1 00:00:08,670 --> 00:00:02,630 [Applause] 2 00:00:44,779 --> 00:00:15,080 [Music] 3 00:00:48,200 --> 00:00:44,789 this is a toxin that causes the pain 4 00:00:52,549 --> 00:00:48,210 what we do is oxidize it so it's no 5 00:00:55,910 --> 00:00:52,559 longer toxic and what we find is that 6 00:00:59,209 --> 00:00:55,920 and we find this by accident is that it 7 00:01:03,009 --> 00:00:59,219 has tremendous activity with respect to 8 00:01:05,690 --> 00:01:03,019 scarring in terms of preventing scars or 9 00:01:08,149 --> 00:01:05,700 ameliorating scars we will worry about 10 00:01:13,100 --> 00:01:08,159 the spectrum of targets we were 11 00:01:15,170 --> 00:01:13,110 interested in in this molecule as I say 12 00:01:16,999 --> 00:01:15,180 by accident because in a patient that we 13 00:01:18,590 --> 00:01:17,009 were treating using this molecule 14 00:01:20,990 --> 00:01:18,600 treating for something else we found it 15 00:01:22,550 --> 00:01:21,000 her scars disappeared her superficial 16 00:01:24,859 --> 00:01:22,560 scars are wondering how on earth could 17 00:01:28,999 --> 00:01:24,869 that possibly be so we started doing 18 00:01:31,249 --> 00:01:29,009 some big-time science and we know that 19 00:01:34,789 --> 00:01:31,259 streptomycin among other things is a 20 00:01:37,880 --> 00:01:34,799 potent anti-inflammatory agent yet down 21 00:01:40,969 --> 00:01:37,890 regulates pro-inflammatory genes that 22 00:01:43,010 --> 00:01:40,979 second one mmp9 is especially important 23 00:01:45,469 --> 00:01:43,020 over the last decade between eight and 24 00:01:47,780 --> 00:01:45,479 nine billion dollars have been spent by 25 00:01:51,020 --> 00:01:47,790 the pharmaceutical industry looking for 26 00:01:52,569 --> 00:01:51,030 products that down-regulate mmp9 because 27 00:01:54,770 --> 00:01:52,579 it's involved in so many diseases 28 00:01:56,990 --> 00:01:54,780 several of those products have made it 29 00:02:01,850 --> 00:01:57,000 to formal clinical trials and they have 30 00:02:03,950 --> 00:02:01,860 all failed because of toxicity again 31 00:02:06,920 --> 00:02:03,960 strep the licen though in our hands is 32 00:02:08,930 --> 00:02:06,930 not toxic well it down regulates the 33 00:02:11,180 --> 00:02:08,940 pro-inflammatory genes it up regulates 34 00:02:12,890 --> 00:02:11,190 the anti-inflammatory ones these we're 35 00:02:14,059 --> 00:02:12,900 not going to get into the science of but 36 00:02:16,099 --> 00:02:14,069 it's important that it 37 00:02:18,199 --> 00:02:16,109 is an anti-inflammatory product but it 38 00:02:21,140 --> 00:02:18,209 does a lot more than that one of the 39 00:02:23,349 --> 00:02:21,150 things it does is disrupt the balance 40 00:02:26,420 --> 00:02:23,359 between collagen and collagenase 41 00:02:29,479 --> 00:02:26,430 collagen is the primary protein in scars 42 00:02:31,789 --> 00:02:29,489 scars are not stable some of you have 43 00:02:33,110 --> 00:02:31,799 had scars from accidents or surgery or 44 00:02:35,330 --> 00:02:33,120 whatever that have been with you for 45 00:02:37,099 --> 00:02:35,340 decades those are changing every day 46 00:02:38,959 --> 00:02:37,109 although they look the same to you there 47 00:02:42,140 --> 00:02:38,969 there's a constant turnover of the 48 00:02:44,300 --> 00:02:42,150 collagen the collagenase the enzyme is 49 00:02:47,839 --> 00:02:44,310 breaking down old collagen new collagen 50 00:02:51,199 --> 00:02:47,849 is being is replacing the old we upset 51 00:02:53,569 --> 00:02:51,209 the balance in favor of collagenase so 52 00:02:57,580 --> 00:02:53,579 that the old collagen is broken down and 53 00:03:01,789 --> 00:02:57,590 it's replaced by more vital tissue we 54 00:03:05,500 --> 00:03:01,799 have we started with looking at a series 55 00:03:08,990 --> 00:03:05,510 of superficial scars and we found that 56 00:03:11,899 --> 00:03:09,000 external scars would all respond to slo 57 00:03:13,819 --> 00:03:11,909 therapy this is just a kind of an 58 00:03:18,409 --> 00:03:13,829 example of some of the types of scars 59 00:03:20,869 --> 00:03:18,419 that we looked at here's a more graphic 60 00:03:23,300 --> 00:03:20,879 example this is a face of a girl that 61 00:03:25,789 --> 00:03:23,310 just went through the windshield if you 62 00:03:29,809 --> 00:03:25,799 look closely and get oriented you can 63 00:03:33,469 --> 00:03:29,819 see there's her chin her teeth her nose 64 00:03:37,429 --> 00:03:33,479 has been torn off and displaced so she's 65 00:03:38,809 --> 00:03:37,439 in trouble this is her in the emergency 66 00:03:41,599 --> 00:03:38,819 