Avidity Biosciences INVESTORS | STOCK INFORMATION DELIVERING ON OUR VISION Our mission is to profoundly improve people’s lives by delivering a new class of RNA therapeutics – AOCs. Our proprietary AOCs are designed to combine the specificity of monoclonal antibodies with the precision of oligonucleotide therapies to target the root cause of diseases previously untreatable with RNA therapeutics. Our advancing and expanding pipeline includes multiple skeletal muscle programs. We are also broadening the reach of AOCs beyond muscle tissues through both internal discovery efforts and key partnerships as the company continues to deliver on the RNA revolution.

BASIC BLOCK LEVEL ELEMENTS This is the caption for the image TOGETHER WE… BELIEVE THAT MICRORNA THERAPEUTICS WILL BECOME A MAJOR NEW CLASS OF DRUGS. WE ARE FOCUSED ON HARNESSING THEIR POWER TO TARGET MULTIPLE PATHWAYS OF DISEASE. This is a normal paragraph. To add some length to it, let us mention that this page was primarily written for testing the effect of user style sheets. You can use it for various other purposes as well, like just checking how your browser displays various HTML elements by default. It can also be useful when testing conversions from HTML format to other formats, since some elements can go wrong then. Dysregulated microRNA expression is a key factor in many complex multi-factoral diseases, including inflammatory disease, fibrosis, metabolic disease and cancer. microRNA therapeutics are oligonucleotides that modulate the function of microRNAs, correcting the imbalance of gene expression and associated cellular pathways to treat a broad range human disease.[blue_band]This is another paragraph. I think it needs to be added that the set of elements tested is not exhaustive in any sense.[/blue_band] COLUMNS column 1 column 2 Balboa Park 1915 caption microRNAs are members of a large class of non-coding RNAs of approximately 22 nucleotides in length that regulate most genes in the genome. A single microRNA can target and regulate up to hundreds of genes and these genes are involved in biological networks or pathways. [callout title=”” image=”image.png”]We design and create functional human tissues using our proprietary three-dimensional bioprinting technology. [/callout] I have selected those elements for which it can make sense to write user style sheet rules, in my opinion. LISTS One. Two. Three. Well, probably this list item should be longer. Note that for short items lists look better if they are compactly presented, whereas for long items, it would be better to have more vertical spacing between items. Four. This is the last item in this list. Let us terminate the list now without making any more fuss about it. lorum ipsum text here to show odd lorem upsum to show even This is a paragraph before a numbered list (ol). Note that the spacing between a paragraph and a list before or after that is hard to tune in a user style sheet. You can”t guess which paragraphs are logically related to a list, e.g. as a “list header”. One. Two. Three. Well, probably this list item should be longer. Note that if items are short, lists look better if they are compactly presented, whereas for long items, it would be better to have more vertical spacing between items. Four. This is the last item in this list. Let us terminate the list now without making any more fuss about it. LINKS main page Unicode Standard, chapter 6 This is a text paragraph that contains some inline links. Generally, inline links (as opposite to e.g. links lists) are problematic from the usability perspective, but they may have use as “incidental”, less relevant links. See the document Cite Link.
