Great Point Partners, LLC Remains Opposed To The BioCryst Pharmaceutical Proposed Merger With Idera Pharmaceuticals, Inc.
 
(June 20, 2018)

GREENWICH, Conn., June 20, 2018 /PRNewswire/ --Great Point Partners, LLC ("GPP") today submitted a letter to the Board of Directors of BioCryst Pharmaceuticals, Inc. ("BCRX") expressing its continued opposition to BCRX's proposed merger with Idera Pharmaceuticals, Inc. The full text of the letter can be found below and is attached as an exhibit to GPP's Schedule 13D, which was filed today.

To the Board of Directors of BioCryst Pharmaceuticals, Inc. ("BCRX"):

As you are aware from our prior letter1, we strongly believe the proposed merger with Idera Pharmaceuticals, Inc. ("IDRA") is disadvantageous to the shareholders of BioCryst. Given the unusual step taken of delaying the merger vote, the resulting passage of time, and the major changes in circumstances since the original announcement, we write to you again to reiterate our negative stance, which is only solidified by recent developments discussed here.



1. The Idera Pipeline Has Suffered Meaningful Setbacks Since The Original Merger Announcement:

At the announcement of the proposed merger, BioCryst and Idera advocated that a combined entity brings diversification to shareholders, something we still believe is not desired by shareholders, even if it were delivered by this transaction. On slide 7 of the presentation made to the public, BCRX and IDRA identified eight specific compounds with identified indications in formal preclinical or clinical testing.2 Four are from BioCryst, and four are from Idera. Since then, all four BioCryst assets/programs continue on their targeted development timeline. The same cannot be said about any of Idera's programs.

a. "IMO-2125 in PD-1 Refractory Melanoma in combination with ipilimumab"

As we stated in our original letter, we believe IMO-2125 has a completely different, and higher, risk profile than BCX-7353, and therefore significantly increases risk for BCRX shareholders exchanging their shares for those of the proposed NewCo. Our view has only been further confirmed with the ASCO 2018 update. Since the update at SITC in November 2017 (the latest data available as of the original merger announcement date), the Overall Response Rate ("ORR") reported by Idera dropped from 50% in the first 10 patients treated to 27% in the next 11 patients treated, a reduction of nearly 50%, raising significant questions about whether or not the ORR will drop even further with the addition of even more patients.3

note: one CR was still unconfirmed as of ASCO 2018



Calculating an industry-standard two-sided 95% exact binomial confidence interval around the updated blended 38% ORR yields (18.1%, 61.6%). In other words, it is extraordinarily unrealistic, at this time, to have confidence in what the true response rate will be. It could be as low as 18.1% which is just under half the observed 38% point estimate.

Moreover, we believe you should have reminded investors that even this 38% reported ORR is only a subset of the patients treated in this trial. We know that 9 patients were treated at other doses: 3 each at half the strength (4mg), double the strength (16mg), and quadruple the strength (32mg). Typically, in earlier stage oncology studies, the go-forward dose is the maximum tolerated dose ("MTD"), because higher doses are more effective than lower doses (a "dose response"). While we acknowledge that with certain mechanisms, there could be a "U-shaped" dose response curve, where neither low nor high doses are more efficacious than a mid-dose, it is very rare in oncology. With IMO-2125, no such pre-specified mechanistic rationale was put forth. No MTD has been reached, as far as we can tell from past data disclosures. Without any clear explanation at this time for why 8mg is the dose most likely to be better for patients than 4mg, 16mg or 32mg, we think it is relevant and important to consider the response rates for these other doses, as presented at SITC 2017: 1 out of 3 patients at 4mg, 0 out of 3 patients at 16mg, and 0 out of 3 patients at 32mg.

The perils of relying on single arm, open label studies have been the subject of innumerable Wall Street analyst research reports going into and coming out of ASCO, particularly considering high profile test drugs including in melanoma that originally showed "promising" single arm ORR data, only to have either disappointed with the addition of more patients, or failed spectacularly in the controlled, blinded outcomes studies. As a result of the greater uncertainty broadly in the immuno-oncology space in which Idera operates, stock prices of companies in this field have fallen a median of 20% since the merger announcement (See Table 1 at the end of the letter).

b. "IMO-8400 Dermatomyositis"

On June 12, 2018, IDRA issued a press release stating that the Phase II double-blind, placebo-controlled trial failed.4 There is no mention of next steps, which we interpret to mean there are none and that the program is being discontinued.