room at the Medical University of South 67 00:03:43,069 --> 00:03:41,609 Carolina in in Charleston 68 00:03:46,099 --> 00:03:43,079 you can see she's gonna have a bit of a 69 00:03:47,270 --> 00:03:46,109 scar on her left cheek her nose is back 70 00:03:49,219 --> 00:03:47,280 in place there's gonna be some serious 71 00:03:50,719 --> 00:03:49,229 scarring there look at the angle of that 72 00:03:52,490 --> 00:03:50,729 tube it's ripped out the corner of her 73 00:03:55,099 --> 00:03:52,500 mouth gonna be some scars there and 74 00:03:58,789 --> 00:03:55,109 across her eyebrow also so she's gonna 75 00:04:01,520 --> 00:03:58,799 look like a pirate okay her mother was a 76 00:04:03,949 --> 00:04:01,530 nurse she started right away a nurse 77 00:04:06,099 --> 00:04:03,959 with us she got to the mother got to the 78 00:04:11,839 --> 00:04:06,109 emergency room started a solo therapy 79 00:04:14,659 --> 00:04:11,849 and there she is three weeks later and 80 00:04:18,949 --> 00:04:14,669 here she is a month after that last 81 00:04:20,870 --> 00:04:18,959 picture now you can see there's still a 82 00:04:22,670 --> 00:04:20,880 scar there that's going away it's not 83 00:04:24,950 --> 00:04:22,680 nearly what you might expect little or 84 00:04:26,060 --> 00:04:24,960 no scarring around the nose that corner 85 00:04:27,970 --> 00:04:26,070 of her mouth doesn't look too bad 86 00:04:32,730 --> 00:04:27,980 compared to what it did before 87 00:04:35,680 --> 00:04:32,740 jeez the good that'll be the next slide 88 00:04:38,140 --> 00:04:35,690 the point of all this is the important 89 00:04:40,900 --> 00:04:38,150 point is that nothing was given to her 90 00:04:43,120 --> 00:04:40,910 topically all right this is all systemic 91 00:04:44,710 --> 00:04:43,130 so there's nothing rubbed on her skin to 92 00:04:47,500 --> 00:04:44,720 make the scar go away or to prevent the 93 00:04:49,570 --> 00:04:47,510 scar so being clever scientists that we 94 00:04:51,220 --> 00:04:49,580 are we wondered well gosh if this is 95 00:04:54,100 --> 00:04:51,230 going systemically and working on 96 00:04:56,010 --> 00:04:54,110 external scars like this gals face what 97 00:04:58,930 --> 00:04:56,020 would happen with internal scars 98 00:05:01,870 --> 00:04:58,940 well first you ask what the heck are 99 00:05:06,220 --> 00:05:01,880 internal scars these are a few of the 100 00:05:08,770 --> 00:05:06,230 ones that we've treated successfully all 101 00:05:10,960 --> 00:05:08,780 of us have internal scars all the time 102 00:05:12,400 --> 00:05:10,970 and there is what's called the collagen 103 00:05:15,970 --> 00:05:12,410 theory of aging that would suggest that 104 00:05:17,470 --> 00:05:15,980 our longevity is determined by the 105 00:05:19,690 --> 00:05:17,480 collagen that accumulates in our body 106 00:05:22,270 --> 00:05:19,700 that is as a consequence of normal 107 00:05:23,440 --> 00:05:22,280 function of the organs there's constant 108 00:05:25,600 --> 00:05:23,450 inflammation which is followed by 109 00:05:27,820 --> 00:05:25,610 collagen deposition the collagen gets 110 00:05:29,620 --> 00:05:27,830 laid down cross-linked becomes less 111 00:05:31,990 --> 00:05:29,630 elastic that's what happens with 112 00:05:33,610 --> 00:05:32,000 cardiomyopathy for example that scar 113 00:05:35,440 --> 00:05:33,620 tissue forming in the heart the heart 114 00:05:38,380 --> 00:05:35,450 becomes less efficient as a consequence 115 00:05:40,420 --> 00:05:38,390 of that scar tissue and there is less 116 00:05:42,460 --> 00:05:40,430 efficient signaling between nodes of the 117 00:05:45,250 --> 00:05:42,470 heart likewise with the kidneys and the 118 00:05:47,800 --> 00:05:45,260 and the liver and so forth surgical 119 00:05:49,960 --> 00:05:47,810 adhesions big deal we had some fun with 120 00:05:51,970 --> 00:05:49,970 some patients that had circle surgical 121 00:05:55,300 --> 00:05:51,980 adhesions following gut surgery or a 122 00:05:57,370 --> 00:05:55,310 gynecological third surgery we know that 123 00:05:59,140 --> 00:05:57,380 one of the complications after those 124 00:06:01,960 --> 00:05:59,150 kinds of surgeries is often adhesions 125 00:06:03,400 --> 00:06:01,970 and what do you do for adhesions well 126 00:06:05,410 --> 00:06:03,410 the surgeon goes back in and cuts them 127 00:06:08,680 --> 00:06:05,420 out well guess what causes more 128 00:06:11,800 --> 00:06:08,690 adhesions so if we found that we could 129 00:06:14,260 --> 00:06:11,810 give streptomycin Oh in very low 130 00:06:16,390 --> 00:06:14,270 concentrations similar to