Baby born deaf can hear after breakthrough gene therapy – Cambridge University Hospitals
Posted: May 14, 2024 at 2:42 am
00;00;00;25 - 00;00;01;13
At four
00;00;01;13 - 00;00;05;06
weeks, when we initially heard her
00;00;05;09 - 00;00;09;02
turning to clapping, that was like
00;00;09;05 - 00;00;11;25
I was mind-blown that had worked.
00;00;11;25 - 00;00;15;18
Id sat behind Opal countless times
00;00;15;18 - 00;00;17;24
when she's had, to us, ridiculously
00;00;17;24 - 00;00;18;17
loud noises
00;00;18;17 - 00;00;20;09
blared through speakers in a sound booth
00;00;20;09 - 00;00;23;02
and she's never once turned, so to
00;00;23;02 - 00;00;28;23
see that happen is mind-blowing.
00;00;28;23 - 00;00;32;06
Good girl! Yippee!
00;00;32;09 - 00;00;34;02
Clever girl!
00;00;34;02 - 00;00;36;10
So this particular trial was for children
00;00;36;10 - 00;00;38;05
who have the OTOF gene variant
00;00;38;05 - 00;00;39;05
that does not produce
00;00;39;05 - 00;00;40;09
a particular protein
00;00;40;09 - 00;00;41;21
that they need for hearing.
00;00;41;21 - 00;00;43;06
And the surgery involves
00;00;43;06 - 00;00;43;29
approaching the ear
00;00;43;29 - 00;00;46;22
like a cochlear implant, infusing a virus
00;00;46;22 - 00;00;48;11
that makes the cells
00;00;48;11 - 00;00;50;27
produce the protein that they're missing.
00;00;50;27 - 00;00;52;02
So one thing that we've been
00;00;52;02 - 00;00;53;11
really excited about here
00;00;53;11 - 00;00;54;22
is that we've been able to use
00;00;54;22 - 00;00;57;04
a really small dose of gene therapy
00;00;57;04 - 00;00;59;07
delivered directly to the cochlear,
00;00;59;07 - 00;01;00;06
and what that means is
00;01;00;06 - 00;01;01;12
that we're not delivering
00;01;01;12 - 00;01;02;25
a large dose of gene therapy
00;01;02;25 - 00;01;04;01
to the rest of the body.
00;01;04;01 - 00;01;06;11
So it means that we see
00;01;06;11 - 00;01;07;13
fewer side effects.
00;01;07;13 - 00;01;08;10
And for Opal,
00;01;08;10 - 00;01;09;20
this is a very big change,
00;01;09;20 - 00;01;11;23
because before the gene therapy,
00;01;11;23 - 00;01;13;06
she had profound hearing loss.
00;01;13;06 - 00;01;14;04
That meant she couldn't
00;01;14;04 - 00;01;16;02
hear any sounds in that ear at all,
00;01;16;02 - 00;01;17;13
even when they were very loud.
00;01;17;13 - 00;01;18;14
And now she can hear
00;01;18;14 - 00;01;20;11
sounds at a very soft level,
00;01;20;11 - 00;01;22;02
almost in the normal range for children
00;01;22;02 - 00;01;23;13
her age.
00;01;23;13 - 00;01;24;23
Can I have a kiss?
00;01;24;23 - 00;01;31;03
Aw, good girl, daddy kiss, mummy kiss.
00;01;31;05 - 00;01;35;11
Yeah, if she doesn't have her implant
00;01;35;11 - 00;01;38;07
on, she acts exactly the same
00;01;38;07 - 00;01;39;09
as if she did have it on,
00;01;39;09 - 00;01;42;05
because she can hear so well with this
