1 00:00:05,430 --> 00:00:03,750 this morning we have some news about 2 00:00:07,829 --> 00:00:05,440 developments resulting from a space 3 00:00:10,150 --> 00:00:07,839 station science experiment that began 4 00:00:12,629 --> 00:00:10,160 more than 11 years ago 5 00:00:15,589 --> 00:00:12,639 the micro encapsulation electrostatic 6 00:00:17,349 --> 00:00:15,599 processing system or meps was recently 7 00:00:19,750 --> 00:00:17,359 cited by international space station 8 00:00:22,070 --> 00:00:19,760 chief scientist dr julie robinson as 9 00:00:23,750 --> 00:00:22,080 number one on her list of the top 10 10 00:00:26,710 --> 00:00:23,760 research results on the space station 11 00:00:28,630 --> 00:00:26,720 during its first 15 years in space that 12 00:00:31,509 --> 00:00:28,640 was a space station science experiment 13 00:00:33,590 --> 00:00:31,519 that flew during expedition 5. 14 00:00:35,670 --> 00:00:33,600 well today the company that licensed the 15 00:00:37,830 --> 00:00:35,680 meps technology for use in cancer 16 00:00:39,750 --> 00:00:37,840 treatments is moving toward human 17 00:00:42,150 --> 00:00:39,760 clinical trials in the treatment of 18 00:00:44,950 --> 00:00:42,160 breast cancer joining us today is dr 19 00:00:47,029 --> 00:00:44,960 dennis morrison a former jsc scientist 20 00:00:49,750 --> 00:00:47,039 who is the principal investigator on the 21 00:00:52,389 --> 00:00:49,760 meps he is uh now a vice president with 22 00:00:53,830 --> 00:00:52,399 new view therapeutics the company that i 23 00:00:56,150 --> 00:00:53,840 referred to 24 00:00:58,150 --> 00:00:56,160 start by telling us what it was you were 25 00:01:01,270 --> 00:00:58,160 looking to achieve when you started the 26 00:01:03,029 --> 00:01:01,280 meps research on the station in 2002 27 00:01:05,670 --> 00:01:03,039 sure perhaps 28 00:01:07,750 --> 00:01:05,680 the tendency for therapy 29 00:01:09,910 --> 00:01:07,760 in cancer treatment now is to go to 30 00:01:12,870 --> 00:01:09,920 what's called focal therapy to try to 31 00:01:15,030 --> 00:01:12,880 put a focus on the tumor itself instead 32 00:01:17,270 --> 00:01:15,040 of having to expose the body to all the 33 00:01:19,190 --> 00:01:17,280 treatment therapies so for radiation 34 00:01:21,510 --> 00:01:19,200 it's a matter of focusing the radiation 35 00:01:24,149 --> 00:01:21,520 for chemotherapy it's a techniques to be 36 00:01:25,990 --> 00:01:24,159 able to deliver the chemotherapy drugs 37 00:01:28,630 --> 00:01:26,000 directly into the tumor instead of 38 00:01:31,109 --> 00:01:28,640 having to give so much all systemically 39 00:01:33,270 --> 00:01:31,119 our approach to this was to make liquid 40 00:01:35,749 --> 00:01:33,280 filled micro balloons these are like a 41 00:01:38,069 --> 00:01:35,759 children's water balloon 42 00:01:39,990 --> 00:01:38,079 full of a cancer drug 43 00:01:42,870 --> 00:01:40,000 and a contrast agent so that you can 44 00:01:45,590 --> 00:01:42,880 actually visualize them in real time as 45 00:01:47,590 --> 00:01:45,600 they're being deposited in the tumor 46 00:01:50,230 --> 00:01:47,600 and then the outside skin rather than 47 00:01:52,630 --> 00:01:50,240 being a rubber component is made of 48 00:01:54,310 --> 00:01:52,640 biocompatible polymers that lets the 49 00:01:56,310 --> 00:01:54,320 drug slowly be released or slowly 50 00:01:59,030 --> 00:01:56,320 disintegrates over time so it disappears 51 00:02:01,109 --> 00:01:59,040 after a while a release system exactly 52 00:02:03,109 --> 00:02:01,119 so the approach was to make these unique 53 00:02:05,030 --> 00:02:03,119 micro balloons in precisely the right 54 00:02:07,350 --> 00:02:05,040 kind of quality conditions 55 00:02:09,029 --> 00:02:07,360 the difficulty was is that the way we 56 00:02:10,710 --> 00:02:09,039 elected to make them 57 00:02:13,750 --> 00:02:10,720 the different liquids three different 58 00:02:16,390 --> 00:02:13,760 liquids are different densities so on an 59 00:02:18,070 --> 00:02:16,400 earth they stratify into layers 60 00:02:19,670 --> 00:02:18,080 as a result it's hard to get them to 61 00:02:21,910 --> 00:02:19,680 come together to form little micro 62 00:02:23,270 --> 00:02:21,920 balloons and form a skin in the right 63 00:02:25,270 --> 00:02:23,280 proportions 64 00:02:27,350 --> 00:02:25,280 when we go to microgravity surface 65 00:02:29,589 --> 00:02:27,360 tension takes over and all liquids go 66 00:02:32,070 --> 00:02:29,599 spherical so it makes it much easier to 67 00:02:34,150 --> 00:02:32,080 put a sphere with another sphere and 68 00:02:36,390 --> 00:02:34,160 form a skin around the outside 69 00:02:38,390 --> 00:02:36,400 and the trick was is to be able to learn 70 00:02:40,470 --> 00:02:38,400 how to control those conditions so that 71 00:02:42,630 --> 00:02:40,480 eventually we can make them on earth and 72 00:02:44,070 --> 00:02:42,640 that was what the space interference did 73 00:02:45,670 --> 00:02:44,080 and in the space station that was the 74 00:02:47,750 --> 00:02:45,680 definitive experiments when we did eight 75 00:02:49,190 --> 00:02:47,760 experiments encapsulated seven different 76 00:02:50,390 --> 00:02:49,200 kind of drugs and a genetically 77 00:02:52,150 --> 00:02:50,400 engineered dna 78 00:02:54,309 --> 00:02:52,160 we have to have a picture that we can 79 00:02:57,030 --> 00:02:54,319 show of what that looks like 80 00:02:58,869 --> 00:02:57,040 yes on the left there are microcapsules 81 00:03:02,390 --> 00:02:58,879 that were formed in space 82 00:03:04,229 --> 00:03:02,400 containing a photodynamic therapy drug 83 00:03:06,470 --> 00:03:04,239 this is a drug that is activated after 84 00:03:07,910 --> 00:03:06,480 it's been absorbed by tumor cells on the 85 00:03:09,430 --> 00:03:07,920 right is an example with the 86 00:03:11,270 --> 00:03:09,440 fluorescence showing that those 87 00:03:13,750 --> 00:03:11,280 microcapsules are 88 00:03:16,869 --> 00:03:13,760 full of the and evenly distributed of 89 00:03:18,790 --> 00:03:16,879 the anti-cancer drug contained inside 90 00:03:20,390 --> 00:03:18,800 now it's one thing to be able to make 91 00:03:22,309 --> 00:03:20,400 that in space 92 00:03:24,470 --> 00:03:22,319 i guess the next step is how do you make 93 00:03:27,430 --> 00:03:24,480 it on earth and make enough of it so 94 00:03:29,270 --> 00:03:27,440 that it's it's it can be useful yes 95 00:03:31,190 --> 00:03:29,280 and the trick was is we had to learn how 96 00:03:32,470 --> 00:03:31,200 to control the conditions to bring these 97 00:03:34,149 --> 00:03:32,480 different liquids 98 