the ones that 131 00:06:18,850 --> 00:06:16,400 dr. Ives was talking about and even 132 00:06:21,670 --> 00:06:18,860 lower and those adhesions would go away 133 00:06:26,260 --> 00:06:21,680 in two weeks no more surgery that's a 134 00:06:28,510 --> 00:06:26,270 big deal question came up to us more 135 00:06:31,900 --> 00:06:28,520 recently thinking back in the girl who 136 00:06:34,480 --> 00:06:31,910 went through the windshield could SL 137 00:06:37,840 --> 00:06:34,490 will be used to treat traumatic brain 138 00:06:41,360 --> 00:06:37,850 injury now clearly that's an internal 139 00:06:42,860 --> 00:06:41,370 type of scarring if it occurs but it's 140 00:06:47,530 --> 00:06:42,870 different than anything else we've ever 141 00:06:50,270 --> 00:06:47,540 done for a couple of reasons one is 142 00:06:53,450 --> 00:06:50,280 there's a question well let's first look 143 00:06:56,480 --> 00:06:53,460 at what traumatic brain injury is by 144 00:06:58,159 --> 00:06:56,490 definition its damage either temporary 145 00:07:02,120 --> 00:06:58,169 or permanent to the brain as a 146 00:07:03,800 --> 00:07:02,130 consequence of injury they're about a 147 00:07:07,280 --> 00:07:03,810 million and a half cases in this country 148 00:07:09,760 --> 00:07:07,290 per year of those 50,000 will die an 149 00:07:13,850 --> 00:07:09,770 80,000 are going to have some degree of 150 00:07:15,830 --> 00:07:13,860 permanent disability the most likely or 151 00:07:17,480 --> 00:07:15,840 the most common causes of traumatic 152 00:07:20,810 --> 00:07:17,490 brain injury in our country are 153 00:07:27,260 --> 00:07:20,820 accidents automobile bicycle pedestrian 154 00:07:28,879 --> 00:07:27,270 accidents second probably second is in 155 00:07:30,680 --> 00:07:28,889 the military with all the different 156 00:07:33,560 --> 00:07:30,690 things that the military personnel might 157 00:07:40,460 --> 00:07:33,570 be exposed to assault or a leading cause 158 00:07:43,640 --> 00:07:40,470 also we wondered still can we do 159 00:07:46,700 --> 00:07:43,650 anything about these kinds of injuries 160 00:07:48,409 --> 00:07:46,710 and the reasons are these we know that 161 00:07:50,930 --> 00:07:48,419 from the internal and external stars 162 00:07:53,719 --> 00:07:50,940 that seem to respond so successfully to 163 00:07:57,529 --> 00:07:53,729 slo therapy that those are those scars 164 00:08:00,140 --> 00:07:57,539 are involved with with collagen which 165 00:08:02,240 --> 00:08:00,150 comes from fibroblasts there are not 166 00:08:04,310 --> 00:08:02,250 fibroblasts in the brain and there's not 167 00:08:07,070 --> 00:08:04,320 collagen in the brain instead they're 168 00:08:09,529 --> 00:08:07,080 glial cells in the brain that people 169 00:08:11,750 --> 00:08:09,539 think have something to do with brain 170 00:08:15,050 --> 00:08:11,760 what might be called brain scarring so 171 00:08:19,100 --> 00:08:15,060 it's a question of collagen versus what 172 00:08:23,029 --> 00:08:19,110 well nobody really knows what another 173 00:08:25,430 --> 00:08:23,039 problem is you can't really scan and see 174 00:08:28,610 --> 00:08:25,440 by any imaging techniques that are 175 00:08:30,939 --> 00:08:28,620 available you can't see brain scars now 176 00:08:34,940 --> 00:08:30,949 there are four or five fda-approved 177 00:08:37,730 --> 00:08:34,950 methods for brain scans but none of them 178 00:08:39,130 --> 00:08:37,740 will show what we think a scar should 179 00:08:42,050 --> 00:08:39,140 look like so you can't see 180 00:08:45,050 --> 00:08:42,060 before-and-afters that's a lot different 181 00:08:46,550 --> 00:08:45,060 than internal and external scar external 182 00:08:49,040 --> 00:08:46,560 scars like the girls face it's easy 183 00:08:50,630 --> 00:08:49,050 doesn't measure internal scars you can 184 00:08:54,319 --> 00:08:50,640 also do we've published a couple papers 185 00:08:56,269 --> 00:08:54,329 using sonography for example with 186 00:08:58,489 --> 00:08:56,279 thoroughbred horses in Kentucky that 187 00:09:00,949 --> 00:08:58,499 we've done some work with and we can see 188 00:09:04,129 --> 00:09:00,959 very clearly nice objective measurements 189 00:09:05,840 --> 00:09:04,139 about what happens with scars as a 190 00:09:07,729 --> 00:09:05,850 consequence of SLO therapy you can watch 191 00:09:10,910 --> 00:09:07,739 them go away you can measure that you 192 00:09:13,069 --> 00:09:10,920 can't do that in the brain so what do we 193 00:09:18,590 --> 00:09:13,079 do instead we're going to have to focus 194 00:09:19,999 --> 00:09:18,600 on