Registration Statement on Form S-4

Even after completion of the Merger, Tarveda will require substantial
additional funding to
finance its operations, page 41

1.     We note your disclosure here that Tarveda believes that the $13.6
million of gross
       proceeds from the December private placement of its Series 1 preferred
stock and
       recapitalization, the anticipated cash that Organovo will have on its
balance sheet at the
       effective time of the Merger, together with its existing cash and cash
equivalents as of
       September 30, 2019, will fund the combined organization's current
operating plans
       through at least the next 18 months from the anticipated effective time
of the Merger.
       Please reconcile this disclosure with the statement on page 211 that
Tarveda expects that
       its existing cash and cash equivalents, including $13.6 million of gross
proceeds from the

         December 2019 equity financing, will be sufficient to fund its
operating expenses, capital
         expenditure requirements and debt service payments through September
2020.
Background of the Merger, page 96

2.       We note your disclosure of certain discussions regarding potential
strategic alternatives
         that predated both the August 2019 announcement that Organovo would be
pursuing
         strategic alternatives and the strategic alternative process conducted
by Roth. Please
         disclose how these discussions were initiated with the various
parties.
3.       Please identify the members of the Special Committee of the Organovo
board of directors
         that was formed to evaluate strategic alternatives and establish the
material terms of the
         transaction with Tarveda.
4.       We note your disclosure that of the 27 companies that submitted
non-binding indications
         of interest, eight were invited to present to the Organovo board of
directors. Please revise
         to disclose the material terms of the bids from those eight companies
and why the special
         committee selected those eight companies. We also note your disclosure
that Organovo
         discussed and negotiated term sheets for a potential strategic
transaction with four life
         sciences companies. Please revise this section to disclose how the
material terms of the
         transaction were negotiated with those four companies, including how
the deal value,
         pricing mechanism, exchange ratio and ownership split were negotiated.
Please also
         disclose what led the special committee to select Tarveda's offer over
the other three
         parties.
5.       Please supplementally provide us with copies of all materials prepared
by Roth and shared
         with your board of directors and their representatives, including
copies of all board books
         and all transcripts and summaries, that were material to the board's
decision to approve
         the Merger Agreement.

6.       With respect to the analyses where Roth selected certain companies for
purposes of
         comparison, please disclose whether any companies meeting the
selection criteria were
         excluded from the analyses, and if so, why they were excluded.