00:03:35,830 --> 00:03:34,159 faces into 99 00:03:37,190 --> 00:03:35,840 interaction where the spontaneous would 100 00:03:39,350 --> 00:03:37,200 form the capsule 101 00:03:42,630 --> 00:03:39,360 and the microgravity experiments with a 102 00:03:44,869 --> 00:03:42,640 very variety of different conditions and 103 00:03:47,589 --> 00:03:44,879 real-time video of the capsules being 104 00:03:49,350 --> 00:03:47,599 formed in the meps device gave us the 105 00:03:51,030 --> 00:03:49,360 information to be able to develop a 106 00:03:53,110 --> 00:03:51,040 system called the pulse flow 107 00:03:54,869 --> 00:03:53,120 microcapsule system that we use on the 108 00:03:56,550 --> 00:03:54,879 ground now today and we no longer have 109 00:03:57,830 --> 00:03:56,560 to go to space in order to be able to 110 00:04:00,149 --> 00:03:57,840 make the capsules 111 00:04:02,630 --> 00:04:00,159 with the right proportions of content 112 00:04:03,830 --> 00:04:02,640 and in large quantities enough so that 113 00:04:06,470 --> 00:04:03,840 they would 114 00:04:08,869 --> 00:04:06,480 you can do uh experiments to and find 115 00:04:11,270 --> 00:04:08,879 out just how they work that's true and 116 00:04:12,710 --> 00:04:11,280 that led us to the capabilities to be 117 00:04:15,350 --> 00:04:12,720 able to explore several different 118 00:04:17,030 --> 00:04:15,360 applications for commercial use 119 00:04:18,629 --> 00:04:17,040 and we did studies with the 120 00:04:20,629 --> 00:04:18,639 microcapsules that were made and now 121 00:04:22,790 --> 00:04:20,639 made on the ground to be able to treat 122 00:04:24,070 --> 00:04:22,800 human prostate and human 123 00:04:26,390 --> 00:04:24,080 lung tumors 124 00:04:29,189 --> 00:04:26,400 in animals to define the dose the 125 00:04:30,710 --> 00:04:29,199 quantity and the sequence of how often 126 00:04:32,950 --> 00:04:30,720 you need to give these capsules because 127 00:04:34,870 --> 00:04:32,960 they actually act as a sustained release 128 00:04:37,830 --> 00:04:34,880 form releasing the drug over a period of 129 00:04:40,390 --> 00:04:37,840 10 to 12 days you brought us a little 130 00:04:41,990 --> 00:04:40,400 clip of animation that demonstrates 131 00:04:43,350 --> 00:04:42,000 shows us what this looks like when you 132 00:04:45,590 --> 00:04:43,360 when you uh 133 00:04:48,070 --> 00:04:45,600 give the drug uh yes that's that's 134 00:04:49,670 --> 00:04:48,080 correct uh let me suggest that there is 135 00:04:52,070 --> 00:04:49,680 two steps to this uh without the 136 00:04:54,550 --> 00:04:52,080 animation this is the uh 137 00:04:57,430 --> 00:04:54,560 imitation of a growing tumor with the 138 00:04:59,510 --> 00:04:57,440 small deposits those as 1 20th of one 139 00:05:02,150 --> 00:04:59,520 drop of microcapsules being deposited in 140 00:05:05,029 --> 00:05:02,160 the tumor and when it's exposed to 141 00:05:07,270 --> 00:05:05,039 near-infrared radiation light 142 00:05:08,710 --> 00:05:07,280 then the the drug is activated which 143 00:05:10,710 --> 00:05:08,720 kills the tumor 144 00:05:13,029 --> 00:05:10,720 and that particular 145 00:05:15,749 --> 00:05:13,039 technology is such those drugs are 146 00:05:17,909 --> 00:05:15,759 absorbed only by the tumor cells not by 147 00:05:18,710 --> 