clinical outcomes well where are we 195 00:09:20,539 --> 00:09:20,009 going to find a few patients to fool 196 00:09:25,100 --> 00:09:20,549 around with 197 00:09:27,799 --> 00:09:25,110 guess what we'll go to some NFL players 198 00:09:30,949 --> 00:09:27,809 down in the Phoenix area and see if they 199 00:09:34,160 --> 00:09:30,959 might participate we started with six 200 00:09:36,139 --> 00:09:34,170 players one of them dropped out after 201 00:09:38,960 --> 00:09:36,149 just about two months disappeared we had 202 00:09:40,970 --> 00:09:38,970 no follow-up these others we followed 203 00:09:42,549 --> 00:09:40,980 for three years now these five and 204 00:09:46,069 --> 00:09:42,559 understand it's just a tiny tiny number 205 00:09:48,079 --> 00:09:46,079 but here are the original complaints not 206 00:09:49,579 --> 00:09:48,089 all the players had all these complaints 207 00:09:52,939 --> 00:09:49,589 but this is a pretty good cross-section 208 00:09:54,139 --> 00:09:52,949 of what happened it's interesting none 209 00:09:55,759 --> 00:09:54,149 of these would be a surprise to you 210 00:09:57,350 --> 00:09:55,769 especially to your psychiatrist and 211 00:09:59,479 --> 00:09:57,360 psychologists in the group none of these 212 00:10:03,499 --> 00:09:59,489 would be surprised a surprise for 213 00:10:05,600 --> 00:10:03,509 patients with repeated head injuries but 214 00:10:08,269 --> 00:10:05,610 all of these players were having real 215 00:10:10,460 --> 00:10:08,279 difficulty they couldn't hold jobs they 216 00:10:12,530 --> 00:10:10,470 were divorced they couldn't make it 217 00:10:14,600 --> 00:10:12,540 maintain a relationship with their 218 00:10:17,179 --> 00:10:14,610 girlfriends one of them is a very 219 00:10:18,979 --> 00:10:17,189 well-known sports broadcaster who was 220 00:10:21,169 --> 00:10:18,989 having trouble remembering names and 221 00:10:23,449 --> 00:10:21,179 numbers that's a problem for a 222 00:10:25,189 --> 00:10:23,459 sportscaster and he was certainly 223 00:10:27,259 --> 00:10:25,199 concerned about losing his job 224 00:10:30,350 --> 00:10:27,269 they couldn't concentrate they had 225 00:10:33,650 --> 00:10:30,360 headaches this is really really a tough 226 00:10:35,659 --> 00:10:33,660 situation so we asked these guys if they 227 00:10:37,519 --> 00:10:35,669 would be willing to take slo drops one 228 00:10:40,609 --> 00:10:37,529 drop four times a day one after each 229 00:10:42,769 --> 00:10:40,619 meal one before bed with all of our 230 00:10:45,259 --> 00:10:42,779 patients for whatever disorder or 231 00:10:46,970 --> 00:10:45,269 whatever therapeutic agent were using we 232 00:10:49,369 --> 00:10:46,980 find that for the first two weeks they 233 00:10:51,590 --> 00:10:49,379 are as compliant as can be after that to 234 00:10:52,850 --> 00:10:51,600 get bored taking drops and so forth so 235 00:10:54,949 --> 00:10:52,860 we're hoping that they would take at 236 00:10:57,049 --> 00:10:54,959 least two drops a day put the dart and 237 00:10:58,519 --> 00:10:57,059 drop a bottle by your toothbrush hope 238 00:11:00,350 --> 00:10:58,529 you do brush your teeth twice a day take 239 00:11:02,590 --> 00:11:00,360 one morning in one at night so they did 240 00:11:05,059 --> 00:11:02,600 within two weeks we usually saw a change 241 00:11:07,680 --> 00:11:05,069 or as a slight change they were 242 00:11:11,430 --> 00:11:07,690 reporting changes all the symptoms would 243 00:11:12,810 --> 00:11:11,440 resolved and the sportscaster had no 244 00:11:14,010 --> 00:11:12,820 trouble after two or three weeks 245 00:11:17,820 --> 00:11:14,020 remembering whatever you wanted to 246 00:11:20,940 --> 00:11:17,830 remember no more headaches it's not to 247 00:11:23,670 --> 00:11:20,950 say that all symptoms resolved in the 248 00:11:26,310 --> 00:11:23,680 equal rate of time or that all resolved 249 00:11:27,810 --> 00:11:26,320 completely but there was resolution to 250 00:11:29,970 --> 00:11:27,820 one degree or another of all of them and 251 00:11:33,090 --> 00:11:29,980 most of them now after three years are 252 00:11:36,360 --> 00:11:33,100 all resolved it was interesting that if 253 00:11:38,460 --> 00:11:36,370 the patient got excited about in their 254 00:11:41,010 --> 00:11:38,470 improvement and got tired of taking 255 00:11:43,640 --> 00:11:41,020 drops and stopped sometimes it would be 256 00:11:46,380 --> 00:11:43,650 a regression there would be a relapse 257 00:11:50,790 --> 00:11:46,390 but that relapse would be very quickly 258 00:11:54,210 --> 00:11:50,800 reversed by reinitiating