c. "IMO-2125 Solid Tumor Monotherapy"

According to Idera's most recent 10Q5 and 10K6, the Phase Ib solid tumor monotherapy trial of IMO-2125 began 15 months ago. Even though the company has presented interim data several times from the IMO-2125 + ipilimumab study over this time frame, we still have seen no results at all from this monotherapy trial. Enrollment in the first and second dose cohorts were completed in February 2018. We believe ASCO 2018 would have been a perfect venue at which to share data from this study, and the omission of such an update, particularly as the company is pursuing this merger, is an indication to us that IMO-2125 has shown little to no activity in at least the first 16 patients treated.

d. "IDRA-008 Liver Target"

In its 10Q filing for the first quarter of 2018, IDRA disclosed: "we completed our pre-clinical analysis for IDRA-008 and based upon the outcome of pre-clinical pharmacology studies, including a comparative pharmacology study with the competitive development asset Volanesorsen, and IND-enabling safety evaluation, we made a data-driven decision to not advance IDRA-008 into clinical development."

In summary, since the merger proposal was announced 5 months ago, risks surrounding IMO-2125 in PD-1 refractory melanoma have risen even further, the monotherapy study has likely not yet shown any activity, and the two other programs are discontinued due to failure.

2.Market View Has Been Made Clear and No Renegotiation Has Occurred: As of June 19, 2018, and since the day the merger proposal was announced, Idera's stock has fallen 42% and BioCryst stock has risen 7%. What was originally contemplated as a merger of equals is now completely lopsided as BCRX shareholders will be forced to subsidize the loss of over $250M in Idera market value. As of June 19, 2018, BCRX and IDRA have fully diluted market capitalizations of $675M and $390M, respectively. A merger at relative value equivalence would result in BCRX shareholders owning 63.4% of the combined company, not the 51.6% contemplated in the original proposal. Moreover, we believe BCRX's valuation has been held down by the possibility of this merger as evidenced by the fact that the Russell 2000 Biotechnology Index is up 20% since the merger proposal was announced, and as cited above, immuno-oncology companies have been devalued by 20% over that time period, while on average, drug development companies outside the immuno-oncology space have increased in value.

3.IMO-2125 Does Not Generate Cash: On June 5, 2018, BioCryst issued a most unfortunate letter to stockholders contending that the merger will enhance shareholder value.7 As highlighted above, we believe that the combined entity will not diversify risk, will not bolster the development pipeline, and will not create the synergies about which management speculated since the day the deal was discussed with the public on the initial conference call. The letter further talks about "the cash generated by Idera's IMO-2125 program", and how that cash might be used to invest in BCX-7353. To the best of our knowledge, IMO-2125 is a development stage asset, consuming enormous cash resources, and is the main reason that both (a) IDRA has stated its current cash runs out in mid 2019 and (b) the proxy statement models IDRA needing $300M in 2019-2020. If the Board is aware of cash that is being generated by IMO-2125, it is incumbent upon the Board to share such information with shareholders.

4.BioCryst Adjusted Idera Projections Are Misleading: Lastly, the proxy statement was filed subsequent to our initial letter, and we would like to highlight the BioCryst Adjusted Idera Projections on pages 82-838. As far as we are aware, IMO-2125 has never been studied in Head & Neck cancer or Bladder cancer. However, the projections actually assume Head & Neck and Bladder cancer sales will account for over 50% of total IMO-2125 revenue starting in 2025. We find it utterly baseless and wildly inconsistent with industry norms to assign value to a drug candidate for indications in which it has never even been studied.

In summary, our equity ownership has not changed, we continue to believe that the proposed merger is not in the best interest of BCRX shareholders, and we intend to vote against it. We postulate that the decision to delay the merger vote was a result of both (a) other shareholders also expressing their discontent with the proposed merger, and (b) management's hope (ultimately unrealized) that new information, could, on this post hoc basis, save the merger. It is clear that it cannot. We believe the recent developments only further support our original stance that the merger is significantly unbalanced and represents a substantial transfer of highly valuable BCRX assets to the shareholders of IDRA in exchange for more speculative IDRA assets of far more uncertain value.

Table 1

We include only those companies that have trading histories from the day prior to the IDRA/BCRX merger announcement through 6/19/18, and have valuations largely driven by their IO technologies. We exclude cell therapy (for example, CAR-T) and targeted therapy companies (for example, targeted kinase inhibitors). Over 70% of companies lost value, and 80% under-performed the Russell 2000 Biotech Index.
