In the U.S., 1 in 9 people over the age of 65 have Alzheimer's disease, but there still aren't any available treatments for this progressive and ultimately fatal disease.

Investigators also gave Alzheimer's disease patients cognitive tests to see if simufilam actually made a difference, but they couldn't measure an improvement.</p>\n<p><b>2. Ocugen</b></p>\n<p>Shares of this clinical-stage drugmaker have been soaring in response to good news for a COVID-19 vaccine called Covaxin. The vaccine's developer, Bharat Biotech, is a well-established vaccine manufacturer headquartered in India.</p>\n<p>Bharat Biotech has hired Ocugen to co-develop Covaxin for the U.S. market, and it looks like a winner. In a phase 3 study with over 25,000 volunteers, Covaxin was about 81% effective at preventing COVID-19 infections in India.</p>\n<p>Before buying any Ocugen shares, you should know that the FDA wasn't willing to consider emergency use authorization requests without data from lots of U.S. trial volunteers when there were zero COVID-19vaccines available. Now that the agency has already authorized three safe and effective options, there's zero chance that Ocugen will sell Covaxin in the U.S. without a new phase 3 trial.</p>\n<p><b>3. Rubius Therapeutics</b></p>\n<p>This clinical-stage biotech is developing new cancer therapies made from a line of red blood cells that can be taken off a shelf and administered as soon as they're prescribed. Shares of Rubius have soared this year, thanks to some tumor shrinkage observed in an early-stage study with a variety of cancer patients taking its lead candidate RTX-240.</p>\n<p>In an interim assessment of an ascending-dosage trial that had data from 16 volunteers available, two of the patients have responded well to RTX-240 treatment. While this looks like a pretty good result for an interim analysis of an early trial, it's probably too early for anyone at Rubius to begin celebrating. That's because the only confirmed tumor shrinkage presented so far occurred for a patient treated with the lowest dosage tested.</p>\n<p>Rubius Therapeutics' red blood cells are engineered to excite and enlist different types of white blood cells to take action against tumors. The company was able to show expansion of natural killer cells and T-cells for eight patients earlier this year. Unfortunately, the company hasn't been able to show RTX-240 expanded these tumor-fighting cells for the patients who responded.</p>\n<p><b>Looking forward</b></p>\n<p>All of these companies have huge market valuations right now that could come crashing down if their lead programs can't deliver. That's because there's nearly nothing for them to fall back on.</p>\n<p>Ocugen doesn't have any potential new drugs in clinical trials right now, and it's going to be a long time before we know if the gene therapies it intends to develop have a shot at success. Cassava Sciences has a potential new test for biomarkers that could indicate Alzheimer's disease, but simufilam is the only clinical-stage new drug candidate in its pipeline.</p>\n<p>Rubius Therapeutics is developing a platform of red-blood-cell-based treatments, and the company already has a second candidate cleared by the FDA to begin clinical trials. If any of these companies has a fallback if its lead candidate doesn't work out, it's Rubius. That said, it's still way too risky to consider putting in your portfolio at the moment.</p>","collect":0,"html":"<!DOCTYPE html>\n<html>\n<head>\n<meta http-equiv=\"Content-Type\" content=\"text/html; charset=utf-8\" />\n<meta name=\"viewport\" content=\"width=device-width,initial-scale=1.0,minimum-scale=1.0,maximum-scale=1.0,user-scalable=no\"/>\n<meta name=\"format-detection\" content=\"telephone=no,email=no,address=no\" />\n<title>3 Biotech Stocks to Avoid Right Now</title>\n<style type=\"text/css\">\na,abbr,acronym,address,applet,article,aside,audio,b,big,blockquote,body,canvas,caption,center,cite,code,dd,del,details,dfn,div,dl,dt,\nem,embed,fieldset,figcaption,figure,footer,form,h1,h2,h3,h4,h5,h6,header,hgroup,html,i,iframe,img,ins,kbd,label,legend,li,mark,menu,nav,\nobject,ol,output,p,pre,q,ruby,s,samp,section,small,span,strike,strong,sub,summary,sup,table,tbody,td,tfoot,th,thead,time,tr,tt,u,ul,var,video{ font:inherit;margin:0;padding:0;vertical-align:baseline;border:0 }\nbody{ font-size:16px; line-height:1.5; color:#999; background:transparent; }\n.wrapper{ overflow:hidden;word-break:break-all;padding:10px; }\nh1,h2{ font-weight:normal; line-height:1.35; margin-bottom:.6em; }\nh3,h4,h5,h6{ line-height:1.35; margin-bottom:1em; }\nh1{ font-size:24px; }\nh2{ font-size:20px; }\nh3{ font-size:18px; }\nh4{ font-size:16px; }\nh5{ font-size:14px; }\nh6{ font-size:12px; }\np,ul,ol,blockquote,dl,table{ margin:1.2em 0; }\nul,ol{ margin-left:2em; }\nul{ list-style:disc; }\nol{ list-style:decimal; }\nli,li p{ margin:10px 0;}\nimg{ max-width:100%;display:block;margin:0 auto 1em; }\nblockquote{ color:#B5B2B1; border-left:3px solid #aaa; padding:1em; }\nstrong,b{font-weight:bold;}\nem,i{font-style:italic;}\ntable{ width:100%;border-collapse:collapse;border-spacing:1px;margin:1em 0;font-size:.9em; }\nth,td{ padding:5px;text-align:left;border:1px solid #aaa; }\nth{ font-weight:bold;background:#5d5d5d; }\n.symbol-link{font-weight:bold;}\n/* header{ border-bottom:1px solid #494756; } */\n.title{ margin:0 0 8px;line-height:1.3;color:#ddd; }\n.meta {color:#5e5c6d;font-size:13px;margin:0 0 .5em; }\na{text-decoration:none; color:#2a4b87;}\n.meta .head { display: inline-block; overflow: hidden}\n.head .h-thumb { width: 30px; height: 30px; margin: 0; padding: 0; border-radius: 50%; float: left;}\n.head .h-content { margin: 0; padding: 0 0 0 9px; float: left;}\n.head .h-name {font-size: 13px; color: #eee; margin: 0;}\n.head .h-time {font-size: 11px; color: #7E829C; margin: 0;line-height: 11px;}\n.small {font-size: 12.5px; display: inline-block; transform: scale(0.9); -webkit-transform: scale(0.9); transform-origin: left; -webkit-transform-origin: left;}\n.smaller {font-size: 12.5px; display: inline-block; transform: scale(0.8); -webkit-transform: scale(0.8); transform-origin: left; -webkit-transform-origin: left;}\n.bt-text {font-size: 12px;margin: 1.5em 0 0 0}\n.bt-text p {margin: 0}\n</style>\n</head>\n<body>\n<div class=\"wrapper\">\n<header>\n<h2 class=\"title\">\n3 Biotech Stocks to Avoid Right Now\n</h2>\n\n<h4 class=\"meta\">\n\n\n2021-03-18 20:24 GMT+8 <a href=https://www.fool.com/investing/2021/03/18/3-biotech-stocks-to-avoid-right-now/><strong>Motley Fool</strong></a>\n\n\n</h4>\n\n</header>\n<article>\n<div>\n<p>Here's why these attention-grabbing stocks could be toxic to your portfolio.\n\nDid you know that newbiotech stocksgo public at a rate of about one per week?