the drops nice 259 00:11:57,810 --> 00:11:54,220 no adverse effects now typical with our 260 00:12:00,450 --> 00:11:57,820 group is if we have a new idea that we 261 00:12:02,460 --> 00:12:00,460 think would be useful clinically we try 262 00:12:04,080 --> 00:12:02,470 it on humans if it looks safe and 263 00:12:07,590 --> 00:12:04,090 there's some positive results then we do 264 00:12:10,560 --> 00:12:07,600 animal testing it's a little little bit 265 00:12:14,580 --> 00:12:10,570 backwards and then some people do but 266 00:12:17,490 --> 00:12:14,590 yeah that's worked out well for us so 267 00:12:20,130 --> 00:12:17,500 just in the last two or three months 268 00:12:21,780 --> 00:12:20,140 we've started working with a group from 269 00:12:23,910 --> 00:12:21,790 a university some of you have heard of 270 00:12:26,520 --> 00:12:23,920 it it's called Harvard that has an 271 00:12:28,860 --> 00:12:26,530 animal model for traumatic brain injury 272 00:12:31,440 --> 00:12:28,870 and they've agreed to cooperate with us 273 00:12:34,350 --> 00:12:31,450 and see what we can do what happens in 274 00:12:38,160 --> 00:12:34,360 this model is you induce brain injury 275 00:12:39,750 --> 00:12:38,170 you can do it at mild moderate or severe 276 00:12:42,750 --> 00:12:39,760 injury a pneumatically controlled 277 00:12:46,200 --> 00:12:42,760 metered force bang's of the mouse in the 278 00:12:48,000 --> 00:12:46,210 head you can do it once multiple times 279 00:12:49,620 --> 00:12:48,010 however you want to do it to try and 280 00:12:53,550 --> 00:12:49,630 reproduce what happens in a human 281 00:12:57,240 --> 00:12:53,560 situation so we had three groups of 282 00:12:59,579 --> 00:12:57,250 animals in our first round one we we 283 00:13:02,040 --> 00:12:59,589 damage and treat with SLO one group gets 284 00:13:05,010 --> 00:13:02,050 damaged and only saline then the third 285 00:13:08,160 --> 00:13:05,020 group gets into the retainer but is not 286 00:13:10,650 --> 00:13:08,170 damaged and then gets saline therapy 287 00:13:13,500 --> 00:13:10,660 okay so that's a sham control shame 288 00:13:14,820 --> 00:13:13,510 injury and these are the things we 289 00:13:16,260 --> 00:13:14,830 wanted to measure and again this is just 290 00:13:18,660 --> 00:13:16,270 a screen to see if it's worth pursuing 291 00:13:20,070 --> 00:13:18,670 just like really the five football 292 00:13:20,940 --> 00:13:20,080 players were a screen to see if it's 293 00:13:23,190 --> 00:13:20,950 worth pursuing this 294 00:13:26,070 --> 00:13:23,200 notion of treating traumatic brain 295 00:13:28,080 --> 00:13:26,080 injury with SLO so we wanted a major 296 00:13:29,460 --> 00:13:28,090 balanced spatial and performance memory 297 00:13:30,840 --> 00:13:29,470 and then look at the astrology 298 00:13:35,850 --> 00:13:30,850 sacrificed the animals and see what's 299 00:13:39,740 --> 00:13:35,860 happening in the brain here's what's 300 00:13:43,200 --> 00:13:39,750 happening all parameters improved 301 00:13:45,510 --> 00:13:43,210 balance improved in ten days after the 302 00:13:48,150 --> 00:13:45,520 after the start of therapy this next 303 00:13:50,730 --> 00:13:48,160 point is really interesting the treated 304 00:13:52,890 --> 00:13:50,740 animals improve with balance so that was 305 00:13:55,620 --> 00:13:52,900 even better than the Sham controls that 306 00:13:56,850 --> 00:13:55,630 had never been injured you know I don't 307 00:13:58,800 --> 00:13:56,860 know how you go figure that it doesn't 308 00:13:59,490 --> 00:13:58,810 really matter but the point is they were 309 00:14:01,650 --> 00:13:59,500 as good as new 310 00:14:05,940 --> 00:14:01,660 so to speak if not a little bit better 311 00:14:07,830 --> 00:14:05,950 than new memory parameters have improved 312 00:14:10,530 --> 00:14:07,840 and again they're back to normal after 313 00:14:12,570 --> 00:14:10,540 about three weeks of therapy and this is 314 00:14:16,320 --> 00:14:12,580 memory for both spatial and performance 315 00:14:18,540 --> 00:14:16,330 memory and this slide is about ten days 316 00:14:23,280 --> 00:14:18,550 old so that last dot point is incorrect 317 00:14:30,300 --> 00:14:23,290 we do have histology report results back 318 00:14:33,060 --> 00:14:30,310 now and the the result is that there is 319 00:14:38,010 --> 00:14:33,070 decrease gliosis in the treated animals 320 00:14:40,170 --> 00:14:38,020 now gliosis is defined as being an 321 00:14:42,480 --> 00:14:40,180 accumulation of nervous tissue in the 322 00:14:45,180 --> 00:14:42,490 central nervous system we're