are a biopharmaceutical corporation specializing in the discovery and development of therapeutics to treat stress-related neuropsychiatric
and mood disorders utilizing synthetic forms of endogenous brain signaling peptides that can dampen overactive stress responses.</FONT></P>

mechanism by which we will target these stress-related disorders is based on over 15 years of work elucidating the role of Teneurin
Carboxy-terminal Associated Peptide (&ldquo;TCAP&rdquo;), which has been found to have a central role in maintaining healthy brain
signaling. TCAP is an endogenous counterbalance to the negative effects of stress and its criticality is underscored by a high
degree of evolutionarily preservation. TCAP signaling counteracts the effects of Corticotropin Releasing Factor on the Hypothalamic-Pituitary-Adrenal
axis, thus reducing the stress hormone cortisol. We intend to bring novel forms of TCAP into human clinical development as a treatment
for stress-related neuropsychiatric disorders. Our lead compound &ndash; PT00114 &ndash; is a 41-residue peptide synthetic form
of TCAP that can be administered subcutaneously, sublingually, or intra-nasally. In addition, we have a portfolio of earlier stage
neuropeptides targeting the TCAP pathway that are in preclinical evaluation.</FONT></P>

strategy is to develop TCAP neuropeptide-based drug candidates, beginning with PT00114, in stress-related indications, including,
but not limited to: treatment resistant depression (&ldquo;TRD&rdquo;), which is a subgroup of major depressive disorder (&ldquo;MDD&rdquo;);
addiction, recidivism, or substance use disorder (&ldquo;SUD&rdquo;); anxiety, including generalized anxiety disorder (&ldquo;GAD&rdquo;),
and post-traumatic stress disorder (&ldquo;PTSD&rdquo;).</FONT></P>

intend to complete IND-enabling studies of PT00114 and to enter first-in-human Phase I/II studies in the third quarter of 2021.
We will be initiating our clinical program with a 42-patient basket trial in collaboration with Dr. Maurizio Fava, the Psychiatrist-in-Chief
of the Massachusetts General Hospital and co-principal investigator of STAR*D, the largest research study ever conducted in depression.
We will enroll a healthy human cohort and four stress-related neuropsychiatric disorders: TRD, SUD, GAD, and PTSD. We will be
using this study for both safety and preliminary efficacy signal-finding to prioritize indications for later stage development.
we&rsquo;ve chosen these four indications for multiple reasons, including direct linkage to the mechanism of TCAP in reducing
biological stress signals, preclinical evidence of efficacy in animal models of these disorders, and the high unmet need in these
patient populations, which creates significant market opportunity.</FONT></P>

time we wish to issue and sell common stock under the sales agreement, we will notify a Sales Agent of the number of shares to

we have so instructed such Sales Agent, unless the Sales Agent declines to accept the terms of such notice, the Sales Agent has
agreed to use its commercially reasonable efforts consistent with its normal trading and sales practices to sell such shares up
to the amount specified on such terms. The obligations of the Sales Agents under the sales agreement to sell our common stock

Sales Agent will provide written confirmation to us following the close of trading on the Nasdaq Capital Market, each day on which
common stock is sold under the sales agreement. Each confirmation will include the number of shares of common stock sold on that

for sales of common stock will occur, unless the parties agree otherwise, on the second business day that is also a trading day

will pay the Sales Agents an aggregate compensation equal to 3.0% of the gross proceeds we receive from the sales of our common stock.
Because there is no minimum offering amount required as a condition to close this offering, the actual total public offering amount,
commissions and proceeds to us, if any, are not determinable at this time. In connection with the sales of our common stock on our behalf,
the Sales Agents will be deemed to be &ldquo;underwriters&rdquo; within the meaning of the Securities Act, and the compensation paid
to the Sales Agents will be deemed to be underwriting commissions or discounts. We estimate that the total expenses of the offering payable
by us, excluding commissions payable to the Sales Agents under the sales agreement, will be approximately $60,000.</FONT></P>

are a biopharmaceutical corporation specializing in the discovery and development of therapeutics to treat stress-related neuropsychiatric
and mood disorders utilizing synthetic forms of endogenous brain signaling peptides that can dampen overactive stress responses.</FONT></P>

mechanism by which we will target these stress-related disorders is based on over 15 years of work elucidating the role of Teneurin Carboxy-terminal
Associated Peptide (&ldquo;TCAP&rdquo;), which has been found to have a central role in maintaining healthy brain signaling. TCAP is
an endogenous counterbalance to the negative effects of stress and its criticality is underscored by a high degree of evolutionarily
preservation. TCAP signaling counteracts the effects of Corticotropin Releasing Factor on the Hypothalamic-Pituitary-Adrenal axis, thus
reducing the stress hormone cortisol. We intend to bring novel forms of TCAP into human clinical development as a treatment for stress-related
neuropsychiatric disorders. Our lead compound &ndash; PT00114 &ndash; is a 41-residue peptide synthetic form of TCAP that can be administered
subcutaneously, sublingually, or intra-nasally. In addition, we have a portfolio of earlier stage neuropeptides targeting the TCAP pathway
that are in preclinical evaluation.</FONT></P>

strategy is to develop TCAP neuropeptide-based drug candidates, beginning with PT00114, in stress-related indications, including, but
not limited to: treatment resistant depression (&ldquo;TRD&rdquo;), which is a subgroup of major depressive disorder (&ldquo;MDD&rdquo;);
addiction, recidivism, or substance use disorder (&ldquo;SUD&rdquo;); anxiety, including generalized anxiety disorder (&ldquo;GAD&rdquo;),

view about future events. When used in this prospectus, the words &ldquo;anticipate,&rdquo; &ldquo;believe,&rdquo; &ldquo;estimate,&rdquo;
&ldquo;expect,&rdquo; &ldquo;future,&rdquo; &ldquo;intend,&rdquo; &ldquo;plan,&rdquo; or the negative of these terms and similar expressions,

contained in this prospectus relating to our business strategy, our future operating results and liquidity and capital resources outlook.
Forward-looking statements are based on our current expectations and assumptions regarding our business, the economy and other future
conditions. Because forward&ndash;looking statements relate to the future, they are subject to inherent uncertainties, risks and changes
in circumstances that are difficult to predict. Our actual results may differ materially from those contemplated by the forward-looking
statements. They are neither statements of historical fact nor guarantees of assurance of future performance. We caution you therefore
against relying on any of these forward-looking statements. Important factors that could cause actual results to differ materially from
those in the forward-looking statements include, without limitation, the results of clinical trials and the regulatory approval process;
our ability to raise capital to fund continuing operations; market acceptance of any products that may be approved for commercialization;
our ability to protect our intellectual property rights; the impact of any infringement actions or other litigation brought against us;
competition from other providers and products; our ability to develop and commercialize new and improved products and services; changes
in government regulation; our ability to complete capital raising transactions; and other factors (including the risks contained in the
section entitled &ldquo;Risk Factors&rdquo; of the applicable prospectus supplement) relating to our industry, our operations and results
of operations. Should one or more of these risks or uncertainties materialize, or should the underlying assumptions prove incorrect,
actual results may differ significantly from those anticipated, believed, estimated, expected, intended or planned.</FONT></P>