00:05:17,919 the human but the normal cells 148 00:05:20,629 --> 00:05:18,720 and 149 00:05:22,790 --> 00:05:20,639 the drug is totally inactive until the 150 00:05:24,629 --> 00:05:22,800 near infrared light reaches them 151 00:05:26,950 --> 00:05:24,639 now we got into that because we were 152 00:05:29,430 --> 00:05:26,960 studying the use of near-infrared light 153 00:05:31,029 --> 00:05:29,440 to stimulate uh bone cell and stimulate 154 00:05:32,629 --> 00:05:31,039 wound healing for astronaut use in 155 00:05:34,629 --> 00:05:32,639 during the station 156 00:05:36,150 --> 00:05:34,639 and that kind of a dice was developed 157 00:05:38,230 --> 00:05:36,160 here i have an example this was 158 00:05:40,469 --> 00:05:38,240 developed for nasa under a small 159 00:05:42,790 --> 00:05:40,479 business innovative research grant years 160 00:05:45,029 --> 00:05:42,800 ago and this light is set up with a 161 00:05:47,350 --> 00:05:45,039 near-infrared light same wavelength as a 162 00:05:50,150 --> 00:05:47,360 laser pointer but it penetrates deep 163 00:05:51,909 --> 00:05:50,160 into tissue as you can see 164 00:05:54,230 --> 00:05:51,919 this will actually penetrate in adequate 165 00:05:55,189 --> 00:05:54,240 quantities to be able to 166 00:05:57,430 --> 00:05:55,199 go 167 00:05:58,950 --> 00:05:57,440 five to seven inches deep in the tissue 168 00:06:01,189 --> 00:05:58,960 so it's suitable to be able to use it 169 00:06:02,950 --> 00:06:01,199 for a handheld device like this or be 170 00:06:04,469 --> 00:06:02,960 able to use it for fiber optics to 171 00:06:06,469 --> 00:06:04,479 deliver the light 172 00:06:07,990 --> 00:06:06,479 near the tumor and irradiate the our 173 00:06:09,670 --> 00:06:08,000 microcapsules that have been deposited 174 00:06:11,590 --> 00:06:09,680 there you've gone from an experiment in 175 00:06:15,029 --> 00:06:11,600 space to learning how to make the same 176 00:06:16,710 --> 00:06:15,039 product on earth in in 1g 177 00:06:18,870 --> 00:06:16,720 i understand that last week you were 178 00:06:21,270 --> 00:06:18,880 also in washington dc trying to get 179 00:06:23,670 --> 00:06:21,280 approval from the government agencies 180 00:06:26,390 --> 00:06:23,680 for the next step to try to to test 181 00:06:29,189 --> 00:06:26,400 these products in human beings that's 182 00:06:31,189 --> 00:06:29,199 correct yes and um we were with the food 183 00:06:33,110 --> 00:06:31,199 and drug administration last week and 184 00:06:34,550 --> 00:06:33,120 our initial step was to 185 00:06:37,029 --> 00:06:34,560 be proposed 186 00:06:38,390 --> 00:06:37,039 to the fda a plan to do the testing 187 00:06:41,110 --> 00:06:38,400 required 188 00:06:42,710 --> 00:06:41,120 to be able to use these microcapsules as 189 00:06:45,990 --> 00:06:42,720 a marker 190 00:06:48,550 --> 00:06:46,000 in breast biopsy sites when some breast 191 00:06:51,589 --> 00:06:48,560 tissue has been removed make a small 192 00:06:53,589 --> 00:06:51,599 deposit of a tiny quantity of our micro 193 00:06:55,670 --> 00:06:53,599 capsules when you do that we have a 194 00:06:57,830 --> 00:06:55,680 picture that sort of illustrates it um 195 00:07:00,150 --> 00:06:57,840 in a tumor tissue oh i think that's the 196 00:07:01,830 --> 00:07:00,160 next slide there that