not 323 00:14:46,290 --> 00:14:45,190 convinced that that definition is 324 00:14:49,770 --> 00:14:46,300 accurate anymore 325 00:14:52,530 --> 00:14:49,780 we think that gliosis is going to refer 326 00:14:55,170 --> 00:14:52,540 to the accumulation really of brain scar 327 00:14:59,580 --> 00:14:55,180 tissue in the central nervous system as 328 00:15:05,210 --> 00:14:59,590 a consequence of injury and we're seeing 329 00:15:11,270 --> 00:15:08,340 again even with the mice no adverse 330 00:15:14,850 --> 00:15:11,280 effects so we have had patients with 331 00:15:18,000 --> 00:15:14,860 external and then internal scars on this 332 00:15:20,460 --> 00:15:18,010 therapy of slo for years and we've never 333 00:15:23,100 --> 00:15:20,470 seen an adverse effect we now have the 334 00:15:26,070 --> 00:15:23,110 traumatic brain injury patients who are 335 00:15:28,500 --> 00:15:26,080 few and Forwell three years for the 336 00:15:30,360 --> 00:15:28,510 football players no adverse effects and 337 00:15:32,700 --> 00:15:30,370 we have done animal work just on the 338 00:15:34,040 --> 00:15:32,710 toxicology and we have gone up to five 339 00:15:36,320 --> 00:15:34,050 thousand times our No 340 00:15:38,889 --> 00:15:36,330 dose given IV and still no adverse 341 00:15:41,150 --> 00:15:38,899 effects so er confident is fairly safe 342 00:15:43,100 --> 00:15:41,160 this is what we have planned in the near 343 00:15:46,610 --> 00:15:43,110 future we want to continue our 344 00:15:49,370 --> 00:15:46,620 collaborative work increase the size of 345 00:15:51,019 --> 00:15:49,380 the mouse experiments we want to look at 346 00:15:55,280 --> 00:15:51,029 animals with varying degrees of injury 347 00:15:58,490 --> 00:15:55,290 and we also want to have various start 348 00:16:00,079 --> 00:15:58,500 times for SLO therapy that is to say t0 349 00:16:01,970 --> 00:16:00,089 right after the time of injury maybe 350 00:16:05,420 --> 00:16:01,980 even before the time of injury and then 351 00:16:07,670 --> 00:16:05,430 30 60 90 days after injury to start 352 00:16:10,940 --> 00:16:07,680 therapy I should mention that there is 353 00:16:13,120 --> 00:16:10,950 an advantage in humans to starting SLO 354 00:16:15,199 --> 00:16:13,130 therapy before surgery for example 355 00:16:16,550 --> 00:16:15,209 knowing now that we've had years of 356 00:16:19,490 --> 00:16:16,560 experience and the physicians on our 357 00:16:22,730 --> 00:16:19,500 group will consistently report that 358 00:16:25,220 --> 00:16:22,740 patients on SLO therapy before surgery 359 00:16:27,650 --> 00:16:25,230 will heal more quickly than would be 360 00:16:30,410 --> 00:16:27,660 anticipated they need very little in the 361 00:16:32,690 --> 00:16:30,420 way of analgesics and you don't get any 362 00:16:37,639 --> 00:16:32,700 complications that would be associated 363 00:16:38,990 --> 00:16:37,649 with untoward scar tissue we're going to 364 00:16:41,260 --> 00:16:39,000 expand the human treated population 365 00:16:44,030 --> 00:16:41,270 we've had to turn away football players 366 00:16:46,670 --> 00:16:44,040 that want to get into this study we're 367 00:16:49,280 --> 00:16:46,680 working with a little more formal way 368 00:16:53,269 --> 00:16:49,290 now are setting up to where we will have 369 00:16:57,620 --> 00:16:53,279 we hope nearly a hundred patients 370 00:17:01,040 --> 00:16:57,630 involved and we badly need to do more in 371 00:17:03,440 --> 00:17:01,050 the way of full psychological and 372 00:17:05,240 --> 00:17:03,450 physiological work ups before during and 373 00:17:07,189 --> 00:17:05,250 after therapy what I've told you about 374 00:17:09,409 --> 00:17:07,199 our TBI work is really screening work 375 00:17:11,620 --> 00:17:09,419 but all the screening looks positive so 376 00:17:14,419 --> 00:17:11,630 we're we're fairly excited about this 377 00:17:17,659 --> 00:17:14,429 because as far as we know there's 378 00:17:20,150 --> 00:17:17,669 nothing else in the world literally that 379 00:17:22,730 --> 00:17:20,160 addresses this problem it is a big 380 00:17:24,740 --> 00:17:22,740 problem I've talked with directors of 381 00:17:27,530 --> 00:17:24,750 veteran administration hospitals who 382 00:17:28,909 --> 00:17:27,540 said who say come to our hospitals we 383 00:17:31,280 --> 00:17:28,919 have whole Ward's of people who can work 384 00:17:34,730 --> 00:17:31,290 with so this is what we are up to the 385 00:17:36,830 --> 00:17:34,740 last thing we want to do not last thing 386 00:17:38,990 --> 00:17:36,840 on a dot points not necessarily last in 