked.<\/p>\n<p>\u201cThe unfortunate thing is that there has been so much chaos at FDA that this Replimune decision, which may have needed to happen, has gotten mired in the controversy,\u201d said Evan Seigerman, leader of healthcare research at BMO Capital Markets.<\/p>\n<\/div>\n<p><br \/>\n<br \/><a href=\"https:\/\/kffhealthnews.org\/health-industry\/fda-blocked-melanoma-drug-marty-makary-confusion-reigned\/\" target=\"_blank\" rel=\"noopener\">Source link <\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The FDA\u2019s recent decision to withhold approval of a new skin cancer treatment fell like a hammer on doctors who treat melanoma and patients who saw that the drug had prolonged the lives of a third of the participants in a clinical trial. \u201cIt was devastating news,\u201d said Trisha Wise-Draper, a dermatologist at the University [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":37989,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":"","jetpack_publicize_message":"","jetpack_publicize_feature_enabled":true,"jetpack_social_post_already_shared":true,"jetpack_social_options":{"image_generator_settings":{"template":"highway","default_image_id":0,"font":"","enabled":false},"version":2}},"categories":[171],"tags":[],"class_list":["post-37988","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-health-conditions"],"jetpack_publicize_connections":[],"_links":{"self":[{"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/posts\/37988","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=37988"}],"version-history":[{"count":1,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/posts\/37988\/revisions"}],"predecessor-version":[{"id":37990,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/posts\/37988\/revisions\/37990"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=\/wp\/v2\/media\/37989"}],"wp:attachment":[{"href":"https:\/\/pickbydoc.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=37988"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=37988"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pickbydoc.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=37988"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