one uh yes 197 00:07:03,430 --> 00:07:01,840 in the upper left corner i don't have a 198 00:07:05,350 --> 00:07:03,440 pointer up on the corner 199 00:07:07,510 --> 00:07:05,360 um there is a 200 00:07:09,350 --> 00:07:07,520 oblong tumor there and there is a center 201 00:07:11,350 --> 00:07:09,360 in the that shows that there's 202 00:07:13,270 --> 00:07:11,360 microcapsules being deposited that was 203 00:07:15,589 --> 00:07:13,280 one twentieth of one drop and that was 204 00:07:17,110 --> 00:07:15,599 done in real time you could see when the 205 00:07:19,749 --> 00:07:17,120 microcapsules actually come out of the 206 00:07:21,430 --> 00:07:19,759 fine gauge needle wow so you can exactly 207 00:07:23,589 --> 00:07:21,440 position that 208 00:07:24,950 --> 00:07:23,599 the use there is to have it as a 209 00:07:27,909 --> 00:07:24,960 reference marker 210 00:07:29,270 --> 00:07:27,919 for future tumor biopsies in case that 211 00:07:31,189 --> 00:07:29,280 they're needed you can see with 212 00:07:33,670 --> 00:07:31,199 ultrasound imaging you can see where you 213 00:07:34,710 --> 00:07:33,680 took the first biopsy and carefully 214 00:07:37,189 --> 00:07:34,720 position where you're going to take the 215 00:07:39,270 --> 00:07:37,199 next biopsy or as an aide to the surgeon 216 00:07:40,790 --> 00:07:39,280 just before he goes ahead and excises 217 00:07:42,150 --> 00:07:40,800 and removes that tumor 218 00:07:43,670 --> 00:07:42,160 and that's the first step that we've 219 00:07:45,589 --> 00:07:43,680 approached the food drug administration 220 00:07:47,909 --> 00:07:45,599 about being able to use this in in 221 00:07:50,150 --> 00:07:47,919 patients to treat as a diagnostic tool 222 00:07:51,909 --> 00:07:50,160 for human breast cancer 223 00:07:53,830 --> 00:07:51,919 the next step of course is that the only 224 00:07:55,830 --> 00:07:53,840 difference between these marker 225 00:07:57,990 --> 00:07:55,840 microcapsules and a drug delivery one is 226 00:07:59,990 --> 00:07:58,000 we put the drug inside in the water 227 00:08:01,510 --> 00:08:00,000 content so the next step is we're doing 228 00:08:04,309 --> 00:08:01,520 this we'll be developing the same kind 229 00:08:06,629 --> 00:08:04,319 of test to show that the capsules are 230 00:08:08,469 --> 00:08:06,639 compatible with the body they're safe 231 00:08:10,629 --> 00:08:08,479 and they're effective for both imaging 232 00:08:12,550 --> 00:08:10,639 but also effective as a delivery device 233 00:08:14,070 --> 00:08:12,560 to be able to treat the tumors and our 234 00:08:15,110 --> 00:08:14,080 previous animal studies have shown that 235 00:08:16,790 --> 00:08:15,120 that's 236 00:08:19,189 --> 00:08:16,800 quite efficient 237 00:08:21,029 --> 00:08:19,199 in treating human 238 00:08:22,710 --> 00:08:21,039 lung and prostate tumors and now this 239 00:08:25,270 --> 00:08:22,720 application will be for treating human 240 00:08:27,189 --> 00:08:25,280 breast tumors be very very exciting to 241 00:08:29,510 --> 00:08:27,199 see how that progresses thank you for uh 242 00:08:31,589 --> 00:08:29,520 for for getting us up to date on this uh 243 00:08:33,670 --> 00:08:31,599 old station experiment ah thank you fat 244 00:08:35,350 --> 00:08:33,680 it's really exciting dr dennis morrison