387 00:17:41,510 --> 00:17:39,000 terms of importance is we're interested 388 00:17:44,480 --> 00:17:41,520 in what happens with SLO treatment for 389 00:17:47,600 --> 00:17:44,490 what might be called normal age-related 390 00:17:51,110 --> 00:17:47,610 dementia will it do anything 391 00:17:53,539 --> 00:17:51,120 we know that with normal aging the brain 392 00:17:55,430 --> 00:17:53,549 shrinks that's been nicely measured 393 00:17:57,799 --> 00:17:55,440 there's a question as to whether that 394 00:17:59,810 --> 00:17:57,809 shrinkage is directly associated with 395 00:18:02,450 --> 00:17:59,820 loss of cognition memory and things of 396 00:18:05,299 --> 00:18:02,460 that sort we want to know what happens 397 00:18:07,880 --> 00:18:05,309 with slo to the brain of the so-called 398 00:18:10,430 --> 00:18:07,890 normal person so that's the normal 399 00:18:20,050 --> 00:18:10,440 elderly person that's what we have in 400 00:18:24,830 --> 00:18:22,790 thank you John questions for John a 401 00:18:28,130 --> 00:18:24,840 quick anecdote as people go up to the 402 00:18:30,740 --> 00:18:28,140 mic I went through a glass window a 403 00:18:34,970 --> 00:18:30,750 glass door when I was 10 years old that 404 00:18:37,310 --> 00:18:34,980 was a few weeks ago and John gave me 405 00:18:39,050 --> 00:18:37,320 some s I had a big scar across my wrist 406 00:18:42,110 --> 00:18:39,060 I almost bled to death they couldn't 407 00:18:47,080 --> 00:18:42,120 stitch me back together I'll show you 408 00:18:56,950 --> 00:18:47,090 [Music] 409 00:19:00,920 --> 00:18:56,960 scars : I was reluctant to accept your 410 00:19:02,780 --> 00:19:00,930 it's interesting question individual 411 00:19:04,820 --> 00:19:02,790 physicians and veterinarians have been 412 00:19:06,320 --> 00:19:04,830 very eager to embrace it because they 413 00:19:08,720 --> 00:19:06,330 know number one it's safe and there are 414 00:19:10,340 --> 00:19:08,730 not many alternatives the Food and Drug 415 00:19:12,920 --> 00:19:10,350 Administration has been a little bit 416 00:19:17,720 --> 00:19:12,930 resistant because it's so darn new and a 417 00:19:20,090 --> 00:19:17,730 different approach but I think in in not 418 00:19:22,640 --> 00:19:20,100 being flippant to your question the 419 00:19:25,790 --> 00:19:22,650 mainstream has not had an opportunity to 420 00:19:28,790 --> 00:19:25,800 evaluate it to see we have published a 421 00:19:30,470 --> 00:19:28,800 few papers about this we do get requests 422 00:19:33,350 --> 00:19:30,480 every time we publish we get requests 423 00:19:36,070 --> 00:19:33,360 from practitioners to try it you know on 424 00:19:38,330 --> 00:19:36,080 patients not as part of any study 425 00:19:40,340 --> 00:19:38,340 frankly I think once we get it through 426 00:19:41,870 --> 00:19:40,350 the FDA and we do have what's called an 427 00:19:43,820 --> 00:19:41,880 IND in place with the Food and Drug 428 00:19:45,140 --> 00:19:43,830 Administration now I think once we get 429 00:19:46,610 --> 00:19:45,150 that through I don't I don't believe 430 00:19:48,830 --> 00:19:46,620 we're going to have much resistance in 431 00:19:53,350 --> 00:19:48,840 part because there just isn't much else 432 00:19:55,610 --> 00:19:53,360 and we have an ever older population and 433 00:19:59,230 --> 00:19:55,620 people are getting afraid and I think we 434 00:20:03,410 --> 00:19:59,240 could help yes sir 435 00:20:05,000 --> 00:20:03,420 thank you it's really fascinating but 436 00:20:09,560 --> 00:20:05,010 I'm wondering given what you did what 437 00:20:11,140 --> 00:20:09,570 you have told us about the the interest 438 00:20:15,830 --> 00:20:11,150 that people have in getting in on these 439 00:20:19,070 --> 00:20:15,840 experiments it seems to me that that 440 00:20:22,700 --> 00:20:19,080 further torturing and sacrificing of the 441 00:20:26,330 --> 00:20:22,710 animals is marginal in terms of its 442 00:20:28,750 --> 00:20:26,340 morality and I think the fact that we 443 00:20:31,030 --> 00:20:28,760 use the word sacrifice instead of kill 444 00:20:33,340 --> 00:20:31,040 indicates that we're trying to 445 00:20:36,190 --> 00:20:33,350 hope that in some sort of a religious 446 00:20:38,500 --> 00:20:36,200 patina so I wonder whether whether it be 447 00:20:41,110 --> 00:20:38,510 possible for you to consider not doing 448 00:20:45,130 --> 00:20:41,120 that part of it it's an interesting 449 00:20:50,230 --> 00:20:45,140 point and our interest is helping 450 00:20:54,880 --> 00:20:50,240 patients unfortunately in order for us 451 00:20:57,010 --> 