NEW YORK (AP) -- Pfizer Inc. said Friday it is pulling its blood pressure drug Thelin off the market and stopping all clinical trials because the drug can cause fatal liver damage.
 Thelin is sold in the European Union  Canada  and Australia as an oral treatment for severe pulmonary arterial hypertension  or high blood pressure in the pulmonary artery. Pfizer said a review of data from clinical trials and post-marketing reports showed a new link to liver injury. It also consulted with experts about the link between Thelin and the deaths of two patients.
 Liver damage was a known side effect of Thelin and similar drugs  the company said. Pfizer said the withdrawal was voluntary and added that it has withdrawn its filing for marketing approval in the U.S.
 Since there are other treatment options  Pfizer said the benefits of Thelin don't outweigh the risks. It is stopping all studies of the oral drug  which Pfizer acquired in 2008 when it bought Encysive Pharmaceuticals Inc. Encysive had been trying to win marketing approval for Thelin since 2005  but the Food and Drug Administration said it was not effective enough. Other agencies only approved the drug for hypertension that was so debilitating that patients' physical activity was severely limited.
 The chemical name of Thelin is sitaxsentan.

10 Things You Did n't Know About Ted Cruz .

Fellinger pointed us to video posts of the CVA events showing that Cruz each time took questions via a moderator , who recognized a few individuals to speak directly to Cruz . 
But could it be that U.S. Sen. Ted Cruz does n't get personally grilled by constituents very often ? 
Cruz , poised to seek re-election as Texas ' junior Republican senator in 2018 , hardly has a reputation for avoiding attention . 
A Concerned Veterans for America spokesman , Jim Fellinger , told us each CVA event with Cruz was open to the public by registration , without the group screening out anybody who registered . 
Regardless , the Houston lawyer was told during the 2017 Texas Tribune Festival about a Democratic challenger 's suggestion that Cruz had n't visited small Texas towns during the term he won in 2012 .

The events Cruz attended from April through August demonstrate that the term "town hall" can be stretched every which way , even to events not open to the public . 
All told , it looks to us as if Cruz took questions at gatherings of selected constituents , mostly business employees , with the three veterans events open to members of the public who registered . 
We wondered about that , finding that Cruz 's count largely turned on one 's definition of "town hall ." 
Next , we spoke with several experts about whether Cruz 's events should be considered town halls . 
A town hall , Cruz spokesman Phil Novack told us , is defined by Merriam-Webster as "an event at which a public official or political candidate addresses an audience by answering questions posed by individual members ." 
We also asked Novack to share a list of Cruz 's 2017 events in Texas that were open to the public without registration -- where anyone could ask a question on any topic . 
Ted Cruz Statement : "In 2017 , I 've done 17 town halls ." 
It seems these town halls are open only to the people from the sections of ` town ' that support Ted Cruz . 
Novack told us Cruz had held 19 town halls with Texas constituents in 2017 , all "organized by third parties who determined attendees , where" the senator "has taken unvetted questions from anyone in the crowd -- at businesses , factories , chambers of commerce , and in public venues ."