00:20:54,890 as a dinky company to get something that 452 00:21:01,270 --> 00:20:57,020 as the previous question asked about 453 00:21:05,110 --> 00:21:01,280 getting something accepted the FDA and 454 00:21:07,270 --> 00:21:05,120 others asked for preclinical proof that 455 00:21:10,030 --> 00:21:07,280 this works and what they mean by 456 00:21:13,270 --> 00:21:10,040 preclinical is animal experimentation 457 00:21:14,950 --> 00:21:13,280 and you're right 458 00:21:17,500 --> 00:21:14,960 if these football players are getting 459 00:21:20,050 --> 00:21:17,510 better and other patients are doing well 460 00:21:22,210 --> 00:21:20,060 why on earth do you need to do any 461 00:21:24,790 --> 00:21:22,220 animal work from a practical standpoint 462 00:21:28,600 --> 00:21:24,800 you don't from a regulatory standpoint 463 00:21:30,610 --> 00:21:28,610 you do and we're stuck it's it's a 464 00:21:34,180 --> 00:21:30,620 bummer but that's just the way it is I'm 465 00:21:35,710 --> 00:21:34,190 afraid John could you tell answer two 466 00:21:37,810 --> 00:21:35,720 questions one could you give me the 467 00:21:39,750 --> 00:21:37,820 molecular weight of SLO and two what is 468 00:21:43,150 --> 00:21:39,760 the dose you're giving to people yeah 469 00:21:47,980 --> 00:21:43,160 molecular weights about sixty nine 470 00:21:52,330 --> 00:21:47,990 thousand Dalton and the dose a dose is 471 00:21:54,220 --> 00:21:52,340 about I can't tell you I will tell you 472 00:21:58,480 --> 00:21:54,230 but this is gonna be false and I'll tell 473 00:22:03,010 --> 00:21:58,490 you why we when we make up the medicine 474 00:22:06,790 --> 00:22:03,020 it's made up to a dose of about 1.6 and 475 00:22:09,550 --> 00:22:06,800 nanograms per dose and I say that that 476 00:22:13,030 --> 00:22:09,560 is false because the vast majority of 477 00:22:16,720 --> 00:22:13,040 the SLO that goes into the vial adheres 478 00:22:19,150 --> 00:22:16,730 to the glass so we have spent two years 479 00:22:21,430 --> 00:22:19,160 and a bunch of numbers of hundreds of 480 00:22:23,980 --> 00:22:21,440 thousands of dollars to develop what's 481 00:22:26,560 --> 00:22:23,990 called a release assay which the FDA 482 00:22:28,210 --> 00:22:26,570 rightly requires to prove that what was 483 00:22:31,900 --> 00:22:28,220 in the vial at the start is still there 484 00:22:32,860 --> 00:22:31,910 at the end and for us it's not so we 485 00:22:34,420 --> 00:22:32,870 have to go with what's called a 486 00:22:37,560 --> 00:22:34,430 functional assay and as dr. Ives 487 00:22:39,850 --> 00:22:37,570 mentioned we're we're way below 488 00:22:40,820 --> 00:22:39,860 Avogadro's number I do believe in what's 489 00:22:42,710 --> 00:22:40,830 left in 490 00:22:46,070 --> 00:22:42,720 by oh that's why we're going to have to 491 00:22:48,529 --> 00:22:46,080 go to a functional assay instead of the 492 00:22:55,549 --> 00:22:48,539 typical chemical assay for for dosing 493 00:22:59,779 --> 00:22:55,559 thank you hello I don't know any of the 494 00:23:02,389 --> 00:22:59,789 a lot about 22 brain injury but there's 495 00:23:07,810 --> 00:23:02,399 a fellow who I a client that I work with 496 00:23:10,460 --> 00:23:07,820 who in a psychiatric program who has 497 00:23:13,129 --> 00:23:10,470 brain injury from a child that was hit 498 00:23:16,909 --> 00:23:13,139 by a car or something and he hears 499 00:23:19,039 --> 00:23:16,919 voices and his family says that that he 500 00:23:23,419 --> 00:23:19,049 said that the voices began after the 501 00:23:26,060 --> 00:23:23,429 injury number one is that a symptom and 502 00:23:29,720 --> 00:23:26,070 number two do you have you experienced 503 00:23:31,789 --> 00:23:29,730 any alleviation of that symptom we have 504 00:23:34,279 --> 00:23:31,799 and even in the small number of football 505 00:23:37,039 --> 00:23:34,289 players we have one of the reasons why a 506 00:23:39,440 --> 00:23:37,049 couple of them had trouble holding jobs 507 00:23:41,360 --> 00:23:39,450 or maintaining interpersonal 508 00:23:43,610 --> 00:23:41,370 relationships was just that sort of 509 00:23:45,919 --> 00:23:43,620 problem and that's not I don't mean to 510 00:23:49,279 --> 00:23:45,929 imply for a second that SLO is the 511 00:23:51,830 --> 00:23:49,289 panacea for all brain problems but if 512 00:23:53,960 --> 00:23:51,840 they are ones caused by traumatic brain 513 00:24:00,000 --> 00:23:53,970 injury at least we have a chance to help 514 00:24:05,030 --> 00:24:02,880 well I've got one small bottle and we 515 00:24:08,299 --> 00:24:05,040 can take bids
